Abstract

Objectives: To translate and validate the Vietnamese version of The Patient – completed Asthma Knowledge Questionnaire (PAKQ). Methods: Translation and cross-cultural adaptation of the PAKQ into Vietnamese based on the guidelines of Beaton et al. were undertaken in five stages: forward translation, synthesis, back translation, expert committee review, pilot testing with 35 patients with asthma. Subsequently, a cross-sectional study was conducted on 345 patients with asthma at the University Medical Center in Ho Chi Minh City, Vietnam. Internal consistency was evaluated using Cronbach’s alpha and Corrected Item – Total Correlation. Test- retest was assessed over the two-week interval by using the intraclass correlation coefficient (ICC) among patients who had their asthma condition or treatments unchanged during the interval. Results: The mean scores of the four criteria demonstrated good equivalence to the original version of PAKQ: semantic (0.99); idiomatic (0.99); experiential (1.00) and conceptual equivalence (1.00). Cronbach’s alpha coefficients were acceptable for the whole questionnaire (0.933) and for individual domains: About asthma (0.793); Asthma triggers (0.790); Diagnosis and management (0.849); Treating asthma (0.582). The translated PAKQ achieved good test-retest repeatability with an ICC of 0.913 for the total score and ICCs for the four individual domains > 0.8 (0.852, 0.850, 0.857 and 0.801). Conclusion: The Vietnamese version of PAKQ can be considered as a reliable questionnaire to evaluate the knowledge of adult patients with asthma in Vietnam.
