ABSTRACT Aim This study was to establish a scientific and sensitive index system of the biosafety incident response competence for clinical nursing staff to provide a reference for the evaluation of nurses' biosafety incident response competence. Design A modified recommendation for the conducting and reporting of Delphi studies was used to guide this study. Methods According to the literature review, preliminary biosafety incident response competence indicators for nursing staff were established, and an expert survey questionnaire was designed. The evaluation system for clinical nurses' biosafety incident response competence indicators was determined using the Delphi method. Results After two‐round Delphi survey, 28 nursing specialists from six provinces and cities around China, with expertise in three prevention research, epidemiology, military health service and biosafety incident rescue, established the index system of the biosafety incident response competence for nursing staff from April to May 2023. The final index system of the biosafety incident response competence was composed of four primary indicators, namely, biosafety incident preparedness, monitoring competence, protection ability and nursing disposal abilities; 10 secondary indicators and 49 tertiary indicators. The effective recovery rates of the two rounds of expert survey questionnaires were 93.33% and 100%, respectively. The authority coefficient, judgement coefficient and familiarity degree of Delphi experts were 0.877, 0.911 and 0.843, respectively. The Kendall's harmony coefficients of the two rounds of expert consultation were 0.301–0.384 and 0.401–0.424, respectively, with statistical significance (p

Abstract Aims This study was designed to develop a biosafety incident response competence scale and evaluate its validity and reliability among clinical nurses. Design This study employed a sequential approach, comprising four phases: (1) the establishment of a multidimensional conceptual model, (2) the preliminary selection of the items, (3) further exploration and psychometric testing of the items, (4) the application of the scale among clinical nurses. Methods The biosafety incident response competence conceptual model was developed through literature review and the Delphi method. A total of 1,712 clinical nurses participated in the preliminary items selection, while 1,027 clinical nurses were involved in the further psychometric testing from July 2023 to August 2023. The item analysis, exploratory factor analysis and confirmatory factor analysis were conducted to evaluate the construct validity. Reliability was measured using Cronbach’s alpha, split-half reliability, and test-retest reliability, while validity analysis included content validity, structural validity, convergent validity, and discriminant validity. From September to November 2023, we conducted a survey using the established scale with a total of 4338 valid questionnaires collected. T-test and variance analysis was employed to determine potential variations in biosafety incident response competence based on participants characteristics. Results The final scale is composed of 4 factors and 29 items, including monitoring and warning abilities, nursing disposal abilities, biosafety knowledge preparedness, and infection protection abilities. The explanatory variance of the 4 factors was 75.100%. The Cronbach’s alpha, split-half reliability and test-retest reliability were 0.974, 0.945 and 0.840 respectively. The Scale-level content validity index was 0.866. The Average Variance Extracted of the 4 factors was larger than 0.5, the Construct Reliability was larger than 0.7, and the Heterotrait-Monotrait ratio were less than 0.9. There were significant differences in the scores of response competence among nurses of different ages, working years, titles, positions, departments, marital status and participation in biosafety training (all P

Conclusions: The biosafety incident response competence scale for nurses exhibits satisfactory reliability and validity, making it a valuable tool for assessing clinical nurses’ abilities in responding to biosafety incidents.
