CBT-Enhanced Emotion Regulation as a Mechanism of Improvement for Childhood Irritability

Associations between trauma exposure and irritability within the family unit: a network approach

BACKGROUND

Pediatric irritability is a pervasive psychiatric symptom, yet its etiology remains elusive. While trauma exposure may contribute to the development of irritability, empirical research is limited. This study examined the prevalence of irritability among trauma-exposed children, identified factors that differentiate trauma-exposed children with and without irritability, and employed a network analysis to uncover associations between irritability and trauma exposure in the family unit.

METHODS

Sample included 676 children (56.3% male, mean age = 9.67 ± 3.7 years) and their parents referred by the Connecticut Department of Children and Families to Fathers for Change - a psychotherapy intervention designed to reduce intimate partner violence (IPV) and child maltreatment. Child's trauma exposure, post-traumatic stress disorder (PTSD) symptoms, and irritability were assessed pre-intervention using self- and caregiver-report. Parents self-reported their childhood and adulthood trauma exposures, PTSD symptoms, irritability, psychopathology, and IPV.

RESULTS

Across caregiver- and child-reports, 16%-17% of children exhibited irritability. Irritable children experienced greater trauma exposure, interpersonal violence, emotional abuse, and PTSD severity. They had caregivers, particularly mothers, with greater trauma histories, IPV, and psychopathology. Network analysis revealed 10 nodes directly correlated to child's irritability including child's PTSD severity, parental IPV (specifically psychological violence), and parental psychopathology.

CONCLUSIONS

Results provide initial empirical evidence that pediatric irritability is linked to trauma exposure, suggesting trauma histories be considered in the diagnosis and treatment of irritability. Interventions addressing caregiver trauma, IPV, and psychopathology may ameliorate pediatric irritability. Future studies could benefit from adopting network approaches with longitudinal or time series data to elucidate causality and points of intervention.

Emotion regulation as central to psychopathology across childhood and adolescence: a commentary on Nobakht et al. (2023)

An important goal of clinical/developmental research is to identify factors contributing to the onset and maintenance of psychopathology - particularly factors that could be modified through intervention. Large-scale, multi-informant, longitudinal studies provide valuable opportunities for testing such etiological hypotheses, as illustrated by Nobakht et al.'s recent six-wave cohort study spanning ages 4-14. At a within-person level, emotion regulation (ER) deficits consistently predicted oppositional defiant disorder (ODD) symptoms (including both irritability and defiance), whereas victimization did not. These results comport with growing evidence highlighting ER's centrality to ODD and psychopathology more broadly. While the ER findings carry promising implications, caution is warranted in interpreting the results for victimization given that its association with psychopathology is well-documented. More research is needed to test precise questions about within- and between-person processes involving ER, victimization, and psychopathology across development. Pressing research questions include whether, how, and when youths' ER can be modified, and with what effects on clinical outcomes.

Association Between Child Maltreatment and Aggression in Chinese Early Adolescents: The Mediating Role of Irritability

Child maltreatment (CM) is a major global public health issue, and a strong association exists between CM and aggression. However, the underlying mechanism of this association has not been understood to date. The objective of this study was to explore the mediating role of irritability in the association between CM and aggression in Chinese early adolescents. A cross-sectional study was conducted using a self-report questionnaire to evaluate the levels of CM, aggression, and irritability in 5,724 middle school students from the Anhui Province, China. Structural equation modeling was used to test the hypothesis of the mediating effect of irritability on the relationship between CM and aggression. We further investigated gender differences in this association using multiple group analyses. CM was positively related to both irritability and aggression, and irritability was positively associated with aggression (p < .01). The mediating effects of irritability between CM and aggression were significant (β = .107, 95% confidence intervals [CI]: 0.077-0.133, p < .05). Males had a higher indirect effect size of the pathway from CM to aggression via irritability compared with females. Overall, irritability was a crucial mediator in the relationship between CM and aggression in Chinese adolescents, and males were more prone to engage in aggression compared with females through the pathway of irritability. Therefore, early irritability characteristics should be carefully monitored in adolescents, and they should be provided adequate support to acquire critical emotion regulation skills.

