[Validation of French translation of the "Tinnitus Reaction Questionnaire", Wilson et al. 1991]

Abstract

The present study proposes a validation of a french translation of the TRQ initially published by Wilson et al., for evaluating the psychological distress of tinnitus sufferers. The 26 items translated into french were used on a sample of 173 tinnitus sufferers, who also filled out the Mini-Mult, a short version of the MMPI proposed by Kincannon. Internal validity was demonstrated by strong correlations (i) between each item (except items 5 and 20) and total TRQ score (0.33 < or = r < or = 0.87, p < or = 0.0001), (ii) between each internal TRQ factor (0.58 < r < 0.81, p < 0.0001) and the others. Cronbach's alpha test also showed the questionnaire to have a good internal validity (alpha = 0.94). The external factors used for testing concurrent validity were the scores on depression, psychaesthenia and anxiety Mini-Mult scales. The strong correlations (one factor ANOVA and simple linear regression tests) between scores on depression and psychaesthenia scales and (1) each TRQ item, (2) each TRQ factor, (3) total TRQ scores, confirmed concurrent validity. Scores obtained on anxiety index showed high correlations only with TRQ score, factor 3 score and some TRQ items (most of them included in factor 3). The internal and concurrent validities of the French version of the TRQ justify the use of this questionnaire, with the reserve that items 5 and 20 appeared irrelevant for the measuring of tinnitus distress in French-speaking countries. Such a questionnaire should improve our knowledge of tinnitus' life-impact and enable detection of patients whose psychological distress necessitates rapid intervention.
