Policies vary substantially in terms of providing sources of psychosocial enrichment. Behavioral economic models of substance use and addiction emphasize that deficits in access to substance-free sources of reward increase substance reinforcing value and risk for addiction. The current study used an alcohol demand curve approach to test the hypothesis that various indices of reward deprivation would be associated with elevated alcohol reinforcing efficacy.

Objective: Cannabis use is increasing among college students and commonly co-occurs with anxiety symptoms in this age group. Interventions that reduce anxiety may also reduce cannabis use. Behavioral economic theory suggests that substance use reductions are most likely when there is an increase in substance-free reinforcement.

With the spectacular rise of US overdose deaths, bereavement for these affected families has become a matter of increasing concern. Qualitative research has highlighted the role of stigmatization as well as guilt and shame among this population. However, the magnitude and pre-death predictors of stigmatization, guilt, and shame have yet to be assessed quantitatively.

Background: The association between behavioral economic demand and various alcohol use outcomes is well established. However, few studies have examined whether changes in demand occur following a brief alcohol intervention (BAI), and whether this change predicts alcohol outcomes over the long term.

Methods: Parallel process piecewise latent growth curve models were examined in a sample of 393 heavy drinking emerging adults (60.

Objective: The Young Adult Alcohol Consequences Questionnaire (YAACQ) was designed to measure the various domains of alcohol-related problems experienced by emerging adults (EAs), but has primarily been used in college samples and it remains unclear whether the psychometric properties of the YAACQ function similarly in racially and economically diverse populations. The present study assessed the factor structure and evaluated measurement invariance, latent mean differences, and correlates of the 48-item eight-factor YAACQ across college status, race, and childhood socioeconomic status (SES).

Method: EAs ages 21.

Background: Behavioral economic theory predicts that low access to environmental reward is a risk factor for alcohol use disorder (AUD). The Substance-Free Activity Session (SFAS) is a behavioral economic supplement to standard brief alcohol interventions that attempts to increase environmental reward and may therefore have beneficial effects, particularly for individuals with low levels of environmental reward.

Methods: Participants were 393 college students who reported at least 2 heavy-drinking episodes in the past month.

Objective: Diminished access to environmental rewards is an established risk factor for addiction and a focus of many effective treatment approaches. Nevertheless, there is inconsistency in measurement approaches and a need for a psychometrically sound measure. The Reward Probability Index (RPI; Carvalho, , 2011, pp.

High levels of 3 behavioral economic indices (delay discounting, alcohol demand, and proportionate substance-related reinforcement) are consistently associated with greater alcohol misuse and alcohol-related problems. However, it is unclear whether and how these variables jointly increase the risk for alcohol-related outcomes among college students who engage in heavy episodic drinking (HED; 4/5+ drinks for women/men, respectively). The current study used a person-centered approach to identify similar patterns of behavioral economic domains among heavy-drinking college students and investigate the relationship between these empirically derived classes and alcohol-related outcomes.
