Association between maladaptive parenting and child self-control over time: cross-lagged study using a monozygotic twin difference design

Effectiveness of Learning through Play Plus (LTP Plus) Parenting Intervention on Behaviours of Young Children of Depressed Mothers: A Randomised Controlled Trial

Evidence has shown that parenting intervention programmes improve parental knowledge, attitudes, and practices, which helps in promoting child development. This study aims to examine the effectiveness of parenting intervention in improving child behaviours. This is a secondary analysis of data from a cluster-randomised controlled trial with depressed mothers aged 18-44 years with a child aged 0 to 36 months. This paper reports findings from the dataset of participants with a child aged between 24 and 36 months. Villages (n = 120) were randomised into either of two arms: learning through play plus (LTP Plus) or treatment as usual (TAU). LTP Plus is a 10-session, group parenting intervention integrated with cognitive behaviour therapy, delivered over 3 months. This secondary analysis reports findings on the Eyberg Child Behaviour Inventory (ECBI) and the Home Observation for Measurement of the Environment (HOME). Findings show a significant improvement in child behaviour (ECBI) scores (p < 0.011) and HOME scores (p < 0.001) in the intervention group compared to TAU at 3-month follow-up. In a low-resource setting, low-cost group parenting intervention delivered by community health workers has the potential to improve child behaviours and quality of the home environment. Parenting interventions aimed at improving child behavioural problems can have significant implications for the child, family, and broader societal outcomes. Addressing behavioural problems in early years, parenting interventions can potentially reduce long-term consequences and costs associated with untreated child behavioural issues.

Comparing findings from the random-intercept cross-lagged panel model and the monozygotic twin difference cross-lagged panel model: Maladaptive parenting and offspring emotional and behavioural problems

Background

In this study we compare results obtained when applying the monozygotic twin difference cross-lagged panel model (MZD-CLPM) and a random intercept cross-lagged panel model (RI-CLPM) to the same data. Each of these models is designed to strengthen researchers' ability to draw causal inference from cross-lagged associations. We explore differences and similarities in how each model does this, and in the results each model produces. Specifically, we examine associations between maladaptive parenting and child emotional and behavioural problems in identical twins aged 9, 12 and 16.

Method

Child reports of 5698 identical twins from the Twins Early Development Study (TEDS) were analysed. We ran a regular CLPM to anchor our findings within the current literature, then applied the MZD-CLPM and the RI-CLPM.

Results

The RI-CLPM and MZD-CLPM each enable researchers to evaluate the direction of effects between correlated variables, after accounting for unmeasured sources of potential confounding. Our interpretation of these models therefore focusses primarily on the magnitude and significance of cross-lagged associations. In both the MZD-CLPM and the RI-CLPM behavioural problems at age 9 resulted in higher levels of maladaptive parenting at age 12. Other effects were not consistently significant across the two models, although the majority of estimates pointed in the same direction.

Conclusion

In light of the triangulated methods, differences in the results obtained using the MZD-CLPM and the RI-CLPM underline the importance of careful consideration of what sources of unmeasured confounding different models control for and that nuance is required when interpreting findings using such models. We provide an overview of what the CLPM, RI-CLPM and MZD-CLPM can and cannot control for in this respect and the conclusions that can be drawn from each model.

Assortative parenting and assortative cross-parenting: New views of parental preference for selected children

Two novel parenting terms are introduced into the literature on parent-child relationships. The first term, assortative parenting, references a familiar, but poorly defined concept regarding parental affinity for a given child. The second term, assortative cross-parenting, denotes a previously unrecognized relationship phenomenon, namely parental attraction to a child who displays favored qualities expressed by the parent's partner. These terms derived from interviews with same-sex couples, but easily apply to heterosexual couples, as well. The proposed concepts and labels should initiate new lines of inquiry that can illuminate unstudied aspects of family dynamics. Given that improved reproductive techniques and revised societal attitudes are continually creating novel family structures, studies of personal relationships and the families in question would benefit by admitting these concepts into ongoing research programs.

Annual Research Review: Stability of psychopathology: lessons learned from longitudinal population surveys

BACKGROUND

Psychopathology has been long recognized as a fluctuating process with various expressions over time, which can only be properly understood if we follow individuals and their social context from childhood up until adulthood. Longitudinal population-based studies have yielded powerful data to analyze this process. However, the resulting publications have not been reflected upon with regard to (a) the homotypic and heterotypic stability of internalizing and externalizing problems and (b) how transactions between psychopathology and environmental factors shape its development.

