Cocaine Effect Expectancies among Patients with Cocaine Use Disorder with and without Adult Attention Deficit Hyperactivity Disorder: Are There Any Relevant Differences?

Abstract
Cocaine use could be modulated by drug expectancies based on previously experienced subjective effects. Some patients perceive a paradoxical calming effect after cocaine use. This study was performed to explore cocaine effect expectancies in patients diagnosed with cocaine use disorder, with and without co-occurring adult attention deficit hyperactivity disorder (ADHD). Secondly, we sought to empirically determine the presence of this paradoxical calming effect after cocaine use in patients with co-occurring adult ADHD to identify the individuals most at risk of cocaine use and relapse. Cross-sectional study using a consecutive sampling method of patients diagnosed with cocaine use disorder (n = 221) treated at public therapeutic communities in Andalusia (Spain). Participants completed a battery of instruments to assess the following variables: cocaine effect expectancies, paradoxical calming effect, adult ADHD, and other co-occurring psychiatric disorders. A multivariate binary logistic regression analysis showed that two variables, the paradoxical calming effect and antisocial personality disorder (ASPD), were independently associated with the probability of being diagnosed with adult ADHD (OR = 3.43, 95% CI = 1.88-6.26 and OR = 3.42, 95% CI = 1.30-8.95, respectively). The presence of a paradoxical calming reaction to cocaine and/or a diagnosis of ASPD in patients with cocaine use disorder increases the diagnostic suspicion of co-occurring adult ADHD.

Abstract
Substance use disorders and affective disturbances often covary. Even momentary experiences of negative affect (NA) appear linked with substance use. While strong evidence of these relations exists, NA might bias endorsements of substance use due to hindered recall and reporting processes. This hypothesis warrants further research, as accurate assessment of substance-related variables is crucial in both research and treatment settings. The present study examined the influence of NA on reporting of cannabis variables using an affect-induction paradigm. Over 700 individuals recruited from Amazon's MTurk participated. After reporting demographics and baseline affect, participants were randomly assigned to either a NA induction or control condition. Follow-up measures assessed post-induction affect and cannabis-related variables. Results revealed that the NA induction task significantly increased NA and decreased positive affect relative to the control condition. Participants assigned to the NA induction reported greater negative cannabis expectancies and more cannabis problems, even after controlling for age and educational attainment. Cannabis use and cannabis problems appeared positively related. Future research should continue to assess for the influence of NA in reporting of cannabis variables. Should subsequent work find differences in reporting of substance use that appear to covary with negative affect, clinicians and researchers alike should be mindful of the implications of potentially biased reporting on assessment, intervention, and research outcomes.

Spinella TC, Bartholomeusz J, Stewart SH, Barrett SP. Perceptions about THC and CBD effects among adults with and without prior cannabis experience. Addict Behav 2023; 137:107508.

Abstract
BACKGROUND Cannabis is associated with a range of therapeutic and non-therapeutic, positive and negative effects. While some benefits and harms may be specific to individual cannabinoid constituents (THC, CBD), individual expectancies may also play a role. OBJECTIVES Evaluate the extent to which individuals hold expectancies about the effects of CBD, THC, and THC & CBD combined, and whether this differs with prior cannabis experience. METHODS Canadian adults (N = 345; n = 58 no prior cannabis use, n = 287 prior cannabis use) completed a Qualtrics survey. Participants provided information regarding their expectancies about the effects of cannabinoids (THC, CBD, THC & CBD combined) via a 15-item questionnaire, which included various therapeutic (e.g., helps with pain) and non-therapeutic positive (e.g., enhances positive feelings) and negative (e.g., risk for addiction) effects. They recorded their perceptions about the effects of each cannabinoid on a scale (0="definitely not true", 10="definitely true"). Data was analyzed using linear mixed models. RESULTS For most therapeutic effects, CBD-containing products (CBD, THC & CBD) were rated higher than THC. For most positive and negative non-therapeutic effects, THC-containing products (THC, THC & CBD) were rated higher than CBD. Those with prior cannabis use (vs no prior use) rated all cannabinoids higher regarding their association with many therapeutic and positive effects, while endorsing weaker expectancies about their role in some negative effects. CONCLUSIONS Adults endorsed stronger expectancies that CBD-containing products are responsible for producing a rage of therapeutic effects. Those with prior cannabis use experience tended to emphasize the benefits and minimize potential harmful effects of cannabinoids.

Abstract
Objective: To gain information on the marijuana experiences and expectancies of youth in an urban Indian area, which may be used for forming the framework for the development of effective primary prevention strategies in the future. Method: This was a cross-sectional study conducted in various colleges of Mumbai; 260 students from three colleges who were above 18 years were selected by systematic random sampling. The participant had to fill a sociodemographic questionnaire and marijuana effect expectancy questionnaire (MEEQ-B) and it was analyzed by using the SPSS software. Results: A significant association was found between negative marijuana expectancies and type of family, with cannabis users and non-users, who want to try cannabis and those who are aware of the legal issues and harmful effects of cannabis. Conclusion: Preventive drug education should begin in early adolescence and should deter or delay drug use through changes in knowledge, attitude, behavior, and expectation. Adolescent drug education must meet the needs of those naive to drugs as well as those experiencing initial drug exposure. This is the first study which highlights the youth experiences and expectancies about marijuana in India.

