Abstract
Aim: The psychometric impact of dental aesthetics questionnaire (PIDAQ) was designed for adults, and this study aimed to test its applicabitlity in adolescents in Croatia. Subjects and methods: Psychometric characteristics of the Croatian version of PIDAQ were tested on a sample of 191 examinees (60% girls) aged 11-17 years, who were reffered to the orthodontic practice for consultation or the therapy. Validation was performed according to the COSMIN criteria (COnsensus-based Standards for the selection of health status Measurment Instruments). The Index of Complexity, Outcome and Need (ICON) and the Index of Orthodontic Treatment Need (IOTN) were assessed intraorally. Results: PIDAQ domains have satisfactory internal consistency in adolescents (α ranging from 0.81 for Aesthetic Concern (AC) to 0.92 for Dental Self-Confidence (DSC); p<0.001) Average inter-item correlations in each domain were ranging from 0.46 for Social Impact (SI) to 0.64 for DSC. Spearman correlations representing convergent validity showed that domains are measuring similar constructs as satisfaction with teeth appearance (ranging from r=0.758 for DSC to -0.462 for SI; p<0.001). Reproducibility of reporting dimensions of PIDAQ in a 1-week interval without intervention was high, ranging 0.806-0.891 (p<0.001). PIDAQ domains were able to discriminate adolescents with high orthodontic treatment need (IOTN DHC ≥4 and ICON ≥4) from those with no or borderline need (p<0.05). In responsiveness testing PIDAQ dimensions were able to detect changes induced by the alignment of the teeth (p<0.001). Conclusion: Psychometric properties of the PIDAQ in adolescents in Croatia are similar to those in adults, confirming the instruments` applicability in adolescents.
