Scenario descriptor and laboratory studies evaluated a decision-theoretic m
odel of stress arousal and coping propensity composed of 2 stress expectanc
ies; namely, expected stress given engagement in coping activity and expect
ed stress given nonengagement in coping activity. The model predicted (a) t
hat coping propensity would vary inversely with the ratio of the first stre
ss expectancy to the second and (b) that stress arousal would vary with the
lesser of the 2 stress expectancies. It was also predicted that the smalle
st stress expectancy would dictate coping activity and that the proximity o
f the stress expectancies would engender stressing response conflict. Resul
ts supported the first hypothesis when differences in ratio values were sal
ient. The second hypothesis also was supported, but in the scenario descrip
tor study only. Proximity of stress expectancies as sources of stress arous
al received little or no support.
