GP-diagnosed internalizing and externalizing problems and dropout from secondary school: A cross-sectional study

Abstract

Background Dropout from secondary education is a major concern in many Western countries because it is associated with later adverse consequences at the individual and societal level. Efforts have thus been made to identify precursors for dropout. The aim of the study was to examine the risk for not finishing secondary education by age 20 when mental health problems were diagnosed during general practitioner (GP) consultations. Methods National registries were linked to assess the association between GP-diagnosed internalizing and externalizing problems from the ages of 15-20 years and school dropout in a sample of 63 970 Norwegians, adjusting for health and social background factors. Relative risks (RR) were estimated by Poisson regression. Results Dropout was bivariately related to both internalizing (RR = 2.2 among girls and 1.7 among boys) and externalizing problems (RR = 2.7 for girls and 2.0 for boys), though the associations were somewhat attenuated in the adjusted analyses. After controlling for somatic comorbidity and parent education level, the absolute risk for not fulfilling secondary education by age 20 was 43% among girls and 60% among boys with internalizing problems and approximately 15% points higher with externalizing problems. The highest absolute risk for dropout was found for boys and girls who have both externalizing and internalizing problems. However, with some overlap in the confidence intervals, the added impact of internalizing problems when added to externalizing problems is uncertain. Conclusions Intervention for mental health problems by a GP could benefit adolescent education outcomes and mental well-being.
