Neural Responses to Intranasal Oxytocin in Youths With Severe Irritability.

OBJECTIVE: The authors investigated the neural impact of intranasal oxytocin on emotion processing areas in youths with severe irritability in the context of disruptive mood and behavior disorders. METHODS: Fifty-two participants with severe irritability, as measured by a score ≥4 on the Affective Reactivity Index (ARI), with diagnoses of disruptive behavior disorders (DBDs) and/or disruptive mood dysregulation disorder (DMDD) were randomly assigned to treatment with intranasal oxytocin or placebo daily for 3 weeks. Assessments were conducted at baseline and at the end of the trial; the primary outcomes were measures of irritability on the ARI and ratings on the Clinical Global Impressions severity scale (CGI-S) focusing on DBD and DMDD symptoms, and secondary outcomes included the CGI improvement scale (CGI-I) and ratings of proactive and reactive aggressive behavior on the Reactive-Proactive Aggression Questionnaire. Forty-three participants (22 in the oxytocin group and 21 in the placebo group) completed pre- and posttreatment functional MRI (fMRI) scans with the affective Stroop task. RESULTS: Youths who received oxytocin showed significant improvement in CGI-S and CGI-I ratings compared with those who received placebo. In the fMRI data, blood-oxygen-level-dependent (BOLD) responses to emotional stimuli in the dorsomedial prefrontal cortex and posterior cingulate cortex were significantly reduced after oxytocin compared with placebo. These BOLD response changes were correlated with improvement in clinical severity. CONCLUSIONS: This study provides initial and preliminary evidence that intranasal oxytocin may induce neural-level changes in emotion processing in youths with irritability in the context of DBDs and DMDD. This may lead to symptom and severity changes in irritability.

The association between delinquent peer affiliation and disruptive behavior interacts with functional brain correlates of reward sensitivity: a biosocial interaction study in adolescent delinquents.

BACKGROUND: Affiliating with delinquent peers may stimulate the development of antisocial behavior, especially for adolescents who are sensitive to social rewards. The current study examines whether the association between delinquent peer affiliation (DPA) and disruptive behavior interacts with functional brain correlates of reward sensitivity in early onset male adolescents delinquents. METHODS: Childhood arrestees (n = 126, mean age = 17.7 [s.d. 1.6]) completed a DPA questionnaire, and participated in an fMRI study in which reward sensitivity was operationalized through responsiveness of the ventral striatum (VS), amygdala, and medial prefrontal cortex (mPFC) during the monetary incentive delay paradigm (reward anticipation and outcome). Symptoms of disruptive behavior disorders (DBD) were assessed through structured psychiatric interviews (Diagnostic Interview Schedule for Children) with adolescents. RESULTS: DPA had a main effect on DBD symptoms. Adolescents with high VS reward responses showed a stronger significant positive association between DPA and DBD symptoms compared to low VS responders. No evidence for an interaction effect was found for the amygdala and mPFC. Post-hoc analyses revealed the positive association between DPA and DBD was only present in males, with a diminishing effect as age increased. CONCLUSIONS: We found evidence for a biosocial interaction between DPA and reward sensitivity of the VS in relation to DBD symptom severity. This study provides the first evidence of an interaction effect between a brain mechanism and an environmental factor in relation to DBD symptoms, implying that susceptibility to influences of delinquent peers may intertwine with individual biological differences.

Comparing self-reported quality of life in youth with bipolar versus other disorders.

