| Social adaptation is an important index to measure the social development of primary school students,and it is also the adaptability and behavior of primary school students in the process of socialization.At present,domestic studies on social adaptation mostly focus on the social adaptation of primary and middle school students at the enrollment stage.The social adjustment of upper primary school students is at a turning point,but there are very few related studies.Therefore,it is very important to understand the current situation of social adaptation of primary school students and senior students in our country,and to explore its influencing factors.Social adaptation is influenced by multiple factors,such as family factors and an individual’s cognitive abilities.With the acceleration of the urbanization process,more and more grandparents are involved in the raising of grandchildren,and a new type of relationship has emerged in the families of primary school students in our country-the joint parenting relationship of grandparents.As a family factor,the co-parenting relationship between grandparents has an important impact on the social adaptation of primary school students.And this effect may also be realized through individual factors.Previous studies have shown that parental nurturing relationship has an impact on sibling relationship and social adoption.Therefore,this study starts from the social point of view in the family system of co-parenting relationship between grandparents,sibling relationship and individual cognition,understands the current situation of the development of social adaptation of senior primary school students,and explores the impact of co-parenting relationship of grandparents on the social adaptation of senior primary school students.,and on this basis,explore the mechanism of sibling relationship and social perspective taking.Social adaptation is influenced by a variety of factors,such as family factors and an individual’s cognitive abilities.With the acceleration of urbanization,more and more grandparents are involved in the upbringing of grandchildren,and a new type of relationship has emerged in the families of primary school students in our country-the relationship of co-parenting of grandparents.As a family factor,the co-parenting relationship of grandparents has an important impact on the social adjustment of primary school students.This influence may also be achieved through sibling relationships and social point of view.Therefore,this study starts from the social perspective selection in the co-parenting relationship,sibling relationship and individual cognition of grandparents in the family system,understands the development status of social adaptation of upper primary school students,explores the influence of grandparents’ co-parenting relationship on the social adaptation of upper primary school students,and discusses the mechanism of sibling relationship and social perspective selection on this basis.This study was divided into two parts,the first study used the social opinion selection questionnaire of middle school students to conduct a questionnaire survey of 520 primary school students in Tangshan City,and 499 valid questionnaires were recovered,with an effective recovery rate of 96%.Since the previous sample of the questionnaire only included middle school students,in order to verify whether the questionnaire was suitable for elementary school students,some of the questions were deleted,and the revised questionnaire included three factors,namely emotional understanding,stance interpretation,and opinion cognition.The revised questionnaire has good reliability and validity.In Study 2,the Social Opinion Selection Questionnaire of Primary School Students in Study 1 was used to measure the social opinion selection ability of upper primary school students.The Grandparents’ Co-parenting Relationship Scale,the Chinese Sibling Relationship Questionnaire and the Children’s Social Adaptation Questionnaire were used to measure the co-parenting relationship,sibling relationship and social adaptation of upper primary school students.This paper aims to understand the current situation of social adaptation development of upper primary school students,and explore the influence of grandparents’ co-parenting relationship on social adaptation,as well as the mechanism of sibling relationship and social perspective choice.The following conclusions are drawn:(1)There are significant differences in the social adaptation of senior primary school students in terms of gender,grade and student status.(2)There are significant correlations among grandparents’ co-parenting relationship,sibling relationship,social perspective taking and social adaptation.(3)The grandparent co-parenting relationship can positively predict social adaptation(4)The sibling intimacy dimension in the sibling relationship has a partial mediating effect on the impact of the grandparent co-parenting relationship on social adaptation.(5)The emotional understanding dimension and standpoint interpretation dimension in social perspective taking have partial and complete mediating effects on the impact of grandparents’ co-parenting relationship on social adaptation,respectively.(6)The dimension of sibling intimacy in sibling relationship and the dimension of emotional understanding in social perspective taking have a chain mediating effect on the impact of grandparent co-parenting relationship on social adaptation;the dimension of sibling intimacy in sibling relationship and the dimension of social perspective taking The dimension of stance interpretation plays a chain mediating role in the impact of grandparents’ co-parenting relationship on social adaptation. |
