We previously reported that an inpatient multimodal occupational rehabilitation program (I-MORE) was more effective in reducing sickness absence and facilitating return to work (RTW) at 12\u00a0months follow-up compared to an outpatient program that consisted mainly of Acceptance and Commitment Therapy (O-ACT). We now report the 2-year outcome data.\n                    <jats:italic>Methods<\/jats:italic>\n                    A randomized clinical trial with parallel groups. Participants were 18\u201360\u00a0years old, sick listed with musculoskeletal, common mental or general\/unspecified disorders. I-MORE lasted 3.5\u00a0weeks and consisted of ACT, physical training and work-related problem solving. O-ACT consisted mainly of 6 weekly sessions (2.5\u00a0h. each) of ACT in groups. Outcomes were cumulated number of days on medical benefits and time until sustainable RTW (1\u00a0month without medical benefits) during 2-years of follow-up, measured by registry data.\n                    <jats:italic>Results<\/jats:italic>\n                    For the 166 randomized participants, the median number of days on medical benefits was 159 (IQR 59\u2013342) for I-MORE vs 249\u00a0days (IQR 103\u2013379; Mann\u2013Whitney U test, p\u2009=\u20090.07), for O-ACT. At 2\u00a0years, 40% in I-MORE received long-term benefits (work assessment allowance) vs 51% in O-ACT. The crude hazard ratio (HR) for sustainable RTW was 1.59 (95% CI 1.04\u20132.42, p\u2009=\u20090.03) and the adjusted HR 1.77 (95% CI 1.14\u20132.75, p\u2009=\u20090.01), in favor of I-MORE.\n                    <jats:italic>Conclusions<\/jats:italic>\n                    The 2-year outcomes show that I-MORE had long-term positive effects on increasing work participation for individuals sick listed with musculoskeletal and mental disorders.
