Review and assess of frequently used scales in OHRQoL

Abstract

Introduction: Cross-cultural adaptation is increasingly important in order to understand human behavior, health and psychological processes. Adaptation refers to assessing a similar item in a different culture. Guillemin et al. (1993) and Acquadro et al. (2008) recommend the following: care should be taken during cross-cultural adaptation to incorporate a team of varied experts, there should be regular contact with the original authors to minimizemajor errors and a pilot study should be conducted for new items before they are submitted to a larger group. Aims of study: Review and evaluate cross-cultural adaptation of frequently used measures of OHRQoL in adult and children. Method: Online search engines were searched including MEDLINE, PubMed, EMBASE and the Cochrane Library for the articles from 1997 to 2016 using pre-determined inclusion and exclusion criteria. Articles reviewed by titles, abstracts, and then full-text articles for their relevance to this review. Then the most commonly used models were identified reviewed and summarized in tables. Results: According to our review in this study the most common cross-cultural adaptations measure of OHRQoL for adults and child OHRQoL were assessed and evaluated. Most of the studies were used forward and back translation. However only few studies were used other criteria such as committee review, qualitative interview and pretest stage. Tables A and B shows detail of our results. Conclusion: In conclusion, this review of the cross-cultural adaptation of measures of oral health related quality of life has demonstrated that very few studies met all the criteria for a valid cross cultural adaptation of a measure. They recommend that in order to adapt questionnaires, researchers should follow a multi-step method including forward translation, back translation, committee review, and qualitative interviews and pretesting.
