Brief summary

This project is based on the biphasic instability model and social timing theory, utilizing IPSRT to help regulate social interactions and establish regular daily habits, alleviate emotional symptoms, and prevent. The included patients with bipolar II disorder who did not take medication for the first time or relapsed within the past month were randomly divided into a medication only group (Q group), a only IPSRT group (I group). Group Q received treatment with quetiapine alone (starting at 50mg/day, with an additional 50mg to 300mg/day per week, and the dosage can be flexibly adjusted); Group I received 12 weeks of interpersonal and social rhythm therapy (12 sessions, once a week, 40 minutes each time, with relatively fixed tasks and agendas for each meeting). Compare the changes in various clinical evaluation scales and skin potential before and after treatment, explore the safety and effectiveness of drug therapy and psychotherapy for patients with bipolar II disorder with rhythm disorders, and investigate the potential biological mechanism of IPSRT by collecting data on salivary cortisol and melatonin, peripheral circadian rhythm genes (PER1/PER2/PER3/BMAL1), and magnetic resonance.

Interventions

Patients received treatment with quetiapine alone (starting at 50mg/day, with an additional 50mg to 300mg/day per week, and the dosage can be flexibly adjusted)

Patients received 12 weeks of interpersonal and social rhythm therapy (12 sessions, once a week, 40 minutes each time, with relatively fixed tasks and agendas for each meeting)

Design outcomes

Primary

MeasureTime frameDescription
Hamilton Depression Scale (17-items) Total Score ChangeBaseline,4,8,12 weeks after treatmentThe Hamilton Depression Scale (17-items), is a 17 item diagnostic questionnaire used to measure the severity of depressive episodes in patients with mood disorders. It's considered the gold standard for rating depression severity and used frequently in clinical trials. Higher HAM-D17 score indicates more severe depression. A reduction of 50% or more in total score from Baseline indicates clinical response.

Secondary

MeasureTime frameDescription
Change of The Biological Rhythms Interview of Assessment in Neuropsychiatry (BRIAN) scoreBaseline,4,8,12 weeks after treatmentThe BRIAN comprises 18 items, which are divided in 3 areas: sleep and social rhythms, activities and eating pattern. The total score ranged from 18 to 72, a higher score suggested a more severe biological rhythm disturbance.
NeuroimagingBaseline,12 weeks after treatmentMRI
Skin potentialBaseline,12 weeks after treatmentIn a quiet environment, the subject's left hand was pre connected to a portable skin potential acquisition device to collect skin potential signals under different types of emotional stimulation task paradigms. After denoising, 10 time-domain eigenvalues and 8 time-frequency domain eigenvalues were obtained for each task.
PolysomnographyBaseline,12 weeks after treatmentovernight polysomnography
Change of the Brief Social Rhythm Scale (BSRS) scoreBaseline,4,8,12 weeks after treatmentThe BSRS assess the irregularity with which participants engage in basic daily activities during the workweek and on the weekend, using a scale ranging from 1 (very regularly) to 6 (very irregularly)
Neuropsychological testsBaseline,12 weeks after treatmentSoftware testing (Prisoner's Dilemma game, Social searching task)
Change of Beck Scale of Suicidal Ideation scoreBaseline,4,8,12 weeks after treatmentBeck Scale of Suicidal Ideation is a 21-item self-report instrument that detects and measures the intensity of a patient's specific attitudes, behaviors, and suicide plans during the past week. The BSI score ranges from 0 to 63, with higher scores indicating worse outcomes and lower scores indicating better outcomes.
Change of the Pittsburgh Sleep Quality Index (PSQI) scoreBaseline,4,8,12 weeks after treatmentThe PSQI is a validated self-report questionnaire assessing sleep quality and disturbance over 1 month, quantifying 7 sleep-related domains, with higher scores indicating worse sleep quality.
Change of the Young Mania Rating Scale (YMRS) scoreBaseline,4,8,12 weeks after treatmentThe Young Mania Rating Scale (YMRS) , is a 11 item diagnostic questionnaire used to measure the severity of mania symptom in patients with mood disorders.
Change of Hamilton Anxiety Scale scoreBaseline,4,8,12 weeks after treatmentHamilton Anxiety Scale is a 17 item diagnostic questionnaire used to measure the severity of anxiety episodes in patients. Each item on the scale is rated on a 5-point scale from 0 (not present) to 4 (severe), with the total score ranging from 0 to 68. The HAMA-17 is often used in clinical and research settings to assess the severity of anxiety symptoms and to evaluate the effectiveness of treatments for anxiety.
Change of the Sociaty Adaptive Scale scoreBaseline,4,8,12 weeks after treatmentSAS is a self-rating scale used to assess an individual's social functioning in areas such as work, study, interpersonal communication, and family life.
bloodBaseline,12 weeks after treatmentBlood samples are collected to analyze the expression levels of peripheral circadian clock genes (PER1/PER2/PER3/BMAL1).
saliva samplesBaseline,12 weeks after treatmentSaliva is employed for the analysis of cortisol and melatonin
