Strengths and limitations of this study► This study reports the development and validation of the Menstrual Practice Needs Scale (MPNS-36) and the conceptual justification for the measure. ► Measure development drew on systematic reviews and findings from studies of measurement challenges in menstrual health research across a range of contexts. ► The MPNS-36 sought to measure the degree to which the practices and environments used in managing menstrual bleeding meet respondents' needs. ► There were no existing validated measures of menstrual experience against which to demonstrate the convergent and divergent validity of the scale. ► The scale was tested among schoolgirls in Uganda, a single population and language, and requires further research on cross-cultural validity and use in other populations. AbStrACtObjective This study describes the development and validation of the Menstrual Practice Needs Scale (MPNS-36), which measures the extent to which respondents' menstrual practices and environments meet their needs.Methods A 54-item pool was developed following systematic review of qualitative and quantitative studies and expert feedback. Item reduction and scale validation were undertaken using a cross-sectional survey of 538 menstruating schoolgirls in Soroti, Uganda. Test-retest reliability was assessed in a subsample of 52 girls 2 weeks after the first administration. Construct validity was tested through relationships with hypothesised correlates: confidence to manage menses, self-reported school absenteeism and mental health symptoms.results The MPNS-36 comprises 28 items applicable to all respondents and 8 items capturing washing and drying experiences for those reusing menstrual materials. A four-factor solution for the core 28 items was the best fit for the data (root mean square error of approximation (RMSEA)=0.028-0.029; comparative fit index (CFI)=0.961-0.964; Tucker-Lewis index (TLI)=0.953-0.955), supplemented by two factors for reuse (RMSEA=0.021-0.030; CFI=0.987-0.994; TLI=0.981-0.991). Subscale and total scores were calculated as mean scores to support accessibility for practitioners. The subscales were 'material and home environment needs' (11 items, α ordinal =0.84), 'transport and school environment needs' (5 items, α ordinal =0.73), 'material reliability concerns' (3 items, α ordinal =0.55), 'change and disposal insecurity' (9 items, α ordinal =0.80), 'reuse needs' (5 items, α ordinal =0.76) and 'reuse insecurity' (3 items, α ordinal =0.56). Relationships between subscales and hypothesised correlates supported validity. Home-based and school-based items were more strongly associated with confidence to manage menstruation at home and school, respectively. Higher total scores indicated more positive experiences and were associated with greater odds of not missing school during the last menstrual period (OR=2.62, 95% CI 1.52 to 4.50). Test-retest reliability was moderate (total score: intraclass correlation coefficient, ICC (2,1) =0.69).Conclusions The MPNS-36 demonstrated acceptable reliabili...
High-quality evidence is needed to inform policies and programmes aiming to improve menstrual health. Quantitative studies must address the many evidence gaps in this field, and practitioners have increased monitoring and evaluation efforts to track their progress. A significant barrier to improving the rigor of this work is the lack of comprehensive and comparable measures to capture core concepts. The Menstrual Practices Questionnaire (MPQ) is a new tool to support comprehensive and standardised assessment of the activities undertaken in order to collect, contain, and remove menstrual blood from the body in selfreport surveys. The questionnaire is freely available online for download and can be adapted for use across contexts and age groups. In this article, we describe the purpose of the MPQ as a best-practice tool to align the description of menstrual practices and provide a foundation for further question refinement. We outline the development of the tool using systematic review of qualitative studies of menstrual experiences, audit of measures used in the study of menstrual health and hygiene, survey of experts, insights from past research, and examples from piloted questions in a survey of adolescent girls in Soroti, Uganda. We describe the identification of menstrual practices as a priority for measurement, coverage of practices included in the MPQ, and justify the inclusion of location-specific questions. For each section of the questionnaire, we outline key reasons for the inclusion of practice items alongside elaboration for users to help inform item selection. Finally, we outline priorities for future research to refine the assessment and reporting of menstrual practices, including the identification of minimum reporting requirements for population characteristics to facilitate comparison across studies, testing the extent to which experiences during the most recent menstrual period reflect those over longer time periods, and further exploration of biases in self-report.
Objectives. This study describes the development and validation the Menstrual Practice Needs Scale (MPNS-36) which measures the extent to which females’ menstrual practices and environments meet their needs. Methods. A 54-item pool was developed following systematic-review of qualitative and quantitative studies and expert feedback. Item reduction and scale validation were undertaken using a cross-sectional survey of 538 menstruating schoolgirls in Soroti, Uganda. Test-retest reliability was assessed in a sub-sample of 52 girls two weeks after the first administration. Construct validity was tested through relationships with hypothesised correlates: confidence to manage menses, self-reported school absenteeism, and mental health symptoms. Results. The final MPNS-36 comprises 28 items applicable to all respondents, and 8 items capturing washing and drying experiences for those reusing menstrual materials. A four-factor solution for the core 28 items was the best fit for the data (RMSEA=0.028-0.029; CFI=0.961-0.964; TFI=0.957-0.959), supplemented by two factors for reuse (RMSEA=0.021-0.030; CFI=0.987-0.994; TFI=0.981-0.991). Subscale and total scores were calculated as mean scores to support accessibility for practitioners. Subscales were ‘material and home environment needs’ (11 items, α-ordinal=0.84), ‘transport and school environment needs’ (5-items, α-ordinal=0.73), ‘material reliability concerns’ (3-items, α-ordinal=0.55), ‘change and disposal insecurity’ (9-items, α-ordinal=0.80), ‘reuse needs’ (5-items, α-ordinal=0.76), and ‘reuse insecurity’ (3-items, α-ordinal=0.56). Relationships between subscales and hypothesised correlates supported validity. Home- and school-based items were more strongly associated with confidence to manage menstruation at home and school, respectively. Higher scores predicted not missing school during the last menstrual period (total score: OR=2.62, 95%CI=1.52-4.50). Test-retest reliability was moderate (total score: ICC(2,1)=0.69).Conclusions. The MPNS-36 demonstrated acceptable reliability and validity. It is the first measure to capture women and girls perceived menstrual hygiene and may be used across a range of study designs to assess menstrual needs. Future research should explore the suitability and sensitivity of the measure across contexts.
