Abstract:
Objective:To evaluate the reliability and validity of Short-form health survey-36 (SF-36) during the first trimester of pregnancy.Methods:From January 2020 to January 2021, pregnant women aged 18―40 during the first trimester visit were admitted to the Obstetric Department of Beijing Obstetrics and Gynecology Hospital, Capital Medical University. Split-half reliability and Cronbach′s α coefficients were used to evaluate the reliability. The convergent and discriminative validity were evaluated by using AMOS 24.0 and the criterion-rated validity was evaluated with correlation analysis and non-parameter test. Exploratory factor analysis and confirmatory factor analysis based on structural equation modeling were used in the evaluation of contract validity.Results:SF-36 scale had good reliability (split-half reliability: R=0.901, Cronbach′s α coefficients=0.878), convergent validity, discriminate validity and the criterion-rated validity ( r=0.907). Second-order confirmatory factor analysis model was not well-fitted ( RMSEA=0.070, χ 2/dF=3.566, GFI=0.813, CFI=0.814, TLI=0.792, NFI=0.761), indicating that the construct validity was poor. Conclusions:The reliability, consolidation validity, discrimination validity and criterion-related validity of Sf-36 scale are good, while the construct validity is poor. Improvement is needed when the scale is used for pregnant women.
