Memory and attention performance in psychiatric patients: lack of correspondence between clinician-rated and patient-rated functioning with neuropsychological test results.
In the present study, the correspondence between clinician-assessed and self-reported neurocognitive performance was contrasted with scores obtained from psychometric neuropsychological tests in 148 psychiatric in-patients. Results revealed that self-reported cognitive functioning was strongly associated with depressive symptomatology but was only poorly related to psychometric neurocognitive performance, particularly in schizophrenia. After illness denial was controlled for, the overall association between subjective and objective test performance was slightly increased but still failed to reach significance in six out of eight analyses. In approximately 20% to 40% of all cases, clinicians judged memory performance to be normal despite substantial impairment revealed by neuropsychological test results (attention parameters: 7-51%). Since (ecological) validity and reliability have been demonstrated for many neurocognitive paradigms, the present results question the validity of non-psychometric neurocognitive assessment and call for a complementation of clinical judgment with neurocognitive assessment. Reasons for decreased sensitivity of self-reported and clinician-assessed neurocognitive functioning are discussed.
