Why get high? Coping and enjoyment motives mediate elevated cannabis demand and cannabis-related outcomes.

OBJECTIVE: Cannabis is the most used psychoactive substance among adolescents and is a public health concern. Cannabis demand is a quantifiable measure of the reinforcing value of cannabis and comprises two latent-factors-amplitude (maximum consumption) and persistence (sensitivity to increasing costs). Cannabis demand and cannabis motives are important predictors of adolescent cannabis use and associated problems; however, little is known about how these two facets of motivation are causally related. Cannabis motives are thought to represent the final common pathway to cannabis use and may explain why elevated demand is associated with use and consequences. The present study tested whether internal cannabis motives (coping and enjoyment) mediated longitudinal associations between cannabis demand, use (hours high), and negative consequences. METHOD: Participants aged 15-18 years old (n = 89, Mage = 17.0, SD = 0.9) who reported lifetime cannabis use completed online assessments of cannabis demand, motives, use and negative consequences at baseline, 3-month, and 6-month follow-up. RESULTS: PROCESS mediation models revealed that enjoyment motives mediated the association between amplitude and persistence and use. In addition, coping motives mediated the association between amplitude and negative consequences. CONCLUSIONS: These findings suggest that internal motives, while differentially related to aspects of demand and cannabis outcomes, are important in understanding adolescent cannabis use. Prevention efforts aimed at limiting access to cannabis and increasing access to substance-free activities may be important targets for adolescents. Further, cannabis interventions targeting specific motives for using (e.g., to cope with negative affect) may be important for reducing cannabis demand.

An exploratory factor analysis of an e-CHUG drinking motives scale with mandated students.

OBJECTIVE: Colleges maintain alcohol policies in response to student alcohol misuse, and sanctions for violating these policies often mandate students to attend alcohol education and/or counseling (Anderson & Gadaleto, 2021). Electronic Checkup to Go (e-CHUG) is a widely used online motivational intervention program that provides feedback to college students to encourage them to alter their drinking behaviors (eCheckup to Go, 2021). While measures included in e-CHUG have clear clinical utility, their psychometric properties have not been evaluated. The present study was designed to evaluate the factor structure and validity of the 18-item drinking motives scale included in the intervention. METHOD: Participants were 3,546 students from a large public university who were mandated to complete e-CHUG (58% male, MAge = 19.06, SDAge = 1.35) between 2013 and 2021. Students completed a battery of measures, including questions regarding alcohol consumption, drinking motives and consequences, and the Alcohol Use Disorders Identification Test (AUDIT). RESULTS: An exploratory factor analysis was conducted to investigate the structure of the drinking motives scale. Two factors were retained: The first factor represented coping motives, and the second factor represented a mixture of enhancement and social motives. Hierarchical regression analyses explored the associations between the retained drinking motives factors and alcohol-related variables. Both coping motives and enhancement/social motives positively and uniquely predicted drinking consequences and AUDIT scores. CONCLUSIONS: This study provides support for the construct and incremental validity of e-CHUG's drinking motives measure and could have important implications for the consideration of drinking motives during e-CHUG interventions.

A Systematic Review of Validated Measures of U.S.-Based Bystander Intervention-Related Constructs.

This review aimed to identify U.S.-based, construct-validated measures of bystander intervention. Following PRISMA-P guidelines, electronic databases were searched, and emails were solicited identifying 8,559 articles for title screening. Abstracts and full texts were double screened, resulting in 24 scales meeting inclusion criteria: (a) measured a bystander-related construct in a situation where there was a potential for actual or perceived imminent physical or emotional harm, (b) written in English, and (c) statistically validated on U.S. samples. Most scales addressed the domain of interpersonal violence (67%), with fewer relating to bias/bullying (8.2%), mental health crises (12.5%), and substance use (12.5%). Most scales (71%) assessed the "take action" step of the situational model. The modal construct represented was intent/willingness/likelihood to intervene (50%). The average number of items on a scale was 14, and most (79%) provided Likert-style response options. None of the validated scales assessing behavior first accounted for an opportunity. Sample sizes ranged from 163 to 3,397, with the modal setting from colleges. Overall, samples were young (21.8 years old), White (75%), women (64%), and heterosexual (89%). Results indicate the need to validate additional measures that capture the "interpreting the situation as problematic" step of the situational model. Scales also need to be validated using diverse samples, particularly within the mental health crisis domain. Across all domains, validated measures need to be developed that first account for an opportunity when measuring actual bystander behavior. The information gleaned can be used to assist researchers in selecting measures and guide future measure development.

