In two studies the psychometric qualities of the short Dutch Schema Questionnaire (SV-vv) were investigated. In a first study the internal consistency and the test-retest reliability of the SV-vv were examined in a student sample (N=330). The results indicated that for each scale of the SV-vv, adequate to high values on both reliability coefficients were reached. In a second study the internal consistency, the concurrent validity, and the discriminative validity of the SV-vv were estimated in a mixed clinical and non-clinical sample (N=300). Again high internal consistency for each scale of the SV-vv was yielded. Moreover, a high level of concurrent and discriminative validity was found for the schema scales. So, good to excellent psychometric properties were found for the SV-vv, making the instrument readily suitable for clinical practice.
