CI: Confidence interval; SMD: Standardised Mean Difference

Intervention description:

In two studies, an occupational therapy program focusing on work reintegration, combining modified work and supportive interventions was added to clinical care. In one study a regular Employee Assistance program was expanded and incorporated work coaching and modification.

CAU: Care As Usual; CI: Confidence interval; SMD: Standardised Mean Difference

Intervention description

Enhanced primary care

General practitioners were enrolled in a quality improvement program and were expected to provide enhanced care including antidepressant medication and psychological interventions, according to primary care guidelines.

Telephone outreach and care management

This program systematically assessed needs for treatment, facilitated entry into in‐person treatment (both psychotherapy and antidepressant medication), monitored and supported treatment adherence, and (for those declining in‐person treatment) provided a structured psychotherapy intervention by telephone.
