A longitudinal study of patterns of sexual behavior among asymptomatic, homosexual males in New York City was conducted. Participants were interviewed at two time points, 6 months apart. Based on their reports of sexual behavior during a recent 'typical' month, respondents were classified at each time point as engaging in safer (or low-risk) sexual practices versus high-risk sexual behaviors. Discriminant analysis was employed to distinguish the 53 males classified as risky at both time 1 and time 2 from the 47 males classified as safer in both periods. Statistically significant discrimination was achieved with 10 psychosocial predictor variables, four of which were significant while controlling for all other variables in the model. Of these predictors, drug use within sexual contexts was particularly noteworthy, since it provided the greatest relative contribution to the discriminant function and appears to be an important candidate for educational intervention. Other significant variables included perceived adequacy of emotional support, number of years engaged in regular sexual intercourse with other males, and perceived difficulty in modifying sexual behavior. Self-esteem and alcohol consumption approached significance.
对纽约市无症状同性恋男性的性行为模式进行了一项纵向研究。参与者在相隔6个月的两个时间点接受了访谈。根据他们在最近一个“典型”月的性行为报告,受访者在每个时间点被分类为进行更安全(或低风险)的性行为与高风险性行为。采用判别分析来区分在时间1和时间2都被分类为有风险的53名男性与在两个时期都被分类为更安全的47名男性。使用10个心理社会预测变量实现了具有统计学意义的判别,其中4个变量在控制模型中的所有其他变量时具有显著性。在这些预测变量中,性情境中的药物使用尤其值得注意,因为它对判别函数的相对贡献最大,并且似乎是教育干预的一个重要候选因素。其他显著变量包括感知到的情感支持充足程度、与其他男性进行定期性交的年数以及感知到的改变性行为的难度。自尊和饮酒接近显著性。
