Adult Intelligence Scale-Korean version, Positive and Negative Syndrome Scale, and Social Problem
Solving Scales were administered to all patients, both before and after the training program.
Results:In the arithmetic scores(F=6.35, af=1, p=0.018) of Wechsler Adult Intelligence Scale-
Korean version, and total scores(F=6.35, af=1, p=0.018) and problem solving skill scale scores
(F=4.88, af=1, p=0.036) of social problem solving scale, interaction effects of training was
significant.
