Advancing the Expectancy Concept via the Interplay Between Theory and Research

The Indirect Effects of Negative Affect Reduction Motives on the Relationship Between Sex and Severity of Problems When Trying to Quit Among Black Adults Who Smoke

BACKGROUND

African American/Black (hereafter referred to as Black) persons who smoke constitute a tobacco disparities group in the United States. Within the Black population, female smokers experience a disproportionate percentage of these disparities and are less likely to quit cigarettes than their male counterparts. Two factors implicated in female smokers' relatively worse quit success are (1) motives to smoke to reduce negative affect and (2) expectancies that smoking will reduce negative affect.

OBJECTIVES

The present study sought to test sex differences in these two clinically relevant cognitive constructs and evaluate the indirect effects of sex and severity of problems when trying to quit via smoking motives and expectancies for negative affect reduction among Black adults who smoke. Participants included 103 Black adults who smoke daily (72% male; Mage = 44.5 years, SD = 11.5 years).

RESULTS

Results revealed sex differences in both negative affect reduction motives and expectancies, as well as a partial indirect effect for sex on the severity of problems when trying to quit through negative affect reduction motives (a1b1 = 0.18, 95% CI [0.04, 0.38]) but not negative affect reduction expectancies (a2b2 = -0.01, 95% CI [-0.11, 0.09]) in a simultaneous model of indirect effects.

CONCLUSIONS

These findings shed light on the complex relationship between race, sex, and severity of problems when trying to quit, particularly when complicated by smoking motives and expectancies. Current data should be considered when developing sex-specific, tailored smoking cessation interventions for Black women.

Using Imagination to Integrate Contextual Effects in a Cue-Reactivity Paradigm in Patients with Alcohol Use Disorder: A Functional Magnetic Resonance Imaging Pilot Study

INTRODUCTION

In individuals with alcohol use disorder (AUD), the brain areas underlying cue-induced reactions (e.g., cingulum, striatum, thalamus) and altered activation of these regions have been identified by functional neuroimaging. Neuronal responses to a complex alcohol-related context are yet to investigate. To better understand contextual effects as well as the interplay of cue-induced neural reactions and context exposure, the present study implemented an imagination procedure during functional magnetic resonance imaging (fMRI).

METHODS

Thirteen patients with AUD and 13 healthy controls completed two rounds of a cue-reactivity paradigm inside an MRI scanner. Two individualized imagination tasks were conducted before each of the two cue reactivity tasks. A 2 (group) × 2 (imagination) × 2 (picture-type) analysis of variance (ANOVA) was performed.

RESULTS

The ANOVA revealed a main effect for imagination with higher activation in bilateral thalamus and right caudate nucleus and an interaction effect between imagination and group in right thalamus and left caudate nucleus, due to the patient group reacting stronger during alcohol-related imagination. These structures are involved in relaying sensory information and habit learning. No main or interaction effects of picture type were observed.

CONCLUSIONS

These results support the view that context effects alter the neural responses in thalamus and nucleus caudatus in patients with AUD, and that imagination tasks are suited to incorporate contextual influences in neurophysiological research designs. Future research needs to investigate whether the failure to observe a picture-type effect was due to limited statistical power and omission to individualize picture set, or whether an imagination procedure interferes with the evocation of picture-type effects.

Applying a Cognitive Neuroscience Perspective to Disruptive Behavior Disorders: Implications for Schools

A cognitive neuroscience perspective seeks to understand behavior, in this case disruptive behavior disorders (DBD), in terms of dysfunction in cognitive processes underpinned by neural processes. While this type of approach has clear implications for clinical mental health practice, it also has implications for school-based assessment and intervention with children and adolescents who have disruptive behavior and aggression. This review articulates a cognitive neuroscience account of DBD by discussing the neurocognitive dysfunction related to emotional empathy, threat sensitivity, reinforcement-based decision-making, and response inhibition. The potential implications for current and future classroom-based assessments and interventions for students with these deficits are discussed.