Efficacy of the Fast Track Friendship Group Program for Peer-rejected Children: A Randomized-Controlled Trial

OBJECTIVE

To evaluate the benefits of the Fast Track Friendship Group program implemented as a stand-alone school-based intervention on the social cognitions, social behavior, peer and teacher relationships of peer-rejected students.

METHOD

Over four successive years, 224 peer-rejected elementary students (57% White, 17% Black, 20% Latinx, 5% multiracial; 68% male; grades 1-4; Mage = 8.1 years old) were identified using peer sociometric nominations and randomly assigned to the intervention (n = 110) or a treatment-as-usual control group (n = 114). Four school districts serving economically-disadvantaged urban and rural communities participated. Intervention involved weekly small group social skills training with classmate partners, with sessions tailored to address individual child needs. Consultation meetings held at the start and mid-point of intervention were designed to help teachers and parents support the generalization of targeted skills.

RESULTS

Multi-level linear models, with children nested within schools (controlling for demographics and baseline scores) documented improvements in social-cognitive skills (direct assessments of emotion recognition and competent social problem-solving), social behavior (teacher ratings of social skills and externalizing behavior), and interpersonal relationships (peer sociometric nominations of peer acceptance and friendships, teacher-rated student-teacher closeness). Significant effects were generally small (ds = .19-.36) but consistent across child sex, grade level, and behavioral characteristics.

CONCLUSIONS

The intervention proved feasible for high-fidelity implementation in school settings and produced significant improvements in the social adjustment of peer-rejected children, validating the approach as a school-based Tier 2 intervention.

Trajectories of oppositional defiant disorder severity from adolescence to young adulthood and substance use, mental health, and behavioral problems

Background

Oppositional Defiant Disorder (ODD) is a disruptive behavioral disorder; however, increasing evidence emphasizes irritable mood as a primary symptom of ODD.

Objectives

This study investigated whether heterogeneous groups (classes) of individuals can be differentiated based on ODD sub-dimensions (irritability and defiance) or on overall ODD symptoms longitudinally. We also examine associations between ODD trajectory class and comorbid substance use (heavy episodic drinking, cannabis use), mental health (depression and anxiety) and behavioral symptoms (ADHD, aggression and substance use) in both adolescence and young adulthood (controlling for adolescent levels of each of these concerns).

Method

Data were from a randomly recruited community sample of 662 Canadian youth (T1 ages 12-18) followed biennially for 10 years (T6 ages 22-29).

Results

Growth mixture models revealed trajectories classes of ODD based on severity of symptoms. A three-class solution provided the best fit with Low (n = 119; 18%), Moderate (n = 473; 71.5%), and High (n = 70; 10.6%) ODD classes. Class trajectory differences were similarity based on symptoms severity (rather than type) for symptom sub-dimensions (irritability defiance). Adolescent and young adult substance use, mental health symptoms, and behavioral problems were significantly higher for the High ODD trajectory class compared to both other classes. Youth in the Moderate ODD trajectory class also showed higher comorbid symptoms in adolescence and young adulthood, compared to the Low ODD trajectory class.

Conclusion

Early identification of children and adolescents with high or moderate ODD symptoms and interventions that simultaneously address defiance and irritability are supported by the findings.

Future Directions in Youth Irritability Research

Research on irritability in children and adolescents has proliferated over the last 20 years. The evidence shows the clinical and developmental significance of irritable mood and behavior in youth, and it has led to significant changes in mental health classification, diagnosis, and services. At the same time, this research (including our own) has led to relatively little new in terms of practical, empirically based guidance to improve interventions and outcomes. In this article, we briefly summarize some of these developments and current evidence-based practices. We then put forth two key substantive challenges (the "whats") for future research to address: (a) the need for more effective treatments, especially evaluating and adapting evidence-based treatments that are already well-established for problems related to irritability (e.g., cognitive-behavioral therapies for internalizing and externalizing problems); and (b) the need for a better mechanistic understanding of irritability's phenomenology (e.g., phasic vs. tonic irritability, how frustration unfolds) and putative underlying mechanisms (e.g., cognitive control, threat and reward dysfunction). Lastly, we suggest three methodological approaches (the "hows") that may expedite progress in such areas: (a) ecological momentary assessment, (b) digital health applications, and (c) leveraging existing datasets. We hope this article will be useful for students and early-career researchers interested in tackling some of these important questions to better meet the needs of severely irritable youth.

