The Effects of Alcohol Priming on the Subsequent Value of Alcohol.

OBJECTIVE: Previous research has investigated the effects of substance priming (i.e., substance exposure or preload) on the subsequent value of alcohol. Studies suggest that substance priming may serve as a cue, resulting in increased desire for the substance or drug-related behavior; however, results have been inconsistent. The current studies aimed to examine the effects of a priming dose of alcohol, compared with placebo, on the relative reinforcing effects of subsequent alcohol. METHOD: Undergraduate students (Study 1: N = 46 [33 women]; Study 2: N = 69 [50 women]) completed the Multiple Choice Procedure (MCP) during individual, lab-based sessions. The MCP was used to assess the relative reinforcing value of alcohol compared with concurrently available alternatives. Study 1 compared a standard dose of alcohol (one standard drink) with placebo, and Study 2 compared g/kg dosing of alcohol (controlling for gender) with placebo. RESULTS: Data revealed no statistically significant priming effect of alcohol on the subsequent value of alcohol in either study. CONCLUSIONS: The conditions under which alcohol priming does (and does not) occur are still not fully understood, and further systematic work is necessary to determine potential clinical utility.

Event-Specific Cannabis Use and Cannabis Use Motives.

BACKGROUND: Specific events such as Mardi Gras (MG) and St. Patrick's Day (SPD) have been identified as high-risk events for cannabis use. Further, some campuses may have traditions that are associated with more event-specific cannabis use. OBJECTIVES: Campus A has specific traditions regarding MG whereas Campus B has specific traditions regarding SPD and these campuses are differentially related to event-specific cannabis use (Buckner, Henslee, & Jeffries, 2015 ). Yet, little work has identified individual difference variables related to high-risk cannabis use events. METHODS: Current cannabis using undergraduates (N = 154) at two campuses completed an online survey of event-specific cannabis use motives, cannabis use, and cannabis-related problems. RESULTS: Campus A endorsed more MG-specific social and enhancement motives than Campus B. Campus A reported more socially, enhancement, coping, conformity, and expansion motivated cannabis use on MG than on SPD, whereas Campus B reported more socially and enhancement motivated cannabis use on SPD than on MG. Campus A was indirectly related to more MG-specific cannabis use through MG-specific social and enhancement motives. Conclusions/Importance: Event-specific cannabis motives are differentially related to specific high-risk cannabis use events and may be important therapeutic targets.

Assessing Freshman Engineering Students' Understanding of Ethical Behavior.

Academic dishonesty, including cheating and plagiarism, is on the rise in colleges, particularly among engineering students. While students decide to engage in these behaviors for many different reasons, academic integrity training can help improve their understanding of ethical decision making. The two studies outlined in this paper assess the effectiveness of an online module in increasing academic integrity among first semester engineering students. Study 1 tested the effectiveness of an academic honesty tutorial by using a between groups design with a Time 1- and Time 2-test. An academic honesty quiz assessed participants' knowledge at both time points. Study 2, which incorporated an improved version of the module and quiz, utilized a between groups design with three assessment time points. The additional Time 3-test allowed researchers to test for retention of information. Results were analyzed using ANCOVA and t tests. In Study 1, the experimental group exhibited significant improvement on the plagiarism items, but not the total score. However, at Time 2 there was no significant difference between groups after controlling for Time 1 scores. In Study 2, between- and within-group analyses suggest there was a significant improvement in total scores, but not plagiarism scores, after exposure to the tutorial. Overall, the academic integrity module impacted participants as evidenced by changes in total score and on specific plagiarism items. Although future implementation of the tutorial and quiz would benefit from modifications to reduce ceiling effects and improve assessment of knowledge, the results suggest such tutorial may be one valuable element in a systems approach to improving the academic integrity of engineering students.

Trauma-focused exposure therapy for chronic posttraumatic stress disorder in alcohol and drug dependent patients: A randomized controlled trial.

