Measuring Outcomes of Alcohol, Marijuana, and Cocaine Use Among College Students: A Preliminary Test of the Shortened Inventory of Problems - Alcohol and Drugs (SIP-AD)

College provides a context for experimentation with alcohol and drugs, the consequences of which range from mild to severe. One purpose of this study involved testing the usefulness of the Shortened Inventory of Problems - Alcohol and Drugs (SIP-AD) to assess negative consequences associated with substance use. A random sample of students (n = 421) was drawn from a medium-sized, public university. Subjects reported patterns of use for alcohol, marijuana, and cocaine over both the last 30 days and the past year. Reliability and factor analyses illustrated the internal consistency and validity of the SIP-AD. Multiple linear regression was also used to show how demographic characteristics and substance use behaviors can predict problems associated with using alcohol and/or drugs
