Diagnostic assessment of attention-deficit/hyperactivity disorder (ADHD) in children necessarily involves subjective judgements about the severity, frequency, and impact of symptoms on the part of parents, teachers, and clinicians. Thus, it is possible that parent and teacher ratings may be discrepant as a function of child and adult respondent race, adult role (i.e., parent or teacher), and environmental context (e.g., classroom vs. home). In order to fully understand racial differences in ADHD symptom ratings, it is important to disentangle the relative contributions of these factors. This commentary discusses the results of the Kang and Harvey (Journal of Abnormal Child Psychology,2019) study in relation to race, role, and context. Specific contributions of this study as well as unanswered questions to consider when interpreting their findings are delineated. Recommendations for future research to investigate the relative contributions of race, role, and context in accounting for racial differences in parent-teacher ADHD symptom ratings along with implications for assessment practice are discussed.

Stress is a common experience that can spillover into parenting, which in turn has important implications for child behavior. Parents' executive functioning (EF) may buffer the association between feelings of stress and parenting. However, using lower socioeconomic status (SES) and household chaos as indicators of stress, research has demonstrated inconsistent patterns with regard to this moderating role of EF. This study's first aim examined the moderating role of maternal EF on the associations between SES and household chaos, and harsh parenting. The second aim investigated the effects of experimentally induced stress on harsh parenting and whether maternal EF moderated these effects. A final sample of 101 mothers of 6 to 10-year-old children participated by completing measures of EF, household chaos, SES, and harsh parenting. Additionally, mothers were randomly assigned to either a stress group or a control group. Throughout the stress (or control) induction, mothers rated their harsh parenting in response to child misbehavior vignettes. Findings revealed that stronger EF reduced the association between household chaos and harsh parenting. There were no significant effects of SES or experimentally induced stress on harsh parenting, and EF was not a significant moderator for these stressors. These results highlight the buffering role of EF for more chronic stressors such as household chaos. SES and more acute stress, as manipulated by the TSST, at least in the current sample, may be less relevant.

Evidence-based behavioral therapies for children with disruptive and challenging behavior rarely yield immediate improvements in behavior. For caregivers participating in behavioral therapies, the benefits from these efforts are seldom visible until after substantial time commitments. Delays associated with relief from challenging behavior (i.e., improved behavior) can influence how caregivers decide to respond to instances of problem behavior, and in turn, their continued commitment (i.e., integrity, adherence) to treatments that require long-term implementation to produce improvements in child behavior. This study applied delay discounting methods to evaluate how delays affected caregiver preferences related to options for managing their child's behavior. Specifically, methods were designed to evaluate the degree to which caregiver preferences for a more efficacious, recommended approach was affected by delays (i.e., numbers of weeks in treatment). That is, methods evaluated at which point caregivers opted to disregard the optimal, delayed strategy and instead elected to pursue suboptimal, immediate strategies. Results indicated that caregivers regularly discounted the value of the more efficacious treatment, electing to pursue suboptimal approaches when delays associated with the optimal approach grew larger. Caregivers demonstrated similar patterns of suboptimal choice across both clinical (i.e., intervention) and non-clinical (i.e., monetary) types of decisions. These findings are consistent with research that has highlighted temporal preferences as an individual factor that may be relevant to caregiver adherence to long-term evidence-based treatments and encourage the incorporation of behavioral economic methods to better understand caregiver decision-making.

Despite replicated evidence for working memory deficits in youth with ADHD, no study has comprehensively assessed all three primary 'working' subcomponents of the working memory system in these children. Children ages 8-13 with (n = 45) and without (n = 41) ADHD (40% female; M_age = 10.5; 65% Caucasian/Non-Hispanic) completed a counterbalanced battery of nine tasks (three per construct) assessing working memory reordering (maintaining and rearranging information in mind), updating (active monitoring of incoming information and replacing outdated with relevant information), and dual-processing (maintaining information in mind while performing a secondary task). Detailed analytic plans were preregistered. Bayesian t-tests indicated that, at the group level, children with ADHD exhibited significant impairments in working memory reordering (BF₁₀ = 4.64 × 10⁵; d = 1.34) and updating (BF₁₀ = 9.49; d = 0.64), but not dual-processing (BF₀₁ = 1.33; d = 0.37). Overall, 67%-71% of youth with ADHD exhibited impairment in at least one central executive working memory domain. Reordering showed the most ADHD-related impairment, with 75% classified as below average or impaired, and none demonstrating strengths. The majority of children with ADHD (52%-57%) demonstrated average or better abilities in the remaining two domains, with a notable minority demonstrating strengths in updating (8%) and dual-processing (20%). Notably, impairments in domain-general central executive working memory, rather than individual subcomponents, predicted ADHD severity, suggesting that common rather than specific working memory mechanisms may be central to understanding ADHD symptoms. These impairment estimates extend prior work by providing initial evidence that children with ADHD not only exhibit heterogeneous profiles across cognitive domains but also exhibit significant heterogeneity within subcomponents of key cognitive processes.