To test whether a modified version of prolonged exposure (mPE) can effectively treat posttraumatic stress disorder (PTSD) in individuals with co-occurring PTSD and substance dependence, an efficacy trial was conducted in which substance dependent treatment-seekers with PTSD (N = 126, male = 54.0%, White = 79.4%) were randomly assigned to mPE, mPE + trauma-focused motivational enhancement session (mPE + MET-PTSD), or a health information-based control condition (HLS). All participants were multiply traumatized; the median number of reported traumas that satisfied DSM-IV Criterion A for PTSD was 8. Treatment consisted of 9-12 60-min individual therapy sessions plus substance abuse treatment-as-usual. Participants were assessed at baseline, end-of-treatment, and at 3- and 6-months posttreatment. Both the mPE and mPE + MET-PTSD conditions achieved significantly better PTSD outcome than the control condition. The mPE + MET-PTSD and mPE conditions did not differ from one another on PTSD symptoms at end of treatment, 3-, or 6-month follow-up. Substance use outcomes did not differ between groups with all groups achieving 85.7%-97.9% days abstinent at follow-up. In regard to clinically significant improvement in trauma symptoms, 75.8% of the mPE participants, 60.0% of the mPE + MET-PTSD participants, and 44.4% of the HLS participants experienced clinically significant improvement at the end-of-treatment. Results indicate mPE, with or without an MET-PTSD session, can effectively treat PTSD in patients with co-occurring PTSD and substance dependence. In addition, mPE session lengths may better suit standard clinical practice and are associated with medium effect sizes. (PsycINFO Database Record

Celebrating St. Patrick's Day: Students' Expectations, Intent, and Behavior.

College students engage in risky alcohol use within a variety of contexts, including specific celebratory events. Student intentions and peer perceptions predict alcohol use; however, how these factors affect specific celebratory drinking may vary from typical alcohol use. The current study sought to better understand event-specific drinking among college students during St. Patrick's Day, as compared to Spring Break. Undergraduate students (N = 82) at a campus with a unique traditional celebration of St. Patrick's Day were surveyed. At Time 1, participants were asked to indicate how much alcohol they intended to drink and how much alcohol they expected other students to drink during St. Patrick's Day and Spring Break. At Time 2, students reported on actual alcohol consumption during both events. Results indicated that participants reported greater intent to consume, expectation of peer consumption, and actual alcohol consumption during St. Patrick's Day as compared to Spring Break. Neither sensation seeking nor impulsivity predicted alcohol use during either event. Findings are discussed in the context of understanding, preventing, and intervening with event-specific drinking among college students.

Event-specific cannabis use and use-related impairment: the relationship to campus traditions.

OBJECTIVE: Despite high rates of college cannabis use, little work has identified high-risk cannabis use events. For instance, Mardi Gras (MG) and St. Patrick's Day (SPD) are characterized by more college drinking, yet it is unknown whether they are also related to greater cannabis use. Further, some campuses may have traditions that emphasize substance use during these events, whereas other campuses may not. Such campus differences may affect whether students use cannabis during specific events. The present study tested whether MG and SPD were related to more cannabis use at two campuses with different traditions regarding MG and SPD. Further, given that Campus A has specific traditions regarding MG whereas Campus B has specific traditions regarding SPD, cross-campus differences in event-specific use were examined. METHOD: Current cannabis-using undergraduates (N = 154) at two campuses completed an online survey of event-specific cannabis use and event-specific cannabis-related problems. RESULTS: Participants used more cannabis during MG and SPD than during a typical weekday, typical day on which the holiday fell, and a holiday unrelated to cannabis use (Presidents' Day). Among those who engaged in event-specific use, MG and SPD cannabis use was greater than typical weekend use. Campus differences were observed. For example, Campus A reported more cannabis-related problems during MG than SPD, whereas Campus B reported more problems during SPD than MG. CONCLUSIONS: Specific holidays were associated with more cannabis use and use-related problems. Observed between-campus differences indicate that campus traditions may affect event-specific cannabis use and use-related problems.

The impact of campus traditions and event-specific drinking.

