N2 - PURPOSE: The Enhancing Recovery in Coronary Heart Disease Patients (ENRICHD) clinical trial was designed to test whether intervening on depression or low perceived social support reduces mortality and reinfarction in patients with acute myocardial infarction (MI). This report analyzes the effect of the intervention on quality of life (QOL), which was an important secondary outcome. METHODS: ENRICHD was a randomized controlled clinical trial comparing a psychosocial intervention based on cognitive behavioral therapy to usual medical care in 2,481 patients from 8 clinical centers. Patients with acute MI were included if they met criteria for depression, low perceived social support, or both. QOL was assessed at the 6-month clinic visit in the first 1,296 patients. QOL measures included the Medical Outcomes Study Short Form summary measures of physical functioning (SF12-PCS) and mental functioning (SF12-MCS), a Life Satisfaction Scale (LSS), and a measure of overall QOL based on the ladder of life (LOL) technique. RESULTS: There were significant treatment differences on the SF12-MCS (difference 2.2, 95% confidence interval [CI] 1.2-3.2), the LSS (difference 1.0, 95% CI 0.5-1.5), and the LOL (difference 0.3, 95% CI 0.1-0.6), but not on the SF12-PCS (difference 0.8; 95% CI = -0.5-2.0). Effect sizes for the intervention on QOL outcomes were modest. CONCLUSIONS: Psychosocial interventions of limited duration confer modest QOL benefits in post-MI patients who are depressed or have low perceived social support. Interventions of longer duration or greater intensity may be required to produce more substantial improvements in QOL in these patients.