Abstract
Background The popularity of ketamine for recreational use has been increasing in Asia, including Taiwan. Still, little known about the pattern of ketamine expectancies and whether such patterns are related to ketamine use. This study aimed to examine whether the positive and negative ketamine expectancies are differentially associated with ketamine-using behavior, and whether such relationship may differ by early-onset use of tobacco or alcohol. Methods Participants were recruited using respondent-driven sampling (RDS) among regular tobacco and alcohol users, aged 18 to 50, residing in Taipei from 2007 to 2010. Totally 1115 participants (with an age distribution skewed to the right, median = 26; interquartile range: 22–32) had information on substance use and completed a 12-item ketamine expectancies questionnaire (with 6 positive and 6 negative statements). Using two axes of High and Low expectancies, the four combinations of binary positive and binary negative ketamine expectancies were created. Each participant’s drug-using experience was categorized into illicit drug naïve, exclusive ketamine use, polydrug ketamine use, or other illicit drug use. Using the weights in the network output by RDS Analysis Tool, multivariable logistic regression analysis was then conducted. Results The weighted prevalence was 2.4% for exclusive ketamine use, 9.0% for polydrug ketamine use, and 9.1% for the other illicit drug use. Ketamine users (11.4%) had greater positive expectancies and lower negative expectancies, particularly the combination of High Positive with Low Negative, as compared to the illicit drug-naïve or other illicit drug users. After adjustment for early-onset tobacco (or alcohol) use and sociodemographic characteristics, High Positive, Low Negative, and their combination of High Positive-Low Negative expectancies remained strongly associated with ketamine uses, without evidence of moderation from early-onset use of tobacco or alcohol. Conclusions Positive and negative ketamine expectancies were associated in opposite directions with ketamine use, independent of early-onset use of tobacco or alcohol. Our results indicate ketamine expectancies as possible targets for future intervention and prevention of ketamine use, with a less confrontational feedback on decreasing an individual’s positive expectancies is essential in preventing young people from the initiation of ketamine use.

Abstract
BACKGROUND The bioSocial Cognitive Theory (bSCT) hypothesizes two pathways linking dimensions of impulsivity to substance use. The first predicts that the association between reward sensitivity and substance use is mediated by positive outcome expectancies. The second predicts that the relationship between rash impulsiveness and substance use is mediated by refusal self-efficacy. This model has received empirical support in studies of alcohol use. The present research provides the first application of bSCT to a cannabis treatment population and aims to extend its utility to understanding cannabis use and severity of dependence. DESIGN 273 patients referred for cannabis treatment completed a clinical assessment that contained measures of interest. SETTING A public hospital alcohol and drug clinic. MEASUREMENTS The Sensitivity to Reward Scale, Dysfunctional Impulsivity Scale, Cannabis Expectancy Questionnaire, Cannabis Refusal Self-Efficacy Questionnaire and Severity of Dependence Scale-Cannabis were completed, along with measures of cannabis consumption. FINDINGS The bSCT model provided a good fit to the data for cannabis use and severity of dependence outcomes. The association between reward sensitivity and each cannabis outcome was fully mediated by positive cannabis expectancies and cannabis refusal self-efficacy. The relationship between rash impulsiveness and each cannabis outcome was fully mediated by cannabis refusal self-efficacy. CONCLUSIONS Findings support the application of the bSCT model to cannabis use and dependence severity and highlight the important role of social cognitive mechanisms in understanding the association between impulsivity traits and these outcomes. The differential association of impulsivity traits to social cognition may assist targeted treatment efforts.

Abstract
BACKGROUND AND OBJECTIVES The acquired preparedness model (APM) integrates personality trait research and psychosocial learning, which are theorized to ultimately increase risk for problematic substance use outcomes. METHODS The present study uses the APM to examine the potential mediational role of positive and negative expectancies on the relationship between impulsivity and two marijuana outcomes (ie, frequency of use and marijuana use disorder [MUD] symptom count) among an at-risk sample of young adults with history of antisocial behavior and substance use in adolescence and their siblings (n = 312). RESULTS Results suggest a significant indirect effect of sensation seeking on recent marijuana use through positive marijuana expectancies. There also was a significant indirect effect of sensation seeking on past-year MUD symptoms through positive expectancies. No significant indirect effects through negative expectancies were found for either outcome. DISCUSSION AND CONCLUSIONS Our findings are consistent with the APM and suggest that higher sensation seeking is related to increased positive beliefs about marijuana outcomes, which is related to higher marijuana use and more MUD symptoms. SCIENTIFIC SIGNIFICANCE These findings suggest that positive expectancies are an important risk factor for marijuana use and misuse, particularly for at-risk individuals with elevated rates of sensation seeking. Positive marijuana expectancies may be important to address in interventions for at-risk individuals. (Am J Addict 2018;XX:1-6).

Abstract
OBJECTIVES The aim of this study was to test a new theoretical model of cannabis use incorporating biologically-based personality traits and social cognition. This biosocial cognitive theory (bSCT) has robust support in alcohol studies, but has not been applied to cannabis. The model proposes two pathways linking dimensions of impulsivity to cannabis use. The first predicts that the association between Reward Sensitivity (SR) and cannabis use is mediated by positive outcome expectancies. The second predicts that the relationship between Rash Impulsiveness (RI) and cannabis use is mediated by cannabis refusal self-efficacy. An extended version of this model was also tested and included a third pathway linking Punishment Sensitivity (SP) to cannabis use via higher negative outcome expectancies. METHOD Participants were 252 18-to-21-year-olds who completed questionnaires assessing cannabis use, personality and social cognition. Theoretical models were tested using structural equation modeling. RESULTS The bSCT model provided a good fit to the data (CFI=0.95; RMSEA=0.07; SRMR=0.06). Positive cannabis expectancies and refusal self-efficacy partially mediated the association between SR and cannabis use (p<0.05). Cannabis refusal self-efficacy fully mediated the relationship between RI and cannabis use (p<0.05). The addition of a third SP pathway did not improve model fit. CONCLUSIONS Consistent with alcohol studies, the association between impulsivity and cannabis use is largely mediated by social cognition. The bSCT may provide novel insights to inform prevention and treatment of problematic cannabis use.

