title: A randomized trial of a depression self-care toolkit with or without lay telephone coaching for primary care patients with chronic physical conditions.
abstract: OBJECTIVE
  The aim of this study was to compare outcomes of use of a depression self-care toolkit with and without lay telephone coaching among primary care patients 40 years and older with depressive symptoms and comorbid chronic physical conditions.
  
  
  METHODS
  A single blind, individually randomized, pragmatic trial of a depression self-care toolkit (Toolkit) with or without lay telephone coaching was conducted among primary care adults with depressive symptoms and comorbid chronic physical conditions. Eligible patients were randomized to receive the Toolkit with (intervention) or without (control) telephone coaching provided by trained lay coaches. The primary outcome was depression severity [Patient Health Questionnaire (PHQ-9)] at 6 months. Secondary outcomes were self-efficacy, satisfaction, and use of health services at 6 months.
  
  
  RESULTS
  A total of 223 patients were randomized, and 172 (77.1%) completed 6-month follow-ups. PHQ-9 scores improved significantly in both groups over the 6-month follow-up; the differences in PHQ-9 scores between intervention and control groups were statistically significant at 3 months [effect size = 0.43; 95% confidence interval (CI) = 0.15-0.70] but not at 6 months (effect size = 0.23; 95% CI = -0.04-0.59). Patients with moderate depression severity (PHQ-9 10-19) and high self-efficacy at baseline were most likely to benefit from the intervention. There was no significant effect of the intervention on the secondary outcomes.
  
  
  CONCLUSIONS
  The incremental value of lay telephone coaching of a Toolkit appears short-lived. Targeting of coaching to those with moderate depression severity may be indicated.
