The Role of Perspective Taking and Self-Control in a Preventive Intervention Targeting Childhood Disruptive Behavior.

Prevention studies typically focus on outcome variables such as reductions in problem behavior, rather than targeted factors (e.g., cognitions), or the relation between change in targeted factors and outcomes. Therefore, the current study examined the effect of a targeted prevention program for childhood disruptive behavior on targeted factors (i.e., perspective taking and self-control) and associations between change in targeted factors and outcomes (i.e., aspects of disruptive behavior). The sample consisted of 173 children (Mage = 10.2 years) who were randomly assigned to an intervention condition (n = 70) or waitlist control condition (n = 103). Assessment took place at pre-, post- and follow-up measurements. For ethical considerations, follow-up data was not available for children on the waitlist. Findings revealed a direct intervention effect on self-control. From pre-test to follow-up, children who received the intervention improved in perspective taking and self-control. Moreover, improvements in self-control were associated with and predicted reductions in teacher-reported symptoms of oppositional defiant disorder. No associations were found between changes in perspective taking and disruptive behavior. These findings suggest that self-control may be an important target factor in reducing childhood disruptive behavior in targeted prevention.

Disruptive Behavior Disorders: The Challenge of Delineating Mechanisms in the Face of Heterogeneity.

Causal pathways to disruptive behavior disorders, even within the same diagnostic category, are varied. Both equifinality and multifinality pose considerable challenges to uncovering underlying mechanisms and understanding varied developmental trajectories associated with disruptive behavior disorders. Uncovering genetic causes requires improved granularity in how we operationalize presentation and developmental trajectories associated with disruptive behavior disorders. If we want to integrate the study of genetic, environmental, and neurocognitive factors within a longitudinal framework, we need to improve measurement. Furthermore, brain changes associated with disruptive behavior disorders should not simply be understood as outcomes of genetic and environmental influences, but also as factors that reciprocally influence future social environments over time in ways that are important in contributing to risk and resilience. Advancing the field with regard to these challenges will result in more truly integrated investigation of disruptive behavior disorders, which holds the promise of improving our ability to develop more effective preventive and intervention approaches.

[The prevention of externalizing disturbances]. / Prävention externaler Störungen ­ zum Stand der Forschung.

The prevention of externalizing disturbances Abstract. Objectives: Externalizing disturbances (attention deficit-hyperactivity disorders, oppositional defiant disorders, conduct disorders) in children and adolescents have a high prevalence, are stable over time, and precipitate a high individual and economic burden. Method: This review article presents the state of research based on selected current meta-analyzes and systematic reviews. Additionally, evidenced-based German-language prevention programs are discussed. Results: As in treatment, a multimodal approach to prevention is recommended which aims at reducing externalizing symptoms in specific settings. Interventions that focus on the specific environment in the family and the (pre-)school are preferable. Child-focused interventions are especially important in the context of peer-related problematic behavior because parent-based or teacher-based interventions may be less able to affect peer interactions. Conclusions: Comprehensive parent-based and (pre-)school-based preventive interventions of externalizing disturbances should be implemented. These should also include child-based approaches and additional parent-based group interventions. The effects of these interventions should be tested in large-scale studies.

Affective dysregulation in childhood - optimizing prevention and treatment: protocol of three randomized controlled trials in the ADOPT study.

BACKGROUND: The terms affective dysregulation (AD) and irritability describe transdiagnostic dimensions and are characterized by an excessive reactivity to negative emotional stimuli with an affective (anger) and a behavioral component (aggression). Due to early onset, high prevalence and persistence, as well as developmental comorbidity, AD in childhood is one of the most psychosocially impairing and cost-intensive mental health conditions. AD is especially prevalent in children in the youth welfare service. Despite continuous research, there remains a substantial need for diagnostic approaches and optimization of individualized treatment strategies in order to improve outcomes and reduce the subjective and economic burden. METHODS: The ADOPT (Affective Dysregulation - Optimizing Prevention and Treatment) Consortium integrates internationally established, highly experienced and interdisciplinary research groups. The work program encompasses (a) epidemiology, including prevalence of symptoms and disorders, (b) development and evaluation of screening and assessment tools, (c) stepped care approaches for clinically useful personalized medicine, (d) evaluation of an easily accessible and cost-effective online intervention as indicated prevention (treatment effects, moderation/mediation analysis), and (e) evaluation of an intensive personalized modular outpatient treatment in a cohort of children with AD who live with their parents and in a cohort of children with AD who live in out-of-home care (treatment effects, moderation/mediation analysis). DISCUSSION: The results will lead to significant recommendations for improving treatment within routine clinical care in two cohorts of children with AD and coexisting conditions, especially oppositional-defiant disorder, conduct disorder and disruptive mood dysregulation disorder.