How Substance Users With ADHD Perceive the Relationship Between Substance Use and Emotional Functioning

OBJECTIVE

Although substance use (SU) is elevated in ADHD and both are associated with disrupted emotional functioning, little is known about how emotions and SU interact in ADHD. We used a mixed qualitative-quantitative approach to explore this relationship.

METHOD

Narrative comments were coded for 67 persistent (50 ADHD, 17 local normative comparison group [LNCG]) and 25 desistent (20 ADHD, 5 LNCG) substance users from the Multimodal Treatment Study of Children with ADHD (MTA) adult follow-up (21.7-26.7 years-old).

RESULTS

SU persisters perceived SU positively affects emotional states and positive emotional effects outweigh negative effects. No ADHD group effects emerged. Qualitative analysis identified perceptions that cannabis enhanced positive mood for ADHD and LNCG SU persisters, and improved negative mood and ADHD for ADHD SU persisters.

CONCLUSION

Perceptions about SU broadly and mood do not differentiate ADHD and non-ADHD SU persisters. However, perceptions that cannabis is therapeutic may inform ADHD-related risk for cannabis use.

Cognitive appraisals of alcohol use in early adolescence: Psychosocial predictors and reciprocal associations with alcohol use

Early adolescence is a dynamic period for the development of alcohol appraisals (expected outcomes of drinking and subjective evaluations of expected outcomes), yet the literature provides a limited understanding of psychosocial factors that shape these appraisals during this period. This study took a comprehensive view of alcohol appraisals and considered positive and negative alcohol outcome expectancies, as well as subjective evaluations of expected outcomes. Developmental-ecological theory guided examination of individual, peer, family, and neighborhood predictors of cognitive appraisals of alcohol and use. A community sample of 378 adolescents (mean age 11.5 years at Wave 1, 52% female) was assessed annually for 4 years. Longitudinal path analysis suggested that the most robust predictors of alcohol appraisals were peer norms. Furthermore, perceived likelihood of positive and negative alcohol outcomes prospectively predicted increases in drinking. There was limited support for appraisals operating as mediators of psychosocial risk and protective factors.

"I Use Weed for My ADHD": A Qualitative Analysis of Online Forum Discussions on Cannabis Use and ADHD

Background

Attention-deficit/hyperactivity disorder (ADHD) is a risk factor for problematic cannabis use. However, clinical and anecdotal evidence suggest an increasingly popular perception that cannabis is therapeutic for ADHD, including via online resources. Given that the Internet is increasingly utilized as a source of healthcare information and may influence perceptions, we conducted a qualitative analysis of online forum discussions, also referred to as threads, on the effects of cannabis on ADHD to systematically characterize the content patients and caregivers may encounter about ADHD and cannabis.

Methods

A total of 268 separate forum threads were identified. Twenty percent (20%) were randomly selected, which yielded 55 separate forum threads (mean number of individual posts per forum thread = 17.53) scored by three raters (Cohen’s kappa = 0.74). A final sample of 401 posts in these forum threads received at least one endorsement on predetermined topics following qualitative coding procedures.

Results

Twenty-five (25%) percent of individual posts indicated that cannabis is therapeutic for ADHD, as opposed to 8% that it is harmful, 5% that it is both therapeutic and harmful, and 2% that it has no effect on ADHD. This pattern was generally consistent when the year of each post was considered. The greater endorsement of therapeutic versus harmful effects of cannabis did not generalize to mood, other (non-ADHD) psychiatric conditions, or overall domains of daily life. Additional themes emerged (e.g., cannabis being considered sanctioned by healthcare providers).

Conclusions

Despite that there are no clinical recommendations or systematic research supporting the beneficial effects of cannabis use for ADHD, online discussions indicate that cannabis is considered therapeutic for ADHD—this is the first study to identify such a trend. This type of online information could shape ADHD patient and caregiver perceptions, and influence cannabis use and clinical care.

