Protective Associations of School Connectedness with Risk of Depression in Nova Scotia Adolescents

Objective: To determine whether school connectedness demonstrated an independent protective association with risk of depression in students in grades 10 to 12 attending a high school in a rural community in southwestern Nova Scotia. Methods: Students at a high school in rural Nova Scotia participated in a self-completion survey in May 2009. Students were asked about a wide range of health-related factors to determine their needs for health services and promotion. Examining girls and boys separately, we used logistic regression to examine associations of an established measure of school connectedness with risk of depression as measured by the 12-item Center for Epidemiologic Studies Depression (CES-D) Scale, while including numerous potential confounding variables in our models. Results: The response rate was 95.2% among registered students present in class during the survey. Four hundred eight students (216 girls and 192 boys) completed both the CES-D12 and the School Connectedness Scale. Higher school connectedness was independently protective of risk of depression in girls (OR 0.85; 95% CI 0.78 to 0.93, P < 0.01) and in boys (OR 0.81; 95% CI 0.71 to 0.91, P < 0.01). Conclusions: Among adolescents in rural Nova Scotia, higher school connectedness has protective associations with risk of depression in both girls and boys, independent of a wide range of factors known to be associated with depression in adolescents. School may be a key place for helping adolescents to develop positive mental health.
