Current Primary Outcome Measures  ICMJE
 (submitted: September 20, 2016)		 SIGH-ADS Depression Score [ Time Frame: 6 weeks ]
The Structured Interview Guide for the Hamilton Depression Rating Scale-HRS-D with Atypical Depression Supplement (SIGH-ADS) provides a benchmark for depression severity; SIGH-ADS scores range from 0-79; higher values represent increased depression severity and worse outcome.
Original Primary Outcome Measures  ICMJE
 (submitted: February 26, 2009)		 Continuous depression ratings on the Structured Interview Guide for the Hamilton Depression Scale with Atypical Depression Supplement (SIGH-ADS) instrument [ Time Frame: Weekly measures in the Acute Phase Weeks 1-6 ]
Change History
Current Secondary Outcome Measures  ICMJE
 (submitted: September 20, 2016)		 Global Assessment of Functioning (GAF) [ Time Frame: 6-weeks ]
The GAF is used to assess global psychosocial functioning. Scores range from 0-100 with higher values representing higher functioning and better outcome.

Official Title  ICMJE Efficacy of Light Therapy for Bipolar Depression: A Randomized Controlled Trial
Brief Summary The purpose of this study is to understand the efficacy of light therapy for bipolar depression.
Detailed Description Bipolar Disorders (BD) are associated with chronic depression, disability, and increased suicide risk. Building on earlier findings, we conducted a 6-week randomized, double-blind, placebo-controlled trial to investigate the efficacy of midday light therapy for bipolar depression. The aims were to examine the change in depression levels and the proportion of patients who responded and remitted. We assessed predictors of response with measures of side effects, sleep quality, suicidality, and psychosocial functioning. We included depressed adults with BD-Type I or II confirmed on the SCID interview and taking stable-dosed antimanic medication. We excluded patients with psychosis, rapid cycling, obsessive compulsive disorder, alcohol or substance use disorders, hypomania or mania, and severe suicidality. Patients were randomized to 7000 lux broad spectrum light therapy OR 50 lux dim red light for 45-60 minutes daily. Weekly, the blinded-clinician assessed symptoms with the Structured Interview Guide for the Hamilton Depression Scale with Atypical Depression Supplement (SIGH-ADS) and global functioning.