Substance use behaviors among college students in the food service industry.

Objective: Food service employment is associated with substance use, risk of substance use disorders and various negative consequences. Previous research has not examined the substance use patterns of students employed in food service positions. Method: During Fall of 2018, 276 undergraduates completed an anonymous online survey regarding current employment status and substance use. Results: Compared to students employed in other positions, students in food service positions reported higher levels of drinking to cope with negative affect, negative urgency, workplace substance use, marijuana use, marijuana-related problems, and motives. Food service employment was also a significant predictor of marijuana use and related consequences. Conclusions: Students in food service positions, relative to other employment positions, report elevated substance use behavior, risk factors, and negative consequences. Food service employment also contributed variance to models accounting for marijuana use and related consequences. Prevention and intervention strategies should be investigated to mitigate risk for this population.

Latent class analysis of drinking game consequences among college drinkers.

Participation in drinking games has been identified as one specific alcohol-related context linked to increased risk for heavier alcohol consumption and negative consequences among college students. Despite advances in drinking game research, questions remain about the different types of individuals at risk from participating. The current study utilized latent class analysis to classify individuals based on their endorsement of eight negative drinking game consequences from the Hazardous Drinking Games Measure. Analyses included identification of classes among 656 college students, followed by covariate analyses regressing class membership on motives for playing drinking games, general drinking motives, impulsivity facets, general problematic alcohol use, and specific drinking game behaviors. A total of three classes were identified, including a class with the fewest number of problems, a class with higher rates of hangovers and becoming sick, and a class with relatively higher rates of a majority of the other consequences. Classes differed in endorsement of motives, impulsivity facets, general problematic consumption, and drinking game behaviors. Generally, coping, conformity, and social general drinking motives; conformity and enhancement and thrills motives for playing drinking games; the impulsivity facet of negative urgency; the number of drinks consumed while playing drinking games; playing consumption type drinking games; and general problematic alcohol use were associated with more problematic class membership. Results highlight distinct classes of individuals at risk from drinking game participation. Recommendations for future studies and potential prevention and intervention efforts are also discussed.

An investigation of the reinforcing value of video game playing relative to concurrently available monetary alternatives.

OBJECTIVE: Video game playing (VGP) has received recent attention as a result of sharing many similarities with other addictive behaviors. Behavioral economic models are commonly used to understand drug use and other addictive behaviors and may similarly inform conceptual models of VGP. METHOD: The present study employed behavioral economic principles to conceptualize relative reinforcing value for playing video games compared to concurrently available alternative potential monetary reinforcers. Participants (N = 81) played three video games picked to represent games of low, medium, and high quality (i.e., OutDrive, Forza Motorsport 1, and Forza Motorsport 7), with quality designations based on the research teams' assessment of various features of the game (e.g., graphics, sound, immersion) as well as the game's market value at the time the study was conducted. Participants played each game for 10 min and completed Visual Analog Scales and a multiple-choice procedure (MCP) designed to assess relative reinforcing value at various time points during and after each session. RESULTS: As hypothesized, both subjective ratings and relative reinforcing value increased as the designated quality of the game increased. More specifically, the high-quality game was rated as more fun and likable and had a higher MCP crossover point than the medium and low-quality games. CONCLUSIONS: Like other behavioral addiction studies, results suggest that methodologies and behavioral measures commonly used in drug administration literature can be effectively applied to VGP.

Relations among motives, negative urgency, and mindfulness skills in college drinkers.

