Background The validity of instruments is crucial in ensuring that data collected are sound and that these data represents what the instrument claims to measure. When an instrument is revised or used in a different population it is useful to re-examine its construct validity. Aim: To test the psychometrics properties of an instrument - the revised Families’ Importance In Nursing Care - Nurses’ Attitudes, designed to measure nurse’ attitudes towards involving family in nursing care in an adult acute care setting. Design and methodology A cross-sectional survey design was used in April - May 2016 with a sample of Enrolled and Registered Nurses (N = 212) to test the factor structure of the revised Families’ Importance In Nursing- Nurses’ Attitudes instrument. The instrument had 26 items with a five-point Likert response scale. Principle components analysis and exploratory factor analysis were performed with oblique rotations to assess the internal structure of the instrument. Setting A regional referral hospital in Queensland, Australia. Results Using Principal Components Analysis and Principal Axis Factoring we obtained the same factor structure to that originally identified for the instrument. Our results suggested the removal of six items to refine the instrument and achieve simple structure. Conclusion The removal of several items, relabeling of factors and residual cross-loading issues suggests that further revisions to the instrument are needed. This article is protected by copyright.
