Consistency and Change in Maternal Child-Rearing Practices and Values: A Longitudinal Study

Although developmental psychologists frequently assume that parents change their child-rearing practices as their children develop, there is little research on this topic and virtually none involving parents of adolescents and a longitudinal, repeated-measures design. We examined changes in mothers' reported practices over time in regard to independence and control, expression of positive and negative affect, and disciplinary practices using items from the Child-Rearing Practices Report (CRPR). The CRPR was administered to the same mothers 5 times over an 8-year time period (from when their children were aged 7 or 8 years until they were 15-16 years old). A substantial degree of stability in behaviors and values was noted, even over the 8-year period. In addition, some practices increased or decreased with age, with most of the changes being consistent with prior theorizing and research, as well as commonsense notions related to child rearing.     

Parent and Peer Predictors of Change in Attachment Security From Adolescence to Adulthood

Interview, self‐report, peer report, and observational data were used to examine parent and peer relationship qualities as predictors of relative changes in attachment security in a community sample of adolescents followed from ages 14 to 24. Early maternal supportive behavior predicted relative increases in attachment security from adolescence to adulthood, whereas psychological control and interparental hostile conflict predicted relative decreases. Peer predictors of relative increases in security included collaborative and autonomous behaviors and lack of hostile interactions, with peer predictions growing stronger for relationships assessed at later ages. Overall, models accounted for sufficient variance as to suggest that attachment security across this period is well explained by a combination of stability plus theoretically predicted change linked to social relationship qualities.     

Contributions of Reward Sensitivity to Ventral Striatum Activity Across Adolescence and Early Adulthood

It was examined how ventral striatum responses to rewards develop across adolescence and early adulthood and how individual differences in state‐ and trait‐level reward sensitivity are related to these changes. Participants (aged 8–29 years) were tested across three waves separated by 2 years (693 functional MRI scans) in an accelerated longitudinal design. The results confirmed an adolescent peak in reward‐related ventral striatum, specifically nucleus accumbens, activity. In early to mid‐adolescence, increases in reward activation were related to trait‐level reward drive. In mid‐adolescence to early adulthood decreases in reward activation were related to decreases in state‐level hedonic reward pleasure. This study demonstrates that state‐ and trait‐level reward sensitivity account for reward‐related ventral striatum activity in different phases of adolescence and early adulthood.     

Inhibitory Control During Emotional Distraction Across Adolescence and Early Adulthood

This study investigated the changing relation between emotion and inhibitory control during adolescence. One hundred participants between 11 and 25 years of age performed a go‐nogo task in which task‐relevant stimuli (letters) were presented at the center of large task‐irrelevant images depicting negative, positive, or neutral scenes selected from the International Affective Picture System. Longer reaction times for negative trials were found across all age groups, suggesting that negative but not positive emotional images captured attention across this age range. However, age differences in accuracy on inhibitory trials suggest that response inhibition is more readily disrupted by negative emotional distraction in early adolescence relative to late childhood, late adolescence, or early adulthood.     

Severe Violence During Adolescence and Early Adulthood and Its Relation to Anticipated Rewards and Costs

This report compares the effects (concurrent and lagged) of the anticipated rewards and costs of violent crime on engagement in severe violence in a sample of male juvenile offenders (N = 1,170; 42.1% black, 34.0% Hispanic, 19.2% white, and 4.6% other; ages 14–18 at baseline). Anticipated rewards (social approval, thrill) are more predictive of concurrent severe violence than are anticipated costs (social disapproval, risk of punishment). The analysis finds no evidence that perceptions of the rewards and costs of violent crime influence engagement in severe violence 6 months later. The results support the view that adolescence is a time of heightened reward salience but raise doubt about the longitudinal predictive validity of perceptions about crime during this time of life.     

The Motivational Landscape of Early Adolescence in the United States and China: A Longitudinal Investigation

This research examined motivational trajectories during early adolescence in the United States and China. Upon their entry into middle school at 7th grade and every 6 months thereafter until the end of 8th grade, 825 American and Chinese children (mean age = 12.73 years) reported on their motivational beliefs (e.g., mastery orientation) and behavior (e.g., self-regulated learning strategies). The quality of children's motivational beliefs deteriorated over the 7th and 8th grades (e.g., children became less mastery oriented) in both the United States and China. American children also valued academics less, with declines in their motivational behavior as well. Chinese children continued to value academics, sustaining their motivational behavior. In both countries, children's motivational beliefs and behavior predicted their grades over time.     