Abstract
This study examined marijuana-related cognitions and marijuana use in African-American (AA) and European-American (EA) girls, with the aim of characterizing their interrelationships from early to late adolescence. Identifying differences by race in these relationships would have implications for tailoring interventions to specific subgroups. Data were drawn from the Pittsburgh Girls Study, an urban community sample (56.8% AA, 43.2% EA; n = 2,172) recruited at ages 5-8 years and assessed each year. Cross-lagged panel models were conducted separately by race to identify patterns of association between marijuana use and related cognitions (i.e., intentions to use, positive attitude toward use, positive and negative expectancies) assessed at ages 12-17 years. Results indicated that AA girls consistently reported higher negative expectancies than EA girls and greater intention to use marijuana, but they did not differ from EA girls on positive expectancies. In cross-lagged models, bidirectional effects between negative expectancies and marijuana use were observed in AA and EA girls across all ages, and at most ages for intentions to use, but were largely absent in both groups for positive attitude. Bidirectional effects of marijuana use with positive expectancies were observed only in AA girls at certain ages. Overall, results demonstrate more similarities than differences between AA and EA girls in the longitudinal associations between marijuana-related cognitions and marijuana use. Results highlight the role of negative expectancies as shaping and being shaped by marijuana use. Interventions that target negative expectancies to reduce marijuana use may be useful for AA and EA adolescent girls. (PsycINFO Database Record

Abstract
BACKGROUND The present research examines anticipated consequences of ceasing or reducing marijuana use with initial development and psychometric validation of a measure of marijuana cessation expectancies. METHODS The 46-item Marijuana Cessation Expectancies Questionnaire (MCEQ) was initially developed from the content validity analysis of free responses about expected outcomes of stopping and decreasing marijuana use generated by 94 participants. The closed-ended MCEQ was subsequently administered to 151 non-treatment seeking regular marijuana users (used on M=64.7% of the prior 60days, SD=25.1%;Mage=21.4, SD=3.96; 38.4% female). RESULTS Exploratory factor analyses identified six MCEQ factors that accounted for 61% of variance, which were related to expected improvement in: 1) performance/motivation, 2) problems with authority, and 3) interpersonal functioning, and expected worsening of 4) mood states and 5) fun experiences, and 6) changes in appetite/weight from cessation/reduction of marijuana use. Internal consistency of full scale items was good (α=0.86) and moderate to high for all factors (α's=0.60-0.89). The MCEQ items showed good concurrent validity with key measures and incremental associations with change indices (prior history of cessation/reduction attempt, benefits of reduction, importance of change), beyond the effects of marijuana use expectancies. CONCLUSIONS These data provide initial support for the MCEQ and suggest it is closely linked to reduction/cessation decisions in marijuana users. MCEQ may be used clinically to enhance existing behavioral treatments and motivational interventions for problem marijuana use.

Abstract
BACKGROUND Chronic methamphetamine use may lead to changes in reward-related function of the ventral striatum and caudate nucleus. Whether methamphetamine-dependent individuals show heightened reactivity to positively valenced stimuli (i.e. positive reinforcement mechanisms), or an exaggerated response to negatively valenced stimuli (i.e. driven by negative reinforcement mechanisms) remains unclear. This study investigated neural functioning of expectancy and receipt for gains and losses in adults with (METH+) and without (METH-) histories of methamphetamine dependence. METHODS Participants (17 METH+; 23 METH-) performed a probabilistic feedback expectancy task during blood-oxygen level-dependent (BOLD) functional magnetic resonance imaging (fMRI). Participants were given visual cues probabilistically associated with monetary gain, loss, or neutral outcomes. General linear models examined the BOLD response to: (1) anticipation of gains and losses, and (2) gain and loss monetary outcomes. RESULTS METH+ had less BOLD response to loss anticipation than METH- in the ventral striatum and posterior caudate. METH+ also showed more BOLD response to loss outcomes than to gain outcomes in the anterior and posterior caudate, whereas METH- did not show differential responses to the valence of outcomes. DISCUSSION METH+ individuals showed attenuated neural response to anticipated gains and losses, but their response to loss outcomes was greater than to gain outcomes. A decreased response to loss anticipation, along with a greater response to loss outcomes, suggests an altered ability to evaluate future risks and benefits based upon prior experience, which may underlie suboptimal decision-making in METH+ individuals that increases the likelihood of risky behavior.

Abstract
Teenagers commonly use cannabis. Expectancies related to the effects of cannabis play an important role in its consumption and are frequently measured with the Marijuana Effect Expectancies Questionnaire (MEEQ). This study aims to assess the psychometric properties (factor structure, internal consistency reliability, criterion validity) of the French MEEQ. A sample of 1,343 non-clinical teenagers (14–18 years) were recruited to answer a self-report questionnaire; 877 of them responded twice (one-year interval). A four-factor structure was obtained: Cognitive Impairment and Negative, Relaxation and Social Facilitation, Perceptual Enhancement and Craving and Negative Behavioral Effect Expectancies. It is concluded that the French MEEQ constitutes an appropriate tool to measure cannabis effect expectancies among adolescents.

