Validation of Hindi (Indian) version of the child perceptions questionnaire (CPQ11-14) among 11-14 year old School Children.

ABSTRACT

CONTEXT Oral health is a fundamental aspect of general health which significantly affects quality of life (QoL) of an individual. Oral health-related QoL is a multidimensional concept determined by race, education, culture, and experiences related to oral diseases. AIM: This study aims to evaluate the Hindi (Indian) version of the child perceptions questionnaire (CPQ11-14) among 11-14-year-old school children in Rohtak City, Haryana, India. MATERIALS AND METHODS: A cross-sectional study was carried out among 586 children in Rohtak city, Haryana, India, to find out the translation and cross-cultural adaptation of CPQ11-14. The original version of CPQ11-14was translated to Hindi language, and the dental caries experience was measured by caries assessment spectrum and treatment index. STATISTICAL ANALYSIS: The data were entered into Microsoft Excel and analyzed using SPSS 18. Reliability was assessed in 2 ways internal consistency reliability and test-retest reliability. The level of significance was set at 0.05. RESULTS: Construct validity was confirmed demonstrating statistically significant associations between total CPQ11-14 score and global ratings of oral health (P = 0.00) and overall well-being (P = 0.00). Mean CPQ11-14scores (20.30 ± 10.91) including all the domain scores were higher among children without dental caries when compared to children with dental caries (19.79 ± 9.88) and the instrument was not able to discriminate between two clinical groups significantly (P = 0.08). CONCLUSION: The Hindi version of the CPQ11-14 questionnaire is a reliable instrument having good reliability, good construct, and convergent validity but lacks discriminant validity. Shorter forms of CPQ11-14may be more useful when compared to original construct.
