Trajectories of Boys' Physical Aggression, Opposition, and Hyperactivity on the Path to Physically Violent and Nonviolent Juvenile Delinquency

A semi-parametric mixture model was used with a sample of 1,037 boys assessed repeatedly from 6 to 15 years of age to approximate a continuous distribution of developmental trajectories for three externalizing behaviors. Regression models were then used to determine which trajectories best predicted physically violent and nonviolent juvenile delinquency up to 17 years of age. Four developmental trajectories were identified for the physical aggression, opposition, and hyperactivity externalizing behavior dimensions: a chronic problem trajectory, a high level near-desister trajectory, a moderate level desister trajectory, and a no problem trajectory. Boys who followed a given trajectory for one type of externalizing problem behavior did not necessarily follow the same trajectory for the two other types of behavior problem. The different developmental trajectories of problem behavior also led to different types of juvenile delinquency. A chronic oppositional trajectory, with the physical aggression and hyperactivity trajectories being held constant, led to covert delinquency (theft) only, while a chronic physical aggression trajectory, with the oppositional and hyperactivity trajectories being held constant, led to overt delinquency (physical violence) and to the most serious delinquent acts.     

Trajectories of Physical Discipline: Early Childhood Antecedents and Developmental Outcomes

This study examined childhood antecedents and developmental outcomes associated with trajectories of mild and harsh parental physical discipline. Interview, questionnaire, and observational data were available from 499 children followed from ages 5 to 16 and from 258 children in an independent sample followed from ages 5 to 15. Analyses indicated distinct physical discipline trajectory groups that varied in frequency of physical discipline and rate of change. In both samples, family ecological disadvantage differentiated the trajectory groups; in the first sample, early child externalizing also differentiated the groups. Controlling for early childhood externalizing, the minimal/ceasing trajectory groups were associated with the lowest levels of subsequent adolescent antisocial behavior in both samples and with parent–adolescent positive relationship quality in the second sample.     

Trajectories of early childhood family instability and the development of externalizing behaviors from middle childhood to adolescence: A prospective study of at-risk families

This study examined associations between trajectories of family instability across early childhood and trajectories of externalizing behaviors from middle childhood to adolescence. Growth mixture models were fit to annual caregiver reports of instability from child ages 2–5 (N = 731; 49% girls, 50% White). A curve of factors model was fit to externalizing behaviors from child ages 7.5–14. Chronic, elevated instability across early childhood predicted elevated externalizing behaviors from middle childhood to adolescence. Data collection spanned from 2002 to 2017. Increasing or declining levels of instability predicted elevated externalizing behaviors in middle to late childhood, but not in adolescence. Caregiver depressive symptoms mediated the association between instability and the externalizing behavior intercept. Intervening on chronic instability may reduce child externalizing problems.     

Longitudinal trajectories of ethnic identity among urban Black and Latino adolescents

The current study modeled developmental trajectories of ethnic identity exploration and affirmation and belonging from middle to late adolescence (ages 15-18) and examined how these trajectories varied according to ethnicity, gender, immigrant status, and perceived level of discrimination. The sample consisted of 135 urban low-income Black and Latino adolescents (42% male, 34% Black, 66% Latino). Consistent with developmental theory, individual growth modeling identified an average quadratic trajectory of ethnic identity exploration characterized by decelerating levels of exploration after 10th grade. However, ethnicity and perceived discrimination by peers moderated this pattern. No uniform growth pattern in affirmation was found and Black and Latino adolescents displayed equally high levels of affirmation over time.     

Behavior problems in elementary school among low-income boys: The role of teacher–child relationships

The authors identified trajectories of teacher–child relationship conflict and closeness from Grades 1 to 6, and associations between these trajectories and externalizing and internalizing behaviors at 11 years old among low-income, urban boys (N = 262). There were three main findings. Nagin cluster analyses indicated five trajectories for conflict with all children evidencing increases in conflict, and four trajectories for closeness with all children demonstrating decreases in closeness. Trajectories with higher levels of conflict and lower levels of closeness were associated with higher levels of externalizing and internalizing behavior problems at 11 years old. Moreover, conflictual teacher–child relationships exacerbated the effects of externalizing and internalizing behavior problems in early childhood; children with conflictual teacher–child relationships had higher levels of behavior problems in middle childhood relative to children with low conflictual teacher–child relationships. Implications of targeting teacher–child relationships as interventions to help prevent behavior problems are discussed.     

