4
Informed Consent Research and data on Informed Consent Used in 84 countries It is a process, not a form Elements of Informed Consent Disclosure of information Understanding Voluntariness Consent authorization
5
Disclosure – Required Elements Statement of Research Purpose and procedures Foreseeable risks and discomforts Any benefits to subjects and others Appropriate alternatives Extent of Confidentiality Treatment or compensation for injury Who to contact for answers to questions Participation is voluntary
6
Considerations About Presentation of Information 1. Reading level should be understandable to research subjects 2. Formatting-Headings? White Space? 3. Content-basic elements included? 4. Length-can document be shortened without compromising clarity or other requirements?
7
Data on Disclosure Content documents Readability (studies show reading levels are typically too high and forms are too long.) Should be 8 th grade level. Content: only 3/16 consent forms had all required elements Discussion Content: some say consent forms are for researcher and are not really read by participant. Quality of interaction: a study showed this method had higher level of completeness in video format than f2f meeting. Assessment of understanding is rarely done.
8
Factors that Affect Understanding Age Severity of illness Educational Level Cognitive capacity Familiarity with research Language and customs Literacy Variable Data that affect understanding College education - speaking only English at home Education and age Research Experience
9
Placebo Often, participants do not understand that they might be receiving a placebo 10 % of Gambian mothers understood placebo design of vaccine trial 67% of US participants in rheumatoid arthritis trial knew some people would get a placebo.
10
How to Measure Voluntariness Did individuals choose not to participate? Did participants feel pressure to join? Did participants know that they could refuse or withdraw? Data shows that few people opt out of studies. About half knew they could quit.
11
How to Improve Consent Multimedia (e.g. audiotapes, videotapes, interactive computers) Enhanced consent form (e.g. modified style, format or length. Extended discussion (with team member or neutral educator) Test/feedback (e.g. quizzes and review) More person to person contact
12
Conclusions Consent forms are long and complex Understanding is variable and especially lacking in certain areas (randomization) Many participants do not know/feel they can quit Spending more time may enhance understanding
