Developmental personality types from childhood to adolescence: associations with parenting and adjustment

Friend influence and susceptibility to influence on emotions towards math: The role of adolescent temperament

BACKGROUND AND AIMS

Peer relationships during adolescence play an important role in shaping academic outcomes. The present study examined friend influences on emotions towards math, as well as the role of temperament in these influences.

SAMPLE

The sample consisted of 350 Finnish students (mean age 13.29 years; 64% girls) who were involved in stable friendship dyads from fall to spring of Grade 7.

METHODS

In this two-wave study, information on adolescents' temperament (i.e., negative emotionality, extraversion, effortful control) and on seven emotions towards math (i.e., enjoyment, hope, pride, anger, anxiety, shame, hopelessness, and boredom) was collected during grade 7. The data were analysed using longitudinal actor-partner interdependence models.

RESULTS

The results showed that friends resembled each other in all the investigated math-related emotions. Furthermore, over and above these initial similarities, friends mutually influenced each other's math-related enjoyment and anger towards math. Students characterized by higher negative emotionality also influenced their friends with lower levels of negative emotionality towards an increase in math-related anger and a lack of effortful control made adolescents more susceptible to friend influence over math-related shame and anxiety.

CONCLUSION

Our findings demonstrate that friends influence each other over time in math-related enjoyment and frustration. Furthermore, high negative emotionality may make adolescents more influential over their friends' math-related anger and a lack of effortful control may make adolescents more susceptible to friend influence over math-related shame and anxiety. Thus, the current findings have implications for how peer relations may impact individual outcomes in mathematics, for better or worse.

Patterns of Personality Development and Psychosocial Functioning in Japanese Adolescents: A Four-Wave Longitudinal Study

While patterns of adolescent personality development are country-specific, previous studies that have examined them have been limited to the Netherlands and Finland. This study aimed to identify the patterns of personality development and examine the relationship between these patterns and psychosocial functioning among Japanese adolescents. Overall, 618 Japanese adolescents (49.5% girls; 16 years) participated in the annual longitudinal survey from 2013 to 2016. Using latent class growth analysis, the following four patterns of personality development were identified: resilient, over-controlled, vulnerable, and moderate. Although the mean-level changes in the Big Five domains were generally insignificant among the four patterns, the vulnerable pattern showed a progressive increase in conscientiousness, and the moderate pattern showed a decrease in neuroticism and an increase in conscientiousness. Furthermore, multivariate analysis of variance tests indicated that the resilient pattern showed higher subjective well-being and lower psychosocial problems than the other personality patterns; the over-controlled pattern showed higher internalizing problems than the resilient pattern; the vulnerable pattern showed lower subjective well-being and higher internalizing problems than the other patterns; and the moderate pattern scored between the resilient, over-controlled, and vulnerable patterns in both subjective well-being and psychosocial problems. These findings suggest that the vulnerable and moderate patterns, which are immature patterns compared to the resilient and over-controlled ones, showed positive changes to the direction of maturity from middle to late adolescence in Japan.

Do stimulation and support in the early childhood home environment and best friendship quality in adolescence predict adult personality?

BACKGROUND

The aim of this study was to determine whether stimulation and support in early childhood and best friendship quality in adolescence predict adult personality.

PARTICIPANTS AND PROCEDURE

We used data from 123 individuals from an ongoing longitudinal study, with multiple assessment phases and modalities (observation, parental rating, self-report) to investigate prospective associations between stimulation and support in the home in early childhood (age 1-2), best friendship quality in adolescence (age 15), and the Big Five personality traits in adulthood (age 29) controlling for temperament, socioeconomic status (SES), and gender.

RESULTS

After controlling for temperament, SES, and gender, we found that early childhood stimulation and support was related to adult openness to experiences, but not the other four traits, and that best friendship quality in adolescence was related to adult extraversion and agreeableness, but not conscientiousness, neuroticism, or openness to experiences.

CONCLUSIONS

The study contributes to research indicating that while personalities are relatively stable, they are not fixed at an early age and may be related to experiences and salient relationships throughout development. There is a dearth of research investigating such associations and the available findings are inconsistent. Conclusions about the relations between experiences such as stimulation and support in the home in early childhood or best friendship quality in adolescence and adult personality should thus be viewed skeptically until replicated.

