Refinement and Psychometric Reevaluation of the Instrument

Abstract

The instrument Families' Importance in Nursing Care--Nurses' Attitudes (FINC-NA) was developed to measure nurses' attitudes toward the importance of families in nursing care. The low variations in item responses, which affect the discrimination ability and unstable internal consistency, have been considered as limitations. The aim of this study was to refine and revalidate FINC-NA regarding score distribution, homogeneity, dimensionality, differential item functioning for gender, stability, and internal consistency. There were 246 registered nurses studying at advanced levels who answered the revised FINC-NA. The FINC-NA had five response alternatives. The findings showed that although some subscales still deviated from a normal distribution, the variability of the scores and the homogeneity was improved. In addition, the dimensionality was reproduced and minor problems with differential item functioning for gender were detected. All FINC-NA scales showed good reliability. The results allow the use of the revised FINC-NA in studies where an assessment of nurses' attitudes toward families' importance in nursing care is desired.
