Abstract

The Learning Disability Screening Questionnaire (LDSQ), a brief screening tool for intellectual disability, was originally validated against the Weschler Adult Intelligence Scale, Third Edition (WAIS-III), which was superseded by the Weschler Adult Intelligence Scale, Fourth Edition (WAIS-IV) in the United Kingdom in 2010. This study examines the performance of the LDSQ using the WAIS-IV as the diagnostic intellectual assessment. Based on the original optimal cut-off score, the LDSQ sensitivity value was equivalent (91%) to that obtained in the original validation study, and the specificity value was higher at 92%. This suggests that the LDSQ remains valid when using the WAIS-IV as the comparative intellectual assessment.
