INTRODUCTION: This study aims to present the validation and cross-cultural adaptation of the Tonsil Adenoid Health Status Instrument (TAHSI) in Turkish language.
METHODS: This prospective single-center validation study was conducted between May 15th, 2019 and December 31st, 2019 in a tertiary care facility. The study group consisted of 41 patients (20 males, 21 females; mean age 6.8±3.2 years; range, 3 to 15 years) who were diagnosed with tonsil and/or adenoid disease who were scheduled for adeno/tonsillectomy, while the control group consisted of 42 healthy children (20 males, 22 females; mean age 9.5±3.8 years; range, 3 to 16 years). The original survey was translated to Turkish and cross-cultural adaptation process was carried out as stated in guidelines. Both groups were assessed twice in two to six weeks before surgery. Study group was assessed again six months following surgery. Internal consistency, test-retest reliability, validity, and responsiveness to change were analyzed.
RESULTS: Cronbach's alpha was 0.949 for the total scale. All subscales showed adequate internal consistency. Test-retest reliability was over 0.8 for all subscales. Subscale scores were statistically significantly lower in control group compared with study group (p<0.001). The scale showed high responsiveness to change for all subscales (p<0.001).
DISCUSSION AND CONCLUSION: Turkish version of TAHSI showed good psychometric properties and can be used for both research and clinical purposes in children with tonsil and adenoid disease.
