Studies have documented close relationship between parenting behaviour (e.g., harsh parenting, abuse, and neglect) and depression (Cole et al., 2016). It is however not entirely clear what’s the mechanism underlying such association. How individual process rewards has been found to be closely associated with depression (Beck, 1967; Disner et al., 2011),and can potentially be a mediator exaplaining the link between parenting and depression. Specifically, research has shown that an individual suffering from depression differs from people without depression in terms of how they value rewards according to time (Pulcu et al., 2014). In this study, we aim to investigate the mediating effect of reward valuation in the association between parenting in adolescence and depression in early adulthood, a period characterised by heightened risk for depression, as well as time poses parenting challenges. We will also explore the association with financial difficulties, gambling problems, employment status, and romantic relationship quality in early adulthood as a proxy of individual functioning.