Early school dropout: configurations and determinants

This longitudinal study examined behavioral, cognitive, and demographic factors associated with early school dropout. Follow-up assessments were completed on a sample of girls (n = 248) and boys (n = 227) who had first been seen when they were in the seventh grade. School status was determined for all living subjects; 99% of them were interviewed individually in the fifth annual test wave. Overall, 14% of the group had dropped out of school prior to completing grade 11. The clusters of males and females most vulnerable to early school dropout were characterized in grade 7 by high levels of aggressiveness and low levels of academic performance (82% early dropout in males; 47% early dropout in females). In seventh grade, subjects who subsequently dropped out tended to affiliate with persons who were also at risk for dropout. Socioeconomic status, race, and early parenthood were also associated with school dropout. The primary outcomes were supported by convergent variable-oriented and person-oriented analyses. Some developmental dynamics of the phenomena are discussed.     

Differential susceptibility to adolescent externalizing trajectories: examining the interplay between CHRM2 and peer group antisocial behavior

The present study characterized prototypical patterns of development in self-reported externalizing behavior, between 12 and 22 years of age, within a community sample of 452 genotyped individuals. A Caucasian subset (n = 378) was then examined to determine whether their probabilities of displaying discrete trajectories were differentially associated with CHRM2, a gene implicated in self-regulatory processes across a range of externalizing behaviors, and if affiliating with antisocial peers moderated these associations. Findings indicate that relative to a normative "lower risk" externalizing trajectory, likelihood of membership in two "higher risk" trajectories increased with each additional copy of the minor allelic variant at CHRM2, and that this association was exacerbated among those exposed to higher levels of peer group antisocial behavior.     

Father involvement in child welfare: Associations with changes in externalizing behavior

Nonresident fathers can have a significant impact on children's behavioral outcomes. Unfortunately, the impact of nonresident father involvement on the behavioral outcomes of children with child welfare involvement has received scant attention in the literature, a limitation the current study sought to address. A sample of 333 children in state custody in Illinois between the ages of six and 13 participated and were assessed using the externalizing behavior scale of the Child and Adolescent Needs and Strengths (CANS) at regular intervals throughout their time in care. Father involvement was measured through a review of case files and interviews with child welfare workers. Growth trajectories were fit to children's externalizing behavior across time and were predicted using Time 1 characteristics. Father involvement, total non-father relative involvement, and gender (girls) was associated with lower baseline externalizing behavior and the African American children in the sample experienced higher baseline externalizing behavior. However, only Time 1 father involvement predicted slope trajectories after controlling for Time 1 externalizing behavior; more father involvement was associated with lower externalizing behavior trajectories. These results suggest that even in the unique and stressful context of child welfare, father involvement can be protective regarding children's externalizing behaviors.     

A Longitudinal Investigation of African American and Hispanic Adolescents' Educational and Occupational Expectations and Corresponding Attainment in Adulthood

Adolescents' expectations about school and work may be key antecedents of adult attainment and this relationship may vary by specific racial, ethnic, and gender groups. This article examines how educational and occupational expectations change in adolescence and how expectations predict corresponding attainment in adulthood. Participants included African American and Hispanic females and males. Educational and occupational expectations were reported at ages 14, 16, and 18, and educational and occupational attainment at ages 20 and 26. Results indicated distinct developmental trajectories per racial or ethnic and gender group. Educational expectations were more nuanced for African American and Hispanic females than for their male counterparts; occupational expectations were more varied for Hispanic females than for other groups. Educational expectations positively predicted educational attainment for all participants, whereas occupational attainment was predicted just by educational expectations and for Hispanic females and males only.     

Emotional intelligence throughout Portuguese secondary school: a longitudinal study comparing performance and self-report measures

This study examines the developmental trajectories of ability and trait emotional intelligence (EI) in the Portuguese secondary school. Within a three-wave longitudinal design, 395 students (M _age ?=?15.4; SD?=?.74) completed both the Emotional Skills and Competence Questionnaire (ESCQ) and the Vocabulary of Emotions Test (VET). Results revealed that EI exhibited different developmental trajectories during late adolescence according to the type of measure used, while students’ VET levels evidenced an increase during secondary school, their ESCQ levels remained stable during this period. Moreover, students’ gender, verbal indicator, and type of school (public vs. private) have no significant effect on their rate of EI change, whereas students from lower sociocultural and lower professional status backgrounds demonstrated significantly greater increases on the ESCQ and VET compared to higher status adolescents. The results are examined in the context of adolescent emotional development.     