METHODS

In this narrative review, we primarily focused on population-based studies that followed cohorts repeatedly from an early age (<18 years) onwards, across multiple stages of development, using statistical methods that permit inferences about within-person bidirectional associations between internalizing and externalizing problems or psychopathology-environment transactions.

RESULTS

There is robust evidence that mental health problems in childhood or adolescence predict psychiatric problems later in development. In terms of the broadband domains internalizing and externalizing problems, homotypic stability greatly exceeds heterotypic stability and transitions from purely internalizing to purely externalizing problems or vice versa are rare. Homotypic rank-order stabilities seem to increase over time. Findings regarding transactions with environmental factors are less robust, due to widely varying research topics and designs, and a scarcity of studies that separated between-person differences from within-person changes. In general, however, the literature shows little consistent evidence for substantial mutual prospective influences between psychopathology and environmental factors.

CONCLUSIONS

Longitudinal surveys have strongly augmented insight into homotypic and heterotypic stability and change. Attempts to unravel the myriad of risk and protective factors that place individuals on particular pathways or deflect them from these pathways are still in a pioneering phase and have not yet generated robust findings. As a way forward, we propose to join forces and develop a common risk factor taxonomy.

Parenting and mobile phone addiction tendency of Chinese adolescents: The roles of self-control and future time perspective

Previous studies examined the impact of parenting on adolescents' mobile phone addiction tendencies. However, relatively few studies examined the potential mechanism underlying such a relationship. Thus, the present study further explored the mediation effect of self-control and the moderating effect of future time perspective between parenting and mobile phone addiction tendencies of Chinese adolescents. A sample of 1,349 Chinese adolescents (M_age = 15. 22 years, SD = 0.79) responded to the anonymous questionnaires regarding parenting, including parental control and parental care, self-control, future time perspective, and mobile phone addiction tendency. The results showed that (1) parental control was positively related to adolescents' mobile phone addiction tendencies, while parental care was negatively related to adolescents' mobile phone addiction tendencies; (2) self-control could mediate the pathway from both parental control and parental care to adolescents' mobile phone addiction tendencies; and (3) the indirect pathway could be moderated by future time perspective. Specifically, a high future time perspective combined with high self-control predicted a low level of mobile phone addiction tendency. In contrast, low self-control was associated with a high tendency toward mobile phone addiction, regardless of their future time perspective. The present study revealed a complex interplay between family and individual factors contributing to adolescents' mobile phone addiction tendencies.

The association between adverse childhood experiences and common mental disorders and suicidality: an umbrella review of systematic reviews and meta-analyses

Adverse childhood experiences (ACEs) are related to increased risk of common mental disorders. This umbrella review of systematic reviews and meta-analyses aimed to identify the key ACEs that are consistently associated with increased risk of mental disorders and suicidality. We searched PsycINFO, PubMed, and Google Scholar for systematic reviews and meta-analyses on the association between ACEs and common mental disorders or suicidality published from January 1, 2009 until July 11, 2019. The methodological quality of included reviews was evaluated using the AMSTAR2 checklist. The effect sizes reported in each meta-analysis were combined using a random-effects model. Meta-regressions were conducted to investigate whether associations vary by gender or age of exposure to ACEs. This review is registered with PROSPERO (CRD42019146431). We included 68 reviews with moderate (55%), low (28%) or critically low (17%) methodological quality. The median number of included studies in these reviews was 14 (2-277). Across identified reviews, 24 ACEs were associated with increased risk of common mental disorders or suicidality. ACEs were associated with a two-fold higher odds of anxiety disorders (pooled odds ratios (ORs): 1.94; 95% CI 1.82, 2.22), internalizing disorders (OR 1.76; 1.59, 1.87), depression (OR 2.01; 1.86, 2.32) and suicidality (OR 2.33; 2.11, 2.56). These associations did not significantly (P > 0.05) vary by gender or the age of exposure. ACEs are consistently associated with increased risk of common mental disorders and suicidality. Well-designed cohort studies to track the impact of ACEs, and trials of interventions to prevent them or reduce their impact should be global research priorities.

Self-control, Mental Health Problems, and Family Functioning in Adolescence and Young Adulthood: Between-person Differences and Within-person Effects

Adolescents' self-control develops in the context of mental health and family functioning, but it is unclear how the interplay of self-control, mental health, and family functioning unfolds across time within individuals. Separating within-person from between-person effects, random-intercept cross-lagged panel models were applied to adolescents (from ages 11 to 26) from a Dutch cohort (n = 2228, 51% female). Adolescents with low self-control were likely to have mental health problems and poorly functioning families. Although within-person changes in the study variables were not meaningfully associated in a reciprocal manner, changes in self-control and mental health were concurrently associated. This suggests that besides stable connections between self-control, mental health, and family functioning in adolescence and young adulthood, changes in self-control and mental health are developmentally linked as well.

