Patterns of substance use in early through late adolescence

This study examined patterns of substance use throughout adolescence. A cluster analytic approach was used to identify subgroups of adolescents on the basis of their levels of substance use from early through late adolescence (Grades 6 through 11). Six distinct clusters of substance users emerged—2 groups representing relatively stable patterns of substance use from early through late adolescence (i.e., nonusers and alcohol experimenters), and 4 groups of users showing escalating patterns of substance use (i.e., low escalators, early starters, late starters, and high escalators). The study provides a comprehensive view of adolescent substance use by examining the progression of use from early to late adolescence, demonstrates the usefulness of studying patterns of use across multiple substances, and underscores the importance of building classification schemes based on repeated measurements of substance use to reflect changes over time. Implications of the findings for future research and for identifying high-risk subgroups of adolescents for purposes of intervention based on timing and pattern of escalation are discussed.     

Pubertal status associations with reward and threat sensitivities and subcortical brain volumes during adolescence

Adolescence is characterized by complex developmental processes that impact behavior, biology, and social functioning. Two such adolescence-specific processes are puberty and increases in reward sensitivity. Relations between these processes are poorly understood. The present study focused on examining unique effects of puberty, age, and sex on reward and threat sensitivities and volumes of subcortical brain structures relevant for reward/threat processing in a healthy sample of 9–18 year-olds. Unlike age, pubertal status had a significant unique positive relationship with reward sensitivity. In addition, there was a trend for adolescent females to exhibit higher threat sensitivity with more advanced pubertal development and higher reward and threat sensitivity with older age. Similarly, there were significant puberty by sex interaction effects on striatal volumes, i.e., left nucleus accumbens and right pallidum. The present pattern of results suggests that pubertal development, independent of chronological age, is uniquely associated with reward hypersensitivity and with structural differences in striatal regions implicated in reward processing.     

Family timing in late adolescence and early adulthood: The case of southern males

Social science research and theory about familial orientations and reproductive ideals have largely neglected males' attitudes. Drawing on demographic and status attainment perspectives, this study applies a model of processes underlying marriage and family timing to longitudinal data on 288 young adult males from the Southern Youth Study. Several posited influences of family of origin factors, significant others, and adolescent status and familial aspirations on marital timing and early family growth are assessed.Development of this report was sponsored in part by the Texas Agricultural Experiment Station and contributes both to TAES Project H-2811 and to USDA (CSRS) Regional Research Project S-81, and in part by the Maxwell Policy Center on Aging and the All-University Gerontology Center, Syracuse University through Title IV-C Grant #90-A-1054101 from the Administration on Aging, Department of Health, Education, and Welfare. Information for analysis was obtained by pooling data collected under grants provided by the Agricultural Experiment Stations of Alabama, Georgia, South Carolina, and Texas. Appreciation is expressed to John Womack, Paul D. Mader, and G. David Curry for their advice at various stages of this research.     

Latent growth modeling of the relationship between depressive symptoms and substance use during adolescence.

To explicate the nature of the relationship between depressive symptoms and substance use, the authors conducted research that incorporated both individual and group approaches and utilized longitudinal data across development. Multiple-group latent growth curve models were used to assess specific dimensions (cross-sectional and longitudinal correlation, within-individual change, and movement off developmental trajectories) of the relationship between depressive symptoms and substance use during adolescence and how this relationship differs by gender. Annual survey data from 8th through 11th grade were provided by 441 girls and 510 boys in the Raising Healthy Children project (E. C. Brown, R. F. Catalano, C. B. Fleming, K. P. Haggerty, & R. D. Abbott, 2005). Levels of depressive symptoms and substance use in early adolescence were positively associated for alcohol, marijuana, and cigarette use for girls, but only for marijuana use for boys. Individual changes in depressive symptoms and substance use across adolescence were positively associated for each type of substance use. Evidence was also found for positive association between episodic expressions of depressive symptoms and alcohol use that fell outside developmental trajectories. Predictive relationships across constructs were not found, with the exception of higher level of depressive symptoms in early adolescence predicting less increase in alcohol use.     

Longitudinal associations between impulsivity and lie-telling in childhood and adolescence

Lie-telling and impulsivity levels peak during late childhood to early adolescence and have been suggested to be related. Heightened impulsivity may lead adolescents to lie in favor of short-term benefits without consideration for the potential consequences of deception. The present study assessed longitudinal relations between self-reported impulsivity and lie-telling frequency. Participants from a large-scale longitudinal study (N = 1148; M_age = 11.55, SD = 1.69, 9–15 years at Time 1) reported on their impulsivity (Barratt Impulsiveness Scale) and their frequency of lie-telling to parents, to teachers, to friends, and about cheating across two time points 1 year apart. Cross-lagged path analysis revealed greater impulsivity was associated with more frequent lie-telling to parents, friends, and teachers, and about cheating over time. Our findings demonstrate the role of impulsivity in the development of lie-telling behaviors.

Research Highlights

• Impulsivity predicts lying across time in multiple contexts (to parents, friends, teachers, and about cheating).
• Previous research has demonstrated the role of top-down influences on lie-telling, but the current study suggests that bottom-up processes are also influential.

