“…Drawing on theories of stress diathesis and theories of control and defense mechanisms (Mirowsky and Ross, 1990), they have shown that uncertainty stress and certainty stress like life stress or study stress, although related, are distinct components of stress (Wu et al, 2016(Wu et al, , 2018Yang et al, 2017bYang et al, , 2018Peng et al, 2019). Yang et al (2017a) found that the prevalence of severe uncertainty stress among Chinese college students was 19.6%, while severe life stress prevalence was 8.6%. Some studies have provided empirical evidence that uncertainty stress, in particular, was associated with a range of negative health outcomes, including self-reported short-and long-term illness, alcohol abuse, unintentional injuries, deliberate self-harm, and suicidal ideation among Chinese college students (Wu et al, 2016(Wu et al, , 2018Yang et al, 2017bYang et al, , 2018Peng et al, 2019).…”
