RESUMO

BACKGROUND: Negative affect and low distress tolerance have been associated with increased likelihood of alcohol consumption and relapse. This study utilized the Paced Auditory Serial Attention Test - Computerized Version (PASAT-C) to examine affective reactivity, cognitive performance, and distress tolerance during early abstinence among heavy drinking adolescents. METHODS: Participants, ages 16 to 18 (50% female), were 23 heavy episodic drinking youth (HED) and 23 demographically matched, nondrinking teens (CON). Both groups were drawn from the same schools and assessed at 3 time points: HED was first studied within 10 days (M = 4.26, SD = 4.4) of heavy episodic drinking and then at two 2-week intervals over 4 subsequent weeks of abstinence from alcohol and drugs. CON were studied at the same 2-week intervals. RESULTS: From the findings, it was observed that HED responded with greater emotional response to the PASAT-C (i.e., greater increases in frustration and irritability and greater decreases in happiness) at the initial assessment, but their affective responses diminished with sustained abstinence. CON and HED task performance did not differ at the initial assessment or across time. HED showed faster task discontinuation times to the PASAT-C at the first assessment, and both groups reduced task persistence across testings. Among HED, greater lifetime and recent alcohol consumption, alcohol-induced blackouts, and withdrawal symptoms were associated with increases in negative affect with PASAT-C exposure. Earlier age of onset of alcohol use was linked to poorer performance. CONCLUSIONS: Heavy episodic drinking adolescents demonstrated heightened emotional reactivity and poorer distress tolerance to a cognitively challenging task during early abstinence. The combination of elevated negative affect and low distress tolerance may place adolescents at a heightened risk of escalations in or return to alcohol involvement.

RESUMO

The present study investigated the rate and pattern of neuropsychological recovery in heavy episodic drinking teens during the initial days to weeks of abstinence from alcohol. Adolescents (ages, 16-18 years) with histories of heavy episodic drinking (HED; N = 39) and socio-demographically similar control teens (CON; N = 26) were recruited from San Diego area schools. HED and CON were comparable on 5th grade standardized math and language arts test performance to ensure similar functioning before onset of substance use. Participants were administered three neuropsychological test batteries with 2-week intervals during a 4-week monitored abstinence period. HED teens performed worse overall than CON on tests of prospective memory (p = .005), cognitive switching (p = .039), inhibition task accuracy (p = .001), verbal memory (p's < .045), visuospatial construction (p's < .043), and language and achievement (p's < .008). The statistically significant group × time interaction for block design demonstrated normalization within the 4 weeks of abstinence for the HED (p = .009). This study identified cognitive performance deficits associated with heavy episodic drinking in adolescence during early abstinence and with sustained 4-week abstention. These findings suggest alcohol-related influences on several underlying brain systems that may predate the onset of alcohol abuse or dependence or take longer than 4 weeks to recover.

RESUMO

BACKGROUND: While it is clear that affect is negatively impacted by heavy drinking in adulthood and that it improves with abstinence, little is known about effects of heavy drinking on mood during adolescence. METHODS: This study examined negative mood states among 2 groups of 16- to 18-year-old high school students; youth with a history of recent heavy episodic drinking (HED; n = 39) and comparison youth with limited lifetime drinking experience (CON; n = 26). Affect was assessed at 3 time points during a 4- to 6-week period of monitored abstinence using the Hamilton Rating Scales for Anxiety and Depression; self-reports were obtained with the state portion of the State-Trait Anxiety Inventory, and experience sampling of current affect was assessed via daily text messages sent at randomly determined times in the morning, afternoon, and evening. RESULTS: Youth with a recent history of HED reported more negative affect compared with nondrinking youth during early stages of abstinence (days since last HED at assessment 1: M = 6.46; SD = 5.06); however, differences in affect were not observed after 4 to 6 weeks of abstinence. Sex differences were evident, with HED girls reporting greater depression and anxiety than HED male peers. Although not significant, response patterns indicated that boys may experience faster resolution of negative emotional states than girls with sustained abstinence. CONCLUSIONS: Findings suggest that high-dose drinking is associated with elevated negative affect for adolescents and that negative mood states may take longer to resolve for girls than for boys following heavy drinking episodes. Future research clarifying naturally occurring changes in affective response during early and sustained abstinence is necessary for improving programs designed to promote adolescent decision-making and to reduce risk for relapse.

