Psychometric evaluation of the German version of the instrument: Families’ Importance in Nursing Care – Nurses’ Attitudes (FINC‐NA)

Abstract

The involvement of families in care has long been advocated for acute and critical care settings to improve quality and safety of care. Nurses' attitudes towards families influence the way they involve and partner with families in the planning and delivery of care. Therefore, instruments with proven psychometric properties are necessary to assess the attitudes of nurses towards involving families in nursing care. To cross-culturally adapt and psychometrically test the German version of the Families' Importance in Nursing Care - Nurses' Attitudes (FINC-NA) scale with acute and critical care nurses. A cross-sectional study was carried out with 316 acute-critical care nurses, who filled in the FINC-NA between December 2016 and May 2018. Exploratory factor analysis was performed to assess structural validity. Internal consistency and homogeneity were determined using Cronbach's alpha. The four-factor structure of the FINC-NA - family as partner in care, family as resource in nursing care, family as their own resource and family as burden - was confirmed in the German version. Due to low primary and multiple loadings, seven items were removed. Moreover, five items loaded on different factors than the original version. Cronbach's alpha of factors ranged between 0.68 and 0.86. The cross-cultural adaptation and psychometric testing of the German version of the FINC-NA resulted in a 19-item scale that measure nurses' attitudes towards the importance of families in nursing care. Further testing is needed to refine the structural validity and establish construct validity of the FINC-NA German version.
