Abstract
|
|
|
This study was conducted to develop and evaluate the reliability´, and the validity of a questionnaire in order to determine the applicability as a screening tool for estimating environmental exposure and health effects related to air pollution.
The questionnaire was developed with adopting some items of others such as ISAAC or ATS-DLD. And then we performed test-retest to 89 middle: school students and their mothers at interval of three months. Cohen´s Kappa values,?, weighted Kappa values, Spearman ´s correlation coefficients, and Pearson´s correlation coefficients for each item were computed as reliability coefficients. The validity coefficients and validity coefficient bounds were also obtained by simply using these reliability coefficients.
As results, Kappa ranged broadly from 0.10 to 0.61 of the items ´4iet´, 0.52---0.79 of the environmental tobacco smoke, 0.39---0.44 of the functional c4tegories of surrounding environment, and 0.54--0.63 of the using transportation systems; these item-s were regarded as confounding factors. For items related to health outcomes, Kappa ranged from -0.02 to 0.37 in the respiratory system of past medical hi$tory, and from 0.11 to 0.55 in the current health status. But Kappa of the others were over 0.60.
In conclusion, if some items can be corrected or modified, the questionnaire developed in this study can be used as a tool for evaluating environmental exposure and health effects associated with air pollution.
