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.     

Racial differences in the link between alcohol expectancies and adolescent drinking

IntroductionAlcohol expectancies are important determinants and predictors of adolescent alcohol use. Research with African Americans has shown that the endorsement of positive alcohol expectancies differs from that of Whites during childhood and predicts different alcohol outcomes during young adulthood. However, limited research has explored racial differences in the relationship between expectancy endorsement and alcohol use in school-aged adolescents. The current study examines the effect of White or African American race on the relationship between positive alcohol expectancies and alcohol use.MethodsParticipants were 104 adolescents ages 12–18 who identified as either non-Hispanic White or non-Hispanic African American. Participants completed self-report measures of alcohol consumption and positive social alcohol expectancies.ResultsPreliminary analyses revealed no racial differences in alcohol expectancies or consumption. However, race moderated the relationship between alcohol expectancies and alcohol use such that more positive expectancies predicted alcohol use among White youth, but not African American youth.ConclusionsThese results suggest that alcohol expectancies, which were thought to be important mediators of the relationship between social and personality factors and adolescent alcohol use may not be as impactful for African Americans. Future research should focus on identifying factors posing unique risk for alcohol consumption in this population.     

Short-term effects of a brief intervention to reduce alcohol use and sexual risk among homeless young adults: results from a randomized controlled trial

Background: Homeless young adults are more likely than their never-homeless counterparts to abuse alcohol and engage in risky sexual behaviors, yet no interventions to simultaneously reduce both these behaviors among this vulnerable population have been systematically designed and evaluated. We therefore developed a brief intervention (BI) to reduce both alcohol use and sexual risk behaviors among homeless young adults. The results of a randomized trial testing the BI against an education comparison (EC) are presented.

Method: Young adults (N?=?61; age 17–22 years) from an urban, Northeastern crisis shelter were randomly assigned to either the two-session, individual-level BI or a time-matched, two-session, individual-level EC. Generalized linear mixed models for repeated measures determined effects of treatment condition on outcomes.

Results: The BI significantly increased participant readiness to change alcohol use. However, it did not significantly decrease primary alcohol or HIV sexual risk outcomes, independently or relative to EC (all ps > 0.05). Participants in the EC reduced times engaged in unprotected sex between baseline and post-intervention to a significantly greater extent (p?Conclusions: Findings suggest that the BI was acceptable and successful in getting participants to consider changing their drinking. However, lack of change in alcohol and sexual behavior outcomes indicates the need for further research to determine how to translate readiness to change into actual behavioral change among homeless young adults.     

The Role of Mental Health and Substance Use in Homeless Adults’ Tobacco Use and Cessation Attempts

Objective: Although tobacco use is prevalent among adults experiencing homelessness, research deficits exist regarding the mental health, substance use, and demographic correlates of tobacco use behaviors in this population. This study examined whether correlates of tobacco use among housed adults identified by the Center for Disease Control (CDC) were significant correlates of tobacco use and cessation attempts among a sample of homeless adults. Methods: Participants (N?=?421) were adults experiencing homelessness entering permanent supportive housing programs in Los Angeles. Multivariate logistic regression determined associations of lifetime mental health diagnoses, recent substance use, demographic characteristics, and lifetime literal homelessness with daily tobacco use and cessation attempts. Results: Lifetime diagnoses of schizophrenia, posttraumatic stress disorder, depression, bipolar disorder, and illicit substance use were associated with increased odds of daily tobacco use. A lifetime diagnosis of depression was associated with an increased likelihood of a past 3-month tobacco cessation attempt, while illicit substance use was associated with a lower likelihood of a cessation attempt. Conclusions: Findings suggest that demographic and clinical characteristics associated with tobacco use differ among this sample of homeless adults and those identified by the CDC among housed adults. Mental health conditions and substance use appear to be the primary correlates of tobacco use among adults experiencing homelessness and may be critical in efforts aimed at improving cessation.     

