ABSTRACT

Objective To develop the instrument for inpatients involvement in patient medication safety,and to test the reliability and validity of the scale.Methods The draft scale was formulated by combining results of literature review,semi-structured interviews and Delphi expert consultation.Totally 461 inpatients in a tertiary hospital in Wuhan were selected for investigation to examine its reliability and validity.Results The final scale consisted of 3 dimensions and 23 items.The Cronbach's α coefficient was 0.916 for the total scale and ranged from 0.777 to 0.858 for 3 dimensions;Spearman-Brown coefficients of 3 dimensions varied from 0.740 to 0.843;the test-retest correlation was 0.742 for the total scale.The scale content validity index was 0.923,and the item content validity index ranged from 0.833 to 1.000.Factor analysis was used to extract 5 factors,and 3 factors were allowed according to the scree test.Therefore,the cumulative variance contribution rate was 51.191％ for 3 factors.Conclusion The Inpatients Involvement in Patient Medication Safety Scale has good reliability and validity.It can be used to evaluate inpatients' engagement behavior in medication safcty,and provide reference for quality management of nursing safety.