Heavy alcohol use continues to be a common problem among the college student population, and numerous negative consequences can be attributed to student drinking. Several factors, including drinking motives and impulsivity, have been studied to better understand college drinking behaviors. Research has identified that coping motives (i.e., drinking to reduce negative affect) and negative urgency (i.e., the tendency for rash reaction in response to negative affect) are both closely linked to alcohol-related problems and to one another. The primary purpose of this study was to test if mindfulness skills moderate the relation between negative urgency and drinking to cope. To test for moderation, 683 college student drinkers responded to self-report measures of drinking behaviors, drinking motives, impulsivity, and daily utilization of mindfulness skills. Four separate regression models tested for the mindfulness skills of observing, describing, acting with awareness, and accepting without judgment as potential moderators to the relation between negative urgency and coping motives. The mindfulness skill of accepting without judgment significantly moderated (i.e., dampened) the positive relation between negative urgency and drinking to cope. Results may be useful in developing targeted intervention and prevention efforts to test among students, as skills training may benefit individuals with long-standing impulsive personality traits who engage in the traditionally problematic behavior of drinking to cope.

Measurement of substance-free reinforcement in addiction: A systematic review.

A robust body of theoretical and experimental work highlights the influence of alternative, substance-free rewards on decisions to use alcohol and other drugs. However, translational applications have been limited in part by the lack of consensus on how to measure substance-free reinforcement in applied and clinical settings. The current study summarizes extant research utilizing self-report reinforcement or reward methodologies, and critically reviews the psychometric properties of the available measures. These studies (N = 50) fell into three categories: measures of recent substance-related and substance-free activity participation and enjoyment (n = 32), measures of time or monetary resource allocation (n = 15), and rating scale measures of reward availability and experience (n = 8). The available research suggests that, consistent with experimental laboratory research and with behavioral economic predictions, there is an inverse relation between substance-free reinforcement and substance use. These studies also support the clinical utility of these measures in predicting substance use severity and course. Reinforcement measures could be improved by enhancing content validity, multimethod convergent validity, and generalizability.

Evaluation of the psychometric properties of the cannabis use disorders identification test - revised among college students.

OBJECTIVE: Cannabis use is common among college students and is associated with a variety of negative consequences. The Cannabis Use Disorders Identification Test Revised (CUDIT-R) is an 8-item screening instrument designed to identify potentially problematic or harmful recent cannabis use. The purpose of the current study was to evaluate the internal consistency and validity of the CUDIT-R in a sample of college students who reported recent cannabis use (past 30 day). METHODS: Participants (n = 229) completed the CUDIT-R and measures of smoking behavior (Daily Smoking Questionnaire; DSQ), cannabis related consequences (Marijuana Problem Index; MPI), and problematic cannabis use (self-reported DSM-5 Cannabis Use Disorder Criteria). RESULTS: The CUDIT-R showed good internal consistency and concurrent validity with cannabis related outcome measures including; frequency of use, cannabis related consequences, and total DSM-5 criteria endorsed. The CUDIT-R also showed evidence of discriminant validity across DSM-5 severity classifications, achieved high levels of sensitivity (0.929) and specificity (0.704), and excellent area under the receiver operating characteristics curve when using a cutoff score of six. All items displayed high levels of discrimination and varied in terms of difficulty and information provided. CONCLUSIONS: Overall, the CUDIT-R appears to be a reliable and valid screening measure when used to identify college students at risk for cannabis related problems. Future research should further evaluate the sensitivity and specificity of the CUDIT-R threshold scores with more rigorously established DSM-5 diagnoses, and across a range of populations. Research on the utility of using the CUDIT-R for measuring treatment outcomes is also warranted.

Differential Role of Cannabis Use Motives in Predicting Impairment Across Three Measures.

