Cross-Cultural Adaptation and Psychometric Properties of Osteoporosis Knowledge Tool-Arabic Version Among Iraqi Population

Translation and cross-cultural adaptation of Osteoporosis Knowledge Assessment Tool (OKAT) for Chinese populations in Australia

The increased prevalence of osteoporosis among Chinese-speaking communities in Australia deemed it necessary to have a culturally appropriate tool for assessing knowledge. This study describes the cultural adaption of the validated Osteoporosis Knowledge Assessment Tool (OKAT). The adapted tool is readable and understandable for diverse Chinese-speaking communities.

PURPOSE

With an expected increasing prevalence of osteoporosis among Chinese-speaking communities in Australia, a cross-culturally adapted questionnaire is necessary to assess knowledge levels among the group. We aimed to cross-culturally adapt the Osteoporosis Knowledge Assessment Tool (OKAT) questionnaire for Chinese-speaking populations in Australia.

METHODS

Cross-cultural adaptation guidelines were employed to culturally adapt the OKAT to simplified Chinese. This involved translation, revision, retroversion, and expert discussion before finalizing the Chinese version of OKAT. The participants were recruited through convenience sampling from a cohort of Chinese-speaking populations who attended a bone health promotion program. The adapted questionnaire was piloted with Chinese-speaking communities in the Greater Western Sydney area for face and content validity. The adapted questionnaire was compared with the original version for response agreement using Cohen's kappa goodness of fit. The face validity of the adapted tool was analysed through a binary scale rating for readability and understandability.

RESULTS

The cross-culturally adapted version of OKAT has a 71.8% total response agreement with the original version of OKAT. The cross-culturally adapted OKAT yielded higher total scores than the translated version. The cross-culturally adapted tool had a good face and content validity.

CONCLUSION

The cross-culturally adapted version of OKAT improves the overall readability and understandability of the questionnaire among Chinese-speaking populations in Australia.

Development and Validation of India-specific Hindi Version of Osteoporosis Knowledge Assessment Tool

Purpose

Patient education is one of the important components of reducing the morbidity of osteoporosis. The aim of this study is to validate the Hindi version of the Osteoporosis Knowledge Assessment Tool (OKAT-H) among a hospital-based sample in the age group of 18-44 years of age.

Methods

The study was conducted in two phases - translation and adaption of the OKAT in Hindi followed by its validation. The translated tool was analyzed by Flesch reading ease, McNemar test, Cronbach alpha, difficulty index, discrimination index, and principal factor analysis.

Results

Two hundred and sixty women with a mean age of 28.3 ± 17.2 years were enrolled in the study. The mean score of the OKAT-H tool obtained in the study was 11.3 ± 2.1. A significant difference was noted in the scores based on educational qualification or with any family history of either osteoporosis or fracture (P < 0.05). The Flesch score for the OKAT-H tool was 86. Inter-item correlation for all the items ranged between 0.15 and 0.5. The Cronbach's alpha measured 0.892 suggesting high internal consistency. Items number 6, 7, 8, 9, 13, and 14 showed a significant difference on the McNemar test questioning its consistency on test-retest.

Conclusion

A new shorter version of the tool may be developed since six items showed low consistency. The use of such an instrument in local language would help spread awareness about the disease as well as help the population in adopting osteoprotective strategies and also to seek help and advice regarding treatment.
