Verification of the Validity of a Measurement Scale for Menstrual Abnormalities in Young Women and Consideration of Related Factors

Abstract

[Purpose] To verify a measurement scale for menstrual abnormalities in young women and identify related factors.
[Method] The concept of menstrual abnormalities was analyzed targeting 31 papers from Japan and abroad¹⁾. A preliminary survey was carried out on 300 respondents. This survey was carried out on 600 persons and testing was carried out a week later. Valid responses were obtained from 300 persons, and a 4-factor, 25-item scale was abstracted. A survey on related factors was carried out on 400 persons, and correlation with eating habits, sleeping habits and physical discomfort were considered.
[Ethical considerations] This study was carried out after obtaining approval from the Ethical Review Committee of Tokyo Women‘s Medical University (Approval No: 2021-0188).
[Results] 400 women with menstrual abnormalities were targeted for analysis. A 4-factor, 25-item scale according to the analysis results of the confirmation factors could be confirmed. According to the analysis of covariance structures, a strong correlation was observed in goodness-of-fit model for 4 factors and eating habits, sleeping habits, and physical discomfort, at GFI=0.997, AGFI=0.978, CFI=0.999 and RMSEA=0.017.
[Conclusion] Construct validity, criteria and internal consistency of this scale could be confirmed, and the 4-factor, 25-item scale could be validated.
A strong correlation between the 4 factors and eating habits, sleeping habits and physical discomfort was observed.
