Emotions or cognitions first? Longitudinal relations between executive functions and emotion regulation in childhood.

Executive functions and emotion regulation develop from early childhood to adolescence and are predictive of important psychosocial outcomes. However, despite the correlation between the two regulatory capacities, whether they are prospectively related in school-aged children remains unknown, and the direction of effects is uncertain. In this study, a sample drawn from two birth cohorts in Norway was biennially examined between the ages of 6 and 14 (n = 852, 50.1% girls, 93% Norwegian). Parents completed the Emotion Regulation Checklist, and teachers completed the Behavior Rating Inventory of Executive Function. A random intercept cross-lagged panel model revealed that improved emotion regulation predicted increased executive functioning to the same extent throughout development, whereas enhanced executive functioning was unrelated to future changes in emotion regulation.

Association of anxiety and depression to headache, abdominal- and musculoskeletal pain in children.

The comorbidity between recurrent pain, anxiety, and depression among children is frequent and well documented. However, only a few studies of the predictive effect of anxiety and depression on pain have adjusted for symptoms of the other disorder when examining the respective relations to different pain locations, rendering the unique contribution from anxiety and depression undetermined. In the current investigation we explore the strength of associations between pain at different locations with symptoms of anxiety and depression in a community sample of 10-year-old children (n = 703). The children were interviewed about the frequency of pain during the last 3 months. Parents and children were interviewed separately about symptoms of anxiety and depression using a semi-structured diagnostic interview. Results of three multivariate regression models for each of headache, abdominal and musculoskeletal pain revealed that depression was associated with musculoskeletal pain and headache, whereas anxiety was not. The associations for depression were not significantly stronger compared to anxiety. Gender-specific models found that depression was related to headache only among girls, but the association was not statistically different compared to boys. These results may, in turn, influence our interpretation of different forms of pain in children, with less weight given to abdominal symptoms viewed as a strong correlate with psychological problems, compared to for instance headache. The results provided no clear support for neither a differential relationship between anxiety and pain and depression and pain nor gender differences.

Longitudinal relations between impaired executive function and symptoms of psychiatric disorders in childhood.

BACKGROUND: Malfunctioning of executive functions correlates with psychopathology in children. However, the directionality, the extent to which the relation varies for various disorders, and whether prospective relations afford causal interpretations are not known. METHODS: A community sample of Norwegian children (n = 874) was studied biennially from the age of 6 to 14 years. Executive functions were assessed using the Behavior Rating Inventory of Executive Function Teacher-report and symptoms of psychopathology were assessed using the Preschool Age Psychiatric Assessment (age 6; parents) and Child and Adolescent Psychiatric Assessment (ages 8-14; children and parents). Prospective reciprocal relations were examined using a random intercept cross-lagged panel model that adjusts for all unobserved time-invariant confounders. RESULTS: Even when time-invariant confounders were accounted for, reduced executive functions predicted increased symptoms of depressive disorders, anxiety disorders, attention-deficit hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), and conduct disorder (CD) 2 years later, even when previous changes in these symptoms were adjusted for. The level of prediction (B = .83, 95% CI [.37, 1.3]) was not different for different disorders or ages. Conversely, reduced executive functions were predicted by increased symptoms of all disorders (B = .01, 95% CI [.01, .02]). CONCLUSIONS: Reduced executive functioning may be involved in the etiology of depression, anxiety, ADHD, and ODD/CD to an equal extent. Moreover, increased depression, anxiety, ADHD, and ODD/CD may negatively impact executive functioning.

Association Between Objectively Measured Sleep Duration and Symptoms of Psychiatric Disorders in Middle Childhood.

Importance: The long-term association between sleep duration and mental health in children is currently unknown. Objective: To investigate the prospective associations between sleep duration and symptoms of emotional and behavioral disorders at ages 6, 8, 10, and 12 years. Design, Setting, and Participants: This population-based cohort study obtained data from the Trondheim Early Secure Study in Trondheim, Norway. A representative, stratified random sample of children born between January 1, 2003, and December 31, 2004, were invited to participate. Participants were followed up biennially from age 4 years (2007-2008) to 12 years (2013-2014). Data analysis was conducted from January 2, 2019, to May 28, 2019. Main Outcomes and Measures: Sleep duration was assessed with 1 week of continuous use of a triaxial accelerometer. Symptoms of emotional (anxiety and depression) and behavioral (oppositional defiant, conduct, and attention-deficit/hyperactivity) disorders were measured by semistructured clinical interviews (using the Preschool Age Psychiatric Assessment and the Child and Adolescent Psychiatric Assessment) with parents (at all ages) and children (from age 8 years). Results: The analytical sample comprised 799 children (mean [SD] age at time point 2, 6.0 [0.2] years; 405 [50.7%] boys; and 771 [96.5%] Norwegian). Shorter sleep duration at age 6 years (ß [unstandardized regression coefficient] = -0.44; 95% CI, -0.80 to -0.08; P = .02) and 8 years (ß = -0.47; 95% CI, -0.83 to -0.11; P = .01) forecasted symptoms of emotional disorders 2 years later. Comparatively short sleep duration at age 8 years (ß = -0.65; 95% CI, -1.22 to -0.08; P = .03) and 10 years (ß = -0.58; 95% CI, -1.07 to -0.08; P = .02) was associated with symptoms of behavioral disorders 2 years later among boys but not among girls at age 8 years (ß = -0.14; 95% CI,- 0.52 to 0.24; P = .48) or 10 years (ß = -0.05; 95% CI, = -0.49 to 0.40; P = .84). These associations were statistically significant among boys compared with girls at age 8 years (Δχ21 = 13.26; P < .001) and 10 years (Δχ21 = 10.25; P = .001). Symptoms of psychiatric disorders did not forecast sleep duration at any age. Conclusions and Relevance: This study found an association between short sleep duration and increased risk of future occurrence of emotional disorder symptoms in both boys and girls and between reduced sleep and behavioral disorder symptoms in boys. These results suggest that improving sleep in children may help protect against the development of symptoms of common psychiatric disorders and may be advantageous in the treatment of such disorders.

Parental predictors of children's executive functioning from ages 6 to 10.

According to prominent models of child development, parental factors may contribute to individual differences in children's executive functioning (EF). Here, we examine the relative importance of parents' socio-economic status, mental health, and parenting as predictors of EF development, drawing on a large (n = 1,070) community sample of Norwegian children who received biennial EF assessments from 6 to 10 years of age. We measure EF by means of the Behavior Rating Inventory of Executive Function. We assess parenting through observer ratings of parent-child interactions and parental mental health via the Beck Anxiety Inventory, Beck Depression Inventory, and Hopkins Symptom Checklist. When we adjust for all time-invariant unmeasured confounders, higher parental education predicts superior EF development, whereas harsh parenting forecasts poorer EF development. However, parenting does not mediate the effect of parental education. These results indicate that harsh parenting should be targeted in interventions aimed at improving EF. Statement of contribution What is already known on this subject? Parental factors seem to affect child development of executive functions (EF). Specifically, parental socio-economic status, mental health, and their parenting seem to influence the developmental course of child EF. What does this study add? To what degree the parental influence on EF development is likely to be driven by time-invariant factors, for example, genetics. The relative influence of positive and negative parenting on EF development.
