Correlations between eating behavior, as measured by the Three-Factor Eating Questionnaire (TFEQ) and personality traits of impulsivity and compulsivity, as measured by the Barratt Impulsiveness Scale (BIS-11) and the Obsessive–Compulsive Inventory (OCI-R). (a and b) impulsive personality traits are significantly associated with uncontrolled eating in healthy men, but not in cocaine-dependent men. (c and d) compulsive personality traits are associated with deliberate restriction of food intake to influence body weight in cocaine-dependent men but this relationship is not seen in healthy men.