The Cascading Development of Autonomy and Relatedness From Adolescence to Adulthood

A developmental cascade model of autonomy and relatedness in the progression from parent to friend to romantic relationships across ages 13, 18, and 21 was examined among 184 adolescents (53% female, 58% Caucasian, 29% African American) recruited from a public middle school in Virginia. Parental psychological control at age 13 undermined the development of autonomy and relatedness, predicting relative decreases in autonomy and relatedness with friends between ages 13 and 18 and lower levels of autonomy and relatedness with partners at age 18. These cascade effects extended into adult friendships and romantic relationships, with autonomy and relatedness with romantic partners at age 18 being a strong predictor of autonomy and relatedness with both friends and partners at age 21.     

Exposure to Parental Depression in Adolescence and Risk for Metabolic Syndrome in Adulthood

The psychosocial consequences of living with a depressed parent have been well characterized. Less well known, however, is how this exposure is predictive of later physical health problems. The present study evaluated how parental depression across youths’ adolescence (ages 11–18) was associated with youth metabolic syndrome at age 25 (n = 391). Youth self-regulation and health behaviors were considered as possible moderators of the link between parental depression and youth metabolic syndrome. Analyses revealed that parental depression in adolescence was associated with a composite score reflecting metabolic syndrome components in early adulthood. Furthermore, self-regulation and health behaviors moderated this link, such that links between parental depression and the metabolic syndrome existed only for youth with low self-regulation or unhealthy behaviors.     

Continuity and Discontinuity in Perceptions of Family Relationships From Adolescence to Young Adulthood

The present 8‐year longitudinal study examined how multiple aspects of family relationships change across the transition from adolescence (M_age = 15 years) to young adulthood (M_age = 22 years) among 821 individuals. Results showed that there was more discontinuity than continuity in family relationships across this transition. Whereas a normative decline was evident in all measured aspects of family relationships during adolescence, this decline persisted for only a few dimensions of family relationships during young adulthood. Other aspects of family relationships stabilized or rebounded. There was little variation in these trajectories as a function of ethnicity or gender, suggesting that these changes in family relationships are generally normative. Results suggest that the transition to adulthood is a period of significant transformation in family relationships.     

A Six‐Year Longitudinal Study of Texting Trajectories During Adolescence

This study examined growth trajectories of texting (and other media) over a 6‐year time period. Participants were 425 adolescents from Washington, USA (age 13 at Time 1, age 18 at Time 6; 48% male, 68% European American). Analyses suggested a curvilinear pattern for texting and social media use, with rates peaking during midadolescence. There was also considerable heterogeneity in trajectories of texting. A growth mixture model revealed four distinct classes of individuals: perpetuals (14%), decreasers (7%), moderates (68%), and increasers (11%). Higher levels of depression, being a male, and coming from a single‐parent family predicted being a “perpetual” texter. Perpetuals had the most problematic outcomes compared to other classes, including higher depression, anxiety, aggression, and poor relationships with fathers.     

Socio-Economic Gradients and Disability During The Transition to Young Adulthood: A Longitudinal Survey and Register Study in Norway

The study aimed to investigate trends and explanatory factors for socio-economic inequalities associated with disability during the transition to young adulthood. A sample of 2606 participants (56% females and 44% males) was prospectively followed from adolescence to young adulthood. Disability status, age, gender, mental health problems, scholastic competence and social acceptance were measured from the longitudinal survey Young in Norway, while socio-economic indicators such as participants’ and their parents’ levels of education, annual income, unemployment and welfare benefits were extracted from the National Population Register in Norway. Regression models were applied to estimate associations between disability and socio-economic outcomes. The findings show that disabled adolescents have a significantly greater risk of achieving lower levels of education and are unemployed and over-represented in welfare benefits during the transition to young adulthood. Most of these associations between disability and socio-economic outcomes were explained by mental wellbeing and self-perceptions. The study suggests that interventions addressing mental wellbeing and social competence might reduce the development of socio-economic inequalities among young people with disability.     

Early Relationship Quality From Home to School: A Longitudinal Study

The aim of this investigation was to examine the role of social relationships in the home as predictors of social functioning in the first years of school. Longitudinal data gathered on 156 children from urban, low-income families were used to examine the unique contributions of mother-child attachment classification at ages 1 and 2 years, the child's relationship with another adult caregiver, the child's closeness to a sibling, and the child's status in the family relative to siblings between ages 3 and 4 years, to teacher reports of their own relationship to the child and the child's social skills in the classroom and peer relations. The role of family-based relationships as possible protective factors for children at social or demographic risk for problems in school was also tested. Results indicate that quality of different family relationships provides relatively independent and complementary information about early social functioning in school, with more limited evidence for compensatory or protective processes at work.

Sex Differences in School Science Performance from Middle Childhood to Early Adolescence

We investigated whether the sexes differ in science performance before they make important course and career selections. We collected teacher-report data from a sample of children from the Twins Early Development Study (TEDS) assessed at ages 9, 10 and 12 years (N>2500 pairs). In addition we developed a test of scientific enquiry and administered it to a sub-sample of TEDS (n=1135; age=14 years). We found no evidence for mean sex differences in science performance assessed by teachers, or by a test of scientific enquiry, although boys were somewhat more variable. At a time when adolescents are making important course choices, girls are performing just as well as boys.     

