What follows is the result of
several years work by the Panel on Consent (now known
as the "Working Committee on Consent") of the
National Council on Ethics in Human Research (NCEHR).
This document does not set out guidelines: that mandate
belongs to the Medical Research Council of Canada, the
Social Sciences and Humanities Research Council of Canada,
and the Natural Sciences and Engineering Research Council
of Canada. The issues we deal with here pertain to biomedical
and health research ethics. This work does not address
questions particular to public health, epidemiology, or
medical sociology and medical anthropology.
The idea for such a short compendium
came naturally to the group. Since the late 1980's, we
have been called upon to handle queries, usually from
Research Ethics Boards (REBs), concerning the problematic
ethical aspects of a proper approach to, and interaction
with, prospective participants in health research. We
gradually became aware that many of the queries could
have been handled with reference to a general work. This
document is meant to serve as a basic first document.
It is intended to assist medical investigators in preparing
their proposals for research, and REBs in fulfilling their
duty to review, approve or disapprove, and monitor that
research. For references that contain more detail than
is outlined in this document, we include a basic bibliography
of useful works. The Working Committee on Consent intends
to address additional areas of informed choice in future
documents.
Many individuals
associated with NCEHR have been involved in the preparation
of this document. The Panel on Consent which conceived
the idea and drafted the initial work was chaired by Janice
Dickin McGinnis and included Françoise Baylis, Douglas
Biggar, Kathleen Glass and Douglas Kinsella. They were
joined in 1994 by Janet Storch, who took over as Chair,
and Betty Flagler, who replaced outgoing member Douglas
Kinsella. When the initial draft was complete, Council
Members were offered the opportunity to comment on the
draft, and many did. Janet Storch and former NCEHR Director
Derek Jones incorporated their comments, as well as the
comments of three outside peer reviewers, to produce the
final text. Kathleen Glass prepared the document for publication.
The participation of NCEHR staff, and in particular, Louise
Dugas, was indispensable in producing the final published
texts in English and in French. Members of Council are
grateful for all of these contributions.

In working our own way through
the issues that follow, the members of the Panel on Consent
chose respect for persons as their basic value. Respect
for persons recognizes both the right of individuals to
decide for themselves, insofar as they are able, and the
obligation to protect the interests of those who are unable
to make their own decisions. The principles of autonomy,
beneficence, and non-maleficence are therefore key in
the analysis that follows.
The creation of this document
also involved the careful selection and use of language
and terminology. Wherever possible, we have limited ourselves
to the use of the words "choice" or "decision".
The term "consent" appears only in situations
where it can be taken that this particular choice has
been made. Individuals who are approached to participate
in research are being asked to make a choice, not to give
consent. Consent should not be valued over refusal since
both are equally valid choices. We have also elected to
use the phrase "research participant" rather
than subject, and "substitute decision-maker"
rather than proxy. Also, the phrase "prospective
research participant" is used in situations where
the person, or substitute decision-maker has not yet chosen
to participate. Finally, we have decided not to use the
term "patient" except in exceptional circumstances.
While many patients are research participants, many research
participants are not patients.
The following text is intended
as a discussion of factors that investigators and Research
Ethics Boards (REBs) should consider in the context of
participant consent and refusal. Although research is
a matter of great importance to the human community, decisions
to participate in it rest solely with the individual or,
in situations where the research participant is not competent,
with a substitute decision-maker. Thus, we have focused
our attention on how to ensure that the process and the
language function to allow the individual to make a competent,
informed, and voluntary decision. Sections are provided
on:
- Key Elements of Informed
Choice;
- Competence;
- Disclosure; and
- Voluntariness.
In addition to the discussion
of these key elements, we have provided draft clauses
as examples, and a checklist. Investigators and REBs are
invited to borrow or alter these to suit their purposes.

Consent as an Ethical
Imperative:
Key Elements of Informed Choice
Amorally valid choice
concerning research participation is a choice made:
- by a competent person;
- on the basis of adequate
information concerning the nature and foreseeable consequences
of the research (as these are known at the time the
request is made) and all available alternatives; and
- without controlling influences
such as "force, fraud, deceit, duress, over-reaching,
or other ulterior form of constraint or coercion"
(Nuremberg Code).
A morally valid choice is an
ongoing dialogue; it is not a form signed by the prospective
research participant or substitute decision-maker. It
is the culmination of an educational process involving
a responsible member of the research team (or contracted
person), and the prospective research participant and/or
others such as family members. It requires an affirmative
action being taken by the prospective research participant
or substitute decision-maker, not silent acquiescence.
Moreover, if the prospective research participant or substitute
decision-maker chooses to consent, then confirmation of
continuing consent may be required, as appropriate, in
recognition of the ongoing nature of the process. A morally
valid choice also includes assent, in cases where the
prospective research participant is deemed legally incompetent.
