Stressful Events and Temperament Change during Early and Middle Adolescence: The TRAILS Study

This project investigates how stressful events are related to deviations from normative temperament development during adolescence. Temperament traits were assessed at ages 11 and 16 years. Life‐event data was captured using an interview (total n = 1197). Normative changes were found in all traits. A linear trend was found between the experience of stressful events and temperament development. Adolescents exposed to stressful events showed smaller decreases in fear and shyness, stronger decreases in effortful control and affiliation and smaller increases in high intensity pleasure. Exposure to stressful events was related to increases in frustration instead of decreases. Our results show that whereas normative development is mostly in the direction of maturation, adolescents who experienced stressful events showed less maturation of their temperament.

Serious,Minor, and Non-Delinquents in Early Adolescence: The Impact of Cumulative Risk and Promotive Factors. The TRAILS Study

This study uses a social-ecological approach to the development of delinquency. The authors emphasize that a balance between eliminating risk and enhancing protection across domains is essential in reducing problems and promoting competence. The cumulative risk and promotive effects of temperament, family and school factors in preadolescence were examined on different groups of delinquents (based on self-report) in early adolescence. Data from the first two waves of the TRAILS study (N = 2,230) were used. The results provide evidence for a compensatory model that assumes main effects of risk and promotive factors on problem behavior. Accumulation of risks in preadolescence promoted being a serious delinquent in early adolescence, with the strongest effects for temperament. Accumulation of promotive effects decreased being a delinquent and supported being a non-delinquent. Furthermore, evidence is found for a counter-balancing effect of cumulative promotive and risk factors. Exposure to more promotive domains in the relative absence of risk domains decreased the percentage of serious delinquents. Our results did not support a protective model. Implications for prevention and intervention are discussed.     

Early Developmental Precursors of Externalizing Behavior in Middle Childhood and Adolescence

This study examined the infancy- and toddler-age precursors of children's later externalizing problem behavior. Risk constructs included suboptimal patterns of observed caregiver-child interaction and the caregiver's perception of child difficultness and resistance to control. In addition, a novel dimension of caregiver-child relationship quality, the caregiver's perception of her toddler's unresponsiveness to her, was examined as a possible precursor of children's externalizing behavior. Externalizing problem outcomes were assessed throughout the school-age period and again at age 17, using multiple informants. As toddlers, children at risk for later externalizing behavior were perceived as difficult and resistant to control, and relationships with their caregivers were relatively low in warmth and affective enjoyment. Finally, the caregiver's perception of her toddler as emotionally unresponsive to her was a consistent predictor of later externalizing behavior, suggesting that negative maternal cognitions associated with child conduct problems may begin in toddlerhood. These predictive patterns were similar for boys and girls, and with minor exceptions, generalized across different subdimensions of externalizing problem behavior. Our findings underscore the importance of the infancy and toddler periods to children's long-term behavioral adjustment, and indicate the desirability of further research into the nature of caregivers' early perceptions of child unresponsiveness.     

Trajectories of Social Withdrawal from Middle Childhood to Early Adolescence

Heterogeneity and individual differences in the developmental course of social withdrawal were examined longitudinally in a community sample (N = 392). General Growth Mixture Modeling (GGMM) was used to identify distinct pathways of social withdrawal, differentiate valid subgroup trajectories, and examine factors that predicted change in trajectories within subgroups. Assessments of individual (social withdrawal), interactive (prosocial behavior), relationship (friendship involvement, stability and quality, best friend’s withdrawal and exclusion/victimization) and group- (exclusion/victimization) level characteristics were used to define growth trajectories from the final year of elementary school, across the transition to middle school, and then to the final year of middle school (fifth-to-eighth grades). Three distinct trajectory classes were identified: low stable, increasing, and decreasing. Peer exclusion, prosocial behavior, and mutual friendship involvement differentiated class membership. Friendlessness, friendship instability, and exclusion were significant predictors of social withdrawal for the increasing class, whereas lower levels of peer exclusion predicted a decrease in social withdrawal for the decreasing class.     

