Validity and reliability of the Turkish version of the Child Perceptions Questionnaire 8-10

Area of Science:

• Pediatric Dentistry
• Oral Health Research
• Quality of Life Assessment

Background:

• Assessing oral health status in Turkish children is crucial for understanding its impact on quality of life.
• A reliable measurement tool is needed to accurately evaluate the oral health of this population.

Purpose of the Study:

• To translate the Child Oral Health Quality of Life Questionnaire (CPQ_8-10) into Turkish.
• To evaluate the reliability, validity, and reproducibility of the translated Turkish version of the CPQ_8-10.

Main Methods:

• The Child Oral Health Quality of Life Questionnaire (CPQ_8-10) was translated into Turkish.
• Test-retest reliability was assessed using the intra-class correlation coefficient (ICC) in 50 children.
• Internal consistency was evaluated using Cronbach's alpha in 418 children (aged 8-10).
• Construct and discriminant validity were examined using correlation analyses, exploratory factor analysis (EFA), and confirmatory factor analysis (CFA).

Main Results:

• The translated Turkish CPQ_8-10 demonstrated high test-retest reliability (ICC = 0.90) and internal consistency (Cronbach's alpha = 0.82).
• The questionnaire showed good construct validity, with significant correlations between CPQ_8-10 scores and oral health/overall well-being (r = 0.50, P < .001; r = 0.47, P < .001).
• Confirmatory factor analysis statistically verified seven factors identified by EFA.
• Discriminant validity was supported by significant differences in scores between the CPQ_8-10 and Oral Health Impact Profile (OHIS) (P < .001).

Conclusions:

• The Turkish version of the CPQ_8-10 is a reliable, valid, and reproducible instrument.
• This validated tool is suitable for assessing oral health-related quality of life in Turkish children aged 8-10.
• The findings support the use of the Turkish CPQ_8-10 in clinical and research settings within Turkey.
