Predicting educational achievement from genomic measures and socioeconomic status

The two best predictors of children's educational achievement available from birth are parents’ socioeconomic status (SES) and, recently, children's inherited DNA differences that can be aggregated in genome‐wide polygenic scores (GPS). Here, we chart for the first time the developmental interplay between these two predictors of educational achievement at ages 7, 11, 14 and 16 in a sample of almost 5,000 UK school children. We show that the prediction of educational achievement from both GPS and SES increases steadily throughout the school years. Using latent growth curve models, we find that GPS and SES not only predict educational achievement in the first grade but they also account for systematic changes in achievement across the school years. At the end of compulsory education at age 16, GPS and SES, respectively, predict 14% and 23% of the variance of educational achievement. Analyses of the extremes of GPS and SES highlight their influence and interplay: In children who have high GPS and come from high SES families, 77% go to university, whereas 21% of children with low GPS and from low SES backgrounds attend university. We find that the associations of GPS and SES with educational achievement are primarily additive, suggesting that their joint influence is particularly dramatic for children at the extreme ends of the distribution.     

Cognition and the development of temperament from late childhood to early adolescence

Temperament is related to cognition, but it is unclear whether reciprocal associations exist with early developmental trajectories. Children from the Longitudinal Study of Australian Children (N = 8,677) were assessed over four waves on verbal ability at ages 8/9, nonverbal ability at ages 8/9 and 10/11, and parent-rated temperament every two years from ages 8/9 to 14/15. Latent difference score analyses indicated correlated changes between ages 8/9 and 10/11. Increased nonverbal ability over the first two years was associated with declined reactivity and increased persistence. Latent growth curve models further indicated that nonverbal and verbal ability at baseline were associated with declined reactivity and increased persistence over the six years. These findings suggest bidirectional associations between childhood cognitive ability and temperament development.     

Transactional development of parent personality and child temperament

Stability and change in parental extraversion and neuroticism were studied in transaction with their views of their child's temperament from the age of six months to the age of five‐and‐a‐half years in 109 mother–father–child triads (parent–daughter: n = 61, parent–son: n = 48). While parental traits showed high stability, infants' higher positive affectivity predicted an increase in parental extraversion over 5 years, and infant's higher activity predicted a decrease in parental neuroticism. Parent‐rated temperament showed expected heterotypic continuity. Initially higher parental extraversion predicted an increase in the child's effortful control, and higher parental neuroticism predicted an increase in the child's negative affectivity. The results indicate that parental personality and child temperament develop in transaction promoting change in each other. Copyright © 2008 John Wiley & Sons, Ltd.     

Associations of self‐esteem and temperament traits to self‐ and teacher‐reported social status among classmates

Hintsanen, M., Alatupa, S., Pullmann, H., Hirstiö‐Snellman, P. & Keltikangas‐Järvinen, L. (2010). Associations of self‐esteem and temperament traits to self‐ and teacher‐reported social status among classmates. Scandinavian Journal of Psychology 51, 488–494. The present study examined the validity of self‐ and teacher‐reported social status and its relations to self‐esteem and temperament in a geographically representative cohort of Finnish adolescents (N = 3941, mean age 15.1 years). High agreement was found between self‐ and teacher‐rated social status (r = 0.42). Different aspects of self‐esteem were differently related to social status. When other temperament and self‐esteem variables were included in the analyses, strongest predictor for self‐rated social status in both genders was social self‐esteem (p < 0.01) and for teacher‐rated social status general self‐esteem (p < 0.01). The strongest temperamental predictors of social status were lower inhibition in girls (p < 0.01, self‐ and teacher‐rated) and higher impulsivity (p < 0.01, self‐rated) and activity (p < 0.01, teacher‐rated) in boys. The present findings are consistent with the view that social functioning and peer relations are associated with individual differences in self‐concept and temperament dimensions.     

Adolescent outcomes of childhood conduct disorder among clinic-referred boys: predictors of improvement

Much remains to be learned about the adolescent outcomes of clinic-referred boys whose childhood conduct problems are serious enough to meet diagnostic criteria for conduct disorder (CD). Six structured diagnostic assessments were conducted over 7 years of 73 clinic-referred 7–12-year-old boys who met criteria for CD in Wave 1. There were substantial individual differences in the adolescent outcomes of CD, ranging from worsening to sustained recovery, with most boys showing persistent, but fluctuating levels of CD. Improvement in CD was not accounted for by treatment or incarceration, but more positive outcomes over Waves 2–7 were predicted prospectively with substantial accuracy, using a combination of baseline predictors: less initial severity of CD, fewer symptoms of attention-deficit hyperactivity disorder, higher child verbal intelligence, greater family socioeconomic advantage, and not having antisocial biological parents.     

