The Cognitive Distortions Questionnaire (CD-Quest) is an instrument that identifies logical errors or cognitive distortions and is used in trial-based cognitive therapy (TBCT). However, it had previously only been available for adults.
To develop and validate a version of the CD-Quest for teens (CD-Quest-T) aged 11 to 17 years and test its psychometric properties.
A total of 299 schoolchildren participated in the investigation. After content validity was assessed, the language was adapted for the target age group, and the length of the instrument was reduced to eight items (from the initial 15). Five cognitive therapists analyzed the content and structure of the items. Finally, to investigate the construct validity of the CD-Quest-T, the instrument was divided into a full scale and two subscales, which measure the frequency of the distortions and the intensity attributed to them, respectively.
The overall internal consistency of the scale was α = 0.77, whereas subscale indices were α = 0.75 for the frequency scale and α = 0.73 for the intensity scale. Results from exploratory factor analysis and concurrent validity analysis indicated that the CD-Quest-T items have good psychometric properties and generate scores reliably.
The psychometric properties of the CD-Quest-T demonstrate its adequacy for measurement of cognitive distortions in adolescents.
认知扭曲问卷（CD-Quest）是一种识别逻辑错误或认知扭曲的工具，用于基于试验的认知疗法（TBCT）。然而，它之前仅适用于成年人。
开发和验证适用于 11 至 17 岁青少年的认知扭曲问卷版本（CD-Quest-T），并测试其心理测量特性。
共有 299 名学童参与了调查。在评估内容有效性后，对语言进行了调整以适应目标年龄组，并将仪器的长度缩短至 8 个项目（从最初的 15 个）。五位认知治疗师分析了项目的内容和结构。最后，为了研究 CD-Quest-T 的构念效度，将该工具分为完整量表和两个分量表，分别衡量扭曲的频率和归因于它们的强度。
该量表的整体内部一致性为α=0.77，而频率量表的子量表指标为α=0.75，强度量表的子量表指标为α=0.73。探索性因素分析和同时有效性分析的结果表明，CD-Quest-T 的项目具有良好的心理测量特性，能够可靠地生成分数。
CD-Quest-T 的心理测量特性表明其适用于测量青少年的认知扭曲。
