Background: In an aging society, neuropsychological testing using video teleconferencing (VTC) is increasingly important. Despite the potential benefit of a VTC-administered Montreal Cognitive Assessment Tool (MoCA) to detect cognitive decline, only a limited number of studies have investigated this tool's reliability. Therefore, we aimed to evaluate the reliability of VTC-administered MoCA compared with face-to-face (FTF)-administered MoCA among elderly Japanese participants. Moreover, we examined participants' satisfaction with VTC-administered MoCA. Methods: Participants ‡60 years of age with and without cognitive impairment (i.e., those with mild cognitive impairment [MCI], those with dementia, and healthy controls [HC]) were assessed with VTC- and FTF-administered MoCA at an interval of >2 weeks and <3 months. The order effect (VTC first vs. FTF first) and time effect (first vs. second testing session), as well as several covariates such as age and years of education were controlled. Intraclass correlation coefficients (ICCs) were calculated using a mixed-effects model to assess the agreement between the two (VTC- vs. FTF-administered) groups. Participants' satisfaction with VTC-administered MoCA was examined using a Likert scale asking seven questions. Results: We included 73 participants in the study (36 men; age, 76.3 - 7.5 years). The ICC for the MoCA total score was high in the entire sample (0.85), whereas ICCs were moderate to high for the subgroups (MCI: 0.82, dementia: 0.82, and HC: 0.53). Furthermore, we found good overall participant satisfaction with VTC-administered MoCA. Discussion: VTC-administered MoCA appears viable as an alternative to FTF-administered MoCA, although further replication studies with larger sample sizes are needed.