Maturation or disruption? Conscientiousness development in the transition into adolescence

Research to date has shown longitudinal changes in conscientiousness during early and middle adolescence, but most studies have been conducted in Western countries. The present study aimed to examine the pattern of mean-level conscientiousness change at the transition into early adolescence among a Chinese sample using curve of factors (CUFFS) models. Four waves of data from 661 Chinese children aged 8 years old at baseline in the China Family Panel Studies were used. Parents were asked to rate their children’s level of conscientiousness every 2 years. On average, mean-level conscientiousness showed a decelerating increase. Girls had higher average conscientiousness levels than boys, but they did not differ in change patterns. The inconsistency between the current study and previous research indicates that conscientiousness development may depend, in part, on cultural factors.

Resting-State Functional Connectivity Associated With Extraversion and Agreeableness in Adolescence

Although adolescence is a period in which developmental changes occur in brain connectivity, personality formation, and peer interaction, few studies have examined the neural correlates of personality dimensions related to social behavior within adolescent samples. The current study aims to investigate whether adolescents’ brain functional connectivity is associated with extraversion and agreeableness, personality dimensions linked to peer acceptance, social network size, and friendship quality. Considering sex-variant neural maturation in adolescence, we also examined sex-specific associations between personality and functional connectivity. Using resting-state functional magnetic resonance imaging (fMRI) data from a community sample of 70 adolescents aged 12–15, we examined associations between self-reported extraversion and agreeableness and seed-to-whole brain connectivity with the amygdala as a seed region of interest. Then, using 415 brain regions that correspond to 8 major brain networks and subcortex, we explored neural connectivity within brain networks and across the whole-brain. We conducted group-level multiple regression analyses with the regressors of extraversion, agreeableness, and their interactions with sex. Results demonstrated that amygdala connectivity with the postcentral gyrus, middle temporal gyrus, and the temporal pole is positively associated with extraversion in girls and negatively associated with extraversion in boys. Agreeableness was positively associated with amygdala connectivity with the middle occipital cortex and superior parietal cortex, in the same direction for boys and girls. Results of the whole-brain connectivity analysis revealed that the connectivity of the postcentral gyrus, located in the dorsal attention network, with regions in default mode network (DMN), salience/ventral attention network, and control network (CON) was associated with extraversion, with most connections showing positive associations in girls and negative associations in boys. For agreeableness, results of the within-network connectivity analysis showed that connections within the limbic network were positively associated with agreeableness in boys while negatively associated with or not associated with agreeableness in girls. Results suggest that intrinsic functional connectivity may contribute to adolescents’ individual differences in extraversion and agreeableness and highlights sex-specific neural connectivity patterns associated with the two personality dimensions. This study deepens our understanding of the neurobiological correlates of adolescent personality that may lead to different developmental trajectories of social experience.

Childhood Resilient Personality Trajectories and Associations with Developmental Trajectories of Behavioral, Social-emotional, and Academic Outcomes across Childhood and Adolescence: A Longitudinal Study Across 12 Years

This study examined the continuity and change of childhood resilient personality (first three years in grade school), and how differential trajectories in resilient personality were dynamically associated with behavioral problems, social-emotional functioning and academic performance across the primary and secondary school years (Grade 1-12). Participants were 784 academically at-risk students predominantly from low SES families (47% girls, 37.4% Latino or Hispanic, 34.1% European American, and 23.2% African American) who were recruited in grade 1 (Mean age = 6.57) and followed annually through the final year of high school (Grade 12). Results revealed three distinct trajectories of childhood resilient personality, including an ego-resilient or flexible group (26.8%), an ego-brittle or inflexible group (21.9%), and an ordinary or common group (49.9%). Children in the ego-brittle group were at a greater risk for sustaining high levels of behavioral problems, low socio-emotional functioning (based on parent and teacher report), and poor academic performance across formal schooling. In contrast, the resilient children exhibited persistently low behavioral problems, high social-emotional functioning, and better academic performance across formal schooling. Findings also indicated that the protective effect of childhood resiliency was sustained even after the transition from childhood to adolescence.