Taking parent personality and child temperament into account in child language development

Individual differences have become increasingly important in the study of child development and language. However, despite the important role parents play in children’s language, no work has examined how parent personality impacts language development. The current study examines the impact of parent personality as well as child temperament on language development in 460 16- to 30-month-old children and 328 31- to 42-month-old children. Findings from both groups suggest multiple aspects of children’s language abilities are correlated with their parent’s personality. Specifically, parent consciousness, openness, and agreeableness positively correlate with child vocabulary size and other language abilities. Results also replicate and expand research on child temperament and language – child effortful control and surgency were positively correlated, and negative affect negatively correlated with most language abilities even after controlling for parent personality. Critically, parent and child traits appear to impact a child’s language abilities above and beyond well-known predictors of language, such as age.     

Mother's personality and infant temperament

We examined if perfectionism and the perception of being an anxious person were associated with more negative infant temperament ratings by the mothers. 386 women (mean age = 30.08; standard deviation = 4.21) in their last trimester of pregnancy completed the Multidimensional Perfectionism Scale (MPS), the Beck Depression Inventory-II (BDI-II) and an item about their perception of being or not an anxious person. The Portuguese version of the Diagnostic Interview for Genetic Studies and the Operational Criteria Checklist for Psychotic Illness were used to generate diagnoses according to DSM-IV and ICD-10 criteria. After delivery, women completed eight items of the Difficult Infant Temperament Questionnaire (developed by our team) and filled in, again, the BDI-II and were interviewed with the DIGS. Women with depression (DSM-IV/ICD-10) and probable cases of depression using different cut-offs adjusted to Portuguese prevalence (BDI-II), in pregnancy and postpartum, were excluded. The Difficult Infant Temperament Questionnaire showed to have factorial validity and internal consistency. There was a statistically significant negative correlation between perfectionism total scale score and item 6 from the temperament scale (“is your baby irritable or fussy?”). Considering MPS 3-factor solution found for pregnancy there was also a statistically significant negative correlation between SOP and the same item. Women with low SOP differed from those with medium and high SOP in the total temperament score. Moreover, the low SOP group differed from the medium group on items three and four scores. There were no significant associations with SPP, which is the dimension more closely associated with negative outcomes. There was an association between anxiety trait status (having it or not) and scoring low, medium or high in the infant temperament scale. The proportion of anxious vs. non-anxious women presenting a high score on the infant temperament scale was higher (24.2% vs. 12.9%). Linear regressions showed that SOP (low vs. medium/high) offered a significant contribution to the prediction of total temperament scale score and items 3 and 4 scores, but a logistic regression did not confirm trait anxiety as a significant predictor of mother's infant temperament perception. Concluding, a major result concerns the fact that higher levels of adaptive perfectionism (i.e. SOP) are associated (and predict) a less negative view of their infant's temperament. These results on the effect of mother's anxiety and perfectionism on the child temperament perception might have treatment implications. As perfectionism is not always maladaptive, some of its positive features could be used to enhance women's self-efficacy/sense of parental competence in their role as mothers and positive affect towards their infants. Also, antenatal interventions aimed at minimising anxiety could help to optimise infant temperament outcomes, which could, eventually, also, lead to subsequent maternal and infant mental health better outcomes.     

Bidirectional pathways between relational aggression and temperament from late childhood to adolescence

Relational aggression is linked to numerous adverse consequences. However, we know little about how temperament leads individuals to become perpetrators/victims of relational aggression, or how being a perpetrator/victim influences the development of temperament. We used longitudinal data from 674 Mexican-origin youth to examine relations between relational aggression and mother- and child-reported temperament from 5th grade (M_age = 10.8; SD = 0.60) through 11th grade (M_age = 16.8; SD = 0.50). Results show that: (a) high Negative Emotionality and low Effortful Control predicted increases in victimization; (b) low Effortful Control predicted increases in perpetration; (c) victims increased in Negative Emotionality and decreased in Effortful Control; and (d) perpetrators increased in Negative Emotionality and Surgency. Thus, temperament serves as both an antecedent to and a consequence of relational aggression.     

