Epistemic trust (ET) refers to the predisposition to trust information as authentic, trustworthy and relevant to the self. Epistemic distrust – resulting from early adversity – may interfere with openness to social learning within the therapeutic encounter, reducing the ability to benefit from treatment. The self-report Questionnaire Epistemic Trust (QET) is a newly developed instrument that aims to assess ET. This study presents the first results on the psychometric properties of the QET in both a community and a clinical sample. Our findings indicate that the QET is composed of four meaningful subscales with good to excellent internal consistency. The QET shows relevant associations with related constructs like personality functioning, symptom distress and quality of life. QET scores clearly distinguish between a clinical and community sample and are associated with the quality of the therapeutic alliance. The QET provides a promising, brief and user-friendly instrument that could be used for a range of clinical and research purposes. Future studies with larger samples are needed to strengthen construct validity and to investigate the value of the QET to predict differential treatment responses or to study mechanisms of change.

认知信任问卷（QET）的开发和心理测量评估：认知信任的自我报告评估

认知信任（ET）是指相信信息是真实的、值得信赖的并且与自我相关的倾向。早期逆境造成的认知不信任可能会干扰治疗过程中社会学习的开放性，从而降低从治疗中受益的能力。自我报告认知信任问卷（QET）是一种新开发的工具，旨在评估 ET。这项研究展示了社区和临床样本中 QET 心理测量特性的第一个结果。我们的研究结果表明，QET 由四个有意义的子量表组成，具有良好到极好的内部一致性。QET 显示了与人格功能、症状困扰和生活质量等相关结构的相关关联。QET 评分清楚地区分临床样本和社区样本，并且与治疗联盟的质量相关。QET 提供了一种有前途、简洁且用户友好的仪器，可用于一系列临床和研究目的。未来需要进行更大样本的研究，以加强结构有效性并研究 QET 的价值，以预测不同的治疗反应或研究变化机制。