Abstract
Cannabis is one of the most commonly drugs used by teenagers. Expectancies about its effects play a crucial role in cannabis consumption. Various tools have been used to assess expectancies, mainly self-report questionnaires measuring explicit expectancies, but implicit measures based on experimental tasks have also been developed, measuring implicit expectancies. The aim of this study was to simultaneously assess implicit/explicit expectancies related to cannabis among adolescent users and non-users. 130 teenagers attending school (55 girls) were enrolled (Age: M=16.40 years); 43.84% had never used cannabis ("non-users") and 56.16% had used cannabis ("users"). They completed self-report questionnaires evaluating cannabis use, cannabis-related problems, effect expectancies (explicit expectancies), alcohol use, social and trait anxiety, depression, as well as three Implicit Association Tests (IAT) assessing implicit expectancies. Adolescents manifested more implicit affective associations (relaxation, excitation, negative) than neutral ones regarding cannabis. These were not related to explicit expectancies. Cannabis users reported more implicit relaxation expectancies and less negative explicit expectancies than non-users. The frequency of use and related problems were positively associated with the explicit expectancies regarding relaxation and enhancement, and were negatively associated with negative explicit expectancies and negative implicit expectancies. Findings indicate that implicit and explicit expectancies play different roles in cannabis use by adolescents. The implications for experimentation and prevention are discussed.

Abstract
The Current Opioid Misuse Measure (COMM) has demonstrated promising psychometric properties among pain clinic and primary care patients. Given the high prevalence of the nonmedical use of prescription opioids among substance use disorder patients, the COMM may also be useful in substance use disorder treatment settings. The purpose of this study was to assess the factor structure and validity of the COMM in a sample of substance use disorder patients. Participants (n = 351) were recruited from a large residential substance use disorder treatment center and completed the COMM and several questionnaires assessing various substance use and health functioning characteristics. Factor analyses yielded a two-factor solution; however, each of the items in the second factor cross-loaded onto the first factor and just one factor was retained. To provide support for this new 11-item COMM, we found that higher scores on this COMM were associated with greater drug use severity, greater endorsement of positive, negative, and pain relief outcome expectancies related to opioid use, increased pain intensity, and decreased physical and mental health functioning. These findings provide initial support for the psychometric properties of this version of the COMM adapted for substance use disorder treatment settings. Given its promising psychometric properties, the 11 items of the COMM to evaluate the nonmedical use of prescription opioids have potential utility among substance use disorder patients. The COMM could be used to examine nonmedical use over the course of treatment and to aid treatment planning. It could also be used in research as an outcome measure.

Abstract
This study identified protective and risk factors of cannabis use initiation, including expectancies and social anxiety. A questionnaire was completed twice by 877 teenagers. Logistic regressions, mediation and moderation analyses were performed. Significant risk factors were alcohol use, peer users, perceptual enhancement, and craving expectancies. Protective factors were negative behavior expectancies and social anxiety. Social anxiety protected from initiation through the mediating role of perceptual enhancement and craving expectancies, whatever the role of peer users and alcohol use. Findings are discussed in terms of risk and protection, in an overall approach including internalizing factors. Results support the identification of an internalizing profile of adolescents for prevention or treatment and the importance of social anxiety and expectancies in intervention.

Abstract
OBJECTIVES The current study examined the cross-sectional associations between depressive symptoms and cannabis use, and the mediating role of positive and negative expectancies of cannabis use. METHODS Participants (n = 100) were cannabis-dependent veterans recruited as part of a larger self-guided cannabis quit study. Baseline (prequit) data were used. Depressive symptoms were assessed using the General Depression subscale of the Inventory of Depression and Anxiety Symptoms (IDAS), and cannabis use expectancies were assessed using the Marijuana Effect Expectancies Questionnaire. Quantity of cannabis use in the past 90 days was assessed with the Timeline Follow-Back. RESULTS A parallel multiple mediation path analysis was conducted to simultaneously examine the effects of positive and negative expectancies as mediators of the relation between IDAS-Depression and prequit cannabis use. Results indicated that depressive symptoms were indirectly related to cannabis use through positive, but not negative, expectancies. This effect was unique to IDAS-Dysphoria symptoms. CONCLUSIONS Depressive symptoms, particularly cognitive-affective symptom features, may be important to consider in better understanding positive cannabis effect expectancies among veterans in regard to cannabis use.

Abstract
RATIONALE Stress has been shown to be a significant factor in the maintenance of marijuana use. Oxytocin is a hypothalamic neuropeptide that has been shown to moderate behavioral responding to stress as well as play a role in the neuroadaptations that occur as a consequence of long-term drug use. OBJECTIVES The current study evaluated the impact of oxytocin pretreatment on craving, stress, and anxiety responses following a psychosocial stress task in marijuana-dependent individuals. METHODS In a laboratory setting, baseline measurements of craving (assessed using the Marijuana Craving Questionnaire; MCQ), salivary cortisol and dehydroepiandrosterone (DHEA), stress, and anxiety were collected in 16 participants (age 19-40) meeting DSM-IV criteria for marijuana dependence. Participants were then administered either oxytocin 40 IU (n = 8) or placebo (n = 8) nasal spray prior to completion of the Trier Social Stress Task (TSST). Measurements were repeated pre-TSST, immediately post-TSST, and 5-, 35-, and 60-min post-TSST. RESULTS Oxytocin reduced both MCQ total score and DHEA levels from before to after the TSST. It also decreased anxiety, but not subjective stress ratings. CONCLUSIONS Although preliminary, these results suggest that oxytocin may play a role in the amelioration of stress-induced reactivity and craving in marijuana-dependent individuals.

