Abstract

Introduction

: Tonic immobility (TI) in humans is characterized by muscle inhibition, hypertonia and analgesia that may occur during a traumatic event. TI is associated with an increased risk of severe and treatment-resistant post-traumatic stress disorder (PTSD). To date, there is no French validated scale for TI.

Methods

: We studied the face validity (qualitative study) and psychometric properties concerning a French version of the 10-item Tonic Immobility Scale (FR-TIS) in adult with PTSD.

Results

: Concerning face validity, six participants confirmed that the FR-TIS was simple, clear, and comprehensible, but has some limitations concerning the recall according to age of trauma, peritraumatic dissociation intensity, avoidance behaviors, the type and the context of the trauma. For psychometric properties, 120 patients completed a computerized version of the FR-TIS. FR-TIS showed good psychometric properties in a three-dimensional form with 8 items (Root Mean Square Error of Approximation (RMSEA) = 0.056) including 4 items for TI (Cronbach's α = 0.76), 2 items for fear (Cronbach's α = 0.63), 2 items for dissociation (Cronbach's α = 0.68).

Conclusion

: The FR-TIS is a potentially useful and easy-to-use tool in clinical practice, to help improving screening and assessment of TI

法国对创伤后应激障碍患者强直性不运动量表的验证

简介人类强直性静止（TI）的特点是在创伤事件中可能出现肌肉抑制、肌张力亢进和镇痛。强直性静止与严重的创伤后应激障碍（PTSD）风险增加和治疗耐受性增加有关。迄今为止，法国还没有针对创伤后应激障碍的有效量表：我们研究了法文版 10 项强直性静止量表（FR-TIS）在成人创伤后应激障碍患者中的面效度（定性研究）和心理测量特性：关于面效性，6 名参与者证实 FR-TIS 简单、清晰、易懂，但在根据创伤年龄、创伤周围解离强度、回避行为、创伤类型和背景进行回忆方面存在一些局限性。在心理测量特性方面，120 名患者完成了 FR-TIS 的计算机化版本。FR-TIS以三维形式显示出良好的心理测量特性，共有8个项目（近似均方根误差（RMSEA）= 0.056），其中包括4个TI项目（Cronbach's α = 0.76）、2个恐惧项目（Cronbach's α = 0.63）和2个解离项目（Cronbach's α = 0.68）：结论：FR-TIS 是临床实践中一种潜在有用且易于使用的工具，有助于改善 TI 的筛查和评估。
