The hardy personality: cognitive and physiological responses to evaluative threat.

Hardy persons are hypothesized to be resistant to stress-induced illness, because of their adaptive cognitive style and a subsequently reduced level of physiological arousal. We assessed the cognitive and physiological responses of high and low hardy male undergraduates to a challenging task under high and low evaluative threat. As predicted, hardy subjects endorsed more positive self-statements than did low hardy subjects in the high threat condition. High hardy subjects also reported fewer negative self-statements overall, but this was attributable to the overlap of measures of hardiness and neuroticism. Hardy subjects displayed marginally lower arousal while waiting for the task to begin, but this finding did not approach significance when neuroticism was controlled. Hardy subjects also had higher levels of systolic blood pressure, perhaps because of their active coping efforts. Results support the hypothesized hardy cognitive style but raise questions about the type and timing of organismic strain linking hardiness and health.
