The relationship of NEO-PI performance to coping styles, patterns of use, and triggers for use among substance abusers.
We investigated the construct validity of the NEO Personality Inventory (NEO-PI) with a clinical population of 2,676 substance abusers. Scores on the NEO-PI were correlated with self-reported measures of psychopathology as well as patterns of substance abuse, reported coping styles, relapse triggers, and relapse confidence. Substance abusers were more Neurotic and less Agreeable and Conscientious than were the NEO-PI nonclinical normative sample. Within subgroups of substance users, cocaine-only users were more Extroverted and Open than were alcohol-only users. Polysubstance users were the least Agreeable and Conscientious group. Alcohol-only users and polysubstance users scored higher on Neuroticism than did other groups. Personality dimensions related to reported coping styles in meaningful ways. For example, Neuroticism was highly related to escape avoidant coping (r = .53), Agreeableness was negatively related to confrontive coping (r = -.28), and Conscientiousness was related to problem solving (r = -.27) and negatively related to escape avoidance (r = -.29). Neuroticism, Conscientiousness, Agreeableness, and Extroversion were associated with reported triggers of use including negative emotional states, social rejection, and tension. Higher levels of Conscientiousness, Agreeableness, and Extroversion were associated with greater confidence in ability to refrain from use, whereas Neuroticism was associated with a corresponding lack of confidence in self-restraint.
