Validation of Filipino version of a questionnaire on work- related asthma among healthcare workers of the Philippine General Hospital: A prospective cross-sectional study

ABSTRACT

Objective@#This study aims to validate a Filipino version of the questionnaire by Delclos et al on occupational risk factors and asthma among the health care workers of the Philippine General Hospital.@*Methodology@#Forward and backward translation method for bilinguals was used in this study. The Filipino translation was administered to 110 health care workers selected by stratified random sampling. After 24 hours, the retranslated English version was given to the same respondents. Testing for internal consistency reliability was done by computing for Cronbach's alpha. Construct validity was subsequently determined using the Cramer's V Coefficient.@*Results@#The Filipino questionnaire showed good internal consistency reliability, as shown by the overall Cronbach’s alpha of 0.9016, which is comparable to that of the original version by Delclos. Likewise, our Filipino questionnaire showed good construct validity, supported by the Cramer’s V coefficients ranging from 0.2204 (strong relationship) to 0.7843 (very strong relationship).@*Conclusion@#Overall, the Filipino version of the questionnaire for work-related asthma tested among the health care workers of Philippine General Hospital showed good reliability and validity. This may now be used as screening tool for occupational asthma among health care workers who are at risk of developing the disease. In addition, this research tool may be utilized to establish the prevalence of occupational asthma in hospitals and later on, aid in the development of a better working environment for the whole health care team.
