使用感知压力量表(PSS)，对111名乳腺癌手术后的女性进行了总体压力感知评估，在12个月和24个月后，这是第一个对PSS进行因素分析的研究。每一次的PSS数据均采用探索性因素分析，采用斜交直接四分旋转法。拟合优度指数(近似均方根误差[RMSEA])、因素载荷的大小和模式以及可信区间数据揭示了正负应力项目的双因素解。随着时间的推移，这些发现也表明了因素的稳定性。等级因素分析支持二阶因素“感受到的压力”。PSS的这一替代因子模型与关于该测量在癌症研究中的使用的观察一起提出。
Using the Perceived Stress Scale (PSS), perceptions of global stress were assessed in 111 women following breast cancer surgery and at 12 and 24 months later This is the first study to factor analyze the PSS. The PSS data were factor analyzed each time using exploratory factor analysis with oblique direct quartimin rotation. Goodness-of-fit indices (root mean square error of approximation [RMSEA]), magnitude and pattern of factor loadings, and confidence interval data revealed a two-factor solution of positive versus negative stress items. The findings, replicated across time, also indicate factor stability. Hierarchical factor analyses supported a second-order factor of "perceived stress." This alternative factor model of the PSS is presented along with observations regarding the measure's use in cancer research.
