(2012) Validity and reliability of the Turkish version of the Essentials of Magnetism Scale (EOM II). International Nursing Review 59, 570–576 Aim: To test the validity and reliability of the Turkish version of the Essentials of Magnetism II Scale (EOMII) for use by staff nurses as being essential to quality patient care. Methods: This study consisted of 385 nurses from four joint commission internationally accredited hospitals. The EOMII scale was translated using a back-translation technique. The statistical analysis was carried out using Cronbach’s alpha to test the internal consistency of the scale, while the factor analysis was carried out using the principal component analysis together with the varimax rotation and Kaiser normalization to test its construct validity. Results: The total mean scores of all the items of the scale were found to be 155.33 (minimum 77 – maximum 219) and the standard deviation was 29.45. All the items showed a statistically significant correlation (P < 0.01). The Cronbach’s a of the scale was 0.92, indicating a high level of reliability. Cronbach’s alpha consistencies in subgroups were between 0.87 and 0.70. In this study, job satisfaction and quality results show the sign of convergence as in the original scale, which shows that the scale has a high construct validity (P < 0.01). Discussions: Transcultural differences in the quality of nursing services can only be compared with reliable and valid instruments. This study shows that the Turkish version of the EOMII scale is a valid and reliable instrument to assess the nurses’ working environment and to provide quality patient care in Turkey.

These stem from the greater use of new technology, off-shoring some services to developing countries, advances in medical knowledge, an aging population, more informed and critical users of the healthcare system, and efforts by governments to further the control of healthcare expenditures (Carney 2010; Notara et al. 2010). Nurses play a pivotal role in shaping health policy in any country by seeing the gaps in the healthcare systems and assess- ing their consequences. They see where improvements are needed to increase access, promote prevention, coordinate care, and improve the quality and efficiency of health care. Studies show that nurses have influence in a large number of areas including: reduction of medical errors; improvement of patient safety and quality of care; promotion of wellness and expanding preventive care; improvement of health care efficiency and the reduction of costs; coordination of care through the healthcare system; assistance towards the healthcare system adapting to an Correspondence address: Sezer Kisa, Department of Nursing, Faculty of Health Sciences, Gazi University, Etiler, Ankara 06330, Turkey; Tel: 90-312-216-2622; Fax: 90-312-216-2636; E-mail: sezer@gazi.edu.tr.
