Theory of mind in schizophrenia: correlation with clinical symptomatology, emotional recognition and ward behavior
1Department of Counseling Psychology, Seoul Cyber University, Seoul, Korea. wisemind96@iscu.ac.kr
Introduction:
Several studies have suggested the presence of a theory of mind (ToM) deficit in schizophrenic disorders. This study examined the relationship of emotion recognition, theory of mind, and ward behavior in patients with schizophrenia.
Methods:
Fifty-five patients with chronic schizophrenia completed measures of emotion recognition, ToM, intelligence, Positive and Negative Syndrome Scale (PANSS) and Nurse's Observation Scale for Inpatient Evaluation (NOSIE).
Results:
Theory of mind sum score correlated significantly with IQ, emotion recognition, and ward behavior. Ward behavior was linked to the duration of the illness, and even more so to theory of mind deficits. Theory of mind contributed a significant proportion of the amount of variance to explain social behavior on the ward.
Discussion:
Considering our study results, impaired theory of mind contributes significantly to the understanding of social competence in patients with schizophrenia.