Technology-Assisted Parenting Interventions for Families Experiencing Social Disadvantage: a Meta-Analysis

Technology-assisted interventions have been identified as a means to increase accessibility and enhance engagement of parenting programs. The current meta-analytic review examines the effectiveness of these interventions in families experiencing social disadvantage. A literature search was conducted spanning March 2007-June 2019. Nine studies met inclusion criteria (total of 864 participants) which included an evaluation of a parenting intervention for families with at least one of the following demographic challenges, low socioeconomic status, single parenthood, and/or young parenthood. Interventions (or a component of the intervention) were delivered by computer, cell phone, smartphone, and/or tablet. Data were organized into three categories: parental psychological well-being (e.g., self-esteem, social support), parenting (e.g., observed or self-reported parenting behavior), and child behavior (e.g., disruptive behavior). Effect sizes (Hedges' g) were calculated and moderators (i.e., contact with an interventionist, intervention length, publication year, % female parents, mean parent age, parental education, % minority, and child age) were examined through Q-statistics and meta-regression, as appropriate. Intervention showed a near-significant impact on parental psychological well-being (g = .35, p = .051). Furthermore, interventions that did not include direct contact with an interventionist showed no evidence of effectiveness (g = - .02); interventions that incorporated contact were significantly more effective (g = .68). In addition, intervention length moderated intervention effectiveness; shorter interventions yielded greater improvements in well-being, compared with longer interventions. Interventions were also associated with significant improvements in parenting (g = .38) and child behavior (g = .39). These findings provide support for the use of technology-assisted parenting interventions in populations experiencing social disadvantage.

Twins and Causal Inference: Leveraging Nature's Experiment

In this review, we discuss how samples comprising monozygotic and dizygotic twin pairs can be used for the purpose of strengthening causal inference by controlling for shared influences on exposure and outcome. We begin by briefly introducing how twin data can be used to inform the biometric decomposition of population variance into genetic, shared environmental, and nonshared environmental influences. We then discuss how extensions to this model can be used to explore whether associations between exposure and outcome survive correction for shared etiology (common causes). We review several analytical approaches that can be applied to twin data for this purpose. These include multivariate structural equation models, cotwin control methods, direction of causation models (cross-sectional and longitudinal), and extended family designs used to assess intergenerational associations. We conclude by highlighting some of the limitations and considerations that researchers should be aware of when using twin data for the purposes of interrogating causal hypotheses.

Parenting practices in childhood and depression, anxiety, and internalizing symptoms in adolescence: a systematic review

PURPOSE

Parenting practices represent important and modifiable factors for health and wellbeing in children and adolescents; however, strength and quality of studies examining relationships between parenting practices in childhood and risk of depression and anxiety in adolescence are unclear. The objective of this systematic review was to synthesize the longitudinal literature that describes these associations.

METHODS

Six electronic databases were searched for articles published through March 2018. Eligible articles were published in the English language, peer-reviewed, and had prospective cohort study designs. Articles eligible for inclusion examined positive and negative parenting practices of parents and/or guardians when study subjects were between 0 and 9 years of age, and symptoms of depression, anxiety, and internalizing symptoms when subjects were between 10 and 19 years of age. Heterogeneity of included articles precluded meta-analysis: findings were reported narratively.

RESULTS

4558 references were screened for inclusion, and 19 articles met eligibility criteria and were included for review. Ten articles examined positive parenting practices, and four demonstrated statistically significant associations between positive parenting practices and lower risk of adolescent depression, anxiety, and/or internalizing symptoms. Fifteen articles examined negative parenting practices, and five demonstrated significant associations between negative parenting practices and higher risk of adolescent depression, anxiety, and/or internalizing symptoms.

CONCLUSION

This review demonstrates that the evidence base supporting longitudinal associations between parenting practices in childhood and adolescent symptoms of depression, anxiety, and internalizing problems is inconsistent. Findings from this review highlight limitations of the existing literature and identify understudied parenting dimensions that require further investigation.

