In accordance with the findings of Seo et al. [37] and Woolfe [40], we found that the demographics and illness characteristics of the experimental group had no statistically significant effect in improving their social skills. This is consistent with the results of a previous study done by Liberman et al. [23] and could be explained as the people who think concretely have problems generalizing and implementing newly learned skills inreal-life situations when the impaired abstracting ability is due to schizophrenia, regardless of the phase or subtype of the illness, gender, level of education and hospitalization rate [39]. In addition, it is difficult for them to find and retain jobs, further isolating themselves from society [40, 41]. These poor social skills are closely related to repetitive recurrences of the disease and re hospitalizations and have been reported as important factors affecting prognosis [42].
