Pathways of peer relationships from childhood to young adulthood

This study examined trajectories of peer social preference during childhood and personality assessed in early adolescence in relation to trajectories of friendship quality during early adulthood. Participants (N = 585) were followed from ages 5 to age 23. At ages 5 to 8, peers provided sociometric nominations; at age 12 participants reported their own personality characteristics; from ages 19 to 23 participants rated their friendship quality. Latent growth modeling revealed that trajectories characterized by high levels of childhood peer social preference were related to trajectories characterized by high levels of early adulthood friendship quality. Early adolescent personality characterized by extraversion and conscientiousness predicted higher friendship quality at age 19, and conscientiousness predicted change in friendship quality from ages 19 to 23. This study demonstrates that peer relationships show continuity from childhood to early adulthood and that qualities of core personality are linked to the development of adult friendships.     

Gendered personality disposition and gender role attitudes among Israeli students

In a sample of 204 Israeli university students, the author examined the relationship between gendered personality dispositions and 2 aspects of gender role attitudes: occupational sex typing and gender role stereotypes. Evaluations of occupational gender attributes were the least sex typed among participants in the androgynous group. At the same time, contrary to expectations, the participants in the undifferentiated and sex-typed groups had relatively stereotyped perceptions of occupations. However, no relationship was found between gendered personality disposition and stereotyped perceptions of gender roles. Regardless of gendered personality disposition, the women, compared with the men, had more liberal attitudes toward gender roles.     

Personality Traits Elucidate Sex Differences in Attention-Deficit/Hyperactivity Disorder Comorbidity During Early Childhood

Attention-Deficit/Hyperactivity Disorder (ADHD) is highly comorbid with other childhood disorders, and there are striking sex differences in this comorbidity, particularly during early childhood. For example, boys with ADHD are more likely to exhibit comorbid disruptive behavior and neurodevelopmental disorders, compared to girls, during early childhood. Yet, explanations for these well-established sex differences remain in short supply. The current study evaluated the novel hypothesis that personality traits may serve as intermediate phenotypes that help explain sex differences in common ADHD comorbidity profiles during early childhood. Study participants were 109 children between the ages of 3 and 6 and their primary caregivers and teachers/daycare providers, recruited from the community and over-recruited for ADHD-related problems. Primary caregivers completed the Child Behavior Checklist, and teachers/daycare providers completed the Teacher Report Form as a measure of child behavior problems. Examiners completed the California Q-Sort as a measure of child personality traits. Moderated mediation analyses suggested that personality traits explain associations between ADHD and oppositional-defiance, aggression, and language problems in a sex-specific manner. While high neuroticism mediated associations between ADHD and oppositional-defiance in girls, disagreeableness mediated associations between ADHD and aggression and low conscientiousness mediated associations between ADHD and neurodevelopmental language problems in boys. Sex differences in trait-psychopathology associations may help explain sex differences in comorbidity profiles with possible implications for child assessment and personalized early intervention.

Abstract

In a sample of 204 Israeli university students, the author examined the relationship between gendered personality dispositions and 2 aspects of gender role attitudes: occupational sex typing and gender role stereotypes. Evaluations of occupational gender attributes were the least sex typed among participants in the androgynous group. At the same time, contrary to expectations, the participants in the undifferentiated and sex-typed groups had relatively stereotyped perceptions of occupations. However, no relationship was found between gendered personality disposition and stereotyped perceptions of gender roles. Regardless of gendered personality disposition, the women, compared with the men, had more liberal attitudes toward gender roles.     

Mechanisms by Which Childhood Personality Traits Influence Adult Well-Being

ABSTRACT— Children's personality traits have enduring effects that shape adult well-being. In particular, childhood conscientiousness influences core aspects of adult well-being: health, friendships, and mastery. Research is now examining the mechanisms by which early personality traits initiate and sustain particular life paths. These include mediating and moderating mechanisms that may operate during critical developmental periods or may build cumulatively over time. Future research would benefit from testing theoretically derived mechanisms for different traits and examining variables as they change over time, using both short- and long-term longitudinal designs over different life stages.     

How our work influences who we are: Testing a theory of vocational and personality development over fifty years

This study examines the developmental influences of occupational environments on personality traits from childhood to adulthood. We test aspects of a theory of vocational and personality development, proposing that traits develop in response to work experience following corresponsive and noncorresponsive mechanisms. We describe these pathways in the context of situations of vocational gravitation and inhabitation. In a sample from the Hawaii personality and health cohort (N = 596), we examined associations of childhood and adulthood personality traits, with occupational environments profiled on the RIASEC model. Mediations tests confirmed that work influenced personality development from childhood to adulthood for Openness/Intellect. We observed multiple reactivity effects of occupation environments on adulthood traits that were not associated with corresponding selection effects.     