Abstract
Given that marijuana remains the most commonly used illicit substance, identification of the role of potentially malleable cognitive factors in marijuana-related behaviors remains an important goal. The Marijuana Effect Expectancies Questionnaire (MEEQ; Schafer & Brown, 1991) assesses marijuana effect expectancies that are differentially related to marijuana use and use-related problems. Evaluation of the desirability of marijuana effect expectancies may provide additional information regarding cognitions related to marijuana use behaviors. The present study examined the psychometric properties of the Marijuana Effect Expectancy Questionnaire-Valuations Scale (MEEQ-V) which was developed for this study to assess the desirability of marijuana effect expectancies. The sample was comprised of 925 (73.0% female) undergraduate participants, 41.9% of whom endorsed lifetime marijuana use and 24.7% of whom reported current (past three-month) use. The MEEQ-V scales demonstrated adequate internal consistency. Most (but not all) MEEQ-V scales were correlated with their corresponding MEEQ scale. There was some support for convergent validity. MEEQ-V scales were differentially related to frequency of marijuana use and use-related problems. Most MEEQ-V scales were related to frequency of marijuana use above and beyond variance attributable to corresponding MEEQ scales. Results suggest that assessment of desirability of marijuana's effects could provide unique and important information about cognitions related to marijuana use behaviors.

Abstract
BACKGROUND The current study tested the hypothesis that tension reduction expectancies mediate the relationship between anxiety symptoms and marijuana use. METHODS Interview data for 332 young adult females from Southern New England were collected from 2004 to 2009. RESULTS In structural equation modeling, anxiety symptoms had a significant direct effect (b(yx) = 0.227, 95% confidence interval [CI] 0.086-0.369, p < 0.05) on tension reduction expectancies and a significant indirect effect (b(yx) = 0.026, 95% CI 0.010-0.046, p < 0.05) on marijuana use. CONCLUSIONS The effect of anxiety symptoms on marijuana use was fully mediated by tension reduction expectancies. Implications for tension reduction as a possible component of treatment interventions are discussed.

Abstract
BACKGROUND Outcome expectancy is a central construct in models of addiction and relapse. Much expectancy research has been conducted in the context of alcohol; however, less is known about the structure of expectancies for marijuana and their associations with marijuana use outcomes. METHODS The data are taken from waves 3 and 4 of a longitudinal high-risk study of parents and adolescent offspring. Of those families who were retained at wave 3, 225 were high-risk and 205 were matched controls (low-risk). In the present study, we examine the factorial structure of marijuana expectancies (wave 3) in the offspring (using an instrument adapted from the alcohol literature) and test whether expectancies mediate the associations of familial risk for substance use, lifetime marijuana use in adolescence (wave 3) and current use in young adulthood (wave 4; reported approximately 5 years later). RESULTS We quantified four marijuana expectancy factors similar to those identified in previous studies when the offspring were adolescents (Mn age=15.2) and results of our mediation models suggest that negative marijuana expectancies (but not positive expectancies) together with lifetime adolescent marijuana use completely mediated the association between familial risk and current use of marijuana during young adulthood (Mn age=20.2). CONCLUSION Familial risk for current marijuana use in young adulthood appears to be transmitted through two orthogonal, prospective pathways. One pathway involves marijuana use during adolescence, and the second pathway involves reduced expectancies that using marijuana will result in cognitive and behavioral impairments.

Abstract
Women who experience recurrent intimate partner violence (IPV) may use alcohol or drugs because they expect that these substances will help them cope with the negative physical and psychological sequelae of IPV. However, expectancies for alcohol and drug use have not been explored among this population of women. We used the Relaxation and Tension-Reduction Scale, Arousal and Aggression Scale, and Social Assertion Scale of the Alcohol Expectancy Questionnaire and modified its items to assess both alcohol and drug expectancies of 212 community-based, IPV-exposed women. Results of bivariate correlations showed that greater alcohol and drug expectancies were significantly correlated with greater alcohol problems and greater posttraumatic stress total and symptom severity scores. Results of a multivariate regression model showed that after controlling for demographic characteristics and history of childhood trauma, Relaxation and Tension- Reduction expectancies were associated with number of days of alcohol use, alcohol problems, physical and sexual IPV severity scores, and posttraumatic stress total and reexperiencing symptom severity scores. Expectancies do not significantly moderate the relationships between IPV, posttraumatic stress, and problematic alcohol and drug use. Given the strong relationships of expectancies with IPV severity, posttraumatic stress, and alcohol problems, expectancies may serve as targets for interventions to reduce alcohol use and problems and improve health-related outcomes in IPV-exposed women.

