Clinical Trial 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.
Description:
The most common treatments for depression are antidepressant medications (ADs) and
psychotherapies such as cognitive behavioral therapy (CBT). However, these treatments yield
only moderate benefits under ideal circumstances. These effects are further eroded when real
world patients initiate treatments at low rates and have poor adherence or early
discontinuation. This represents a depression care gap that supports the development and
promotion of other interventions. One of these alternative treatments, bright light therapy
(BLT), has established efficacy for seasonal affective disorder (SAD) and non-SAD depression,
is relatively low cost, and has few adverse effects-but is often overlooked and has little
presence in routine clinical care.
This R34 pilot study is in preparation for a subsequent large, pragmatic trial to examine the
effectiveness of bright light therapy (BLT) for depression when delivered to real-world
patients with little "scaffolding" typical of highly controlled efficacy trials. The
investigators will conduct a feasibility pilot with a sample of 90 patients selected with a
new clinical diagnosis of unipolar depression or SAD and PHQ-9 score >= 10, recorded in the
health plan's electronic health record (EHR). Participants will be randomized to one of three
arms:
- Arm 1 Treatment as Usual (TAU): A "usual care services" control group (e.g., ADs,
psychotherapy; all TAU is permitted and will be recorded for all participants in all
conditions);
- Arm 2 TAU + Minimal BLT Encouragement: TAU plus two minimal written communications
(mailed letter, secure EHR message, or email) promoting BLT as a promising treatment and
outlining steps for patients to self-initiate; Arm 2 will not include any phone coaching
or adherence promotion;
- Arm 3 TAU + Enhanced BLT Encouragement + Adherence Promotion: TAU plus 2-4 brief calls
to encourage BLT use, advise on purchase of a light box (LB), assist with obtaining
compensation for LB purchase, educate for correct LB use, and provide motivational
interviewing (MI) as needed to promote adherence.
The primary outcome is PHQ-9 self-reported depression symptoms; the primary test of BLT
effectiveness is the contrast between Arms 2+3 vs. Arm 1. This underpowered pilot study is
not powered for hypothesis testing. Therefore, the investigators do not expect
between-condition comparisons to yield significant differences. Nonetheless, as part of this
pilot the investigators will conduct analyses similar to those that would be used in the
planned, 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
conduct exploratory analyses to prepare for a future fully powered trial. The investigators
will examine other secondary outcomes including anxiety, disability, and mood seasonality,
and other secondary contrasts; e.g., Arm 2 vs Arm 3. The investigators will also examine
moderation effects; variation of BLT effects in subgroups (e.g., those receiving vs. not
receiving TAU antidepressants); and the investigators will examine mechanisms of BLT and MI
intervention effects via candidate mediators including normalized circadian rhythm, improved
sleep, and increased physical activity (for BLT), and readiness for change (for MI). This
pilot will yield feasibility products to assist with successful conduct of a subsequent full
trial: estimates of recruitment success, participant retention, and adherence with BLT
protocol; refinement of the adherence promotion protocol; and an estimate (with wide
confidence intervals) of BLT effectiveness.