The Parent-Child Relationship and Posttreatment Child Outcomes Across Two Treatments for Oppositional Defiant Disorder

This study examined the degree to which the parent-child relationship uniquely predicted clinical outcomes in externalizing problems and adaptive skills in children meeting diagnostic criteria for oppositional defiant disorder and whether facets of this relationship moderated the effects of two unique psychosocial treatments. We recruited 134 children and their parents (38.06% female; M age = 9.52 years, range = 7-14; 83.58% White). Families were randomly assigned to 1 of 2 treatments: Parent Management Training (PMT) and Collaborative and Proactive Solutions (CPS). We formed principal components from pretreatment reports and behaviors of the parent-child relationship to predict within- and between-family outcomes in children's externalizing problems and adaptive skills. Four principal components were supported (parental warmth, parental monitoring, family hostility, and family permissiveness). Parental monitoring predicted fewer externalizing problems, whereas family permissiveness predicted more externalizing problems. Parental warmth predicted greatest improvements in children's adaptive skills among families receiving PMT. Family hostility predicted more externalizing problems and poorer adaptive skills for children; however, families receiving CPS were buffered from the negative effect of family hostility on adaptive skills. The parent-child relationship can uniquely inform posttreatment outcomes following treatment for oppositional defiant disorder. Certain treatment approaches may better fit unique relationships that emphasize warmth and/or hostility, allowing clinicians to anticipate and tailor treatments to families.

Does one Size Fit All?-Linking Parenting With Adolescent Substance Use and Adolescent Temperament

Using longitudinal Swedish data from 1,373 early-adolescent youths, this study aims to answer the question of whether the previously established protective function of parental knowledge and its sources-adolescent disclosure, parental solicitation, and parental control-on substance use among early-adolescents is moderated by the adolescent's temperament. Adolescent temperament moderated several links between parental knowledge and its sources and adolescent substance use. The most pronounced moderating results were found for those adolescents with fearless, socially detached and thrill-seeking tendencies. For these "detached thrill-seekers", bidirectional links between adolescent disclosure and substance use, and negative links between parental solicitation and substance use were found. We recommend, therefore, that adolescent temperament is considered when designing parenting programs.

The development of effortful control from late childhood to young adulthood

The present study investigated the developmental precursors of effortful control, a temperament trait that involves the propensity to regulate one's impulses and behaviors, to motivate the self toward a goal when there are conflicting desires, and to focus and shift attention easily. Data came from the California Families Project, a multimethod longitudinal study of 674 Mexican-origin youth (and their parents), who were assessed at ages 10, 12, 14, 16, and 19. Effortful control (measured via self- and parent-reports) was moderately stable over time (r = .47 from age 10 to 19), and its developmental trajectory followed a u-shaped pattern (decreasing from age 10 to 14, before increasing from age 14 to 19). Findings from latent growth curve models showed that youth who experience more hostility from their parents, associate more with deviant peers, attend more violent schools, live in more violent neighborhoods, and experience more ethnic discrimination tend to exhibit an exacerbated dip in effortful control. In contrast, youth with parents who closely monitor their behavior and whereabouts exhibited a shallower dip in effortful control. Analyses of the facets of effortful control revealed important disparities in their trajectories; specifically inhibitory control showed linear increases, attention control showed linear decreases, and activation control showed the same u-shaped trajectory as overall effortful control. Moreover, most of the precursors of effortful control replicated for inhibitory control and attention control, but not for activation control. We discuss the broader implications of the findings for adolescent personality development and self-regulation. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Bushmeat trade consequences predict higher anxiety, restraint, and dominance in chimpanzees

More data are needed for a better understanding of the long-term influence of wider and combined stressful events in chimpanzee personality development. We evaluated the effects of bushmeat trade outcomes on the personality development in 84 African sanctuary chimpanzees. The chimpanzees presented different backgrounds regarding maternal care, social exposure, and abuse. We evaluated personality traits in chimpanzees using the Cattell 16PF personality questionnaire, the first application of this questionnaire in this species. We found that chimpanzees were rated as higher in anxiety after long social deprivation during infancy and juvenility, and if high human exposure was experienced. Mother-reared chimpanzees were rated as lower in restraint than hand-reared chimpanzees. Finally, mother-reared chimpanzees were rated as less dominant than hand-reared chimpanzees and rated higher when they had experienced severe mistreatment. Results suggest a wide range of possible stressful events could be potentially shaping rescued chimpanzees' personality and demonstrating the detrimental outcomes and consequences of the bushmeat and pet trade.

