A pilot trial of a brief intervention for cannabis use supplemented with a substance-free activity session or relaxation training.

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. This randomized pilot trial evaluated the efficacy of a brief motivational intervention (BMI) for cannabis supplemented by either a substance-free activity session (SFAS) or a relaxation training (RT) session for reducing cannabis use, problems, craving, and anxiety symptoms. METHOD: One hundred thirty-two college students (Mage = 19.9; 54% female; 67% White, 31% Black) who reported five or more past-month cannabis use days were randomized to: (a) assessment-only (AO); (b) BMI plus SFAS; or (c) BMI plus RT. Participants in the BMI conditions received two individual counselor-administered sessions plus a brief phone booster session. Outcomes were evaluated 1- and 6-months postintervention. RESULTS: Relative to assessment, both BMI + SFAS and BMI + RT were associated with significant reductions in cannabis problems and craving at 1-month follow-up, and significant reductions in anxiety at 6-month follow-up. Relative to AO, BMI + RT was associated with significant reductions in cannabis use at 1-month follow-up. There were no differences between BMI conditions. CONCLUSIONS: This pilot trial was not adequately powered to conclusively evaluate relative efficacy but provides preliminary support for the short-term efficacy of both two-session interventions for reducing anxiety and cannabis-related risk among nontreatment seeking emerging adults.

Predictors of Stigma, Guilt, and Shame among Adults Bereaved by Fatal Overdose.

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. In the current study, we assess the magnitude of stigmatization, guilt, and shame among 115 adults bereaved by overdose by drawing comparisons with 185 adults bereaved by suicide. Results revealed no significant differences regarding overall levels of stigmatization, guilt, and shame between the overdose and suicide bereaved. Among the overdose bereaved, regression models indicated a number of pre-death factors associated with stigmatization, guilt, and shame, such as the frequency of the decedent's drug use, family drug use severity, and interpersonal conflict between the bereaved and the decedent. Implications and future directions for research are discussed.

Change in alcohol demand following a brief intervention predicts change in alcohol use: A latent growth curve analysis.

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 (60.8% women; 85.2% white; Mage  = 18.77). In these models, two linear slopes represented rates of change in alcohol use, heavy drinking episodes, alcohol-related problems, and demand (intensity and highest expenditure across all price points or Omax ) from baseline to 1 month (slope 1) and 1 month to 16 months (slope 2). Mediation analyses were conducted to estimate the effect of a BAI on 16-month alcohol outcomes through slope 1 demand. RESULTS: A two-session BAI predicted significant reductions in all five outcomes from baseline to 1-month follow-up. Although no further reduction was observed from the 1-month to the 16-month follow-up, there was no regression to baseline levels. Slope 1 demand intensity, but not Omax , significantly mediated the association between BAI and both outcomes-heavy drinking episodes (Est. = -0.23, SE = 0.08, p < 0.01) and alcohol-related problems (Est. = -0.15, SE = 0.07, p < 0.05)-at the 16-month follow-up. CONCLUSIONS: Reducing high valuation of alcohol among heavy drinking emerging adults within the first month following BAI is critical for the long-term efficacy of the intervention. A two-session BAI was associated with enduring reductions in alcohol demand, and the change in demand intensity, but not Omax , was associated with sustained reductions in heavy drinking and alcohol-related problems.

Examining bereavement-related needs and outcomes among survivors of sudden loss: A latent profile analysis.

OBJECTIVE: Recognizing important bereavement-related needs among sudden loss survivors (e.g., suicide, overdose)-a population that is burgeoning and at risk for deleterious outcomes-is a critical task as needs may reflect modifiable grief-related variables that can assist with post-loss adjustment. METHODS: Latent profile analysis was used among 347 sudden loss survivors to (a) identify distinct patterns of needs among survivors of sudden loss, (b) assess predictors of such profiles, and (c) investigate differences in profiles in terms of bereavement outcomes. RESULTS: Four classes of bereavement-related needs were identified: a low needs class, a moderate needs-spiritual class, a moderate needs-relational class, and a high needs (HN) class. Clear differences emerged between need classes with the HN class evidencing the greatest level of grief and mental health sequelae. CONCLUSION: Tending to bereavement-related needs is critical, as they indicate the degree of distress and reflect modifiable therapeutic variables.

Measurement invariance of the Young Adult Alcohol Consequences Questionnaire across college status, race, and childhood SES in a diverse community sample.