Predicting Early Sexual Activity with Behavior Problems Exhibited at School Entry and in Early Adolescence

Youth who initiate sexual intercourse in early adolescence (age 11–14) experience multiple risks, including concurrent adjustment problems and unsafe sexual practices. The current study tested two models describing the links between childhood precursors, early adolescent risk factors, and adolescent sexual activity: a cumulative model and a meditational model. A longitudinal sample of 694 boys and girls from four geographical locations was utilized, with data collected from kindergarten through high school. Structural equation models revealed that, irrespective of gender or race, high rates of aggressive disruptive behaviors and attention problems at school entry increased risk for a constellation of problem behaviors in middle school (school maladjustment, antisocial activity, and substance use) which, in turn, promoted the early initiation of sexual activity. Implications are discussed for developmental models of early sexual activity and for prevention programming.

Predicting ADHD Symptoms in Adolescence from Early Childhood Temperament Traits

Extreme levels of certain temperament traits can be early markers of different developmental pathways of attention-deficit/hyperactivity disorder (ADHD). However, the long-term utility of using these traits as predictors of ADHD is not fully known. This study includes 64 male adolescents (M age = 13.5), who have been followed since birth as part of a longitudinal study. The primary aim was to test effortful control (EC), activity level, and anger, measured in early childhood – both with mother’s reports and laboratory assessments –as predictors of ADHD symptoms in adolescence. Further, we investigated the specificity of this prediction to the different ADHD symptom domains. The results demonstrated that early temperament dimensions of EC and activity level were predictive of ADHD symptoms about 10 years later, when the participants reached adolescence. Moreover, activity level showed specificity only to hyperactivity-impulsivity symptoms whereas EC was a predictor of the two symptom domains. Anger had a predictive correlation with ADHD symptoms; however, it did not have a unique predictive contribution. These results emphasize the relevance of EC and activity level in the developmental course of ADHD. Identification of early risk factors can lead to more efficient design and implementation of intervention programs.     

The Development of Marijuana Dealing Behavior During Adolescence and Early Adulthood Among Juvenile Offenders: Risk Factors for Development

ABSTRACT

Despite the amount of attention paid to marijuana use, there has yet to be any research that examines heterogeneity in the development of marijuana dealing behavior across time. This research used group-based trajectory modeling to elucidate developmental trends in this behavior and examines how risk factors may predict heterogeneity in marijuana dealing among a sample of juvenile offenders. The Pathways to Desistance data set, a sample of 1,354 juvenile offenders followed across 84 months during adolescence and early adulthood following a recent adjudication, was utilized in analyses. Results indicate that a five-group model best fits the data. Results indicate that higher baseline resistance to peer influence was associated with increased risk of assignment to the Accelerating and High Chronic groups, whereas baseline marijuana use was associated with assignment to the Accelerating, Desisting, and High Chronic groups when all covariates were included in estimation. This indicates that juvenile offenders may be at risk for dealing marijuana during adolescence and use of the drug and low susceptibility to peer influence may indicate higher risk for engagement.     

Risk Factors for Disordered Eating During Early and Middle Adolescence: A Two Year Longitudinal Study of Mainland Chinese Boys and Girls

Even though reliable eating disorder risk factors have been identified among adolescent girls, little is known about predictors of increased vulnerability within specific phases of adolescence or among adolescent boys, particularly in highly populated non-Western contexts. In this study, early and middle adolescent boys (n?=?1,271) and girls (n?=?1,415) from Chongqing, China completed validated measures of eating disorder pathology and putative risk factors at baseline and 2 years follow-up. Multivariate models for boys of each age group indicated increases in disordered eating at follow-up were predicted by higher initial body mass index, negative affect and body dissatisfaction levels as well as attendant increases in perceived appearance pressure from mass media, body dissatisfaction, negative affect between assessments. High baseline levels of reported appearance pressure from parents and dating partners contributed, respectively, to prediction models of younger and older boys. More distinct constellations of significant predictors emerged in multivariate models of early versus middle adolescent girls. Together, findings indicated body dissatisfaction and negative affect were fairly robust risk factors for exacerbations in disturbances across samples while risk factors such as perceived pressure from desired/prospective dating partners were salient only during particular phases of adolescence.     

