A substance-related word-association test (WAT) is one of the commonly used indirect tests of substance-related implicit associative memory and has been shown to predict substance use. This study applied an item response theory (IRT) modeling approach to evaluate psychometric properties of the alcohol- and marijuana-related WATs and their items among 775 ethnically diverse at-risk adolescents. After examining the IRT assumptions, item fit, and differential item functioning (DIF) across gender and age groups, the original 18 WAT items were reduced to 14 and 15 items in the alcohol- and marijuana-related WAT, respectively. Thereafter, unidimensional one- and two-parameter logistic models (1PL and 2PL models) were fitted to the revised WAT items. The results demonstrated that both alcohol- and marijuana-related WATs have good psychometric properties. These results were discussed in light of the framework of a unified concept of construct validity (Messick, 1975, 1989, 1995).

Prior studies suggest that lower levels of mindfulness contribute to the motivation of using alcohol to cope with distress. Research examining this possibility is scarce or limited to alcohol, but not marijuana, related outcomes. We examined separate models (for alcohol and for marijuana) to determine the associations between trait mindfulness (describing, acting with awareness, non-judging, non-reactivity) and alcohol and marijuana outcomes (use indicators and negative consequences) via emotional psychopathology (i.

Background: Evidence suggests that adults with a history of child maltreatment (CM) engage in substance misuse driven by 'coping motives': maladaptive beliefs that substances help them cope with negative emotions. However, the specificity of this risk pathway is under-researched in younger and non-Western cohorts.
Objective: The present study aimed to determine whether coping motives play a distinct role compared to other motives for substance use in mediating the relationship between CM and problematic alcohol and marijuana use in a sample of South African adolescents.

Background: Simultaneous alcohol and marijuana (SAM) use has been associated with greater alcohol use and consequences at the daily level, but limited research has examined SAM use in relation to marijuana use and its consequences. This study tested daily associations between SAM use and four outcomes: alcohol use (number of drinks), marijuana use (hours high), negative alcohol consequences, and negative marijuana consequences.
Methods: A community sample of young adults [ages 18-25, mean (SD) = 21.

Social media posts represent a major route by which youth share their substance use cognitions and experiences with others. Extant research has primarily examined relations between alcohol-related posts and posters' own alcohol use, yet little is known about the role of social media in the use of less socially accepted substances, namely tobacco and marijuana. Our study represents the first to examine the relative strength of this relation across alcohol, tobacco, and marijuana.

Background: The prevention of youth marijuana use has become a national priority in the United States. This study examined the influence of parent and peer disapproval on youth marijuana use, mediated by youth risk perception. Because the legal status of marijuana use can influence individual perceptions of the drug, this study investigated differences in the mediating mechanism between youth living in states with medical marijuana legalization (MML) and those living in non-MML states.