OBJECTIVE: Specific events (e.g., Spring Break, holidays) are associated with greater college student drinking. However, the ways in which specific events are celebrated at specific campuses may impact students' beliefs about the social acceptability of drinking during these events, which may impact students' event-specific drinking. The present study investigated whether two campuses with different traditions regarding St. Patrick's Day and Mardi Gras differed on event-specific normative beliefs, intent to drink, and actual alcohol consumption. METHOD: Undergraduate students at two campuses (N=570, 59% female) were surveyed pre- and post-events. Campus 1 has specific campus-wide traditions regarding St. Patrick's Day whereas Campus 2 has specific campus-wide traditions regarding Mardi Gras. Prior to the events, participants were asked to indicate how much they expected their peers to drink and how much alcohol they intended to drink themselves during these events. After the events, students reported how much alcohol they actually consumed during the events. RESULTS: Campus 1 reported greater intent to drink and actual drinking during St. Patrick's Day than Campus 2, whereas Campus 2 reported greater intent to drink and actual drinking during Mardi Gras than Campus 1. Campus 1 reported greater norms during SPD than Campus 2, whereas Campus 2 reported greater norms during MG than Campus 1. Event-specific norms did not moderate the relation between event and student event-specific drinking. CONCLUSION: Campuses with different event-specific traditions differed in intent to drink and actual event-specific drinking. Findings have important implications for campus-wide interventions and individual treatment.

Religious Coping and Psychological and Behavioral Adjustment After Hurricane Katrina.

Positive and negative religious coping are related to positive and negative psychological adjustment, respectively. The current study examined the relation between religious coping and PTSD, major depression, quality of life, and substance use among residents residing in Mississippi at the time of Hurricane Katrina. Results indicated that negative religious coping was positively associated with major depression and poorer quality of life and positive religious coping was negatively associated with PTSD, depression, poorer quality of life, and increased alcohol use. These results suggest that mental health providers should be mindful of the role of religious coping after traumatic events such as natural disasters.

Testing the effects of e-mailed personalized feedback on risky alcohol use among college students.

OBJECTIVE: Although research utilizing the Internet to intervene with college student drinkers is growing, this study is the first to investigate the use of a theoretically-based and empirically supported personalized feedback form delivered via a single e-mail to college students. METHOD: Students (n=191) completed measures of their alcohol use, related consequences, and peer perceptions at baseline and 6weeks after the intervention. Students were randomly assigned to receive either e-mailed personalized feedback or e-mailed generic feedback. RESULTS: Students who received e-mailed personalized feedback reported consuming significantly fewer drinks in a given week, as well as a fewer number of days being drunk in the previous 30days. They also exhibited a significant reduction in the number of days they perceived their peers to have drunk alcohol and in the amount of alcohol they perceived their peers to consume per drinking occasion. CONCLUSION: e-Mailed personalized feedback appears to help students become more aware of normative drinking behavior and reduce the quantity of alcohol they consume. Furthermore, e-mailed personalized feedback may be a cost-effective manner in which to intervene with college student drinkers.

Craving and physiological reactivity to trauma and alcohol cues in posttraumatic stress disorder and alcohol dependence.

The high comorbidity of posttraumatic stress disorder (PTSD) and alcohol dependence (AD) has been firmly established. Although laboratory studies have examined self-reported craving in response to trauma and alcohol cues, no studies have reported on alcohol-related physiological responding in response to trauma cues in PTSD-AD individuals. Using a cue reactivity paradigm, this study examined the impact of personalized trauma-image cues and in vivo alcohol cues on alcohol-related responding (e.g., salivation, craving) in individuals with PTSD and AD (n = 40). Participants displayed reactivity to both trauma and alcohol cues when compared to neutral cues, including increased self-reported craving and distress, as well as greater salivation. These findings suggest that through repeated pairings of trauma memories and alcohol consumption, salivation may become classically conditioned to trauma cues. Moreover, the fact that the trauma-alcohol cue combination elicited greater alcohol craving, salivary responding, distress, and arousal than either the trauma-neutral or neutral-alcohol cue combinations suggests that effects of the trauma and alcohol cues were additive in nature. Evidence that AD individuals with PTSD report increased alcohol craving and display greater salivation in response to trauma memories, supplements prior research indicating that PTSD-related negative emotion and trauma-related alcohol craving may play an important role in the maintenance of AD.

