Oral Health-Related Quality of Life in Persian-Speaking Elementary Schoolers in Iran: A Psychometric Study of Child Perception Questionnaire

Abstract

Background and Purpose:The study aims to examine the validity and reliability of the impact of 16-item Short-Form Child Perception Questionnaire (CPQ11–14-ISF:16) in Persian-speaking elementary schoolers.Methods:From two main cities in Iran, 708 mother–child dyads were enrolled in 2018. Decayed, missing, and filled teeth (DMFT/dmft) indexes were examined for divergent validity. Two built-in indexes of overall oral health and overall impacted well-being were used for concurrent validity. Exploratory factor analysis (EFA) with Geomin rotation, Cronbach’s α, and Spearman’s correlation were executed.Results:The total Cronbach’s α was 0.71. EFA indicated CPQ11–14-ISF:11 (α = 0.66) to compose three eligible factors (α = 0.66), including oral problems (α = 0.54), emotional problems (α = 0.66), and social problems (α = 0.41). The concurrent/divergent validity of CPQ11–14-ISF:11 and the subscales was partially confirmed.Conclusions:The use of CPQ11–14-ISF:11 to multidimensionally address dental care for children requires further investigations.
