Objective: To construct and determine the weight of Index System for Assessing Parent s Ability on Child Injury Prevention, and to provide the basis for childhood injury intervention in family. Methods: Twenty four experts majored in related fields were invited to participate in Delphi consultation. The final index system was constructed according to the consulting results and the weight of primary and secondary indicators were calculated. Results: The final index system consisted of 5 subscales corresponding to 5 age groups: 0,1-2,3-5,6-11 and 12-17 years old. Each scale included 4 primary indicators and 11 secondary indicators. The weight of primary indicators obtained by analytic hierarchy process is 0.28 for "environment", 0.16 for "product", 0.31 for "behaviors and skills", and 0.25 for "psychology". The highest weight of secondary indicators for "environment", "product" and "behaviors and skills" was "water area", while the top secondary indicators for "psychology" included "parental style""emotional control" "family atmosphere", with all indicators weighted higher than 0.2. Conclusion The Index System for Assessing Parent s Ability on Child Injury Prevention by Delphi consultation is comprehensive in content, and with the focus on parental behaviors and skills on injury prevention.

Objective: To investigate child injury prevention practice and associated factors among parents of primary school students. Methods: Parents of 2 577 students were selected from three primary schools in three administrative regions of Shanghai by multi stage sampling method between May and June in 2021. Questionnaire survey was administered to parents based on the Index System for Assessing Parent s Ability on Child Injury Prevention, which was developed previously by the present research group. Results were converted into standardized scores for descriptive analysis, and the original scores were analyzed by multiple linear regression model. Results: The standardized scores of parents on environment safety, product safety, behaviors and skills and psychological safety were (0.91±0.08)(0.93±0.08)(0.97±0.04)(0.95±0.05), respectively. The standardized score of general ability was (0.95±0.04). The standardized scores on knowledge, attitude and practice of injury prevention were (0.99±0.03)( 0.97± 0.05)(0.89±0.10), respectively. Mothers performances were generally better than fathers . Parents with higher education performed better than those with lower education. Parents with "being a parent" in mind performed better on child injury prevention. Conclusion There is a gap between practice with the knowledge as well as attitude towards child injury prevention among parents of primary school students. Parenting role, educational background and parental awareness of the importance of parental role are primary factors that affect child injury prevention practice.
