Background: Learning potential, a dynamic multi-administration approach to assessment, is claimed to predict functional outcome in schizophrenia better than traditional single-administration neuropsychological tests. Aims: This study investigates the relation between learning potential and clinical and demographic variables, social functioning and neuropsychological abilities in a sample of 30 participants with schizophrenia with a mean IQ score within the normal range (mean Wechsler Abbreviated Scale of Intelligence (WASI) IQ=106). Methods: Two Wisconsin Card Sorting Test (WCST) based methods for assessing learning potential are compared. Results: The dimensional approach (calculation of gain scores following training) identified one aspect of executive functioning (set shifting) to be related to learning potential. Associations with other neuropsychological tests and social functioning were however limited. The categorical approach (separating high-achievers from learners and non-learners) was not sensitive within this normal IQ sample. Conclusions: Although there seems to be a relation between learning potential and some aspects of executive functioning, the two existing WCST methods should be used with caution when assessing learning potential in individuals with schizophrenia who have IQ scores within the normal range.
