Abstract
OBJECTIVES: To validate the Turkish-translated versions of the Endometriosis Health Profile 5 (EHP-5) for use in patients with laparoscopically proven endometriosis. STUDY DESIGN: This case control study was conducted in a tertiary referral teaching institution between April and June 2014. Fifty-eight patients with surgically proven endometriosis were enrolled. The EHP-5 questionnaire was evaluated for patients with laparoscopically diagnosed endometriosis. Test-retest reliability, descriptive statistics, reliability analysis (internal consistency and item-total correlation), data completeness, and known-group comparison were all assessed in the validation of the EHP-5 form as translated into the Turkish language. RESULTS: Two weeks test-retest reliability showed statistically significant correlation; Spearman's rho was 0.885 (p<0.001) for the EHP-5 core questionnaire and 0.896 (p<0.001) for the EHP-5 modular questionnaire. Cronbach's alpha values for the translated form of the EHP-5 core and modular questionnaires were 0.829 and 0.804, respectively, with a high level of internal consistency. In known group comparison, there were statistically significant differences in all subgroups except in the infertility group on the core questionnaire. Pain scales on the core questionnaire and infertility scales on the modular questionnaire showed the highest mean scores (1.14±1.16 and 1.78±1.77). CONCLUSION: Like the original English questionnaire, the Turkish-translated version of the EHP-5 is a reliable and valid instrument for assessing symptom severity and the impact of endometriosis on health-related quality of life in Turkish-speaking women.