OBJECTIVE: Previous research has demonstrated the utility of motivational models of cannabis use to predict the frequency of use and associated negative consequences. However, few existing studies have simultaneously investigated a range of motives across different measures of use-related problems, which limit the ability to assess the differential role various motives play. The purpose of the current study was to examine cannabis use motives as predictors of three measures of cannabis use risk. METHOD: Participants (N = 229) who reported cannabis use within the past 30 days completed the Marijuana Motives Measures, as well as measures of typical smoking behavior and risk: Cannabis Use Disorders Identification Test-R (CUDIT-R; screening measure of hazardous cannabis use), Marijuana Problem Index (MPI; measure of broad psychosocial problems), and cannabis use disorder according to criteria from the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). RESULTS: Cannabis use motives-particularly coping, enhancement, and conformity-contributed to the prediction of cannabis-related impairment beyond gender and the frequency of recent use. Among the motives scales, coping emerged as the most robust predictor across the three impairment measures and was the only motive to add unique variance to predictions of DSM-5 symptoms. Enhancement and conformity motives were predictive of the screening measure (CUDIT-R scores), and enhancement motives was also predictive of a measure of broad psychosocial problems related to cannabis use (MPI scores). CONCLUSIONS: The results highlight the differential role various marijuana use motives play across related but distinct measures of impairment.

Using the Multiple-Choice Procedure to Measure the Relative Reinforcing Efficacy of Gambling: Initial Validity Evidence Among College Students.

The multiple choice procedure (MCP) is used to assess the relative reinforcing value of concurrently available stimuli. The MCP was originally developed to assess the reinforcing value of drugs; the current within-subjects study employed the MCP to assess the reinforcing value of gambling behavior. Participants (N = 323) completed six versions of the MCP that presented hypothetical choices between money to be used while gambling ($10 or $25) versus escalating amounts of guaranteed money available immediately or after delays of either 1 week or 1 month. Results suggest that choices on the MCP are correlated with other measures of gambling behavior, thus providing concurrent validity data for using the MCP to quantify the relative reinforcing value of gambling. The MCP for gambling also displayed sensitivity to reinforcer magnitude and delay effects, which provides evidence of criterion validity. The results are consistent with a behavioral economic model of addiction and suggest that the MCP could be a valid tool for future research on gambling behavior.

A systematic review of the free-pour assessment: Implications for research, assessment and intervention.

Excessive alcohol consumption is a major concern. Alcohol consumption data are typically collected via self-report questionnaires. However, research has suggested that individuals are unable to identify a standard drink size and that their self-report may be influenced by certain environmental conditions, calling into question the reliability and validity of self-report. The free-pour is an objective measure that may provide a clearer picture of current alcohol consumption trends, individuals' knowledge of standard drink sizes, and accuracy of self-report. This systematic review of existing free-pour assessment methods suggests that individuals are unable to identify and pour standard drink sizes, with the largest discrepancies occurring for liquor and wine pours and pours into larger and wider glasses. Additional variables that appear to influence pouring behavior are gender, pouring location (e.g., home or laboratory), pouring task (e.g., selecting a line or physically pouring), and drinking history; however, additional research is necessary to better understand the effects of these variables on pouring behavior. These findings have important implications for the accuracy of self-report measures, as well as clinical implications for alcohol use screenings, alcohol education courses, and brief interventions for alcohol use. The systematic review concludes with recommendations for practical applications and future research of the free-pour assessment. (PsycINFO Database Record

Suicide Ideation, Alcohol Consumption, Motives, and Related Problems: Exploring the Association in College Students.

Previous findings on the relationship between suicide ideation (SI) and alcohol misuse among college students are inconsistent, leading to conflicting clinical implications. We aimed to clarify this relationship in order to determine the utility of regarding alcohol misuse as a risk factor for SI in this population. Unselected college students (N = 545) completed an online survey including measures of alcohol consumption, problems, drinking motives, SI, and related variables. Our results suggest alcohol misuse is not a correlate of SI among college students; therefore, one should not assume that students who misuse alcohol are necessarily at increased risk for SI.

Diversion of prescription stimulants among college students: An initial investigation of injunctive norms.

Nonmedical use of prescription stimulants (NMUPS) is an increasing problem among the college student population. Despite recent increases in stimulant prescriptions, little research has examined diversion of prescription stimulants among college students. The purpose of the current exploratory study was to compare normative beliefs about the frequency and motives of NMUPS among a college student sample. Participants were 121 college students who reported having a current prescription for a prescription stimulant. Participants completed online surveys and reported occasions of diversion behavior along with ratings of perceived approval for NMUPS and associated motives. Participants with a history of diversion were more likely to rate their close friends as more approving of more frequent NMUPS, and more approving of various motives for NMUPS. Perceived approval of NMUPS and NMUPS motives among parents and typical university students was similar across diversion groups, with parents and university students being rated as more approving of NMUPS for educational purposes. These findings extend the use of social norms theory to a new behavior while adding to our understanding how those who divert their medication differ from those who do not. Future studies should seek to establish a causal relationship between perceived approval for NMUPS and diversion behaviors. These findings also suggest that future research should focus on the feasibility and impact of social norms intervention for NMUPS and medication diversion.

