Development of a short form of the Brazilian Parental-Caregiver Perceptions Questionnaire using exploratory and confirmatory factor analysis

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.
