Abstract

Objectives: We examined the feasibility and acceptability of a portable bright light intervention and its impact on sleep disturbance and depressive symptoms in older adults. Methods: One-arm prevention intervention pilot study of the Re-Timer (Re-Timer Pty Ltd, Adelaide, Australia) bright light device (worn 30 minutes daily for 2 weeks) in 1 older adults (age 65 + years) with subsyndromal symptoms of depression and poor sleep quality. Participants were assessed on intervention acceptability and adherence, depressive symptoms (Patient Health Questionnaire- 9), and sleep (Pittsburgh Sleep Quality Index, Insomnia Severity Index, actigraphy and daily diary reports). Results: The Re-Timer device was rated positively by participants, and, on average, participants only missed 1 day of utilization. Although depressive symptoms declined and self-reported sleep improved, improvement was seen largely before the start of intervention. Conclusions: An effective preventive intervention that is targeted towards a high risk group of older adults has the potential to reduce distress and costly health service use.
