Summary
The Dutch translation of the Dimensional Assessment of Personality Pathology-Basic Questionnaire (DAPP-BQ) demonstrates satisfactory reliability and validity. Its factor structure largely aligns with the original, supporting a dimensional model of personality pathology.
Area of Science:
- Psychology
- Psychometrics
- Personality Disorders
Background:
- The Dimensional Assessment of Personality Pathology-Basic Questionnaire (DAPP-BQ) is a key instrument for assessing personality pathology.
- Validation of translated instruments is crucial for cross-cultural research and clinical application.
Purpose of the Study:
- To evaluate the psychometric properties of the Dutch translation of the DAPP-BQ.
- To examine the factor structure and convergent validity of the Dutch DAPP-BQ.
Main Methods:
- Item-total correlations were used to select valid items.
- Cronbach's alpha coefficients assessed internal consistency.
- Factor analysis and correlation analyses were employed to examine structure and validity.
Main Results:
- The Dutch DAPP-BQ showed satisfactory reliability.
- Factor analysis revealed a four-factor structure, largely consistent with the original Canadian version.
- Correlations with the Four-Dimensional Personality Test supported the convergent validity of the Dutch DAPP-BQ factors.
Conclusions:
- The Dutch DAPP-BQ is a reliable and valid measure for assessing personality pathology.
- Findings support the dimensional model of personality disorder and the utility of the DAPP-BQ in Dutch-speaking populations.