Normative influences on the nonmedical use of prescription stimulants among college students.

Recent epidemiological data indicate an increasing trend in the nonmedical use of prescription drugs among college students. The nonmedical use of prescription drugs involves using a prescription medication without a prescription, or using the medication in a manner inconsistent with a health care provider's instructions. Among college students, prescription stimulants have the highest ratio of nonmedical to medical use and the highest rate of illicit selling and trading on college campuses. The increased prevalence is accompanied by increased risk, as 18-25-year-olds have the highest rate of emergency department visits for nonmedical use of prescription stimulants (NMUPS). To date, no study has examined the impact of social norms on NMUPS. The social norm theory has accounted for other health related behaviors (e.g., alcohol and marijuana use) and has been utilized in brief interventions targeting risky health behaviors. The current study examined the prevalence of self-reported NMUPS among college students and the impact of perceived social norms on NMUPS. The current study included 959 participants who completed an online survey that assessed for NMUPS, self-approval for NMUPS, and perceived descriptive and injunctive norms for NMUPS. Similar to previous research on alcohol and marijuana use, students overestimated the prevalence of NMUPS and this overestimation was related to past-year NMUPS. Perceived close friend and parental approval of NMUPS was positively related to self-approval and past-year NMUPS. Overall, the study broadens the existing literature on NMUPS and provides a platform for developing brief interventions that target this risky behavior. (PsycINFO Database Record

A behavioral economic analysis of the nonmedical use of prescription drugs among young adults.

The nonmedical use of prescription drugs is a widely recognized public health issue, and young adults are particularly vulnerable to their use. Behavioral economic drug purchase tasks capture an individual's strength of desire and motivation for a particular drug. We examined young adult prescription drug purchase and consumption patterns using hypothetical behavioral economic purchase tasks for prescription sedatives/tranquilizers, stimulants, and opiate pain relievers. We also examined relations between demand, use frequency, and Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) substance use disorder (SUD) symptoms, and sex differences in these relations. Undergraduate students who endorsed past-year prescription drug use (N = 393) completed an online questionnaire for course credit. Measures assessed substance use frequency and DSM-5 SUD symptoms. Hypothetical purchase tasks for sedatives, stimulants, and pain relievers assessed participants' consumption and expenditure patterns for these substances across 25 prices. Past-year prescription sedative, stimulant, and pain reliever use was endorsed by 138, 258, and 189 participants, respectively. Among these users, consumption for their respective substance decreased as a function of ascending price, as expected. Demand indices for a prescription drug were associated with each other and with use frequency and SUD symptoms, with variability across substances but largely not by sex. In addition, demand for prescription pain relievers differentially predicted symptoms independent of use, with differences for females and males. In conclusion, hypothetical consumption and expenditure patterns for prescription drugs were generally well described by behavioral economic demand curves, and the observed associations with use and SUD symptoms provide support for the utility of prescription drug purchase tasks.

Modeling motivations for non-medical use of prescription drugs.