Drugs as instruments: a new framework for non-addictive psychoactive drug use

Most people who are regular consumers of psychoactive drugs are not drug addicts, nor will they ever become addicts. In neurobiological theories, non-addictive drug consumption is acknowledged only as a "necessary" prerequisite for addiction, but not as a stable and widespread behavior in its own right. This target article proposes a new neurobiological framework theory for non-addictive psychoactive drug consumption, introducing the concept of "drug instrumentalization." Psychoactive drugs are consumed for their effects on mental states. Humans are able to learn that mental states can be changed on purpose by drugs, in order to facilitate other, non-drug-related behaviors. We discuss specific "instrumentalization goals" and outline neurobiological mechanisms of how major classes of psychoactive drugs change mental states and serve non-drug-related behaviors. We argue that drug instrumentalization behavior may provide a functional adaptation to modern environments based on a historical selection for learning mechanisms that allow the dynamic modification of consummatory behavior. It is assumed that in order to effectively instrumentalize psychoactive drugs, the establishment of and retrieval from a drug memory is required. Here, we propose a new classification of different drug memory subtypes and discuss how they interact during drug instrumentalization learning and retrieval. Understanding the everyday utility and the learning mechanisms of non-addictive psychotropic drug use may help to prevent abuse and the transition to drug addiction in the future.

Acute Effects of Intoxication and Arousal on Approach/Avoidance Biases Toward Sexual Risk Stimuli in Heterosexual Men

This study tested the effects of alcohol intoxication and physiological arousal on cognitive biases toward erotic stimuli and condoms. Ninety-seven heterosexual men were randomized to 1 of 6 independent conditions in a 2 (high arousal or control) × 3 (alcohol target BAC = 0.08, placebo, or juice control) design and then completed a variant of the Approach-Avoidance Task (AAT). The AAT assessed reaction times toward approaching and avoiding erotic stimuli and condoms with a joystick. Consistent with hypotheses, the alcohol condition exhibited an approach bias toward erotic stimuli, whereas the control and placebo groups exhibited an approach bias toward condom stimuli. Similarly, the participants in the high arousal condition exhibited an approach bias toward erotic stimuli and the low arousal control condition exhibited an approach bias toward condoms. The results suggest that acute changes in intoxication and physiological arousal independently foster biased responding toward sexual stimuli and these biases are associated with sexual risk intentions.

ADHD and Marijuana-Use Expectancies in Young Adulthood

OBJECTIVE

This study examined mean level differences in marijuana expectancies and the differential associations between expectancies and marijuana use for individuals with and without a history of Attention-Deficit/Hyperactivity Disorder (ADHD).

BACKGROUND

Substance-use expectancies are a widely studied risk factor for alcohol and other drug use. The relations between marijuana-use expectancies and self-reported marijuana use have not been examined in young adults with ADHD, a population shown to be at risk for marijuana use.

METHOD

Participants were 306 (190 ADHD and 116 non-ADHD) young adults (M age = 20.06, SD = 2.03) from the Pittsburgh ADHD Longitudinal Study (PALS) who provided data about marijuana use and marijuana-use expectancies.

RESULTS

Individuals in the ADHD group reported lower levels of social enhancement, tension reduction, and cognitive and behavioral-impairment expectancies compared to individuals in the non-ADHD group. Positive and negative marijuana-use expectancies were associated with marijuana use frequency in the whole sample and statistically significant ADHD group by expectancy interactions were found. Sexual-enhancement expectancies were more strongly associated with marijuana use frequency among individuals with ADHD histories while cognitive behavioral-impairment expectancies were more strongly associated with marijuana use frequency among individuals without ADHD.

CONCLUSIONS

Marijuana-use expectancies may be acquired, and operate differently, for individuals with and without ADHD histories. Although future research is needed to test this speculation, these differences may be associated with ADHD-related difficulties in higher order cognitive processes that affect the encoding and utilization of expectations regarding marijuana's effects.

