The present study is to evaluate the validity and reliability of Child Perception Questionnaire for ages 11–14 (CPQ11–14) with 37 items by means of Rasch Analysis in a group of Turkish population. 133 children aged 11–14 years old were included to the study. CPQ11–14 was administered at their first visit, as well as Facial Image Scale questions. After two weeks, CPQ11–14 was re-applied to a subgroup (n = 25) of the children. The construct validity of the CPQ11–14 data was assessed by using Rasch Analysis. Intraclass Correlation Coefficient was calculated with the CPQ11–14 scores of first and second visits. Cronbach's α coefficient was obtained for evaluating internal consistency. According to Rasch Analysis, mean item infit ± sd was 0.98 ± 0.25; mean item outfit ± sd was 1.08 ± 0.91. Item and person separation indices and reliabilities were calculated as 3.34 and 2.42; 0.92 and 0.85, respectively. The Pearson's correlation coefficient between the total scores of CPQ11–14 and the Facial Image Scale was found as 0.74 (p < 0.001). Cronbach's alpha coefficien...
