    Psychopathic Traits, Affect, and Cocaine Use-Related Outcomes
    (2014) Long, Katherine; Lejuez, Carl W; Psychology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    Substance abuse and associated public health and economic consequences represent a pervasive and costly problem. Among inner-city substance users, crack/cocaine is the most common drug of choice and is associated with health compromising behaviors. Substance Use Disorders (SUDs) are more prevalent, severe, and difficult to treat among individuals with Antisocial Personality Disorder (ASPD). Psychopathy is a construct which is related to but distinct from ASPD, and the relation between primary psychopathic traits and substance use is not well understood. The present laboratory experimental study of cocaine use-related outcomes in the context of mood inductions among cocaine users found that primary psychopathic traits were negatively associated with attentional bias for cocaine-related cues but not associated with self-reported craving. Assignment to the negative affect manipulation was related to greater attentional bias but not to craving. The interaction between mood condition and primary psychopathic traits was not a significant predictor of either outcome.

    Toward a Better Understanding of the Relationship Between Gender and Crack/Cocaine Use and Dependence
    (2008-08-27) Reynolds, Elizabeth Keats; Lejuez, Carl W.; Psychology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    Building on previous research, this cross-sectional, exploratory study of 142 crack/cocaine users, currently enrolled in residential substnace abuse treatment, aimed to replicate previous findings indicating that females evidence greater use (past year and heaviest use) and dependence (current and lifetime) of crack/cocaine compared to males. In addition, this study sought to examine potential risk factors in the relationship between gender and crack/cocaine drug use. Results indicated that females used crack/cocaine significantly more frequently in the past year. Males and females did not differ on dependence or lifetime heaviest use. Frequency of use by romantic partner and lifetime major depressive disorder diagnosis were significantly related to both gender and past year crack/cocaine use frequency, and met criteria as risk factors in this relationship. This study adds to previous reports of greater crack/cocaine use among inner-city females and identified potential factors underlying this greater frequency of use by women.