Polysubstance Use,Social Anxiety,and Length of Treatment for Alcohol Use Disorders

Objective: The purpose of the present study was to examine the interactive effects of social anxiety and psychosocial factors (i.e., group attendance, polysubstance use) on substance use treatment for men with a primary diagnosis of alcohol use disorder. Social anxiety and alcohol use disorders often co-occur, but it is currently unclear how having high social anxiety might affect aspects of substance use treatment, such as group participation and length of stay. Methods: This study compared men with alcohol use disorder only versus those with alcohol plus other drug disorders in a residential treatment facility. Measures included demographics, self-reported social anxiety, self-reported drug history, attendance at treatment groups, and total number of days in treatment. Results: Of 128 participants, 39 (30.5%) used only alcohol, while 89 (69.5%) used alcohol and other substances. Hierarchical linear regression showed only one significant interaction with social anxiety and length of treatment: people who used alcohol only or alcohol in addition to other substances (p < .05). Simple effects analyses revealed a positive relationship between social anxiety and length of stay among men who used only alcohol, but not among men who used more than one substance. Conclusions: Currently, the distinction between those who use only alcohol and those who use other substances as well is not often examined in the literature. However, the present study shows that this assumption of homogeneity may be inaccurate, given the differential relationships that these groups may have with factors such as social anxiety.     

Risk/Protective Factors Associated with Substance Use Among Runaway/Homeless Youth Utilizing Emergency Shelter Services Nationwide

Abstract

Rates of alcohol, tobacco, and marijuana use among runaway/homeless youth are substantially higher than found among American high school students. To understand the risk and protective factors associated with substance use, this study (1) assessed cigarette, alcohol, and marijuana use among a national sample of runaway/homeless youth, (2) identified risk/protective factors associated with lifetime substance use, and (3) examined risk/protective factors associated with six month frequency of substance use. Unduplicated cases (n = 11,841) from the 1997 Runaway/Homeless Youth Management Information System (RHY MIS) were analyzed. Results showed that substance use levels are greater than previously reported for this population. Predictors of cigarette, alcohol, and marijuana use and frequency were predominately individual youth risk factors and demographics rather than family risk factors. Providers in emergency youth shelters are in a prime position to assess substance use behaviors, as well as the associated risk factors. Provision of appropriate screening and referral to other services is essential to meet the needs of these youth.     

Friends matter but so does their substance use: The impact of social networks on substance use,offending and wellbeing among young people attending specialist alcohol and drug treatment services

Abstract

Aims: The current study assesses the impact of youth drug treatment on substance use, offending and wellbeing in a sample of young people recruited from specialist youth alcohol and drug treatment. The paper examines the impact of treatment engagement on the size and substance use profile of the young person's social network and hypothesises that the best treatment outcomes are associated with maintaining the size of the young person's social network but changing its composition to reduce the representation of substance use in social networks. Methods: A cohort study of 112 young people (aged 16–21) engaged in specialist youth alcohol and drug treatment services in Victoria, Australia, were recruited at the beginning of treatment and re-interviewed six months later using a structured questionnaire. Findings: There were improvements in substance use, social functioning, mental health and life satisfaction from baseline to follow-up. While network size was associated with mental health and quality of life markers, only having a lower proportion of substance users in the social network was associated with lower substance use and offending at follow-up. Conclusions: Social networks are a key component of wellbeing in adolescence. This study suggests that through independent analysis of network size and network composition, both the size and the composition of social networks have an important role to play in developing interventions for adolescent substance users that will sustain behaviour changes achieved in specialist treatment.     