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 21.5-25 (N = 602; 57.3% female, 47.0% White, 41.5 % Black, 35.4% noncollege EAs) who consumed 3/4 + alcoholic beverages (for women/men) at least twice in the previous month completed measures of alcohol use, alcohol-related consequences and demographics. RESULTS: Confirmatory factor analysis (CFA) supported the 48-item eight-factor structure across the entire sample. However, one item related to academic achievement was predictably endorsed by few noncollege EAs and thus, was dropped. Multiple-group CFA demonstrated measurement invariance of a revised 47-item eight-factor YAACQ across college status, race, and childhood SES. Assessment of latent mean differences revealed that noncollege EAs reported more alcohol-related consequences overall, compared to college students, including greater endorsement of severe problem domains. White EAs reported more total alcohol-related consequences relative to Black EAs, and EAs of low childhood SES reported more total alcohol-related consequences compared to those of high childhood SES. Furthermore, all eight alcohol consequence factors demonstrated concurrent associations with weekly alcohol use, binge drinking, and high intensity drinking within each subgroup. CONCLUSIONS: Findings suggest that the YAACQ is a psychometrically robust measure of alcohol-related consequences across demographic groups.

Trajectories of reward availability moderate the impact of brief alcohol interventions on alcohol severity in heavy-drinking young adults.

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. Participants were randomly assigned to 1 of 3 conditions following a baseline assessment: a standard alcohol-focused brief motivational intervention plus relaxation training session (BMI + RT), BMI plus Substance-Free Activity Session (BMI + SFAS), or an assessment-only control condition (AO). In a secondary analysis of the data from this study, we used person-centered statistical techniques to describe trajectories of alcohol severity and environmental reward over a 16-month follow-up and examined whether environmental reward levels moderated the effectiveness of the interventions. RESULTS: Piecewise growth mixture modeling identified 2 trajectories of reward availability: low increasing (LR; n = 120) and high stable (HR; n = 273). Depressive symptoms, cannabis use, sensation seeking, and low life satisfaction were associated with a greater probability of classification in the LR trajectory. Alcohol severity was greater in the LR trajectory than the HR trajectory. For students in the LR trajectory, at 1, 6, and 12 months, BMI + SFAS led to greater increases in reward availability and reduced levels of alcohol severity compared with the BMI + RT and AO conditions and at 16 months compared with AO. CONCLUSIONS: Young adults with low levels of environmental reward are at heightened risk for greater alcohol severity and may show greater benefit from brief alcohol interventions that focus on increasing substance-free reward than individuals who are not deficient in reward availability.

Psychometric evaluation of the Reward Probability Index in emerging adult drinkers.

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, Behavior Therapy, 42, 2011, pp. 249-262) is a 20-item self-report rating scale that measures access to and ability to experience psychosocial reward. METHOD: The current studies sought to evaluate the psychometric properties of the RPI in 2 samples of emerging adult heavy drinkers. RESULTS: In Study 1, exploratory factor analysis in a sample of 393 college student drinkers supported a 2-factor model of the RPI (Reward Probability and Environmental Suppressors) after removal of redundant items, and corresponding subscales demonstrated good internal consistency. In Study 2, confirmatory factor analysis with 602 emerging adult drinkers recruited from the community supported the 2-factor model as best fitting after removal of one poor indicator, although absolute fit was only adequate. This 2-factor model demonstrated configural, metric, and scalar invariance across non-college and college subgroups as well as Black and White subgroups. Study 2 also demonstrated that the revised RPI subscales showed significant associations with measures of substance-free activity participation and enjoyment, anhedonia, and depressive symptoms. Furthermore, the study revealed the RPI Environmental Suppressors subscale predicted alcohol-related problems (ß = .25, p < .001) beyond demographic covariates, weekly drinking, and depressive symptoms. CONCLUSIONS: These studies provide evidence for the validity of the RPI as an efficient measure of access to reward among emerging adult heavy drinkers.

Statistically derived patterns of behavioral economic risk among heavy-drinking college students: A latent profile analysis.

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. A sample of 393 college students (60.8% female, 78.9% White/Caucasian) reporting at least 2 heavy drinking episodes in the previous month completed measures of alcohol use and problems, demographics, delay discounting, and alcohol reward value (alcohol demand and proportionate substance-related reinforcement). Latent profile analyses revealed that a 3-class solution provided the best fit to the data: a low reward value, high discounting (LRHD) class (n = 53), a moderate reward value, low discounting (MRLD) class (n = 214), and a high reward value, high discounting (HRHD) class (n = 126). Members of the HRHD class reported significantly greater alcohol consumption, past-month HED episodes, alcohol-related problems, and symptoms of alcohol use disorder than those in the MRLD and LRHD classes. The results suggest that there are 3 constellations of behavioral economic processes and that, consistent with the reinforcer pathology model, students who overvalue alcohol-related reward and discount the future more steeply are at the greatest risk for alcohol misuse and alcohol-related problems.
