ABSTRACT
OBJECTIVE: Prior work suggests executive dysfunction (ED) on the Stroop Color and Word Test (SCWT) and the Mattis Dementia Rating Scale-2 Initiation/Perseveration subscale (DRS IP) predicts poor antidepressant response in late-life depression. This study examined if either patient perception of ED or the Trail Making Test Part B (TMT-B) could identify patients with impairment on the SCWT or DRS IP. METHODS: Patients were 65 or older and had a diagnosis of major depression without dementia. Cognition was assessed with the TMT-B, the SCWT, and the DRS IP. A self-reported Perceived Deficits Questionnaire (PDQ) subscale assessed patients' perceptions of ED. RESULTS: In 247 participants (mean age 71.3 years), the PDQ subscale was not associated with test performance. The sensitivity of the TMT-B in identifying impairment on the SCWT or DRS IP was low (35% and 23%, respectively). CONCLUSION: Neither the TMT-B nor self-reports are useful screening tools for ED on the SCWT or DRS IP.