Fifty years of preventing and treating childhood behaviour disorders: a systematic review to inform policy and practice.

QUESTION: Oppositional defiant and conduct disorders (ODD and CD) start early and persist, incurring high individual and collective costs. To inform policy and practice, we therefore asked: What is the best available research evidence on preventing and treating these disorders? STUDY SELECTION AND ANALYSIS: We sought randomised controlled trials (RCTs) evaluating interventions addressing the prevention or treatment of behaviour problems in individuals aged 18 years or younger. Our criteria were tailored to identify higher-quality RCTs that were also relevant to policy and practice. We searched the CINAHL, ERIC, MEDLINE, PsycINFO and Web of Science databases, updating our initial searches in May 2017. Thirty-seven RCTs met inclusion criteria-evaluating 15 prevention programmes, 8 psychosocial treatments and 5 medications. We then conducted narrative synthesis. FINDINGS: For prevention, 3 notable programmes reduced behavioural diagnoses: Classroom-Centered Intervention; Good Behavior Game; and Fast Track. Five other programmes reduced serious behaviour symptoms such as criminal activity. Prevention benefits were long term, up to 35 years. For psychosocial treatment, Incredible Years reduced behavioural diagnoses. Three other interventions reduced criminal activity. Psychosocial treatment benefits lasted from 1 to 8 years. While 4 medications reduced post-test symptoms, all caused important adverse events. CONCLUSIONS: Considerable RCT evidence favours prevention. CLINICAL IMPLICATIONS: Effective prevention programmes should therefore be made widely available. Effective psychosocial treatments should also be provided for all children with ODD/CD. But medications should be a last resort given associated adverse events and given only short-term evidence of benefits. Policymakers and practitioners can help children and populations by acting on these findings.

Cyberbullying in youth: A pattern of disruptive behavior / El ciberacoso en la juventud: Un patrón de comportamiento disruptivo

Despite the growing diffusion of cyberbullying among students and the numerous studies in the literature, to date relatively little is known about its relationship with school bullying. This article seeks to understand if there is an overlap between the roles of bullies and victims in traditional and electronic bullying. In order to investigate this, 5,058 Italian middle and high school students were surveyed about their experiences of cyberbullying and cybervictimisation, looking also at their involvement in school bullying. The results highlighted a significant overlap between school bullying and cyberbullying, with 12.1% of all students who bullied others at least sometimes being also cyberbullies. Similarly, there was a significant overlap between school victimisation and cybervictimisation, with 7.4% of all students who were victimised at school at least sometimes being also cybervictimised. Our findings confirm the existence of an overlap between school bullying and cyberbullying. We discuss useful intervention programs to reduce or prevent cyberbullying

A pesar de que aumenta la extensión del ciberacoso en estudiantes y de los muchos estudios al respecto, se sabe relativamente poco hasta el momento acerca de su relación con el acoso escolar. El artículo trata de entender si hay solapamiento entre los roles de agresor y víctima en el acoso tradicional y electrónico. Con el objeto de investigarlo se encuestó a 5,058 estudiantes italianos de secundaria y bachillerato sobre su experiencia de ciberacoso y cibervictimización, analizando igualmente la implicación en el acoso escolar. Los resultados ponen de manifiesto un solapamiento importante entre el acoso escolar y el ciberacoso: un 12.1% de todos los estudiantes que habían acosado a los demás al menos algunas veces habían sido también ciberacosadores. También había un solapamiento importante entre la victimización escolar y la cibervictimización: 7.4% de los estudiantes victimizados en la escuela al menos algunas veces habían sido también cibervictimizados. Los resultados confirman la existencia de solapamiento entre acoso escolar y ciberacoso. Se comentan programas de intervención útiles para disminuir o evitar el ciberacoso

Effectiveness of the Prevention Program for Externalizing Problem Behavior (PEP) in Preschoolers with Severe and No or Mild ADHD Symptoms.