Don't touch: Developmental trajectories of toddlers' behavioral regulation related to older siblings' behaviors and parental discipline

Behavioral regulation is one of the key developmental skills children acquire during early childhood. Previous research has focused primarily on the role of parents as socializing agents in this process, yet it is likely that older siblings also are influential given the numerous daily interactions between siblings. This exploratory longitudinal study investigated developmental heterogeneity in behavioral regulation during toddlerhood and the early preschool years (18 to 36 months) and relations with older siblings' control and behavioral regulation while taking into account parental discipline. Toddlers were visited at home at 18, 24, and 36 months and observed during a gift-delay task with their older sibling in 93 families. Behavioral regulation of both siblings and gentle and harsh control of the older sibling were coded during the sibling gift-delay task, which was validated using parent-reports of toddlers' internalized conduct. Analyses revealed five distinct developmental trajectories among toddlers' behavioral regulation, revealing different patterns of developmental multifinality and equifinality. Older siblings' harsh control and parental discipline differed across toddler trajectory groups. Older siblings' behaviors covaried with the toddlers' behavioral regulation suggesting that older siblings may be acting as models for younger siblings, as well as disciplining and teaching toddlers to resist temptation.

Self-control in early childhood: Individual differences in sensitivity to early parenting

OBJECTIVE

This study extends existing research on the role of infant temperament as a moderator of the association between the quality of parent-child relationships and children's self-control during the pre-school years. In particular, we focus on the potential moderating role of a dimension of early infant temperament known as behavioral inhibition. Assumptions formulated within the diathesis-stress, the vantage-sensitivity, and the differential susceptibility models of individual differences in environmental sensitivity are tested.

METHOD

Data are from the Millennium Cohort Study, a nationally representative birth cohort of 18,552 infants born in the United Kingdom during 2000/01.

RESULTS

The results show that the quality of both mother-child and father-child relationships are associated with children's development of self-control in early childhood. Additionally, individual differences in infant temperament moderate the association between mother-child conflict and children's development of self-control. Specifically, high behavioral inhibition shows a vantage-sensitivity pattern for mother-child conflict.

CONCLUSIONS

Aspects of both mothers' and fathers' relationships with their young children independently predict variations in self-control. This study also provides an initial indication that behavioral inhibition, a temperamental trait best-known for being a risk factor for anxiety, may provide small benefits in relation to young children's self-control development.

Parental socioeconomic status, adolescents' screen time and sports participation through externalizing and internalizing characteristics

The socioeconomic status of parents is reportedly closely related to the digital screen usage and physical inactivity levels of children and adolescents. Internalizing and externalizing behavior characteristics may be linked to these associations and explain them. The purpose of the present study was to investigate the effects of parents' socioeconomic status (SES) on youths' total screen time along with physical inactivity through internalizing and externalizing behavior characteristics. Thus, we examined associations between parents' socioeconomic status (using scores based on several indicators) and adolescents' total digital screen exposure and physical inactivity level, together with the potentially predicting role of the adolescents' internalizing and externalizing behavior. For this, we assessed the internalizing and externalizing problem characteristics, total screen time exposure, physical inactivity level and parental socioeconomic status of a large cohort sample of Finnish adolescents (the Northern Birth Cohort, 1986 comprised 2899 males and 3059 females). The present study includes data collected in two phases, in 1985–1986 and 2000–2001. Path modeling suggests that a low SES of parents was directly associated with adolescents' physical inactivity level, while externalizing characteristics were a significant and additional contributing factor in adolescents' level of screen exposure in both genders. Gender moderated the relationship between adolescents' internalizing and externalizing characteristics and physical inactivity levels. The results also suggest that parents’ socioeconomic status constitutes a risk factor in relation to media screen exposure only in female adolescents. Implications of the findings are discussed.

Investigating the association between family connectedness and self-control in adolescence in a genetically sensitive design

Family connectedness is key for the development of self-control in early and middle childhood. But is family connectedness still important during the transitional phase of adolescence, when adolescents demand more independence from their parents and rely more on their peers? The aim of the present study was to investigate the association between family connectedness and self-control, and whether it still holds in adolescence using a genetically sensitive design. Data were used from a large sample of twins aged 14 (N = 11,260) and aged 16 (N = 8175), all enrolled in the Netherlands Twin Register. We applied bivariate twin models and monozygotic twin difference models to investigate the association between family connectedness and self-control and to unravel to what extent genetic and environmental factors explain this association. The results showed that more family connectedness is significantly related to better self-control in adolescence, albeit with a small effect size. Twin analyses revealed that this association was mainly explained by common genetic factors and that the effects of environmental factors were small. The current findings confirm the role of family connectedness in adolescent self-control. Importantly, however, the results demonstrate that phenomena we see within families seem the product of parent and children sharing the same genes rather than being exclusively attributable to environmental processes.

