Cognitive-affective stress response: effects of individual stress propensity on physiological and psychological indicators of strain.
The purpose of this study was to define further the role of individual stress propensity in physiological arousal and subsequent subjective stress and strain by measuring stress-induced reactivity in a laboratory setting. Individual predisposition to stress is conceptualized as a latent construct, cognitive-affective stress propensity, that is manifested as multiple trait indicators, e.g., negative affectivity, anger-irritability, and negative self-esteem. For 80 undergraduates experimental treatments were two stressors, time pressure and performance feedback. Physiological arousal indices included skin temperature, blood volume, and electromyographic activity. Results provide some support for the hypotheses that this propensity moderates the relationships between stressor and physiological arousal and between physiological arousal and subjective stress and strain.