OBJECTIVES: This study benchmarks quality of life (QoL) of youth with bipolar disorder (BD) against healthy youth, youth with chronic medical conditions, and youth with other psychiatric disorders. The relative impacts of depressive, (hypo)manic, mixed, and externalizing symptoms on QoL are tested for youth with BD. METHOD: In total, 657 youth completed the Schedule for Affective Disorders and Schizophrenia for Children (KSADS), the KSADS depression and mania scales, the Parent General Behavior Inventory (PGBI), and the Child Behavior Checklist (CBCL). Youth-reported QoL was determined by the Revised Children Quality of Life Questionnaire (KINDL) and was compared to healthy youth, youth with chronic medical conditions, and youth with other psychiatric disorders. RESULTS: Youth with BD reported poorer QoL overall and on most subscales compared to healthy youth, youth with chronic medical conditions, youth with behavior disorders, and youth with other non-behavior/non-mood disorders. QoL in youth with BD did not differ significantly from QoL in youth with unipolar depression. Parent-report and interview-rated depressive symptoms were associated with decreases in Total QoL and all QoL subscales except Family. Externalizing symptoms were associated with decreases in Family QoL and increases in Friend QoL, and (hypo)manic symptoms were associated with increases in Emotional Well-Being QoL. CONCLUSIONS: Depressive symptoms may drive the decline in QoL causing youth with BD to rate their QoL worse than healthy youth, youth with chronic medical conditions, and youth with behavior disorders, but not worse than youth with unipolar depression.

Pediatric Off-label Antipsychotic Use for Attention-Deficit/Hyperactivity Disorder.

PURPOSE: Off-label antipsychotic use for behavioral symptoms in pediatric attention-deficit/hyperactivity disorder (ADHD) poses safety concerns, and evidence to support such use is limited. This study aims to investigate the risk of off-label antipsychotic use associated with comorbid disruptive behavior disorder (DBD) among a cohort of youth with ADHD. METHODS: A cohort study was conducted using IQVIA PharMetrics Plus for Academics data from 2007 to 2020. Youth 5 to 15 years of age at the index ADHD visit were included in the cohort. The index ADHD visit meets at least 1 of the following criteria: (1) 1 inpatient ADHD visit, (2) 2 outpatient ADHD visits within 90 days, or (3) an ADHD medication prescription fill within 30 days of an outpatient ADHD visit. We excluded youth who had a diagnosis of DBD or a US Food and Drug Administration (FDA)-approved indication for antipsychotics at baseline. Youth were followed up until antipsychotic initiation or were censored at a loss of coverage, receipt of an FDA-indicated diagnosis, or end of the study. A Cox proportional hazards regression model with DBD as a time-varying covariate estimated the hazard of antipsychotic use after the index ADHD visit. FINDINGS: Of 41,098 youth with ADHD who met the study criteria, 4557 were diagnosed with DBD during follow-up. The incidence of antipsychotic initiation was 19.6 (95% CI, 18.7- 20.5) per 1000 person-years. After adjustment for baseline covariates, the hazard ratio of antipsychotic initiation associated with DBD was 4.64 (95% CI, 4.15-5.18). IMPLICATIONS: Antipsychotic use among youth with ADHD is more likely in the presence of DBD, suggesting that an off-label use is for behavior problems.

The Efficacy of Parent Management Training With or Without Involving the Child in the Treatment Among Children with Clinical Levels of Disruptive Behavior: A Meta-analysis.

A systematic review and meta-analysis was conducted where we evaluated the effects of Parent Management Training (PMT), Parent-Child Interaction Therapy (PCIT) and PMT combined with child cognitive behavioral therapy (CBT) using data from 25 RCTs on children with clinical levels of disruptive behavior (age range 2-13 years). Results showed that PMT (g = 0.64 [95% CI 0.42, 0.86]) and PCIT (g = 1.22 [95% CI 0.75, 1.69]) were more effective than waiting-list (WL) in reducing parent-rated disruptive behavior, and PMT also in improving parental skills (g = 0.83 [95% CI 0.67, 0.98]) and child social skills (g = 0.49 [95% CI 0.30, 0.68]). PCIT versus WL had larger effects in reducing disruptive behavior than PMT versus WL. In the few studies found, the addition of child CBT to PMT did not yield larger effects than PMT or WL. These results support offering PMT to children with clinical levels of disruptive behavior and highlight the additional benefits of PCIT for younger ages.

Trends in antipsychotic use for youth with attention-deficit/hyperactivity disorder and disruptive behavior disorders.