INTRODUCTION: Non-medical use of prescription drugs (NMUPD) is a growing problem among college-aged individuals. Motivations for use of a substance have been shown to predict consumption behavior across a variety of substances, but research on motivations for engaging in NMUPD is limited. We hypothesize that Confirmatory Factor Analysis (CFA) would support a two-factor latent structure for motivations (self-treatment and recreational) for NMUPD across three classes of drugs (stimulants, tranquilizers and sedatives, and pain relievers). METHODS: Data were collected from 1016 undergraduates attending a large southeastern university via an online survey. Motivations for use were subjected to a CFA for those participants who reported past-year use of each drug class (tranquilizer and sedative use n=138, pain reliever use n=189, and stimulant use n=258). RESULTS: Model fit varied across drug class. A two-factor model emerged for both pain relievers and stimulants, and each factor was positively correlated with one another and with frequency of use for both drug classes. A two-factor model was not a good fit for tranquilizers and sedatives. CONCLUSIONS: Motives for NMUPD are a relatively understudied construct. Although our initial results suggest that a proposed framework consisting of self-treatment and recreational motives might have some utility in explaining the use of stimulants and pain relievers, more research is needed to characterize motives for tranquilizers and sedatives. Additional research is also needed to develop assessment measures that capture the full range of motives for all three classes of NMUPD.

Measuring alcohol-related consequences and motives among students attending Historically Black Colleges and Universities.

INTRODUCTION: College student drinkers have the propensity to engage in heavy alcohol consumption. These consumption patterns can be problematic given the well-established relationship between heavy drinking and negative consequences of alcohol consumption. Though the research on college student drinking is abundant, much of the work conducted has been with Caucasian samples and less so with African American samples or at Historically Black Colleges and Universities (HBCUs). METHODS: The current paper assessed the internal reliability and concurrent validity of two popular measures of alcohol related negative consequences (CAPS-r and YAACQ) and a measure of drinking motives (DMQ-R) within a HBCU sample. RESULTS: Total scores for the CAPS-r and YAACQ and all five subscales of the DMQ-R were internally reliable as determined by Cronbach's alpha. Correlations and regressions established concurrent validity for both measures of negative consequences as well as the subscales for the DMQ-R. CONCLUSIONS: Findings support the use of these measures in the assessment of negative consequences and motivations for alcohol consumption within a HBCU population.

Associations among depressive symptoms, drinking motives, and risk for alcohol-related problems in veterinary students.

Hazardous alcohol consumption among medical students appears to occur at a level comparable to the general population; however, among medical students, it has been found that the motivation to use alcohol partially stems from unique stressors related to their professional training. Although veterinary students may also experience psychological distress in association with their training, little work has focused on the way that these students use alcohol to cope with their distress. The current study sought to examine the severity of depressive symptoms and alcohol consumption among veterinary students as well as students' specific motives for drinking alcohol. The majority of our sample reported experiencing at least one depressive symptom, and a significant proportion engaged in high-risk drinking, with men reporting more harmful alcohol use patterns. Drinking motives related to managing internal bodily and emotional states accounted for variance in drinking patterns. Further, drinking to ameliorate negative emotions partially accounted for the relationship between psychological distress and high-risk drinking. The results of this study suggest that depressive symptoms among veterinary students may be related to harmful drinking patterns, due to alcohol being used as a coping mechanism to regulate emotions. The findings from this study can be used to develop targeted interventions to promote psychological well-being among veterinary students.

Beyond risky alcohol use: screening non-medical use of prescription drugs at National Alcohol Screening Day.

INTRODCUTION: Recent epidemiological data has indicated an increasing trend in the non-medical use of prescription drugs (NMUPD) among college students. NMUPD has shown a strong relationship with heavy alcohol use and associated negative consequences. Despite the trends and association with other risky behavior, there remain large gaps in the literature regarding this hazardous behavior. To date, no study has examined the prevalence of NMUPD among student attending National Alcohol Screening Day (NASD), and few studies have explored motives contributing to NMUPD, as well as the relationship between motives, NMUPD, and alcohol use. METHODS: The current study examined the prevalence and motives for NMUPD among undergraduate students (N=128) attending NASD. RESULTS: Overall, 42% of the sample reported NMUPD at least once in their lifetime, 29.7% at least once in the past year, and 18.0% reported simultaneously engaging in alcohol consumption and NMUPD. Pain relievers were the most frequently used drug class for lifetime use, and stimulants were the most frequently reported for past year use. Most students reported NMUPD for functional reasons. Students that engaged in binge drinking were three times more likely to report NMUPD. CONCLUSIONS: The findings from the current study suggest that events like NASD may provide a platform for screening and discussing NMUPD, and its associated risk with heavy alcohol use.
