Fernando L. Vázquez González et al., « A brief problem-solving indicated-prevention intervention for prevention of depression in nonprofessional caregivers », Psicothema, ID : 10670/1.s6d7ya
"Background: Despite depression being a common problem among nonprofessional caregivers, no studies of prevention of depression targeting this population exist in the literature. The studies of indicated prevention of depression aim of this study was to assess the effi cacy of a problem-solving intervention in preventing clinical depression in a sample of female caregivers. Method: A controlled randomized trial was conducted among 173 participants (mean age 53.9 years), 89 of whom were randomized to the intervention group and 84 (controls) to usual care. The intervention comprised fi ve weekly 90-minute group sessions. Results: At post-treatment, depression symptoms in the intervention group had remitted signifi cantly more than in the control group, with a large effect size (d = 1.54). The proportion of participants showing clinically signifi cant improvement was signifi cantly larger in the intervention group (80.9% vs. 11.9% among controls), and fewer intervention-group participants had progressed to clinical depression during the study period (4.5% vs. 13.1% among controls). The intervention group also exhibited a signifi cantly greater reduction in emotional distress and caregiver burden than the control group. Conclusions: These fi ndings attest to the short-term effi cacy of the intervention."