PURPOSE: To examine trends in off-label antipsychotic use for youth with attention-deficit/hyperactivity disorder with and without a comorbid disruptive behavior disorder. METHOD: This cross-sectional study of annual trends from 2007 through 2015 used the IQVIA PharMetrics® Plus for Academics data. We identified 165 794 commercially-insured youth 3-18-year-old who had a diagnosis of attention-deficit/hyperactivity disorder and classified them into subgroups with and without disruptive behavior disorders comorbidities. Antipsychotic use, with or without a stimulant, was the primary dependent outcome. Logistic regression estimated the odds of antipsychotic use associated with comorbid attention-deficit/hyperactivity disorder and disruptive behavior disorders, adjusting for age, sex, study year, and other psychotropic use. RESULTS: Over 70% of the 165 794 youth with attention-deficit/hyperactivity disorder were 5-14-year-old and male, and 12% had disruptive behavior disorders. Antipsychotic prevalence, with or without a stimulant, was 4.4% in 2007 and 3.4% in 2015. Stimulants with antipsychotics increased significantly from 2007 to 2015 for females (19.5%-28.7%) and youth 15-18-year-old (25.9%-32.7%). Adjusting for age, sex, study year, and other psychotropic use, youth with a comorbid disruptive behavior had a 2.5 (95% CI: 2.3, 2.7) higher likelihood of receiving an antipsychotic than youth with attention-deficit/hyperactivity disorder and no comorbidities. CONCLUSIONS: Antipsychotic use was associated with comorbid disruptive behaviors in youth with attention-deficit/hyperactivity disorder. Off-label antipsychotic use has increased for females and older adolescents.

Clinician-Identified Factors in Success of Parent-Directed Behavioral Therapy for Children's Tantrums.

Disruptive behavior disorders (DBD) are the most common behavioral health problems in young American children. When not well-managed in early childhood, DBD can progress to lifetime mental health problems with personal, economic, as well as societal impacts. The evidence-based intervention of choice for DBD is outpatient parent-directed behavioral therapy (PDT). However, little is known about clinicians' perspectives on the factors influencing PDT's effectiveness in routine care. The current study directly assesses clinicians' perspectives on factors they believe impact PDT's success for disruptive behavior problems, in particular tantrums, at two outpatient behavioral therapy clinics specializing in PDT. In-depth interviews with 19 clinicians across three experience levels (doctoral intern, post-doctoral, licensed staff psychologist) were conducted and analyzed using qualitative methods. Two major themes were identified as enabling and limiting treatment success: (1) appointment attendance, (2) primary caregiver buy-in to treatment approach. Additional identified factors include caregiver's familial and social support, caregiver's physical and emotional capacities, complexity of the child's behavior problems, the extent to which the home environment can support positive changes, competing family/home demands, and care coordination among hospital programs. The primary factors identified by clinicians highlight the importance of fostering appointment attendance and parental psychoeducation that can be addressed by implementing multi-level administrative, training, and clinical initiatives to improve PDT's real-world effectiveness for DBD.

Incremental Validity of Multi-Method and Multi-Informant Evaluations in the Clinical Diagnosis of Preschool ADHD.

OBJECTIVES: This study investigated the discriminative validity of various single or combined measurements of electroencephalogram (EEG) data, Conners' Kiddie Continuous Performance Test (K-CPT), and Disruptive Behavior Disorder Rating Scale (DBDRS) to differentiate preschool children with ADHD from those with typical development (TD). METHOD: We recruited 70 preschoolers, of whom 38 were diagnosed with ADHD and 32 exhibited TD; all participants underwent the K-CPT and wireless EEG recording in different conditions (rest, slow-rate, and fast-rate task). RESULTS: Slow-rate task-related central parietal delta (1-4 Hz) and central alpha (8-13 Hz) and beta (13-30 Hz) powers between groups with ADHD and TD were significantly distinct (p < .05). A combination of DBDRS, K-CPT, and specific EEG data provided the best probability scores (area under curve = 0.926, p < .001) and discriminative validity to identify preschool children with ADHD (overall correct classification rate = 85.71%). CONCLUSIONS: Multi-method and multi-informant evaluations should be emphasized in clinical diagnosis of preschool ADHD.

