Study Objective
To understand adolescents’ and parents’ willingness to participate (WTP) in a hypothetical Phase I prevention study of sexually transmitted infections, discordance within adolescent-parent dyads, and expectations of each other during decision-making.
Design
Adolescent-parent dyads were recruited to participate in a longitudinal study about research participation attitudes.
Participants
Adolescents (14–17 years old) and their parents (n=301 dyads) participated.
Interventions
None
Main outcome measures
Individual interviews at baseline assessed WTP on a six-level Likert scale. WTP was dichotomized (willing/unwilling) to assess discordance.
Results
WTP was reported by 60% of adolescents and 52% of parents. In bivariate analyses, older adolescent age, sexual experience and less involvement of parents in research processes were associated with higher level of WTP for adolescents; only sexual experience remained in the multivariable analysis. For parents, older adolescent age, perceived adolescent sexual experience, and conversations about sexual health were significant; only conversations remained. Dyadic discordance (44%) was more likely in dyads where the parent reported previous research experience, and less likely when parents reported higher family expressiveness. Adolescents (83%) and parents (88%) thought that the other would have similar views, influence their decision (adolescents 66%, parents 75%), and listen (adolescents 90%, parents 96%). There were no relationships between these perceptions and discordance.
Conclusions
Inclusion of adolescents in Phase 1 clinical trials is necessary to ensure that new methods are safe, effective and acceptable for them. Given that these trials currently require parental consent, strategies that manage adolescent-parent discordance and support adolescent independence and parental guidance are critically needed.
