Based on our review, we conclude that there is weak evidence to support the use of vocational interventions to improve work participation and limited evidence to reduce mental distress for the unemployed. We recommend further development and evaluation of return to work intervention strategies for unemployed individuals.

We conclude that the sick-listed unemployed workers with mental health problems have to deal with multiple problems, of which medical problems are only a part. These workers need help aimed at their coping methods according to one of the three types of workers' characteristics. Moreover, they need specific help organising and structuring their problems, getting their life back on track, and finding employment. Implications for Rehabilitation Unemployed workers with mental health problems face considerable challenges which impede their return to work. Evaluating the workers' attitude may provide useful information on their own return-to-work process. In many cases, workers indicate a need for coaching to help them with problem-solving, planning, gaining structure, getting their life back on track, and finding employment. Rehabilitation professionals should tailor RTW interventions to the needs of these workers, aimed at their specific problems and taking into account the workers' coping methods according to one of three types of workers' attitudes towards their own RTW process.
