Objectives:
To examine variable frequencies and relationships between students' intentions and confidence with their intervention.
Methods:
Incoming freshmen (509 of 1155 students responded) completed a survey 2 months into college.
Results:
Most (75.2%) students intervened into others' drinking, usually as a caretaker. Students reported more intention to intervene with others with whom they had more affiliation, and confidence with less intrusive intervention. Intention to intervene (b=0.36, SE=0.10, P<0.001) and intervention confidence (b=0.27, SE=0.06, P<0.001) correlated with intervention.
Conclusions:
With education to enhance their intention and confidence to intervene, first-year college students might be encouraged to intervene into others' social drinking.
