Validity and Reliability of The Persian Version of The Short-Form Child Perceptions Questionnaire 11–14
Abstract BackgroundThe Child Perception questionnaire 11-14 (CPQ 11-14) is an efficient tool for assessment of oral health-related quality of life (OHRQoL). This questionnaire has been shortened to 16 items (CPQ11–14 ISF-16) to facilitate its use. The purpose the present study was to translate CPQ11–14 ISF-16 in the Persian language, culturally adapt and initially validate among adolescent population.Material and methodThe questionnaire was translated to Persian, back-translated to English and underwent cultural adaptation and pretesting. It was then filled out by 318 young adults (175 grils and 143 boys) between 11 to 14 years in Shiraz, Iran. The Persian version of CPQ11–14 ISF-16 along with the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) and two Suggested global questions were administered among participants to assess its Creition validity.ResultsFactor analysis extracted two domains and the factor loading of domains ranged from 0.423 to 0.837. Persian version of CPQ11–14 ISF-16 presented high internal consistency (Cronbach’s alpha = 0.854); It showed excellent criterion validity with PIDAQ (rho= 0.731, p < 0.001). There was a statistically significant positive moderate correlation between CPQ11–14 ISF-16 and its factors 1 and 2 and two global questions (first global question: rho= 0.439, p < 0.001; second global question: rho= 0.457, p=0.035)ConclusionThe Persian version of CPQ11–14 ISF-16 has optimal validity and reliability in a general population of 11–14-year-old Persian children.
