This study investigated the predictability of rational decisionmaking
style on career decision-making status and treatment gains based on a
computer-based career intervention. Decision-making style, in relation
to pretreatment career status as well as its efficacy in predicting i
ntervention outcomes, was also examined. Seventy-four undecided univer
sity students participated in the study. Results show that employing d
ecision-making strategies based on an individual's preference signific
antly increased students' career decidedness and decreased career inde
cision, choice anxiety, and reason complexity. Rational decision-makin
g style is positively associated with career decidedness and negativel
y associated with the exploration stage of decision making; it is not,
however, predictive of treatment gains.
