Gay and bisexual men (GBM) report higher rates of methamphetamine use compared to heterosexual men, and thus have a heightened risk of developing problems from their use. We examined treatment outcomes among GBM clients receiving outpatient counseling at a lesbian, gay, bisexual, transgender and intersex (LGBTI)-specific, harm reduction treatment service in Sydney, Australia. GBM receiving treatment for methamphetamine use from ACON's Substance Support Service between 2012-15 (n = 101) were interviewed at treatment commencement, and after 4 sessions (n = 60; follow-up 1) and 8 sessions (n = 32; follow-up 2). At each interview, clients completed measures of methamphetamine use and dependence, other substance use, injecting risk practices, psychological distress and quality of life. The median age of participants was 41 years and 56.4% identified as HIV-positive. Participants attended a median of 5 sessions and attended treatment for a median of 112 days. There was a significant reduction in the median days of methamphetamine use in the previous 4 weeks between baseline (4 days), follow-up 1 (2 days) and follow-up 2 (2 days; p = .001). There was a significant reduction in the proportion of participants reporting methamphetamine dependence between baseline (92.1%), follow-up 1 (78.3%) and follow-up 2 (71.9%, p < .001). There were also significant reductions in psychological distress (p < .001), and significant improvements in quality of life (p < .001). Clients showed reductions in methamphetamine use and improved psychosocial functioning over time, demonstrating the potential effectiveness of a LGBTI-specific treatment service.
与异性恋男性相比，男同性恋者和双性恋男性（GBM）报告的甲基苯丙胺使用率更高，因此使用该药物产生问题的风险也更高。我们在澳大利亚悉尼一家专门针对女同性恋、男同性恋、双性恋、跨性别者和双性人（LGBTI）的减少伤害治疗服务机构，对接受门诊咨询的GBM客户的治疗结果进行了研究。对2012年至2015年间在ACON物质支持服务中心接受甲基苯丙胺使用治疗的GBM（n = 101）在治疗开始时、4次治疗后（n = 60；随访1）和8次治疗后（n = 32；随访2）进行了访谈。在每次访谈中，客户完成了甲基苯丙胺使用和依赖、其他物质使用、注射风险行为、心理困扰和生活质量的测量。参与者的中位年龄为41岁，56.4%的人被确定为艾滋病毒阳性。参与者平均参加了5次治疗，治疗时间中位数为112天。在基线时（4天）、随访1（2天）和随访2（2天；p = .001），前4周甲基苯丙胺使用的中位数天数有显著减少。报告甲基苯丙胺依赖的参与者比例在基线时（92.1%）、随访1（78.3%）和随访2（71.9%，p < .001）有显著下降。心理困扰也有显著减少（p < .001），生活质量有显著改善（p < .001）。随着时间的推移，客户的甲基苯丙胺使用减少，心理社会功能得到改善，证明了专门针对LGBTI的治疗服务的潜在有效性。
