Abstract

Objective Qualitative studies have described girls’ varying levels of confidence in managing their menstruation, with greater confidence hypothesized to positively impact health, education, and social participation outcomes. Yet, measurement of this and other psychosocial components of adolescent girls’ menstrual experiences has been weak in global health research, in part due to a dearth of appropriate psychometric tools. We describe the development and validation of the Self-Efficacy in Addressing Menstrual Needs Scale (SAMNS-26). Methods We conducted nine focus group discussions with girls in schools in rural and urban Bangladesh to identify tasks involved in menstrual self-care. This informed our creation of an initial pool of 50 items, which were reviewed by menstrual health experts and refined through 21 cognitive interviews with schoolgirls. Using a self-administered survey, we administered 34 refined items plus additional validation measures to a random sample of 381 post-menarcheal girls (ages 9–17) and retested a subsample of 42 girls two weeks later. We examined the measure’s dimensionality using exploratory factor analysis and assessed internal consistency, temporal stability, and construct validity. Results Exploratory factor analysis suggested a 26-item scale comprising three correlated sub-scales: the 17-item Menstrual Hygiene Preparation and Maintenance (α = 0.86), the 5-item Menstrual Pain Management (α = 0.87), and the 4-item Executing Stigmatized Tasks (α = 0.77). Sub-scales exhibited good temporal stability. SAMNS-26 scores correlated negatively with measures of anxiety, and girls who preferred to stay at home during their periods had lower SAMNS-26 scores than those who did not. Conclusion The SAMNS-26 provides a reliable measure of a schoolgirl’s confidence in her capabilities to address her menstrual needs. There is initial evidence to support the measure’s construct validity in the Bangladesh context as indicated by its relationships with other factors in its theorized nomological network. The tool enables incorporation of self-efficacy into multivariate models for exploring the relationships among antecedents to menstrual experiences and hypothesized impacts on health, wellbeing, and education attainment. Further testing of the tool is recommended to strengthen evidence of its validity in additional contexts.