Abstract
RATIONALE Cue-elicited craving and stress responses have been identified as predictors of relapse in drug dependence, but little research exists on the contribution of these factors to marijuana use specifically. OBJECTIVES The aims of the present study were to evaluate (1) responses to a psychological stressor, (2) responses to marijuana-related cues, and (3) if an exposure to a psychological stressor augmented craving subsequently elicited by marijuana-related cue exposure in marijuana-dependent individuals. METHODS Subjective (craving, stress), neuroendocrine (adrenocorticotropic hormone (ACTH), cortisol), and physiologic responses to the presentation of neutral and marijuana cues were assessed after randomization to a stress (Trier Social Stress Task (TSST)) or non-stress control condition in marijuana-dependent individuals. Outcome measures were assessed at baseline, post-stressor/pre-neutral cue, post-neutral cue, and post-marijuana cue. RESULTS Eighty-seven participants completed procedures (stress group, n = 45; non-stress group, n = 42). The stress group had a significant increase over the non-stress group in stress rating (p < 0.001), craving (p = 0.028), cortisol (p < 0.001), and ACTH (p < 0.001) after the completion of the TSST. An increased craving response for all participants was seen following the presentation of the marijuana cues (p = 0.005). Following the TSST or non-stress condition, the non-stress group had an increase in craving to marijuana cues as compared to neutral cues (p = 0.002); an increase in craving was not observed in the stress group (p = 0.404). CONCLUSIONS Marijuana cue exposure and a social stressor increased craving in marijuana-dependent individuals. Completion of the TSST did not increase craving response to subsequent marijuana cue exposure.

Abstract
BACKGROUND Outcome expectancies are a key cognitive construct in the etiology, assessment and treatment of Substance Use Disorders. There is a research and clinical need for a cannabis expectancy measure validated in a clinical sample of cannabis users. METHOD The Cannabis Expectancy Questionnaire (CEQ) was subjected to exploratory (n=501, mean age 27.45, 78% male) and confirmatory (n=505, mean age 27.69, 78% male) factor analysis in two separate samples of cannabis users attending an outpatient cannabis treatment program. Weekly cannabis consumption was clinically assessed and patients completed the Severity of Dependence Scale-Cannabis (SDS-C) and the General Health Questionnaire (GHQ-28). RESULTS Two factors representing Negative Cannabis Expectancies and Positive Cannabis Expectancies were identified. These provided a robust statistical and conceptual fit for the data. Internal reliabilities were high. Negative expectancies were associated with greater dependence severity (as measured by the SDS) and positive expectancies with higher consumption. The interaction of positive and negative expectancies was consistently significantly associated with self-reported functioning across all four GHQ-28 scales (Somatic Concerns, Anxiety, Social Dysfunction and Depression). Specifically, within the context of high positive cannabis expectancy, higher negative expectancy was predictive of more impaired functioning. By contrast, within the context of low positive cannabis expectancy, higher negative expectancy was predictive of better functioning. CONCLUSIONS The CEQ is the first cannabis expectancy measure to be validated in a sample of cannabis users in treatment. Negative and positive cannabis expectancy domains were uniquely associated with consumption, dependence severity and self-reported mental health functioning.

Abstract
BACKGROUND The U.S. prevalence of misuse of prescription opioid analgesics has increased substantially over the past decade but research on the factors influencing misuse of these medications remains preliminary. In the literature on alcohol, marijuana and stimulants, substance-related expectancies have been found to predict level of substance use. A similar line of research is needed to better understand reasons for misusing pain medications. METHODS This study utilized a sample of adults presenting to a large residential addictions treatment program (N=351). Participants were administered a new instrument, the Pain Medication Expectancy Questionnaire (PMEQ) as well as questions about current alcohol, illegal drug and pain medication misuse. Exploratory factor analysis was used to determine underlying factors of the PMEQ. RESULTS Results of the factor analysis supported a three-factor solution focusing on pleasure/social enhancement, pain reduction and negative experience reduction. In general, greater perceived expectancy of the positive effects of Prescription Opiate Analgesics (POAs) in all three domains were correlated with greater frequency of substance use and poorer mental health functioning. Expectancies directly related to the pain-reducing properties of POAs were also related to greater pain and poorer physical functioning. CONCLUSIONS This new measure of pain medication expectancies had sound psychometric properties and the resulting factors were associated with other clinically important aspects of patient functioning. The results highlight the need to assess for and address perceptions related to pain medication use in patients presenting to addictions treatment.

Abstract
Chronic marijuana (MRJ) use is associated with altered cognition and mood state, altered brain metabolites, and functional and structural brain changes. The objective of this study was to apply proton magnetic resonance spectroscopic imaging (MRSI) to compare proton metabolite levels in 15 young men with MRJ dependence and 11 healthy non-using (NU) young men. Spectra were acquired at 4.0 Tesla using 2D J-resolved MRSI to resolve coupled resonances in J-space and to quantify the entire J-coupled spectral surface of metabolites from voxels containing basal ganglia and thalamus, temporal and parietal lobes, and occipital white and gray matter. This method permitted investigation of high-quality spectra for regression analyses to examine metabolites relative to tissue type. Distribution of myo-inositol (mI)/creatine (Cr) was altered in the MRJ group whereas the NU group exhibited higher mI/Cr in WM than GM, this pattern was not observed in MRJ subjects. Significant relationships observed between global mI/Cr and distribution in WM, and self-reported impulsivity and mood symptoms were also unique between MRJ and NU groups. These preliminary findings suggest that mI, and distribution of this glial metabolite in WM, is altered by MRJ use and is associated with behavioral and affective features reported by young MRJ-dependent men.

