Anna Finnes2 Sickness absence due to mental disorders Mental disorders are among the leading causes of disability Especially among people in working ages Most common diagnosis Adjustment disorders Depression Long sickness absence spells
Treatment options? Cognitive behavioral Therapy (CBT) Not effective with regard to sickness absence/RTW Acceptance and Commitment Therapy (ACT) Third wave behavior therapy Seeks the construction of broad, flexible behavior repertoires Workplace interventions (WI) Moderate quality evidence (Cochrane, 2009) for muskuloskeletal pain No evidence for mental disorders Combining clinical interventions with workplace interventions Reduce both clinical symptoms and sickness absence?

Efficacy of Acceptance and Commitment Therapy and a Workplace oriented intervention on RTW The overall objective of the present study was to evaluate the efficacy of ACT and a WI, separately and in combination, in comparison to TAU. RCT Anna Finnes4

Net Sickness absence days PRE - POST No overall difference between groups over time F(3,1720)=1.272, p=.282) All groups improved over time F(1,1720)=43.285, p<.001) No differences between groups F(3,1720)=.273, p=.845) Follow-up No interaction effect All groups improved over time No differences between groups None of the intervention groups outperformed TAU Anna Finnes9
