Abstract:
OBJECTIVE: The aim of this study was to test the psychometric properties of Korean version of 10 items of Drug Attitude Inventory (KDAI-10). METHODS: A total of 157 stabilized schizophrenic patients were entered into the study after completion of screening tests. They completed the KDAI-10. And then they were interviewed with various scales such as Subjective Response Scale (SRS), Positive and Negative Syndrome Scale (PANSS), Extrapyramidal Side Effects Rating Scale (ESRS), and Global Assessment of Functioning (GAF). Correlations of KDAI-10 with these scales were tested. RESULTS: The Cronbach's alpha used to measure the internal consistency of the scale, was high (0.83). Principal component analysis with varimax rotation produced 2 factors, which explained 50.37% of the total variances. The First factor including 6 items was the positive subjective feelings and the second factor including 4 items was the negative subjective feelings, which were identical to the original authors'. Individual item correlations with total scores were all statistically significant (r=0.48-0.72, p<.001). And correlations of KDAI-10 with SRS, PANSS, ESRS and GAF showed that they were significantly correlated. CONCLUSION: Although the results were not quite satisfactory, KDAI-10 was demonstrated to have good reliability and construct validity.
