Endometriosis Health Profile – 30 (EHP-30)
This is a self-report psychometric tool specifically for Endometriosis which is designed from the patient’s perspective and aims to assess HRQoL in Endometriosis (24). It consists of 30 items with 5 subscales (Pain, Control and powerlessness, Emotional wellbeing, Social support and Self-image (15). It also has a modular questionnaire with 5 items on sexual intercourse. The items were in the form of questions, with a five-point Likert-type scale and the answers ranged from 0 = never to 4 = always. It is scored from a range of 0-5 for the subscales and 0 (best health status) to 100 (worst health status) for the total score, with a higher score indicating a lower Endometriosis-related quality of life (25). For the modular questionnaire there is also the option ’Not applicable’. The EHP-30 is considered a valuable psychometric tool for the effective evaluation of treatment in Endometriosis (26). The Greek translation of the EHP-30 by Psychogiou et al.1 is considered a reliable and valid measure with the Cronbach’s alpha ranging from 0.93–0.96. This tool is protected and so licence to use was obtained by the researchers.