Abstract
Human studies and animal experiments present a complex and often contradictory picture of the acute impact of marijuana on emotions. The few human studies specifically examining changes in negative affect find either increases or reductions following delta-9-tetrahydrocannabinol (THC) administration. In a 2 × 2, instructional set (told THC vs. told no THC) by drug administration (smoked marijuana with 2.8% THC vs. placebo) between-subjects design, we examined the pharmacologic effect of marijuana on physiological and subjective stimulation, subjective intoxication, and self-reported negative and positive affect with 114 weekly marijuana smokers. Individuals were first tested under a baseline/no smoking condition and again under experimental condition. Relative to placebo, THC significantly increased arousal and confusion/bewilderment. However, the direction of effect on anxiety varied depending on instructional set: Anxiety increased after THC for those told placebo but decreased among other participants. Furthermore, marijuana users who expected more impairment from marijuana displayed more anxiety after smoking active marijuana, whereas those who did not expect the impairment became less anxious after marijuana. Both pharmacologic and stimulus expectancy main effects significantly increased positive affect. Frequent marijuana users were less anxious after smoking as compared to less frequent smokers. These findings show that expectancy instructions and pharmacology play independent roles in effects of marijuana on negative affect. Further studies examining how other individual difference factors impact marijuana's effects on mood are needed.

Abstract
This study examined associations between the endorsement of drug use expectancies and the frequency and severity of marijuana use in a community sample of 332 women aged 18-24years who were not explicitly seeking treatment for their marijuana use. Participants were enrolled in a larger intervention study of motivational interviewing for various health behaviors and provided self-reports of their current and past marijuana use, marijuana abuse/dependence symptoms, and marijuana use expectancies. Marijuana use expectancies were measured using the six subscales of the Marijuana Effects Expectancy Questionnaire (MEEQ). Use frequency was defined as the number of use days in the past month, severity as the total number of DSM-IV marijuana abuse or dependence symptom criteria met. Replicating and extending prior research, expectations regarding Relaxation and Tension Reduction emerged as a robust belief in this cohort, predicting not only frequency (p<.01) but also severity (p<.01) of marijuana use in multivariate analyses. Severity of marijuana use was further predicted by expectations regarding loss of control, affective changes following marijuana use, and other aspects of emotion dysregulation (Global Negative Effects, p<.01). These findings document meaningful associations between substance-related cognitions and use behavior and suggest that marijuana users who hold certain beliefs regarding marijuana use may be particularly susceptible to clinically significant problems associated with their substance use. As such, marijuana use expectancies may represent a clinical target that could be incorporated into future interventions.

Abstract
BACKGROUND Individuals with social anxiety disorder (SAD) appear particularly vulnerable to marijuana-related problems. Yet, mechanisms underlying this association are unclear. METHODS This study examined the role of marijuana effect expectancies in the relation between SAD and marijuana problems among 107 marijuana users (43.0% female), 26.2% of whom met Diagnostic and Statistical Manual for Mental Disorders-Fourth Edition criteria for SAD. Anxiety and mood disorders were determined during clinical interviews using the Anxiety Disorders Interview Schedule-IV-L (ADIS-IV). RESULTS Analyses (including sex, marijuana use frequency, major depressive disorder, and other anxiety disorders) suggest that SAD was the only disorder significantly associated with past 3-month marijuana problems. Compared to those without SAD, individuals with SAD were more likely to endorse the following marijuana expectancies: cognitive/behavioral impairment and global negative expectancies. Importantly, these expectancies mediated the relations between SAD status and marijuana problems. CONCLUSIONS These data support the contention that SAD is uniquely related to marijuana problems and provide insight into mechanisms underlying this vulnerability.

Abstract
High social anxiety is related to marijuana problems, yet the nature of this relation remains unclear. We examined relations between marijuana effect expectancies, social anxiety, and marijuana among undergraduates (N=337). Social anxiety was related positively to Negative Expectancies and negatively to Tension Reduction Expectancies. Among socially anxious individuals, greater belief that marijuana produces Cognitive and Behavioral Impairment was associated with greater marijuana use rates. Negative Expectancies mediated the social anxiety-marijuana problems link. These data provide new insight into problematic marijuana use among this high-risk group.

Abstract
In order to better compare affect-related expectancies for tobacco and marijuana smoking, associations of marijuana and tobacco exposure to negative affect reduction (NAR), positive affect enhancement (PAE), and related smoking outcome expectancies were assessed in young individuals who reported smoking both marijuana and tobacco on a regular basis (dual users). More frequent smoking of a given substance was associated with expectations of greater NAR and PAE by that substance while duration of exposure did not reliably predict NAR or PAE drug expectancies. Contrary to expectations, individuals anticipating greater NAR and/or PAE for one substance did not exhibit corresponding expectancies for the other drug. These findings suggest that exposure duration may be less important than current usage levels in influencing affect expectancies and that the affect-related expectancies for tobacco and marijuana are largely independent of each other.

Abstract
The purpose of this study was to evaluate a brief version of the Marijuana Effect Expectancy Questionnaire (MEEQ; Schafer & Brown, 1991). The original MEEQ was reduced to 6 items (MEEQ-B). Principal component analysis (PCA) was performed and two factors were identified (positive effects and negative effects) accounting for 52.3% of the variance. Internal consistencies (0.42 to 0.60) were slightly lower than those of the original MEEQ. The negative effect expectancy scale correlated with criterion variables that assess marijuana use (p ≤ .05). This measure is a helpful tool for clinicians to use when assessing youth expectancies. Replication across different samples of adjudicated youth is recommended.