Genetic and Environmental Associations Between Child Personality and Parenting

Parenting is often conceptualized in terms of its effects on offspring. However, children may also play an active role in influencing the parenting they receive. Simple correlations between parenting and child outcomes may be due to parent-to-child causation, child-to-parent causation, or some combination of the two. We use a multi-rater, genetically informative, large sample (n = 1411 twin sets) to gain traction on this issue as it relates to parental warmth and stress in the context of child Big Five personality. Considerable variance in parental warmth (27%) and stress (45%) was attributable to child genetic influences on parenting. Incorporating child Big Five personality into the model explained roughly half of this variance. This result is consistent with the hypothesis that parents mold their parenting in response to their child's personality. Residual heritability of parenting is likely due to child characteristics beyond the Big Five.

Adolescents' and mothers' temperament types and their roles in early adolescents' socioemotional functioning

The present study examined adolescents’ and mothers’ temperament types and their roles in the socioemotional functioning of early adolescents. A total of 869 sixth-grade students and 668 mothers participated in the study. The students rated their temperament and socioemotional functioning and the mothers rated their own temperament. Latent profile analyses identified four temperament types among the adolescents (resilient, reserved, average, and mixed) and three types among the mothers (resilient, average, and mixed). The results showed that the adolescents with resilient or reserved temperaments reported significantly fewer conduct problems and emotional symptoms, less hyperactivity, and higher prosociality than adolescents with a mixed temperament type. The most adaptive adolescent–mother temperament matches were between a resilient or reserved adolescent and a resilient or average mother; these adolescents reported the highest levels of socioemotional functioning. Mothers with mixed or average temperaments were related to fewer conduct problems and emotional symptoms and less hyperactivity among adolescents with a mixed temperament, while mothers with a resilient temperament type were beneficial for prosocial behavior among adolescents with a mixed temperament. These findings increase understanding of the role of temperament and the interplay between adolescents’ and mothers’ temperaments in the development of early adolescents’ socioemotional adjustment.

Using Group-Based Trajectory and Growth Mixture Modeling to Identify Classes of Change Trajectories

Many issues of interest to counseling psychologists involve questions regarding how individuals change over time. Although counseling psychologists often examine average levels of change, statistical methods can also identify patterns of change over time by empirically grouping together individuals with similar patterns of change (e.g., group-based trajectory modeling and latent growth mixture modeling). The purpose of this article is to provide an overview of these methods for counseling psychologists. We discuss the conceptual frameworks and assumptions of average-level and person-centered techniques such as group-based trajectory modeling and latent growth mixture modeling. We provide a nontechnical guide for conducting these analyses using data from a study of psychotherapy outcomes in a sample of mental health center clients ( N = 1,050). We discuss caveats associated with these methods, including the potential for overinterpreting nongeneralizable results. Last, we suggest best practices for reporting and interpreting results.

Personality trait change across late childhood to young adulthood: Evidence for nonlinearity and sex differences in change

We explored patterns of self-reported personality trait change across late childhood through young adulthood in a sample assessed up to 4 times on the lower-order facets of Positive Emotionality (PEM), Negative Emotionality (NEM), and Constraint (CON). Multilevel modeling analyses were used to describe both group- and individual-level change trajectories across this time span. There was evidence for nonlinear age-related change in most traits, and substantial individual differences in change for all traits. Gender differences were detected in the change trajectories for several facets of NEM and CON. Findings add to the literature on personality development by demonstrating robust nonlinear change in several traits across late childhood to young adulthood, as well as deviations from normative patterns of maturation at the earliest ages.
