Introduction and hypothesis We aimed to translate the Day-to-Day Impact of Vaginal Aging (DIVA) Questionnaire into Turkish, adapt it culturally, and investigate its reliability and validity. Another aim of the study was to examine the relationship between the impacts of vaginal symptoms and pelvic floor symptoms on quality of life (QoL). We hypothesized primarily that the the Turkish DIVA had good internal consistency, test-retest reliability and construct and criterion validity. Our secondary hypothesis was that the effects of vaginal symptoms and pelvic floor symptoms on QoL would be positively related. Methods A total of 218 postmenopausal women were included. In the reliability analyses, Cronbach alpha coefficients, item-total correlation coefficients and intraclass correlation coefficients (ICCs) were used. Construct validity was investigated with explanatory and confirmatory factor analyses. Criterion validity and the relationship between the effects of vaginal symptoms and pelvic floor symptoms were examined by Pearson correlation analysis. Results While the Cronbach's alpha coefficients ranged between 0.87 and 0.96, the item-total score correlation coefficients were 0.60-0.91. ICCs ranged from 0.90 to 0.99. It was found with confirmatory factor analysis that the model fit the data. Moderate-strong correlations (r = 0.47-0.73) were observed between DIVA scores and the scores of other scales (p < 0.001). Conclusions The Turkish DIVA is a reliable and valid tool that comprehensively evaluates the impact of vaginal symptoms on women's QoL. The positive relationship between the impacts of vaginal and pelvic floor symptoms on functionality and well-being of women suggests a holistic view in pelvic health care.
