摘要

Background

The Brazilian version of the Quality Care Questionnaire – Palliative Care (QCQ-PC) is an instrument developed to assess the quality of care provided in palliative care.

Objective

To structurally validate the Brazilian version of the QCQ-PC for use in individuals with HF eligible for palliative care.

Methodology

This study aimed to structurally validate the QCQ-PC, following the Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN). Data were collected using the QCQ-PC, 36-Item Short Form Health Survey Instrument (SF-36), and Minnesota Living with Heart Failure Questionnaire (MLHFQ). Internal consistency was calculated using Cronbach’s alpha and, structural validity was assessed using confirmatory factor analysis (CFA). Construct validity was assessed by correlations between QCQ-PC and SF-36.

Results

The study sample (n = 113) consisted predominantly of middle-aged to older adults mainly classified as NYHA class I (36.3%) or III (32.7%). The structural validity of the two-domain of the QCQ-PC was confirmed by adequate fit indices: χ²/df = 1.46; CFI = 0.979; TLI = 0.971; RMSEA = 0.064; SRMR = 0.067; and with factor loadings ≥ 0.30. Construct validity was demonstrated by correlations of less than 0.30 between the QCQ-PC and SF-36 domains. Reliability was adequate, with ICC values ​​above 0.80 for both domains, measurement error less than 10%, and Cronbach’s alpha greater than 0.70.

Conclusion

The internal structure with two domains is the most suitable for use in individuals with FH eligible for palliative care through the QCQ-PC. The constructs are valid and reliable, with adequate internal consistency.