Neural Responses to Fluoxetine in Youths with Disruptive Behavior and Trauma Exposure: A Pilot Study.

Objective: A preliminary investigation of the impact of a serotonergic agent (fluoxetine) on symptom profile and neural response in youths with disruptive behavior disorders (DBDs) and a history of trauma exposure. Methods: There were three participant groups: (i) Youths with DBDs and trauma exposure who received fluoxetine treatment for 8 weeks (n = 11); (ii) A matched group of youths with DBDs and trauma exposure who received routine regular follow-up in an outpatient clinic (n = 10); and (iii) Typically developing youths (n = 18). All participants conducted an expression processing functional magnetic resonance imaging task twice, 8 weeks apart: (pretreatment and post-treatment for youths with DBDs). Results: Youths with DBDs and trauma exposure who received fluoxetine treatment compared to the other two groups showed: (i) significant improvement in externalizing, oppositional defiant disorder, irritability, anxiety-depression, and trauma-related symptoms; (ii) as a function of fearful expression intensity, significantly decreased amygdala response and increased recruitment of regions implicated in top-down attention control (insula cortex, inferior parietal lobule, and postcentral gyrus) and emotional regulation (ventromedial prefrontal cortex [vmPFC]); and (iii) correlation between DBD/irritability symptom improvement and increased activation of top-down attention control areas (inferior parietal lobule, insula cortex, and postcentral gyrus) and an emotion regulation area (vmPFC). Conclusions: This study provides preliminary evidence that a serotonergic agent (fluoxetine) can reduce disruptive behavior and mood symptoms in youths with DBDs and trauma exposure and that this may be mediated by enhanced activation of top-down attention control and emotion regulation areas (inferior parietal lobule, insula cortex, and vmPFC).

The Efficacy of Parent Training Interventions for Disruptive Behavior Disorders in Treating Untargeted Comorbid Internalizing Symptoms in Children and Adolescents: A Systematic Review.

Disruptive behavior disorders (DBDs) are among the primary reasons for child and youth referrals to mental health services and are linked to poor adult outcomes including antisocial behavior disorder. Research indicates a high incidence of internalizing problems in those with DBDs and those who have DBDs with cooccurring internalizing problems may have more severe later outcomes. Interventions targeted at internalizing symptoms have been found to also reduce comorbid externalizing problems. The impact of treatments for DBDs on comorbid internalizing disorders is not known. Databases PsycINFO, EMBASE and MEDLINE were systematically searched based on the Cochrane guidelines for systematic reviews. Records were independently reviewed by two reviewers. 12 papers were deemed eligible. A quality assessment of the selected studies was conducted independently by both reviewers. The 12 studies included 1334 young people with a mean age of 5 years. The parent training interventions assessed were the Incredible Years (6/12 studies), Triple-P (5/12) and Tuning In To Kids (1/12). 11 of the 12 studies reported significant reductions in primary externalizing behavior problems and DBDs. 7 studies reported significant reductions in internalizing symptoms. Mechanisms of change, clinical implications and directions for future research are discussed.

Effect of relative age on childhood mental health: A cohort of 9,548,393 children and adolescents.

BACKGROUND: The effect of relative age on the diagnoses of attention deficit hyperactivity disorder (ADHD), disruptive behavior disorder (DD), anxiety disorder, and depressive disorder and the prescription for ADHD and antidepressant medications remains unclear. AIM: To clarify the impact of relative age in a school year with the diagnoses of ADHD, DD, anxiety disorder, and depressive disorder and the prescription for ADHD and antidepressant medications. METHODS: The annual cutoff birthdate for entry to school in Taiwan is August 31. The Taiwan National Health Insurance Research Database was used to enroll 9,548,393 children and adolescents aged 3-17 years during the study period (September 1, 2001, to August 31, 2011). The Poisson regression model was performed to examine the likelihood of receiving diagnoses of ADHD, DD, anxiety disorder, and depressive disorder, as well as the prescription of ADHD and antidepressant medications among children born in August (the youngest) and September (the oldest). RESULTS: Both boys and girls born in August had a higher risk of being diagnosed as having ADHD (odds ratio [OR] = boys: 1.65, girls: 1.80), DD (1.29, 1.45), anxiety disorder (1.49, 1.33), and depressive disorder (1.10, 1.10). Furthermore, children born in August were more likely to be prescribed ADHD medication (1.71, 1.72) and antidepressants (1.18, 1.09) compared with those born in September. DISCUSSION: Relative age, as an indicator of neurocognitive maturity, is a critical factor for the likelihood of being diagnosed as having ADHD, DD, anxiety disorder, and depressive disorder among children and adolescents.