As much as it values the concept
of consent, however, a morally valid choice places equal
value on the concept of refusal: thus, it is as valid
to refuse to participate in research or to withdraw from
participation in research, as it is to agree to participate
or to continue participating.
The key elements necessary
for ensuring that a choice is morally valid include the
following:
Table
of Contents
Usually, a person invited to
participate in research must be competent. This means
that she or he must be capable of making a morally (and
legally) valid choice to participate in research. Any
assessment of the prospective research participant's ability
to make a valid choice must take into account that prospective
participant's personal life goals and values. If the prospective
participant is deemed competent to make a choice, it is
appropriate to proceed with full disclosure of the information
necessary for that person to make an informed choice about
whether or not to participate in the specific research
in question. In cases where the prospective research participant
is deemed incompetent to make a valid choice (e.g., by
virtue of insufficient age, mental illness, dementia,
or being unconsciousness), a competent substitute decision-maker
must be identified (while parents often serve in this
role for their children, this is not always the case).
The substitute decision-maker
is responsible for safeguarding the interests of the prospective
research participant in any decision to be made regarding
that person's participation in a research project. In
the case of a person who is now unable to make her or
his wishes known in this regard, but who has made those
wishes known previously (whether directly or as inferred
from behaviour), the substitute decision-maker acts for
that person's interests in making a decision consistent
with her or his understood wishes (no matter what the
personal inclination of the substitute decision-maker
might be).
In the case of a person who
is now unable to make her or his wishes known in this
regard, and who has never been able to do so, the standard
for decision-making with regard to participation in health
care interventions has been protection of the incompetent
person's "best interests" (usually interpreted
as protection of life, as well as physical and psychological
integrity). With reference to a never-competent person's
participation in research endeavours, however, there is
a question as to whether the "best interests"
standard as narrowly interpreted above should prevail.
Consistent with its statement in Reflections on Research
Involving Children (1993), NCEHR has argued that,
in matters of research, the substitute decision-maker
may authorize such participation provided there is a favourable
harm/benefit ratio. In particular cases, no more than
the potential for negligible or minimal harm to the person
would be allowed (such harm to be judged in terms of both
magnitude and probability). Any such potential harm must
have a positive balancing of potential benefit for the
group of which the person is a member, if not directly
for the person herself or himself.
As a general proposition, incompetent
persons should not be invited to participate in protocols
if competent persons would be sufficiently suitable.
Hereafter, for the purposes of this document, the phrase
"prospective research participant" when used
in the context of choice should be understood to include
the additional phrase: "and her or his substitute
decision-maker", unless otherwise stated.
Table
of Contents
In order for a choice to be
valid, it must be based upon all relevant information
concerning the proposed research. Deciding what is relevant
involves weighing alternatives. On the one hand, the researcher
must provide information concerning the purpose and nature
of the research, the potential harms and benefits of the
research, and the process of research participation. On
the other hand, the prospective research participant should
not be overwhelmed with minutiae. In addition, the prospective
research participant must be provided with specific information
concerning confidentiality, reimbursement, the right not
to participate, and the right to withdraw. Specific questions
from the prospective participant should be encouraged
and must be answered. Researchers will find guidance as
to what might and what might not be considered relevant
in the accompanying checklist which forms part of this
document.
Table
of Contents
It is imperative that the choice
made by the prospective research participant be a free
choice or, in other words, a choice that is not subject
to undue pressure or coercion. The stricture applies not
only to overt attempts at persuasion and force, but also
to situations where subtle forms of pressure and coercion
may be endemic to the environment. Examples of such potentially
coercive situations arise in dealing with captive populations
(e.g., institutionalized persons), or with patients and
their friends or family in certain hospital settings (e.g.,
neonatal ICUs or emergency rooms). Researchers in these
environments should be particularly aware of indirect
application of pressure and coercion that may occur.
Researchers who also act in
the role of the prospective research participant's physician
bear an added responsibility to ensure that any consent
given is unencumbered by feelings of patient loyalty to
the physician. Another special case is one in which limitations
in research design do not easily accommodate withdrawals
from research (e.g., when a patient is under anaesthetic,
when a research participant develops worsening dementia,
when stopping the research participants treatment
could mean an increased morbidity rate, or when somatic
cell gene transfer is underway).
Other situations involving
a differential in authority, such as professors recruiting
their own students, or employers recruiting their employees,
also require careful attention to issues regarding the
potential exertion of undue influence.
Situations such as those described
above require particular consideration by an REB as a
standard part of its review so that opportunities for
either subtle pressure or coercion to participate will
be minimized.

Responsibility of the Research Team |
The role of the research team
in soliciting an informed choice from a prospective research
participant is complex, as all three key elements of a
morally valid choice must be addressed. The competence
of the prospective research participant must be assessed,
a full disclosure of relevant information must be undertaken,
and the absence of coercion or inappropriate inducement
must be assured.
