BACKGROUND: Older adults are at high risk for developing serious somatic and psychological symptoms associated with COVID-19. Currently available instruments may not be sensitive to the concerns about COVID-19 in postacute and long-term care and their applications in telehealth remain to be clarified. OBJECTIVE: We investigated the psychometric properties of the Mood-5 Scale (M5) as a rapid self-assessment of the COVID-19 psychological burden among postacute and long-term care residents. METHODS: Residents (N=131), aged 50 years and above, from 20 postacute and long-term care facilities in Maryland, USA, were evaluated in-person or via telehealth (43/131, 32.8%) across a 4-week period (May 11 to June 5, 2020) during the COVID-19 pandemic. The COVID-19 psychological burden experienced by the residents was rated by geriatric psychologists who independently reviewed their clinical documentation. Psychometric analyses were performed on the M5 in relation to psychological tests, COVID-19 psychological burden, and diagnostic data collected during the evaluation. RESULTS: The M5 demonstrated acceptable internal consistency (Cronbach &#945;=.77). M5 scores were not confounded by demographic variables or telehealth administration (P>.08). Convergent validity for the M5 was established via positive associations with anxiety (r=0.56, P<.001) and depressive (r=0.49, P<.001) symptoms. An M5 cutoff score of 3 demonstrated strong sensitivity (0.92) and adequate specificity (0.75) for identifying COVID-19 psychological distress among postacute and long-term care residents (area under the curve of 0.89, positive predictive value=0.79, negative predictive value=0.91). CONCLUSIONS: The M5 is a reliable and valid tool for self-assessment of mood that can help identify postacute and long-term care residents with significant psychological burden associated with COVID-19. It can be completed in less than 1 minute and is appropriate for use in both in-person and virtual visits.