Validation of the Comprehensive Effects of Alcohol Questionnaire in Older Adults

Background: Alcohol expectancies have been established as an important construct in the prediction of alcohol use among younger adults, but there is little understanding about the perceived expected effects of consuming alcohol in older adults. Beliefs about the expected effects of alcohol may be quite different in older adults compared to young adults, which may also play a different role in their drinking behavior. In older cohorts there may be stigma may be associated with drinking and the nature of drinking experiences may differ to those of younger adults. Existing measures of expectancies are based on the perspectives of younger adults and therefore warrant validation in an older sample. Objectives: The aim of this study is to validate the comprehensive effects of alcohol questionnaire (CEOA) in a sample of older adults, and to investigate the relationships between alcohol expectancies, their evaluations and alcohol use. Methods: A sample of community dwelling older adults (N?=?473) completed self-report measures assessing drinking behavior and alcohol expectancies. Exploratory factor analysis, confirmatory factor analysis, and hierarchical multiple regressions were conducted. Results: The final model of the CEOA supported two global dimensions of positive and negative expectancies, and showed excellent goodness-of-fit and internal consistency. Male drinkers were more likely to endorse positive expectancies and favorable evaluations of positive and negative expectancies. Favorable evaluations of positive expectancies were the strongest predictors of drinking frequency and quantity. Conclusions/Importance: The results support for the empirical validity of a two-factor expectancy model consisting of a 10-item negative expectancy factor and a 10-item positive expectancy factor. This more concise version could offer a more acceptable and time efficient measure of expectancies and valuations for older adults. Furthermore, the study provides important findings for the role of evaluations in their prediction of alcohol use.     

Cohabitation,Marijuana Use,and Heavy Alcohol Use in Young Adulthood

Background: Research on the association between cohabitation and substance use has been inconsistent, with some studies indicating an elevated risk among cohabiters and others finding either no difference in risk or a reduced risk of substance use. However, studies of this association have not utilized a causal modeling empirical framework. Objectives: The purpose of this research was to assess whether cohabitation has a causal effect on two forms of substance use among young adults: marijuana and heavy alcohol use. Methods: Three waves of data from the National Survey of Youth and Religion (n = 2,202; 2002–2008), a representative sample of young adults in the United States, and an augmented inverse probability weighting (AIPW) model designed for multivalued treatment effects estimation, were used to assess the association between cohabitation and substance use. Results: The findings indicated that cohabitation was associated with more frequent marijuana use only among females. Much of the effect of cohabitation, though, was due to previous factors, including substance use, that affected whether young adults cohabit or not. Moreover, there was no evidence that cohabitation had a causal impact on heavy alcohol use. Conclusions/Importance: There is little evidence that cohabitation has a causal impact on substance use in general. However, among young women, those who cohabited reported higher levels of marijuana use than those who remained single. Future research should address why this group is at particular risk of substance use.     

Social influence,health variables and criminal behaviours associated with substance use among rural Norwegian adolescents

Aims: To investigate social influence, health, criminality and substance use in a sample of 1288 Norwegian rural adolescents. Relations between these factors and substance use were examined.

Methods: Data were obtained from the ‘UngData’ study. A cross-sectional questionnaire survey was conducted among adolescents (n?=?740) in nine secondary schools and among 548 adolescents in three high schools across two counties. The response rate was 63%.

Findings: Deviant behaviours had higher social status among males and adolescents in high school. The social status of deviant behaviours and participation in criminal activities were associated with alcohol and illicit substance use. Parent–adolescent trust was positively associated with alcohol use and parent involvement with friends was similarly related to illicit substance use. The social status of physical appearance and talent in sports were negatively associated with alcohol use.

Conclusions: Early intervention could promote the social status of healthy activities and reduce the status of deviant behaviours. The transition between secondary school and high school may constitute a risk period for establishing problem behaviours and interventions should target this period. Research should test whether substance availability relates to differences in substance use in rural and urban settlements.     

