The present study also suggests that it may still be a valuable goal for interventionists to improve readiness to change, as well as to reduce other drug use. In particular, greater readiness to change, being a non first-year student, and no other drug use at baseline predicted a better intervention outcome when baseline HED and AP levels were statistically controlled but not when other individual and situational factors were also examined simultaneously. Although this indicates that there were no unique effects of these variables above and beyond other co-existing individual and situational factors, targeting these co-existing factors might improve intervention outcomes. Whereas experiencing a serious incident, and certainly being a first year student, cannot be subject to change by interventions, early preventive interventions with incoming students might help them reduce problematic behaviors that may lead to serious incidents.
