Relaxation sensitivity indexes the fear of relaxation-related events. The purpose of this study was to develop and provide initial validation of a self-report measure of relaxation sensitivity, the Relaxation Sensitivity Index (RSI). Three independent samples of undergraduate students (=300 unselected, =349 non-clinical, and =197 clinical analogs with elevated anxiety/depression symptoms) completed self-report measures to examine the factor structure, reliability, and validity of the RSI. Results of exploratory and confirmatory factor analyses supported a three-factor structure (correlated Physical, Cognitive, and Social Concerns). The RSI demonstrated good internal consistency and construct validity as evidenced by expected correlations with measures of anxiety and depression symptoms. The RSI showed good predictive validity in terms of a history of fearful responding to relaxation. RSI scores were significantly higher in the symptomatic compared to non-clinical sample. Results suggest the RSI is a valid and reliable measure that may be useful in clinical and research settings.
放松敏感性指对与放松相关事件的恐惧。本研究的目的是开发一种自我报告的放松敏感性测量工具——放松敏感性指数（RSI），并进行初步验证。三个独立的本科生样本（未筛选的300名、非临床的349名以及有焦虑/抑郁症状升高的197名临床模拟者）完成了自我报告测量，以检验RSI的因子结构、信度和效度。探索性和验证性因子分析结果支持三因子结构（相关的身体、认知和社会担忧）。RSI表现出良好的内部一致性和结构效度，这从与焦虑和抑郁症状测量的预期相关性中得到证明。就对放松产生恐惧反应的历史而言，RSI显示出良好的预测效度。与非临床样本相比，有症状样本的RSI得分显著更高。结果表明，RSI是一种有效且可靠的测量工具，可能在临床和研究环境中有用。