RESUMO

Drug courts and mental health courts have expanded rapidly in the past several decades to provide more efficient coordination of treatment and supervision of offenders with behavioral health problems. A significant number of offenders in these court-based programs have co-occurring mental and substance use disorders, which predict early termination, relapse, rearrest, and other negative outcomes. A web-based national survey examined programmatic adaptations for co-occurring disorders (CODs) among 54 drug courts, mental health courts, and freestanding COD dockets. COD dockets were smaller and of longer duration, and provided more intensive services than programs situated in drug courts or in mental health courts. However, more similarities than differences were noted across the different types of court-based program. Key adaptations for CODs included extended program duration, highly intensive and integrated treatment, smaller, less formal, and more frequent hearings, and use of specialized supervision teams and dually credentialed staff.

RESUMO

BACKGROUND: Binge drinking is common among adolescents. Alcohol use, particularly binge drinking, has been associated with neurocognitive deficits and increased risk-taking behaviors, which may contribute to negative driving outcomes among adolescents even while sober. OBJECTIVES: To examine potential differences in self-reported risky driving behaviors between adolescent binge drinkers and a matched sample of controls on measures of (1) compliance with graduated licensing laws, (2) high-risk driving behaviors, and (3) driving outcomes (i.e., crashes, traffic tickets). METHODS: This study examined driving behaviors and outcomes in adolescent recent binge drinkers (n = 21) and demographically and driving history matched controls (n = 17) between the ages of 16-18 years. RESULTS: Binge drinkers more frequently violated graduated licensing laws (e.g., driving late at night) and engaged in more "high-risk" driving behaviors, such as speeding and using a cell phone while driving. Binge drinkers had more traffic tickets, crashes, and "near crashes" than the control group. Speeding was the behavior most associated with crashes within the binge drinkers. CONCLUSION: In this study, binge-drinking teens consistently engage in more dangerous driving behaviors and experience more frequent crashes and traffic tickets. They are also less compliant with preventative restrictions placed on youth while they are learning critical safe driving skills. SCIENTIFIC SIGNIFICANCE: These findings highlight a need to examine the contribution of underlying traits (such as sensation seeking) and binge-related cognitive changes to these high-risk driving behaviors, which may assist researchers in establishing alternative prevention and policy efforts targeting this population.

RESUMO

Children's alcohol expectancies shift in late childhood/early adolescence in ways thought to lead to increased risk for adolescent alcohol use. The precise nature of this shift and the maturational processes that may influence it remain to be clarified. To these ends, we compared expectancy endorsement by grade across four expectancy domains: positive, negative, arousal, and sedation, in a cross-sectional sample of 3rd-6th grade children attending afterschool programs (n = 299). Structural equation modeling (SEM) was then used to describe the relationships between expectancies and differences in (a) cognitive ability and concept formation, (b) risk-taking personality traits, and (c) social exposure or values regarding alcohol-related information. Results showed those children in higher grades endorsed significantly more positive, negative, and sedating expectancies for alcohol than their younger peers. Concept formation partially and fully mediated the relationships between grade and both positive and sedating expectancies, respectively, but not the relationship between grade and negative expectancies. Sensation seeking did not increase across grades in this sample, and the relationship between sensation seeking and positive expectancies was fully mediated by reported alcohol exposure and values. This study provides a basis for future exploration of developmental influences on alcohol expectancies, an understanding of which may be helpful in the design of prevention efforts targeting high-risk youth before adolescence.

RESUMO

Alcohol-related cognitions, particularly expectancies for drinking and nondrinking and motives for nondrinking, are involved in the initiation, maintenance, and cessation of alcohol use and are hypothesized to play key roles in adolescent decision making. This study explored (a) the relationships between alcohol use expectancies, nondrinking expectancies, and nondrinking motives; (b) the roles of these cognitions across hypothesized developmental stages of adolescent alcohol use; and (c) the relationships between these cognitions and recent or intended future changes in drinking behavior in a cross-sectional sample. Surveys assessing alcohol use behaviors and attitudes were administered to 1,648 high school students. Heavier drinkers reported more positive alcohol use expectancies and fewer nondrinking motives than did lighter drinkers or nondrinkers; however, nondrinking expectancies only differed between nondrinkers and rare drinkers and all subsequent drinking classes. Alcohol use expectancies, nondrinking expectancies, and nondrinking motives differentiated students who recently initiated alcohol from those who had not, while nondrinking expectancies and nondrinking motives differentiated binge-drinking students who had made recent efforts to reduce/stop their drinking from those who had not. Intentions to initiate or reduce drinking in the coming month were also associated with these alcohol-related cognitions. Drinking and nondrinking expectancies and motives for not drinking may play critical roles in decisions to alter alcohol-use behavior during adolescence. Future exploration of temporal relationships between changes in alcohol-related cognitions and behavioral decision making will be useful in the refinement of effective prevention and intervention strategies.

