title: Validation of the Parental-Caregiver Perceptions Questionnaire: agreement between parental and child reports.
abstract: OBJECTIVE
  To test the validity and reliability of Brazilian Portuguese version of the Parental-Caregiver Perceptions Questionnaire (P-CPQ) (Aim 1) and to assess the agreement between parents and children concerning the child's oral health-related quality of life (OHRQoL) (Aim 2).
  
  
  METHODS
  The P-CPQ and the Brazilian Portuguese versions of the Child Perceptions Questionnaires (CPQ8-10 and CPQ11-14 ) were used. Objective 1 addressed in the study that involved 210 (validity and internal reliability) and 20 (test-retest reliability) parents and Objective 2 in the study that involved 210 pairs of parents and children. Construct validity was calculated using the Spearman's correlation and the Mann-Whitney/Kruskal-Wallis tests. Reliability was determined using Cronbach's alpha and intraclass correlation coefficient (ICC). Agreement between overall and subscale scores derived from the P-CPQ and CPQ was assessed in comparison and correlation analyses.
  
  
  RESULTS
  The P-CPQ discriminated among the categories of malocclusion and dmft. The P-CPQ showed good construct validity, good internal consistency reliability, and excellent test-retest reliability. There was systematic under- and overreporting in parents' assessments for younger and older children, respectively. However, the magnitude of the directional differences was just small. At individual level, agreement between parents and children was excellent. However, it ranged from excellent to moderate or substantial in subscales for CPQ8-10 and CPQ11-14 groups, respectively.
  
  
  CONCLUSIONS
  The Portuguese version of P-CPQ is valid and reliable. Some parents have limited knowledge about child OHRQoL. Given that parental and child reports measure different realities concerning the child's OHRQoL, information provided by parents can complement the child's evaluation.