Uso de álcool e expectativas do beber entre universitários: uma análise das diferenças entre os sexos

O estudo analisou comparativamente o consumo de álcool e expectativas do beber de homens e mulheres, verificando a relação entre as variáveis. Contou-se com uma amostra de 238 universitários, que responderam aos instrumentos AUDIT e AEQ-A. Homens apresentaram prevalência significativamente maior de uso de álcool no ano, uso problemático e binge. Expectativas de transformações globais positivas e de melhora no desempenho sexual foram maiores entre os homens. Houve correlação positiva entre expectativas e a gravidade de problemas associados ao consumo de álcool para ambos os sexos, no entanto, essa relação foi significativa apenas para os homens. Resultados indicam que diferenças das expectativas do beber entre os sexos podem ter um importante papel em ações de prevenção mais precisas e eficazes sobre o uso de álcool de homens e mulheres.

Transitions into underage and problem drinking: developmental processes and mechanisms between 10 and 15 years of age

Numerous developmental changes occur across levels of personal organization (eg, changes related to puberty, brain and cognitive-affective structures and functions, and family and peer relationships) in the age period of 10 to 15 years. Furthermore, the onset and escalation of alcohol use commonly occur during this period. This article uses both animal and human studies to characterize these multilevel developmental changes. The timing of and variations in developmental changes are related to individual differences in alcohol use. It is proposed that this integrated developmental perspective serve as the foundation for subsequent efforts to prevent and to treat the causes, problems, and consequences of alcohol consumption.

The relative contribution of metacognitive beliefs and expectancies to drinking behaviour

AIM

Alcohol expectancies refer to the effects of alcohol use anticipated by an individual. Metacognitive beliefs about alcohol use are a specific form of alcohol expectancy relating to the beliefs individuals hold about the effects of alcohol on cognition and emotion.

METHOD

A community sample of 355 individuals completed measures of alcohol expectancies, metacognitive beliefs about alcohol use, and drinking behaviour.

RESULTS

Correlation analyses indicated that alcohol expectancies and metacognitive beliefs about alcohol use were positively correlated with drinking behaviour. Structural regression modelling revealed that three of the four facets of metacognitive beliefs about alcohol use were independent contributors to drinking behaviour, and that, when controlling for such beliefs, only negative social performance alcohol expectancies explained additional variance in drinking behaviour.

CONCLUSIONS

These results add to the argument that there is a value in differentiating between metacognitive beliefs about alcohol use and alcohol expectancies in predicting drinking behaviour.

Smoking expectancies for flavored and non-flavored cigarettes among college students

Several tobacco companies have introduced specially flavored cigarettes, yet little is known about their appeal among college student nonsmokers, regular smokers, and those susceptible to smoking. Undergraduates (N=424) rated 12 brands of cigarettes on multiple attributes based on manufacturer advertisements. This paper focused on two brands with flavored and non-flavored versions (Camel and Salem). Despite brand, regular smokers and those susceptible to smoking initiation had higher positive expectancies and lower negative expectancies about smoking than nonsmokers. Flavored cigarettes elicited higher positive expectancies than non-flavored counterparts across all groups, including nonsmokers. Indeed, the degree to which flavored Camels had higher positive expectancies than Camel Lights was at least as large in a group of susceptible nonsmokers and experimenters (susceptible/experimenters). Despite being present in nonsmokers and susceptible/experimenters, negative expectancies were significantly lower for flavored versus non-flavored brands. Logistic regressions revealed that positive expectancies predicted "intention to try" each brand for regular smokers and susceptible/experimenters. These findings suggest that targeting the marketing of positive attributes may be useful in preventing smoking behavior.

Predicting DUI recidivism: Personality, attitudinal, and behavioral risk factors

AIMS

To predict DUI recidivism using personality, attitudinal, and behavioral factors.

DESIGN

We conducted cross-sectional analyses of survey data. Covariance structure modeling was used to identify unique predictors of driving after drinking (DAD), alcohol consumption, and high-risk driving.

PARTICIPANTS

Two hundred and eighty individuals with multiple DUI convictions, predominately male and Hispanic. Participants were surveyed in the Rio Hondo Courthouse, Los Angeles County, California.