Of concern is the locus of
responsibility for the accomplishment of these tasks.
Ultimately, the principal investigator is responsible
for ensuring that prospective research participants have
an opportunity to exercise a morally valid choice. It
does not follow, however, that the principal investigator
must personally execute all or any of these tasks. These
may be delegated to the individuals who are most capable
with respect to each of the specific tasks. For example,
in cases where competence assessments are difficult, the
assessment may be delegated to a qualified member of the
research team (or contracted individual). However, the
principal investigator does maintain overall moral responsibility
for the results of delegated acts.
As regards disclosure, when
the research is relatively simple and innocuous, the principal
investigator may delegate this responsibility to another
member of the research team. However, when the proposed
research is particularly complex, the principal investigator
should be particularly careful to ensure that a very knowledgeable
member of the team (and, as appropriate, himself or herself)
assumes responsibility for this task.
Further complications arise
when the principal investigator is also the treating physician,
health professional or therapist, as this may give rise
to some concern regarding the potential for subtle coercion.
The most important or overriding consideration, however,
is that the prospective research participant be well informed.
When the best person to explain the proposed research
is both the principal investigator and the treating health
professional, a colleague should participate in the process
of obtaining the prospective research participant's informed
choice.
A separate point worthy of
note is that when the research proposal is very complex,
or extends over a long period of time, it may be appropriate
to think of the informed choice process as ongoing, in
which case the research participant periodically would
be asked to confirm her or his continuing choice regarding
research participation. This task might be appropriately
assigned to a delegate. In especially complex situations,
or when the participant may become incompetent, it may
be valuable to appoint a representative, advocate, or
ombudsperson to deal with the re-affirmation process.
Given the above, it follows
that more than one person may be involved in soliciting
an informed choice to research participation. When one
or more of those individuals involved in the process is
in a position of possible conflict of interest (e.g.,
has a commercial interest in a company sponsoring a trial),
this should be disclosed and discussed with the prospective
research participant.
As a follow-up to this overview
of informed choice as an ethical imperative, its key elements
(competence, disclosure and voluntariness) are discussed
more fully below.
Table
of Contents
Competence and Informed
Choice
Because only a competent person
can make a morally (and legally) valid choice, it is important
to ensure that any prospective research participant is
capable of making a valid choice to participate in a research
protocol. Thus a key question is: what specifically constitutes
competence?
The terms "competence"
and "capacity" are often used interchangeably.
In law, capacity refers to the recognition that certain
rights may be exercised by designated persons, and is
frequently defined by characteristics of status such as
age or civil status, as well as by the mental ability
to understand. This latter characteristic is often referred
to as mental competence or mental capacity. Because the
variability in the definitions of competence or capacity
is extremely wide, this may be cause for confusion. However,
at the core, competence/capacity is the measure of the
"fitness" of an individual to act or behave
in certain situations. In the context of research, it
means the mental ability to understand the nature and
consequences of one's acts, so as to be "fit"
to make informed choices concerning participation in research
protocols.
Since the important question
is whether the individual is fit to function in a particular
situation, such fitness is in fact determined by both
the situation and the person's understanding of it. Therefore,
incompetence in one area does not necessarily imply incompetence
in another. A prospective research participant may be
incompetent to enter into a contract or write a will,
for instance, without necessarily being incompetent to
make other choices.

| A.
Presumption of Competence |
Adults are presumed to be competent
unless evidence to the contrary is produced and accepted
by an appropriate authority. Competence or incompetence
is not a particular "diagnosis" in a medical
or psychiatric sense. A diagnosis of cerebral palsy, mental
illness, or dementia, for example, should not automatically
be accepted by health professionals as evidence of incompetence
per se. Many individuals with such diagnoses are
able to make a competent choice regarding participation
in research. Caution should be exercised in making such
determinations.
However, circumstances in which
an individual lacks sufficient cognitive ability to perform
any, or almost any, task requiring understanding do warrant
a presumption of general incompetence to make valid choices,
regardless of the protocol in question. Extreme examples
of general incompetence would be unconscious individuals,
or those completely unaware of their surroundings. Persons
in the later stages of Alzheimer's disease would also
fall into this category, given the nature of their condition.
Determinations of general incompetence
are often made in less extreme circumstances. For example,
an individual whose overall functioning is impaired by
a permanent condition such as severe mental retardation,
or a temporary condition such as being under the influence
of alcohol or drugs (prescribed or unprescribed) could
be viewed as incompetent. Persons suffering serious cognitive
impairment as the result of a stroke, who may later recover
some or all of the lost functions, also fall within this
category of prospective research participants. Other conditions,
such as certain severe psychiatric illnesses or symptoms,
might also critically impair overall functioning so that
prospective participants would be unable to make informed
choices in almost all situations, including participation
in research.
