Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The present study will adopt a non-blinded parallel-group randomized controlled trial design that involves a Laughter Yoga group (intervention) and a treatment-as-usual group (Control). It aims to determine the feasibility of using LY intervention on patients with Major depressive disorder (MDD), and also to evaluate the potential effect of the intervention on comorbid depression, anxiety and stress for these patients. It is hypothesized that, LY group, as compared to the TAU group, will have significantly lower symptoms of depression, anxiety and stress, but greater improvements in self-reported mental health/physical health-related quality of life immediately post intervention and at 3 months' follow-up.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

72 community dwelling people with co-morbid symptoms of depression, anxiety and stress who are diagnosed and treated for major depressive disorder (MDD) will be recruited into the study from the Community Psychiatric Service (CPS) of Castle Peak Hospital. After baseline measurements, 36 participants will be randomly allocated into the Laughter Yoga group (LY) or Treatment-as-usual group (TAU).

The LY intervention will be delivered by a certified lead LY trainer and monitored by three Co-Is and/or Research Assistants. The LY participants will be asked to attend a total of eight 45-minutes sessions of group-based laughter yoga over a 4 week period. TAU participants will receive their usual routine community mental health care.

All data collection will be conducted by a trained research assistant. Demographic data and all the relevant clinical/treatment data will be collected at baseline, whereas outcome data will be collected at three time points: Baseline, after the 4 weeks' intervention period, and at 3 months after finishing the intervention.

The level of depression, anxiety and stress will be the primary outcome of the study. They will be measured by the Chinese version of the Depression Anxiety Stress Scale (DASS-21) developed by Lovibond and Lovibond (1995) . The secondary outcome will be quality of life (physical and mental health related), which will be assessed with the short Form 12 item (version 2) Health Survey (SF12v2) (Lam et al., 2014). The Chinese language version of the client satisfaction questionnaire (CSQ-8)(Attkisson and Zwick, 1982; Attkisson, 2012) will be used to measure patient's view about their satisfaction with the LY intervention immediately post intervention. To explore patient's experience on the LY intervention, a sample of 12 patients who received the LY intervention will be invited to a short individual interview with the research assistant at three months' follow-up. Trial feasibility data, such as refusal rate, response rate, drop out, attendance rate will also be recorded throughout the study.

Descriptive statistics will be used to contextualize the demographic and clinical characteristics of the study population at baseline. The baseline variables will be compared between the groups so that potential confounders will be identified and where necessary adjusted for. For pre-test and post-test comparisons between the two groups, ANOVA test will be adopted if satisfactory normality of data is established. Otherwise, Kruskal-Wallis test will be used.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Laughter Yoga (LY) Group

The LY session will be offered twice weekly, for 45 minutes each time. Each participant will be asked to attend a total of 8 groups (over 4 weeks).

Group Type EXPERIMENTAL

Laughter Yoga

Intervention Type BEHAVIORAL

A LY group will be composed of 8-12 participants. Each sessions will include 4 essential elements steps of laughter yoga, laughter meditation and grounding exercises. The 4 steps of laughter yoga are 1) warm up exercise, 2) deep breathing exercises, 3) childlike playfulness and 4) laughter exercises. The laughter meditation is a deeper experience of unconditional laughter in which laughter often comes in natural waves and it becomes infectious and set off a chain reaction to infect other people. The grounding exercises allow individuals to ground the energy of laughter and relax. The LY intervention will be facilitated by a certified lead LY trainer.

Treatment-as-usual (TAU)

The TAU will receive their usual routine community mental health care (including medications) and attend medical outpatient appointments as determined by their individual needs.

Group Type NO_INTERVENTION
