Interventions: what works, what doesn't?

This review examines the evidence for the effectiveness of occupational stress interventions. Three types of interventions are considered: psychotherapy and counselling services, stress management training, and organizational level interventions. The review concludes that there is good evidence that, for specific mental health problems, formal psychotherapy is effective in terms of reducing individual symptoms. Other forms of intervention have been less well evaluated. The evidence that exists indicates that counselling services and stress management training have modest but short-term effects on individual well-being. Organizational interventions have insignificant effects on individual well-being and on organizational outcomes.