Table
of Contents
Chronological age may be a relevant
factor in making a legally valid choice; for example,
some provinces have established a statutory minimum age
for consent to one's own medical treatment. Chronological
age to consent to participate in research, however, may
differ from the age for consent to medical treatment.
Other provinces operating under common law allow all those
who have the mental ability to understand and appreciate
the nature and consequences of their acts to make their
own choices regardless of age.
Aside from fulfilling any statutory
requirement, chronological age alone should not be a consideration
for participation in research. Chronological age is relevant,
however, to the ability to act as a substitute decision-maker
for an incompetent person. Only a competent person of
legal majority may act on behalf of an incompetent person.
When a child is unable to make
a legally valid choice regarding research participation,
ordinarily his or her parents would be the legal representatives
and they would be responsible for authorizing the research
on the child's behalf.
Table
of Contents
Legal incompetence results when
a court issues an order declaring an adult person incompetent
in accordance with relevant provincial statutes, at which
time a legal representative is appointed for the person.
This representative may be a private individual or an
official such as the Public Trustee, a guardian, or a
curator. Researchers should be familiar with the requirements
of their own provinces concerning the authority of legal
representatives to authorize the participation of legally
incompetent individuals in research protocols.
All legal representatives are
charged with the responsibility for the welfare of those
they represent. Research that is clearly intended to benefit
participants is uncontroversial. However, the degree of
discomfort or risk of harm legal representatives may authorize
without corresponding benefit remains the subject of discussion
in jurisdictions that have no legislation clarifying the
matter.

Determining
Competence to Participate in Research |
Causes of incompetence are varied.
There are differences in:
- the onset of a debilitating
condition;
- the duration; and
- the effect on an individuals
ability to make an informed choice or to continue to
make informed choices over the course of a protocol.
Some conditions are life-long while others have onset
late in life.
Some are temporary; others
are permanent, with sudden or gradual onset. Only individual
evaluation can determine whether a prospective research
participant of questionable competence is able to make
a voluntary and informed choice to participate in a protocol.
As a consequence, when competency is in doubt, individual
assessment of the prospective research participant is
imperative.
While there is no single standard,
method, or formula for competency assessment, researchers
should understand that competency is assessed with respect
to the particular protocol in question. Consequently,
mental status exams or neuro-psychological exams alone
will not suffice except as screening tools which may indicate
that further assessment is warranted.
To be considered competent
to make a valid choice, prospective research participants
should be able to understand and appreciate:
- the nature and purpose of
the research in question;
- why they, as opposed to
others, are being selected and asked to participate;
- the fact that the suggested
intervention is for research purposes;
- the relevant elements of
uncertainty about the protocol;
- what participation in the
particular research protocol means for the participant;
- whether or not the intervention
may provide any direct personal benefit to them;
- how the consequences of
a decision to participate or not to participate will
affect their own current and future lives;
- that they will be free to
withdraw from participation at any time during the course
of the protocol;
- that a decision not to participate
or to withdraw from participation will not adversely
affect their care;
- any conflict of interest
on the part of the person recruiting participants; and
- the liability assumed by
the investigator.
To understand what participation
in a protocol entails, the prospective research participant
must be able not only to comprehend the physical risks,
such as physical discomforts or threats to life or health,
but also to appreciate other implications, such as alterations
to familiar routine, the necessity for hospitalization,
or restrictions on such things as diet.
In cases where prospective
research participants are likely to undergo progressive
cognitive deterioration, competence may diminish during
the operation of the protocol. It is therefore important
that they understand both the short and long range consequences
of the participation. If prospective research participants
are able to clearly comprehend all of this information,
they are competent to make a morally valid choice to participate
or refuse to participate.
However, it is possible that
an individual who could understand these elements for
one protocol may not be able to do so for another; for
example, one may be simple or involve procedures with
which the person is familiar, while the other may be more
complex or threatening. It is up to the investigator to
ensure that the research participant understands all aspects
of the particular protocol in order to establish that
the individual is competent.

Research
Involving Persons with Disabilities |
Many individuals with a disability
are competent to make their own choices. Factors such
as the loss of vision or hearing, pathologies of speech
or slowness of response, should not be confused with mental
incompetence.
Other individuals may have
a cognitive disability or, because of their young age,
may not yet have attained fully mature cognitive capacity.
In these cases their ability to make some, but not all
decisions, may be impaired. When research protocols involve
participants who do not have the necessary cognitive ability,
particular care must be taken to ensure that those able
to comprehend are presented with information in a manner
understandable to them.
In order to fulfil all disclosure
requirements for purposes of consent to research, the
communication and comprehension barriers of each prospective
research participant should be assessed. Methods of communicating
should be devised to meet the needs of every individual
who is approached to participate. Researchers must draw
up a description of their plans for assessing prospective
participants of questionable competence. Researchers must
also draw up a detailed description of the proposed process
of making a choice, including consent forms compatible
with the needs of the population from which prospective
research participants are to be drawn.
