In‐School Versus Out‐of‐School Friendships and Academic Achievement Among an Ethnically Diverse Sample of Adolescents

Much of the research on adolescent friendships and school achievement has focused on in‐school friends, ignoring the potential effects of having out‐of‐school friendships. The goal of this study was to examine the relation between having relatively more in‐school friends and school achievement among a sample of over 600 12th grade students from ethnically diverse backgrounds. We found that adolescents with more in‐school friends, compared with out‐of‐school friends, had higher grade point averages (GPAs) and that adolescents with higher GPAs had more in‐school friends. These relations were mediated by academic experiences, including those shared with friends. However, as hypothesized, the social aspects of adolescents' friendships did not vary according to their percent of in‐school friends, attesting to the importance of considering both types of friendships in understanding adolescents' social experiences. None of the relations described varied according to gender or ethnicity.     

A Latent Growth Curve Analysis of Prosocial Behavior Among Rural Adolescents

The present study was designed to investigate stability and changes in prosocial behavior and the parent and peer correlates of prosocial behavior in rural adolescents. Participants were from a rural, low SES community in the Eastern United States. The participants were in 7th, 8th, and 9th grades at Time 1 and 10th, 11th, and 12th grades at Time 4, and completed measures of prosocial behavior and quality of parent and peer relationships. Latent growth curve modeling revealed that despite moderate stability in individual differences in prosocial behavior and slight increases in quality of peer and parent relationships, level of prosocial behavior declined until late high school with a slight rebound in grade 12. Furthermore, increases in the quality of peer relationships predicted decreases in prosocial behavior for girls but not boys. Discussion focuses on continuity and change in prosocial behavior and the gender‐based relations between quality of parent and peer relationships and prosocial behaviors in adolescence.     

The Peer Context of Adolescent Substance Use: Findings from Social Network Analysis

To examine the peer context of adolescent substance use, social network analysis was used to measure three domains of attributes of peer networks: social embeddedness, social status, and social proximity to substance users. The sample was a panel of 5,104 sixth, seventh, and eighth graders in three public school systems surveyed every 6 months for five assessments. Hierarchical generalized linear models showed that adolescents less embedded in the network, with greater status, and with closer social proximity to peer substance users were more likely to use substances. Also, adolescents in less dense networks and networks with higher smoking prevalence were more likely to smoke and use marijuana. Results establish the utility of social network analysis for measuring peer context and indicate that conventionality of relationships—having friends in the network, being liked but not too well liked, and having fewer friends who use substances—is most beneficial.     

The development of science achievement in middle and high school. Individual differences and school effects

Using data from the Longitudinal Study of American Youth (LSAY), hierarchical linear models (HLMs) were used to model the growth of student science achievement in three areas (biology, physical science, and environmental science) during middle and high school. Results showed significant growth in science achievement across all areas. The growth was quadratic across all areas, with rapid growth at the beginning grades of middle school but slow growth at the ending grades of high school. At the student level, socioeconomic status (SES) and age were related to the rate of growth in all areas. There were no gender differences in the rate of growth in any of the three areas. At the school level, variables associated with school context (school mean SES and school size) and variables associated with school climate (principal leadership, academic expectation, and teacher autonomy) were related to the growth in science achievement. Initial (Grade 7) status in science achievement was not associated with the rate of growth in science achievement among either students or schools in any of the three areas.     

Socioeconomic Strain,Family Ties,and Adolescent Health in a Rural Northeastern County

In adolescence, vital sources of support come from family relationships; however, research that considers the health‐related impact of ties to both parents and siblings is sparse, and the utility of such ties among at‐risk teens is not well understood. Here we use two waves of panel data from the population of 8th and 12th grade students in a geographically isolated, rural, northeastern U.S. county to assess whether socioeconomic status (SES) moderates the effects of parental and sibling attachments on three indicators of adolescent health: obesity, depression, and problem substance use. Our findings indicate that, net of stressful life events, prior health, and sociodemographic controls, increases in parental and sibling attachment correspond with reduced odds of obesity for low‐SES adolescents, reduced odds of depression for high‐SES adolescents, and reduced odds of problem substance use for low‐SES adolescents. Results suggest also that sibling and maternal ties are more influential than paternal ties, at least with regard to the outcomes considered. Overall, the findings highlight the value of strong family ties for the physical, psychological, and behavioral health of socioeconomically strained rural teens, and reveal the explanatory potential of both sibling and parental ties for adolescent health.     

