Based on typical everyday trust situations, a short and ecologically valid self-report instrument for the assessment of interpersonal trust was developed (Interpersonal Trust Scenario Questionnaire [ITSQ]). Data from 1,359 clinical and nonclinical participants were analyzed to examine psychometric properties and group differences. The authors assessed interpersonal trust in patients with borderline personality disorder (BPD), patients with major depressive disorder, and patients with social anxiety disorder. Lastly, the relationship between interpersonal trust and the perceived quality of the therapeutic alliance was examined. The ITSQ showed satisfactory reliability (Cronbach's α = 0.72). Convergent validity and discriminant validity were obtained for correlations with a hypothetical trust game, another interpersonal trust scale (KUSIV-3), risk propensity, optimism and pessimism, and the HEXACO-60. Patients with BPD showed the lowest interpersonal trust scores of all groups. Interpersonal trust and the perceived quality of the therapeutic alliance were significantly associated only in the group of patients with BPD.

人际信任：边缘型人格障碍患者自我报告量表的开发和验证及其临床应用

基于典型的日常信任情况，开发了一种用于评估人际信任的简短且生态有效的自我报告工具（人际信任情景问卷 [ITSQ]）。分析了来自 1,359 名临床和非临床参与者的数据，以检查心理测量特性和群体差异。作者评估了边缘型人格障碍 (BPD) 患者、重度抑郁症患者和社交焦虑症患者的人际信任。最后，检验了人际信任与治疗联盟感知质量之间的关系。ITSQ 显示出令人满意的可靠性（Cronbach's α = 0.72）。对于与假设信任博弈、另一个人际信任量表 (KUSIV-3) 的相关性，获得了收敛效度和判别效度，风险倾向、乐观和悲观以及 HEXACO-60。BPD 患者在所有组中表现出最低的人际信任评分。人际信任和治疗联盟的感知质量仅在 BPD 患者组中显着相关。
