Preadolescents with immigrant backgrounds: the relationship between emotional problems, parental achievement values, and comparison

Although strong parental achievement values have been associated with positive outcomes among children (e.g., academic success), they have also been connected to emotional problems. The latter effect may be the result of pressure related to such things as parental comparison of filial achievement, which appears to be more predominant among immigrant parents as compared with non-immigrant parents.Our goals were to assess the following: 1) whether higher levels of parental achievement values and comparison are found among immigrant preadolescents; and (2) whether comparison (i.e., comparing a child's achievements with those of siblings and peers) can account for the link between strong parental achievement values and emotional problems among the children of immigrants.The sample included 902 preadolescents between the ages of 10 and 12 years from two Norwegian cities: Oslo (79%) and Bergen (21%). Forty-seven percent of the sample had immigrant parents, and the others had non-immigrant parents. A self-administered questionnaire was completed by fifth, sixth, and seventh graders from fourteen schools during normal school hours; the questionnaires were completed after school by students from Turkey and Sri Lanka. The questionnaire included measures of emotional problems, parental achievement values, comparison, and school hassles. We used a moderated mediation model to test whether the relationship between parental achievement values and emotional problems was accounted for by comparison and to look at whether this mediation was stronger for preadolescents with immigrant backgrounds as compared with their non-immigrant peers. Background and academic factors that could confound the unique relationships among the main variables were adjusted for in the analyses.The association between parental achievement values and emotional problems was found to be mediated by comparison. Higher levels of parental achievement values were associated with more comparison, and this relationship was stronger for preadolescents with immigrant backgrounds. Comparison was only linked to emotional problems in preadolescents with immigrant backgrounds.This study suggests that stronger parental achievement values among immigrants as compared with non-immigrants in Norway are found as early as preadolescence and that comparison may be part of the link between strong parental achievement values and emotional problems

The Multidimensional Self-Control Scale (MSCS): Development and validation

Trait self-control is important for well-being and mental and physical health. Most extant measures of self-control are limited in that they do not account for the multidimensionality and specificity of the trait. The aim of this study was to develop and validate a multidimensional and hierarchical scale of self-control in a full and a short version. The development of the Multidimensional Self-Control Scale (MSCS) and the Brief Multidimensional Self-Control Scale (BMSCS) was based on focus groups, a pilot, a main, and a validation sample (total N = 2,409). The 29-item MSCS consists of 6 first-order factors (Procrastination, Attentional Control, Impulse Control, Emotional Control, Goal Orientation, and Self-Control Strategies), 2 second-order factors (Inhibition and Initiation), and a third-order self-control factor. The 8 items in BMSCS provides a general trait self-control score. Findings from exploratory and confirmatory factor analyses supported the structures across samples, and internal consistency was acceptable. Assessment for acquiescence and sex differences indicated no major impacts on the scales. Strong convergent validity was observed with the Self-Control Scale (SCS) and the Brief Self-Control Scale (BSCS), as well as to other similar concepts. The MSCS subscales discriminated well between each other. Assessment of incremental validity of the MSCS over SCS, when controlling for sex and personality, showed significant increases in explained variance when predicting habits, hardiness, and life satisfaction. Similar significant results were observed for the BMSCS over the BSCS. Overall, results indicate that the new scales are useful measures that integrate recent theoretical and empirical findings of trait self-control.

Justice sensitivity is undergirded by separate heritable motivations to be morally principled and opportunistic

Injustice typically involves some people benefitting at the expense of others. An opportunist might then be selectively motivated to amend only the injustice that is harmful to them, while someone more principled would respond consistently regardless of whether they stand to gain or lose. Here, we disentangle such principled and opportunistic motives towards injustice. With a sample of 312 monozygotic- and 298 dizygotic twin pairs (N = 1220), we measured people’s propensity to perceive injustice as victims, observers, beneficiaries, and perpetrators of injustice, using the Justice Sensitivity scale. With a biometric approach to factor analysis, that provides increased stringency in inferring latent psychological traits, we find evidence for two substantially heritable factors explaining correlations between Justice Sensitivity facets. We interpret these factors as principled justice sensitivity (h2 = 0.45) leading to increased sensitivity to injustices of all categories, and opportunistic justice sensitivity (h2 = 0.69) associated with increased sensitivity to being a victim and a decreased propensity to see oneself as a perpetrator. These novel latent constructs share genetic substrate with psychological characteristics that sustain broad coordination strategies that capture the dynamic tension between honest cooperation versus dominance and defection, namely altruism, interpersonal trust, agreeableness, Social Dominance Orientation and opposition to immigration and foreign aid