Despite being one of the least studied components of social influence, positive peer associations have much to offer social learning theories of crime. The purpose of the current investigation was to determine whether positive peer associations moderate the peer influence effect central to social learning theory. Data provided by 3869 (1970 boys, 1899 girls) members of the Longitudinal Study of Australian Children (LSAC) were used to test the hypothesis that positive peer associations interact with components of peer influence to protect adolescents against future delinquency. A simple mediation analysis confirmed the existence of a significant indirect effect running from peer delinquency, to low empathy, to participant delinquency. When positive peer associations were added to the model as moderators, they achieved a significant negative moderating effect on the peer delinquency-low empathy path and a significant positive moderating effect on the low empathy-participant delinquency path. In this study, positive peer associations increased empathy in children with fewer delinquent peer associations and decreased offending in children with lower levels of empathy. Given evidence of their ability to inhibit negative peer influence and promote empathy in the service of reduced delinquency, positive peer associations deserve more attention from social learning theories of crime than they have thus far received.

Despite trends indicating worsening internalizing problems, characterized by anxiety and depression, there is dearth of research examining gender differences in developmental trajectories of internalizing problems from early childhood to adolescence. Drawing on the UK Millennium Cohort Study (n = 17,206, 49% female), this study examines trajectories of parent-reported, clinically-meaningful (reflecting the top 10%) internalizing problems from ages 3 to 14 years and their early predictors and adolescent outcomes. Group-based modelling revealed three trajectories when examining boys and girls together, but there were significant gender differences. When examining boys and girls separately, four trajectories were identified including two relatively stable trajectories showing either high or low probabilities of internalizing problems. An increasing trajectory was also found for both boys and girls, showing an increasing probability of internalizing problems which continued to rise for girls, but levelled off for boys from age 11. A decreasing trajectory was revealed for boys, while a moderate but stable trajectory was identified for girls. Boys and girls in the increasing and high probability groups were more likely to report a number of problematic outcomes including high BMI, self-harm, low mental wellbeing, depressive symptoms, and low educational motivation than the low group. Girls on the increasing trajectory also reported more cigarette and cannabis use and early sexual activity at age 14 compared to girls on the low trajectory. Findings suggest that intervention strategies take a systemic view, targeting not only internal feelings, but also behaviours potentially associated with later negative outcomes.

Obsessive-compulsive disorder (OCD) and trichotillomania (hair pulling disorder, HPD) are both considered obsessive-compulsive and related disorders due to some indications of shared etiological and phenomenological characteristics. However, a lack of direct comparisons between these disorders, especially in pediatric samples, limits our understanding of divergent versus convergent characteristics. This study compared neurocognitive functioning between children diagnosed with OCD and HPD. In total, 21 children diagnosed with HPD, 40 diagnosed with OCD, and 29 healthy controls (HCs), along with their parents, completed self-/parent-report measures and a neurocognitive assessment battery, which included tasks of inhibitory control, sustained attention, planning, working memory, visual memory, and cognitive flexibility. A series of analyses of variance (or covariance) indicated significant differences between groups on tasks examining planning and sustained attention. Specifically, children in both the OCD and HPD groups outperformed HCs on a task of planning. Further, children with OCD underperformed as compared to both the HPD and HC groups on a task of sustained attention. No between group differences were found with respect to tasks of reversal learning, working memory, spatial working memory, visual memory, or inhibitory control. The implications these findings may have for future, transdiagnostic work, as well as limitations and future directions are discussed.