Psychometric Properties of the Parent Cognition Scale in a Clinical Sample of Parents of Children With Disruptive Behavior.

The Parent Cognition Scale (PCS; Snarr, Slep, & Grande, 2009) is a self-report measure of parental attributions of child behavior that has demonstrated validity in community samples. However, its psychometric properties have not been examined in a clinical sample of parents of children with disruptive behavior. Examining the psychometric properties of the PCS in this population is important given research linking parent attribution with childhood disruptive behavior. The present study aimed to: (a) examine the psychometric properties of the PCS in a sample of parents whose children were clinic-referred for disruptive behavior problems; and (b) investigate the concurrent validity of the PCS and its factors using correlations with parent reports of children's emotional and behavioral difficulties, and parenting skills (i.e., discipline, supervision). A confirmatory factor analysis was run on 225 parents' responses on the PCS, and revealed that a two-factor structure of the PCS fit the data well. Significant correlations were found between Parent Causal Attributions (Factor 1) and parent-reported parenting difficulties. Child Responsible Attributions (Factor 2) were correlated with elevations in children's emotion, attention, and conduct difficulties. The results provide information on the utility of the PCS for parents of children with disruptive behavior and its potential clinical relevance.

Incidence and comorbidities of disruptive behavior disorders diagnosed in Finnish specialist psychiatric services.

PURPOSE: Disruptive behavior disorders (DBD), including oppositional defiant disorder (ODD) and conduct disorder (CD), are some of the most common psychiatric conditions in childhood. Despite this, there has been limited research on DBDs. We examined the incidence, comorbidity and gender differences of DBDs diagnosed by specialist services. METHOD: This was a nationwide register study of 570,815 children and adolescents born in 1996-2005. The 7050 individuals diagnosed with DBD by specialist healthcare services were matched to 26,804 controls. RESULTS: By the age of 15, the cumulative incidence of diagnosed DBDs was 3.5% for boys and 1.4% for girls. The yearly incidence rate increased for girls after 13 years of age, while the incidence for boys was relatively stable between 8 and 15 years of age. When we compared subjects born between 1996-1998 and 1999-2001, we found that by the age of 12, the cumulative incidence per 100 people had increased from 0.56 to 0.68 among girls and from 2.3 to 2.6 among boys. This indicated a minor increase in treated incidence. The parents of children diagnosed with DBDs had lower educational levels than the parents of controls. Children with DBD were also more likely to have been diagnosed with other psychiatric disorders. CONCLUSION: Although DBDs were 3.5 times more common among boys during the whole follow-up period, the yearly incidence during adolescence was fairly similar between boys and girls. DBD existed alongside various psychiatric disorders at a relatively young age and only a minor increase in treated incidence was found during childhood.

Psychometric Properties of the Child Attachment Interview in Italian Context: A Focus on Normative and Specific Clinical Groups in School-Aged Children.

While attachment assessments developed for infancy and adulthood are well established, no such gold standard measure exists for school years, where measures are not yet sufficiently robust. Nevertheless, the last decade has witnessed some progress in this field with the development of the Child Attachment Interview (CAI), a semistructured interview designed to access children's mental representations of their attachment relationships. This study aimed to test the validity and reliability of the CAI for an Italian population, using a normative group and a clinical group of disruptive behavior disorder and somatic symptom disorder patients. A total sample of 311 Italian children (213 normative and 98 clinical) aged 8 to 15 years completed a battery of measures assessing attachment, verbal IQ, and symptomatology. The psychometric properties of the CAI alongside other children (Kerns Security Scale, Inventory of Parent and Peer Attachment) and parents (Adult Attachment Interview) attachment measures in normative sample, as well as the distribution of attachment patterns in normative and clinical samples, were examined. The results revealed the CAI to have adequate interrater and test-retest reliability, as well as discriminant, and convergent validity. Significant differences in the CAI's distribution of attachment patterns for normative and specific clinical groups were found. Taken together, the findings show that the CAI Italian version is a reliable and valid measure for assessing attachment in school years and beyond.