     

A longitudinal study of antisocial behaviors in early adolescence as predictors of late adolescent substance use: gender and ethnic group differences

Data from the National Longitudinal Youth Survey (NLSY) were analyzed to study interrelationships between antisocial behaviors in early adolescence (ages 14-15) and late adolescent alcohol and drug use 4 years later (when adolescents were 18-19). Correlations between classes of antisocial behaviors in early adolescence and substance use in late adolescence were of higher magnitude and more uniform for men than for women; for women, property offenses (e.g., vandalism) in early adolescence were more highly associated with alcohol use, alcohol-related problems, and illicit drug use in late adolescence than with either status offenses or transgressions against persons. Multiple regression analyses indicated that early-adolescent substance involvement was a significant predictor of late-adolescent alcohol and drug use. Additional significant predictors included early adolescent general delinquency, male gender, and non-Black ethnicity.     

Developmental trajectories of aggression from late childhood through adolescence: similarities and differences across gender

Although numerous investigations of overt aggressive and antisocial trajectories have been undertaken, there is a dearth of literature examining gender differences and similarities in trajectory patterns and their correlates. To address these gaps, we investigated gender differences in the prevalence rates, predictive validity during transition to adulthood, childhood risk factors, and adolescent correlates of different trajectories of teacher-reported overt aggression (i.e., fights, argues, gets in trouble) among 220 participants (116 girls and 104 boys) evaluated annually from grade 4 to grade 12. Four patterns of trajectories were identified: low, increasing (i.e., adolescent-onset), decreasing (i.e., childhood-limited), and high (i.e., childhood-onset). A large proportion of youth, particularly girls, displayed low levels of aggression over time. A small proportion followed the childhood-onset trajectory. Across gender, the childhood-onset trajectory was associated with the highest rates of maladjustment during the transition to adulthood, the highest number of childhood risk factors, and multiple problems during adolescence. The adolescent-onset trajectory was associated with few childhood risk factors, but with high levels of independent status during adolescence. In contrast, the childhood-limited trajectory was associated with several childhood risk factors, but high levels of parental monitoring and school engagement during adolescence. Romantic involvement differentiated the adolescent-onset and childhood-limited trajectories among girls.     

Moderators of the relation between substance use level and problems: test of a self-regulation model in middle adolescence

The authors tested predictions, derived from a self-regulation model, about variables moderating the relationship between level of substance use (tobacco, alcohol, and marijuana) and problems associated with use. Data were from two independent studies of adolescents, with mean ages of 15.4 and 15.5 years (Ns = 1,699 and 1,225). Factor analysis indicated correlated dimensions of control problems and conduct problems. Protective moderation was found for variables indexing good self-control; risk-enhancing moderation was found for variables indexing poor self-control. These effects were generally independent of deviance-prone attitudes and externalizing symptomatology. Multiple-group structural modeling indicated moderation occurred for paths from life stress and coping motives and for paths from level to control and conduct problems. Moderation effects were also found for parental variables, peer variables, and academic competence.     

Linking childhood personality with adaptation: evidence for continuity and change across time into late adolescence

Four personality traits--Mastery Motivation, Academic Conscientiousness, Surgent Engagement, and Agreeableness--were measured in a community sample of 205 children (ages 8-12), who were followed up 10 years later. Childhood personality was examined in relation to concurrent and longitudinal adaptation in 3 domains--academic achievement, rule-abiding versus antisocial conduct, and peer social competence. The childhood personality traits evidenced robust, conceptually coherent relationships with adaptation, both concurrently and across time. Childhood personality added to the prediction of later adaptation, beyond childhood IQ and earlier adaptation in the same domain. Few sex differences were obtained in the relationships between childhood personality and adaptation. The present results document both continuity and discontinuity in the links between childhood personality and adaptation across childhood into late adolescence.     

Prospective associations between social status and social anxiety in early adolescence

This study examined the transactional longitudinal association between social status (likeability and popularity) and social anxiety symptoms (fear of negative evaluation and social avoidance and distress), and explored gender differences in this association. Participants included 274 adolescents (136 boys, M_age = 12.55). Data were collected at two waves with a 6-month interval. Likeability and popularity were measured with peer nominations and social anxiety symptoms with self-reports. Autoregressive cross-lagged path models showed relative stability of social status and social anxiety. Girls who were seen as less popular by their classmates avoided social situations more frequently and experienced more distress during such situations over time. These results highlight the importance of distinguishing between different social status components and social anxiety symptoms and to take gender into account. Early support for less popular girls seems important to prevent more severe consequences of avoidance and distress, such as social exclusion and victimization.     

Differences in protective factors of substance use in early and middle adolescence

This study focuses on possible differences in protective factors of substance use in early and middle adolescence. These possible differences are analysed by means of the same structural equation model applied to two different samples of adolescents: the first sample is made up of 450 adolescents, ages 12 to 14 years, and second of 203 adolescents, ages 15 to 17 years. The results indicate that adequate family communication is a protective factor in both samples, whereas high social self-esteem is proposed as a risk factor in middle adolescence. The adolescent's family self-esteem and attitudes towards authority are also relevant factors in both samples. These results may have important implications in the development of future intervention programmes.     

