What is an Informed Consent Form?
An informed consent form is a document explaining research study details and obtaining voluntary agreement from participants. It ensures participants understand what research involves, what they'll be asked to do, potential risks and benefits, and their rights. Informed consent is both an ethical requirement and legal protection for researchers and institutions.
Required Elements
Federal regulations and IRBs require consent forms to include:
- Study purpose and procedures - What research investigates and what participants will do
- Duration - How long participation takes
- Risks and discomforts - Potential harms or inconveniences
- Benefits - Potential advantages to participants or society
- Alternatives - Other options available to participants
- Confidentiality - How privacy and data security are protected
- Voluntary participation - Right to decline or withdraw without penalty
- Contact information - Researchers and IRB contacts for questions
- Compensation - Payment or incentives offered
- Consent statement - Participant signature indicating agreement
Why Proper Consent Matters
Ethical Imperative
Respect for persons requires that individuals make autonomous, informed decisions about research participation. Consent forms facilitate this autonomy by providing information needed for meaningful choice. Without proper consent, research violates fundamental ethical principles.
Legal Protection
Documented informed consent protects researchers, institutions, and participants. If participants claim they weren't informed about risks or procedures, signed consent forms demonstrate that information was provided and understood. This documentation is crucial if legal issues arise.
IRB Requirements
Institutional Review Boards won't approve research without acceptable consent forms. IRBs review forms carefully, often requiring multiple revisions before approval. Starting with well-structured forms expedites approval processes.
Participant Trust
Clear, honest consent forms build participant trust. When participants understand exactly what they're agreeing to, they're more likely to complete studies and provide high-quality data. Unclear or deceptive consent undermines trust and data quality.
Consent Form Sections
Study Title and Introduction
Begin with study title and brief introduction:
- Clear, descriptive study title
- Primary investigator name and affiliation
- Funding source (if applicable)
- Invitation to participate
Example: "You are invited to participate in a research study examining factors influencing graduate student wellbeing. This study is conducted by Dr. Jane Smith at University Name and funded by the National Science Foundation."
Purpose Statement
Explain why research is being conducted:
- Research problem or question
- Study goals and objectives
- Why this research matters
- Expected contribution to knowledge
Write at 8th grade reading level. Avoid jargon. If technical terms are necessary, define them clearly.
Procedures Description
Detail exactly what participants will do:
- Number and duration of sessions
- Activities or tasks involved
- Data collection methods (surveys, interviews, observations)
- Location where participation occurs
- Timeline and scheduling
Be specific: "You will complete three 60-minute interviews over 6 months. Interviews will be audio recorded and occur at a location convenient for you."
Risks and Discomforts
Honestly describe potential risks:
- Physical risks - Pain, injury, fatigue
- Psychological risks - Anxiety, emotional distress, triggering
- Social risks - Stigma, discrimination, relationship impacts
- Economic risks - Time, transportation costs, lost wages
- Legal risks - Disclosure of illegal activities
Also acknowledge minimal risk: "This study involves no risks beyond those encountered in daily life." Honesty about risks demonstrates respect and allows informed decision-making.
Benefits
Describe potential benefits realistically:
- Direct benefits - Potential personal advantages
- Societal benefits - How research may help others or advance knowledge
- No benefit statement - If no direct benefit: "You may not personally benefit from this study, but your participation will contribute to understanding..."
Don't overstate benefits. IRBs reject forms promising unrealistic outcomes.
Confidentiality Protections
Explain how privacy will be protected:
- Data storage - Where and how data are secured
- Access limits - Who can view identified data
- Identifiers - Whether data will be de-identified
- Reporting - How results will be presented without revealing identities
- Limits to confidentiality - Legal requirements to report (child abuse, imminent harm)
Example: "Your responses will be kept confidential. Data will be stored on password-protected computers. Only the research team will access identified data. Publications will use pseudonyms protecting your identity."
Voluntary Participation
Emphasize freedom to decline or withdraw:
- Participation is completely voluntary
- Right to refuse without penalty
- Right to withdraw at any time without consequence
- No impact on services, grades, employment, or care
- What happens to data if participant withdraws
Example: "Your participation is entirely voluntary. You may decline to participate or withdraw at any time without affecting your relationship with the university or the services you receive."
Compensation
If offering payment or incentives:
- Amount and form of compensation
- Payment schedule (partial for incomplete participation or only if completed)
- Tax implications if applicable
- Retained compensation if participant withdraws
Example: "You will receive a $20 gift card after completing the interview, regardless of whether you answer all questions."
Contact Information
Provide contacts for questions:
- Researcher contact - Primary investigator name, phone, email
- IRB contact - IRB office name, phone, email for questions about rights
- Additional contacts - Co-investigators, supervisors, department chairs
Signature Block
Include signature lines for:
- Participant signature and date
- Researcher signature and date
- Witness signature (if required by IRB)
- Optional: Participant's printed name for legibility
Special Populations
Children (Minors)
Research with children requires parental consent plus child assent. Create separate assent forms using age-appropriate language. Younger children may provide verbal assent; older children sign assent forms.
Cognitively Impaired Participants
Individuals with cognitive impairments may lack capacity to consent. Legal guardians provide consent, but participants should still provide assent when possible. IRBs carefully scrutinize research with vulnerable populations.
Non-English Speakers
Provide consent forms in participants' primary languages. Professional translation services are essential - family members or research assistants shouldn't translate consent documents. IRBs require certified translations.
Consent Process
Form Distribution
Provide consent forms before participation, allowing time for review. For interviews, email forms several days in advance. For surveys, present consent before questions begin. Don't rush consent - allow questions and reflection.
Discussion and Questions
Researchers should review forms with participants, inviting questions. Simply handing someone a form to sign doesn't constitute informed consent. Engagement and understanding matter, not just signatures.
Documentation
Keep signed consent forms securely, separate from de-identified data. Consent documents often represent the only link between participant identities and data, so they require highest security.
