  Purpose

Background: Common mental illness, such as anxiety disorders and depression, is the main cause for sick leave in Sweden. Cognitive behavior therapy (CBT) has been shown to be effective in alleviating target symptoms of these disorders, but its effect on sick leave rates has not been sufficiently addressed. The investigators have developed an intervention called return to work (RTW), which is based in cognitive behavioral theory, that has a primary aim of helping sick-listed patients with common mental illness return to work. This new treatment has not been evaluated in a randomized controlled trial.

Aims: The aim of this study is to investigate the effect of CBT and RTW for common mental illness in a randomized controlled trial conducted in primary care. Participants will be randomized to diagnosis specific CBT (n=70), RTW (n=70), or a combination of the two treatments (n=70). Main outcomes are days of sick leave and clinician severity rating of psychiatric symptoms. This study could contribute to new knowledge regarding how to best treat patients on sick leave with common mental illness.

Arms Assigned Interventions
Active Comparator: Cognitive Behavior Therapy
As the trial will include several different common mental disorders, the cognitive behavior therapy used in the study will be based on the protocols with best empirical support. Cognitive behavior therapy entails psychoeducational components, i.e. the patient is learns about the disorder and how to view it from a cognitive behavioral perspective. The most important part of the treatment is systematic behavior changes often targeted at exposure to feared stimuli. This is combined with cognitive interventions targeted at challenging negative automatic thoughts. All treatments will be delivered by licensed psychologists.

Experimental: Return to work
Participants randomized to this arm will receive an experimental treatment, based in cognitive behavioral therapy, with primary aim to help patients return to work. Interventions are aimed at solving work-related problems and comprises problem-solving training and systematic employer-patient meetings aimed at facilitating a gradual return to the workplace. Licensed psychologists deliver all treatments.

Experimental: CBT and Return to work
Participants randomized to this arm will receive a combination of cognitive behavior therapy and the return to work treatment. This arm is included in the study as the clinically most relevant therapy, would the return to work treatment be effective in reducing sick leave, is a treatment were patients are provided support to return to work but also is clinically effective in reducing psychiatric symptoms.
