Introduction:
The 20-item Obsessive-Compulsive Trait Core Dimensions Questionnaire (OCTCDQ) assesses two motivational dimensions of OCD, harm avoidance and incompleteness.
Method:
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.
Results:
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.
Conclusion:
The OCTCDQ-R is a reliable and valid measure to assess the individual significance of incompleteness and harm avoidance in OCD patients.
