Abstract
OBJECTIVES: Sleep and circadian problems are prevalent among midlife and older adults. Unfortunately, treatments for these problems are limited by poor memory for treatment. METHODS: We conducted a pilot trial of the Transdiagnostic Intervention for Sleep and Circadian Dysfunction paired with the Memory Support Intervention (TSC+MSI) for midlife and older adults with sleep and circadian problems (N = 26) (preregistration NCT04373538). After treatment, patients were offered optional booster messages. Aims were to (1) test change in clinical outcomes after TSC+MSI, (2) assess perceptions of TSC+MSI, and (3) evaluate patient engagement, preferences, and preliminary outcomes of booster messages. RESULTS: Following TSC+MSI, patients significantly improved on sleep disruption, sleep-related impairment, functional impairment, and select sleep diary outcomes. Therapist use of memory support strategies moderated improvements in sleep-related and overall impairment. TSC+MSI was perceived as acceptable by patients and feasible by therapists. Most patients opted in to the boosters. Sleep-related impairment significantly improved from pre-booster to post-booster. CONCLUSIONS: Following TSC+MSI and boosters, improvements were observed in clinical outcomes, and signals supported feasibility and acceptability. CLINICAL IMPLICATIONS: Although comparisons with control conditions and larger samples are needed, TSC+MSI and booster messages may improve sleep and circadian and related outcomes among midlife and older adults.
