title: Validity and reliability of the Turkish version of the Essentials of Magnetism Scale (EOM II).
abstract: OBJECTIVE
  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 α 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).
  
  
  CONCLUSIONS
  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.
