Abstract:
Objective To investigate the impairment of intertemporal choices in adolescents with positive and negative schizophrenic symptoms.Methods 30 adolescent schizophrenia patients with positive symptoms (positive symptoms group),30 adolescent schizophrenia patients with negative symptoms (negative symptoms group)and 30 healthy controls were selected.All the subjects were investigated with intertemporalchoice Test.Results (1) Under now conditions ((37.22±30.92)%,(19.67±16.35)%,P<0.05)),notnow conditions ((35.74±31.69)%,(19.33± 18.07)%,P<0.05)) and overall condition ((36.48±30.44) %,(19.50± 13.82)%,P<0.05)),the ratio of later-large (LL) choice in negative symptoms group were significantly higher than those in the healthy controls.Under now conditions ((37.22±30.92) %,(20.37±22.33) %,P<0.05)),not-now conditions ((35.74± 31.69) %,(22.04±22.05) %,P< 0.05)) and overall condition ((36.48±30.44) %,(21.20±21.57) %,P<0.05)),the ratio of LL choice in negative symptoms group were significantly higher than those in positive symptoms group.There were no differences in the ratio of LL choice between positive symptoms group and healthy controls (P> 0.05).(2)Pearson correlation analysis showed that the Vocabulary Fluency Test of negative symptoms group was positively correlated with LL selection ratio under now conditions (r=0.411,P=0.024).Conclusion The ability of intertemporal choices in adolescents schizophrenia patients with negative symptoms is impaired remarkably,while this kind of ability is impaired unremarkable in adolescence with negative symptoms.The ability of intertemporal choices in adolescents schizophrenic patients with negative symptoms is correlated with cognitive executive function.