Stability of Core Language Skill from Early Childhood to Adolescence: A Latent Variable Approach

This four‐wave prospective longitudinal study evaluated stability of language in 324 children from early childhood to adolescence. Structural equation modeling supported loadings of multiple age‐appropriate multisource measures of child language on single‐factor core language skills at 20 months and 4, 10, and 14 years. Large stability coefficients (standardized indirect effect = .46) were obtained between language latent variables from early childhood to adolescence even when accounting for child nonverbal intelligence and social competence and maternal verbal intelligence, education, speech, and social desirability. Stability coefficients were similar for girls and boys. Stability of core language skill was stronger from 4 to 10 to 14 years than from 20 months to 4 years, so early intervention to improve lagging language is recommended.     

A Prospective Study of Life Stress, Social Support, and Adaptation in Early Adolescence

This study employed a 2-year longitudinal design to examine the relation of stressful life events and social supports to psychological distress and school performance among 166 early adolescents (mean age = 13.5 years). A prospective approach was utilized to control for initial levels of adjustment when examining the relation of Time 1 stress and support variables to Time 2 psychological distress and school performance. Both stress and support variables made significant contributions to the prediction of subsequent psychological distress. Stresses, but not supports, made a significant contribution to the prediction of subsequent school performance. Evidence for reciprocal and interactive linkages was also found, including effects of psychological distress and school performance on subsequent stresses and supports, and greater adaptive impact of school-based supportive resources under conditions of heightened risk outside of school. Implications for ecological and transactional models of development relating to the targeting and efficacy of preventive efforts are discussed.     

Genetic Change and Continuity from Fourteen to Twenty Months: The MacArthur Longitudinal Twin Study

Genetic change as well as continuity was investigated within the domains of temperament, emotion, and cognition/language for 200 pairs of twins assessed at 14 and 20 months of age in the laboratory and home. The second year of life is marked by change rather than continuity: correlations from 14 to 20 months averaged about .30 for observational measures of temperament and emotion, about .40 for language measures, and about .50 for mental development. 2 types of genetic change were examined: changes in the magnitude of genetic influence (heritability) and genetic contributions to change from 14 to 20 months. In general, heritability estimates were similar at 14 and 20 months. Evidence for genetic influence on change from 14 to 20 months emerged for several measures, implying that heritability cannot be equated with stability. Analyses of continuity indicated that genetic factors are largely responsible for continuity from 14 to 20 months.     

A Longitudinal Study of Forms and Functions of Aggressive Behavior in Early Childhood

The purpose of this study was to investigate the distinct forms (i.e., physical and relational) and functions (i.e., proactive and reactive) of aggressive behavior during early childhood ( n  =   101; M age = 45.09 months). Forms, but not functions, of aggressive behavior were stable over time. A number of contributors to aggression were associated with distinct subtypes of aggressive behavior. Females and socially dominant children were more relationally aggressive and older children were less physically aggressive than their peers. Longitudinal analyses indicated that social dominance predicted decreases in physical aggression and peer exclusion predicted increases in relational aggression. Overall, the results provide support for the distinction between subtypes of aggression in early childhood.     

Evaluating the Continuity of Offending from Adolescence to Emerging Adulthood and its Effect on Academic Failure among College Student Arrestees: A Research Note

Life-course/developmental criminology has generated a significant amount of research in recent years, yet some questions remained unanswered. The current study seeks to fill the gap in the literature by exploring two related research questions: (1) Are there identifiable factors that distinguish offenders who demonstrate continuity in their offending in adolescence and emerging adulthood? (2) Does offending continuity increase the likelihood for experiencing negative adult outcomes? Using official data from 1,920 college student arrestees, the results of this study suggest that males and violent offenders are significantly more likely to demonstrate offending continuity, and that offending continuity significantly increases the likelihood of academic failure in college (e.g. dropping out). Study limitations and implications are discussed.     

Personality Traits Are Associated With Cortical Development Across Adolescence: A Longitudinal Structural MRI Study

How personality traits relate to structural brain changes in development is an important but understudied question. In this study, cortical thickness (CT) and surface area (SA), estimated using magnetic resonance imaging (MRI), were investigated in 99 participants aged 8–19 years. Follow‐up MRI data were collected after on average 2.6 years for 74 individuals. The Big Five personality traits were related to longitudinal regional CT or SA development, but limited cross‐sectional relations were observed. Conscientiousness, emotional stability, and imagination were associated with more age‐expected cortical thinning over time. The results suggest that the substantial individual variability observed in personality traits may partly be explained by cortical maturation across adolescence, implying a developmental origin for personality–brain relations observed in adults.
