Study Details

Study Description

Brief Summary

The investigators propose to investigate the efficacy of a brief (4-session) Body Scan (BS) meditation intervention for individuals with bipolar I disorder with insomnia (i.e. difficulties falling or staying asleep). The investigators will compare the Body Scan intervention with a 4-session brief supportive psychotherapy (SP) intervention. The investigators hypothesize that the Body Scan will improve objective sleep quantity and quality.

Detailed Description

This is the first evaluation of the efficacy of a mindfulness-based intervention for insomnia in bipolar disorder. It distills the findings from previous mindfulness-based interventions for other disorders that documented beneficial effects for sleep, by concentrating on the most active mindfulness ingredient for treating sleep (the Body Scan). To date, mindfulness based studies have focused on either subjective sleep reports or laboratory-based measures of sleep, both of which have long been called into question because of their lack of ecological validity. This study takes advantage of recent developments in ambulatory sleep monitoring by using the new, FDA approved M1 device, which assesses sleep objectively in a patient's home environment. The M1 device is also the only ambulatory sleep-monitoring device to date that simultaneously assesses both sleep quantity and quality. Finally, this study broadens the view above and beyond sleep and mood and investigates the impact on cognitive and sleep-related psychosocial functioning, both at the end of treatment as well as at a 3-month follow-up. Overall, this work could result in a brief, easy to administer, and easy to disseminate intervention for patients with bipolar disorder with insomnia.

Arms and Interventions

Arm	Intervention/Treatment
Active Comparator: Brief Supportive Psychotherapy (SP) 30 people will be randomized to receive Brief Supportive Psychotherapy.	Behavioral: Brief Supportive Psychotherapy (SP) SP is a common form of non-specific psychotherapy available to patients with bipolar disorder in the community. It focuses on addressing a patient's current concerns, supporting a patient's adaptive coping skills, improving self-esteem, and expressing feelings and the therapeutic alliance. Using a conversational style, SP involves conveying empathy, validation, comforting and supporting patients in coping with distress about current life issues as well as providing encouragement and praise, clarification and opportunity to vent. SP will match BS in length, number of sessions and delivery schedule (four, 60-minute sessions, week 1, 2, 4, 6).
Experimental: Body Scan (BS) Meditation Intervention 30 people will be randomized receive the Body Scan Meditation Intervention.	Behavioral: Body Scan (BS) Meditation Intervention This intervention consists of 4 individual 60-minute sessions (week 1, 2, 4, and 6) in which participants learn the body scan meditation exercise and practice it at home, daily, lying in bed at their usual bedtime after going to bed (and when waking up at night, unable to go back to sleep). The Body-Scan meditation consists of a 30-minute exercise during which participants are guided to focus their attention on certain parts of their body (e.g. toes, feet). The core skill involves gradually adopting an observant, non-judgmental, and accepting stance towards bodily sensations, including feelings and thoughts.

Outcome Measures

Primary Outcome Measures

Total Sleep Time (TST) [8 weeks]

Secondary Outcome Measures

Young Mania Rating Scale (YMRS) [20 weeks]
Young Mania Rating Scale is an 11-item, clinician-rated measure that assesses the presence and severity of patient's current symptoms of mania.
Hamilton Depression Rating Inventory (HAM-D 17). [20 weeks]
The HAM-D 17 is an established clinician-rated outcome measure in treatment trials for depression.
