The purpose of this study was to develop a new measure of incidental behaviors that put college students at increased risk of legal consequences while using alcohol, the Legal Risk Behaviors while using Alcohol (LRBA) scale. Two hundred and twenty one college students who used alcohol were recruited to complete an online study about their use of alcohol, specific behaviors engaged in while using alcohol, and associated consequences. Analyses revealed that the 19-item LRBA consisted of three factors--"Risky Behaviors," "Protective Behaviors," and "Private Settings." Analyses suggested that the LRBA had adequate test-retest reliability and internal consistency. Initial results indicate that the LRBA may be a useful measure to help us better understand what behaviors college student engage in that increase their risk for experiencing a legal encounter.
