Education and psychological distress in adolescence and mid-life: Do private schools make a difference?     

Alice Sullivan  Samantha Parsons  George Ploubidis  Richard D. Wiggins  Francis Green 《British Educational Research Journal》2021,47(3):599-615

This article extends the evidence base on childhood circumstances, education and psychological distress. We examine the link between childhood advantage and disadvantage, the type of school attended during adolescence and psychological distress at ages 16 and 42. The analysis uses a large, population-based birth cohort study, the 1970 British Cohort Study (BCS70) (n = 17,198) using a structural equation modelling (SEM) approach. More advantaged young people were more likely to attend private schools, but we find no evidence for an effect of private schooling on psychological distress for men, and for women there was an association between private schooling and raised psychological distress at age 16. Having a university degree was associated with a modest reduction in psychological distress in mid-life. We establish that maternal psychological distress at age 10 was a risk factor for the offspring’s psychological distress both in adolescence and in mid-life, and adolescent psychological distress predicts psychological distress in mid-life. We conclude that schools which are academically successful do not necessarily provide wider benefits in terms of mental health.  相似文献

Social origins,school type and higher education destinations     

Alice Sullivan  Samantha Parsons  Richard Wiggins  Anthony Heath  Francis Green 《牛津教育评论》2014,40(6):739-763

To what extent and why do social origins matter for access to higher education, including access to elite universities? What is the role of private and selective schooling? This paper uses the 1970 British Cohort Study (BCS70) to analyse the trajectories of a generation currently in early middle age. We find that the influence of social origins, especially parental education, remains when both a wide range of cognitive measures and school attainment are controlled. Attending a private school is powerfully predictive of gaining a university degree, and especially a degree from an elite institution, while grammar schooling does not appear to confer any advantage.  相似文献
