Researchers have suggested that good-quality school climates foster a sense of connection to the school and in this way contribute to fewer emotional and behavioral problems. However, few studies have directly assessed the role of school connectedness as a mediator of school climate effects. Using path analysis, this brief report examined whether four aspects of student perceived school climate (cohesion, friction, competition among students, and overall satisfaction with classes) were indirectly associated with subsequent early adolescent conduct problems and depressive symptoms through school connectedness. Participants were four hundred and eighty-nine 10- to 14-year old middle school students involved in two waves of a study. The results showed that school connectedness mediated the relations between perceived cohesion, perceived friction, and overall satisfaction with classes and subsequent student conduct problems 1 year later. School connectedness was not, however, predictive of subsequent depressive symptoms and thus did not mediate the school climate effects on early adolescent emotional problems.