Alcohol and Cigarette Use Among Warsaw Adolescents: Factors Associated With Risk and Resilience

Background: Youth in Poland are at notable risk for substance use. Guided by resiliency theory, we examine if developmental risk and promotive factors are associated with substance abuse risk. Objectives: We examined the association between adolescent cigarette and alcohol use and related risk and promotive factors including maternal support, neighbors' informal social control, friends' acceptance of substance use, and alcohol and cigarette use by nonparental adults. Method: Data were collected from a random sample of 13- to 14-year-old students attending Warsaw middle schools (N = 3029). We used hierarchical regression models and examined compensatory and protective models of resilience, controlling for sociodemograhic factors. Results: Our results indicated that friends' acceptance of substance use and perceived drug use among nonparental adults was associated with increased risk cigarette and alcohol use among youth. We found that maternal support moderated the relationship between friends' acceptance of substance use and cigarette use (protective model of resilience). Thus, mother support buffered the negative effects of friends' acceptance of substance use on youths' cigarette use. Neighbor's informal social control and maternal support were associated with reduced risk of alcohol use (compensatory model of resilience). Conclusion: Collectively, results of the study support compensatory and protective models of resilience in a large representative sample of Warsaw adolescents.     

Intoxication and binge and high-intensity drinking among US young adults in their mid-20s

ABSTRACT

Background: Alcohol use is a key risk factor for young adult mortality and disease, but limited research has focused on high-risk alcohol use among individuals moving from early young adulthood into building and maintaining an initial structure of adult life. This study estimated the prevalence of a range of alcohol use behaviors among US young adults aged 25/26, examined evidence for historical change in prevalence rates, and estimated associations between alcohol use and key demographic, substance use, and adult social role characteristics. Methods: Data were obtained from 3542 individuals selected for follow-up from the nationally representative 12th-grade student Monitoring the Future study. Respondents self-reported alcohol use behaviors at age 25/26 during calendar years 2005–2014. Results: Two fifths (39.9%) of young adults aged 25/26 reported being intoxicated at least once in the past 30 days; 25.6% reported usually experiencing a sustained high of 3 or more hours when drinking alcohol. Past-2-week binge drinking (5+ drinks in a row) was reported by 36.3% of respondents. Past-2-week high-intensity drinking (10+ drinks in a row) was reported by 12.4%. These age 25/26 alcohol use prevalence rates remained stable over the 10 years of data examined, in contrast to significant declines over historical time in alcohol prevalence rates among these same individuals at age 18. High-risk drinking was particularly associated with being male, white, unmarried, employed, a nonparent, and an alcohol user before finishing high school. Conclusions: Among US young adults in their mid-20s, alcohol use was highly normative and frequently included participation in high-risk drinking behaviors. High-risk alcohol use prevention approaches developed specifically to reach young adults in their mid-20s are needed, as well as efforts to increase proactive clinician screening to identify young adults participating in high-risk alcohol use.     

The Relation Between Moment-to-Moment Mindful Attention and Anxiety Among Young Adults in Substance Use Treatment

Background: A growing body of research has examined the intersection of mindfulness and substance use, and a large body of research has examined the relation between mindfulness and anxiety. Unfortunately, no research has been conducted on the relation between mindfulness and anxiety symptoms among young adults (i.e., 18–25 years old) in treatment for substance use. The purpose of the current study was to examine the relation between one facet of mindfulness, moment-to-moment attention, and anxiety (panic and generalized anxiety) among young adults in treatment for substance use. Methods: Preexisting patient records from a residential substance use treatment center for young adults were reviewed (N = 148). Patient records were examined from May 2012 to August 2013, which represented all young adult patients admitted to the residential treatment facility during this time. Results: Findings demonstrated that moment-to-moment mindful attention was associated with symptoms of panic disorder and generalized anxiety disorder even after controlling for gender, age, education, alcohol use, drug use, and the shared variance in generalized and panic symptoms. There were no gender differences in moment-to-moment mindful attention. Conclusions: These findings provide preliminary evidence that moment-to-moment mindful attention is associated with panic and generalized anxiety in young adults in substance use treatment. Combined with previous research on mindfulness-based interventions among adults in substance use treatment, research should examine the efficacy of mindfulness-based interventions for young adults in substance use treatment.     

