Trajectories of Executive Functions and ADHD Symptoms in Preschoolers and the Role of Negative Parental Discipline.

In the present study, we investigated whether the longitudinal growth trajectories of executive functions (EF) and Attention-Deficit/Hyperactivity Disorder (ADHD) symptoms are related. In addition, we investigated whether negative discipline moderated these longitudinal relations. The sample consisted of predominantly clinically referred preschoolers (N = 248, age 42-66 months at Time 1; 79.0% boys). Assessment occurred three times: at baseline, at 9 months, and at 18 months. EF was assessed with five EF tasks. ADHD symptoms (Child Behavior Checklist 1.5-5) were reported by parents. Groups of medium to high and low negative discipline were based on mother- and father-reports (Parenting Practices Inventory). Growth curve models showed that EF generally increased and ADHD symptoms generally decreased over time. Parallel process models showed that there was no relation between the change in EF and the change in ADHD symptoms over time, suggesting no co-development. However, higher EF at baseline was related to lower ADHD symptoms at baseline. This was irrespective of whether children were exposed to high or low negative discipline. Overall, the results suggest that, while EF and ADHD symptoms are related, they develop independently across the preschool years.

Inhibitory Control Across the Preschool Years: Developmental Changes and Associations with Parenting.

The normative developmental course of inhibitory control between 2.5 and 6.5 years, and associations with maternal and paternal sensitivity and intrusiveness were tested. The sample consisted of 383 children (52.5% boys). During four annual waves, mothers and fathers reported on their children's inhibitory control using the Children's Behavior Questionnaire. During the first wave, mothers' and fathers' sensitivity and intrusiveness were observed and coded with the Emotional Availability Scales. Inhibitory control exhibited partial scalar invariance over time, and increased in a decelerating rate. For both mothers and fathers, higher levels of sensitivity were associated with a higher initial level of children's inhibitory control, whereas higher levels of intrusiveness predicted a slower increase in children's inhibitory control.

The role of parental self-regulation and household chaos in parent-toddler interactions: A time-series study.

Various studies have reported that parental self-regulation is inversely related to negative parenting practices, especially in relatively calm households. These studies have focused on general tendencies of parents over longer periods of time. In the current time-series study, we extended previous work by focusing on the moment-to-moment processes in parent-child interactions that may explain associations between parental self-regulation, household chaos, and negative parenting practices. In a sample of 62 parent-toddler dyads (83.87% mothers), we tested whether observed contingent negative responses to child noncompliance (i.e., reactive negative parenting) could be predicted by the interaction between parental self-regulation and household chaos. Additionally, we examined whether two indicators of parental self-regulation, self-reported effortful control and task-based executive functioning, had similar associations with reactive negative parenting. Reactive negative parenting was assessed during clean up and was calculated as parents' propensity to show negative parenting practices immediately after their child showed noncompliance. We found that lower parental self-regulation predicted more reactive negative parenting practices in moderately chaotic households. Associations were similar regardless of whether self-regulation was operationalized as effortful control or executive functioning. The findings demonstrate that less regulated parents may benefit from a home situation that is tidy, calm, and characterized by routine in order to remain neutral in situations in which their toddler is noncompliant.

It takes two: Infants' moderate negative reactivity and maternal sensitivity predict self-regulation in the preschool years.

The aim of this longitudinal study was to examine the association of infant fussing and crying with self-regulation in toddlerhood and the preschool years, as well as the moderating role of maternal sensitivity therein. When children (n = 149, 53.69% boys) were 6 months old, parents reported on their fussing and crying using a cry diary, and maternal sensitivity was coded during a novel toy procedure. Children participated in various tasks to assess self-regulation in toddlerhood (18 months) and the preschool years (4.5 years). Results indicated that the relation between infant fussing and preschool self-regulation took the shape of an inverted U, but only for children of highly sensitive mothers. For infants of less sensitive mothers, fussing was not related to later self-regulation. Crying was unrelated to preschool self-regulation. Neither fussing, crying, nor maternal sensitivity predicted self-regulation in toddlerhood. The findings support the optimal arousal theory, by demonstrating that for infants of highly sensitive mothers, moderate amounts of low intensity negative reactivity are associated with enhanced self-regulation in the preschool years.

