Trial Outcomes & Findings for Light Therapy for Bipolar Disorder. Efficacy of Light Therapy for Bipolar Depression: A Randomized Controlled Trial (NCT NCT00852592)

NCT ID: NCT00852592

Last Updated: 2016-11-07

Results Overview

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.
