| Background The diagnosis of schizophrenia is mainly through psychiatric examination and objective scale,lack of objective and quantitative diagnostic tools,and schizophrenia in a typical prodromal period before symptoms are not easy to cause the family's attention,but the early diagnosis and early treatment of schizophrenia has a great influence on prognosis of schizophrenia.The tree-drawing test is one of the subjective tests,in 1952,founded by Koch,a Swiss psychologist.Under the condition of limiting the theme,they draw the tree-drawing,and their personality and sub-consciousness were analyzed by the tree-drawing.The existing domestic and foreign research shows that trees draw test has better reliability and validity of tree-drawing,recent studies abroad about focus on the study of disease treatment.The domestic scholars on the one hand applied tree-drawing test to different people,to widen the scope of application of tree-drawing test,the other hand applied tree-drawing test to neurosis,depression,anxiety,schizophrenia,to study the differences in special groups and normal control groups in the index compared to the discovery and these disease index,establish the diagnosis manual with high correlation.The study by surveying tree-drawing test in schizophrenia and normal control group,compared two groups of trees to draw quantitative indicators,to explore the possibility of tree-drawing test as a schizophrenia diagnosis,and provide a new direction for exploration for clinical diagnosis of psychiatric and drawing test research.Objective Through the extraction and quantitative analysis of the projection index of the tree-drawing painted by schizophrenic patients,to explore the characteristic indexes of patients with schizophrenia in the tree-drawing test and provide the basis for the diagnosis of schizophrenia.It is the first time that computer automation has been introduced into the research of drawing projective test.It provides a new research direction for the follow-up research of drawing projection test,and also provides an explore view for the clinical diagnosis of mental disorders.Methods In this study,used the tree-drawing test,founded by Koch,a Swisspsychologist,among 69 schizophrenic patients and 59 patients without psychotic symptoms in healthy subjects measured tree-drawing test and using computer image recognition and data acquisition,quantitative research on tree-drawing test.The results were measured by normality test,then analyzed by two sample independent-ttest.Results There were 6 tree-drawing test quantitative indexes had statistical significance between schizophrenia patients and healthy subjects were: crown height,crown width,trunk width,crown area,trunk area the total area,7 quantitative indexes no statistically significant,the total height of trees,trunk height,root height,root width,root area,trunk and crown height ratio,trunk crown width ratio.Conclusion The research introduces the research progress of tree painting projection test in recent years,summarizes the theoretical basis of tree-drawing protective test,found that schizophrenia patients and normal people in the tree-drawing test,there is statistical significance of crown,trunk,tree size differences.Because of the limited time and restrictions on the conditions of study during school,this paper only envisaged the initial whole research system,namely the development of scanned image data acquisition software,comparison between schizophrenia group and normal control group differences of quantitative indicators,the preliminary data for the follow-up study.The Future research requires more human and human resources,and it is hoped that further research can help the clinical assistant diagnosis of schizophrenia... |