Effectiveness of the Stepping Stones Triple P group parenting program in reducing comorbid behavioral problems in children with autism

Children with autism spectrum disorders often exhibit comorbid behavioral problems. These problems have an impact on the severity of the core symptoms, the progression of the disorder as well as on the families’ quality of life. We evaluated the effectiveness of the Stepping Stones Triple P group parent training program as a supplementary intervention in the treatment of children with autism spectrum disorder. Therefore, we employed a single group repeated measures design and assessed child variables via parents’ and teachers’ judgments at four successive time points. The participants were parents of 24 children with autism spectrum disorder aged between 3.6 and 12 years. We found a significant reduction of comorbid behavioral problems in the children, primarily in the parents’ judgment at follow-up. Furthermore, a reduction of the autism spectrum disorder core symptoms emerged. The teachers’ judgment particularly revealed an improvement in children’s social relationships. Effect sizes were large ( ƞ2 ranging from 0.14 to 0.23). The findings demonstrate the effectiveness of the Stepping Stones Triple P as a supplementary intervention for reducing comorbid behavioral problems in the treatment of children with autism spectrum disorder. Higher parental self-efficacy and parental attributions, including parents’ ability to influence child problem behaviors, are discussed as important factors for the effectiveness of Stepping Stones Triple P.

The Role of Compassionate and Self-Image Goals in Predicting Psychological Controlling and Facilitative Parenting Styles

People enter into parental roles with a range of different motivations for parenting. To date, however, there is limited research assessing maternal motivations, concerns, and anxieties in their parenting styles. While some mothers are confident and child focused, others have concerns with performing parenting behaviors, and can be self-focused, shame prone, and self-judgmental. Two studies explored these two dimensions in relation to degree of controlling and facilitative parenting styles in the mothers of 3-9-year-old children. In study one, 151 mothers took part in an online survey measuring these two dimensions using the compassionate goals and self-image goals scales (Crocker and Canevello, 2008), in relation to facilitative and controlling parenting styles. As predicted, after controlling for child behavior, parental mental health, and parental self-efficacy, self-focused and shame avoidant concerns were associated with greater psychologically controlling parenting. In contrast a compassionate focused orientation was associated with greater facilitative parenting. In study two, 198 mothers were randomly assigned to either compassion focused goals, self-image goals, or control condition, which was manipulated by varying the instructions provided to participants. Emotional responses (e.g., angry, sad, and shame) to difficult parenting scenarios did not differ depending on whether participants were prompted with compassionate goal, self-image goal, or control condition instructions. The findings from study 1 demonstrate how goal motivation can influence parenting style, with the results from study 2 suggesting that instruction alone is insufficient to shift goal orientation.

Longitudinal association of inflammation with depressive symptoms: A 7-year cross-lagged twin difference study

BACKGROUND

The direction of the association between inflammation and depressive symptoms remains inconsistent. The objective of this study was to evaluate the temporal relationship between inflammation and depressive symptoms, and to assess the role of genetic factors on this association.

METHODS

In this longitudinal cross-lagged twin difference study, we examined 166 (83 pairs) middle-aged male twins recruited from the Vietnam Era Twin Registry, who were assessed at baseline and after 7 years of follow-up. We assayed plasma levels of two inflammatory biomarkers, interleukin-6 (IL-6) and high sensitivity C-reactive protein (CRP) and measured depressive symptoms using the Beck Depression Inventory-II (BDI). To evaluate the direction of the association, we constructed multivariable mixed-effects regression models and calculated standardized beta-coefficients to compare the strength of the within-pair association for both pathways. We then conducted a stratified analysis by zygosity and assessed the associations in monozygotic and dizygotic twin pairs separately.

RESULTS

The 166 twins were 95% white and had a mean (SD) age of 54 (3) years at baseline. The cross-lagged analysis showed significant and positive associations from visit 1 IL-6 to visit 2 BDI across all models (beta-coefficients ranging from 0.18 to 0.22). However, the opposite pathway (visit 1 BDI to visit 2 IL-6) was not significant after adjusting for confounding factors. In contrast, visit 1 BDI was significantly associated with visit 2 CRP in all models (beta-coefficients ranging from 0.23 to 0.33), while the opposite pathway (visit 1 CRP to visit 2 BDI) showed no significant association. When stratifying by zygosity, significant associations from IL-6 to depression were only seen in monozygotic twins, but associations from depression to CRP were more robust in dizygotic twins, which implies that genetic factors may play a role in this association.

CONCLUSIONS

The association between inflammation and depression may be bidirectional. Elevated IL-6 levels are more likely to be a risk factor of depression rather than a consequence, while the opposite may be true for elevated CRP. The biological underpinnings of these bidirectional pathways need further evaluation.