The Westermarck Effect and early childhood co‐socialization: Sex differences in inbreeding‐avoidance

The aim of this study was to determine whether there are sex differences in regard to the effect of early childhood co‐socialization on inbreeding‐avoidance at sexual maturity. Multiple logistic regression methodology was used to model the relationship between cousin relationship and social proximity in childhood and its effect on mate choice beyond adolescence for a sample of Moroccan participants. Females showed a synergistic interaction effect for cousin marriage and childhood co‐socialization and an additional interaction effect for co‐socialization during the first seven years of childhood. Male participants showed no significant effect for early childhood co‐socialization. The Westermarck Effect hypothesis that early childhood co‐socialization leads to a lack of sexual interest at maturity is thus supported for female participants but not for male participants. These results are consistent with expectations from parental investment theory that females should show greater inbreeding‐avoidance than males do because of the greater costs females suffer as a consequence of inbreeding depression.     

The association between persistent disruptive childhood behaviour and the psychopathic personality constellation in adolescence: A twin study

This study tested if persistent externalizing behaviour and symptoms of Attention Deficit Hyperactivity Disorder (ADHD) in childhood are associated with personality and behavioural aspects of the psychopathic personality constellation in adolescence. The target sample consisted of all 1,480 twin pairs born in Sweden between 1985 and 1986. Parent‐reported externalizing behaviour and ADHD symptoms were obtained when the participants were 8–9 and 13–14 years old. Personality and behavioural aspects of the psychopathic personality constellation were measured with self‐report questionnaires when the participants were 16–17 years old. Persistent externalizing behaviour in childhood was associated with both psychopathic personality and antisocial behaviour in adolescence. However, within twin‐pair analyses showed that genetic factors explained the association between persistent externalizing behaviour and psychopathic personality, while shared environmental factors explained the association between persistent externalizing and antisocial behaviours. We conclude that persistent externalizing behaviour is a genetically influenced precursor of psychopathic personality among boys.

Adolescent substance use disorders: findings from a 14-year follow-up of speech/language-impaired and control children.

Intervening on the development of adolescent addiction requires an understanding of the role of precursors. In a community sample of youth with and without early childhood speech/language (S/L) impairments, 12.7% of participants had a substance use disorder (SUD). Among these participants, 42.0% met criteria for more than 1 SUD. Interestingly, rates of SUDs did not differ by S/L status. However, S/L-impaired participants did show greater psychiatric comorbidity and poorer functioning. A total of 80% of S/L participants with SUDs had a concurrent diagnosis of antisocial personality disorder, compared with 43.8% of SUDs controls. In a logistic regression analysis, we found age 5 mother-rated problem behavior scores and an interaction between S/L status and teacher-rated conduct problem scores were predictive of SUDs. High conduct scores were predictive of SUDs development among control participants but not among S/L-impaired participants. First substance use and initial SUDs symptoms suggest that a window of opportunity exists to reach these troubled young people before they spiral into addiction.     

The relationship between childhood abuse and adult personality disorder symptoms

This study assessed personality disorder symptomatology in a community sample of healthy adults without diagnosable DSM-IV-TR Axis I psychiatric disorders who reported a history of childhood abuse. Twenty-eight subjects with a history of moderate to severe physical, sexual, and/or emotional abuse according to the Childhood Trauma Questionnaire were compared to 33 subjects without an abuse history on symptoms of personality disorders. Subjects in the Abuse group were more likely to report subclinical symptoms of paranoid, narcissistic, borderline, antisocial, obsessive compulsive, passive-aggressive, and depressive personality disorders. These findings link reports of childhood abuse with symptoms of personality disorders in the absence of Axis I psychiatric disorders in a community sample of healthy adults.     

The emergence, structure and development of ethnic identity during childhood: the case of Roma identity

This study investigates the emergence, development and structure of ethnic identity during childhood. Forty Roma children living in Greece aged between 2.8 and 11.9 years answered questions about their awareness/recognition of four aspects of their ethnic identity-namely place of habitation, traditional costumes, the Roma language, and early betrothal of children-their identity and their sense of stability and constancy. The study also investigates how the children feel about the abandonment of those four aspects. The evidence from the current data supports the hypothesis that awareness of ethnic identity emerges before the age of 4. Moreover, this study offers direct empirical evidence of the multidimensionality of ethnic identity. A model of three concentric rings is proposed, extending from a core containing the most highly valued aspects of ethnic identity to the outer annulus that comprises the nonpermanent and nonstable aspects of ethnic identity. The aspects in each annulus differ in terms of the development of the sense of stability and constancy and the feelings associated with loss of the aspects in question. Even the youngest participants considered the aspects in the core to be stable and constant as well as emotionally charged; and even the 11-year-olds did not consider the aspects contained in the outer, more fluid annulus as stable and constant aspects of their ethnic identity. The development of an aspect is determined by what the majority of adults in a society, at a particular time in history, consider to be most important.
