Development of the National Norms of Negligence on children aged 0 to 35 months in rural areas of China

OBJECTIVE: To develop the National Norms of Negligence (NNN) for rural children aged 0 to 35 months. METHODS: According to multi-stage stratified cluster sampling principle, 10 provinces or municipalities (Jilin, Shanxi, Shanxi, Beijing, Anhui, Jiangsu, Hunan, Hubei, Yunnan, Chongqing) in China were selected. A national research group was formed collaboratively. A questionnaire was designed by ourselves. According to several statistical analysis methods, such as item, factor and reliability analysis etc. we determined the norm. The evaluation criteria of the scale were determined by percentile method. Finally, the reliability and validity of the norm were evaluated. RESULTS: In total, 2310 children were surveyed, in which the effective sample were 2227, with an effective rate as 96.4%. The scale consisted of 6 neglected dimensions and 65 items in total. The total Cronbach's a coefficient of the scale was 0.903, with the split-half reliability coefficient as 0.829, the parallel reliability as 0.720 and the re-test reliability as 0.678, respectively. The total neglect cut-off score of this scale was 139. CONCLUSION: The scale seemed to have perfect stability and reliability and all the statistical indicators met the psychometric demands.
