Study 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.
