Summary:
The sleep-wake cycle is severely disrupted during an episode of mania. Often mania is treated with medications that can come with significant side effects. Years of patient and family engagement with this population have revealed great interest in therapies targeting the sleep-wake cycle. However, there is still a lack of studies to support using these treatments for mania. Patient partners are especially interested in two specific therapies for mania, blue-blocking glasses and time-restricted eating, because of their perceived feasibility and safety. This pilot study will formally investigate the feasibility and effectiveness of these therapies for participants with mania, an understudied population that faces many difficulties even after recovery. The pilot study will collect interviews to identify barriers and ways to better support patients with mania using the therapies. The study will also investigate how well these therapies can treat manic symptoms and restore sleep-wake cycles by tracking symptom rating scales and measuring activity levels. Results from this pilot will be used to direct a larger study that will use a state-of-the art design to test the effectiveness of both therapies alone and in combination.

Primary Outcome Measures: Feasibility of Time-Restricted Eating: 1) Study Participation, Feasibility of time restricted eating for inpatients with mania as assessed by study participation, defined as the ratio of patients who consent to participate in the study after being approached by the research team. This will be reported as a ratio with the number of participants who consented as the numerator and the total number of patients approached for participation in the study as the denominator., Over the lifetime of the study starting at the first patient approached until recruitment is stopped.|Feasibility of Time-Restricted Eating: 2) Adherence to Protocol, Feasibility of time restricted eating for inpatients with mania as assessed by self-reported and observed adherence. At each study visit, the research team will consider the participants' self-report, notes in the medical record, and their own observations to select a rating on a Likert scale indicating how closely the participant has adhered to the schedule of their assigned intervention(s): a) Fully adherent; b) Almost fully adherent; c) Mostly adherent; d) Half adherent; e) Mostly non-adherent; f) Barely adherent; g) Not adherent., Baseline to Week 2 or until discharge, whichever comes first|Feasibility of Time-Restricted Eating: 3) Qualitative Interviews, Feasibility of time restricted eating for inpatients with mania as assessed by qualitative semi-structured interview. The research team will conduct a semi-structured interview with participants to elicit their perspective on the feasibility of time restricted eating in the context of an inpatient research study., One interview prior to the participant's discharge, at the end of their participation in the study.
Secondary Outcome Measures: Change in the Young Mania Rating Scale, The Young Mania Rating Scale is used to evaluate the severity of manic symptoms at baseline and over time in individuals with mania. It is an 11-item scale and total score ranges from 0 to 60 where higher scores indicate more severe mania, thus, a negative change (or decrease) from baseline indicates a reduction (or improvement) in manic symptoms. Total score ≤12 indicates remission (13-19=minimal symptoms; 20-25=mild mania, 26-37=moderate mania, 38-60=severe mania)., Baseline to Week 2 or until discharge, whichever comes first|Change in Montgomery-Åsberg Depression Rating Scale (MADRS) score, The Montgomery-Åsberg Depression Rating Scale is a clinician-rated depression scale used to assess depression symptom severity. It consists of 10 scored items, each scaled from 0 to 6 and the entire form totaling 0 to 60. The higher the score, the more severe the symptoms. A total score of 0-8 = remission/symptoms absent; 9-17 = mild depression; 18-34 = moderate depression; 35-60 = severe depression, Baseline to Week 2 or until discharge, whichever comes first|Change in the General Anxiety Disorder Questionnaire- 7-Item Measuring Severity of Anxiety Symptoms (GAD-7), Self-reported measurement of the severity of anxiety symptoms experienced within the last two weeks. It consists of 7 scored items and one follow-up question. Each of the 7 scored items generates a value from 0 (not at all) to 3 (nearly every day), yielding a total score ranging from 0 to 21, with higher scores indicating more severe symptoms of anxiety. These scores are interpreted in the following manner: a score of 0-4 indicates little or no anxiety, a score of 5-9 indicates mild anxiety, a score of 10-14 indicates moderate anxiety, and a score of 15-21 indicates severe anxiety. Generally, a score of 10 or above is considered to be a clinical cutoff implying that the respondent may be suffering from a general anxiety disorder., Baseline to Week 2 or until discharge, whichever comes first|Change in The Morning Evening Questionnaire - 19-Item Self-Assessment Questionnaire for Sleep Rhythms, Habits and Fatigue (MEQ), This questionnaire has 19 questions, each with a number of points. Scores can range from 16-86. Scores of 41 and below indicate "evening types." Scores of 59 and above indicate "morning types." Scores between 42-58 indicate "intermediate types.", Baseline; Week 1; Week 2 or until discharge, whichever comes first|Change in The Pittsburgh Sleep Quality Index - 18-Item Self-Assessment to Evaluate Sleep Quality (PSQI), The Pittsburg Sleep Quality Index Questionnaire is self-administered questionnaire designed to evaluate sleep quality consisting of 18 items that in turn are comprised of seven components, which include subjective sleep quality, sleep duration, sleep onset, habitual sleep efficiency, sleep disturbances, use of sleeping medications and daytime dysfunction. Each weighted equally on a 0-3 scale to be summed to yield a global PSQI score, which ranges between 0 and 21, where the higher the scores, the worse the sleep quality., Baseline; Week 1; Week 2 or until discharge, whichever comes first|Change in Circadian Rhythms: 1) Actigraphy, Wrist actigraphy data that captures the participant's activity level and their exposure to ambient light. The participant will wear the device continuously for one week. The research team will compare the data from different days to assess any changes in activity or light exposure., One week of continuous wearing starting at the Baseline visit.|Change in Circadian Rhythms: 2) Heart Rate, Heart rate monitors will be used to capture data from two different 24-hour periods one week apart. The research team will compare the two time periods for each participant to determine if there are changes., Two 24-hour periods: one starting at the Baseline visit and the other starting at the Week 1 visit.|Change in Circadian Rhythms: 3) Body Temperature, Body temperature monitoring using a device attached to the skin of the abdomen near the navel. The device will capture temperature data for two 24-hour periods one week apart. The research team will compare the two time periods for each participant to determine if there are changes., Two 24-hour periods: one starting at the Baseline visit and the other starting at the Week 1 visit.