Objective: The prevention program for externalizing problem behavior (PEP), developed for parents and teachers of preschool children, showed the effectiveness of both modules (PEP-PA and PEP-TE) under routine care conditions in two separate studies. This secondary analysis examined the effects of both modules on preschool children with severe attention deficit/hyperactivity disorder (ADHD) symptoms compared with children with no or mild ADHD symptoms. Methods: In the within-subject control group, design changes in child symptoms and problem behavior in specific situations at home and school during the waiting period were compared with changes during the intervention period (3 months each). Results: For children with severe ADHD, parent training reduced specific problem situations at home (HSQ-D[please provide full name here]), and teacher training showed significant effects on oppositional-aggressive behavior as well as the total problem score of the Caregiver Teacher Report Form (C-TRF). Children with no or mild ADHD benefited from parent training on the HSQ-D score, oppositional-aggressive behavior and the total problem score of the Child Behavior Checklist (CBCL), while teacher training had significant effects on all outcomes assessed. Conclusion: Our results suggest that parent training reduces mainly specific behavior problems at home in children with severe ADHD symptoms and with no/mild ADHD symptoms, while teacher training reduces ADHD symptoms and ODD[please provide full name here] symptoms including specific behavior problems in the kindergarten in children with no/mild ADHD symptoms. However, in children with severe ADHD only overall problems and ODD symptoms were significantly reduced by teacher Training.

Teachers´perception of disruptive behaviour in the classsrooms / Percepción de los docentes sobre las conductas disruptivas en las aulas de Educación Primaria

BACKGROUND: Disruptive behaviour is becoming more frequent in the classroom and is specifically associated with behaviours that hinder and obstruct the teaching-learning process. The main purpose of this paper was to investigate teachers' perceptions of this question. More specifically, we sought to observe how teachers rate the measures proposed to improve teaching, to find out which forms of schooling are preferred so as to address disruption, to identify its causes and to analyse whether there are differences arising from teacher characteristics. METHOD: 346 participants completed a disruptive-behaviour Likert-scale. The average age is 43.47, 82.9% female and 13.6% male. RESULTS: All measures are widely accepted, but there are differences in the priority given, the ideal forms of schooling is ordinary centres, although differences still exist depending on teacher characteristics; all the causes of increased problems are highly rated, with the absence of rules and limits in the family standing out. CONCLUSIONS: Teachers are calling for improvements and institutional support. Any forethought on how to improve the quality of the education system should take into account the results of this study

ANTECEDENTES: el fenómeno de la disrupción es cada vez más habitual en las aulas y se asocia específicamente a conductas que dificultan y obstaculizan el proceso de enseñanza-aprendizaje. El objetivo principal de esta investigación consiste en analizar la percepción del profesorado sobre esta cuestión. Específicamente se trata de observar qué valoración dan a las medidas propuestas para mejorar la docencia, examinar qué modalidades de escolarización consideran más idóneas para afrontar la disrupción, determinar sus causas y analizar si existen diferencias según las características del profesorado. MÉTODO: 346 participantes respondieron a una escala de conductas disruptivas tipo Likert. La edad media es de 43,47, siendo el 82,9% mujeres y el 13,6% hombres. RESULTADOS: las medidas propuestas para la mejora de la docencia son ampliamente aceptadas, existiendo diferencias en su priorización; la modalidad de escolarización idónea es la de centros ordinarios, existiendo diferencias de opinión, según las características del profesorado; y todas las causas del incremento de problemas son altamente puntuadas, destacando la falta de normas y límites en el entorno familiar. CONCLUSIONES: los profesores demandan mejoras y necesidad de apoyo institucional. Toda reflexión previa sobre cómo mejorar la calidad del sistema educativo podría tener en consideración los resultados de este estudio

Common Questions About Oppositional Defiant Disorder.

Oppositional defiant disorder (ODD) is a disruptive behavior disorder characterized by a pattern of angry or irritable mood, argumentative or defiant behavior, or vindictiveness lasting for at least six months. Children and adolescents with ODD may have trouble controlling their temper and are often disobedient and defiant toward others. There are no tools specifically designed for diagnosing ODD, but multiple questionnaires can aid in diagnosis while assessing for other psychiatric conditions. ODD is often comorbid with attention-deficit/hyperactivity disorder, conduct disorder, and mood disorders, including anxiety and depression. Behavioral therapy for the child and family members improves symptoms of ODD. Medications are not recommended as first-line treatment for ODD; however, treatment of comorbid mental health conditions with medications often improves ODD symptoms. Adults and adolescents with a history of ODD have a greater than 90% chance of being diagnosed with another mental illness in their lifetime. They are at high risk of developing social and emotional problems as adults, including suicide and substance use disorders. Early intervention seeks to prevent the development of conduct disorder, substance abuse, and delinquency that can cause lifelong social, occupational, and academic impairments.

Internet-Assisted Parent Training Intervention for Disruptive Behavior in 4-Year-Old Children: A Randomized Clinical Trial.