Parent Accommodation Contemporaneously Mediates the Association Between Youth Irritability and Youth Anxiety Treatment Outcome

Research documents that child and adolescent (youth) irritability and anxiety have high co-occurrence, and anxious-irritable presentations are associated with greater impairment than anxious nonirritable presentations. This study examines the association between irritability and youth anxiety treatment outcome and tests a conceptual model of the associations among youth irritability, parent accommodation, and youth anxiety severity following cognitive behavioral treatment (CBT). Participants were N = 128 clinic-referred youths ages 6 to 17 years (M = 9.76 years; 57% female) who met criteria for primary anxiety disorder diagnoses and completed a 12- to 14-week CBT anxiety protocol. Parent- and youth-report on youth irritability, parent accommodation of their child's anxiety, and youth anxiety severity were assessed pretreatment and posttreatment. Using parent-report, youth irritability at pretreatment was associated with high parent accommodation of youth anxiety and high youth anxiety severity at posttreatment. The association between irritability and youth anxiety outcome was mediated contemporaneously by parent accommodation at posttreatment. These findings show that parent accommodation of their anxious-irritable children's anxiety may account for high youth anxiety severity following treatment. Developing strategies to target irritability in anxious youth and/or reduce parent accommodation in the presence of youth irritability represent important directions for future research.

Regulating Together: Emotion Dysregulation Group Treatment for ASD Youth and Their Caregivers

Individuals with autism spectrum disorder (ASD) experience behavioral and emotional symptoms hypothesized to arise from emotion dysregulation (ED), difficulty modulating emotional experience, expression, and intensity in an acceptable and contextually appropriate manner. We developed Regulating Together (RT)-an intensive-outpatient, caregiver-assisted group program to meet the ASD + ED intervention critical need. A within-subjects trial was conducted (5-week-control lead-in period, 5-week-treatment, and 5-and 10-weeks-post-treatment follow-ups). Forty-four youth with ASD + ED (25 8-12, 19 13-18 yr-olds, 88% male, mean FSIQ of 96) participated. Improvements were found in reactivity, emotion regulation knowledge, and flexibility post-treatment and 10-weeks post-treatment. A reduction in inpatient hospitalization rates by 16% from the 12 months pre-RT to 12 months post-RT was observed. RT shows promise to reduce ED in ASD.

Inter-relationships of depressive and anxiety symptoms with suicidality among adolescents: A network perspective

BACKGROUND

Persons with suicidality including suicidal ideation (SI), suicide plans (SP) and/or suicide attempts (SA) are at higher risk for future suicide than those without suicidality. To reduce the risk of future suicide, it is important to understand symptoms of emotional distress that have the strongest links with SI, SP and SA. This network analysis examined item-level relations of depressive and anxiety symptoms with suicidality among adolescents during the COVID-19 pandemic.

METHODS

Adolescents between 12 and 20 years of age were assessed with the Patient Health Questionnaire (PHQ-9), Generalized Anxiety Disorder Scale (GAD-7), and individual binary reponse (no/yes) items assessing SI, SP, and SA during the pandemic. The structure of depressive symptoms, anxiety symptoms and suicidality was characterized using "Expected Influence" and "Bridge Expected Influence" as centrality indices in the symptom network. Network stability was tested using a case-dropping bootstrap procedure. Node-specific predictive betweenness was computed to examine short paths of anhedonia, other depressive symptoms and anxiety symptoms with suicidality. A Network Comparison Test (NCT) was conducted to examine whether network characteristics differed based on gender.

