The Hungarian adaptation and validation of the Osteoporosis Health Belief Scale

Introduction: In the international literature, several disease-specific questionnaires are available for many diseases. The opportunities of validated questionnaires are incomplete about osteoporosis in Hungarian language. Objective: The aim of the study was to validate the Osteoporosis Health Belief Scale (OHBS) into Hungarian that would make it possible to measure the osteoporosis-related attitude for Hungarian-speaking women. Method: The questionnaire was validated into Hungarian according to the six-step guideline outlined in 2000. The Osteoporosis Knowledge Assessment Tool (OKAT) questionnaire was used to examine external validity. Our sample consisted of 600 women. We performed descriptive statistics; Cronbach's alpha value was calculated for internal consistency, we calculated Spearman's correlation coefficient to examine external validity. We carried out factor analysis (Kaiser-Meyer-Olkin [KMO] test, Bartlett test) to examine whether the new questionnaire is suitable for measurements in the given language the same way as the original questionnaire. Results: Our sample (37.7 +/- 13.15 years of age) achieved low score for both OHBS (126.28 +/- 14.85) and OKAT (8.78 +/- 3.1). The Cronbach's alpha value was 0.802. Factor analysis (KMO = 0.886; Bartlett test p<0.001) identified 7 factors that can be similar to the original factors. During the test-retest, the Spearman correlation coefficient showed a value between 0.921 and 1.000. When comparing the OKAT and OHBS dimensions we found several significant relationships. Discussion: The results of the study are similar to the results of the original questionnaire validation as well as to other OHBS validation studies. Conclusion: Based on the results, we consider that the Hungarian form of the OHBS is a reliable and valid questionnaire.