社会经济地位与抑郁的关系：系统综述和元分析

社会经济地位与抑郁的关系在既有研究中存在分歧,为明确两者间的整体关联强度及其影响因素,对纳入的56项研究(65个效应值)进行了元分析。结果发现：社会经济地位与抑郁存在显著的负相关(r=-0.15,95%CI [-0.18,-0.12]),但相关程度较低。此外,社会经济地位与抑郁的关系受社会经济地位测量工具、测量类型和测量形式,抑郁测量工具以及取样年代调节,但不受性别、年龄、设计类型以及个体主义文化指数的调节。该结果提示社会经济地位劣势可能是导致民众抑郁的重要风险因素。在贫富差距日益扩大的时代,关心社会底层群众生存和发展困境并建立长久而有效的帮扶机制可从社会面减少抑郁的发病率。

Subjective socioeconomic status and departmental identity interact to reduce depressive tendencies and negative affective responding for female undergraduates

How do subjective socioeconomic status (SES) and departmental identity promote the mental health of female undergraduates? We conducted a questionnaire study (Study 1) and an experimental study (Study 2) with undergraduates enrolled in a women's junior college to examine whether subjective SES and group identity have an interactive effect on mental health. Results indicated that in participants with high subjective SES, increased identification with their reference in‐group (the academic department) was associated with a decreased tendency for depression (Study 1). These individuals also showed reduced negative affect when responding in situations of social exclusion (Study 2). These effects were absent, or had a reduced intensity in participants with low subjective SES. In sum, subjective SES and departmental identity interact to reduce depressive tendencies and negative affective responding for female undergraduates. Individuals with higher subjective SES may gain more benefits from group identity. We have discussed the implications of these findings.     

The role of psychosocial processes in explaining the gradient between socioeconomic status and health

The gradient between socioeconomic status (SES) and health is well established: Many measures of health show that health increases as SES increases. However, the mechanisms underlying this association are not well understood. Behavioral, cognitive, and affective tendencies that develop in response to the greater psychosocial stress encountered in low-SES environments may partially mediate the impact of SES on health. Although these tendencies might be helpful for coping in the short term, over time they may contribute to the development of allostatic load, which increases vulnerability to disease. Debate remains regarding the direction of causation between SES and health, the impact of income inequality, the interaction of SES with race-ethnicity and gender, and the effects of SES over the life course.     

The association between low socioeconomic status and depressive symptoms depends on temperament and personality traits

Socioeconomic status and personality traits are known to be associated with depression risk. We examined whether temperament and personality traits modified the association between socioeconomic status and depressive symptoms. The participants were 2678 individuals from the Cardiovascular Risk in Young Finns study, aged 18-49 during the three study waves in 1997, 2001, and 2007 included in the present study. Temperament was assessed with the Temperament and Character Inventory, personality with the Five Factor Model, and depressive symptoms with a modified version of Beck’s Depression Inventory. Education, occupational status, and income level were used as indicators of socioeconomic status. Results of multilevel linear regression analysis indicated that low occupational status and income were associated with high depressive symptoms particularly in individuals with high neuroticism or harm avoidance, and with low extraversion or reward dependence. High persistence also strengthened the negative association between income and depressive symptoms, but this interaction effect was not observed with conscientiousness. The mental health risks of low socioeconomic status may therefore be most potent among individuals who are sensitive to negative and threatening stimuli.     

Attachment and temperament in early childhood; implications for later behavior problems

In the context of a French validation study, the Child Behavior Checklist (CBCL) was administered to more than 3000 French speaking mothers of 5‐year‐old children. Scores were factor‐analyzed. Principal components analysis revealed four dimensions: externalizing and internalizing behavior problems, immaturity and somatoform disorders. Another sample of 40 mothers participated in a longitudinal study, filling in the CBCL when their children were 5 years old. These children had been observed previously in the Strange Situation (SSP) at 21 months. Several dichotomous variables derived from the SSP (e.g. secure versus insecure, proximal versus distal interaction with the mother, avoidant behavior) have been used as predictors of the four dimensions extracted from the CBCL. Hierarchical regressions showed that proximal behaviors with the mother, which reflect temperamental characteristics independently of the quality of attachment, predicted internalizing problems, whereas avoidance of the mother, or insecure–avoidant attachment, predicted internalizing as well as externalizing problems at 5 years of age. These results show that attachment and temperament, as assessed by the SSP, may each have specific implications for later behavior problems. Copyright © 2000 John Wiley & Sons, Ltd.     

Romantic relationship distress,gender, socioeconomic status,and inflammation: A preregistered report

Poor quality romantic relationships increase risk for health problems; elevated systemic inflammation is one promising underlying mechanism. This registered report utilized data from three publicly available data sets with large sample sizes (Add Health, MIDUS, NSHAP) to test this possibility. An internal meta‐analysis across all three studies determined that romantic relationship distress was unrelated to inflammation (assessed via C‐reactive protein levels). In addition, this link was not moderated by gender, socioeconomic status (SES), or the combination of gender and SES.
