Abstract

Purpose

This study presents the Brazilian short form of the P-CPQ.

Methods

Data from a representative sample of 702 parents/caregivers of children were randomly divided in two subsamples. A development sample (n = 502) was used for exploratory factor analysis (EFA), and a validation sample (n = 200) was used for confirmatory factor analysis (CFA). The EFA was used to determine the hypothetical factor structure and internal consistency. The CFA was applied to test the factor structure of the original P-CPQ, alternative models and the validity and reliability of the Brazilian short form of the P-CPQ.

Results

A 3-factor model (alternative model 2) had a factor structure with high factor loadings, acceptable fit indices (χ2/df = 2.38; GFI = 0.90; CFI = 0.90; TLI = 0.87; AGFI = 0.85; SRMR = 0.07) and both convergent and discriminant validity (Pearson bivariate zero order correlations among factors <0.85).

Conclusions

The Brazilian P-CPQ with three subscales and 13 items appears to be a valid short version to be used in further studies to evaluate parents/caregivers’ perceptions of children’s oral health-related quality of life.
