Abstract

This paper examines the utility of the Trauma Symptom Inventory-2 (TSI-2) and its predecessor, the Trauma Symptom Inventory (TSI) in forensic psychology practice. The instrument’s psychometric properties, use with special populations, legal case review and admissibility considerations are discussed. Recommendations regarding the strengths and limitations of the TSI/TSI-2 are suggested for forensic practitioners and lawyers. Considerations related to potential expert witness cross-examination are also presented. Psychological research and legal review suggest that the TSI/TSI-2 is admissible as an instrument under the Daubert Standard, especially as related to civil court disability claims. Still, lingering issues with the ATR validity scale remain and there is limited independent research establishing the predictive and discriminant validity of the TSI-2 across diverse forensic samples. In summary, this suggests the instrument is most effective as part of a comprehensive assessment battery for identifying PTSD symptomology within legal proceedings where a trauma diagnosis is relevant.

摘要

本文研究了创伤症状清单 2 (TSI-2) 及其前身创伤症状清单 (TSI) 在法医心理学实践中的效用。讨论了该仪器的心理测量特性、特殊人群的使用、法律案件审查和可受理性考虑。建议法医从业者和律师就 TSI/TSI-2 的优势和局限性提出建议。还介绍了与潜在的专家证人交叉询问有关的考虑。心理学研究和法律审查表明，TSI/TSI-2 可作为Daubert下的工具标准，特别是与民事法庭残疾索赔有关的。尽管如此，ATR 有效性量表仍然存在挥之不去的问题，并且在不同的法医样本中建立 TSI-2 的预测和区分有效性的独立研究有限。总之，这表明该工具作为综合评估组合的一部分是最有效的，用于在与创伤诊断相关的法律诉讼中识别 PTSD 症状。
