Abstract
The purpose of this study was to gain a better understanding of the association between youth substance use patterns and mental health symptoms, and the risk and protective factors unique and common to each of these areas. A survey was administered to a random sample of 663 youth ages 12 to 18 in Victoria, British Columbia. As expected, age was a strong predictor of greater frequency and amounts of alcohol consumption. Males were at higher risk for alcohol consumption and externalizing problems while females were more susceptible to internalizing problems. Youth who scored lower on substance use and reported fewer mental health symptoms rated their parents and peers as being more protective. Youth who scored higher on substance use scored higher on the risky peer affiliations scale.
