The 20-item Obsessive-Compulsive Trait Core Dimensions Questionnaire (OCTCDQ) assesses two motivational dimensions of OCD, harm avoidance and incompleteness.
Psychometric properties and construct validity of a German version were examined in 202 patients with OCD. A shortened and statistically optimized version was developed on the basis of a structural equation modelling approach.
As a confirmatory factor analysis showed a poor model fit for the German translation, the model was revised. The resulting 10-item version (OCTCDQ-R) showed a good fit. Internal consistency is excellent for incompleteness and satisfactory for harm avoidance. Relationships with OCD symptom severity, anxiety, worry and obsessive-compulsive personality traits support the construct validity.
The OCTCDQ-R is a reliable and valid measure to assess the individual significance of incompleteness and harm avoidance in OCD patients.
20项强迫特质核心维度问卷（OCTCDQ）评估强迫症的两个动机维度，即伤害回避和不完整感。
对202名强迫症患者的德文版进行心理测量特性和结构效度检验。基于结构方程建模方法开发了一个缩短且经统计优化的版本。
由于验证性因素分析显示德文翻译版模型拟合不佳，因此对模型进行了修订。最终得到的10项版本（OCTCDQ-R）显示出良好的拟合度。不完整感维度的内部一致性极佳，伤害回避维度的内部一致性令人满意。与强迫症症状严重程度、焦虑、担忧及强迫型人格特质的关系支持了结构效度。
OCTCDQ-R是评估强迫症患者中不完整感和伤害回避的个体重要性的可靠且有效的测量工具。