RESULTS

Prevalence rates of depressive symptoms, anxiety symptoms, and suicidality were 44.60 % (95% confidence interval (CI) = 41.53-47.67 %), 31.12 % (95%CI = 28.26-33.98 %), and 16.95 % (95%CI = 14.63-19.26 %), respectively, in the study sample. The network analysis identified GAD3 ("Worry too much") as the most central symptom, followed by GAD6 ("Irritability") and PHQ6 ("Guilt") in the sample. Additionally, PHQ6 ("Guilt"), GAD6 ("Irritability"), and PHQ2 ("Sad mood") were bridge nodes linking depressive and anxiety symptoms with suicidality. A flow network indicated that the connection between S ("Suicidality") and PHQ6 ("Guilt") reflected the strongest connection, followed by connections of S ("Suicidality") with GAD2 ("Uncontrollable worrying"), and S ("Suicidality") with PHQ2 ("Sad mood"). Finally, PHQ2 ("Sad mood") was the main bridge node linking anhedonia with other depressive and anxiety symptoms and suicidality in the sample.

CONCLUSIONS

Findings highlight the potential importance of reducing specific depressive and anxiety symptoms as possible means of reducing suicidality among adolescents during the pandemic. Central symptoms and key bridge symptoms identified in this study should be targeted in suicide prevention for at-risk adolescents.

The Role of Emotion Regulation and Executive Functioning in the Intervention Outcome of Children with Emotional and Behavioural Problems

Emotional and behavioural problems are closely associated with impairments in regulating emotions and in executive functions (EF). To examine this further, the aim of the present study was to determine whether EF and emotion regulation at baseline would predict emotional and behavioural problem scores post-intervention, and further explore the extent to which emotion regulation mediates these outcomes. Participants were 41 primary school children who exhibited emotional and/or behavioural problems, aged 8 to 11 years. All the children completed measures of emotional and behavioural problems, cognitive emotion regulation, anxiety symptoms, and performed two experimental tasks to measure working memory and response inhibition before and after participating in a transdiagnostic Cognitive Behaviour Therapy-based programme, "Super Skills for Life" (SSL), and at 3-months follow-up. Results revealed significant reduction in the use of maladaptive emotion regulation strategy catastrophising and other blame following the intervention. Additionally, EF and emotion regulation was associated with outcomes for emotional problems and conduct problems. More specifically maladaptive emotion regulation strategy such as catastrophising and other blame was closely related with self-reports of emotional problems, likewise other blame, was also linked with scores of conduct problems. This study provides preliminary empirical support for EF and emotion regulation in predicting outcomes of emotional and behavioural problems in children following intervention.

Eight-year trajectories of behavior problems and resilience in children exposed to early-life intimate partner violence: The overlapping and distinct effects of individual factors, maternal characteristics, and early intervention

Childhood exposure to intimate partner violence (IPV) can have lasting effects on well-being. Children also display resilience following IPV exposure. Yet, little research has prospectively followed changes in both maladaptive and adaptive outcomes in children who experience IPV in early life. The goal of the current study was to investigate how child factors (irritability), trauma history (severity of IPV exposure), maternal factors (mental health, parenting), and early intervention relate to trajectories of behavior problems (internalizing and externalizing problems) and resilience (prosocial behavior, emotion regulation), over 8 years. One hundred twenty mother-child dyads participated in a community-based randomized controlled trial of an intervention for IPV-exposed children and their mothers. Families completed follow-up assessments 6-8 months (N = 71) and 6-8 years (N = 68) later. Although intention-to-treat analyses did not reveal significant intervention effects, per-protocol analyses suggested that participants receiving an effective dose (eight sessions) of the treatment had fewer internalizing problems over time. Child irritability and maternal parenting were associated with both behavior problems and resilience. Maternal mental health was uniquely associated with child behavior problems, whereas maternal positive parenting was uniquely associated with child resilience. Results support the need for a dyadic perspective on child adjustment following IPV exposure.

