The purpose of this study is to identify individual-level characteristics of foster care adolescents who are more likely to not participate in, and drop out of, a life-skills HIV prevention program delivered over 8 months. Structured interviews were conducted with 320 foster care adolescents (15-18 years). Logistic regression and survival analyses (Cox Proportional Hazards Regression) determined the influence of demographics, HIV sexual risk behaviors, substance use, mental health problems, and other individual-level risk factors on nonparticipation and dropout. Older age and having vaginal intercourse without a condom were significant predictors of nonparticipation. Older age and marijuana use significantly increased the hazard of dropping out of the program. Foster care adolescents at increased risk for HIV infection were more likely to never participate in and drop out of the program. To improve initial and ongoing participation, HIV prevention efforts for adolescents in foster care should be tailored to individual-level HIV risk behaviors and incorporate early and ongoing engagement and retention strategies.
本研究的目的是确定寄养青少年个体层面的特征，这些特征更有可能导致他们不参与一项为期8个月的生活技能艾滋病毒预防计划，并从该计划中退出。对320名寄养青少年（15至18岁）进行了结构化访谈。逻辑回归和生存分析（Cox比例风险回归）确定了人口统计学、艾滋病毒性风险行为、物质使用、心理健康问题以及其他个体层面风险因素对不参与和退出的影响。年龄较大以及无保护措施的阴道性交是不参与的显著预测因素。年龄较大以及使用大麻显著增加了退出该计划的风险。感染艾滋病毒风险增加的寄养青少年更有可能从不参与该计划并退出。为了提高初始参与度和持续参与度，针对寄养青少年的艾滋病毒预防工作应根据个体层面的艾滋病毒风险行为进行调整，并纳入早期和持续的参与及留存策略。
