Item Change in Age-Specific, Psychosocial Correlates of Risky Sexual Behaviors Among Youth: Longitudinal Findings From a Deep South, High-Risk Sample(Springer, 2014) Ritchwood, Tiarney D.; Howell, Rebecca J.; Traylor, Amy C.; Church, Wesley T., II; Bolland, John M.; University of North Carolina; University of North Carolina Chapel Hill; University of Alabama TuscaloosaThe current study examined psychosocial predictors of change in intercourse frequency and number of sexual partners among youth within a socio-ecological framework and assessed whether these determinants vary by stage of adolescent development. Longitudinal data were derived from a large, community study of adolescent risky behavior among predominantly high-risk, African American youth. Significant predictors of intercourse frequency for early adolescents included age, gender, self-worth, and familial factors; for older youth, age, gender, self-worth, curfews, and sense of community exerted significant effects. Among early adolescents, age, gender, self-worth, familial factors, and sense of community predicted change in the number of sexual partners in the previous year, while age, gender, self-worth, parental knowledge, curfews, and sense of community were predictive of change in the number of sexual partners in the previous year among older youth. Study implications and future directions are discussed.Item Does it really matter which drug you choose? An examination of the influence of type of drug on type of risky sexual behavior(Pergamon, 2016) Ritchwood, Tiarney D.; DeCoster, Jamie; Metzger, Isha W.; Bolland, John M.; Danielson, Carla K.; Medical University of South Carolina; University of Virginia; University of Alabama TuscaloosaThis study investigates whether certain types of substances are differentially related to certain risky sexual behaviors (RSBs) within the same population and determines whether combination substance use (SU) has additive, redundant or antagonistic effects on RSBs. African-American youth aged 9-19 participated in a large, community-based survey assessing substance use and sexual behaviors. Multilevel modeling was used to predict the differential influence of alcohol, marijuana, and cocaine use on condom use measured in the past 90 days and at last intercourse, sex while drunk/high, and number of sexual partners. Tests of the within-participant relations showed that participants increasing their SU over time concurrently increased their RSBs, establishing a strong link between the two behaviors (alcohol: condom beta = 0.045, sex while drunk/high beta = 0.138, sex partners beta = 0.102; marijuana: condom beta = - 0.081, sex while drunk/high beta = 0.255, sex partners beta = 0.166; cocaine: condom beta = - 0.091, sex while drunk/high beta = 0.103, sex partners beta = 0.031; all p's < 0.01). Tests of the between-participant relations showed that, generally, youth reporting less SU across their teenage years were also more likely to report fewer RSBs over this period (alcohol: condom beta = - 0.128, sex while drunk/high beta = 0.120, sex partners beta = 0.169; marijuana: condom beta = - 0.170, sex while drunk/high beta = 0.638, sex partners beta = 0357; cocaine: condom beta = - 0353; all p's < 0.05). Moreover, the combination of some substances has unique redundant or antagonistic effects on RSB. Such findings support the consideration of type of SU, and particular combinations of substances, on RSBs in intervention development. (C) 2016 Elsevier Ltd. All rights reserved.
