Test-retest reliability and responsiveness of a Malay tinnitus questionnaire

ABSTRACT

Introduction: Tinnitus is a common complaint amongpatients with ear diseases and can be serious if not treated.Recently, a Malay tinnitus questionnaire, known as the“Borang Evaluasi Soal selidik Tinnitus” (BEST) had beendeveloped and preliminarily validated among Malayspeakingpopulation. The aims of the present study were todetermine the test-retest reliability and responsiveness ofthe BEST questionnaire.Method: Forty-six Malay adults (aged 23-74 years) withtinnitus were enrolled. They were instructed to fill in theBEST questionnaire accordingly. After one week, 21 of themwere asked to fill in the questionnaire again. The other 25subjects underwent tinnitus intervention for three monthsand following this; the BEST was administered to themagain.Results: In the test-retest reliability task, the intraclasscorrelation values obtained were acceptably high (0.70-0.90).After the intervention, significant differences in the BESTresult were found in the mind domain, main domain andcomposite score (p<0.05) with moderate effect sizes (0.61-0.70).Conclusion: The test-retest reliability of the BEST was foundto be good. It also showed good responsiveness tointervention. The clinical usefulness of the BEST inassessing patients with tinnitus was further supported bythe present study.nnaire; reliability; responsiveness; effect size
