“…In the causal mediation component it is posited that hopelessness mediates between the diathesis-stress component and hopelessness depression symptoms in the etiological chain. Available evidence is inconsistent, with some researchers providing full or partial support for this hypothesis (e.g.. Hong, Gwee, & Karia, 2006) and others showing no support (e.g., Abela, 2001;Stone, Gibb, & Coles, 2010) Although much is known about the diathesis-stress component, only a few studies of the hopelessness theory have been carried out with undergraduate samples in China (e.g., Wang & Zhang, 2006;Xin, Ma, & Geng, 2006). Despite the strengths of these Chinese studies, Gibb and colleagues (2006) found some common limitations.…”
