An item pool was formulated from the literature and in-depth interviews based on the health belief model. Content validation was conducted by experts and through cognitive interviews with women of childbearing age. Construct and concurrent validity and reliability were evaluated using factor analysis, Pearson’s correlation analysis, and Cronbach’s alpha.Results: The HBM-PBP consisted of 96 items, including perceived susceptibility (21 items, 5 subscales), severity (26 items, 5 subscales), benefits (27 items, 5 subscales), and barriers (22 items, 5 subscales). Convergent and discriminant validity were supported. The Cronbach’s alpha coefficient of the domains ranged from 0.87 to 0.94.Conclusion: The HBM-PBP is a valid and reliable measurement scale with good psychometric properties. It can be used to measure health beliefs in women, either as a whole or in individual domains. Health professionals can leverage the HBM-PBP to discern women’s health beliefs on premature birth, facilitating tailored interventions and educational efforts.Keywords: health belief model, premature birth, reproducibility of results, surveys and questionnaires, women
