Abstract
OBJECTIVE
The study's aim was to develop and standardize a Korean version of the University of California San Diego Performance-based Skills Assessment (K-UPSA), which is used to evaluate the daily living function of patients with schizophrenia.
METHODS
Study participants were 78 patients with schizophrenia and 27 demographically matched healthy controls. We evaluated the clinical states and cognitive functions to verify K-UPSA's reliability and validity. For clinical states, the Positive and Negative Syndrome Scale, Clinical Global Impression-Schizophrenia scale, and Social and Occupational Functioning Assessment Scale and Schizophrenia Quality of Life Scale-fourth revision were used. The Schizophrenia Cognition Rating Scale, Short-form of Korean-Wechsler Adult Intelligence Scale, and Wisconsin Card Sorting Test were used to assess cognitive function.
RESULTS
The K-UPSA had statistically significant reliability and validity. The K-UPSA has high internal consistency (Cronbach's alpha, 0.837) and test-retest reliability (intra-class correlation coefficient, 0.381-0.792; p<0.001). The K-UPSA had significant discriminant validity (p<0.001). Significant correlations between the K-UPSA's scores and most of the scales and tests listed above demonstrated K-UPSA's concurrent validity (p<0.001).
CONCLUSION
The K-UPSA is useful to evaluate the daily living function in Korean patients with schizophrenia.
