School experiences in relation to emotional and conduct problems in adolescence: A 3-year follow up study

Abstract

Background: Mental health in adolescents has become a major public health issue. This study examined school experiences in relation to mental health (emotional problems and conduct problems) from early to middle adolescence. Methods: This longitudinal 3-year follow up study used data from the Swedish Study of Health in School Children in Umeå. Analyses were conducted in 1379 participants that were attending grade six in 2003 or 2006 (age 12 years). KIDSCREEN-52 was used to assess school experiences and the Strengths and Difficulties Questionnaire for emotional and conduct problems. Statistical analyses included repeated measures ANOVA and multiple linear regressions. Results: Positive school experiences decreased while emotional and conduct problem scores increased from grades six to nine. Positive school experiences were negatively associated with emotional and conduct problem scores and contributed to the explanation of mental health scores in middle adolescence after controlling for background factors. When baseline mental health problem scores were taken into account the association with early school experiences disappeared (except for conduct problems in boys). However, incorporating concurrent school experiences in the analysis increased the levels of explanation for emotional and conduct problem scores further. Conclusions: The results of this study confirm that school experiences are linked to emotional and conduct problems. That link may be stronger for conduct problems. In addition, the association of school experiences in early adolescence with later mental health may be overridden by concurrent school experiences in middle adolescence.
