Objective To discuss the difference of handwriting characteristics of schizophrenia,neurosis and healthy people according to the gender,the age and the level of educated.Methods The handwriting data were obtained under the standard condition of handwriting,then the 24 Chinese characters handwriting image information were transformed into digital data using the quantitative characteristics of Chinese characters handwriting recognition system (CCQAS4.0),finally the data of 99 patients with schizophrenia and 131 patients with neurosis were analyzed.Results Many significant differences had been found in schizophrenia,neurosis and norm group (P ＜0.05,P＜0.01),such as footer space((198.33±26.50) mm,(180.31±39.31)mm,(192.39±35.08) mm),average line spacing ((4.02 ± 1.68) mm,(5.34 ± 2.20) mm,(4.76 ± 2.00) mm) etc ; and there were also some important differences between the schizophrenia patient and the neurosis patient from different gender,age and education level in the 24 handwriting characteristics (P＜0.05,P＜0.01).Conclusions (1) Significant handwriting characteristic differences have surely been found among the schizophrenia/neurosis patient and normal people.(2) Gender,age and education level have impact on the characteristic in the schizophrenia patient and the neurosis patient.
