The Mood-5 (M5): A New Scale for Detecting COVID-19 Psychological Burden in Post-acute and Long-term Care Residents (Preprint)
BACKGROUND Older adults are at high risk for developing serious somatic and psychological symptoms from the 2019 novel coronavirus (COVID-19). Available instruments may not be sensitive to concerns about COVID-19 in post-acute and long-term care (PA/LTC) and have unknown utility for telehealth. OBJECTIVE We investigated the psychometric properties of the Mood-5 Scale (M5) as a rapid self-assessment of COVID-19 psychological burden in PA/LTC residents. METHODS Residents (N = 131, age ≥ 50) in 20 Maryland, USA PA/LTC settings were evaluated in-person or via telehealth (33%) during a four-week COVID-19 period (05/11/2020 – 06/05/2020). COVID psychological burden was rated by psychologists who independently reviewed 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 (???? = .77). M5 scores were not confounded by demographic variables or telehealth administration (ps > 0.08). Convergent validity for the M5 was established via positive associations with anxiety (r = 0.56, p < 0.001) and depressive (r = 0.49, p < 0.001) symptoms. A M5 cutoff of 3 demonstrated strong sensitivity (.92) and adequate specificity (.75) for identifying COVID-19 psychological distress in PA/LTC residents (AUC = .89, PPV = .79, NPV = .91). CONCLUSIONS The M5 is a reliable and valid mood self-assessment that can identify residents with significant psychological burden associated with COVID-19. It can be completed in less than one minute and is appropriate for in-person and virtual visits.