Table
of Contents
In many protocols, support of
the prospective research participant by an involved and
caring family (or other persons close to the individual)
may be required to mitigate any psychological risks and
anxieties associated with participation in a protocol.
Such support may also assist in, or even be vital for,
compliance with protocol requirements. However, researchers
should be aware of the potential for conflicts of interest
between prospective research participants and their families.
Table
of Contents
The duration of the protocol
is important, not only in consideration of possible inconvenience
to the research participant, but also in consideration
of the fact that some participants may lose competence
during the course of participation, become less competent,
or become unable to continue to express willingness to
continue participation.
Table
of Contents
| H.
Substitute Decision-Makers |
When a prospective research
participant is unable to make an informed choice, authorization
must be given by that person's legal representative. Researchers
must pay attention to the appropriateness of substitute
decision-makers. The following factors should be taken
into account:
- Investigators must comply
with applicable law(s) regarding the ability of a representative
to authorize participation by an incompetent individual
in a research protocol.
- The protocol must present
clear procedures for designation of a substitute decision-maker,
when this is necessary.
- Researchers must be sensitive
to the potential for conflicts of interest (which might
entail abuse) between the prospective participant and
her or his substitute decision-maker concerning participation
in the research protocol.
Table
of Contents
When researchers propose including
incompetent individuals as research participants, they
must justify why the research could not be carried out
reasonably well with less vulnerable participants. For
example, when protocols include young children, researchers
must explain why the research could not be done with competent
adults.
Table

Section
3 :
| Disclosure
and Informed Choice |
Respect for persons requires
that we recognize the autonomy of those able to make their
own decisions, and protect from harm those who are not.
Exercising autonomy in an informed way requires an adequate
disclosure of information. Ideally, this occurs in the
research context when participation is viewed as a partnership
between investigators and those considering entering a
protocol. This model of shared and rational decision-making
requires an exchange of essential information that fosters
informed and prudent choices by both parties. Under this
view of the research partnership, an individual informed
of the harms and benefits of participation is most likely
to make reasoned, self-protective judgements about the
assumption of risk. To do so requires the sharing of detailed
information. This attitude is supported in law, where,
because the presumed benefits of research participation
are unproven, or no benefit is intended for the participant,
the highest standard of disclosure is required. Information
provided should include what a reasonable person contemplating
participation would want to know about the consequences
and conditions of participation, including information
about the nature and probability of the potential harms
and benefits.
Table
of Contents
Information about research participation
must be provided both verbally and in writing. As well,
as much time as is necessary must be taken to ensure effective
understanding and appreciation. If the information to
be conveyed is particularly complex, audio-visual aids
and user-friendly information pamphlets may also be helpful.
If required, provision must be made for qualified interpretation
services.
To further the goal of understanding,
it is imperative that relevant information be provided:
- in the prospective research
participant's preferred language. Care should be taken
so that any interpretation or translation does not bias
the informed choice process;
- in lay terms that avoid
the overuse of medical or technical jargon (e.g. "bruise"
rather than "haematoma");
- in the first or second person
(e.g., "you" or "your child");
- at an appropriate level
for the person's age and educational level (a computer
program does exist which identifies the language used
in documents by grade level);
- with simple explanations
of clinical terms (e.g.,"a placebo is an inactive
substitute for a drug"); and
- with descriptive accounts
of relevant information (e.g., an explanation of the
level of exposure to radiation in terms of chest X-ray
equivalents, not just roentgens; a description of blood
volume required in terms of teaspoons, not just cc's).
In general, the research consent
form should not exceed three pages and should contain
both the relevant information and the actual consent form.
This combined form is preferable to separate information
and consent forms because it effectively ensures that
the prospective research participant receives the relevant
written research information.
In all cases, the individual
who consents to research must be provided with a copy
of the signed research consent form. When the research
participant is also a patient in the institution in which
the research is being conducted, the original signed form
should generally be included in the patient's record;
the researcher may only keep a copy of the signed form.
Otherwise, the original signed form should be kept on
file by the researcher.
Table
of Contents
Voluntariness and
Informed Choice
Not only does valid consent
require that the individual be competent and informed,
it also requires that the choice to participate be made
freely and voluntarily. In order for consent to be voluntary,
free, and genuine, an individual must have the opportunity
to choose between consent and refusal without undue interference,
fear, constraint, compulsion, or undue inducement.
While situations of physical
duress or of fraudulent misrepresentation of facts are
universally recognized as inappropriate, control may be
exerted by more subtle means. Undue influence may take
the guise of: promises of companionship, love, or affection;
economic incentives; emphasis on benefits over risks or
burdens; or, appeals to emotional weaknesses, loyalty
to professional caregivers, or family solidarity.
Researchers must pay special
attention to assessment of voluntariness in the following
situations.
