Brief Summary:

Endometriosis and adenomyosis can impact on the quality of life including the physical, psychological and social aspects. It is important to include quality of life measurements in evaluating the disease severity and response to any given treatment. The 30-item Endometriosis Health Profile (EHP-30), derived from in-depth interviews of patients with endometriosis, is currently the most reliable questionnaire for health-related quality of life measurement in women with endometriosis. It includes specific questions addressing the problems faced by patients with endometriosis.

Unfortunately, this widely accepted tool does not have a traditional Chinese version for the measurement of health-related quality of life of endometriosis in Hong Kong. Furthermore, adenomyosis and endometriosis share similar histological and clinical symptomatology, but application of EHP-30 to adenomyosis has never been studied.

The aims of the present study are to translate the EHP-30 English version into traditional Chinese version and to evaluate its psychometric properties in endometriosis and adenomyosis.

The hypothesis of this study is that EHP-30 (Hong Kong) traditional Chinese questionnaire has high internal consistency, construct validity, reproducibility as the original English version and can be applicable to Hong Kong Chinese women with endometriosis and adenomyosis.
