Italian Validation of the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ)
ABSTRACT
The Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) is a scale which measures aspects of the oral health-related quality of life. However, no Italian version of PIDAQ has been developed. The aim of this study was to translate the original English version of PIDAQ into Italian and to assess the validity and reliability of the Italian version for application among Italian adults. The questionnaire was translated into Italian, back translated, pre-tested, and cross-culturally adapted. Subsequently, the Italian version of PIDAQ and the Oral health impact Profile-14 (OHIP-14) were administered to 264 orthodontic patients aged from 18 to 83 years old, mean age was (38.39 + 16.9) belonging to Southern Italy. Cronbach’s alpha of the translated PIDAQ was 0.82, corrected item-total correlation ranged from 0.48 to 0.67. The 23 items of PIDAQ were divided into four domains. There was a logical relation among the items in the same domain and a highly significant association among scores of PIDAQ and the other scale. The translated Italian version of PIDAQ demonstrated good reliability and validity. Its sufficient discriminative and evaluative psycho-metric properties provide the theoretical evidence for further use in study on orthodontic-specific aspects of quality of life among Italian adults.
