Data are lacking on long-term effects of HIV behavioural intervention programmes. In this study, we report intervention effects 36 months postintervention on condom use and relevant outcome variables from the theory-based programme 'Focus on Youth in the Caribbean' (FOYC). Participants (1360 sixth-grade youth) were randomized by school into: (1) FOYC, plus one of two brief parent interventions or (2) the control condition 'Wondrous Wetlands', plus a brief parent intervention. Mixed effect analysis demonstrated significant programme effects, including enhanced HIV/AIDS knowledge (effect size D = 0.44, 95% confidence interval [CI]: 0.43, 0.46), increased self-efficacy of (D = 0.42, 95% CI: 0.30, 0.54), skills for (D = 0.62, 95% CI: 0.56, 0.64) and intention to use a condom (D = 0.20, 95% CI: 0.03, 0.37). Youth who received FOYC plus the parental monitoring intervention had higher condom use rates (odds ratio = 1.49, 95% CI: 0.97, 2.28). Feedback effects from key variables were also detected, supporting the sustained effect.
关于艾滋病病毒行为干预项目的长期影响，目前缺乏相关数据。在本研究中，我们报告了基于理论的项目“关注加勒比地区青少年”（FOYC）干预36个月后对避孕套使用及相关结果变量的干预效果。参与者（1360名六年级青少年）按学校随机分为：（1）FOYC组，加上两种简短家长干预措施中的一种；或（2）对照条件“奇妙湿地”组，加上一种简短家长干预措施。混合效应分析显示出显著的项目效果，包括艾滋病病毒/艾滋病知识增强（效应量D = 0.44，95%置信区间[CI]：0.43，0.46）、自我效能感提高（D = 0.42，95% CI：0.30，0.54）、相关技能提升（D = 0.62，95% CI：0.56，0.64）以及使用避孕套的意愿增强（D = 0.20，95% CI：0.03，0.37）。接受FOYC加上家长监督干预措施的青少年避孕套使用率更高（优势比 = 1.49，95% CI：0.97，2.28）。还检测到关键变量的反馈效应，支持了持续效果。
