Abstract
Aim. Midwives are prone to suboptimal health status (SHS), while there is a lack of unified measurement standard of SHS for them to early detect and prevent SHS. This study aimed to evaluate validity and reliability of Subhealth Measurement Scale V1.0 (SHMS V1.0) in midwives. Design and Methods. The cross-sectional study had 842 midwives from 46 midwifery institutions in southeastern China completing the SHMS V1.0 with 39 items. Internal consistency, test-retest reliability, and concurrent validity of SHMS V1.0 were assessed. Project analysis and confirmatory factor analysis (CFA) were performed to assess construct validity. Results. SHMS V1.0 had acceptable reliability with Cronbach’s alpha and a test-retest reliability coefficient of 0.908 and 0.804, respectively. The correlation coefficients between each item and corresponding dimension and those between dimension and corresponding subscale were all greater than 0.4. The CFA supported the structure of SHMS V1.0 with strong factor loadings and excellent fit indexes in the first-order and modified second-order factor model, illustrating that SHMS V1.0 had good construct validity among midwives. The concurrent validity for SHMS V1.0 showed large correlation with FS-14, but the social subscale showed medium correlations with fatigue, inferring that SHMS V1.0 can more comprehensively reflect SHS of midwives than FS-14, especially for social health symptoms. Practice Implications. SHMS V1.0 with excellent psychometric properties can accurately and reliably evaluate the SHS of midwives. These findings of our study provide an important measurement tool and inspiration for midwives to early detect and prevent SHS.