Table
of Contents
Many prospective research participants
live in situations of increased dependence on family and
other caregivers. Such situations should raise sensitivity
to the voluntariness of a prospective research participant's
consent; careful scrutiny is required to assure its authenticity.
Undue influence placed on an individual by family, friends,
health care professionals, or anyone else should be avoided.
At the same time, it is important to recognize diverse
decision-making processes in different families and cultures.
For example, some prospective participants will prefer
full discussion with other family members before making
a choice whether to participate, while others will not.
Table
of Contents
| B.
Long Term and Chronic Care |
Individuals in long-term care
facilities are particularly vulnerable due to their level
of dependence, especially on health care professionals,
for fulfilment of basic daily physical, social, and even
emotional needs. This extreme dependence frequently encourages
passivity and a willingness to comply with instructions,
even on the part of those who are mentally competent.
Increased levels of vulnerability also occur in persons
who live outside institutions, but who depend heavily
upon health care establishments for chronic or long-term
care. Such individuals should never be made to feel obliged
to participate in projects for fear that their current
or future care or the esteem of their caregivers may depend
upon participation.
Researchers must detail their
recruitment plans when approaching such individuals for
participation in research protocols.
Table
of Contents
| C.
Incentives to Participate in Research |
Payments and other inappropriate
incentives offered for the purpose of inducing participation
on the part of those who would not otherwise participate
in a protocol unduly affect freedom of choice and are
unacceptable. Payment made for any inconvenience to a
participant, or for services that are rendered at a rate
which is appropriate (attractive but not inducing) is
acceptable. Repayment to research participants or their
substitute decision-makers for out-of-pocket expenses
such as babysitting, transportation, or meals is appropriate.
Non-financial incentives such
as promises of modification of care, or early placement
in long-term care facilities, constitute undue influence
when dealing with either or both the prospective research
participant and her or his substitute decision-maker.
Finally, since a strong motivation
for participating may be the offer of treatment, disclosure
of a placebo research design must be made in the clearest
possible terms.

the upper right-hand corner of each page. This
should be the date of REB approval of the protocol. The
objective is to ensure that any subsequent amended version
of the research consent form can be easily identified.
For example, it is possible that new information regarding
the potential harms and benefits of research might require
a revision to the original research consent form. It follows
that the date of any revision after the original approval
should be placed in the upper right-hand corner.
Title of the Research
The research consent form should
include the exact title of the research protocol (i.e.,
the title under which the research was approved and funded).
When the title is particularly cumbersome, a short simplified
title may be added.
Researcher(s)
The name(s), degree(s), department
(and affiliation, if other than the institution where
the research is being conducted), and contact telephone
number(s) of all researchers should appear immediately
below the title of the research project.
Care must be taken not to mislead
or misrepresent facts. For example, if a researcher is
a student, this must be explicitly stated and the name(s),
degree(s), department (and affiliation, if other than
the institution where the research is being conducted),
and telephone number(s) of the supervisor must also appear
on the form.
A prospective research participant
might also be misled if it is not clear that Dr. Smith
(M.D.) is a physician, while Dr. Jones (Ph.D.) is not.
The difference and its relevant implications must be made
clear.
Also, it is imperative that
the contact person (usually the principal researcher)
be explicitly identified and an invitation offered to
the prospective research participant to call with any
questions. Time of availability should be clearly indicated
(e.g., Monday to Friday, 9:00 to 5:00).
Sponsor(s)
The name of the company(ies)
and/or the granting agency(ies) that is (are) sponsoring
the research must appear on the form. As well, it is appropriate
to indicate if the research is being done at a single
site or whether the research is part of a multi-centre
trial.
Purpose of the Research
A brief description of the
purpose of the research should explain what hypothesis
is being tested and what the research is supposed to demonstrate.
If there are specific inclusion and exclusion criteria
for research participation, these should be noted here.
Description of the Research
A step-by-step description
of the research as it will be experienced by the research
participant must be provided, and it must clearly explain
the expected length of her or his participation in the
research. The objective is to provide the prospective
research participant with a clear understanding of how
she or he will be involved in the research (e.g., completion
of a questionnaire, studies in behaviour modification,
testing of equipment, testing of a new drug, or surgical
intervention). In providing this description it is important
to explain:
- whether any specific testing
is required to determine eligibility for research participation
(e.g., HIV testing, psychological testing);
- whether the research design
involves specific research techniques such as randomization,
sequential assignment, blinding, or placebo control;
- whether the person's health
record will be reviewed;
- whether radiation is involved
and, if so, the level of radiation to which the participant
will be exposed;
- whether blood testing is
involved and, if so, the amount of blood that will be
taken;
- whether research participation
will result in missed school or work;
- whether future use of the
research data (e.g., subsequent use of photographs,
videos, sound recordings, DNA information, permanent
cell lines) is or is not anticipated. If future use
of the data/samples is anticipated, this must be explained
and the prospective participant must be assured that
the data/samples will be maintained in a manner that
ensures confidentiality. If future use of the data/
samples is not anticipated, the participant should be
told that the data/samples will be destroyed once the
research is complete;
- rules for stopping the research
and/or removing a participant from the research.