Relationships between childhood maltreatment, impairment in executive functions and disruptive behavior disorders in a community sample of children.

Evidence points to an independent relationship among childhood maltreatment, impairments in executive functions (EF) and disruptive behavior disorders (DBD). However, it is still not fully understood how these three factors are interrelated. This study evaluated the association between childhood maltreatment and DBD testing the role of EF performance as a mediator or moderator. We studied a probabilistic school-based sample of 2016 children from 6 to 12 years. Mental disorders were assessed using the Development and Well-Being Assessment with parents and children. Children answered questions about exposure to child maltreatment and were evaluated with a set of cognitive tasks addressing inhibitory control, working memory, cognitive flexibility and planning. Childhood maltreatment was strongly associated with DBD (OR = 7.7, CI 95% 4.5-12.9). No association was found between childhood maltreatment and EF performance. Children with DBD showed worse performance in cognitive flexibility, which was not identified as a mediator or moderator of the association between childhood maltreatment and DBD. Results indicate that the association between maltreatment and disruptive behavior occurs regardless of performance in executive function in a community sample. Future studies are essential to confirm these findings and elucidate the cognitive mechanisms involved in this association.

Structural Brain Connectivity in Childhood Disruptive Behavior Problems: A Multidimensional Approach.

BACKGROUND: Studies of white matter connectivity in children with disruptive behavior have yielded inconsistent results, possibly owing to the trait's heterogeneity, which comprises diverse symptoms like physical aggression, irritability, and delinquency. This study examined associations of global and specific white matter connectivity with childhood disruptive behavior problems, while accounting for their complex multidimensionality. METHODS: In a large cross-sectional population-based study of 10-year-old preadolescents (n = 2567), we assessed four previously described empirically derived dimensions of disruptive behavior problems using the Child Behavior Checklist: physical aggression, irritability, disobedient behavior, and delinquent behavior. Global and specific white matter microstructure was assessed by diffusion tensor imaging. RESULTS: Global fractional anisotropy and mean diffusivity were not associated with broad measures of disruptive behavior, e.g., Child Behavior Checklist externalizing problems scale. Global fractional anisotropy was negatively associated with delinquent behavior (ß = -.123, pfalse discovery rate adjusted = .028) and global mean diffusivity was positively associated with delinquent behavior (ß = .205, pfalse discovery rate adjusted < 0.001), suggesting reduced white matter microstructure in preadolescents with higher levels of delinquent behavior. Lower white matter microstructure in the inferior longitudinal fasciculus, superior longitudinal fasciculus, cingulum, and uncinate underlie these associations. Global white matter microstructure was not associated with physical aggression, irritability, or disobedient behavior. CONCLUSIONS: Delinquent behavior, a severe manifestation of childhood disruptive behavior, was associated with lower white matter microstructure in tracts connecting frontal and temporal lobes. These brain regions are involved in decision making, reward processing, and emotion regulation. This study demonstrated that incorporating the multidimensional nature of childhood disruptive behavior traits shows promise in advancing the search for elucidating neurobiological correlates of disruptive behavior.

Peer-Influence on Risk-Taking in Male Adolescents with Mild to Borderline Intellectual Disabilities and/or Behavior Disorders.

