Research On The Application Of The Draw-a-person Test In Pupils’ Aggression Assessment

In recent years,as school violence becomes more and more prevalent among younger children,aggression,a lifelong personality trait that emerges early in an individual’s life,has received widespread attention from all sectors of society.This,also has been given high priority as a major internal cause of school violence.As pupils are at the beginning of various psychological problems,studies have shown that childhood aggression not only has a negative impact on current physical and mental health,but also increases the risk of violent crime in adulthood.In view of this,it is an urgent task for researchers to develop an instrument that can identify childhood aggression reasonably early and yet not be limited by the child’s literacy level.In contrast,the Draw-A-Person test has been widely used by national and international researchers in the assessment of depression and anxiety in children,as it allows subjects to make realistic responses in an unconscious state and is not limited by words.However,there is basically no research in the field of aggression,especially in pupils.Therefore,to explore the validity and application value of the Draw-A-Person test in the assessment of aggression in pupils,the study had been conducted in the following four parts.Study I is a status survey study.A total of 1300 pupils in Shandong,Hainan,Xinjiang,Shaanxi,and Hubei provinces were used as the subjects and the Buss-Perry Aggression Scale was used as the instrument.The results showed that the overall detection rate of aggression among pupils was 49.80%,and the total mean score was2.51,which is in the middle to upper range.Study II was an exploratory study.Based on the scores of the Study I scale,the Draw-A-Person test was administered to subjects whose scores were located in the high and low 27%,and a chi-square test and logistic regression analysis were used to screen for indicators that effectively predicted aggression.The results showed that 12 indicators,such as P1 and P2,were more likely to show up in the results of the Draw-A-Person in the high-aggression group.Study III was a validation study.Fifty children with clinically diagnosed aggressive personality disorder were used as the aggression group and 100 normal pupils were used as the control group to administer the Draw-A-Person test,and t-tests were used to verify the differences between the mean values of the items screened in Study Ⅱ in the two groups;the predictive validity of each indicator was verified by using the recall and precision statistical methods.The results showed that,there were group differences in 11 indicators such as P1 and P2,and the average precision of each indicator was 74.72%.Study IV was an assessment system construction and typical case application study.A convenience sampling method was used to reselect 500 pupils to administer the Draw-A-Person test and the Aggression Scale,then factor and norm determinations were made for the indicators identified in Study Ⅲ using factor analysis as well as other methods.Next,three cases were selected to test the clinical applicability of the system.The results showed that the 11 indicators could be divided into 4 factors,the Intra-rater reliability of the evaluation system was 0.78,the Cronbach α was 0.71,the split-half reliability was 0.59,the total score threshold was 2,the threshold of each factor was 1.Based on,the following conclusions were drawn.First,the high rate of aggression detection in pupils needs to be taken into account in mental health education efforts.Second,some drawing indicators of the Draw-A-Person test can predict the aggression of pupils,and the accuracy is very high.Therefore,it is feasible to use the Draw-A-Person test as an effective supplement and auxiliary tool for assessing aggression in pupils.In the future,we should continue to increase the sample size to improve the scoring criteria of the Draw-A-Person test,so as to provide a statistical foundation for its application as a scientific and accessible tool for screening aggression and other psychological problems of pupils on a large scale.