Abstract
This study is focused on sexually-related expectancies for substance use among juvenile detainees. Over a 6 month period, 272 juveniles recruited from a short-term detention facility completed measures assessing sexually-related expectancies in relation to alcohol use and marijuana use as well as measures assessing their actual use of these substances. Repeated measures analyses of sexual risk expectancy measures indicated that the sample as a whole, and older respondents in particular, expected more sexual risk in relation to using alcohol than in relation to using marijuana. Repeated measures analyses of sexual enhancement expectancy measures indicated that African-American and younger respondents expected more sexual enhancement from using marijuana than from using alcohol. Logistic regression analyses indicated that expectancies for sexual enhancement from alcohol use, and expectancies for sexual enhancement from marijuana use, were respectively associated with the use of these substances in a recent sexual incident. Limitations of the study are discussed.

Abstract
A questionnaire investigating adolescents' opinions and experiences regarding marijuana use was administered to 163 adolescents and young adults (96 boys and 67 girls) aged 13 to 20 (mean age = 16.8, s.d. = 1.5). Items referred to marijuana and other substances' dangerousness, representations regarding the positive and negative consequences of marijuana use. Responses were compared according to marijuana use status (classified into never/occasional use, current regular use and past regular use). Results show that adolescents' opinions differ according to their experience with marijuana use. Current regular users evaluate marijuana as less dangerous, but alcohol and heroin as more dangerous in comparison with never/occasional and past users. Current and past users are more likely to define marijuana as a medical drug and a plant used in agriculture, and less likely to define it as an illegal drug. Current and past users evaluate marijuana use as a way to cope with stress, to relax to a greater extent than do never/occasional users do. The latter attribute more negative consequences to marijuana use such as diminished driving ability and school performance and a pathway to hard drugs.

Abstract
Outcome effect expectancies are considered a key determinant of behavior in social learning models of substance use. The present study reports the development and psychometric properties of the Cocaine Effects Questionnaire (CEQ-P), designed specifically for use with patients in treatment for substance abuse. Items generated from patients and treatment staff were Likert-rated for frequency by 178 patients in substance abuse intensive day treatment. Seven components were derived and reduced into a 33-item measure with good reliability. The components loaded on two higher order components: positive effects (five scales) and negative effects (two scales). The CEQ-P shows good construct and concurrent validity in comparison with measures of similar constructs and with cocaine use variables. Few gender or racial differences were significant. Greater pretreatment cocaine use was associated with expecting less frequent positive effects and more frequent social withdrawal, consistent with clinical reports of later stage cocaine use. Alternatively, greater urges to use correlated positively with expected positive effects, specifically with expecting enhanced well-being, pain reduction, and sexual enhancement from cocaine. Less cocaine use during the 3-months after intensive treatment was predicted by expecting more negative effects from cocaine pretreatment. The CEQ-P is likely to be useful for both clinical and research purposes. Treatment implications were discussed.

Abstract
Although there has been considerable research into the adverse effects of cannabis, less attention has been directed toward subjective effects that may be associated with ongoing cannabis use. Examination of self-reported cannabis effects is an important issue in understanding the widespread use of cannabis. While reviews have identified euphoria as a primary factor in maintaining cannabis use, relaxation is the effect reported most commonly in naturalistic studies of cannabis users, irrespective of the method used. Self-reported effects in 12 naturalistic and 18 laboratory studies were compared. Regardless of methodology there was considerable variation in the effects experienced. Variation has been reported in terms of opposite effects being experienced by different individuals, variation of effects by individuals within a single occasion and between occasions of use. Factors that might explain this variation are outlined. Limitations of the available literature and suggested directions for future research are discussed. [Green B, Kavanagh D, Young R.

Abstract
This study examined the validity of classifying substance abusers based on temperament and dependence severity, and expanded the scope of typology differences to proximal determinants of use (e.g., expectancies, motives). Patients were interviewed about substance use, depression, and family history of alcohol and drug abuse. Self-report instruments measuring temperament, expectancies, and motives were completed. Participants were 147 male veterans admitted to inpatient substance abuse treatment at a U.S. Department of Veterans Affairs medical center. Cluster analysis identified four types of users with two high substance problem severity and two low substance problem severity groups. Two, high problem severity, early onset groups differed only on the cluster variable of negative affectivity (NA), but showed differences on antisocial personality characteristics, hypochondriasis, and coping motives for alcohol. The two low problem severity groups were distinguished by age of onset and positive affectivity (PA). The late onset, low PA group had a higher incidence of depression, a greater tendency to use substances in solitary contexts, and lower enhancement motives for alcohol compared to the early onset, high PA cluster. The four-cluster solution yielded more distinctions on external criteria than the two-cluster solution. Such temperament variation within both high and low severity substance abusers may be important for treatment planning.

Abstract
Complex patterns of multiple substance use pose clinical and methodological challenges for substance abuse clinical trials research. To increase measurement precision and internal validity, the modal approach has been to target both treatment interventions and outcome assessment to a single class of abused substance. This strategy warrants reconsideration because it entails limitations in recruitment feasibility and generalization of study findings. This report reviews pros and cons of single versus multiple targeted drugs, suggests guidelines for choosing between these strategies and outlines methods for broadening the scope of substance abuse clinical trails to take abuse of multiple substances into account. We recommend that investigators consider moving away from a single drug focus in three ways. First, include systematic assessment of a wide range of psychoactive substance use throughout the trial and evaluate the impact of study treatments on use of all classes of drugs. Second, except where contraindicated, include patients who use and abuse multiple classes of substances even in trials evaluating treatment of a single targeted drug. Third, consider inclusion of polysubstance abusers or those who primarily abuse multiple classes of substances in the same clinical trial. Although many treatment efficacy questions can best be answered by single focus studies, we recommend that such designs be adopted only after less restrictive designs are first considered.
