Adaptation of the Oral Aesthetic Subjective Impact Score (OASIS) Questionnaire for Perception of Oral Aesthetics in Brazil

Pimenta, Wladimir Vinicius / Traebert, Jefferson

Purpose: The aim of the present study was to assess the cross-cultural adaptation and reliability and validity of the Oral Aesthetic Subjective Impact Score (OASIS) for the perception of oral aesthetics in Brazilian adolescents. Materials and Methods: The cross-cultural adaptation was developed in agreement with internationally recommended methodology. The psychometric properties were assessed by application of the Brazilian version of the OASIS in 304 adolescents aged 13 to 19 years who were enrolled at two public schools and one private school in Tubarão, Brazil. The internal consistency of the instrument was measured using Cronbach’s alpha. The reliability was estimated through stability and homogeneity, using the Intraclass Correlation Coefficient and the Bland–Altman agreement. Validity was determined by comparing the OASIS-Brazil with the aesthetic component of the instrument Oral Impact on Daily Performance (OIDP) using the Spearman Rank Correlation Coefficient. Results: The internal consistency obtained was 0.52. Inter-observer and intra-observer correlations were strong, 0.87 and 0.83, respectively. The correlation with the aesthetic part of OIDP was 0.44. Conclusions: The results showed that the process of cross-cultural adaptation was successful and the adapted instrument showed good psychometric properties.
