Supplementary file 1_Breastfeeding self-efficacy as a mediator between sense of coherence and perception of milk supply among postpartum women: a cross-sectional study.docx

Adding BSES-SF increased explained variance in HHLS total score from 10.4 to 36.1%. The parsimonious indirect estimate was 0.187 (bootstrap 95% CI 0.097 to 0.299), and the expanded estimate was 0.044 (−0.002 to 0.108). Indirect associations were evident for HHLS Maternal confidence/commitment (0.086, 0.036 to 0.152) and satisfaction (0.102, 0.057 to 0.155), but not infant satiety (−0.001, −0.021 to 0.019).

After excluding 48 women currently formula feeding, the corresponding estimates remained positive in both the parsimonious (0.199, 0.102 to 0.323) and expanded (0.061, 0.004 to 0.147) models.</p>Conclusion<p>Breastfeeding self-efficacy was related to mothers’ broader appraisal of lactation, particularly confidence and satisfaction, and the principal pattern remained among women who were currently breastfeeding. The findings did not extend to perceived infant satiety and do not establish temporal mediation.

BSES-SF may complement, but should not replace, clinical assessment of lactation and infant intake.</p>
