Endorsement of achievement goals across secondary school years: Applying a state-trait framework

This study examined stability and change in endorsement of achievement goals across secondary school years. A longitudinal, complementary, integrative approach was utilized with a sample of 6908 Korean eighth graders followed over three years at one-year intervals. The autoregressive models demonstrated differential stability, whereas latent growth curve models showed mean-level changes. Applying a state-trait framework, achievement goals evidenced both trait and state components; endorsement of achievement goals is stable, but may also exhibit change over time. Although all achievement goal types were more state-like than trait-like, avoidance goals (mastery-avoidance and performance-avoidance goals) were more malleable than approach goals (mastery-approach and performance-approach goals); no differences were found between approach or avoidance goals.     

Struggling to be liked: The prospective effect of trait self‐control on social desirability and the moderating role of agreeableness

Drawing from the literature on the interpersonal functions of self‐control, we examined longitudinal associations between trait self‐control and social desirability, using a survey of the general population in the Netherlands. Trait self‐control at baseline was positively associated with social desirability at a follow‐up, even when controlling for prior levels of social desirability. That is, high self‐control contributed to individuals' tendency to give socially desirable responses in self‐reports. This effect was moderated by individual differences in agreeableness. Highly agreeable individuals were more likely to “use” their self‐regulatory resources to respond in a socially desirable manner, compared to less agreeable individuals, suggesting that individuals might use self‐regulatory resources in a way consistent with the motivational bases of their personality.     

Cigarette smoking and personality change across adulthood: Findings from five longitudinal samples

Personality traits are related to cigarette smoking. However, little is known about the link between smoking and change in personality. Therefore, the present study examined whether current cigarette smoking and smoking cessation are associated with personality change across adulthood. Participants (n = 15,572) aged from 20 to 92 years were drawn from five longitudinal cohorts with follow-ups that ranged from 4 to 20 years. Compared to non-smokers, current smokers were more likely to increase on neuroticism and to decline on extraversion, openness, agreeableness and conscientiousness over time. Compared to the persistent smokers, those who quit had a steeper decline in agreeableness. Cigarette smoking is related to detrimental personality changes across adulthood, and the pattern was not improved by smoking cessation.     

Investigating the interplay between adolescent personality,parental control,and externalizing problem behavior across adolescence

This study explored transactional associations among adolescent personality (i.e., conscientiousness, agreeableness), parental control (i.e., proactive, punitive, psychological control), and externalizing problem behavior (i.e., aggressive or rule-breaking behavior). A three-wave longitudinal study across a two-year time span provided questionnaire data from 1,116 adolescents (M_age Wave 1 = 13.79, 51% boys), 841 mothers, and 724 fathers that was used in random intercept cross-lagged panel models. At the between-person level, adolescent personality, parental control, and externalizing problem behavior were significantly associated. Concerning the within-person level, conscientiousness showed reciprocal associations with externalizing problem behavior (negative), with agreeableness (positive) and punitive control (negative). Our findings observed a reciprocity between adolescent personality and externalizing problem behavior, but also suggest a role for parental control in this interplay.     

Individual differences in non-clinical maternal depression impact infant affect and behavior during the still-face paradigm across the first year

Maternal depression can significantly impact mothers’ sensitivity to their infants’ needs as well as infants’ social and emotional development. The still-face paradigm (SFP) is widely used to assess infants’ understanding of the contingency between their own behavior and that of their caregivers, as well as infants’ ability to self-regulate arousal levels during sudden changes in maternal responsiveness. Infants of clinically depressed mothers display blunted levels of negative affect compared to infants of non-depressed mothers during the still-face (SF) phase. However, little is known about whether individual differences in elevated, non-clinical levels of maternal depression similarly affect mother-infant interactions. The current study examines the longitudinal effects of non-clinical maternal depression on infant and maternal behaviors during the SFP. Infants (N = 63) were assessed at 5 and 9 months and maternal depression was assessed at 5 months using the Beck Depression Inventory (BDI). Infants of mothers with elevated levels of depression displayed less negative engagement during the SF phase compared to infants of mothers with lower levels of depression. This effect was present at 5 months, but not at 9 months. Findings demonstrate that non-clinical levels of maternal depressive symptomatology can have a significant impact on infants’ affective regulation during the first half of the first year of life, but this does not necessarily have a long-lasting influence later in infancy. Interventions may want to target mothers with non-clinical depression to promote healthy infant social and emotional development.     

