Ability to counselors to detect cognitive impairment among substance-abusing patients: an examination of diagnostic efficiency.
Counselors (N = 12) in 1 of 2 substance abuse treatment facilities were asked to identify which of their patients (N = 97) had general neurocognitive impairment. Counselors were required to base their judgements on information collected from patients during psychosocial history gathering, clinical interviews, physical examinations, brief cognitive screening tests, and substance abuse severity evaluations, but not on neuropsychological test results. All patients were subsequently administered a neuropsychological test battery. Diagnostic agreement between counselors' impressions of patients' cognitive status and patients' actual neuropsychological test performance was poor. Subsequent analyses revealed counselors' impressions about patients' neuropsychological functioning were based on information that did not reliably discriminate between cognitively impaired and intact patients (e.g., years of education and self-reported symptoms of cognitive dysfunction).