IMPORTANCE: There is a large gap worldwide in the provision of evidence-based early treatment of children with disruptive behavioral problems. OBJECTIVE: To determine whether an Internet-assisted intervention using whole-population screening that targets the most symptomatic 4-year-old children is effective at 6 and 12 months after the start of treatment. DESIGN, SETTING, AND PARTICIPANTS: This 2-parallel-group randomized clinical trial was performed from October 1, 2011, through November 30, 2013, at a primary health care clinic in Southwest Finland. Data analysis was performed from August 6, 2015, to December 11, 2015. Of a screened population of 4656 children, 730 met the screening criteria indicating a high level of disruptive behavioral problems. A total of 464 parents of 4-year-old children were randomized into the Strongest Families Smart Website (SFSW) intervention group (n = 232) or an education control (EC) group (n = 232). INTERVENTIONS: The SFSW intervention, an 11-session Internet-assisted parent training program that included weekly telephone coaching. MAIN OUTCOMES AND MEASURES: Child Behavior Checklist version for preschool children (CBCL/1.5-5) externalizing scale (primary outcome), other CBCL/1.5-5 scales and subscores, Parenting Scale, Inventory of Callous-Unemotional Traits, and the 21-item Depression, Anxiety, and Stress Scale. All data were analyzed by intention to treat and per protocol. The assessments were made before randomization and 6 and 12 months after randomization. RESULTS: Of the children randomized, 287 (61.9%) were male and 79 (17.1%) lived in other than a family with 2 biological parents. At 12-month follow-up, improvement in the SFSW intervention group was significantly greater compared with the control group on the following measures: CBCL/1.5-5 externalizing scale (effect size, 0.34; P < .001), internalizing scale (effect size, 0.35; P < .001), and total scores (effect size, 0.37; P < .001); 5 of 7 syndrome scales, including aggression (effect size, 0.36; P < .001), sleep (effect size, 0.24; P = .002), withdrawal (effect size, 0.25; P = .005), anxiety (effect size, 0.26; P = .003), and emotional problems (effect size, 0.31; P = .001); Inventory of Callous-Unemotional Traits callousness scores (effect size, 0.19; P = .03); and self-reported parenting skills (effect size, 0.53; P < .001). CONCLUSIONS AND RELEVANCE: The study reveals the effectiveness and feasibility of an Internet-assisted parent training intervention offered for parents of preschool children with disruptive behavioral problems screened from the whole population. The strategy of population-based screening of children at an early age to offering parent training using digital technology and telephone coaching is a promising public health strategy for providing early intervention for a variety of child mental health problems.

Social media and gamification: Engaging vulnerable parents in an online evidence-based parenting program.

The aim of this study was to examine the feasibility (accessibility, engagement and impact) of adding social media and gaming features (e.g., social sharing with anonymity, badges to incentivize skills practice, an accredited facilitator for support) and access via smartphones to an evidenced-based parenting program, Triple P Online. The highly vulnerable population included 155 disadvantaged, high-risk parents (e.g., 76% had a family annual income of less than $15,000; 41% had been incarcerated; 38% were in drug/alcohol treatment; and 24% had had a child removed due to maltreatment). The ethnic groups most commonly identified were African American (24%) and Hispanic (66%). Respondents were primarily mothers (86%) from five community programs in Los Angeles. The study used a single group repeated measures design (pre, post, 6-month follow-up). Data collected included standardized self-report measures, post-intervention focus groups and interviews, website usage reports, and Google Analytics. Significant multivariate ANOVA time effects were found, demonstrating reductions in child behavioral problems, reduced lax/permissive and over-reactive parenting, and decreased parental stress. No effects were found for parental confidence, attributions, or depression and anxiety (which were in the normal range at baseline). Positive effects were maintained or improved at 6-month follow-up. The participants engaged in the online community and valued its flexibility, anonymity, and shared learning. This foundational implementation trial provides support for future rigorous evaluation of social media and gaming features as a medium for increasing parental engagement in evidence-based parenting programs online--a public health approach to protect and improve the development of vulnerable children.

First adaptation of coping power program as a classroom-based prevention intervention on aggressive behaviors among elementary school children.

Children with high levels of aggressive behavior create a major management problem in school settings and interfere with the learning environment of their classmates. We report results from a group-randomized trial of a program aimed at preventing aggressive behaviors. The purpose of the current study, therefore, was to determine the extent to which an indicated prevention program, Coping Power Program, is capable of reducing behavioral problems and improving pro-social behavior when delivered as a universal classroom-based prevention intervention. Nine classes (five first grade and four second grade) were randomly assigned to intervention or control conditions. Findings showed a significant reduction in overall problematic behaviors and in inattention-hyperactivity problems for the intervention classes compared to the control classes. Students who received Coping Power Program intervention also showed more pro-social behaviors at postintervention. The implications of these findings for the implementation of strategies aimed at preventing aggressive behavior in school settings are discussed.

