Randomized Controlled Trial Multicenter Study
How a therapy-based quality improvement intervention for depression affected life events and psychological well-being over time: a 9-year longitudinal analysis.
Short-term quality improvement (QI) interventions for depression can improve long-term mental health but mechanisms are unknown. We hypothesized that 1 pathway for such health benefits was an indirect effect with QI reducing risk factors for depression such as stressful life events. ⋯ Depression QI programs that include resources for psychotherapy can reduce occurrence of life events, further protecting subsequent mental health. Implications for the design of QI programs and development of prevention interventions are discussed.
