A substantial number of sexual assault victims report experiencing some form of peritraumatic tonic immobility (TI). A self-report questionnaire that is widely used to assess TI retrospectively is the Tonic Immobility Scale (TIS). This study explored the factor structure of the TIS in a clinical sample of adolescent and young adults.
The sample comprised 131 female rape victims, aged 13-25, who were referred for specialized trauma-focused treatment. An exploratory factor analysis (EFA) was performed.
The EFA showed support for a three-factor model, with factors TI, Fear, and Detachment. Item correlations ranged from .32 to .57 for TI, from .14 to .35 for Fear, and .29 for the two Detachment items.
We found support for a three-factor solution distinguishing TI, fear, and detachment, suggesting the need to further develop the TIS with different subscales in varying age groups and clinical samples. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
大量性侵犯受害者报告经历某种形式的创伤性强直不动（TI）。一种广泛用于回顾性评估 TI 的自我报告问卷是强直不动量表（TIS）。本研究探讨了 TIS 在青少年和年轻成年人临床样本中的因子结构。
该样本包括 131 名年龄在 13-25 岁之间的女性强奸受害者，他们因专门的创伤聚焦治疗而被转介。进行了探索性因素分析（EFA）。
EFA 支持三因素模型，包括 TI、恐惧和分离三个因素。TI 的项目相关性范围为.32 至.57，恐惧为.14 至.35，两个分离项目为.29。
我们发现支持区分 TI、恐惧和分离的三因素解决方案，这表明需要进一步开发 TIS，为不同年龄段和临床样本开发不同的子量表。（PsycInfo 数据库记录（c）2022 APA，保留所有权利）。
