Objective:Small-to-medium enterprises (SMEs) require specialized attention regarding workplace mental health (WMH), but can be challenging to engage in WMH promotion interventions. This cross-sectional study analyzed self-reported motivations of SME owner/managers who engaged in a WMH promotion intervention specifically designed for SMEs.

Methods:Data from 297 SME owner/managers was thematically coded prior to conductingmultinominal logistical regression analyses to determine reasons for engagement based on a series of predictors, including owner/manager psychological distress, recent experience of a stressful work event, and business confidence.

Results:Owner/manager psychological distress, experience of a recent stressful workplace, and low 12-month business confidence incident were important predictors of engagement.

Conclusions:The findings provide important insights into the uptake of a WMH promotion intervention, which can inform the design and future recruitment strategies for WMH promotion interventions within the SME sector.