Linking Executive Function and Peer Problems from Early Childhood Through Middle Adolescence

Peer interactions and executive function play central roles in the development of healthy children, as peer problems have been indicative of lower cognitive competencies such as self-regulatory behavior and poor executive function has been indicative of problem behaviors and social dysfunction. However, few studies have focused on the relation between peer interactions and executive function and the underlying mechanisms that may create this link. Using a national sample (n?=?1164, 48.6 % female) from the Study of Early Child Care and Youth Development (SECCYD), we analyzed executive function and peer problems (including victimization and rejection) across three waves within each domain (executive function or peer problems), beginning in early childhood and ending in middle adolescence. Executive function was measured as a multi-method, multi-informant composite including reports from parents on the Children’s Behavior Questionnaire and Child Behavior Checklist and child’s performance on behavioral tasks including the Continuous Performance Task, Woodcock-Johnson, Tower of Hanoi, Operation Span Task, Stroop, and Tower of London. Peer problems were measured as a multi-informant composite including self, teacher, and afterschool caregiver reports on multiple peer-relationship scales. Using a cross-lagged design, our Structural Equation Modeling findings suggested that experiencing peer problems contributed to lower executive function later in childhood and better executive function reduced the likelihood of experiencing peer problems later in childhood and middle adolescence, although these relations weakened as a child moves into adolescence. The results highlight that peer relationships are involved in the development of strengths and deficits in executive function and vice versa.     

Peer Substance Use and Homelessness Predicting Substance Abuse from Adolescence Through Early Adulthood

Adolescents who experience homelessness are at higher risk for abusing substances, and for being exposed to substance-using peers. The current study used a longitudinal design to track substance abuse, affiliation with substance-using peers, and episodes of homelessness among a sample of 223 adolescents who were housed at the baseline data collection and 148 adolescents who were housed at baseline. Participants were interviewed at six waves over 6.5 years, covering an age range from 13 to 25. Many participants experienced a recurrence of homelessness during follow-up, with 64.6 % of the baseline homeless group and 22.6 % of the baseline housed group reporting an additional episode of homelessness. Both alcohol abuse and other drug abuse symptoms showed an increase in adolescence followed by slowing in early adulthood. Recent homelessness and friend alcohol use predicted alcohol abuse symptoms, and the strength of the influence of friend use decreased over time. Recent homelessness and friend drug use predicted other drug abuse symptoms. Duration of the initial episode of adolescent homelessness showed no influence on substance abuse over time, or the effects of other predictors, highlighting the importance of conceptualizing the experience of homelessness as a recent stressor rather than an enduring personal characteristic.     

Middle School Friendships and Academic Achievement in Early Adolescence: A Longitudinal Analysis

Early adolescence is a critical transition period for the maintenance of academic achievement. One factor that school systems often fail to take into account is the influence of friends on academic achievement during middle school. This study investigated the influence of friends' characteristics on change in academic achievement from Grade 6 through 8, and the role of students' own characteristics as moderators of this relationship. The sample included 1,278 participants (698 girls). Linear regressions suggest that students with academically engaged friends may achieve to levels higher than expected in Grade 8. However, when considering the significant, negative influence of friends' problem behavior, the role of friend's school engagement became nonsignificant. Low-achieving girls who had high-achieving friends in Grade 6 had lower academic achievement than expected by Grade 8. In contrast, high-achieving girls seemed to benefit from having high-achieving friends. Implications for theory and prevention efforts targeting young adolescents are discussed.     

Child Characteristics,Parent Education and Depressive Symptoms,and Marital Conflict Predicting Trajectories of Parenting Behavior from Childhood Through Early Adolescence in Taiwan

The study examined how child and parent characteristics, and contextual sources of stress, such as marital conflict predict initial status and trajectories of parent involvement, support, and harsh control, over a 4‐year period in families in Taiwan (n = 4,754). Based on Belsky's (1984) ecological model of parenting, three domains predicting parenting were tested, child characteristics (age cohort and gender), father and mother characteristics (education and depressive symptoms), and contextual sources of stress (marital conflict). The study followed two cohorts of children; the younger cohort was followed from first to fourth grade and the older cohort from fourth to seventh grade. Initially, fourth graders reported more parental involvement, support, and harsh control than first graders. However, involvement, support, and harsh control decreased across the 4 years for the older cohort as they transitioned to early adolescence. In the first year, girls reported more parental involvement and support and less harsh control than boys. Across the 4 years, involvement and support increased, and harsh control decreased for boys; whereas involvement stayed the same, support slightly decreased, and harsh control slightly increased for girls. Children whose parents were more educated reported more parent involvement, support, and harsh control in the first year. Children whose fathers were chronically depressed and whose parents were experiencing marital conflict reported decreasing parent involvement and support over the years.     

