Abstract
Objective
To assess the construct validity and internal reliability of the Brazilian version of the scale Families’ Importance in Nursing Care–Nurses’ Attitudes (FINC-NA).
Methods
This is a methodological study, whose data were collected in November 2019, with 283 nurses, working in three university hospitals in the state of Paraná. Cronbach’s α coefficient was used to determine internal consistency, exploratory factor analysis (EFA) in principal components, with Varimax rotation for construct validity. The relationship between observed variables and latent variables was assessed using confirmatory factor analysis (CFA).
Results
Participants had an average age of 40 years, most were married, female, and more than 30% had a master’s or doctoral degree. In EFA, five items were eliminated (correlation below 0.30). The final model retained three factors, explaining 52.2% of the data variance, which were theoretically reinterpreted. In CFA, the three factors showed a strong correlation (above 0.7); however, three more items were excluded. A cause-and-effect relationship was not confirmed between the three constructs, but it was confirmed that the items are reliable for measuring the three new dimensions after reinterpretation, as all factor loadings are greater than 0.5. The final validated instrument has 18 items distributed into three factors and a Cronbach’s α coefficient of 0.91.
Conclusion
The scale has satisfactory psychometric properties, demonstrating adequate evidence of validity and reliability.
