| Junior middle school stage is a fast developing period of individual's self-consciousness,one of whose important parts is self-acceptance.As for the rural left-behind junior middle schoolstudent,especially those whose parents aren'taround them,it is of great significance for the profound development of personality,if they can treat themselves more objectively and rationally,and accept their own advantages and disadvantages,which can also help them more easily to face conflicts and problems in life and study.Aggressive especially since that implicit aggressionhas been confirmed,more and more researcheshave done on it,and the subject groups also widespread from kindergartens to adults from different social classes.The study focuses on the the relationship between the self-acceptance of left-behind junior middle school students and aggression.This research firstly analyses that if self-acceptance questionnaire(SAQ)and aggression questionnaire(AQ)are suitable for junior middle school student.And then screening the subjects in junior high school student so as to conduct experiment,this research studies the effects caused by high self-acceptance and low self-acceptance on left-behindjunior middle school students' explicit aggression and implicit aggression in setback situation.The experiment takes 2(setback situation:with or without)X2(self-acceptance: high or low)X2(whether left-behind: left-behind or non-left-behind)mixed experimental designs,among which left-behind and self-acceptance are within-subjects design,while setback situation is between-subjects design.The results of the study are as follows:1 ? The test result of more than 600 junior middle school student shows that self-acceptance questionnaire's total score and two factors' alpha coefficients are respectively 0.849,0.821,0.802,showing that the reliability is fine;Using MPLUS to proceed confirmatory factor analysis,it shows that TLI and CFI indexes are respectively 0.79,0.819,and RMSEA is 0.067,less than 0.08,presenting that construct validity is acceptable and the self-acceptance questionnaire is appropriate forjunior middle school student groups.Aggression questionnaire's score and fourfactor's alpha coefficients are respectively 0.846,0.765,0.730,0.812,and 0.783,showing that reliability is good;Using MPLUSto carry out confirmatory factor analysis,it shows that TLI and CFI indexes arerespectively 0.791,0.809,and RMSEA is 0.054,less than 0.08,presenting that construct validity is acceptable and the aggression questionnaire is appropriate forjunior middle school student groups.2?Explicit aggression as the dependent variable,the three independent variables aresetback situation(F = 210.614,P = 0.000),self-acceptance(F = 4.71,P = 0.032),left-behind or not(F = 7.142,P = 0.008),and all the main effects are significant.The interaction between left-behind and setback situation is significant(F = 4.530,P =0.035).By analyzing simple effect on this interaction,it can be found that whether left-behind or not left-behindsetback situation has a significant effect on explicit aggression.In non-setback situation,left-behind haslittle effects on explicit aggression.(F = 3.66,P = 0.058).But in setbacksituation,it's significant(F = 9.47,P =0.002)that left-behind has a role in explicit aggression,and the setback situation has a more significant impact on left-behind junior high school students' explicit aggression than that on the no left-behind junior middle school students.3?Implicit aggression as the dependent variable,the subjects' compatible task and incompatible tasks are significantly different(t = 12.744,P = 0.000,t = 9.378,P =0.000),explaining that the implicit aggression is existing in the experiment,and the main effects of three independent variables setback situation(F = 35.717,P = 0.000),self-acceptance(F = 4.651,P = 0.033),left-behind(F = 15.764,P = 0.000)are all significant;The interaction between self-acceptance and setback situation is significant(F = 4.622,P = 0.034).By analyzing simple effect on this interaction,it can be found that setback situation has a significant influence on both high self-acceptance and low self-acceptance in implicit aggression.In no setback situation,it's not significant(F=0.3,P=0.585)that self-acceptance level has a role in implicit aggression.But in setbacksituation,self-acceptance level has a significant(F=8.76,P=0.04)effect on implicit aggression,and the setback situation has a more significant impact on low self-acceptance'simplicit aggression than that on high self-acceptance's subjects.Theinteraction between left-behind and setback situation is significant(F=4.982,P=0.028).After analyzing simple effect of this interaction,it reveals that whether left-behind or not,it's significant that setback situation has a role in implicit aggression.While in no setback situation,it's not significant(F=3.69,P=0.057)that left-behind has a role in implicit aggression.But in setbacksituation,it's significant(F=21.81,P=0.000)that left-behind has a role in implicit aggression,and the setback situation has a more significant impact on left-behind junior high school students' implicit aggression than that on the no left-behind junior middle school students.4?The correlations between explicit aggression(r = 0.793,p < 0.01)and implicit aggression(r = 0.381,p < 0.01)are bothsignificant,under the setback and non-setback situations,but there is no significant correlationbetween explicit aggression and implicit aggression,whether in setback situation or no setback situation.Using MPLUS to check the independent model between explicitaggression and implicit aggression,fitting parameters are respectively TLI = 1.025,CFI = 1.000,RMSEA is0.000,less than 0.05,showing that explicit aggression and implicit aggression are two independent structures.The conclusions of the research are as follows:1 ? The reliabilities and validities of the self-acceptance questionnaire and aggression questionnaire is according with the requirement of metrology,which is suitable for the testing of junior middle school students' self-acceptance and aggression.2?Whether left-behind or not left-behind,the explicitaggression on the setback situation is higher than that onno setback situation.However,under setback situation,the explicitaggression level of the left-behind junior middle school students is higher than no left-behind junior middle school students.3 ? The research subjects of implicit aggression are existing;whether the self-acceptance of junior middle school has high self-acceptance or low self-acceptance,the implicitaggression on the setback situation is higher than non-setback situation.But on setback situation,the implicitaggression of the high self-acceptance junior middle school students is lower than low self-acceptance juniormiddle school students;while the non-left-behind junior middle school students is lower than the implicitaggression of left-behind junior middle school students.4?There is no correlation between explicit aggression and implicit aggression,whichare two independent psychological structures. |