Developmental Outcomes of School Attachment Among Students of Mexican Origin

We used a longitudinal community study of 674 grade school children (Grades 5, 6, 7, and 8; 337 males, 337 females) of Mexican origin to examine outcomes of school attachment. Attachment to school is important in this population given the high level of school dropout rates of Mexican‐origin students. Results indicated that, on average, school attachment from fifth to sixth grade remains stable, but declines from sixth to eighth grade. Boys had lower levels of school attachment at fifth grade but followed similar patterns of change as girls did. Attachment to teachers, peer competence, school aspirations and expectations, and substance‐use cognitions emerged as longitudinal outcomes of level or changes in school attachment. Gender moderated associations of school attachment.     

How Academic Achievement,Attitudes, and Behaviors Relate to the Course of Substance Use During Adolescence: A 6‐Year,Multiwave National Longitudinal Study

Self‐report data regarding alcohol, cigarette, and marijuana use were collected biennially from ages 14 to 20 in a nationally representative panel sample of adolescents (N=1,897) from the Monitoring the Future study. Growth curve analyses were performed using hierarchical linear modeling to consider psychosocial background, motivation and school attitudes, and parental and peer influences at age 14 as predictors of concurrent substance use and change in substance use. Results indicated that school misbehavior and peer encouragement of misbehavior were positively associated with substance use at age 14 and with increased use over time; school bonding, school interest, school effort, academic achievement, and parental help with school were negatively associated. The protective effects of positive school attitudes and perceptions of high status connected to academics were stronger for low‐achieving compared with high‐achieving youth. Implications for a developmental perspective on substance use etiology and prevention are discussed.     

Preludes to Attainment: Race,Sex, and Student Achievement Orientations*

This paper investigates race-sex differences in achievement orientation using a national sample of high school seniors. Achievement orientation is approximated by attitudinal measures (educational expectations, occupational aspirations, academic self concept, self esteem, and locus-of-control) known to be correlated with expected and actual attainments. Three major sets of student background factors are related to ent orientation: (1) family SES, (2) school context, and (3) parental expectations. Race-sex comparisons of achievement orientation revealed several interesting, but few definitive differences. Occupational aspirations were a dimension of consistent differentiation: whites and males aspired to higher status, less stereotypic occupations than did blacks and females. Pronounced interpersonal effects are implied throughout, with family educational attainments, peer plans, teacher evaluations (grades) and parent aspirations strongly influencing achievement orientations in all race-sex subgroups. The paper calls for intensive, longitudinal studies of student interactions with parents, friends, teachers, and other individuals who influence their perceptions of what constitute desirable and possible future roles.     

Internalizing Symptoms,Peer Substance Use,and Substance Use Initiation

This study used longitudinal survey and social network data covering sixth through ninth grades to test whether internalizing symptoms make early adolescents more prone to (1) exposure to and (2) influence by substance‐using peers. Random effects regressions revealed that increases in symptoms were significantly associated with increases in the proportion of friends who used cigarettes, alcohol, and marijuana; some associations weakened across grades. Event history models revealed that the effect of friends' smoking on smoking initiation decreased as internalizing symptoms increased; symptoms did not moderate the effects of friends' alcohol and marijuana use on alcohol and marijuana use initiation. These findings counter the influence hypothesis of the co‐occurrence of internalizing symptoms with substance use and partly support the exposure hypothesis.     

Popularity breeds contempt: The evolution of reputational dislike relations and friendships in high school

In this study, we examined the dynamics of the perception of “dislike” ties (reputational dislike) among adolescents within the contexts of friendship, perceived popularity, substance use, and Facebook use. Survey data were collected from a longitudinal sample of 238 adolescents from the 11th and 12th grades in one California high school. We estimated stochastic actor-based network dynamic models, using reports of reputational dislike, friendships, and perceived popularity, to identify factors associated with the maintenance and generation reputational dislike ties. The results showed that high-status adolescents and more frequent Facebook users tended to become perceived as or stay disliked by their peers over time. There was a tendency for friendships to promote the creation and maintenance of reputational disliking but not vice versa. Adolescents tended to perceive others as disliked when their friends also perceived them as disliked. There was no evidence that either cigarette smoking or drinking alcohol affected reputational dislike dynamics. This study highlights the important role that the hierarchical peer system, online peer context, and friendships play in driving information diffusion of negative peer relations among adolescents.     