Childhood conduct problems have been associated with reduced autonomic arousal to negative cues indicative of an insensitivity to aversive stimuli, with mixed evidence in response to positive cues. Autonomic arousal to affective stimuli has traditionally been measured through galvanic skin responses and heart-rate, despite evidence that pupillometry is more reliable and practically beneficial (i.e., no wires are attached to the participant). The current study is the first to examine abnormal pupillary responsivity to affective stimuli as a biomarker for childhood conduct problems. We measured pupil reactivity to negative, positive and neutral images in 131 children aged 4-7 years, who were referred by their teachers for being at risk of future psychopathology. We assessed relationships between pupil response to the images and teacher-rated scores on the Strengths and Difficulties Questionnaire (SDQ), which indexed child conduct problems and their overlapping emotional, behavioural and social difficulties. Reduced pupil dilation to negative images was associated with significantly increased conduct, hyperactivity, emotional and peer problems, as well as reduced prosocial behaviour. Composite scores for disruptive behaviour and emotional difficulties both uniquely predicted blunted pupil response to negative threat stimuli; there were no relations with pupil responses to positive images. These findings highlight that blunted pupil responsivity to negative stimuli serves as a biomarker for early disruptive behavioural problems and affective difficulties. Pupillometry offers an inexpensive, fast and non-intrusive measure to help identify children who are showing early disruptive behaviour or experiencing affective difficulties, which can provide opportunities for preventative intervention to avoid further psychopathology.

Military parents' combat-related posttraumatic stress disorder (PTSD) symptoms have been linked to poor parenting and child maladjustment. Emotion regulation (ER) difficulties are thought to underlie PTSD symptoms, and research has begun to link parental ER to parenting behaviors. Little empirical evidence exists regarding whether fathers' ER is associated with child adjustment and what may be the underlying mechanism for this association. This study investigated whether deployed fathers' ER was associated with child emotional and behavioral problems, and whether the associations were mediated by coercive parenting behaviors. The sample consisted of 181 deployed fathers with non-deployed female partners and their 4- to 13-year-old children. Families were assessed at three time points over 2 years. ER was measured using a latent construct of fathers' self-reports of their experiential avoidance, trait mindfulness, and difficulties in emotion regulation. Coercive parenting was observed via a series of home-based family interaction tasks. Child behaviors were assessed through parent- and child-report. Structural equation modeling revealed that fathers with poorer ER at baseline exhibited higher coercive parenting at 1-year follow-up, which was associated with more emotional and behavioral problems in children at 2-year follow-up. The indirect effect of coercive parenting was statistically significant. These findings suggest that fathers' difficulties in ER may impede their effective parenting behaviors, and children's adjustment problems might be amplified as a result of coercive interactions. Implications for the role of paternal ER on parenting interventions are discussed.

Adolescents with Attention-Deficit/Hyperactivity Disorder (ADHD) demonstrate increased levels of real-life risk-taking behavior like substance abuse and reckless behavior in traffic, which potentially originates in decision-making deficits. Using experimental gambling tasks, the current study investigated three potential underlying mechanisms: (1) risky vs. suboptimal decision making, (2) the complexity of decision-making strategies and (3) the influence of feedback. Participants were 181 male adolescents (81 ADHD, 100 Typically Developing (TD); M_age = 15.1 years). First, we addressed a common confound in many gambling tasks by disentangling risk seeking from suboptimal decision making, and found that ADHD-related decision-making deficits do not originate in increased risk seeking but in suboptimal decision making. Second, we assessed decision-making strategies with a Bayesian latent mixture analysis and found that ADHD-related decision-making deficits are characterized by the use of less complex strategies. That is, adolescent boys with ADHD, relative to TD adolescent boys, less often adopted strategies in which all characteristics relevant to make an optimal decision were integrated. Third, we administered two gambling task conditions with feedback in which adolescents experience the outcomes of their decisions and found that adolescents with ADHD performed worse relative to TD adolescents on both conditions. Altogether, this set of studies demonstrated consistent decision-making deficits in adolescent boys with ADHD: The use of less complex decision-making strategies may cause suboptimal decision making, both in situations with and without direct feedback on performance.
