The Open Public Health Journal 4 Sept 2023 RESEARCH ARTICLE DOI: 10.2174/18749445-v16-230818-2023-33



Lumbopelvic pain (LPP) is a surging problem among women worldwide. The genesis of LPP among women is complex as it constitutes a wide array of gynecological, hormonal, gastrointestinal, and obstetrical factors.


The objective was to develop and evaluate the content validity of a questionnaire designed to assess general LPP risk factors relevant to women.


The questionnaire was drafted by comprehensively drawing items from the literature. The drafted questionnaire was conceptualized using the modified Delphi method and sent to nine experts for professional opinions. Based on the expert evaluation, the draft questionnaire was modified/revised and again sent for expert responses.


Overall, three rounds of Delphi were administered to reach a consensus between experts finally. The content validity ratio (CVR) and content validity index (CVI) of the questionnaire was calculated. The newly developed questionnaire constituted 19 items identifying LPP risks in women. The CVI of the overall questionnaire (S-CVI) was 0.99. The questionnaire also reached a universal agreement (S-CVI/UA) of 0.89. In terms of reliability, the internal consistency of the questionnaire was good (Cronbach's alpha of 0.8), with excellent test-retest reliability (intra-class correlation coefficient=0.99). The developed questionnaire has 3 domains: ergonomics, general health & well-being, and gynecology & obstetrics.


Using the findings of this Delphi study, we contend that the 19 items enlisted in the ‘LPP risk factor questionnaire’ depicts a multiplicity of LPP risk factors in women. This questionnaire would be beneficial for clinicians during the prevention and assessment phase of lumbopelvic pain.