Perception of the cursive handwriting movement in writers and pre-writers

The objective of this study was to confirm the existence of knowledge relating to the cursive writing movement for French pupils in 3rd year of kindergarten, 2nd grade and 5th grade of elementary school. 141 pupils were asked to watch a visual presentation of cursive handwriting to determine whether they were able to detect violations of two rules of handwriting: continuity and sequentiality of the cursive handwriting movement. Our results showed progressive development of the understanding of characteristics of the cursive handwriting movement, with different developmental trajectories of knowledge for the different rules. The ability to detect continuity of the cursive writing movement developed earlier than the ability to detect sequentiality. Correct decisions were not always accompanied by correct justifications, which developed more slowly than detection of rule violations.     

How Do Young Children Misbehave in the Grocery Store and in the School? The Preschoolers' Perspective

This research assessed young children's perceptions about what misconduct behaviors peers are likely to commit across two contexts, the school and the grocery store. In addition, participants heard one of two versions in which the protagonist was either a boy or a girl. The participants were 70 preschool children (40 males and 30 females) and ranged in age from 36 to 77 months (M = 57 months). The results showed that a total of 242 non-repetitive behaviors were generated. Most of the behaviors generated either concerned acts having negative consequences to others (i.e., moral transgressions) or violations of social norms (i.e., conventional transgressions). The results also showed that children generated more moral than conventional misbehaviors. Moral acts were expected to occur more often in the school context than in grocery context, whereas social conventional misbehaviors were expected to occur in both contexts. Children described three specific types of moral misbehaviors: physical harm, property violations, and interpersonal violations. Furthermore, children's expectations of peers' misbehaviors were a function of the gender of the character committing the misdeed as well as the story context.     

GENDER DIFFERENCES IN THE INFLUENCE OF EARLY PERCEIVED PARENTAL SUPPORT ON STUDENT MATHEMATICS AND SCIENCE ACHIEVEMENT AND STEM CAREER ATTAINMENT

The lack of females entering STEM careers is well documented. Reasons for the gender gaps at all stages of the educational pipeline include both internal factors such as self-concept and external factors such as the influence of parents, media, and educators. Using latent growth curve analysis and nationally representative longitudinal survey data, this study compares differences in the relationship between a critical external factor (perceived early parental support), student mathematics and science achievement trajectories, and persistence in STEM career by gender. Mathematics and science trajectories were positively related to STEM career persistence for males and females. Perceived early parental support was related to growth in mathematics achievement for males but not females. There was no relationship between early perceived parental support and growth in science achievement for either males or females. These findings indicate differences in the relationship between parental support, achievement, and career persistence depending on content area and gender.     

Parent-child aggression,adult-partner violence,and child outcomes: A prospective,population-based study

Parent-child physical aggression (PCPA) and adult intimate partner violence (IPV) are common forms of family violence that often co-occur. Their deleterious effects on children and adolescents have been well documented. However, important questions remain regarding whether the type of violence exposure, the experience of one or both forms, the chronicity of violent experiences, and the age, gender, and SES of the child, differentially influence developmental outcomes. Data on 2810 children from the Project on Human Development in Chicago Neighborhoods were analyzed. Children aged 3–9 at the outset were assessed three times, at 3-year intervals. Primary caregivers reported on IPV, PCPA, and children’s externalizing and internalizing symptoms. Children’s externalizing and internalizing symptoms were examined as a function of time, age, gender, socioeconomic status (SES), and the time-varying effects of cumulative IPV and PCPA exposure. Cumulative experiences of IPV and PCPA each adversely affected the developmental trajectories of both externalizing and internalizing symptoms, but in different ways; and they did so independently of participants’ age, gender, or SES, which all functioned as significant, independent predictors of child outcomes. PCPA was by far the more potent of the two forms of violence; and when both forms occurred, they worked additively to affect outcomes. Important questions remain regarding the reasons for the differential potency of these two forms of family violence on childhood symptoms, and related implications for interventions, as well as for later adult behavior.     

