Feasibility Pilot in Preparation for Large Pragmatic Encouragement Trial of Bright Light Therapy (BLT) for Depression

Kaiser Permanente·interventional·Posted May 2, 2022·Updated Jun 6, 2025

In Brief

A clinical study evaluating Written Educational Material on BLT and Enhanced BLT Encouragement and Adherence Promotion for Depression. Completed, enrolled 92 participants across 1 site.

Detailed Summary

The Bright Start study is a randomized trial to compare three approaches, or "arms", for delivering Bright Light Therapy (BLT) to real-world patients. Arm 1 participants will receive Kaiser Permanente (KP) treatment as usual (TAU) with no BLT assistance. Arm 2 participants will receive brief written educational material on BLT but no phone coaching. Arm 3 participants will receive written educational material and phone coaching assistance for BLT initiation and adherence. This pilot will prepare for a future, fully powered effectiveness trial and is not powered for hypothesis testing. Therefore, the investigators do not expect between-condition comparisons to yield significant differences. The investigators will conduct analyses similar to those that would be used in a subsequent fully powered trial of the same design. These pilot study analyses posit that (a) Arms 2+3 are superior to Arm 1 in PHQ-9 continuous depression response; and (b) Arm 3 is superior to Arm 2 in PHQ-9 continuous depression response. The investigators will also conduct exploratory analyses to prepare for a future fully powered trial.

Interventions

Written Educational Material on BLTbehavioral

Participants in both Arms 2 and 3 will receive written information about how to obtain the greatest BLT benefit, including recommended day/time usage, session duration, eye distance from light box, the length of time to continue using, and the small risk of emergent mania or BD and how to recognize this. Written best practices for ideal BLT will be provided in both Arms 2 and 3 via secure EHR message, email, and/or USPS. PDFs of best practices for BLT will also be available for download on our study website.

Enhanced BLT Encouragement and Adherence Promotionbehavioral

BLT phone coaches will follow a four-step approach in engaging with Arm 3 participants: (a) provide encouragement to consider using BLT; (b) provide guidance regarding light box purchase and assist with obtaining compensation for purchase; (c) educate participants about ideal BLT use to obtain maximum benefit; and (d) provide ongoing brief telephonic adherence promotion and motivational interviewing (MI) where warranted to maximize persistent and appropriate BLT use.
