Vural PI, Varısoglu Y. Menstrual Practice Needs Scale (MPNS): Reliability and Validity of the Turkish Version. Cyprus
J Med Sci. 2021; 6(4): 295-302.
The determination of CVI 0.89 for this scale demonstrates that content validity is adequate. When the Kaiser–Meyer–Olkin (KMO) value of this scale was tested, it was determined to be 0.819, and this result indicates that it is very good for factor analysis. Besides, the result of Bartlett’s Test of Sphericity was v2 ¼ 4,894.399, P < .001 for MPNS. Item-total correlation factor loadings of the scale (path coefficients) varied from 0.24 to 0.94.
In this study, Cronbach’s value was determined as 0.76, which was acceptable for internal validity. The corrected item-total correlation of this scale was analyzed, which ranged from 0.14 to 0.68 and decided to be an acceptable level. According to this result, the 28th item (“When at school, I worried that someone would harm me while I was changing my menstrual materials.”) was removed because the total correlation value of this item was under 0.30. After the 28th item was removed, item-total correlation values of the items in the scale varied from 0.313 to 0.683, and Cronbach’s value increased to 0.78. the correlation value between the first and second application scores of the MPNS was determined to be r ¼ 0.661, with a significant difference with a P < .001 level.
