Relief of Chronic or Resistant Depression (Re-ChORD): A pragmatic, randomized, open-treatment trial of an integrative program intervention for chronic depression

Background: c depression is a particularly disabling mood disorder and treatment outcomes are poor with either psychotherapy or pharmacotherapy alone. There is growing evidence that an integrative treatment approach may be optimal. A novel multi-modal, multi-disciplinary treatment program, Re-ChORD, was developed at the University of British Columbia and evaluated in this pilot study. s: RD consisted of guidelines-based medication management, and group-based interpersonal psychotherapy and occupational therapy. A randomized, parallel-groups, open-treatment trial was conducted comparing Re-ChORD to treatment as usual (TAU). Inclusion criteria were current depression (17-item Ham-D ≥ 15) and a diagnosis of a chronic depressive disorder. The primary outcome variable was clinical remission (17-item Ham-D ≤ 7) at 4 month assessment. s: l of 64 patients were randomised to Re-ChORD (N = 34) and TAU (N = 30). Under both intention to treat (ITT) and completer analyses, the remission rate was significantly higher in the Re-ChORD than TAU groups. Treatment effect size for remission was of medium magnitude (22.2% and 29.6% over TAU under ITT and completer analyses). tions: not collect sufficient follow-up data to investigate maintenance of gains. Re-ChORD shares elements with other combined treatments, and the present positive findings cannot be interpreted as being specific to the Re-ChORD program. sions: tent with growing evidence that integrative treatments are necessary for chronic depressive disorders, Re-ChORD was demonstrated in this pilot study to produce significantly greater rates of remission than treatment as usual. A larger-scale trial is warranted.
