Validity and Reliability Testing of the Indonesian Version of the Exercise and Menstruation Questionnaire (EMQ-I) Assessing the Phenomenon of Menstruation in Sports

Menstruation is a natural biological process that occurs in women and is controlled by hormonal fluctuations. This study can support the achievements of female athletes, especially in Indonesia, where communication and perceptions related to menstruation have not been included in the criteria for creating training programs. This study aimed to examine the validity and reliability of the Indonesian version of the Exercise and Menstruation Questionnaire (EMQ-I) measuring the phenomenon of menstruation in sport. The population for this study was female athletes in Malang, Indonesia, aged 18-35 years, who participated in various sports with a total of 57 athletes. This study uses a methodological approach that combines qualitative and quantitative components. The qualitative stage involves translators and experts in the field of menstruation and sports to validate the content. The quantitative stage tests the validity and reliability using statistical analysis with results ranging from 0.628 to 0.909 and reliability ranging from 0.856 to 0.927. The results of the data analysis showed that 88.5% of the question items were valid to be announced to respondents. The total items to be announced were 33 items and had been tested for validity and reliability by experts and in-depth data analysis. This research is expected to be a literature material and input for coaches in Indonesia to create training programs that are suitable for women and improve sports achievements in Indonesia.