Treatment Attendance Among Homeless Youth

Abstract

Treatment engagement and retention is a significant challenge for those who serve adolescent substance abusers. Homeless youth are considered especially challenging to engage and maintain in intervention efforts given their lack of residence and range of associated problems. This study examined predictors of treatment attendance and its impact on substance use outcome among a sample of substance abusing homeless youth (n = 133). Stepwise regression results indicated that a history of sexual abuse and suicide attempts were the two strongest predictors of the treatment attendance rate, higher attendance among those with these histories. Youths who attended greater than 6 treatment sessions showed a significant reduction in alcohol use at post-treatment, but attendance rates did not impact other substance use. Identifying predictors of treatment attendance among this subgroup of adolescents is vital given that much research suggests that treatment attendance alone is associated with better short and long term outcomes.     

Factors associated with substance use in older homeless adults: Results from the HOPE HOME study

Background: The median age of the single adult homeless population is 50 and rising. Although the prevalence of substance use decreases as individuals age, older adults now have a higher prevalence of substance use than older adults did 10 years ago. Homeless individuals have a higher prevalence of substance use disorders than the general population. However, little is known about substance use in older homeless adults. Methods: The objective of the study was to examine prevalence of and factors associated with substance use in a population-based sample (N = 350) of homeless individuals aged 50 and older in Oakland, California. Dependent variables included moderate or greater severity illicit drug symptoms (Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST) score >3) and moderate or greater alcohol symptoms (Alcohol Use Disorders Identification Test (AUDIT) score >7). Independent variables included demographics, mental health problems, and negative life course events such as physical and sexual abuse, school expulsion, and onset of homelessness. Results: Almost two thirds of participants, 64.6%, had moderate or greater severity symptoms for at least 1 illicit drug; 25.8% had moderate or greater severity alcohol symptoms. History of psychiatric hospitalization was associated with moderate or greater illicit drug symptoms (adjusted odds ratio [AOR] = 1.9, 1.0–3.6). The presence of major depressive symptoms was associated with moderate or greater severity alcohol symptoms (AOR = 1.8, 1.1–3.0). Conclusions: In this sample of older homeless adults, substance use is common. There is a need for substance use treatment programs, integrated with mental health services, which are targeted towards the needs of older homeless adults.     

E-Cigarette Outcome Expectancies among Nationally Representative Samples of Adolescents and Young Adults

Objectives: We conducted nationally representative surveys of adolescents and young adults to examine associations between e-cigarette outcome expectancies and e-cigarette use. Background: E-cigarette use among adolescents and young adults has grown rapidly in recent years, yet little research has examined the beliefs that may underlie this behavior among nationally representative samples. Methods: N?=?1,298 adolescents (13–17) and 2,219 young adults (18–25) were surveyed using a probability-based web panel. Participants completed a survey that included a new outcome expectancy measure examining 3 positive (enjoyment, social influences, advantage over cigarettes) and 2 negative (health concerns, smoker association) expectancy domains and ever having used e-cigarettes [ever use]. Results: Confirmatory factor analyses demonstrated a good fit of the outcome expectancies’ factor structure to the data. All outcome expectancies were associated with e-cigarette use in both populations in univariate analyses. In multiple logistic regression models controlling for several covariates, higher expected enjoyment was positively associated with a greater likelihood of e-cigarette use (aOR = 2.10, p < .05) among adolescents. Among young adults, enjoyment (aOR = 3.08, p < .001) was positively associated with a greater likelihood of use while both health concerns (aOR = 0.70, p < .01) and smoker association (aOR = 0.73, p < .05) were negatively associated with e-cigarette use. Conclusions: This study suggests that expected enjoyment is robustly associated with e-cigarette use among both adolescents and young adults. Health concerns may also play a role in e-cigarette use. Implications for e-cigarette prevention efforts and future research directions are discussed.     

