Development and assessment of validity and reliability of the Persian version of vestibular rehabilitation benefit questionnaire
Background and Aim: Assessment of vestibular rehabilitation outcomes is a necessary step in this process. Assessment by clinical devices can reveal and measure some aspects of intervention but cannot show its effects on the patient quality of life. Vestibular rehabilitation benefit questionnaire is a scale for evaluating the effects of vestibular deficits on the quality of life and psychological aspects more efficiently than similar questionnaires. This research studied preparation and assessment of validity and reliability of Persian version of this questionnaire.
Methods: The translation process was based on International Quality Of Life Assessment protocol with considering cultural adaptation. Face validity and content validity, including content validity ratio and content validity index (CVI) were evaluated and test-retest reliability and Cronbach alpha was measured for reliability assessment of 108 vestibular deficit patients who received vestibular rehabilitation interventions. Furthermore, dizziness handicap inventory was used to evaluate correlation between vestibular rehabilitation benefit questionnaire and dizziness handicap inventory results.
Results: Questions with imperfections were modified. CVI in Lawshe method was equal to 1 indicating the necessity of inserting some questions in the questionnaire. Intraclass correlation was 0.94 for the test-retest reliability and the Cronbach alpha was 0.68, i.e. Persian vestibular rehabilitation benefit questionnaire has good reliability. In addition, the Spearman correlation coefficient was 0.74, indicating a good correlation between two questionnaire scores.
Conclusion: Persian version of vestibular rehabilitation benefit questionnaire is as reliable and valid as its original version and can be used for patients with vestibular deficits under vestibular rehabilitation treatment.
