Abstract/OtherAbstract:
Depressed adolescents are more likely to engage in sexual risk behaviors than their non-depressed peers. The objectives of this study were (1) to examine whether affective states predicted subsequent condom use, directly or indirectly through contextual factors and (2) to compare results obtained from structural equation models versus non-linear mixed effects models. This study used ecological momentary assessment to collect data on in-the-moment affective states and sexual behavior from 51 depressed adolescents (7 male, 44 female) aged 15-22 years. The association between positive and negative affect and condom use during a subsequent sex event was explored using several structural equation models and non-linear mixed effects models. Potential mediation by substance use before sex, partner type, reason for sex, and who wanted sex was examined. Neither positive nor negative affect was directly associated with condom use in any models; however, negative affect was associated with increased likelihood of sex with a non-main partner, which, in turn, was associated with increased condom use. Both structural equation models and non-linear mixed effects models successfully modeled the relationship between affect and condom use in momentary data while correctly accounting for the correlation of multiple observations from the same individual. The benefit of structural equation modeling was the ability to directly model the mediation of this effect by contextual factors. In this sample of depressed adolescents, negative and positive affect did not appear to be directly predictive of condom use during a subsequent sex event, although may indirectly affect condom use through sex with a non-main partner.
