Reliability and validity study of the "5Cs" hesitancy scale for maternal influenza vaccination among pregnant and postpartum women.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMaternal influenza vaccine hesitancy plays a vital role in the low rates of vaccination. However, instruments to appropriately assess perinatal influenza vaccine hesitancy are unavailable. This study aimed to develop the Maternal Influenza Vaccine Hesitancy Scale based on the 5C vaccination hesitancy scale, containing the subscales of confidence, complacency, constraints, calculative, and collective responsibility, and to provide a preliminary overview of the current hesitancy on maternal influenza vaccination in China.
methodsA cross-sectional survey, from January to March 2024, was carried out among 2035 pregnant and postpartum women from nine provincial-level administrative divisions representing eastern, central, western, and northeastern areas of China. Reliability was evaluated by internal consistency reliability and split-half reliability, and a Cronbach's alpha coefficient > 0.7 was considered acceptable. Construct validity was assessed using confirmatory factor analysis (CFA), with good model fit defined as root mean square error of approximation (RMSEA) < 0.100, normed fit index (NFI) > 0.9, comparative fit index (CFI) > 0.9, and Tucker-Lewis index (TLI) > 0.9.
resultsConfirmatory factor analysis results supported the five-factor structure of the scale (RMESA = 0.098, CFI = 0.921, TLI = 0.903, NFI = 0.918). The Cronbach's alpha coefficients for the scale as well as the subscales ranged from 0.802 to 0.958. Among five subscales, collective responsibility (2.73 ± 0.63) scored highest, while complacency (2.16 ± 0.69) and constraints (2.17 ± 0.69) were the lowest.
conclusionsThe Maternal Influenza Vaccine Hesitancy Scale developed in this study is a reliable and valid instrument to measure the influenza vaccine hesitancy of pregnant and postpartum women. It is recommended that interventions including health education and improving the access to the vaccination service be carried out to reduce the maternal influenza vaccination hesitancy.
