This study evaluated the psychometric performance of the American version of the 30-item Endometriosis Health Profile (EHP-30) in a multi-centre Phase III randomized trial that enrolled 225 patients across 43 U.S. clinic sites, using baseline self-completed questionnaires from participants receiving depot medroxyprogesterone acetate or leuprolide acetate. Researchers assessed response rate, data completeness and quality, reliability, and whether scaling assumptions held, and found very high data completeness (97.33% completing all items, with no more than two missing responses per item) with no floor or ceiling effects across dimensions. Internal consistency reliability was high for all dimensions (Cronbach’s alpha 0.84–0.91), supporting the instrument’s previously established scaling and psychometric properties in an American context; the main limitation noted is that analyses used baseline data and combined treatment groups. This paper is centrally about endometriosis — specifically, it validates the EHP-30 questionnaire for use in the USA.
