[Objective]To investigate autistic traits(AT)of college students with different levels of pro-social behavior,and their characteristics of empathy and theory of mind(ToM).[Methods]372 college students(91males)were recruited. The Chinese Version of Autism-Spectrum Quotient(AQ-C)and Prosocial Tendencies Measure(PTM)questionnaires were used to assess autistic traits and prosocial behaviors. 49 participants were drawn from the total sample for the next procedure. The Chinese Version of Inter?personal Reactivity Index(IRI-C)and Reading the Mind in the Eyes Test(RMET)were used to assess empathy and theory of mind.[Results]The AQ-C's total(14.8±5.3 vs 13.8±5.3,P=0.031)and Socialness subscale(29.8±6.1 vs 27.6±6.0,P=0.001)scores in the low PTM group were higher than those in high PTM group. The IRI-C's total(46.5±9.9 vs 52.8±8.6,P=0.025)and Perspective Taking subscale(10.3±3.6 vs 12.1±2.4,P=0.049)scores in the low level of prosocial behavior group were lower than those in high lev?el group. Scores of RMET showed no significant difference between the two groups.[Conclusions]Individuals with lower level of pro?social behaviors has higher AT,which may be related to deficits of cognitive empathy. No association between ToM and prosocial be?haviors has been found.
