Under the social background of increasingly fierce competition and increasing pressure,psychological problems show the trend of "younger age",and the mental health problems of adolescents can’t be underestimated.As one of the important problems of adolescent psychological development,self-identity has a profound influence on adolescent growth and development in the future.Self-identity is formed under the interaction of various factors.If we can dig out the positive factors,it can help adolescents to establish a good sense of self-identity.Therefore,from internal and external factors,this thesis analyzes the factors affecting teenagers’ self-identity.Using the data of China family tracking survey(CFPS)in 2018,this thesis uses a variety of statistical analysis methods to study adolescents’ self-identity and influencing factors.Firstly,descriptive statistics and cross analysis were used to analyze the status quo of adolescents’ selfidentity and the relationship between different individual characteristics and adolescents’ selfidentity,and association rules were used to explore the association rules of adolescents’ bad behaviors.Secondly,the relationship model between adolescent self-identity and family objective environment,family subjective atmosphere,school environment perception and mental health was constructed,and the structural equation model was used to analyze the influence of each factor on adolescent self-identity.Finally,using the multi-group structural equation model,this thesis explores the individual characteristics of the influencing factors of adolescents’ self-identity from the perspective of urban-rural differences and gender differences.According to descriptive statistics,adolescents have the highest interpersonal identity;through cross analysis,it is found that the academic identity of rural adolescents is seriously polarized,and the ability identity of female adolescents is higher than that of male adolescents;the results of association rules show that there is aggregation of teenagers’ bad behavior;the results of structural equation model show that family objective environment,family subjective atmosphere,school environment perception and mental health can significantly and positively affect adolescents’ self-identity,among which the most influential factor is school environment perception;the results of multi group structural equation model show that there are urban-rural differences in the impact of family objective environment on self-identity,and there are no gender differences in the impact of various factors on adolescents’ self-identity.Finally,some suggestions are put forward according to the analysis conclusions. |
