Previous research yields inconsistent findings on the effect of telecommuting on health and little knowledge on its explanatory mechanisms. In reply, this study investigated work-home interference, home-work interference and social support from colleagues as explanations (mediators) of the relationship between the extent of telecommuting and psychological distress. We collected 4-wave data during the first wave of the COVID-19 pandemic (April-June 2020) from 5,959 Belgian workers. Using Random Intercept Cross-Lagged Panel Modeling, we investigated within-person processes over time. Results showed that telecommuting predicted work-home interference and social support, with these effects varying by pandemic stage. Also, the effects of the mediators on psychological distress varied over time. No indirect effects from telecommuting to psychological distress via the mediators were found. Our findings suggest that the context presents certain challenges to teleworkers that may make telecommuting demanding in terms of home-work interference and social support, implying the need for tailored support.
