Methods: The Youth Health Risk Behavioral Inventory was administered to a sample of 267 American Indian, reservation-based adolescents ages 13-19, as a part of a randomized controlled trial of an adapted evidence-based HIV prevention intervention. Exploring baseline data, multivariate analyses were conducted to understand how PMT constructs predict condom use intention among boys and girls as well as younger (13-15) and older (16-19) adolescents.
Results: Results indicate significant differences in theoretical predictors of condom use intention across groups. Among boys, significant PMT constructs predictive of condom use intention were response efficacy, extrinsic rewards and severity. Only intrinsic rewards and response cost were more likely to predict condom use intention among girls compared to boys. Across age groups, self-efficacy, response efficacy, extrinsic rewards and severity predicted condom use intention among younger adolescents while only response efficacy predicted condom use intention among older participants.
Conclusions: Similar to other studies, there were significant differences in predictors of condom use intention across age and sex. Prevention interventions should target theoretical constructs predictive of condom use intention and be tailored to specific sex and age differences among AI adolescents. Among AI girls, intervention efforts should focus on identifying healthy activities that are internally rewarding. For boys, interventions should focus on the peer acceptance of condom use and emphasize the efficacy of condoms. Regarding different age groups, among young AI adolescents interventions focused on self-efficacy and severity would be more effective than they would be among older AI teens. Although most current prevention interventions include adolescents spanning wide age ranges and both sexes, our results indicate sex and age-specific interventions may be a more effective prevention approach.
