*Complete cases refer to the subset of participants who were eligible to answer all questions. That is, participants who disposed of menstrual materials and attended and changed menstrual materials at school at least once during their last menstrual period.
†Excluding school refers to the subset of participants who answered all questions about their experience except those related to changing their menstrual materials at school, as they did not change materials at school.
‡Reuse insecurity and reuse needs apply only to a subset of the sample and were not included in CFA. CFA included the seven other items.
CFI, Comparative Fit Index; MPNS, Menstrual Practice Needs Scale; RMSEA, root mean square error of approximation; TLI, Tucker-Lewis Index.