Stress and coping in early adolescence: relationships to substance use in urban school samples

Measures of stress and coping were obtained from two cohorts of urban adolescents during the seventh- to eighth-grade period and were related to indices of cigarette smoking and alcohol use. Predictions were derived from a stress coping model of substance use. Stress was indexed by measures of subjective stress, recent events, and major life events; coping was assessed by behavior-based and intention-based methods. Concurrent and prospective analyses were consistent with predictions, indicating that stress was positively related to substance use, and four coping mechanisms (behavioral coping, cognitive coping, adult social support, and relaxation) were inversely related to substance use. Two types of predicted interactions, Stress X Coping and Positive X Negative Events, were found. Measures indexing peer support, distraction coping, and aggressive coping were positively related to substance use, independent of other predictors. Implications for substance use theory and prevention research are discussed.     

A longitudinal analysis of friendships and substance use: bidirectional influence from adolescence to adulthood

The reciprocal relation between deviant friendships and substance use was examined from early adolescence (age 13-14) to young adulthood (age 22-23). Deviance within friendships was studied using direct observations of videotaped friendship interaction and global reports of deviant interactions with friends as well as time spent with friends. Substance use was assessed through youth self-report at all time points. Multivariate modeling revealed that substance use in young adulthood is a joint outcome of friendship influence and selection processes. In addition, substance use appears to influence the selection of friends in late adolescence. Findings suggest that effective preventions should target peer ecologies conducive to substance use and that treatment should address both the interpersonal underpinnings and addiction processes intrinsic to chronic use, dependence, and abuse.     

Self-reported use of different forms of aggression in late adolescence and emerging adulthood

Two studies investigated the psychometric properties of a self-report measure of commonly recognized forms of aggression (FOA) that could be used to efficiently gather aggression data in large samples. EFA and CFA in Study 1 suggested that a five-factor model (Physical, Property, Verbal, Relational, and Passive-Rational) best represented the data across high school and college students. However, factor analyses in Study 2 using an ethnically diverse university sample revealed a four-factor solution (combining Physical and Property items). As a confirmation of the construct validity of FOA, physical and property aggression were lower, and verbal and passive-rational aggression were higher in college versus high school students. Gender differences were observed across FOA subscales, except relational aggression. FOA subscales correlated as expected with other anger and personality scales. Overall, the data revealed adequate psychometric properties for the FOA and suggest that current category distinctions (e.g., direct-indirect) may not adequately account for different forms of aggression. Researchers may want to reevaluate these categories.     

Longitudinal study of defense mechanisms: late childhood to late adolescence

Based on longitudinal data from the Institute of Human Development Intergenerational Study, the use and change in defense mechanisms of more than 150 individuals, as assessed from TAT stories, was studied across ages 11, 12, and 18. The findings of this study, based on an earlier generation, were generally consistent with cross-sectional findings from current samples, showing that the defenses of projection and identification were used more frequently than denial at all three ages and that the use of projection and identification increased from early to late adolescence. However, unlike current findings, the 18-year-olds did not show greater use of identification than of projection, perhaps due to IQ differences between this community sample and the samples of more recent studies.     

Bidirectional associations between biased language exposure and school-based relationships across gender

Students often hear their peers use biased language regarding race, religion, sexual orientation, or disability status in the school setting. Prior research has indicated that biased language is related to school climate, and specifically to school-based relationships between peers and between students and their teachers. This study investigated the longitudinal associations among student-student relationships, teacher-student relationships, and being the target of or hearing biased language in middle school students. Students (N = 501; 46.5% White, 21.8% Hispanic, 13% African American, and 15% Multi-Racial; 48.7% female) reported on how much they were targeted or heard biased language related to race/religion, sexual orientation, and disability status. Students also reported on their relationships with their peers and teachers. Using a cross-lagged panel model with the overall sample, a negative unidirectional association from being the target of or hearing biased language and student-student relationships and teacher-student relationships was identified. Separate models for boys and girls identified unique patterns. For boys, biased-language exposure predicted more negative student-student relationships and teacher-student relationships, whereas for girls, biased-language exposure was not associated with school-based relationships. Implications include addressing language use and building positive student-student and teacher-student relationships.     

Bidirectional pathways between relational aggression and temperament from late childhood to adolescence

Relational aggression is linked to numerous adverse consequences. However, we know little about how temperament leads individuals to become perpetrators/victims of relational aggression, or how being a perpetrator/victim influences the development of temperament. We used longitudinal data from 674 Mexican-origin youth to examine relations between relational aggression and mother- and child-reported temperament from 5th grade (M_age = 10.8; SD = 0.60) through 11th grade (M_age = 16.8; SD = 0.50). Results show that: (a) high Negative Emotionality and low Effortful Control predicted increases in victimization; (b) low Effortful Control predicted increases in perpetration; (c) victims increased in Negative Emotionality and decreased in Effortful Control; and (d) perpetrators increased in Negative Emotionality and Surgency. Thus, temperament serves as both an antecedent to and a consequence of relational aggression.
