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 (n = 300 unselected, n = 349 nonclinical, and n = 197 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 with nonclinical sample. Results suggest the RSI is a valid and reliable measure that may be useful in clinical and research settings.

松弛敏感性指数的开发和初步验证


放松敏感性反映了对放松相关事件的恐惧。本研究的目的是开发放松敏感性自我报告测量方法，即松弛敏感性指数 (RSI)，并对其进行初步验证。三个独立的本科生样本（n = 300 名未选择的学生，n = 349 名非临床学生，n = 197 名焦虑/抑郁症状加重的学生）完成了自我报告措施，以检查 RSI 的因素结构、可靠性和有效性。探索性和验证性因素分析的结果支持三因素结构（相关的身体、认知和社会问题）。 RSI 表现出良好的内部一致性和结构有效性，与焦虑和抑郁症状测量的预期相关性证明了这一点。 RSI 在对放松的恐惧反应历史方面显示出良好的预测有效性。与非临床样本相比，有症状样本的 RSI 评分显着更高。结果表明 RSI 是一种有效且可靠的测量方法，可能在临床和研究环境中有用。