As well, if the prospective
research participants are patients, it is important to
explain:
- which interventions are
part of standard therapy and which interventions are
purely research;
- whether any therapy that
is being received will be altered or discontinued as
a result of research participation;
- whether research participation
will require additional visits to the hospital or lengthen
hospital stay;
- whether the service/drug/intervention/device
will or will not be available to the participant once
the research is complete, assuming that the service/drug/
intervention/device was found to be beneficial. (It
is expected that, where appropriate, the researcher
will attempt to secure agreement from the sponsor to
continue to provide the service/drug/intervention/device
to research participants beyond the original research
time frame, until it is available in a therapeutic context).
Potential Harms
Potential harms and potential
benefits of research must be described separately from
one another. Moreover, to further the goal of voluntariness,
potential harms must be listed prior to potential benefits.
If there are no known or anticipated
harms associated with the proposed research, this should
be stated explicitly. If there are known potential harms
to the research participant, these should be described
as accurately as possible. This description should include
relevant information about the nature of the potential
harm(s) (how serious is the potential harm?), and the
probability of occurrence (how likely is it that the potential
harm will occur?). As well, information concerning the
possibility of reversibility should be included along
with a description of any precautions that will be taken
to minimize the probability of occurrence. In either case,
there should be a statement acknowledging the possibility
of unforeseen harms.
Potential Benefits
If there are no potential benefits
to the prospective research participant, this must be
stated explicitly. If there are potential benefits to
the participant, these should be described as accurately
as possible. This description should include relevant
information about the nature of the potential benefit(s)
(how important are these benefits?) and the probability
of occurrence (how likely is it that the potential benefits
will occur?).
In research projects where
there may be anticipated benefits to society or to a specific
group within society (e.g., persons with a particular
disease/disorder), these potential benefits must be explained
in a separate paragraph so as not to confuse potential
benefits to others wa particular disease/disorder), these
potential benefits must be explained in a separate paragraph
so as not to confuse potential benefits to others with
potential benefits to the research participant.
Alternatives
If the research does not include
patients as research participants, this section may be
deleted. If the prospective research participant is not
a patient, the alternative to research participation is
non-participation and this is explained under the subheading
"participation".
If the research does include
patients as participants, it is important that the prospective
research participant know whether there are any "treatment"
alternatives. If there are no such alternatives (i.e.,
no available therapy), this should be stated. If there
are treatment alternatives, the alternatives should be
described and this description should include a summary
of the nature of the alternative intervention(s), as well
as the potential harms and benefits.
Confidentiality
It is important for the prospective
research participant to know who will have access to the
research data/samples, and how such data/samples will
be stored.
Usually, it is possible to
assure the prospective research participant that confidentiality
will be respected and that no information that discloses
the participant's identity will be released or published
without the proper consent. It is important to note, however,
that certain agencies may legitimately require access
to research files to monitor ongoing research. When applicable,
this should be explained in the research consent form
and the name(s) of the agency(ies) to whom identifying
information will be available should be provided (e.g.,
the research sponsor, Health Protection Branch, the U.S.
Food and Drug Administration).
When there are separate plans
to use identifying information (e.g., the use of photographs,
videos, or sound recordings) for subsequent research or
for teaching purposes, this must be disclosed in the research
consent form and there should be a separate consent form
for the subsequent use of the identifying information.
In most cases, this separate consent form should only
be presented to the prospective research participant once
she or he has had an opportunity to review the identifying
information and, on this basis, to decide whether to consent
or refuse to allow the data to be used for future research
or teaching.
As a separate matter, the research
consent form should explain that if the participant is
a patient in the institution where the research is being
conducted, information regarding her or his participation
will be added to her or his health record. At the very
least, the signed research consent form will be part of
the health record. As well, test results (e.g., HIV test,
genetic tests) and other research findings (particularly
when these may directly impact on treatment) may be included
in the health record. If this is the intention or a likely
consequence of the research, it must be disclosed.
Finally, in rare instances
it will not be possible to ensure confidentiality (e.g.,
suspected child abuse, reportable communicable diseases).
When this is the case, the prospective research participant
should be aware of this limitation.
Reimbursement
When reimbursement is available
for lost wages (minimum wage) and out-of-pocket expenses
(transportation costs, meals, baby-sitters, etc.), this
should be disclosed in the research consent form. As well,
it should be explained that a decision to withdraw from
the research will not affect any reimbursement costs that
may have been incurred prior to withdrawal.