Effectiveness of Child-Focused Interventions for Externalizing Behavior: a Rapid Evidence Review

Parent behavior management training (BMT) is well established as an effective, evidence-based treatment for children with externalizing behavior. Despite the wealth of data supporting BMT, many community providers use a variety of child-focused and non-directive interventions to target behavior problems. There is lack of clarity as to whether the evidence supporting child-focused externalizing treatments is sufficiently compelling to support offering these treatments rather than or in addition to BMT. This rapid evidence review compares the effectiveness of BMT with several common child-focused interventions for externalizing behavior including cognitive behavioral (CBT), social skill (SS), and play/dynamic (PT) approaches. PubMed, PsychINFO, and Web of Science were searched for English-language articles from year 2000 onwards for each intervention type. Inclusion criteria were child age (12 and under), presence of a child-focused behavioral treatment condition, and externalizing behavior as an outcome variable. A total of 30 studies met inclusion criteria and were coded (13 CBT, 10 SS, 7 PT). Results supported social skills interventions with accompanying BMT as effective in improving externalizing problems, with generally moderate effect sizes. Individual social skills interventions were promising but needing further evaluation compared to treatment as usual. CBT treatments with and without accompanying BMT showed moderate effects over waitlist but produced less consistently significant effects compared to more robust controls. Play therapy approaches showed inconsistent effects and require further evaluation. This review supports social skills plus BMT treatments as a child-focused intervention with probable efficacy for child externalizing problems. Implications for policy and community practice are discussed.

Efficacy of cognitive behavioral therapy on aggressive behavior in children with attention deficit hyperactivity disorder and emotion dysregulation: study protocol of a randomized controlled trial

BACKGROUND

Attention deficit hyperactivity disorder (ADHD) is frequently associated with emotional dysregulation (ED). ED is characterized by excessive and inappropriate emotional reactions compared to social norms, uncontrolled and rapid shifts in emotion, and attention focused on emotional stimuli. Few studies have evaluated non-pharmacological interventions to improve ED in children with ADHD. The current randomized controlled trial assesses the efficacy of a cognitive behavioral therapy (CBT) intervention compared with a theater-based intervention (TBI) in children with ADHD and ED.

METHODS

Sixty-eight 7- to 13-year-old children with ADHD and ED will be recruited and randomly assigned to the CBT or TBI group. CBT aims to reduce ED by teaching anger management strategies. TBI seeks to reduce ED by improving emotion understanding and expression through mimics and movement. In both groups, children participate in 15 1-h sessions, and parents participate in 8 sessions of a parent management program. The primary outcome measure is the change in the "Aggression" sub-score of the Child Behavior Checklist (CBCL). Secondary outcome measures include overall impairment (Children's Global Assessment Scale, Strengths and Difficulties Questionnaire), personality profile (Hierarchical Personality Inventory for Children), executive function (Behavioral Rating Inventory of Executive Function), quality of life (Kidscreen-27), parental stress (Parenting Stress Index, 4th edition), parental depression (Beck Depression Inventory-II), and impact of child disorders on the quality of the family life (Parental Quality of Life and Developmental Disorder).

DISCUSSION

Children with ADHD and ED are at risk of functional impairment and poor outcomes and have specific therapeutic needs. This randomized controlled trial wants to assess non-pharmacological treatment options for this population.

Parent Management Training Combined with Group-CBT Compared to Parent Management Training Only for Oppositional Defiant Disorder Symptoms: 2-Year Follow-Up of a Randomized Controlled Trial

Parent management training (PMT) is recommended treatment for children with oppositional defiant disorder (ODD) and child-directed cognitive behavior therapy (CBT) is also recommended for school-aged children. The current study examined 2-year follow-up effects of parent management training (PMT) combined with the CBT based group intervention Coping Power Program (CPP) compared to PMT only. Results showed long-term effectiveness of both PMT and PMT combined with CPP in reduced disruptive behavior problems and harsh parenting strategies, and increased emotion regulation- and social communication skills. The earlier reported increase in emotion regulation- and social communication skills in the PMT with CPP condition during treatment remained stable while the PMT condition showed continued improvement during the follow-up period. To conclude, PMT with CPP did generally not provide significant benefits at the 2-year follow-up compared to PMT, apart from an improvement earlier in time regarding emotion regulation- and social communication skills.Trial registration number ISRCTN10834473, date of registration: 23/12/2015.

