METHODS: To assess the sustainability of this interdisciplinary medical, behavior and educational training program, the intervention group (IG, N=215) and a control group (CG, Industrial worker with OSD who solely received dermatological treatment, N=85) were followed up 9 month and 2 years after their individual project participation by a standardized questionnaire. A subcohort of the intervention group (IG(2007,) During the study period, there was no change in job stress (JCQ) or effort-reward imbalance (ERI). Compared to baseline, in both intervention groups there was significant decrease in stress level (PSS10, WFC), a reduction in symptom scores (STAIT, PHQ15) and an increase in well being (WWB5, LM). Overcommitment decreased only in the long intervention group. Employees working in the human sector (teachers, social workers, health care providers) benefited more, than industrial workers or those working in law enforcement. Our results confirm the benefits of the stress management interventions at the workplace. The short, 4 lesson program was found nearly as effective as the longer 16 lesson one. These results suggest the feasibility of short interventions, and the importance of focusing on overcommitment, a key factor in work-related stress. Further analysis are needed to clarify the magnitude of the beneficial effects in connection with personal and work stress characteristics of the participants.
