The Effects of Light Therapy on Circadian Rhythms, Sleep, and Mood in Postpartum Depression
Abstract
The proposed study aims to establish the feasibility of light therapy for postpartum depression delivered via Re-Timer, demonstrate its preliminary efficacy, and illuminate relationships between circadian shifts and mood changes using a novel, home-based circadian biomarker assessment paradigm (salivary dim light melatonin onset; DLMO).
Conditions: Depression, Postpartum.
Primary outcome: Change From Baseline Score of the Hamilton Depression Rating Scale-Seasonal Affective Version (SIGH-SAD) at 5 Weeks; Change From Baseline Score of the Edinburgh Postnatal Depression Scale (EPDS) at 5 Weeks; Change From Baseline Time of Dim Light Melatonin Onset (DLMO) at 5 Weeks.
Enrollment: 10 participants.
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 10 participants or records.
