Substance use in incarcerated male offenders: Predictive validity of a personality typology of substance misusers

Survival analysis indicated a significant effect of levels of sensation seeking, a trend of cluster membership, and anxiety sensitivity on days until first institutional substance use. Conclusion: High levels of sensation seeking and low anxiety sensitivity appear to indicate increased risk for substance misuse in this population.
