Healthcare professionals’ exposure to work-family conflict negatively affects the health and well-being of the whole family and organizational outcomes. Specified workplace interventions are lacking. Therefore, the aim of the study was to evaluate the feasibility of a two-day group-treatment specifically designed for the needs of healthcare professionals with family responsibilities concerning participation, satisfaction with the intervention and family- and individual-related outcome variables. 24 mostly female (85.7%) participants of a community hospital in southern Germany attended the treatment. Data were collected at baseline (T0), directly after the treatment (T1) and two months later (T2). A two-factor analysis of variance with repeated measures showed a statistically significant time x group effect for self-efficacy (F = 5.29, p = 0.011). Contrasts displayed substantial pre-post (T1-T0, T2-T0) increases of self-efficacy in the intervention group as compared with the control group. Non-parametric Mann-Whitney-U tests are in line with these findings. The results indicate that the group-treatment adapted to the needs of healthcare professionals has the potential to boost self-efficacy among healthcare professionals and that participants were predominantly satisfied. Perspectives for future research and practical implications are discussed in the light of the manifest lack of healthcare professionals