This study aimed to disentangle the effects of Mild-to-Borderline Intellectual Disability (MBID) and Behavior Disorders (BD)on risk taking in circumstances where peer influence was absent or present. We studied 319 adolescents in four groups: MBID-only, MBID+BD, BD-only, and typically developing controls. The Balloon Analogue Risk-Task (BART), in a solo or peer condition, was used as a proxy of real-life risk-taking. Results show a significant main effect of BART condition. Post-hoc tests indicated higher risk-taking in the peer compared to the solo condition in all groups except BD-only. Moreover, risk taking was increased in adolescents with MBID compared to adolescents without MBID, but only under peer-influence. No main or interaction effects with BD were observed. Model based decomposition of BART performance in underlying processes showed that the MBID related increase in risk-taking under peer-influence was mainly related to increased risk-taking propensity, and in the MBID-only group also to increased safety estimates and increased confidence in these safety estimates. The present study shows that risk-taking in MBID may be better explained by low intellectual functioning than by comorbid BD, and may not originate in increased risk taking per se, but may rather be related to risk-taking under peer-influence, which is a complex, multifaceted risk-taking context. Therefore, interventions to decrease risk-taking by adolescents with MBID that specifically target peer-influence may be successful.

Emotional processing deficits in Italian children with Disruptive Behavior Disorder: The role of callous unemotional traits.

Research suggests that callous unemotional (CU) traits are associated with poor emotion recognition due to impairments in attention to relevant emotional cues. To further investigate the mechanisms that underlie CU traits, this study focused on the relationship between levels of CU and children's attention to, and recognition of, facial emotions. Participants were 7- to 10-year-old Italian boys, 35 with a diagnosis of Disruptive Behavior Disorder (age: M = 8.93, SD = 1.35), and 23 healthy male controls (age: M = 8.86, SD = 1.35). Children viewed standardized emotional faces (happiness, sadness, fear, disgust, anger, and neutral) while eye-tracking technology was used to evaluate scan paths for each area of interest (eyes, face, mouth), and for each emotion. CU traits were assessed using parent and teacher ratings on the Antisocial Process Screening Device. In the whole sample, elevated levels of CU traits were associated with a lower ability to recognize sadness, a lower number of fixations, and a lower average length of each fixation, specifically to the eye area of sad faces. In children with Disruptive Behavior Disorder diagnoses, high levels of CU traits were associated with lower duration of fixations to the eye-region on the eye area of sad faces, which in turns predicted lower levels of sadness recognition. The findings confirm that poor emotion recognition is associated with impairments in attention to critical information about other people's emotions. The clinical implications are discussed.

Dysfunctional Social Reinforcement Processing in Disruptive Behavior Disorders: An Functional Magnetic Resonance Imaging Study.

OBJECTIVE: Prior functional magnetic resonance imaging (fMRI) work has revealed that children/adolescents with disruptive behavior disorders (DBDs) show dysfunctional reward/non-reward processing of non-social reinforcements in the context of instrumental learning tasks. Neural responsiveness to social reinforcements during instrumental learning, despite the importance of this for socialization, has not yet been previously investigated. METHODS: Twenty-nine healthy children/adolescents and 19 children/adolescents with DBDs performed the fMRI social/non-social reinforcement learning task. Participants responded to random fractal image stimuli and received social and non-social rewards/non-rewards according to their accuracy. RESULTS: Children/adolescents with DBDs showed significantly reduced responses within the caudate and posterior cingulate cortex (PCC) to non-social (financial) rewards and social non-rewards (the distress of others). Connectivity analyses revealed that children/adolescents with DBDs have decreased positive functional connectivity between the ventral striatum (VST) and the ventromedial prefrontal cortex (vmPFC) seeds and the lateral frontal cortex in response to reward relative to non-reward, irrespective of its sociality. In addition, they showed decreased positive connectivity between the vmPFC seed and the amygdala in response to non-reward relative to reward. CONCLUSION: These data indicate compromised reinforcement processing of both non-social rewards and social non-rewards in children/adolescents with DBDs within core regions for instrumental learning and reinforcement-based decision- making (caudate and PCC). In addition, children/adolescents with DBDs show dysfunctional interactions between the VST, vmPFC, and lateral frontal cortex in response to rewarded instrumental actions potentially reflecting disruptions in attention to rewarded stimuli.