A Review of the Evidence Base for Psychosocial Interventions for the Treatment of Emotion Dysregulation in Children and Adolescents

Many children with a range of psychiatric diagnoses manifest impaired levels of emotion dysregulation (ED). Over the past decade, there has been increasing examination of psychosocial interventions for ED. We found preliminary evidence of positive effects for a wide range of psychosocial treatments that were associated with improvements in emotion recognition, emotional reactivity, and emotion regulation. More studies are needed because results are limited by the small number of controlled trials, heavy reliance on parent ratings, and heterogeneity of the samples.

Emotion regulation training as a treatment element for externalizing problems in adolescence: A randomized controlled micro-trial

Improving interventions for externalizing problems in adolescence may require determining which treatment elements actually produce change. In this micro-trial, we tested a treatment element addressing one widely-hypothesized mechanism underlying externalizing problems: emotion regulation. We tested whether emotion regulation could be improved via training, whether adolescents who received such training would subsequently show reduced externalizing problems, and which training approach and sequence was most effective. We randomized 108 adolescents with elevated externalizing problems (71.3% boys, M_age = 13.66, SD = 1.10) to a control condition or an experimental condition teaching emotion regulation through either a cognitive or behavioral approach, in alternated sequences. Effects of the modules were assessed before and after the modules, and with weekly assessments. The results showed a positive effect of the experimental training on self-reported use of adaptive emotion regulation strategies. However, self-reported externalizing problems decreased more in the control condition than in the experimental condition. No mediation, approach (cognitive versus behavioral) or sequence (cognitive-behavioral versus behavioral-cognitive sequence) effects were found. These findings illustrate that change in a proposed mechanism may not be accompanied by change in targeted problems; this highlights the importance of testing the hypothesized impact of specific treatment elements on targeted mental health problems. TRIAL REGISTRATION: This trial was registered in the Dutch Trial Register (NTR7334, July 10th, 2018) and the study protocol was published (te Brinke, Schuiringa, Menting, Deković, & de Castro, 2018).

Feasibility and acceptability of a brief cognitive-behavioral group intervention for chronic irritability in youth

Chronic irritability is a core feature of oppositional defiant disorder (ODD) and disruptive mood dysregulation disorder (DMDD), but few irritability-specific interventions have been tested. Existing evidence-based treatments for disruptive behavior problems offer a strong template. This pilot study was conducted to develop and evaluate a brief irritability-specific module of a validated cognitive-behavioral group intervention for children (Stop Now And Plan (SNAP) Program). Stop now and plan for irritability (I-SNAP) retained core elements of SNAP in a shortened 6-week format. Community families with irritable children (M = 8.44 years, SD = 1.42) were recruited for parent and child emotion regulation skills groups. Of 18 children enrolled (72% male), 14 completed (78%). Half of children attended all six sessions, though homework compliance was lower. All parents reported favorable impressions and would recommend I-SNAP to others. Significant improvements were seen from pre- to post-treatment across parent-reported irritability, ODD symptoms, emotion regulation, and disciplinary effectiveness. This pilot study provides initial support suggesting I-SNAP may be feasible to implement and acceptable to parents. In addition, pilot analyses demonstrated that this brief group intervention was associated with positive outcomes consistent with treatment targets. This preliminary evidence supports the need for further research to assess I-SNAP's effects on irritability relative to control groups.

Conflict Resolution and Emotional Expression in Mother-Preadolescent Dyads: Longitudinal Associations with Children's Socioemotional Development

How youth learn to manage emotions during mother-child conflict influences their socioemotional development. Ninety-four mother-preadolescent (aged 9-13, 57.4% female) dyads were observed during conflict discussions and completed questionnaire measures at one prior time-point (Time 1; ages 6-10) and one subsequent time-point (Time 3; ages 11-16) to the observations (Time 2). The temporal associations between individuals' emotional expressions and their own and their partners' verbal conflict behaviors were observed. Mothers and preadolescents were more attacking and assertive when angry, and more conciliatory and avoidant when sad. Neutral affect predicted the most constructive behaviors, while positive affect promoted avoidance. The responses were similar following their partners' emotions. Maternal conflict-escalating responses to anger were associated with difficult characteristics in earlier childhood and socioemotional difficulties in adolescence. Maternal and child de-escalation following sadness predicted socioemotional adjustment in adolescence. These results demonstrate that conflict resolution between preadolescents and their mothers is influenced by the emotional climate of the interaction, and that the management of negative emotions within the dyad is tied to youth's socioemotional development.

