The mediating effect of adaptive and maladaptive emotion regulation strategies on executive functioning impairment and depressive symptoms among adolescents.

Past research results suggest that executive functioning (EF) impairment represents an important vulnerability factor in depression. Little research, however, has examined mechanisms underlying this association. The current study investigates the associations between EF impairment, emotion regulation (ER) strategies, and depressive symptoms in a sample of 579 adolescents (320 females, mean age = 12.06 years). Parents reported on adolescents' EF and general psychopathology, and adolescents self-reported ER strategies and depressive symptoms. The results indicate that greater EF impairment is associated with more depressive symptoms. Youth with greater EF impairment reported more maladaptive ER and less adaptive ER, and maladaptive and adaptive ER strategies jointly mediated the association between EF impairment and depressive symptoms. The results highlight an important role of both maladaptive and adaptive ER in explaining the relationship between EF and depressive symptoms and suggest that clinical interventions targeting ER skills may provide one strategy for the prevention and treatment of depression. Further longitudinal research is needed to replicate these results and evaluate the causality of the relations.
