Cross Adaptation Quality Of Life Questionnaire For Periodontitis Patients (Modified Indonesian Version) In Menopausal Women

Background:Changes in steroidal sex hormones in peri- and post-menopausal women affect their bodies, including their periodontal tissues. Disorders of periodontal tissues can impact the patient's quality of life, so a valid instrument in measuring quality of life is needed in order to know how much periodontitis affects the quality of life of sufferers in peri and postmenopausal women.Objective:This study aimed to examine the validity and reliability of the quality of life questionnaire for patients with periodontitis (modified Indonesian version). Methods: Cross-cultural adaptation was tested in peri- and post-menopausal women aged 45-59 years. The reliability and validity of the questionnaire was examined among 268 women, who lived in Jakarta and were undergoing a periodontal examination to determine periodontitis severity.Results:Cronbach's a coefficients for internal consistency were: 0.929 (questions related to gums) and 0.942 (questions related to teeth); The test-retest reliability was good as determined based on a test-repeat test involving 27 women; the interclass coefficient was 0.880 (questions related to gums) and 0.878 (questions related to teeth). The construct validity of the questionnaire (questions related to gums and teeth) showed that the questionnaire was significantly associated with oral health and food taste (P<0.001). The discriminant validity of the questionnaire, the influence of the gums on speaking difficulties (P=0.011) and family life (P=0.025) and the influence of the teeth on family life (P=0.020) and mood (P=0.019) could enable differentiation of periodontal severity in peri- and post-menopausal women.Conclusion:This study confirmed the reliability and validity of the quality of life questionnaire for patients with periodontitis (modified Indonesian version) in peri- and post-menopausal women, therefore this questionnaire can be used to measure the quality of life of periodontitis patients in peri and postmenopause in Indonesia.
