Postpartum mothers are at risk of experiencing stress and anxiety, which may develop into postpartum depression. Postpartum depression, which negatively affects the well-being of both mother and baby, is influenced by various factors, including breastfeeding self-efficacy. This study aimed to identify the relationship between breastfeeding self-efficacy and the tendency toward postpartum depression. A cross-sectional design was employed, involving 112 respondents in Depok City. Data were collected using the Breastfeeding Self-Efficacy – Short Form and the Edinburgh Postpartum Depression Scale questionnaires. The results indicated that 41% of respondents had low breastfeeding self-efficacy, and 45.5% were prone to postpartum depression. The Chi-Square test showed a significant association between breastfeeding self-efficacy and postpartum depression (p = 0.007, p < 0.05), with an odds ratio of 2.908. These findings suggest that mothers with low breastfeeding self-efficacy are 2.9 times more likely to develop a tendency toward postpartum depression. This study recommends interventions to enhance breastfeeding self-efficacy to reduce the risk of postpartum depression.
