Funding Acknowledgments • National Institutes of Mental Health • F31MH082646-01A2 (PI E.Volpe, Sponsor: D. Morrison-Beedy) • National Institutes of Nursing Research • T32NR007100, (PI M. Sommers) • Sigma Theta Tau, Epsilon Chapter • Susan B. Anthony Institute
Background • Adolescent girls with older male partners at increased risk for HIV/STIs (e.g. Seth et al., 2010, Ryan et al., 2008, Senn et al., 2011) • Relationship power assumed to be the theoretical link between older partners and sexual risk behaviors (e.g. DiClemente et al., 2002; Teitelmanet al., 2011) • Intimate Partner Violence (IPV) has been linked to sexual risk behavior ( e.g. Halpern et al., 2009, Howard et al., 2007, Seth et al. 2010)
Access to and use of sexual & reproductive services Individuals’ social and economic characteristics Demographic characteristics Family/household characteristics Community characteristics Reproductive health domains: Consistent Condom Use Gender-based power in sexual relationships Violence: Physical IPV/ Psychological IPV Partner Age Difference as a Predictor of Relationship Power, IPV, and Consistent Condom use in Adolescent Girls • Relationship characteristics: • Partner Age Difference
Specific Aims • Examine the proposed model: Partner Age Difference as a Predictor of Relationship Power, IPV, and Consistent Condom usein Adolescent Girls • Estimate the direct effects of partner age difference on consistent condom • Analyze the indirect effects of that relationship through proposed mediators, relationship power and IPV
Methods • Design • Cross-sectional, descriptive survey • Setting • School-based health center, mid-size city • Sample • 155 sexually-active, low-income adolescent girls (ages 14-18) in reported “boyfriend” relationship • Procedures • Anonymous, computer assisted self-interview (CASI): Promote Health
Methods: Measures • Partner age difference • Sexual Relationship Power Scale (Pulerwitz et al., 2002) • Relationship Power • Decision-making Dominance • Conflict Tactics Scale (Straus & Douglas, 2004) • Severity of physical and psychological IPV • Consistent condom use
Methods: Analyses • Descriptives • Bivariate correlations • Multiple mediation models to estimate direct and indirect effects (Preacher & Hayes, 2008)
Results: Condom Use • Average of 24.5 episodes of vaginal sex, and 7.9 episodes of unprotected sex in 3 months • Only 24% of adolescent girls reported consistent condom use
Results: Relationship Power • An average of 2.9 on relationship power scale (1-4) • Almost 2/3rds fell into high relationship power level • Relationship control inversely correlated with IPV severity • Decision-making Dominance positively correlated with consistent condom use
Results: IPV • Adolescent girls reported high frequency of victimization • Physical: 18% minor only, 18% severe • Psychological: 47% minor only; 35% severe

Discussion • Partner age difference was negatively correlated with consistent condom use • Not explained by any of the proposed mediators: relationship power, severity of physical and psychological IPV • Alternative explanations: • Emotional manipulation not identified in relationship power • Clustering of adolescent risk behavior • Complexity of condom use decision-making in relationships
Discussion • Prevalence of physical and psychological IPV severity • Discreet constructions of relationship power • Relationship control: inversely related to IPV • Decision-making dominance: consistent condom use
Limitations • Cross-sectional design • Lack of variability in partner age difference • Lack of context for violence or measure of sexual risk
Implications • Elucidate the degree of partner age difference that predicts low relationship power • Investigate alternative explanations to explain partner age difference’s relationship to condom use • Examine implications of high relationship power among adolescent girls • Incorporate partner age, relationship control, and decision-making dominance in interventions