The Drinking Expectancy Questionnaire for Men who have Sex with Men (DEQ-MSM): a measure of substance-related beliefs

Introduction and Aims. Alcohol expectancies are associated with drinking behaviour and post‐drinking use thoughts, feelings and behaviours. The expectancies held by specific cultural or sub‐cultural groups have rarely been investigated. This research maps expectancies specific to gay and other men who have sex with men (MSM) and their relationship with substance use. This study describes the specific development of a measure of such beliefs for alcohol, the Drinking Expectancy Questionnaire for Men who have Sex with Men (DEQ‐MSM). Design and Methods. Items selected through a focus group and interviews were piloted on 220 self‐identified gay or other MSM via an online questionnaire. Results. Factor analysis revealed three distinct substance reinforcement domains (‘Cognitive impairment’, ‘Sexual activity’ and ‘Social and emotional facilitation’). These factors were associated with consumption patterns of alcohol, and in a crucial test of discriminant validity were not associated with the consumption of cannabis or stimulants. Similarities and differences with existing measures will also be discussed. Discussion and Conclusions. The DEQ‐MSM represents a reliable and valid measure of outcome expectancies, related to alcohol use among MSM, and represents an important advance as no known existing alcohol expectancy measure, to date, has been developed and/or normed for use among this group. Future applications of the DEQ‐MSM in health promotion, clinical settings and research may contribute to reducing harm associated with alcohol use among MSM, including the development of alcohol use among young gay men.[Mullens AB, Young R McD, Dunne MP, Norton G.

Cigarette, marijuana, and alcohol use and prior drug treatment among newly homeless young adults in New York City: Relationship to a history of foster care

Background

This study examined whether a history of foster care was associated with the risk for substance use among newly homeless young adults, controlling for demographics and other risk factors.

Methods

Multiple logistic regression analyses, adjusted for controls, among consecutive admissions of 424 newly homeless young adults (18-21 years), determined the association between foster care and substance use.

Results

A history of foster care was reported by 35% of the sample. Alcohol, marijuana, and cigarettes were the most frequently used substances. After adjusting for demographics, childhood emotional, physical, and sexual abuse, prior arrest, unemployment, lack of high school diploma, and family drug use, homeless young adults with histories of foster care were: three times as likely to smoke cigarettes (AOR = 3.09); more than three times as likely to use marijuana (AOR = 3.30); and almost nine times as likely to have been in drug treatment (AOR = 8.81) than those without such histories.

Conclusions

It is important to screen homeless young adults who exited foster care for substance use, particularly cigarettes and marijuana. Risk reduction interventions should be targeted and tailored to their substance prevention needs.     

Patterns of alcohol use among men receiving treatment for heroin and/or cocaine use in England,Brazil and Spain. A cross-country analysis

Abstract

Introduction: Although alcohol is widely used concurrently with illicit drugs, the role of alcohol in recovery from and relapse to drug use is under-researched. This study investigates drinking patterns and factors associated with harmful drinking among men receiving community treatment for heroin and/or cocaine use.

Methods: Secondary analysis of 3 cross-sectional studies in England (n?=?153), Brazil (n?=?149) and Spain (n?=?131) was conducted. Sociodemographic, alcohol consumption (AUDIT), substance use, treatment characteristics, and physical health were assessed. Logistic regression determined factors associated with harmful drinking.

Results: 41% of men receiving heroin and/or cocaine treatment met criteria for harmful drinking. Of this, 28% were not receiving treatment for alcohol. Factors identified with harmful drinking among those who were not receiving treatment for alcohol use were as follows: homeless, unemployment/receiving benefits, poly drug use, history of injecting drug(s), hepatitis C seropositive, and receiving treatment for heroin use with/without treatment for cocaine use. Participants from England who met criteria for harmful drinking were more likely to report not receiving treatment for alcohol use than those from Brazil and Spain.

Discussion: Findings show that harmful drinking is common among men in treatment for drug use and remains neglected by the services.
