Abstract
Objective: The objective of this study was to develop the
Menstrual Migraine Symptoms Scale (MMSS). Methods: The study
utilized a robust methodological design with a sample size of 582
participants. The data underwent a comprehensive analysis employing
various statistical techniques, including item analysis, Exploratory
Factor Analysis (EFA), Confirmatory Factor Analysis (CFA), Cronbach’s
alpha internal consistency coefficient, and the Intraclass Correlation
Coefficient (ICC) for test-retest reliability. To collect the study
data, Google Forms was employed for both the Socio-Demographic
Characteristics Form and the MMSS. Results: The two
sub-dimensions of the scale, consisting of 19 items, demonstrated
excellent internal consistency, with Cronbach’s alpha coefficients
ranging from 0.932 to 0.970. Furthermore, the total scale exhibited a
high level of internal consistency, with a Cronbach’s alpha coefficient
of 0.976. The item correlation values within the scale ranged from 0.741
to 0.921, indicating strong relationships between the items. Following
the identification of the factor structure through EFA, the construct
validity of the scale was further assessed using CFA with an additional
dataset. The results of the CFA demonstrated that the scale performed
exceptionally well across all evaluation metrics, affirming its
reliability and validity as a measurement tool with a robust two-factor
structure. Conclusion: The study findings conclusively
demonstrated the validity and reliability of the MMSS as a robust
measurement tool specifically designed for assessing female individuals.
With its proven accuracy and consistency, the scale can be confidently
employed to reliably evaluate and monitor menstrual migraine symptoms in
women.
