Laughter-inducing Interventions for Workplace Stress Management: A Scoping Review.

Background: Mental health at work is a public health priority. Previous studies in the general population suggest that laughter-inducing interventions may support mental health. Their workplace potential warrants a scoping review. The aim of this study was to document, in the literature, the components and effectiveness of laughter-inducing interventions in the workplace. Methods: A structured search strategy was applied to 6 databases. Studies assessing laughter-inducing interventions among workers using interventional designs were included. Two reviewers independently screened and extracted data and appraised studies using the Mixed-Methods Appraisal Tool. Thematic analysis was performed to answer the research questions. Results: Out of the 613 records identified, twenty-five studies were included with samples of varying sizes ( Conclusion: While findings suggest that laughter-inducing interventions may be promising for reducing workplace stress, most included studies were of poor methodological quality, warranting cautious interpretation. Further research is needed due to methodological heterogeneity and limitations.
