ABSTRACT
Objectives:
To shorten the 24-item Arabic Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ(A)) for adolescents in Yemen. Material andmethods:
Two shortening methods derived six-item and nine-item versions the item impact method selected items with the highest impact scores as rated by 30 participants in each subscale; and the regression method was applied using data of 385 participants from the PIDAQ(A) validity study, with the total PIDAQ(A) score as the dependent variable, and its individual items as the independent variables. The four derived versions were assessed for validity and reliability.Results:
The means of the six-item and nine-item short versions of both methods were close. Cronbach's alpha values extended from 0.90 to 0.92 (intra-class correlations = 0.85−0.88). In criterion validity, strong significant correlations were detected between scores of all short versions and the 24-item PIDAQ(A) score (0.96−0.98; p < 0.001). Construct validity displayed significant associations among all short versions and self-perceived dental appearance rank and self-perceived need for orthodontic braces rank (p < 0.05). Mean scores of all short versions were significantly different between adolescents with severe malocclusion and those with slight malocclusion in discriminant validity tests. In conclusion, all PIDAQ(A) short versions are valid and reliable.
