Some influences on public participation in a genetic screening program
Journal of Community Health
|January 1, 1975
Summary
Younger, better-educated individuals with higher perceived susceptibility are more likely to participate in voluntary genetic testing for Tay-Sachs disease. They also report lower perceived impact and are less likely to alter future family planning.
Area of Science:
- Genetics
- Public Health
- Behavioral Science
Background:
- Mass genetic testing programs require understanding participant motivations.
- Voluntary cooperation is crucial for the success of genetic screening initiatives.
- Identifying psychosocial factors can improve recruitment for genetic testing.
Purpose of the Study:
- To determine psychosocial factors influencing voluntary participation in mass genetic testing.
- To compare characteristics of participants and non-participants in Tay-Sachs disease screening.
- To inform strategies for enhancing future genetic screening program engagement.
Main Methods:
- Stratified random sampling of 500 participants and 500 non-participants from an at-risk population.
- Comparative analysis of demographic and psychosocial characteristics.
- Focus on Tay-Sachs disease genetic testing.
Main Results:
- Participants were younger and more educated than non-participants.
- Higher perceived susceptibility to being a carrier was associated with participation.
- Participants reported lower perceived impact of carrier status and less intention to alter future progeny plans.
Conclusions:
- Psychosocial factors like perceived susceptibility and impact significantly influence genetic testing participation.
- Targeting younger, educated individuals with tailored messaging may increase engagement.
- Recommendations for enhancing participation in genetic screening programs are provided.
