|It is widely held in socio-behavioral studies of suicide that higher levels of stress and lower
levels of economic status amplify suicidal vulnerability when confronted with a proximal
stressor, reflecting the traditionally prevalent understanding in health psychology and sociology
that associates adverse life circumstances with undesirable mental health outcomes.
However, upon reflection, there are strong theoretical reasons to doubt that having more
stress or being in a more stressful environment always increases suicidal vulnerability given
the occurrence of a crisis. Using large nationally representative public survey data on South
Korean adolescents, I show that the association between recent psychosocial crisis and suicidal
ideation often gets stronger with more favorable levels of perceived stress and improving
levels of family economic status. Overall, the increase in the probability of suicidal
ideation from recent exposure to a psychosocial crisis is consistently the smallest around
medium levels of stress or family economic status and larger at low or high levels. A supplementary
exercise suggests that the identified moderation effects operate mainly in virtue of
individual-level stress or family economic status in the relative absence of contextual influences
at the school level. The findings present preliminary evidence of the stress inoculation
hypothesis with regard to suicidal ideation. Research on suicidal vulnerability could benefit
from increased attentiveness to the mechanisms through which being in an adverse or unfavorable
life situation could protect against the suicide-inducing effects of proximal stressors.