The Mediating Effect of Self-Control on Parenting and Delinquency: A Gendered Approach With a Multinational Sample

This study aims to clarify the relationships between parenting techniques, low self-control, and juvenile delinquency in Gottfredson and Hirschi's general theory of crime while controlling for alternative explanations of delinquency. We relied on a sample of 35,511 adolescent students from 31 countries from the International Self-Report Delinquency 2 Study. Results indicate that parenting exhibits a direct effect on adolescents' violence perpetration and property offending, and that while self-control weakens the strength of this relationship, it fails to fully mediate it. Males reported lower levels of self-control, exposure to poorer parenting techniques, and higher rates of violence perpetration and property offending. The relationship between parenting, self-control, and juvenile delinquency was similar for females and males. These results provide evidence that parenting has important implications for adolescents' involvement in delinquency above and beyond its influence on their level of self-control.

Positive Parenting Moderates the Association between Temperament and Self-Regulation in Low-Income Toddlers

Self-regulation develops rapidly during the toddler years and underlies many important developmental outcomes, including social-emotional competence and academic achievement. It is important to understand factors that contribute to early self-regulation skills among children at risk for adjustment difficulties in these domains, such as children growing up in poverty. The current study examined mother-reported child temperament (negative affect, effortful control) and observed maternal parenting (during a mother-child free play) as contributing factors to toddlers' observed self-regulation during delay of gratification tasks at 27 months (snack delay) and 33 months (gift delay). Participants were 198 toddlers (M age = 27 months; 53% boys; 48% non-Hispanic white) and their mothers from low-income families. Mothers' negative parenting characterized by negative affect, hostility, and negative control was associated with poorer self-regulation contemporaneously. Toddlers' lower negative affect and higher effortful control predicted better self-regulation at 33 months, but positive parenting characterized by positive affect and sensitivity moderated these associations at both time points. Specifically, we found a buffering effect of high positive parenting among toddlers with a temperamental risk and a deleterious effect of low positive parenting despite toddlers' temperamental strength. Results highlight the importance of positive parenting for fostering the development of self-regulation among toddlers growing up with poverty-related and child-level risks.

Brain Activity, Low Self-Control, and Delinquency: An fMRI Study of At-Risk Adolescents

PURPOSE

A vast literature finds that low self-control is associated with a myriad of antisocial behaviors. Consequently, increasing attention has focused on the causes of low self-control. While criminologists have directed significant attention to studying its social causes, fewer studies have considered its neural bases.

METHODS

We add to this nascent body of research by using data collected on an at-risk sample of adolescents participating in the ongoing Michigan Longitudinal Study. We examine the functioning of prefrontal and limbic regions of the brain during failed inhibitory control, assessed using the go/no-go task and functional magnetic resonance imaging, in relation to low self-control and self-reported delinquency.

RESULTS

Results indicate that greater activation localized in the anterior cingulate cortex (ACC) during failed inhibitory control is negatively associated with low self-control. Moreover, the association between ACC activity and later delinquency is mediated through low self-control.

CONCLUSIONS

Findings of this study demonstrate the utility of integrating neuroscientific and criminological perspectives on the causes of antisocial behavior. Concluding remarks address the theoretical and policy implications of the findings, as well as directions for future research.

Parental Self-Control and the Development of Male Aggression in Early Childhood: A Longitudinal Test of Self-Control Theory

A number of studies have evaluated associations between parenting practices, adolescent self-control, and adolescent antisocial behavior. Yet, few studies have examined associations between these constructs in early childhood or examined the extent to which both maternal and paternal self-control shapes them. To address these gaps, the current study utilizes longitudinal data collected on a sample of 117 Dutch boys and their parents to investigate the across time interrelationships between parental self-control, ineffective parenting, child self-control, and child aggression. The results provide evidence of an indirect association between maternal self-control and early childhood self-control through maternal ineffective parenting, an indirect association between maternal ineffective parenting and early childhood aggression through early childhood self-control, and an indirect association between maternal self-control and early childhood aggression through both maternal ineffective parenting and early childhood self-control. In contrast, paternal self-control and paternal ineffective parenting were unrelated to child self-control and child aggression. The implications and limitations of the study are discussed.

Genetic and Environmental Influences on Self-Control: Assessing Self-Control with the ASEBA Self-Control Scale

This study used a theoretically-derived set of items of the Achenbach System of Empirically Based Assessment to develop the Achenbach Self-Control Scale (ASCS) for 7-16 year olds. Using a large dataset of over 20,000 children, who are enrolled in the Netherlands Twin Register, we demonstrated the psychometric properties of the ASCS for parent-, self- and teacher-report by examining internal and criterion validity, and inter-rater and test-retest reliability. We found associations between the ASCS and measures of well-being, educational achievement, and substance use. Next, we applied the classical twin design to estimate the genetic and environmental contributions to self-control. Genetic influences accounted for 64-75% of the variance in self-control based on parent- and teacher-report (age 7-12), and for 47-49% of the variance in self-control based on self-report (age 12-16), with the remaining variance accounted by non-shared environmental influences. In conclusion, we developed a validated and accessible self-control scale, and show that genetic influences explain a majority of the individual differences in self-control across youth aged 7-16 years.

