目的。这项研究使用潜在转变分析(LTA)的纵向动态方法，在一年的时间里确定了女性如何自然地通过避孕套使用的跨理论模型阶段。作为女性人类免疫缺陷病毒风险更大研究的一部分，参与者接受了两次避孕套使用阶段的评估，时间间隔为1年。共有491名完成了两项研究评估的女性被包括在这项分析中。避孕套的使用阶段通过两个问题进行评估，这两个问题将女性置于避孕套使用的五个改变阶段之一(α=.90)。潜伏性转换分析确定了自然主义阶段进展的最佳模型，该模型包括向前和向后移动。预想和维持阶段被发现是最稳定的阶段(超过50%的参与者在一年后保持在该阶段)，而行动阶段最不稳定(15%保持在该阶段)。所有阶段的转移概率在样本中显示出较高的复发率。如果不采取任何干预措施，很高比例的妇女将在一年内仍处于使用避孕套的阶段。旨在增加妇女使用避孕套的干预措施需要包括预防复发。此外，各阶段的过渡概率将有助于为干预计划建立合理的变化率。
Purpose. This study identifies how women naturally progress through the Transtheoretical Model stages of condom use over a 1 year period using the longitudinal dynamic methodology of latent transition analysis (LTA).Design. As part of a larger study of human immunodeficiency virus risk in women, participants were assessed for their stage of condom use two times, 1 year apart.Subjects. A total of 491 women who completed both assessments of the study were included in this analysis.Measures. Stage of condom use was assessed using two questions, which placed women into one of five stages of change for condom use (alpha = .90).Results. Latent transition analysis identified the best-fitting model of naturalistic stage progression, which included both forward and backward movement. Precontemplation and maintenance were found to be the most stable stages (more than 50 % of the participants remaining in that stage 1 year later), and the action stage was the least stable (15 % remaining in this stage). Transition probabilities for all stages showed a high rate of relapse in the sample.Conclusions. A high proportion of women will remain within their stage of condom use over a 1-year period if no intervention is introduced. Interventions that are aimed at in creasing condom use in women need to incorporate relapse prevention. In addition, the transition probabilities for the stages will help establish reasonable rates of change for intervention programs.
