Tonic immobility (TI) is an involuntary component of the fear response that is characterized by freezing or immobility in situations involving extreme fear coupled with physical restraint. The present investigation evaluated the factor structure of the Tonic Immobility Scale (TIS; Forsyth, J. P., Marx, B., Fusé, T. M. K., Heidt, J., & Gallup, G. G., Jr. (2000). The Tonic Immobility Scale. Albany, NY: Authors)--a newly developed measure to assess components of TI in female sexual assault survivors. Study 1 (N=88) consisted of an Exploratory Factor Analysis of sexual assault survivors' responses on the TIS, whereas Study 2 (N=191) involved a Confirmatory Factor Analysis (CFA) with a second independent sample of female sexual assault survivors. Findings from both studies suggest that the TIS is comprised of two independent factors: physical immobility and fear. Findings are discussed in terms of the theoretical and practical implications of the factor solution obtained, particularly with regard to evaluating TI in adult survivors of sexual assault.
紧张性不动（TI）是恐惧反应的一个非自愿组成部分，其特征是在涉及极端恐惧并伴有身体限制的情况下出现僵住或不动。本研究评估了紧张性不动量表（TIS；福赛思，J.P.，马克思，B.，富泽，T.M.K.，海德特，J.，& 小盖洛普，G.G.（2000年）。紧张性不动量表。纽约州奥尔巴尼：作者）——一种新开发的用于评估女性性侵犯幸存者TI组成部分的测量工具。研究1（N = 88）包括对性侵犯幸存者在TIS上的反应进行探索性因素分析，而研究2（N = 191）涉及对另一组独立的女性性侵犯幸存者样本进行验证性因素分析（CFA）。两项研究的结果表明，TIS由两个独立因素组成：身体不动和恐惧。根据所获得的因素解决方案的理论和实际意义对研究结果进行了讨论，特别是在评估成年性侵犯幸存者的TI方面。
