Objective:
Hot flashes are one of the major symptoms of climacteric syndrome. Despite the high prevalence of these symptoms, few questionnaires assessing the impact of hot flashes on quality of life have been validated. The aim of this study was to validate a French version of the Hot Flash Related Daily Interference Scale (HFRDIS) in a sample of French women.
Methods:
In this prospective study, data were obtained from two groups of women aged between 40 and 60 years from both women without breast cancer and women under hormone therapy for breast cancer between March 2021 and February 2022. Translation was made by an official English-French translator using the forward-backward method.
Results:
One hundred and sixty-seven women completed the HFRDIS questionnaire. The scree plots confirmed unidimensional structure. Cronbach's α coefficient was 0.92 [0.90-0.94] similar to the original version. The intra-class correlation coefficients of each item ranged between 0.58 and 0.71 Concordance of the scores of each item with those obtained during the validation of the original version of the HFRDIS was confirmed.
Conclusion:
The validation results show that the French version of the HFRDIS questionnaire is a valid tool to evaluate the impact of hot flashes on the daily life activities of patients.