Participation
The prospective research participant
must be told very explicitly that she or he has the right
to refuse to participate in the proposed research and,
moreover, that a decision to participate in the research
is not binding. It is important to make it clear that
participant withdrawal may be made at any time without
negative consequences.
In those rare instances where
it will not be possible for the participant to withdraw
from the research, this should be explained (e.g., research
on somatic cell gene transfer). It is equally important
to advise participants that withdrawal of their participation
does not necessarily include withdrawal of any data compiled
up to that point.
Finally, this section should
include an offer to share the research findings with the
participant upon completion of the research.
Publication
The investigator must:
- undertake to alert the participant
to publication of results; and
- tell the participant that
such publication will not reveal the identity of the
participant.
Consent
This section should provide
a brief (one paragraph) summary of the research stating
that the potential harms, benefits, and alternatives have
been explained. There should be a statement to the effect
that the prospective research participant:
- has read and understood
the relevant information;
- understands that she or
he may ask questions in the future;
- indicates free consent to
research participation by signing the research consent
form.
When consent is provided by
a substitute decision-maker, there should be a record
of the prospective research participant's assent to research
participation, provided the prospective participant is
capable of assent (e.g., this is possible for older children
but not for comatose patients). The research participant's
assent should be indicated on the form by the researcher
who obtained the consent from the substitute decision-maker,
not by having the participant sign the form.
The participant's (or substitute
decision-maker's) signature should be followed by a signed
statement from the researcher who obtained the consent.
This statement should indicate that she or he explained
the research to the prospective participant or substitute
decision-maker and, that to the best of her or his knowledge,
the prospective participant or substitute decision-maker
understood the proposed research and freely consented
to research participation.
Warning
The research consent form should
not include any reference to a waiver by the participant
of any of the participant's legal rights. The participant
should not be asked to release the researcher, the sponsor,
or the institution where the research is being conducted,
from liability or negligence.
Suggested Wording
Potential Harms
"There are no known harms
associated with your participation in this research. However,
there may be harms that we don't yet know about."
Potential Benefits
"There are no known benefits
to you associated with your participation in this research."
"You will not benefit directly from participation
in this research."
Confidentiality
"Confidentiality will
be respected. No information that discloses your identity
will be released or published without your specific consent
to the disclosure."
"Confidentiality will
be respected. No information that discloses your identity
will be released or published without your specific consent
to the disclosure. However, it is important to note that
the original signed research consent (and the data which
will follow), will be included in your health record."
"Confidentiality will
be respected. No information that discloses your identity
will be released or published without your specific consent
to the disclosure. However, it is important to note that
the original signed research consent (and the data which
will follow), will be included in your health record.
As well, research records identifying you may be inspected
by representatives of (at this point name the sponsoring
company, the Health Protection Branch, and the U.S. Food
and Drug Administration, etc.) for the purpose of monitoring
the research."
But
"If we find information
we are required by law to disclose (e.g., child abuse,
inability to hold a valid driver's licence, etc.), we
cannot guarantee confidentiality."
Participation
"Participation in research
must be voluntary. If you choose not to participate, you
and your family will continue to have access to quality
care. If you choose to participate and later decide to
change your mind, you can say no and stop the research
at any time. Again, you and your family will continue
to have access to quality care."

Research
Information Form: For Prospective Research Participants
who May be Deemed Competent to Assent or Dissent to
Research Participation |
This form can be used along
with the Research Consent Form but not without it.
The following format should
be used:
- Title of the Research
- Researcher
- Why are we doing this
research?
- What will happen during
the research?
- Are there good things
and bad things about the research?
- Who will know about what
I did in the research?
- Can I decide if I want
to be in the research?
The substance of the content
listed under these headings should be the same as for
the analogous headings outlined for the Annotated Research
Consent Form. The information form is meant to be
understood by a child seven years of age. Wording should
be kept very simple. Sentences should use the active voice
at all times. Restrictive clauses should be avoided.

Sample Consent Form Checklist |
This checklist is designed to
assist researchers in drafting, and REB members in reviewing,
research consent forms. The checklist enumerates elements
that should be included in the research consent form.
Carefully review the draft consent form and check each
element that is present.
The consent form clearly identifies:
 |
the
researcher(s), and if the researcher(s) is/are a student(s),
the supervisor(s) (the person who is available to
answer pertinent questions should be clearly identified);
|
 |
the
sponsor(s) of the research. |
The consent form clearly explains:
 |
that
the proposed intervention is for research
(drug, device, procedure, etc., used for research
purposes); |
 |
the
purpose of the proposed research
(why the research is being done); |
 |
the
nature of the proposed research
(what the research involves; this should include details
re: the use of a placebo: the nature of the randomization;
the need to discontinue standard therapy); |
 |
the
likely duration of participation
(how long the research and each intervention will
take): |
 |
the
potential harms and inconveniences associated with
the research
(the nature of the harms and inconveniences and the
likelihood of their occurrence); |
|
