Background:
Dysmenorrhea is a gynecological condition that causes painful menstrual cramps in the uterus, most commonly seen in women of reproductive age. The aim was to perform the reliability and validity of the Turkish Working Ability, Location, Intensity, Days of Pain, Dysmenorrhea (WaLIDD) score for evaluating individuals with dysmenorrhea. The evaluation of the reliability and validity of the Turkish version of the WaLIDD tool in the Turkish population is essential to ensure its accuracy, consistency, and cultural relevance in assessing the impact of dysmenorrhea.
Methods:
Cross-sectional, psychometric questionnaire research. 113 individuals with dysmenorrhea were included in the study. The reliability of the WaLIDD was evaluated using internal consistency and test-retest analyses, while its validity (both convergent and divergent) was assessed through correlation analysis. For correlation analysis WaLIDD, Premenstrual Syndrome Impact Questionnaire (PMS-IQ), Pain Disability Index (PDI), and Big Five Inventory-10 (BFI-10) were used.
Results:
The reliability analysis indicated that the questionnaire demonstrated an internal consistency value of 0.875 and an intraclass correlation coefficient (ICC) value of 0.778. Pearson correlation analysis indicated that the WaLIDD had a very well correlation with the PMS-IQ (0.726) and well correlation with the PDI (0.413). WaLIDD had a negligible correlation with the BFI-10 (0.088). There were no floor or ceiling effects observed in the Turkish version of the WaLIDD.
Conclusions:
WaLIDD was found to be a well-structured, valid, and reliable instrument that can be used to evaluate women with dysmenorrhea. The Turkish version of WaLIDD can be used in Turkish women in clinical practices and research.
Trial Registration:
This study was registered in ClinicalTrials.gov (NCT05829512).
