Klinisk utprøving av WISC-V

Two-hundred and thirty-six WISC-V protocols from children assessed in the Child Psychiatric Clinic of Vestfold Hospital Trust took part in the study. We analyzed four issues known either to be specifically important or to be problematic in previous Wechsler adaptions. The first issue relates to whether the items on the translated verbal tests show the expected decreasing frequency of correct answers. Second, we check for invariance of the five-factor structure across age and gender groups. Third, we assess whether the new visual span test varies sufficiently from digit span to defend having two span tests. Fourth, we report the Cronbach’s alpha levels in the clinical sample and check for possible verbal items decreasing reliability. The analyses showed small insufficiencies, and thus we conclude that the test also maintains the necessary psychometric capacity in a clinical sample.