Efficacy of psychosocial interventions for children with ADHD and emotion dysregulation: a systematic review

Attention-Deficit Hyperactivity Disorder (ADHD) is frequently associated with emotion dysregulation (ED) that is characterized by excessive and inappropriate emotional reactions. Children with ADHD and ED present significant social, academic and family functioning impairments. These findings indicate that ED should be regularly monitored in children with ADHD and should be managed with targeted therapeutic interventions. However, few studies have evaluated the efficacy of psychosocial interventions to manage ED in children with ADHD. The aim of this systematic review was to assess the effects of psychosocial interventions for children with ADHD and ED, particularly their benefits and limitations. This review followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) model. A systematic literature search of different databases in February 2018 allowed the identification of five randomized controlled trials, one quasi-experimental study, and four open-label uncontrolled studies. Analysis of the results reported in these studies suggested that psychosocial interventions can improve severe irritability and aggressive behavior in children with ADHD and ED. However, the short trial duration, the lack of follow-up and of control group in several studies, and the heterogeneity of the outcome measures affected the result interpretation. Future studies should use standardized measures of ED and larger samples.

Outcomes of Randomized Clinical Trials of Interventions to Enhance Social, Emotional, and Spiritual Components of Wisdom: A Systematic Review and Meta-analysis

Importance

Wisdom is a neurobiological personality trait made up of specific components, including prosocial behaviors, emotional regulation, and spirituality. It is associated with greater well-being and happiness.

Objective

To evaluate the effectiveness of interventions to enhance individual components of wisdom.

Data Sources

MEDLINE and PsycINFO databases were searched for articles published through December 31, 2018.

Study Eligibility Criteria

Randomized clinical trials that sought to enhance a component of wisdom, used published measures to assess that component, were published in English, had a minimum sample size of 40 participants, and presented data that enabled computation of effect sizes were included in this meta-analysis.

Data Extraction and Synthesis

Random-effect models were used to calculate pooled standardized mean differences (SMDs) for each wisdom component and random-effects meta-regression to assess heterogeneity of studies.

Main Outcomes and Measures

Improvement in wisdom component using published measures.

Results

Fifty-seven studies (N = 7096 participants) met review criteria: 29 for prosocial behaviors, 13 for emotional regulation, and 15 for spirituality. Study samples included people with psychiatric or physical illnesses and from the community. Of the studies, 27 (47%) reported significant improvement with medium to large effect sizes. Meta-analysis revealed significant pooled SMDs for prosocial behaviors (23 studies; pooled SMD, 0.43 [95% CI, 0.22-0.3]; P = .02), emotional regulation (12 studies; pooled SMD, 0.67 [95% CI, 0.21-1.12]; P = .004), and spirituality (12 studies; pooled SMD, 1.00 [95% CI, 0.41-1.60]; P = .001). Heterogeneity of studies was considerable for all wisdom components. Publication bias was present for prosocial behavior and emotional regulation studies; after adjusting for it, the pooled SMD for prosocial behavior remained significant (SMD, 0.4 [95% CI, 0.16-0.78]; P = .003). Meta-regression analysis found that effect sizes did not vary by wisdom component, although for trials on prosocial behaviors, large effect sizes were associated with older mean participant age (β, 0.08 [SE, 0.04]), and the reverse was true for spirituality trials (β, -0.13 [SE, 0.04]). For spirituality interventions, higher-quality trials had larger effect sizes (β, 4.17 [SE, 1.07]), although the reverse was true for prosocial behavior trials (β, -0.91 [SE 0.44]).

Conclusions and Relevance

Interventions to enhance spirituality, emotional regulation, and prosocial behaviors are effective in a proportion of people with mental or physical illnesses and from the community. The modern behavioral epidemics of loneliness, suicide, and opioid abuse point to a growing need for wisdom-enhancing interventions to promote individual and societal well-being.

