Efficacy of learning through play plus intervention to reduce maternal depression in women with malnourished children: A randomized controlled trial from Pakistan

•Significant improvement in depression amongst women in the intervention (LTP Plus) group as compared to the treatment as usual (TAU) group, at 3 and 6 months from baseline.•Scores for social support and health related quality of life improved significantly amongst the LTP plus group as compared to the TAU group.•The number of days the malnourished children suffered from diarrhoea and chest infection were approximately 50% lower and three-fold lower respectively, in the intervention group as compared to TAU group. The risk factors and adverse outcomes related to maternal depression and child malnutrition are a leading cause of morbidity and mortality in low and middle-income countries (LMIC) including Pakistan. Above 25% of women suffer from maternal depression. Up to 50% children are under-nourished which contributes to 35% of all under-5 deaths in the country. To determine the efficacy of Learning through Play Plus Thinking Healthy Program (LTP Plus) intervention to reduce maternal depression in mothers with undernourished children. In this randomised controlled trial, all eligible mothers presenting to the paediatric departments were invited to participate in the study. Out of the total 256 mothers screened, 107 were included, 54 of those were randomly allocated to LTP Plus group and 53 to treatment as usual (TAU). Edinburgh Postnatal Depression Scale (EPDS) was used to screen for depression. Hamilton Depression Rating Scale (HDRS), Maternal Attachment Inventory (MAI), Social Support Scale (OSLO-3) and the Euro-QoL (EQ-5D) were used to measure the severity of depression, mother-child attachment, level of support and health related quality of life dimensions. Assessments were completed at baseline, end of intervention (3 months from baseline) and at 6 months from baseline. Mothers in the LTP Plus group significantly showed improvements in depression (p
