Socio-affective influences on adolescent mental health problems
type: CreativeWork
description: Adolescence is a period of vulnerability for the development of mental health disorders, particularly emotional disorders. In order to reduce this vulnerability, the identification of malleable targets for prevention and early intervention is essential. This thesis therefore explored socio-affective influences on adolescent emotional disorders, with a particular focus on adolescent mental health during the COVID-19 pandemic. Drawing on the empirical evidence, this thesis also describes the development of a novel gamified intervention for adolescents. Chapter 1 presents a broad overview of the adolescent cognitive, affective and social development literature, and provides an empirical justification for investigating socio-affective influences on adolescent emotional disorders. In Chapter 2, the role of social rejection sensitivity, a proposed risk factor for emotional disorders, in mental health across the lifespan during the COVID-19 pandemic was examined. Results showed that younger people were susceptible to increased mental health problems during the pandemic. Notably, sensitivity to social rejection moderated the relationship between age and mental health problems, such that younger individuals with higher social rejection sensitivity demonstrated the most mental health problems after 1 year of the pandemic. In Chapter 3, affective influences on adolescent mental health during the COVID-19 pandemic were examined. Supporting the findings of Chapter 2, younger age was associated with higher levels of negative affect and lower positive affect across the first year of the pandemic. More frequent use of maladaptive emotion regulation strategies partially accounted for variance in the relationship between age and negative affect after 1 year of the pandemic. Chapter 4 examined the role of cognitive and affective control, argued to be the cognitive building blocks of effective emotion regulation, in adolescent mental health. Heightened depressive symptomatology was ass…
