What is being measured
The primary outcome is the main question the study is designed to answer.
Well-being
Adult well-being will be assessed using the WHO5 Wellbeing Index (WBI)
The WHO5 WBI is scored by summing the responses to five questions, each using a 6-point Likert scale (0-5). This derives a raw score between 0 and 25. This raw score is then multiplied by 4 to calculate a percentage score with a range of 0-100, where 0 represents the worst possible well-being and 100 represents the best.
Measured: Well-being will be assessed at baseline (start of study) and will be reassessed on day six (one day after the five-day intervention). The final score range is 0-100 where 0 represents the worse possible well-being and 100 represents the best.
Secondary outcomes (1)
Subjective mood status
Subjective mood status before and after each online video is viewed will be assessed using the EmojiGrid. The EmojiGrid is administered before and after viewing each video on each day of the five-day intervention (intervention group participants only).
EmojiGrid has 17 emojis in total and is divided into four sets with five emojis each. In our study, set (A) was used with the question, "Using the emoji below, indicate how you feel right now." In addition, the researcher added a number to each emoji to help participants select the emoji that represented them at the time asked. The score ranges from 1-5, where higher numbers indicate happier mood states and lower numbers suggest lower mood, with 3 representing a neutral mood.
Measured: The EmojiGrid is administered immediately before and after viewing each laughter video on each day of the five-day intervention. Subjective mood status is assessed on day 1, 2, 3, 4, and 5 of the intervention both pre and post video viewing.
