ABSTRACT. Objective: During adolescence, neurobiological maturation occurs concurrently with social and interpersonal changes, including the initiation of alcohol and other substance use. The National Consortium on Alcohol and NeuroDevelopment in Adolescence (NCANDA) is designed to disentangle the complex relationships between onset, escalation, and desistance of alcohol use and changes in neurocognitive functioning and neuromaturation. Method: A sample of 831 youth, ages 12-21 years, was recruited at five sites across the United States, oversampling those at risk for alcohol use problems. Most (83%) had limited or no history of alcohol or other drug use, and a smaller portion (17%) exceeded drinking thresholds. A comprehensive assessment of biological development, family background, psychiatric symptomatology, and neuropsychological functioning-in addition to anatomical, diffusion, and functional brain magnetic resonance imaging-was completed at baseline. Results: The NCANDA sample of youth is nationally representative of sex and racial/ethnic groups. More than 50% have at least one risk characteristic for subsequent heavy drinking (e.g., family history, internalizing or externalizing symptoms). As expected, those who exceeded drinking thresholds (n = 139) differ from those who did not (n = 692) on identified factors associated with early alcohol use and problems. Conclusions: NCANDA successfully recruited a large sample of adolescents and comprehensively assessed psychosocial functioning across multiple domains. Based on the sample's risk profile, NCANDA is well positioned to capture the transition into drinking and alcohol problems in a large portion of the cohort, as well as to help disentangle the associations between alcohol use, neurobiological maturation, and neurocognitive development and functioning.

Treatment outcomes of 126 adolescents (13-18 years old) with comorbid substance use disorders (SUDs) and Axis I psychiatric disorders (mood, anxiety, conduct, and attention-deficit/hyperactivity disorders) were compared to 81 SUD adolescents with no additional Axis I disorder. Participants completed structured interviews and symptom measures while participating in an adolescent treatment program and at 6 months following treatment. Results indicated that comorbid youth received more treatment during the outcome period; despite this, more comorbid SUD-Axis I disordered adolescents used substances following treatment than SUD-only youth, even after controlling for socioeconomic status and ethnicity. Among comorbid youth, internalizing disordered adolescents were less likely to use substances during the follow-up period, and externalizing disordered youth returned to substance use most rapidly after discharge from treatment.
The literature regarding the relationship between adolescent social anxiety and substance use is sparse, and available studies have produced discrepant results. Similarly, negative affectivity is a mood-dispositional dimension that is infrequently considered in studies of substance use. The authors used dispositional structural equation modeling to examine the concurrent relationships of social anxiety and negative affectivity with adolescent substance involvement among 724 students in 1 southern California high school. The final model indicated that increased substance use was associated with having lower grade-point average, being male, being White, having higher levels of negative affectivity, and having lower levels of social anxiety. The findings confirm that negative affectivity is positively related to adolescent substance use, whereas social anxiety appears to be protective against substance involvement.
Recent research highlights the role of peer victimization in students’ adjustment across a variety of domains (e.g., academic, social), but less often identifies potential mediating variables. In the current study, we tested for direct effects from peer victimization to adolescents’ academic behavior and alcohol use, as well as indirect effects through school belonging. Adolescents from two large samples (middle school: N = 2,808; high school: N = 6,821) self-reported on peer victimization, school belonging, academic outcomes (GPA, school truancy), and alcohol use (lifetime, past 30 days). Two-group structural equation models revealed (a) direct and indirect paths from peer victimization to academic functioning; (b) indirect, but not direct, effects through school belonging for lifetime drinking; and (c) direct and indirect effects from peer victimization to current drinking. Findings implicate school belonging as a mediator between peer victimization and important outcomes in adolescence.
Objective:The relation between social anxiety and alcohol consumption suggests aspects of both risk and protection, but most research has focused on late adolescents and emerging adults. Method: We investigated the synergistic impact of social anxiety, a need for affi liation with others, and perceived peer alcohol use on drinking in a sample of more than 1,500 early adolescents from southern California (48% girls). Via school-wide surveys, middle school students completed the Social Anxiety Scale for Children-Revised, a modifi ed version of the Interpersonal Orientation Scale, as well as measures of perceived peer drinking and self-reported lifetime and current drinking. Results: For socially anxious youths, high levels of perceived peer use in conjunction with high levels of affi liation need was associated with greater alcohol use on average and more frequent episodic drinking. Specifi c to heavy episodic drinking, the interaction of social anxiety and perceived peer drinking seemed to affect girls and boys differentially. Sex differences emerged for the moderation of social anxiety's infl uence on drinking initiation by perceived peer infl uence. Conclusions: These fi ndings suggest that alcohol-related risks associated with social anxiety might be gender specifi c and more important in earlier stages of alcohol use than previously believed.

The Eating Disorder Inventory-2 (EDI-2) and Bulimia Test-Revised (BULIT-R) have demonstrated strong reliability and validity in college students and adults. Although used in adolescent samples, little is known about the psychometric properties of these measures for adolescents. The reliability, factor structure, and mean levels of five EDI-2 scales and the BULIT-R were evaluated over 3 years. Data were collected yearly from two samples of adolescent females, one recruited from three public middle schools (n = 239, mean baseline age = 12.8) and one from two public high schools (n = 119, mean baseline age = 15.9). Results provide strong evidence for the reliability and stability of these measures. Mean levels of both measures appeared remarkably consistent over the 3 years. These results provide evidence of good psychometric performance for these scales in adolescence. The lack of change in these measures raises questions about the developmental trajectory of these variables through adolescence.
