Group bright light therapy compared to treatment as usual for delayed sleep-wake phase disorder among patients in psychiatric care (the SIP trials): a protocol for a pragmatic, randomised controlled trial.

ABSTRACT:

Introduction

Circadian rhythm sleep-wake disturbances appear to be prevalent in psychiatric populations and may maintain and exacerbate psychiatric symptoms. Bright light therapy (BLT) is, in addition to exogenous melatonin, the treatment of choice for circadian rhythm disorders like delayed sleep-wake phase disorder (DSWPD) and has yielded promising results in patients with comorbid psychiatric illness. However, such patients are rarely offered this treatment in outpatient clinics. The aim of this randomised controlled trial is to investigate whether group BLT for psychiatric outpatients is superior to treatment as usual (TAU).
