The Effect of the School Environment on the Emotional Health of Adolescents: A Systematic Review

Pediatrics, 05/16/2012

Kidger J et al. – There is limited evidence that the school environment has a major influence on adolescent mental health, although student perceptions of teacher support and school connectedness are associated with better emotional health. More studies measuring school–level factors are needed. Randomized controlled trials evaluating 1 or 2 environmental components may have more success in establishing effective and feasible interventions compared with complex whole–school programs.


  • Searches of Medline, Embase, PsychINFO, CINAHL, ERIC, the Social Citation Index, and the gray literature were conducted.
  • Criteria for inclusion were (1) cohort or controlled trial designs, (2) participants aged 11 to 18 years, (3) emotional health outcomes, and (4) school environment exposure or intervention.
  • Relevant studies were retrieved and data extracted by 2 independent reviewers.


  • Nine papers reporting 5 controlled trials were reviewed, along with 30 cohort papers reporting 23 studies.
  • Two nonrandomized trials found some evidence that a supportive school environment improved student emotional health, but 3 randomized controlled trials did not.
  • Six (20%) cohort papers examined school-level factors but found no effect.
  • There was some evidence that individual perceptions of school connectedness and teacher support predict future emotional health.
  • Multilevel studies showed school effects were smaller than individual-level effects. Methodological shortcomings were common.
