Psychometric characteristics of nursing care complexity scale in medication errors, Iran

Twenty-first century challenges of nursing work is increasing complexity of care in the workplace. The most common medical errors that identified are medication errors. With changing patterns of health services, the complexity increases in all workplaces. The aim of study was assessing factor analysis, validity, reliability and psychometric characteristics of nursing care complexity scale in medication errors. In this study the scale translates by Wilde and colleagues model, 115 Iranian nurses were selected by convenience sampling method. Data was analyzed using SPSS-18. The age of nurses was 34.8± 7.87 years and almost them were female (n=78) and mean work experience in ward was 6.07±4.13 years. The factor analysis, rotated matrix determined 5 factors: 1) organizational technology, 2) client condition, 3) critical care condition,4) decision making methods and 5) creativity in care. Also reliability using Cronach s alpha coefficient showed moderate reliability of scale (α=0.61) and correlation coefficient in test- retest emerged (r=0.88). Although translations of care complexity scale in medical errors has satisfactory reliability and validity and can be used in the Iranian health system.
