Purpose

The purpose of this study is to test whether a dietary supplement (low-dose melatonin) commonly used to treat night owls, administered in conjunction with a behavioral sleep intervention, will help to shift the brain clock earlier and improve mood and sleep in bipolar disorder. Eligible participants will be randomized to receive melatonin plus a behavioral sleep intervention or placebo plus a behavioral sleep placebo. The hypotheses for this study include: - Melatonin plus behavioral sleep intervention (compared to placebo plus behavioral sleep placebo) will produce a greater advance of dim light melatonin onset (DLMO), between pre- and post-treatment. - Melatonin (compared to placebo) will produce a greater reduction in Patient Health Questionnaire-9 score between pre- and post-treatment.

Intervention Model Description
Participants that meet eligibility for the randomized trial are randomized using minimization in a 1:1 ratio to low-dose afternoon melatonin plus a behavioral sleep intervention (MEL) or placebo tablet plus behavioral sleep placebo (CTL) After the Randomized clinical trial portion, ten participants from the control group will be recruited to receive open label melatonin.

Arm Groups

ArmDescriptionAssigned Intervention
Experimental
Melatonin
Oral medication will be taken for 28 days on the afternoon or evening of the participants first intervention session and continue daily for the remainder of the treatment period.
  • Drug: Melatonin
    Participants randomized to this intervention will take 1 oral pill (0.5 milligrams (mg)) daily. They will attend 4 weekly behavioral sleep intervention sessions with a therapist. In addition, participants will complete questionnaires (MyDataHelp app), monitor sleep, collect saliva samples, and wear the Fitbit Device.
  • Behavioral: Behavioral sleep intervention
    An active intervention that is typically paired with melatonin to maximize treatment effects.
Placebo Comparator
Placebo
Oral medication will be taken for 28 days on the afternoon or evening of the participants first intervention session and continue daily for the remainder of the treatment period.
  • Other: Placebo
    Participants randomized to this intervention will take 1 oral placebo pill daily. They will attend 4 weekly behavioral sleep control sessions with a therapist. In addition, participants will complete questionnaires (MyDataHelp app), monitor sleep, collect saliva samples, and wear the Fitbit Device.
  • Behavioral: Behavioral sleep control
    A behavioral placebo (which does not improve sleep in delayed sleep-wake phase disorder) to control for social/interpersonal effects of behavioral sleep intervention sessions.