Risk and protective factors for recent alcohol use among African-American youth

A total of 7488 7th-12th grade African-American students completed a survey assessing factors associated with recent alcohol use. Results indicated that 13.6% used alcohol in the past month. A series of odds ratios revealed that making good grades, participating in school activities, attending church, and having parents/teachers talk about the dangers of alcohol and set/enforce rules regarding alcohol were associated with decreased recent use. Participating in risky behaviors such as getting into trouble, skipping school, and having friends who use alcohol and other drugs was directly related to recent use. Prevention specialists should encourage parents/teachers to engage youth in family, school, and community activities to deter alcohol use. Results may assist youth health professionals in developing prevention programs aimed at African-American youth.     

SEX DIFFERENCES IN SCHOOL PERFORMANCE DURING HIGH SCHOOL: Puzzling Patterns and Possible Explanations

While past explanations for sex differences in school performance are heavily geared toward explaining boys’ small advantage on standardized math tests, we broaden the focus to include educational outcomes for which girls typically do well—standardized reading tests and math and English grades. Among adolescents in the National Education Longitudinal Study, girls enjoy better English and math grades and higher reading test scores than boys in eighth grade and these advantages all increase during high school. In contrast, boys earn slightly higher math test scores in eighth grade and this gap also increases slightly by the end of high school. This set of patterns leaves us with a puzzle—why do girls and boys excel at different components of schooling? We explore models that assess the degree to which these different trajectories can be explained by sex differences in classroom behavior and out‐of‐class activities. We conclude that a major reason for sex differences in grades is boys’ poorer classroom behavior while sex differences in time spent outside of school should supplement previous explanations for test scores gaps.     

Breadth of Extracurricular Participation and Adolescent Adjustment Among African-American and European-American Youth

We examined the linear and nonlinear relations between breadth of extracurricular participation in 11th grade and developmental outcomes at 11th grade and 1 year after high school in an economically diverse sample of African-American and European-American youth. In general, controlling for demographic factors, children's motivation, and the dependent variable measured 3 years earlier, breadth was positively associated with indicators of academic adjustment at 11th grade and at 1 year after high school. In addition, for the three academic outcomes (i.e., grades, educational expectations, and educational status) the nonlinear function was significant; at high levels of involvement the well-being of youth leveled off or declined slightly. In addition, breadth of participation at 11th grade predicted lower internalizing behavior, externalizing behavior, alcohol use, and marijuana use at 11th grade. Finally, the total number of extracurricular activities at 11th grade was associated with civic engagement 2 years later.     

Friendless Adolescents: Do Perceptions of Social Threat Account for Their Internalizing Difficulties and Continued Friendlessness?

Adolescents who lack friends at school are at risk of internalizing difficulties. This study examined a social‐cognitive mechanism underlying friendlessness and internalizing difficulties (i.e., depressive symptoms, social anxiety, low self‐esteem). We tested whether perceived social threat (i.e., peer victimization, sense of unsafety, and peer misconduct) mediates the association between friendlessness and increased internalizing difficulties across middle school. Latent variable structural equation modeling was used to test the model among an ethnically diverse sample of 5,991 (52% female) adolescents. The results demonstrate that friendless sixth‐grade students perceived their school environment as more threatening by seventh grade, which in turn, increased internalizing difficulties from sixth to eighth grade. Perceptions of threat also predicted friendlessness at the end of middle school.     

Adolescent Behavioral,Emotional, and Cognitive Engagement Trajectories in School and Their Differential Relations to Educational Success

The current study used a multidimensional approach to examine developmental trajectories of three dimension of school engagement (school participation, sense of school belonging, and self‐regulated learning) from grades 7 to 11 and their relationships to changes in adolescents’ academic outcomes over time. The sample includes 1,148 African American and European American adolescents (52% females, 56% black, 34% white, and 10% others). As expected, the downward trajectories of change in school participation, sense of belonging to school, and self‐regulated learning differed as did their predictive relationships with academic performance and educational aspiration, with school belonging declining most markedly, but being least predictive of changes in grade point average.     

