Аннотация
OBJECTIVE: There are no instruments available to comprehensively assess health-related quality of life (HRQoL) in chronic otitis media (COM) in Italian-speaking countries. The Zurich chronic middle ear inventory (ZCMEI-21) is a well-established instrument for the assessment of HRQoL in COM. The objective of this study was to translate and cross-culturally adapt the ZCMEI-21 into Italian and validate this questionnaire for measuring HRQoL in patients with COM.
STUDY DESIGN: Prospective multicenter study.
SETTING: Three University hospitals (northern Italy, central Italy, southern Italy).
PATIENTS: Adult patients suffering from COM (n = 128).
INTERVENTION: Following international guidelines, the ZCMEI-21 was translated into Italian (ZCMEI-21-It). Validation was performed by psychometric test statistics. Moreover, ZCMEI-21-It total and subscale scores were compared and correlated with 1) the scores of the original validation study, 2) to a question that directly addresses HRQoL, and 3) to the scores of the EQ-5D-5L, a generic questionnaire assessing HRQoL.
RESULTS: From three study centers, a total of 128 patients with COM were included. Cronbach's α was 0.86 indicating a high reliability. Between the ZCMEI-21-It total score and the question that directly addresses HRQoL, we found a strong correlation (r = 0.62, p < 0.0001). Between the ZCMEI-21-It total score and the EQ-5D-5L scores, we expectedly found moderate correlations (descriptive system score: r = 0.39, p < 0.0001; visual analog scale: r = 0.30, p = 0.008).
CONCLUSION: We translated the ZCMEI-21 questionnaire into Italian and validated the ZCMEI-21-It in a prospective multicenter study. The ZCMEI-21-It is the first instrument that comprehensively assesses relevant dimensions of HRQoL in Italian-speaking patients affected by COM.
