Implicit theories of emotion and mental health during adolescence: the mediating role of emotion regulation.

Despite strong evidence of the influence of implicit theories of emotion (ITE) on mental health symptoms among adult samples, scant attention has been paid to this important relation during adolescence. Moreover, it remains unclear which proximal processes may help to explain the link between ITE and mental health. As such, the current study had two objectives: (1) to assess the association of ITE and later anxiety and depressive symptoms within an adolescent sample, and (2) evaluate the mediating role of real-world emotion regulation strategies on the association between ITE and mental health. A sample of 13-15-year-old adolescents (n = 183, mean age = 13.9, SD = 0.91, 50% female) completed a measure of ITE (Time 1), and subsequently reported on their emotion regulation strategy use via an ESM smart-phone app for two weeks (Time 2). Youth then reported on their anxiety and depressive symptoms six months later (Time 3). Mediational analyses revealed that the proportion to which adolescents used reappraisal and suppression mediated the association between ITE and depressive symptoms: higher levels of incremental theories of emotion were associated with more reappraisal, and less suppression, use, which in turn predicted fewer depressive symptoms six months later. None of the strategies measured, however, mediated the association between ITE and anxiety symptoms.
