RESUMO
Objective To develop a suitable instrument for measuring health beliefs related to reproductive tract infections (RTIs) and testing its reliability and validity. Methods Within the framework of the Health Belief Model, 500 questionnaires of health beliefs related to RTIs were collected, its reliability and validity was analyzed. Results The instrument contained two subscales, all content validity index(CVI)were 1.0. RTIs-related health belief subscale extracted four factors, the cumulative variance was 75.91%;RTIs-related self-efficacy subscale extracted four factors,the cumulative variance was 68.19%. Scale statistics consisted with the structure and design structure. The dimensions Cronbach's α coefficient, test-retest reliability, split half reliability were greater than 0.70. Conclusions This scale has good reliability and validity and can be used for measuring health beliefs related to reproductive tract infections in women of childbearing age.