Socioeconomic Context and Emotional‐Behavioral Achievement Links: Concurrent and Prospective Associations Among Low‐ and High‐Income Youth

Temporal associations in the relationship between emotional‐behavioral difficulty and academic achievement were explored in 2 samples followed from 6th through 8th grade. The first sample comprised 280 students entering an economically disadvantaged urban middle school and the second comprised 318 students entering an affluent suburban middle school. Among disadvantaged youth, emotional indices were concurrently associated with poorer achievement while prospective associations between substance use and achievement were evident. For privileged adolescents, only a significant concurrent relationship emerged between social anxiety and achievement, although nonsignificant trends in the data suggest other, albeit weak, associations. The findings are discussed in terms of similarities and differences in these temporal associations across 2 samples representing extremes of the socioeconomic continuum.     

Long-term impact of a district-wide school/community-based substance abuse prevention initiative on gateway drug use

This study examined long-term effects of a school/family/community substance abuse prevention partnership intervention lead by a Midwestern school district. Previous findings suggested that the program contributed to decreased tobacco and marijuana, but not alcohol, use prior to and after implementation between 1987 and 1991. The current study examined 8th-12th grade student drug use prevalence data from 1991 and 2003 to determine whether previous program effects were sustained. With one exception, reported lifetime and monthly cigarette use decreased below 1991 levels for all grades. Lifetime and monthly alcohol use decreased below 1991 levels for most grades, a result not previously detected. While still below national rates, reported lifetime use of marijuana increased for all grades over time. The intervention was effective in reducing cigarette and alcohol use over time and in suppressing marijuana use levels below national rates; however, these gains tended to erode in later high school grades.     

Changes in Parent,Sibling, and Peer Support During the Transition to Young Adulthood

Longitudinal trajectories of parent, sibling, and peer support during the transition to young adulthood were compared among 600 participants (51.1% female) from Asian, European, and Latin American backgrounds. Participants completed questionnaires at 12th grade, 2 and 4 years after high school. Results indicated that parent support increased across this period for participants from European backgrounds but remained stable for participants from Asian and Latin American backgrounds. Peer and sibling support remained relatively stable. Supports had specific implications for self‐esteem and depressive mood. On average, young adults with higher levels of support reported greater expectations to reciprocate support within the family. Together, these findings highlight the changing dynamics of family and friends during the transition to young adulthood.     

The impact of the "I'm Special" Program on student substance abuse and other related student problem behavior

There has been a proliferation of school-based substance abuse prevention programs geared toward reducing or delaying the onset of student use of illegal drugs. But the field has shown a general absence of evaluation dealing with the behavior consequences of these practices. This article fills this gap by using the case of the "I'm Special" Program (ISP) targeted for fourth grade students. Using a quasi-experimental design, a comparison is made between the substance using and other problem behavior of students who have been exposed to the ISP and those who have not during their later school years in grades 5 through 12. At the aggregate level, the proportions of current substance users and the incidence of their related problem behavior were significantly lower among the ISP graduates than those who have not been exposed to the program. In particular, there were consistently lower proportions of current substance users among the ISP recipients than the non-recipients in grades 5-7. However, the impact of the ISP seems to diminish significantly in and around ninth grade. During the senior high level, the pattern revealed is almost random. And, in some drug categories, it has been speculated that the ISP students were trying to "catch up" with what they may have missed out on during earlier grade levels.     

Peer influence and drug use among adolescents in rural areas

A sample of 1,004 eighth and tenth grade students in twenty-three small Central/East Texas communities was assessed to determine 1) their perception of the number of their friends who use drugs, 2) the amount of information they received about drugs from their friends, and 3) the connection between those perceptions and drug use. A multiple regression model which included grade, gender, the degree to which friends are perceived to use drugs and the amount of information about drugs received from friends explained 39 percent of the variance in the degree to which rural adolescents were involved in drug use. An item specific analysis of the subcomponents of these composite variables explained 44 percent of the variance in the degree to which rural adolescents were involved in drug use. This same four-factor model accurately classified over 81 percent of non-drug-users and 67 percent of users using discriminant analysis. Students who perceived a higher degree of drug use among their friends and who received more information about drugs from their friends used drugs more frequently. Lower marijuana use in these rural areas as compared to the nation, both as a peer perception and as a fact, may protect these students to a degree from broader patterns of drug use. The findings of this study support the theory that peer pressure is related to drug abuse, even in rural areas.
