Objective:
Neuropsychological assessment through VideoTeleConferencing (VTC) can help improve access to diagnostic and follow-up care in memory clinics. This study investigated the stability of performance on VTC assessment in relation to in-person assessment using a test-retest design and explored user experiences of VTC assessment.
Materials And Methods:
Thirty-one patients (62 ± 6.7 years, 45% female, 58% Subjective Cognitive Decline, 42% Mild Cognitive Impairment/dementia diagnosis) were included from the Amsterdam Dementia Cohort between August 2020 and February 2021. Patients underwent a face-to-face neuropsychological assessment followed by a VTC assessment using the same test protocol within 4 months. Reliability coefficients were calculated using intraclass correlation coefficients (ICC). For each test, the proportion of clinically relevant differences in performances between assessment modalities was calculated. User experiences of patients and neuropsychologists were assessed with questionnaires (User Satisfaction and Ease of use [USE] questionnaire and System Usability Scale [SUS]). Neuropsychologists also participated in a focus group.
Results:
ICC values were moderate to excellent (0.63-0.93) for all test measures in the total sample. On all tests, most patients did not show clinically relevant performance differences between modalities. Patients and neuropsychologists reported overall positive VTC system usability, although neuropsychologists indicated in the focus group that patients without cognitive impairment required less training for the system and were more independent.
Conclusion:
VTC assessment showed adequate to excellent test-retest reliability for a broad range of neuropsychological tests commonly used in practice. Assessment through VTC may be a user friendly method in the memory clinic, especially to monitor individuals at risk for future cognitive decline.