MEASUREMENTS

The survey included measures of past year frequency of DAD, socially desirable response bias, sensation seeking, trait hostility, high-risk driving style, alcohol expectancies, and alcohol consumption.

FINDINGS

DAD was positively related with frequency of drinking and with positive alcohol expectancies. It was negatively associated with socially desirable response bias. Measures of high-risk driving and the personality variables were highly negatively associated with socially desirable response bias.

CONCLUSIONS

Individuals who believe that they are affected positively by alcohol intoxication are not responding to the standard penalties for DUI and persist in driving after drinking. These beliefs may serve as an important point of intervention for programs designed to reduce drunk driving. The current research also suggests that self-report measures of DAD, as well as many hypothesized risk factors, are highly correlated with socially desirable response biases. Failure to control for such biases may be a significant threat to the validity of research in this field.

Unique contributions of meanings of smoking and outcome expectancies to understanding smoking initiation in middle school

BACKGROUND

Previous research has shown that meanings of smoking are highly predictive of smoking in middle school children. Three factors of meanings of smoking have been suggested in the literature: personal meanings, functional meanings, and social meanings. These conceptually derived factors of meanings of smoking have not previously been empirically studied.

PURPOSE

This study examined the factor structure of the Meanings of Smoking Index (MSI) to determine the unique contribution of meanings of smoking and positive outcome expectancies to smoking behavior in middle school children.

METHODS

A multiethnic sample of 2,247 eighth-grade students enrolled in 24 middle schools in greater Los Angeles completed a paper-and-pencil survey in class.

RESULTS

Four factors of the MSI emerged (functional, personal, social image, and weight concern). Positive outcome expectancies and each of the four factors of the MSI predicted lifetime smoking in a multivariate model.

CONCLUSIONS

Meanings of smoking were empirically distinct from positive outcome expectancies. Adolescents who endorsed personal and functional meanings were more likely to smoke. Social image and weight concern meanings were negatively related to smoking after controlling for all other meanings. Meanings of smoking may prove to be important and modifiable mediators of smoking and therefore useful in future prevention studies.

The relationship between social anxiety disorder and alcohol use disorders: A critical review

Epidemiological studies have demonstrated a significant co-morbidity between social anxiety disorder (SAD) and alcohol use disorders (AUDs). Despite the fact that many studies have demonstrated strong relationships between SAD and AUD diagnoses, there has been much inconsistency in demonstrating causality or even directionality of the relationship between social anxiety and alcohol-related variables. For example, some studies have showed a positive relationship between social anxiety and alcohol-related variables, while others have shown a negative relationship or no relationship whatsoever. In an attempt to better understand the relationship between social anxiety and alcohol, some researchers have explored potential moderating variables such as gender or alcohol expectancies. The present review reports on what has been found with regard to explaining the high co-morbidity between social anxiety and alcohol problems, in both clinical and non-clinical socially anxious individuals. With a better understanding of this complex relationship, treatment programs will be able to better target specific individuals for treatment and potentially improve the efficacy of the treatments currently available for individuals with co-morbid SAD and AUD.

Challenging implicit and explicit alcohol-related cognitions in young heavy drinkers

AIMS

To test whether an expectancy challenge (EC) changes implicit and explicit alcohol-related cognitions and binge drinking in young heavy drinkers. This is important for theoretical and practical reasons: the EC presents a critical test for the hypothesized mediational role of alcohol cognitions and the EC has been presented as a promising intervention to counter alcohol problems in heavy drinking youth. SETTING, PARTICIPANTS AND INTERVENTION: Ninety-two heavy drinking college and university students (half women) were assigned randomly to the EC or control condition (a sham alcohol experiment in the same bar-laboratory).

MEASUREMENTS

Explicit alcohol cognitions and alcohol use were assessed with paper-and-pencil measures. Alcohol use was assessed prior to the experiment and during a 1-month follow-up. Implicit alcohol-related cognitions were assessed with two versions of the Implicit Association Test (IAT), adapted to assess implicit valence and arousal associations with alcohol.

