RT Journal Article SR Electronic T1 Improving Mental Health of Adolescent Girls in Low- and Middle-Income Countries JF Journal of Human Resources FD University of Wisconsin Press SP S317 OP S364 DO 10.3368/jhr.1222-12707R2 VO 59 IS S A1 Shah, Manisha A1 Baird, Sarah A1 Seager, Jennifer A1 Avuwadah, Benjamin A1 Hamory, Joan A1 Sabarwal, Shwetlena A1 Vyas, Amita YR 2024 UL http://jhr.uwpress.org/content/59/S/S317.abstract AB This study provides causal evidence on the impact of life skills programming on the mental health of adolescent girls aged 10–19 in three distinct low- and middle-income countries: Tanzania, Bangladesh, and Ethiopia. Life skills interventions significantly improved a component of mental health in all three contexts, with reductions in depression in Tanzania and improvements in socio-emotional development in Bangladesh and Ethiopia. However, findings suggest substantial heterogeneity in impact. Programs that target both adolescent boys and girls appear more effective than those that target girls alone, and existing supportive environments are a necessary condition for programs to improve mental health.
