Objective：In the patients with schizophrenic disorder, lack of insight might have a direct effect on the prognosis and which lead to an overall decline in his social cue perception. And, the social cognition abilities in the schizophrenic patient, especially the perception of emotions, are proposed as important variant factors in his/her handicap in social function. However, there is currently a lack of studies that directly explore the relationship between insight and social cue perception, and no relationships between the two have been established. This study seeks to focus on the relationship between the schizophrenic patient’s abilities in the perception of emotion and his/her insight.
Methods：In this study, a total of 29 subjects, all of whom were patients that had been diagnosed with schizophrenia, were evaluated with the Korean version of the SUMD-K(The Scale to Assessment Unawareness of Mental Disorder：Korean Version), a method recognized in its validity and reliability to measure the subjects’ insight. To measure the social cue perception of the subjects, the study utilized an evaluation method called the Korean-Social Cue Recognition Test-Revised(K-SCRT-R), which uses 8 stages：positive-middle arousal, positive-high arousal, negative-middle arousal, and negative-high arousal to assess the subjects.
Results：There seemed to be no correlation between the SUMD-K score and age, years of education, IQ, and the negative symptom score in PANSS. However, the SUMD-K score had a moderate positive correlation with the positive symptom score in PANSS(r=.419, p<.05), and a significant negative correlation with the GAF score(r=-.568, p<.01). The score in negative-high arousal, a part of K-SCRT-R, had a significant negative correlation with the negative symptom score of PANSS(r=-.518, p<.01). Particularly, the SUMD-K score showed a significant negative correlation with the negative-high arousal stage(r=-.501, p<.01).
Conclusion：Although for schizophrenic patients, the more severe the positive symptoms are, the more they suffer from lack of insight, there was no direct correlation between the positive symptom and the social cue perception ability. However, out of the social cue perception abilities, the decrease in perception ability in the negative high-arousal stage had a high correlation to the lack of insight, and the negative symptoms also had a high correlation with the perception ability in the negative-high arousal stage. Therefore, even though the severity of positive symptoms is related directly to the lack of insight, it did not show a direct relation to the decline in social cue perception ability. Rather, considering that the severity of the negative symptom, which has no direct relation to the lack of insight, has a strong relation to the decline in social cue perception abilities in the negative-high arousal stage, the schizophrenic patient’s
social cue perception ability, especially his ability in the negative-high arousal stage, is likely to be due to the structural changes in the brain that result in negative symptoms and decline of insight.
