ABSTRACT: The Learning Disability Screening Questionnaire (LDSQ) was developed primarily to provide a short and effective screening instrument to indicate possible intellectual disability amongst per-sons who come in contact with the service system. This study examined the validity of the Norwegian version of LDSQ in a sample of 35 subjects. All participants were outpatients referred for neuropsychological examinations. WAIS-III full-scale score was used for criterion validity. At a stated cut-off score of 46.6%, LDSQ showed several false negatives and false positives but no true positives. This raises the question of whether this test represents a valid screening instrument for learning disabilities in a clinical sample.
