Abstract:
Objective:To develop a self-efficacy scale of milk donation and test its reliability and validity, in order to provide a scientific evaluation tool for the corresponding study.Methods:According to Bandura′s self-efficacy theory and consensus-based standards for the selection of health measurement instruments, the scale was developed by means of literature search, article pool establishment and expert letter consultation. A pre-survey was conducted on 30 newborn bereaved women, a formal investigation was conducted on 231 newborn bereaved women, and 115 newborn bereaved women were selected for exploratory factor analysis. Confirmatory factor analysis was performed on 116 parturients with neonatal loss to determine the reliability and validity of the scale.Results:The final scale includes 3 dimensions and 13 items. Three common factors were extracted by exploratory factor analysis, and the cumulative variance contribution rate was 77.962%. A scale with three dimensions, included breast milk donation resilience, breast milk donation cognition and breast milk donation motivation, and 13 items was determined. Confirmatory factor analysis showed that the model fit of the scale was good ( χ2/ df = 1.390, RMSEA = 0.063, RMR = 0.046, NFI = 0.924, NNFI = 0.971, GFI = 0.924, CFI = 0.977). The content validity index was 0.835. Cronbach′s α coefficient of the total volume table was 0.919, and the coefficients of each dimension were 0.892, 0.905 and 0.844, respectively. The broken half reliability of the scale was 0.893, and the broken half reliability of each dimension was 0.857, 0.881 and 0.711, respectively. The retest reliability of the scale was 0.814, and the retest reliability of each dimension was 0.803, 0.825 and 0.767, respectively. Conclusions:The scale has good reliability and validity, and can be used to evaluate the self-efficacy of milk donation in lost newborns.
