The spread of human immunodeficiency virus infection to impaired groups has intensified the challenge for its prevention; control of the epidemic now requires behavioral change among persons with limited ability to sustain attention and learn. In this randomized clinical trial, we tested an intervention to reduce sexual risk behaviors among homeless men with severe mental illness.
Men were recruited from a psychiatric program in a homeless shelter. Of 116 eligible men, 97 (83.6%) participated. Most were African American and had a chronic psychotic disorder and a comorbid substance use disorder. Participants were assigned to a 15-session experimental group intervention or to a 2-session control intervention and observed for 18 months. The 59 participants sexually active before the trial were the main target of the intervention. Sexual risk behavior was the primary outcome.
Among the 59 sexually active men, follow-up data were obtained on 59 (100%) for the initial 6-month follow-up and on 56 (95%) for the remainder of the 18-month follow-up. The mean score on a sexual risk index for the experimental group was 3 times lower than for the control group (1.0 vs 3.1; P=.01) during the initial 6-month follow-up and 2 times lower during the remainder of the 18-month follow-up.
This intervention successfully reduced sexual risk behaviors of homeless men with mental illness. The effect diminished over 18 months but did not disappear. Similar approaches may be effective in other impaired high-risk groups.
人类免疫缺陷病毒感染向弱势群体的传播加剧了预防工作的挑战;当前控制该流行病需要注意力持续能力和学习能力有限的人群改变行为。在这项随机临床试验中,我们测试了一种干预措施,以减少患有严重精神疾病的无家可归男性的性风险行为。
从一家无家可归者收容所的精神科项目中招募男性。116名符合条件的男性中,97名(83.6%)参与。大多数为非裔美国人,患有慢性精神障碍和共病物质使用障碍。参与者被分配到一个为期15节的实验组干预或为期2节的对照组干预,并观察18个月。试验前有性行为的59名参与者是干预的主要目标。性风险行为是主要结局。
在5且有性行为的男性中,初始6个月随访时获得了59名(100%)的随访数据,18个月随访剩余时间获得了56名(95%)的随访数据。在初始6个月随访期间,实验组性风险指数的平均得分比对照组低3倍(1.0对3.1;P=0.01),在18个月随访剩余时间低2倍。结论:这种干预成功降低了患有精神疾病的无家可归男性的性风险行为。效果在18个月内有所减弱但并未消失。类似方法可能对其他弱势群体高危人群有效。