童年晚期至青少年早期攻击和同伴侵害的关系:交叉滞后研究

采用整群抽样法抽取2178名小学生为被试（平均年龄11.05±0.69岁,男生1132人）自5年级追踪至8年级,通过纵向交叉滞后模型对攻击与同伴侵害间的关系进行考察。结果发现,各年级关系攻击均可预测之后的关系侵害,7年级身体攻击预测8年级身体侵害,此外6年级关系侵害经历对7年级关系攻击具有预测作用。攻击与同伴侵害间的纵向联系不存在性别差异。这些结果表明,童年晚期至青少年早期攻击与同伴侵害之间总体上符合连续性社交过程模型,即攻击对随后的同伴侵害具有更明显预测作用,但在小学升初中的学校过渡阶段关系侵害预测随后的关系攻击,部分支持两者间存在双向关系。该结果提示需关注儿童青少年的攻击与同伴侵害经历,采取措施避免其陷入攻击与同伴侵害间的恶性循环之中。     

情绪调节效应的发展:一个V型发展趋势

从青少年早期到成人早期,个体情绪调节等高级社会认知功能得到进一步完善,对情绪调节的需求也日趋增长。情绪调节的发展是青少年情绪社会化发展一个重要的任务,学会采用有效的调节策略对自身情绪进行调节是青少年社会性发展的一个重要表现。在众多关于青少年社会行为研究中,对负性情绪调节能力的探究最为成熟与深入。以往研究指出,儿童青少年对负性情绪的体验激活和调控失败都是导致其非适应性行为的原因,情绪调节方式的错误选择会与其外化行为问题和和内化行为问题有很大的关联。由于青少年适应性行为的习得是多种社会性发展指标的重叠和交叉作用的体现,我们无法完全理清其中的复杂交互作用,因此从情绪调节策略的使用效应发展入手探讨个体的适应是寻求问题解决的一个可行手段。 以往研究者认为,成熟且有效的情绪调节指的是,个体能够通过控制自身的激活和唤醒以达到情绪性、生理性和社交的适应,最后达成个人的目标。情绪调节的发展也可被看作是从被动式的、有他人参与的调节（例如,社会性参照）逐渐进步为主动的、有意识的根据外部线索进行的情绪调节（例如,根据指导语提示调整自己情绪状态）。 本研究旨在探究不同年龄被试（青少年早期、青少年晚期、成人早期）在按照不同指导语提示要求下增强调节和减弱调节调节效应量的年龄差异。选取上海市初中生被试35名（22男,13女;M = 14.06岁,SD = 0.42 岁, 年龄范围：13-15岁）、高中生被试37名（13男,24女;M=16.56岁, SD=0.56岁, 年龄范围：16-18岁）以及成人被试35名（9男,26女;M = 23.60岁,SD = 1.96岁, 年龄范围：20-29岁）,采用3（年龄：初中生、高中生、成人,被试间变量）? 3（情绪刺激：正性、中性、负性,被试内变量）? 3（调节策略：增强调节、减弱调节、不调节,被试内变量）混合实验设计,使用情绪反应性—调节图片任务（Reactivity and Regulation-Image Task,REAR-I Task）对不同年龄被试情绪调节策略使用的效应量进行考察（Carthy, Horesh, Apter, Edge, & Gross, 2010）。 研究发现,从总体趋势来说,情绪调节策略的效应发展呈V型发展趋势。当不同年龄被试按照指导语要求对其情绪体验进行主动调节时,成人被试的调节效应是最大的,初中生次之,而高中生的调节效应则最低。情绪调节的V型发展趋势与以往研究中关于情绪调节态度以及自我发展的趋势相一致。另外,与增强调节策略的使用相比,减弱调节策略效应的发展是最大的。这可能与中国背景下减弱调节的适应价值有关。     

The Network Constellation of Personality and Substance Use: Evolution from Early to Late Adolescence