Preterm birth enhances the contribution of mothers’ mind-mindedness to infants’ expressive language development: A longitudinal investigation

Maternal mind-mindedness has been shown to be a powerful predictor of many developmental outcomes and to buffer the impact of psychosocial risk conditions, but no study has investigated whether this parental feature might support child development in the presence of biological risk, such as preterm birth. The present study addresses this gap, by investigating whether early maternal mind-mindedness contributes to the growth of a child’s linguistic abilities in the following two years of life, and if the contribution of this maternal feature might be stronger in the presence of preterm birth. Forty mother–child dyads (twenty with a preterm infant) were followed longitudinally, with maternal mind-mindedness assessed at 14 months of age and child’s expressive linguistic abilities at 24 and 36 months through observational measures. Multilevel models showed that linguistic abilities increased from 24 to 36 months of age, but that this increase was stronger in full-term infants. Maternal mind-mindedness also contributed to this growth, playing a stronger role in preterm infants than in full-term infants. Altogether, these findings contribute more deeply to the understanding of language development in preterm infants and of the joint contribution made by biological risk and environmental factors; from a practical standpoint, they suggest the importance of addressing mother’s mind-mindedness in order to support child’s language development.     

Childhood antecedents of Agreeableness: A longitudinal study from preschool to late adolescence

Although the consensus view is that Agreeableness originates from childhood difficultness and regulatory deficits, few studies have investigated such assumptions longitudinally. In this study, we examined this issue by assessing enduring and mediating effects of self-regulation as well as the impact of parenting behaviors on the development of Agreeableness from preschool to late adolescence. Longitudinal data from 965 Norwegian families following children from 1.5 years to 16.5 years were used. Path analyses revealed childhood difficultness at age 4 to be related to Agreeableness at age 16.5; this effect was mediated through emotion regulation in late childhood. However, such mediation effects were primarily found when parents used punitive practices towards their children. Our findings point to personality coherence throughout development.     

Neuropsychological deficits in preschool as predictors of ADHD symptoms and academic achievement in late adolescence

High levels of ADHD symptoms are related to severe negative outcomes, which underscore the importance of identifying early markers of these behavior problems. The main aim of the present study was therefore to investigate whether neuropsychological deficits in preschool are related to later ADHD symptoms and academic achievement, over and above the influence of early ADHD symptom levels. The present study is unique because it includes a broader range of predictors compared to previous studies and the participants are followed over time for as long as 13 years (i.e., ages 5–18 years). Preschool data included measures of executive functioning and reaction time variability as well as emotional reactivity and emotion regulation of both positive and negative emotions. When controlling for early ADHD symptom levels, working memory, reaction time variability, and regulation of happiness/exuberance were significantly related to inattention whereas regulation of happiness/exuberance and anger reactivity were significantly related to hyperactivity/impulsivity. Furthermore, working memory and reaction time variability in preschool were significantly related to academic achievement in late adolescence beyond the influence of early ADHD symptoms. These findings could suggest that it is possible to screen for early neuropsychological deficits and thereby identify children who are at risk of negative outcomes. Furthermore, our results suggest that interventions need to look beyond executive functioning deficits in ADHD and also target the role of emotional functioning and reaction time variability. The importance of including both the positive and negative aspects of emotional functioning and distinguishing between emotion regulation and emotional reactivity was also demonstrated.