Exposure therapy for posttraumatic stress disorder in a residential substance use treatment facility.

Clinical lore abounds when discussing the issue of treating trauma-related symptoms in substance dependent clients. Historically, clinicians have wondered whether they should wait until the client has gained substantial abstinence from abused substances before initiating trauma treatment or if trauma treatment should be conducted during substance use treatment. Furthermore, questions arise with regard to exactly how trauma-related symptoms should be addressed and how trauma treatment should be incorporated into the recovery process. In this article, the growing literature suggesting that posttraumatic stress disorder (PTSD) can be treated concurrently with substance use disorders is reviewed. In addition, the unique challenges of implementing treatment for PTSD with substance dependent clients seeking treatment in a residential treatment facility are discussed. Specifically, we provide concrete suggestions about how to utilize prolonged exposure, a very effective treatment for PTSD, with clients in a residential substance use treatment facility, including use of the internet to facilitate exposure therapy.

Effects of reinforcer magnitude and alternative reinforcer delay on preference for alcohol during a multiple-choice procedure.

The Multiple-Choice Procedure [MCP; Griffiths, R.R., Troisi II, J.R., Silverman, K., Mumford, G.K., 1993. Multiple-choice procedure: an efficient approach for investigating drug reinforcement in humans. Behav. Pharmacol. 4, 3-13; Griffiths, R.R., Rush, C.R., Puhala, K.A., 1996. Validation of the multiple-choice procedure for investigating drug reinforcement in humans. Behav. Pharmacol. 4, 3-13] was developed to investigate the relationship between drug preferences and alternative reinforcers. The current study was designed to better characterize the relationships among reinforcer magnitude, delay associated with an alternative reinforcer, and preference for alcohol among a sample of undergraduate drinkers. Participants were 27 male undergraduates, over the age of 21, who reported engaging in at least three occasions of binge drinking over the previous month. All participants took part in a single laboratory session, during which six versions of the MCP questionnaire were administered. Across the versions, participants made a total of 180 discrete choices between three amounts of alcohol (12, 24, or 36 ounces of beer; deception was used to mask the fact that 36 ounces of beer would not actually be provided during the sessions) and escalating amounts of money ($0 to $20) delivered immediately or after a one-week delay. Response on the MCP varied as a function of the amount of alcohol available and the delay associated with the alternative monetary reinforcer, with the effect of the delay diminishing as the dose of alcohol increased. Results of the current study are consistent with previous laboratory studies of choice behavior and with behavioral economic theories of substance use.

Perceived consequences of cigarette use among college students.

The current study was designed to investigate the perceived consequences of cigarette smoking among a sample of college students. Participants (N=206) rated the negative consequences of smoking higher than the positive consequences on both the Decisional Balance Measure and the Smoking Consequences Questionnaire. While scales assessing the perceived positive consequences of cigarette smoking varied as a function of smoking status, the perceived negative consequences of smoking did not vary as a function of smoking status or stage of change. This pattern of findings is inconsistent with previous studies, which have reported that the relationship between the perceived positive and negative consequences of smoking shifts towards a more negative view as smokers become more motivated to change or actually quit smoking. The differential patterns of results across studies highlight the need for continued research on the relationship between the perceived consequences of cigarette use and actual smoking behavior among young adults who smoke but are not necessarily nicotine dependent.

Using national alcohol screening day to deliver personalized feedback: a pilot study.

The current study tested the effectiveness of using National Alcohol Screening Day (NASD) to deliver personalized feedback via mail. At-risk NASD participants were assigned to either personalized or generic feedback conditions and attended a 4-week follow-up. Results failed to find any group differences on alcohol-related variables. However, participants in the personalized group reported a reduction in the maximum number of drinks consumed on one occasion. The personalized group also had a more accurate view of the amount of alcohol their peers consumed. NASD is a vehicle to efficiently deliver feedback to individuals about their alcohol use; however, more research is needed to determine the types of feedback that would be most effective.
