Aging Well Clinical Trial
Official title:
Feasibility and Effects of Laughter-imitation Therapy (LIT) in Promoting Mental Wellbeing Among Institutional Older Adults
Background: The mental wellbeing of the institutional population has to be promoted, particularly after the serious hit by the pandemic. Objectives: 1. To develop a LIT intervention to promote mental wellbeing of institutional older adults 2. To explore the feasibility and acceptability of such intervention; 3. To explore the potential effect of the intervention Design and subject: A pilot cluster randomized control trial will be conducted. The target population is institutional older adults. About 30 participants will be recruited from 2 nursing homes. The intervention is one-month imitated laughter practice. Each practice session lasts for 3 minutes once a day, giving a total of 21 minutes per week and the waitlist control group will be under usual care for the first 8 weeks. Then, they will start intervention after the 8 week, and receive two additional outcome assessments. A brief one-to-one training will be offered and a trained research assistant (RA1). Further in-person demonstration and return demonstration will be conducted until participant is able to demonstrate the Duchenne smile on their own. RA1 will be on-site for two days in the first week and one day in the second week to support the participants. At the end of the intervention, qualitative feedback will be collected from purposive sample until data saturation. Instruments: Chinese version including the World Health Organization Five Well-Being Index (WHO-5), 4-item Subjective Happiness Scale (SHS), Geriatric Depression Scale (GDS), Pittsburgh Sleep Quality Index (PSQI), 5-min Montreal Cognitive Assessment, FRAIL scale, Geriatric Adverse Life Events Scale (GALES). Main outcome measures: Feasibility and acceptability of laughter-imitation therapy (LIT) Data analysis: Descriptive statistics will be calculated for participants' characteristics, practice frequency, satisfaction, and health outcomes. Linear mixed-effects models will be used to evaluate health outcomes. Content analysis will be conducted for qualitative feedback. Expected results: The intervention is expected to be feasible and acceptable to institutional older adults as a means for promoting mental wellbeing, and potential beneficial effects will be demonstrated.

Primary | Participation rate of laughter-imitation therapy (LIT) | To reflect feasibility, the participation rate, calculated by dividing the number of participants joining the study by the number of participants invited, will be calculated. | 16 weeks after baseline | |
Primary | Compliance rate of laughter-imitation therapy (LIT) | To calculate the compliance rate, the number of practiced session divided by the number of scheduled session will be estimated. The participants will use a log book (Appendix V) to record their daily practice of self-induced laughter. | 16 weeks after baseline | |
Primary | Acceptance of laughter-imitation therapy (LIT) | To measure acceptance, level of satisfaction with the intervention will be collected by a single question with five point likert scale. | 16 weeks after baseline | |
Secondary | Change from baseline mental wellbeing at 4 weeks | Measured by the Chinese version of the World Health Organization Five Well-Being Index (WHO-5). WHO-5 consists of five statements on their mental wellbeing in the past two weeks, using a score from 0 (no time) to 5 (all of the time). The total raw score is multiplied by 4 to give the final score which ranges from 0 to 100, higher score indicates better well-being. | 4 weeks after baseline | |
Secondary | Change from baseline mental wellbeing at 8 weeks | Measured by the Chinese version of the World Health Organization Five Well-Being Index (WHO-5). WHO-5 consists of five statements on their mental wellbeing in the past two weeks, using a score from 0 (no time) to 5 (all of the time). The total raw score is multiplied by 4 to give the final score which ranges from 0 to 100, higher score indicates better well-being. | 8 weeks after baseline | |
Secondary | Change from baseline mental wellbeing at 12 weeks | Measured by the Chinese version of the World Health Organization Five Well-Being Index (WHO-5). WHO-5 consists of five statements on their mental wellbeing in the past two weeks, using a score from 0 (no time) to 5 (all of the time). The total raw score is multiplied by 4 to give the final score which ranges from 0 to 100, higher score indicates better well-being. | 12 weeks after baseline | |
Secondary | Change from baseline mental wellbeing at 16 weeks | Measured by the Chinese version of the World Health Organization Five Well-Being Index (WHO-5).

The total raw score is multiplied by 4 to give the final score which ranges from 0 to 100, higher score indicates better well-being. | 16 weeks after baseline | |
Secondary | Change from baseline subjective happiness at 4 weeks | Measured by the Chinese version of the 4-item Subjective Happiness Scale (SHS). Participants will respond on a 7-point Likert scale. The score is the average of the four items, and ranges from 1 to 7; a higher score indicates a higher happiness level. | 4 weeks after baseline | |
Secondary | Change from baseline subjective happiness at 8 weeks | Measured by the Chinese version of the 4-item Subjective Happiness Scale (SHS). Participants will respond on a 7-point Likert scale. The score is the average of the four items, and ranges from 1 to 7; a higher score indicates a higher happiness level. | 8 weeks after baseline | |
