非急诊科护士临床急救能力测评问卷的信效度检验

Reliability and validity of assessment questionnaire on clinical first-aid ability of nurses in non-emergency department

目的 检验非急诊科护士临床急救能力测评问卷的信效度,为下一步非急诊科护士临床急救能力水平的评估提供科学测评工具.方法 采用一般资料问卷、非急诊科护士临床急救能力测评问卷对1008名护士进行问卷调查,采用分半信度、内部一致性信度、重测信度进行问卷信度检验,采用内容效度、结构效度进行效度检验.结果 该问卷的Cronbach＇sα系数、折半信度系数、重测信度系数分别为0.927、0.861、0.977,各维度之间的相关系数值在0.298~0.810之间,各维度与总分之间的相关系数在0.534~0.947之间,运用主成分分析的方法最终选取5个因子,累计方差贡献率为58.28%.结论 经验证,该问卷具有较好的信度和效度,结构合理,可作为非急诊科护士临床急救能力的测评工具.

Objective To investigate the reliability and validity of the assessment questionnaire on clinical first-aid ability of nurses in non-emergency department and provide a scientific tool for the evaluation of clinical first-aid ability of nurses in non-emergency department. Methods General information questionnaire and the non-emergency department nurses＇ clinical first-aid ability assessment questionnaire were applied on 1008 nurses. Split-half reliability,internal consistency reliability and retest reliability were used to test the reliability of the questionnaire. The content validity and structure validity were applied to test the validity. Results The Cronbach＇s α coefficient,split-half reliability coefficient and retest reliability coefficient of the questionnaire were 0.927,0.861 and 0.977. The correlation coefficients among the various dimensions were from 0.298 to 0.810. The correlation coefficients between dimensions and total score were from 0.534 to 0.947. Exploratory factor analysis was performed to select five factors. The cumulative variance contribution rate was 58.28%. Conclusions The questionnaire has good reliability and validity with reasonable structure. It can be used as a tool to assess clinical first-aid ability of nurses in non-emergency department.
