Data from an RCT of IAPT Norway (?Prompt Mental Health Care? [PMHC]) were linked to several administrative registers up to five years following the intervention. The aims were to (1) examine the effects of PMHC compared to treatment-as-usual (TAU) on work-related outcomes and health care use, (2) estimate the cost?benefit of PMHC, and (3) examine whether clinical outcomes at six-month follow-up explained the effects of PMHC on work-/cost-benefit-related outcomes.
