Effects of participatory organizational interventions on mental health and work performance: A protocol for systematic review and meta-analysis.

ABSTRACT

INTRODUCTION: Participatory organizational interventions to improve psychosocial working conditions are important for a safe and healthy work environment. However, there are few systematic reviews or meta-analyses investigating the effects of these interventions on workers' mental health and work-related outcomes. We apply the protocol for systematic review and meta-analysis to examine the effect of participatory organizational intervention on mental health and work performance. METHODS AND ANALYSIS: The participants, interventions, comparisons, and outcomes (PICO) of the studies in this systematic review and meta-analysis were defined as follows (P) inclusion of all workers, (I) participatory organizational intervention, (C) treatment as usual or no intervention (including waitlist control), and (O) mental health and work performance. Published studies will be searched using the following electronic databases PubMed, EMBASE, PsycINFO, PsycARTICLES, and Japan Medical Abstracts Society. Studies that (1) included participatory organizational intervention, (2) included participants who were working as of the baseline survey period, (3) assessed mental health or work performance outcomes, (4) used a cluster randomized controlled trials design, (5) were published in English or Japanese, and (6) were published in peer-reviewed journals (including advanced online publication) will be included. Study selection and the risk of bias assessment will be performed independently by two reviewers. A meta-analysis will be performed to statistically synthesize the included studies. Publication bias will be assessed for meta-bias using Egger's test as well as visually on a funnel plot. We will assess the heterogeneity by using the Q statistic.
