Official title

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

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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.