Exploring Longitudinal Mechanisms of Irritability in Children: Implications for Cognitive-Behavioral Intervention

Severe irritability is a common and clinically important problem longitudinally associated with internalizing and externalizing problems in children. To better understand these mechanisms and to inform treatment research, we tested cognitive-behavioral processes as candidate mediators in the paths from irritability to later problems. Methods: A school sample (N = 238, 48% female, ages 8-10) was assessed at ~6-month intervals in fall (T1) and spring (T2) of third to fourth grade, and again the following fall (T3). Measures assessed irritability (T1/predictor); anger and sadness coping, intolerance of uncertainty, and rumination; (T1-T2/mediators); and anxiety, depressive symptoms, reactive aggression, and oppositionality (T1-T3/outcomes). Focused cross-lagged panel models, controlling for gender and grade, were specified to examine full (X_T1 ➔ M_T2 ➔ Y_T3) and half (X_T1 ➔ M_T2; M_T1 ➔ Y_T2) longitudinal mediation. Across one or more intervals, irritability predicted higher depressive symptoms, anxiety, reactive aggression, oppositionality, intolerance of uncertainty, and poor emotion coping. From T1 irritability to T2/T3 outcomes, mediation was found for poor sadness coping leading to reactive aggression and oppositionality; poor anger coping to anxiety, depressive symptoms, and oppositionality; and intolerance of uncertainty to anxiety. Results offer further evidence for internalizing and externalizing outcomes of youth irritability and new evidence suggesting underlying mechanisms. Irritability may confer risk for externalizing problems via poor sadness/anger coping, and for internalizing problems via poor anger coping and intolerance of uncertainty. Theoretical models and psychosocial treatment should consider addressing regulation of various unpleasant emotions as well as psychological flexibility and tolerating uncertainty.

Statistical power in partially nested designs probing multilevel mediation

Objective: Analysis of the intermediate behaviors and mechanisms through which innovative therapies come to shape outcomes is a critical objective in many areas of psychotherapy research because it supports the iterative exploration, development and refinement of theories and therapies. Despite widespread interest in the intermediate behaviors and mechanisms that convey treatment effects, there is limited guidance on how to effectively and efficiently design studies to detect such mediated effects in the types of partially nested designs that commonly arise in psychotherapy research. In this study, we develop statistical power formulas to identify requisite sample sizes and guide the planning of studies probing mediation under two- and three-level partially nested designs. Method: We investigate multilevel mediation in partially nested structures and models for two- and three-level designs. Results: Well-powered studies probing mediation using partially nested designs will typically require moderate to large sample sizes or moderate to large effects. Discussion: We implement these formulas in the R package PowerUpR and a simple Shiny web application (https://poweruprshiny.shinyapps.io/PartiallyNestedMediationPower/) and demonstrate their use to plan studies using partially nested designs.

Dysregulated Irritability as a Window on Young Children's Psychiatric Risk: Transdiagnostic Effects via the Family Check-Up

Building on prior work using Tom Dishion's Family Check-Up, the current article examined intervention effects on dysregulated irritability in early childhood. Dysregulated irritability, defined as reactive and intense response to frustration, and prolonged angry mood, is an ideal marker of neurodevelopmental vulnerability to later psychopathology because it is a transdiagnostic indicator of decrements in self-regulation that are measurable in the first years of life that have lifelong implications for health and disease. This study is perhaps the first randomized trial to examine the direct effects of an evidence- and family-based intervention, the Family Check-Up (FCU), on irritability in early childhood and the effects of reductions in irritability on later risk of child internalizing and externalizing symptomatology. Data from the geographically and sociodemographically diverse multisite Early Steps randomized prevention trial were used. Path modeling revealed intervention effects on irritability at age 4, which predicted lower externalizing and internalizing symptoms at age 10.5. Results indicate that family-based programs initiated in early childhood can reduce early childhood irritability and later risk for psychopathology. This holds promise for earlier identification and prevention approaches that target transdiagnostic pathways. Implications for future basic and prevention research are discussed.
