Outcome Measures

Primary Outcomes (1)

  • 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.

    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

    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.
