评估新建立的性关系中性交次数对避孕套使用情况的影响。在12周的研究间隔期间报告至少有一个新伴侣的参与者（N=115；年龄18-29岁；48%的女性；90%的非洲裔美国人）完成了每周性传播感染检测和每日三次电子日记收集，评估个人和伴侣特定的影响、日常活动、性行为和避孕套的使用。我们分析了事件级避孕套使用百分比和被试级行为反应效应。使用广义加性混合模型（GAMMs）通过随机效应估计伴侣内和受试者内相关性的安全套使用概率。在新关系中，男性在第一次性行为中使用避孕套的平均概率为55%，女性为36%。分析表明，估计避孕套使用概率的平滑形状在两性中是相似的，并使用GAMMs进行拟合。相对较高的避孕套使用率之后，在前9次性行为中急剧下降，男性下降到16%，女性下降到8%。女性避孕套使用率的快速下降与更高的关系水平和性满意度高度相关。无论男性还是女性，在早期的性行为积累之后，使用避孕套的可能性都会急剧下降。关系和性满意度也影响避孕套使用率的下降，尤其是在女性中。
Assess condom use as a function of number of coital events in newly formed sexual relationships. Participants who reported at least one new partner during the 12-week study interval (N=115; ages 18–29 years; 48% women; 90% African American) completed weekly sexually transmitted infections testing and three-times daily electronic diary collection assessing individual and partner-specific affect, daily activities, sexual behavior and condom use. We analyzed event-level condom use percentage and subject-level behavior response effects. Generalized Additive Mixed Models (GAMMs) were used to estimate condom use probability accounting for within-partner and within-subject correlations via random effects. The average condom use probability at the first coital event in new relationships was 55% for men and 36% for women. Analyses showed that smooth shapes of estimated condom use probabilities were similar for both sexes and were fitted using GAMMs. Relatively higher condom use percentage was followed by a sharp decline during the first 9 coital events decreasing to 16% for men and 8% for women. More rapid decline in condom use among women was highly associated with higher levels of relationship and sexual satisfaction. The likelihood of condom use declines sharply for both men and women after the early accrual experience with a partner. Relationship and sexual satisfaction also influence declines in condom use, especially among women.