Etiological Influences on Perceptions of Parenting: A Longitudinal, Multi-Informant Twin Study

Children and their parents often differ in their perception of the relationship they share. As this relationship changes developmentally, the nature of these differences may also change. Longitudinal genetic designs can be used to investigate the developmental etiologies of shared and distinct perceptions. In this study, we used longitudinal psychometric models to analyze child and parent reports of negative parenting for 6417 twin pairs from the Twins Early Development Study at ages 9, 12 and 14 years. Within-time cross-reporter correlations, indicating the degree to which children and parents perceived negative parenting behaviors similarly at each age, were moderate (r = .44 - .46). Longitudinal genetic analyses revealed these shared perceptions to be relatively stable during the transition into adolescence, with this stability driven by a combination of children's genetic factors and family-wide environmental factors. In contrast, child- and parent-specific perceptions of parenting were predominantly age-specific, a developmental pattern underpinned by child genetic factors and a combination of family-wide and unique environmental influences. These results and their implications are discussed in the context of interplay between reciprocal interactions, subjective insight and developmental behavioral change in the parent-child relationship.

A longitudinal study of self-control at the transition to secondary school: Considering the role of pubertal status and parenting

Higher self-control in children and adolescents is associated with a range of positive outcomes in adulthood. However, little is known about the naturalistic development of self-control during early adolescence and the factors that affect this. We examined the role of puberty and parenting style as theoretically important influences on stability and change in self-control. A longitudinal (3 waves), multiple-informant dataset of children entering early adolescence (M = 11 years) was used to explore longitudinal change in self-control using latent growth curve modelling. Children's self-control declined during the one-year study period and declines were associated with children's behavioural and social functioning. Associations with self-control were found for pubertal status and parental warmth and hostility, but not for parental discipline. The findings suggest that during early adolescence, when children make the transition to secondary school, self-control declines. This is particularly the case for those experiencing puberty earlier than their peers. Parent warmth influences the trajectory of self-control during this period.

Childhood Reports of Food Neglect and Impulse Control Problems and Violence in Adulthood

Food insecurity and hunger during childhood are associated with an array of developmental problems in multiple domains, including impulse control problems and violence. Unfortunately, extant research is based primarily on small convenience samples and an epidemiological assessment of the hunger-violence link is lacking. The current study employed data from Wave 1 (2001-2002) and Wave 2 (2004-2005) of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). The NESARC is a nationally representative sample of non-institutionalized U.S. residents aged 18 years and older. Participants who experienced frequent hunger during childhood had significantly greater impulsivity, worse self-control, and greater involvement in several forms of interpersonal violence. These effects were stronger among whites, Hispanics, and males. The findings support general theoretical models implicating impulse control problems as a key correlate of crime and violence and add another facet to the importance of ameliorating food neglect in the United States.

Unpacking externalising problems: negative parenting associations for conduct problems and irritability

BACKGROUND

Reciprocal associations between negative parenting and child externalising problems are well documented, but measures commonly include child irritability, masking potential distinct associations for irritability and conduct problems.

AIMS

To illuminate links between negative parenting, child conduct problems and irritability over time.

METHOD

A cross-lagged monozygotic (MZ) twin differences design was used in a UK sample (3154 twin pairs) at 4, 7 and 9 years.

RESULTS

Within-pair MZ differences in negative parenting were found to relate longitudinally to differences in conduct problems and irritability. Of note, negative parenting at age 7 was found to relate particularly to increased irritability at 9 years.

CONCLUSIONS

Once genetics are taken into account, irritability in middle childhood may be particularly vulnerable to negative parenting, suggesting support for its malleability to parent-based intervention.

Child Sexual Abuse, Sexual Anxiety, and Sexual Satisfaction: The Role of Self-Capacities

Research indicates that child sexual abuse produces lasting alterations in interpersonal relatedness, identity, and affect regulation, often referred to as self-capacity disturbance. Child sexual abuse also has been shown to negatively impact sexual functioning. This study examined the role of altered self-capacities in mediating the relationship between child sexual abuse and sexual responses. Path analysis revealed that child sexual abuse was related to sexual anxiety and decreased sexual satisfaction through its association with reduced self-awareness and a propensity to be involved in difficult interpersonal relationships.