There is a well-established link between substance use and four personality traits of anxiety–sensitivity, hopelessness, impulsivity, and sensation-seeking. However, construct-level models of personality may conceal indicator-level personality–outcome associations. The current study aims to investigate evolution of the network constellation of personality and cannabis/alcohol use from early to late adolescence. Data comes from the longitudinal Co-Venture cohort (N = 3800). Personality indicators, measured by Substance Use Risk Profile Scale (SURPS) items, and the frequency of cannabis/alcohol use were assessed at four consecutive years (13–17 years old). Network constellations of the SURPS items and cannabis/alcohol use were estimated using Bayesian Gaussian graphical models at four time points. Results highlighted the age-specific associations between personality indicators and substance use. The positive role of the sensation-seeking trait (e.g. attitude towards transgression) was constant, whereas the positive role of hopelessness indicators (e.g. not being enthusiastic about future) and the negative role of anxiety–sensitivity indicators (e.g. fear of having unusual body sensations) were more prominent at early adolescence. The current study provides a novel perspective on the network structure of personality and substance use in adolescence and suggests substance-specific and age-adjusted targets in intervention efforts. © 2020 European Association of Personality Psychology     

Effects of Multiple Maternal Relationship Transitions on Offspring Antisocial Behavior in Childhood and Adolescence: A Cousin-Comparison Analysis

Previous studies of the association between multiple parental relationship transitions (i.e., when a parent begins or terminates an intimate relationship involving cohabitation) and offspring antisocial behavior have varied in their efforts to rule out confounding influences, such as parental antisocial behavior and low income. They also have been limited in the representativeness of their samples. Thus, it remains unclear to what degree parents’ multiple relationship transitions have independent effects on children’s antisocial behavior. Analyses were conducted using data on 8,652 6–9-year-old, 6,911 10–13-year-old, and 6,495 14–17-year-old offspring of a nationally representative sample of U.S. women. Cousin-comparisons were used in combination with statistical covariates to evaluate the associations between maternal relationship transitions and offspring antisocial behavior in childhood and adolescence. Cousin-comparisons suggested that associations between maternal relationship transitions and antisocial behavior in childhood and early adolescence are largely explained by confounding factors. In contrast, the associations between maternal relationship transitions and offspring delinquency in late adolescence were robust to measured and unmeasured confounds. The present findings suggest that interventions aimed at reducing exposure to parental relationship transitions or addressing the psychosocial consequences of exposure to parental relationship transitions could reduce risk for offspring delinquency in late adolescence.     

Links Between Perception of Parental Actions and Prosocial Behavior in Early Adolescence

We analyzed the links between parental styles, practices, and empathy and specific forms of prosocial behaviors in early adolescence. The Argentine scale of perception of relationships with parents for children and young adolescents, prosocial tendencies measure, parenting practices measure, and children’s perception of parental empathy were administered to a sample of 289 middle class children, aged 10–16, of both sexes, from primary and secondary schools in Buenos Aires, Argentina. Correlations and hierarchical regressions were used to examine (1) relationships between parental styles, children’s perception of parental empathy, parental practices, and children’s prosocial behavior, (2) the amount of unique prediction from parental styles, children’s perception of parental empathy, and parental practices to children’s prosocial behavior. Results indicated that different aspects of parental actions (parental styles, practice, and empathy) have a differential relation according to the type of prosocial behavior involved. When taking these three kinds of parental behavior into account, parental styles are related to public and responsive aspects especially through extreme control by the mother. Parental practices, in turn, are related mainly with anonymous and altruistic aspects, but with this latter negatively. Finally, adolescents’ perception of parental empathy explains added variance in all the cases, though to a lesser extent.     

Planned Versus Unplanned Risks: Evidence for Subtypes of Risk Behavior in Adolescence

Risk behavior escalates during adolescence, contributing to substantial morbidity and mortality. This study examined whether individual differences in personality and neurocognitive function previously shown to be associated with overall frequency of risk behavior are differentially related to two proposed subtypes of adolescent risk behavior: planned and unplanned. Adolescents (N = 69, 49% male, M = 15.1 years, SD = 1.0), completed a battery of self-report measures and neurocognitive tasks. Several personality and neurocognitive variables predicted membership in the planned versus unplanned risk group: perceiving the benefits of risk behaviors to outweigh risks, more accurately identifying beneficial choices in a modified Iowa Gambling Task (IGT), and performing more advantageously on the IGT and the Game of Dice Task. This study supports the hypothesis that planned versus unplanned risk behavior comprise distinct subtypes in adolescence. Understanding the mechanisms underlying these subtypes may inform prevention programs targeting specific contributors to adolescent risk behavior.
