目的:开发并验证36项月经实践需求量表(MPNS-36)的简短和快速形式。
方法:项目减少优先考虑内容有效性,并通过对孟加拉国女学生的认知访谈获得信息,规模项目在过去研究和利益相关者反馈中的表现。原来的MPNS-36被重新验证,以及在横断面调查中测试的短而快速的形式。接下来是进一步的维度测试,多个横断面调查的内部一致性和有效性。
方法:在对Khulna的313名月经女孩(平均年龄=13.51)的调查中,制定了简短形式(MPNS-SF)和快速形式(MPNS-R)措施,孟加拉国。他们在青少年月经体验和健康队列的基线调查中进一步测试,在Khulna,孟加拉国(891名月经来潮女孩,平均年龄=12.40);以及来自索罗蒂MPNS-36开发的数据集,乌干达(538名月经来潮的女孩,平均年龄=14.49)。
结果:18项简短表格反映了六个原始分量表,四个核心子量表在所有三个样本中都表现出良好的拟合(Khulna飞行员:近似均方根误差(RMSEA)=0.064,90%CI0.043至0.084,比较拟合指数(CFI)=0.94,塔克-刘易斯指数(TLI)=0.92。队列基线:RMSEA=0.050,90%CI0.039至0.062,CFI=0.96,TLI=0.95。乌干达:RMSEA=0.039,90%CI0.028至0.050,CFI=0.95,TLI=0.94)。9个项目的快速形式捕捉不同的需求。双因素结构是最合适的,但没有足够的拟合(Khulna飞行员:RMSEA=0.092,90%CI0.000至0.158,CFI=0.93,TLI=0.89)。在所有人群中,MPNS评分和其他构建体之间的假设关联在MPNS-36和MPNS-SF之间具有可比性。并复制,随着衰减,在MPNS-R中内部一致性仍然可以接受。
结论:MPNS-SF提供了一个可靠和有效的测量青春期女孩月经卫生体验的方法,同时减少了参与者的负担,支持实施和改善月经健康研究的测量。MPNS-R提供了一个结构有效性较差的简短度量,适合短期调查,并将月经健康纳入更广泛的研究课题。
OBJECTIVE: Develop and validate short and rapid forms of the 36-item Menstrual Practice Needs Scale (MPNS-36).
METHODS: Item reduction prioritised content validity and was informed by cognitive interviews with schoolgirls in Bangladesh, performance of scale items in past research and stakeholder feedback. The original MPNS-36 was revalidated, and short and rapid forms tested in a cross-sectional survey. This was followed by further tests of dimensionality, internal consistency and validity in multiple cross-sectional surveys.
METHODS: Short form (MPNS-SF) and rapid form (MPNS-R) measures were developed in a survey of 313 menstruating girls (mean age=13.51) in Khulna, Bangladesh. They were further tested in the baseline survey of the Adolescent Menstrual Experiences and Health Cohort, in Khulna, Bangladesh (891 menstruating girls, mean age=12.40); and the dataset from the MPNS-36 development in Soroti, Uganda (538 menstruating girls, mean age=14.49).
RESULTS: The 18-item short form reflects the six original subscales, with the four core subscales demonstrating good fit in all three samples (Khulna pilot: root mean square error of approximation (RMSEA)=0.064, 90% CI 0.043 to 0.084, Comparative Fit Index (CFI)=0.94, Tucker-Lewis Index (TLI)=0.92. Cohort baseline: RMSEA=0.050, 90% CI 0.039 to 0.062, CFI=0.96, TLI=0.95. Uganda: RMSEA=0.039, 90% CI 0.028 to 0.050, CFI=0.95, TLI=0.94). The 9-item rapid form captures diverse needs. A two-factor structure was the most appropriate but fell short of adequate fit (Khulna pilot: RMSEA=0.092, 90% CI 0.000 to 0.158, CFI=0.93, TLI=0.89). Hypothesised associations between the MPNS scores and other constructs were comparable between the MPNS-36 and MPNS-SF in all populations, and replicated, with attenuation, in the MPNS-R. Internal consistency remained acceptable.
CONCLUSIONS: The MPNS-SF offers a reliable and valid measure of adolescent girls\' menstrual hygiene experience while reducing participant burden, to support implementation and improve measurement in menstrual health research. The MPNS-R provides a brief measure with poorer structural validity, suited to short surveys and including menstrual health within broader research topics.