Wirksamkeit elternzentrierter Interventionen bei Kindern im Alter von zwei bis zwölf Jahren

Mittels eines systematischen Reviews von 68 Meta-Analysen und Übersichtsartikeln wird überprüft, welche elternzentrierten Interventionen für Kinder im Alter von zwei bis zwölf Jahren wirksam sind und welche psychischen Störungen effektiv behandelt werden können. Insgesamt zeigte sich, dass ein enger Einbezug der Eltern in die Behandlung der Kinder mit internalisierenden Störungen (v. a. bei jüngeren Kindern) sinnvoll ist. Hierbei scheinen vor allem kognitiv-behaviorale Ansätze mit Elterneinbezug wirksam zu sein. Hinsichtlich externalisierender Verhaltensprobleme erreichen behaviorale Elterntrainings neben einer Reduktion der Verhaltensprobleme auch positive Effekte auf Erziehungsverhalten und das elterliche psychische Wohlbefinden. Besonders behaviorale elternzentrierte Interventionen, deren Wirksamkeit nachgewiesen ist, sollten künftig häufiger angewendet werden und eine Möglichkeit zur Abrechnung über die Krankenkassen geschaffen werden.

The Triple P-Positive Parenting Program: a systematic review and meta-analysis of a multi-level system of parenting support

This systematic review and meta-analysis examined the effects of the multilevel Triple P-Positive Parenting Program system on a broad range of child, parent and family outcomes. Multiple search strategies identified 116 eligible studies conducted over a 33-year period, with 101 studies comprising 16,099 families analyzed quantitatively. Moderator analyses were conducted using structural equation modeling. Risk of bias within and across studies was assessed. Significant short-term effects were found for: children's social, emotional and behavioral outcomes (d=0.473); parenting practices (d=0.578); parenting satisfaction and efficacy (d=0.519); parental adjustment (d=0.340); parental relationship (d=0.225) and child observational data (d=0.501). Significant effects were found for all outcomes at long-term including parent observational data (d=0.249). Moderator analyses found that study approach, study power, Triple P level, and severity of initial child problems produced significant effects in multiple moderator models when controlling for other significant moderators. Several putative moderators did not have significant effects after controlling for other significant moderators. The positive results for each level of the Triple P system provide empirical support for a blending of universal and targeted parenting interventions to promote child, parent and family wellbeing.

The BDNF-Val66Met polymorphism modulates parental rearing effects on adult psychiatric symptoms: a community twin-based study

PURPOSE

To test whether firstly, different parental rearing components were associated with different dimensions of psychiatric symptoms in adulthood, secondly BDNF-Val66Met polymorphism moderated this association and thirdly, this association was due to genetic confounding.

METHOD

Perceived parental rearing according to Parental Bonding Instrument (PBI), psychiatric symptoms evaluated with the Brief Symptom Inventory (BSI) and the BDNF-Val66Met polymorphism were analyzed in a sample of 232 adult twins from the general population.

RESULTS

In the whole sample, paternal care was negatively associated with depression. Maternal overprotection was positively associated with paranoid ideation, obsession-compulsion and somatization. Gene-environment interaction effects were detected between the BDNF-Val66Met polymorphism and maternal care on phobic anxiety, paternal care on hostility, maternal overprotection on somatization and paternal overprotection also in somatization. In the subsample of MZ twins, intrapair differences in maternal care were associated with anxiety, paranoid ideation and somatization.

CONCLUSIONS

Met carriers were, in general, more sensitive to the effects of parental rearing compared to Val/Val carriers in relation to anxiety and somatization. Contra-intuitively, our findings suggest that high rates of maternal care might be of risk for Met carriers regarding anxiety. Results from analyses controlling for genetic confounding were in line with this finding.

Genes of experience: explaining the heritability of putative environmental variables through their association with behavioural and emotional traits

An increasing body of evidence shows that many ‘environmental’ measures are heritable, indicating genetic involvement in environmental exposure (or gene–environment correlation). In the present study we attempt to clarify why three such ‘environmental’ measures (maternal negativity, paternal negativity and negative life events) are consistently found to be heritable. Through multivariate genetic analysis of a sample of adolescent twins from the UK we show that the heritability of these putative environmental measures can be explained via their association with five behavioural phenotypes: oppositionality, delinquency, physical aggression, depression and anxiety. This is consistent with the notion that being genetically susceptible to certain behavioural difficulties could lead to exposure to certain life events, and this may account for the reported heritability of ‘environmental’ measures. Results are discussed in the context of possible active, evocative and passive gene–environment correlations.