FINDINGS AND CONCLUSIONS

The EC resulted in decreased explicit positive arousal expectancies in men and women alike. There was some evidence for a differential reduction in implicit arousal associations, but findings depended on the version of the IAT and on the scoring-algorithm used. In men (but not in women) there was a short-lived differential reduction in prospective alcohol use (significant in week 3 of the follow-up), and this reduction was partially mediated by the decrease in explicit positive arousal expectancies. These findings suggest that an EC successfully changes explicit alcohol cognitions and that this may have short-lived beneficial effects in heavy drinking young men.

Development and validation of an adolescent smoking consequences questionnaire

Several researchers have investigated the role of outcome expectancies in the initiation and maintenance of smoking behavior. Empirical studies with adults, using a validated self-report instrument, have shown that smokers identify higher levels of positive smoking expectancies and lower levels of negative smoking expectancies compared with nonsmokers and ex-smokers. Studies examining smoking outcome expectancies among adolescents have yielded similar findings, but many of these studies did not use a self-report expectancy measure validated with teens. Therefore, the present study sought to modify a well-known adult smoking expectancy instrument, the Smoking Consequences Questionnaire (SCQ), and to validate its factor structure with a community sample of adolescent nonsmokers and current smokers (aged 11-19 years). Results of a confirmatory factor analysis provided support for a seven-latent-factor structure modeled after the SCQ-Adult. As expected, smoking behavior and the intent to smoke in the future were associated with the endorsement of positive and negative smoking outcome expectancies. The psychometric data provide early support for the validity and reliability of this modified SCQ, renamed the Adolescent Smoking Consequences Questionnaire, for the assessment of smoking expectancies among smoking inexperienced and experienced teens.

Social anxiety and alcohol use: evaluation of the moderating and mediating effects of alcohol expectancies

Previous work suggests that social anxiety is inconsistently related to alcohol use. To further explore this relationship, alcohol outcome expectancies were evaluated as potential moderator and mediators in a large sample (N=284) of college undergraduates. The expectancy variables included positive and negative alcohol outcome expectancies as well as expectancies specific to social facilitation. Consistent with a self-presentation model of shyness, social anxiety was related to decreased drinking. Interestingly, social anxiety was associated with increased positive as well as increased negative expectancies. There was not support for moderator or mediator effects. Consistent with prior work, social facilitation expectancies appear to operate as a suppressor variable in the relationship between social anxiety and alcohol use.

Changing expectancies: cognitive mechanisms and context effects

This article presents the proceedings of a symposium at the 2002 RSA Meeting in San Francisco, organized by Reinout W. Wiers and Mark D. Wood. The symposium combined two topics of recent interest in studies of alcohol expectancies: cognitive mechanisms in expectancy challenge studies, and context-related changes of expectancies. With increasing recognition of the substantial role played by alcohol expectancies in drinking, investigators have begun to develop and evaluate expectancy challenge procedures as a potentially promising new prevention strategy. The two major issues addressed in the symposium were whether expectancy challenges result in changes in expectancies that mediate intervention (outcome relations), and the influence of simulated bar environments ("bar labs," in which challenges are usually done) on expectancies. The presentations were (1) An introduction, by Jack Darkes; (2) Investigating the utility of alcohol expectancy challenge with heavy drinking college students, by Mark D. Wood; (3) Effects of an expectancy challenge on implicit and explicit expectancies and drinking, by Reinout W. Wiers; (4) Effects of graphic feedback and simulated bar assessments on alcohol expectancies and consumption, by William R. Corbin; (5) Implicit alcohol associations and context, by Barry T Jones; and (6) A discussion by Kenneth J. Sher, who pointed out that it is important not only to study changes of expectancies in the paradigm of an expectancy challenge but also to consider the role of changing expectancies in natural development and in treatments not explicitly aimed at changing expectancies.
