Group problem solving therapy for perinatal depression in primary health care settings in rural Uganda: an intervention cohort study

Abstract

Background: Perinatal depression is of substantial public health importance in low and middle income countries. The study aimed to evaluate the impact of a mental health intervention delivered by non-specialist health workers on symptom severity and disability in women with perinatal depression in Uganda. Methods: Pregnant women in the second and third trimester were consecutively screened using the Luganda version of the 9-item Patient Health Questionnaire (PHQ-9). Women who scored ≥5 on the PHQ-9 and who were confirmed to have depression by a midwife were recruited into a treatment cohort and offered a psychological intervention in a stepped care fashion. Women were assessed with PHQ-9 and WHODAS-2.0 at baseline and again at 3 and 6 months after the intervention. Negative regression analysis was done to examine change in PHQ-9 and WHODAS-2.0 scores from baseline to end line. Data were analysed using STATA version 14. Results: A total of 2652 pregnant women (98.3%) consented to participate in the study and 153 (5.8%) were diagnosed as depressed. Over a quarter (28.8%) reported having experienced physical interpersonal violence (IPV) while (25.5%) reported sexual IPV in the past year. A third (34.7%) of women diagnosed with depression received 4 or more group PST sessions. There was a mean reduction in PHQ-9 score of 5.13 (95%CI − 6.79 to − 3.47, p < 0.001) and 7.13 (95%CI − 8.68 to − 5.59, p < 0.001) at midline and endline, respectively. WHODAS scores reduced significantly by − 11.78 points (CI 17.64 to − 5.92, p < 0.001) at midline and − 22.92 points (CI 17.64 to − 5.92, p < 0.001) at endline. Clinical response was noted among 69.1% (95%CI 60.4–76.6%) and 93.7% (95%CI 87.8–96.8%) of respondents at midline and endline, respectively. Conclusion: An evidence based psychological intervention implemented in primary antenatal care by trained and supervised midwives in a real-world setting may lead to improved outcomes for women with perinatal depression. Future randomised studies are needed to confirm the efficacy of this intervention and possibility for scale up.