General Psychopathology and Dysregulation Profile in a Longitudinal Community Sample: Stability, Antecedents and Outcomes.

The general factor of psychopathology (GP, or p factor) and the Dysregulation Profile (DP) are two conceptually similar, but independently developed approaches to understand psychopathology. GP and DP models and their stability, antecedents and outcomes are studied in a longitudinal sample of 1073 children (49.8% female). GP and DP models were estimated at ages 8 and 14 years using the parent-reported Child Behavior Checklist (CBCL) and Youth Self Report (YSR). Early childhood antecedents and adolescent outcomes were derived using a multi-method multi-informant approach. Results showed that the general GP and DP had similar key symptoms and were similarly related to early-childhood antecedents (e.g., lower effortful control, higher maternal depression) and adolescent outcomes (e.g., reduced academic functioning, poorer mental health). This study demonstrates that GP and DP are highly similar constructs in middle childhood and adolescence, both describing a general vulnerability for psychopathology with (emotional) dysregulation at its core. Scientific integration of these approaches could lead to a better understanding of the structure, antecedents and outcomes of psychopathology.

Individual differences in visual attention and self-regulation: A multimethod longitudinal study from infancy to toddlerhood.

Given the importance of self-regulation for a broad range of developmental outcomes, identifying reliable precursors of self-regulation early in development is important for early prevention of developmental problems. The aim of this study was to examine whether three visual attention measures (fixation duration, variation in fixation duration, and disengagement) in infancy (9.10-11.43 months of age) predicted effortful control and compliance in toddlerhood (26.71-31.80 months). The sample consisted of 74 children (50% boys). In infancy, two eye-tracking tasks were conducted: a visual search task to assess fixation duration and variation in fixation duration (n = 58) and the gap-overlap task to assess disengagement (n = 49). In toddlerhood, children's effortful control (n = 65) and compliance (n = 65) were assessed by parent reports and observed during a delay of gratification task and a cleanup session together with the parents, respectively. Using full information maximum likelihood to account for missing data, multiple regression analyses revealed that, when all three measures of visual attention were taken into account, longer fixations and less variation in fixation duration in infancy predicted better effortful control. Disengagement did not predict effortful control. Compliance in toddlerhood was not predicted by any of the visual attention measures. These findings may indicate that visual attentional measures in infancy predict relatively independent forms of self-regulation in toddlerhood. Future studies are necessary to elucidate the mechanisms that underlie the association between (variation in) fixation duration in infancy and effortful control in toddlerhood.

The Dysregulation Profile in middle childhood and adolescence across reporters: factor structure, measurement invariance, and links with self-harm and suicidal ideation.

Recently, a phenotype of severe dysregulation, the Dysregulation Profile (DP), has been identified. DP consists of elevated scores on the Anxious/Depressed (AD), Aggressive Behavior (AGG) and Attention Problems (AP) scales of the Child Behavior Checklist (CBCL), Teacher Report Form (TRF), or Youth Self Report (YSR). A drawback in current research is that DP has been conceptualized and operationalized in different manners and research on the factor structure of DP is lacking. Therefore, we examined the factor structure of DP across multiple reporters, measurement invariance across gender, parents, and time, as well as links between DP and self-harm and suicidal ideation. Data from a large community sample were used (N = 697), covering middle childhood (Mage = 7.90, (SD = 1.16) and adolescence (Mage = 13.93, SD = 1.14). Mothers, fathers, teachers, and youth themselves reported on children's emotional and behavioral problems using the CBCL, TRF, and YSR. Results indicated that in middle childhood and in adolescence, a bifactor model with a general factor of Dysregulation alongside three specific factors of AD, AGG, and AP fitted best, compared to a second-order or one-factor model. The model showed good fit for mother, father, teacher, and youth reports and showed invariance across gender, parents and time. Youth, mother, and father reported Dysregulation was uniquely and positively related to adolescent-reported self-harm and suicidal ideation. The DP is best conceptualized as a broad dysregulation syndrome, which exists over and above anxiety/depression, aggression, and attention problems as specific problems. The bifactor model of DP explains the uniqueness and interrelatedness of these behavioral problems and can help explaining shared and non-shared etiology factors. The exclusive link between the general dysregulation factor and adolescents' self-harm and suicidal ideation further established the clinical relevance of the bifactor model.