The Evaluation of Student Fitness Levels in Exercise Science and Physical Education Teacher Education Programs

The debate on whether kinesiology students should undergo fitness testing is controversial. Some are strong proponents of fitness testing, while others are in strong opposition. As advocates for fitness testing among kinesiology majors, we aimed to assess the fitness levels of Exercise Science and Physical Education Teacher Education majors and evaluate current physical education teacher education (PETE) fitness criterion. One hundred and sixteen participants (males N = 49; females N = 67) underwent health-related fitness assessments. 37% of males and 51% of females met PETE’s fitness criteria. Both groups performed significantly better in body fat percentage and upper body strength than PETE’s acceptable (average) standards; however, most were significantly lower than target (above average) standards. Presented are fitness passing criteria for PETE majors and fitness reporting that aids in improved fitness tracking and accountability. We also highlight the need for NASPE and SHAPE America to clearly define fitness expectations for PETE majors and encourage other kinesiology faculty to consider implementing fitness testing in their programs.     

Parents do matter: trajectories of change in externalizing and internalizing problems in early adolescence

This study examined the relative influence of three parenting behaviors (support, behavioral control, and psychological control) and deviant peers on trajectories of externalizing and internalizing problems in early adolescence. A white, working-to-middle-class sample of adolescents and their mothers and fathers in two-earner families participated in a 32-year longitudinal study (N = 109 families). The study began when the adolescents were in sixth grade (M age = 11.5 years). Analyses showed that parents' firm behavioral control seemed to halt the upward trajectory in externalizing problems among adolescents with deviant peers. Initial levels of internalizing problems were higher among adolescents with parents who reported lower levels of behavioral control and among adolescents with deviant peers. This study suggests that parenting exerts an important influence in adolescents' lives and may do so even in the face of potentially negative peer influence.     

Trajectories of psychological need satisfaction from early to late adolescence as a predictor of adjustment in school

The present longitudinal study described developmental patterns of perceived psychological need satisfaction (PNS) from the end of elementary school to the end of high school and their contribution to school adjustment at the end of high school. The first goal thus consisted in estimating whether developmental trajectories of perceived PNS were homogeneous (i.e., all students reported similar developmental patterns) or heterogeneous (i.e., there were several distinct developmental trajectories). The second goal involved comparing trajectory groups on dimensions of school adjustment (social, academic, and emotional–personal). A stratified sample of 609 students (277 boys, 332 girls) was surveyed annually on a 6-year period, from the end of elementary school until the end of high school. Results of group-based trajectory modeling (Nagin, 1999, 2005) revealed that developmental trajectories of PNS were heterogeneous for autonomy, competence, and relatedness. For each need, four distinct developmental patterns were identified. These trajectories varied in shape, composition, and magnitude such that some students reported increasing PNS over time while others reported stable or decreasing PNS. Results from multivariate analyses revealed that students in upper trajectories (e.g., reporting higher levels of PNS, either stable or increasing) generally reported higher levels of academic, social, and personal–emotional adjustment at the end of high school. Results are discussed with respect to their implications for research and interventions.

An exploration of participative motivations in a community-based online English extensive reading contest with respect to gender difference

The purpose of this study is to describe an online community-based English extensive reading contest to investigate whether the participants’ intrinsic, extrinsic, and interpersonal motivations and learning results show significant gender differences. A total of 501 valid questionnaires (285 females and 216 males) from Taiwanese high school students and 15 interviewees from the students receiving awards were the subjects in this study. The findings show that females had a stronger participative intrinsic motivation, while males displayed a higher participative interpersonal motivation. Furthermore, female average scores were higher than the male ones on the comprehension tests. Even though the final results of the total scores for females were still higher than those of males, male scores for the interactivity tests were on average higher than those of females. The phenomena and implications behind the participative motivations are specifically discussed and explained.     

Achievement emotions and arithmetic fluency – Development and parallel processes during the early school years

This study investigated the developmental trajectories and interrelationships of mathematics-related achievement emotions and arithmetic fluency from first to third grade, and the effects of these on third grade mathematics performance. Participants were 232 Norwegian students. Students’ emotions and arithmetic fluency were measured four times and mathematics performance once. Applying latent growth curve modeling, developmental patterns of decreasing enjoyment and increasing boredom were observed over time. The mean level of enjoyment remained fairly high, and of both boredom and anxiety quite low. Individual differences were observed in both the initial levels and development of all emotions and arithmetic fluency, indicating differences in developmental trajectories. Only the initial levels and rate of change in arithmetic fluency predicted mathematics performance at the third grade.
