Do cocaine abusers have radically different personalities than non-abusing college students? This was one of the questions researched in Psychological Assessment (June 1995). Zuckerman–Kuhlman’s Personality Questionnaire (ZKPQ) was administered to a sample of 450 cocaine abusers and a sample of 589 college students. The ZKPQ yields scores (measured on a 20-point scale) on each of five dimensions: impulsive–sensation seeking, sociability, neuroticism–anxiety, aggression–hostility, and activity. The results are summarized in the accompanying table. Compare the mean ZKPQ scores of the two groups on each dimension, using a statistical test of hypothesis. Interpret the results at α = .01.
