Objective
To develop a nurse medication unsafe behavior scale, so as to provide an effective tool for evaluating nurses' unsafe behaviors and provide scientific basis for the safe medication management of clinical nurses.
Methods
From July to August 2016, a semi-structured interview was conducted among 5 nursing managers and 5 clinical nurses from an affiliated hospital of a medical university in Harbin city selected by purposive sampling method. The initial scale was formed by analyzing semi-structured interview data, combining with relevant literature. From November to December 2016, a pre-test was conducted among 380 nurses from an affiliated hospital of a medical university in Harbin city, who met the inclusion criteria, selected by convenience sampling method, by pre-test version of the scale. A large sample test scale was formed by expert review and pre-test. From January to February 2017, a total of 1 243 clinical nurses from 2 medical university affiliated hospitals, 2 provincial class Ⅲ grade A hospitals and 1 municipal class Ⅲ grade A hospital were selected by convenience sampling method for a large sample test, and the reliability and validity of the scale were tested to form the final scale.
Results
The nurse medication unsafe behavior scale consisted of 4 factors (treatment of medical orders, medication preservation and dispensing, medication administration and medication monitoring) and 25 items. The cumulative variance contribution rate was 60.897%. Confirmatory factor analysis showed that the fit indexes χ2/df, GFI, CFI, IFI and RMSEA were 2.872, 0.922, 0.951, 0.951 and 0.050 respectively. The content validity index was 0.96. The Cronbach's α coefficient and split half were 0.935 and 0.841 respectively.
Conclusions
The nurse medication unsafe behavior scale has good reliability and validity. It can be used as a valid tool to measure nurse medication unsafe behavior.
