We investigated the validity, reliability, and feasibility of the Montreal Cognitive Assessment 5-minute protocol (MoCA 5-minute protocol) administered over the telephone. Four items examining attention, verbal learning and memory, executive functions/language, and orientation were extracted from the MoCA to form the MoCA 5-minute protocol. One hundred four patients with stroke or transient ischemic attack, including 53 with normal cognition (Clinical Dementia Rating, 0) and 51 with cognitive impairment (Clinical Dementia Rating, 0.5 or 1), were administered the MoCA in clinic and a month later, the MoCA 5-minute protocol over the telephone. Administration of the MoCA 5-minute protocol took 5 minutes over the telephone. Total score of the MoCA 5-minute protocol...

This study examined the validity and reliability of the Neuropsychiatric Inventory Questionnaire ... more This study examined the validity and reliability of the Neuropsychiatric Inventory Questionnaire version (NPI-Q), a proxy-reported format of the interview-based NPI, in assessing neuropsychiatric symptoms in 173 patients with stroke or transient ischemic attack (TIA) having cognitive impairment. The NPI-Q was validated against the NPI as a gold standard. Informants took approximately 7 minutes to complete the NPI-Q. Bland-Altman analysis revealed a bias of 0.7 points, with 95% limits of agreement between -8.6 and 10.0 between the total symptom scores of the NPI and NPI-Q. The NPI-Q correlated significantly with the NPI in individual and total symptom scores and caregiver distress scores. In predicting presence of symptoms on the NPI, the NPI-Q yielded, on average, sensitivity of 74.1% and specificity of 79.5%. On the NPI-Q, informants tended to overreport symptoms in patients with less severe symptoms but underreport with increasing symptom severity. Internal consistency of the NPI-Q was acceptable (Cronbach's α = 0.756). One-week test-retest reliability of the NPI-Q was excellent (intraclass correlation coefficient = .990). The NPI-Q is a valid and reliable instrument for screening neuropsychiatric symptoms in patients with stroke and TIA.