RESUMO

INTRODUCTION: A substantial number of adolescents are current and regular cigarette smokers, and there is a need to better understand factors that contribute to smoking behavior during these years. Sensation seeking (SS) is one factor that has consistently been associated with smoking, but less is known about mechanisms that may explain this relationship. METHODS: The present study tested the hypothesis that high school students high in SS would report heavier cigarette smoking and that this relationship would be mediated by negative affect and by perceptions about the risks of smoking. Students (n = 1,688) participated in an annual survey of substance use and related attitudes and characteristics. RESULTS: As expected, higher SS was associated with greater levels of past 30-day (odds ratio [OR] = 1.46, p = .004) and lifetime (OR = 1.37, p = .004) smoking, particularly for males. Multiple mediation models indicated that effect of SS on both 30-day (combined indirect effect z = 5.38, p < .001) and lifetime (z = 6.14, p < .001) smoking was mediated by both negative affect and risk perception. CONCLUSIONS: These findings suggest a need for increasing the sensation value of anti-tobacco messages to increase their efficacy for high SS youth. High SS youth may also benefit from prevention efforts designed to teach healthy ways of coping with negative affect.

RESUMO

OBJECTIVE: When asked about substance use, youths typically endorse higher levels of use than parents, suggesting that parents are often unaware of their child's drug and alcohol use. This study sought to examine the level of concordance between reports of youths enrolled in public sectors of care and their parents, and identify potential predictors of parental awareness of substance use and related problems. METHOD: Youths receiving services in one or more public sectors of care (N = 985; 67% male) and their parents were interviewed about the youths' substance use and substance use problems, as well as associated demographic, parental, and youth factors. RESULTS: As has been found in other studies, youths generally reported higher rates of substance use and substance use problems compared with parents. Rates of agreement ranged from κ = .24 (sedatives) to κ = .67 (marijuana) and were higher for drug problems (κ = .47) than for alcohol problems (κ = .34). Predictors of parental awareness of drug problems included youth gender (male), race (White compared with Hispanic), and higher ratings of youth's functional impairment. Predictors of parental awareness of alcohol problems included race (White compared with Hispanic), lower levels of youth-reported parental monitoring, lower levels of parental depression, and higher ratings of youth functional impairment. CONCLUSIONS: In this high-risk population, a significant proportion of parents are unaware of their child's alcohol (30%) and substance use (50%) problems. Services geared toward enhancing parental awareness, especially for parents of Hispanic and female youths, may increase communication and treatment seeking.

RESUMO

OBJECTIVE: This study examined the role of cognitive factors--such as expectancies regarding the consequences of not drinking and perceptions of peer drinking--in mediating affective and personality-based risk associated with adolescents' decisions to initiate alcohol use. METHOD: Nondrinking high school students (N = 1,268) completed confidential surveys on adolescent attitudes and behaviors related to substance use in 2 consecutive years. Self-reported alcohol use was assessed in both years, and social anxiety, depression, sensation seeking, expectancies for not drinking, and perceived peer alcohol use were assessed in the second year. RESULTS: The odds of initiation were considerably lower for students with higher expectancies for not drinking, compared with those with lower expectancies. Odds of initiation rose significantly with each additional perceived peer drink reported. Both cognitive factors mediated the relationships between social anxiety, depression, sensation seeking, and alcohol-use initiation. CONCLUSIONS: Beliefs regarding the consequences of not drinking and perceived peer drinking play key roles in the relationship between affective and personality styles on adolescent drinking. These cognitive differences may explain varying affective risk profiles for alcohol initiation and use during adolescence, and they can provide tools for prevention efforts.
