Level of agreement between self‐administered and interviewer‐administered CPQ 8–10 and CPQ 11–14 . Community Dent Oral Epidemiol 2011. © 2011 John Wiley & Sons A/S Abstract – Objectives: The aim of the present study was to assess the psychometric properties and level of agreement between the self‐administered and interviewer‐administered Child Perceptions Questionnaire (CPQ) for children between 8 and 10 years of age (CPQ 8–10 ) and between 11 and 14 (CPQ 11–14 ) years of age. Methods: A randomized cross‐over study was carried out, involving 180 children (Group 1 – 90 children between 8 and 10; Group 2 – 90 children between 11 and 14 years of age) in the state of Minas Gerais, Brazil. All children completed both administration modes of the CPQ; half of each group received interviewer‐administered mode first [Subgroup A (CPQ 8–10 n = 45) and Subgroup C (CPQ 11–14 n = 45)], and the other half performed the self‐administered mode first [Subgroup B (CPQ 8–10 n = 45) and Subgroup D (CPQ 11–14 n = 45)]. Test–retest reliability of each mode of administration was tested on 60 children (30 for CPQ 8–10 ; 30 for CPQ 11–14 ), who were not included in the other analyses. The level of agreement between scores on the self‐administered and interviewer‐administered versions of the CPQ 8–10 and CPQ 11–14 was established using the intraclass correlation coefficient (ICC). The order of presentation of both instruments was tested considering the four subgroups (A, B, C and D). The calculation of effect size proposed by Cohen (1992) was used to test the clinical significance of the findings. Results: Both the self‐administered and interviewer‐administered versions of CPQ 8–10 and CPQ 11–14 demonstrated acceptable psychometric properties. Agreement between the administration modes for the CPQ 8–10 and CPQ 11–14 was 0.90 and 0.88 (ICC), respectively. With the exception of the functional limitation subscale, the scores of the subscales and overall score on the CPQ 8–10 were significantly higher in the group of children who responded to the interviewer‐administered measure first. With the CPQ 11–14 , statistically significant differences were found only for the emotional well‐being subscale. Conclusions: Both administration modes of the CPQ 8–10 and CPQ 11–14 demonstrated satisfactory psychometric properties and a high level of agreement. Although statistically significant differences were observed for oral symptoms, emotional well‐being and social well‐being, with the first administration of the interviewer‐administered version, the effect of the order of administration had small to medium effects on the CPQ scores.
