Abstract:
To study reliability and validity of PWl, this newly developed self-administered questionnaire which measures stress, was given to medial students. All respondent(133) were followed 4 weeks later and 92 were retested. Cronbach's a coefficient of data was 0.93. Test-retest reliability measured by pearson's correlation coefficient was 0.72(p<0.01l). Exploratory factor analysis(EFA) performed by principal axis factor method without iteration and by varimax rotation explored 13 principal components(eigenvalues > l). After exploring 4 factor structure according to previous study results, factor 1 showed good agreement but other factors did not. Confirmatory factor analysis(CFA) showed poor fit of 4 factor model to data. In the further study, it may be considered to model that has unidimensional factor structure.