On the importance of parenting in externalizing disorders: an evaluation of indirect genetic effects in families

Background: Theoretical models of the development of childhood externalizing disorders emphasize the role of parents. Empirical studies have not been able to identify specific aspects of parental behaviors explaining a considerable proportion of the observed individual differences in externalizing problems. The problem is complicated by the contribution of genetic factors to externalizing problems, as parents provide both genes and environments to their children. We studied the joint contributions of direct genetic effects of children and the indirect genetic effects of parents through the environment on externalizing problems. Methods: The study used genome-wide single nucleotide polymorphism data from 9,675 parent–offspring trios participating in the Norwegian Mother Father and child cohort study. Based on genomic relatedness matrices, we estimated the contribution of direct genetic effects and indirect maternal and paternal genetic effects on ADHD, conduct and disruptive behaviors at 8 years of age. Results: Models including indirect parental genetic effects were preferred for the ADHD symptoms of inattention and hyperactivity, and conduct problems, but not oppositional defiant behaviors. Direct genetic effects accounted for 11% to 24% of the variance, whereas indirect parental genetic effects accounted for 0% to 16% in ADHD symptoms and conduct problems. The correlation between direct and indirect genetic effects, or gene–environment correlations, decreased the variance with 16% and 13% for conduct and inattention problems, and increased the variance with 6% for hyperactivity problems. Conclusions: This study provides empirical support to the notion that parents have a significant role in the development of childhood externalizing behaviors. The parental contribution to decrease in variation of inattention and conduct problems by gene–environment correlations would limit the number of children reaching clinical ranges in symptoms. Not accounting for indirect parental genetic effects can lead to both positive and negative bias when identifying genetic variants for childhood externalizing behaviors.publishedVersio

Socioeconomic status and sick leave granted for mental and somatic disorders: a prospective study of young adult twins

Background Low socioeconomic status (SES), indicated by low income and education, has consistently been found to be a strong predictor of sick leave. Several possible pathways from SES to sick leave have been described in previous literature, but there are also evidence indicating that the association can be confounded by common underlying factors. This study utilizes a population-based sample of employed young adult twins to estimate (i) the degree to which education and income are prospectively related to sick leave granted for mental, somatic, and any disorder, and (ii) whether these associations are confounded by familial factors. Methods Registry data on educational attainment and income at age 30 and subsequent sick leave were available for 6,103 employed young adult twins, among which there were 2,024 complete twin pairs. The average follow-up time was 6.57 years. Individual-level associations and fixed effects within twin pairs were estimated. Results Low education and income were associated with sick leave granted for both mental and somatic disorders, and with sick leave granted for any disorder. Associations were attenuated within dizygotic twin pairs and reduced to non-significance within monozygotic twin pairs, suggesting influence of familial factors on the associations between SES and sick leave. Conclusions Low SES is associated with a higher level of sick leave granted for both mental and somatic disorders among young adults, but these associations are confounded by factors that are common to co-twins. Education and income are therefore not likely to strongly affect sick leave in young adulthood

Effectiveness of the International Child Development Programme: Results from a randomized controlled trial

This study aimed to evaluate the effectiveness of the International Child Development Programme (ICDP), a group-based parenting programme used internationally and implemented nationally in Norway. We used a cluster randomized controlled trial in which 81 groups were randomly assigned to either the intervention or waitlist control condition after the baseline data collection. A total of 590 parents completed at least one of three questionnaires (administrated before and after ICDP and 4 months after completing the intervention). Primary outcomes included parental self-efficacy, parental emotion sensitivity and positive involvement with their child. Secondary outcomes included parents' perceptions of their relationship with the child, child-rearing conflicts and the child's psychosocial health. We found significant effects favouring the intervention arm following the intervention and at follow-up on two primary outcomes (parental self-efficacy and emotion sensitivity). For the secondary outcomes, we found a significant reduction in child-rearing conflict at the 4-month follow-up, increased closeness to the child, reduced child internalizing difficulties and increased prosocial behaviour immediately following the intervention. However, ICDP seems to have limited effects on parent-reported changes in children. We conclude that ICDP as a universal preventive programme offered to parents in groups can be effective in strengthening parental self-efficacy and improving parental emotion sensitivity.publishedVersio