Is parenting the mediator of change in behavioral parent training for externalizing problems of youth?

Change in parenting behavior is theorized to be the mediator accounting for change in child and adolescent externalizing problems in behavioral parent training (BPT). The purpose of this review is to examine this assumption in BPT prevention and intervention programs. Eight intervention and 17 prevention studies were identified as meeting all criteria or all but one criterion for testing mediation. Parenting behaviors were classified as positive, negative, discipline, monitoring/supervision, or a composite measure. Forty-five percent of the tests performed across studies to test mediation supported parenting as a mediator. A composite measure of parenting and discipline received the most support, whereas monitoring/supervision was rarely examined. More support for the mediating role of parenting emerged for prevention than intervention studies and when meeting all criteria for testing mediation was not required. Although the findings do not call BPT into question as an efficacious treatment, they do suggest more attention should be focused on examining parenting as a putative mediator in BPT.

Working together to solve disparities: Latina/o parents' contributions to the adaptation of a preventive intervention for childhood conduct problems.

Left untreated, conduct problems can have significant and long-lasting negative effects on children's development. Despite the existence of many effective interventions, U.S. Latina/o children are less likely to access or receive evidence-based services. Seeking to build the foundation to address these service disparities, the current study used a Community-Based Participatory Research approach to examine U.S. Latina/o parents' perceptions of the need for interventions to prevent childhood disruptive behaviors in their community in general, and of an existing evidence-based intervention-parent-child interaction therapy (PCIT)-in particular. Results suggest that parents recognize a need for prevention resources in their community and value most of the core features of PCIT. Nevertheless, important directions for potential adaptation and expansion of PCIT into a prevention approach were identified. Results point to several goals for future study with the potential to ameliorate the unmet mental health needs experienced by U.S. Latina/o families with young children at risk for developing conduct problems.

A field guide to real-time culture change: just "rolling out" a training program won't cut it.

Presented as a representative case of how to handle the disruptive behaviors of professionals in healthcare, this article describes the strategies of a systems approach with a five-phase model for culture change. The "large-scale, real-time" culture change process, based on our own evidence-based research on toxic behaviors and the research of others, has been demonstrated to be more effective than one-on-one feedback to change these behaviors. The real-time approach has been applied to other organizational situations--strategy formulation, change management, or service improvement--with more sustainable effects than simply training alone. This article will help your organization with four outcomes: understanding the rationale for a five-phase model for cultural change, describing the advantages of a real-time versus nonreal-time approach to change, identifying the how-to's for application within a systems approach, and articulating a clear evaluation process to sustain successful organizational culture change.

A comparison of online versus workbook delivery of a self-help positive parenting program.

A noninferiority randomized trial design compared the efficacy of two self-help variants of the Triple P-Positive Parenting Program: an online version and a self-help workbook. We randomly assigned families of 193 children displaying early onset disruptive behavior difficulties to the online (N = 97) or workbook (N = 96) interventions. Parents completed questionnaire measures of child behavior, parenting, child maltreatment risk, personal adjustment and relationship quality at pre- and post-intervention and again at 6-month follow up. The short-term intervention effects of the Triple P Online program were not inferior to the workbook on the primary outcomes of disruptive child behavior and dysfunctional parenting as reported by both mothers and fathers. Both interventions were associated with significant and clinically meaningful declines from pre- to post-intervention in levels of disruptive child behavior, dysfunctional parenting styles, risk of child maltreatment, and inter-parental conflict on both mother and father report measures. Intervention effects were largely maintained at 6-month follow up, thus supporting the use of self-help parenting programs within a comprehensive population-based system of parenting support to reduce child maltreatment and behavioral problems in children.

Does maintenance treatment matter?

This study examined the effects of a two-year maintenance treatment assessed at 1 and 2 years following Parent-child Interaction Therapy (PCIT). Sixty-one of 100 clinic-referred children (M age = 4 years, 4 months) originally diagnosed with oppositional defiant disorder (ODD) completed the standard treatment and were then randomized to PCIT maintenance treatment (MT) or to an assessment-only follow-up condition (AO). Rating scale and observational measures from fathers, mothers, and children were collected before and after standard treatment and at one- and two-year follow-up assessments. Maintenance treatment involved monthly telephone contacts from the original therapist focused on relapse prevention based on principles of PCIT. At the two-year follow-up, MT families showed few changes from post-treatment, as expected. However, the expected decrements for AO control families were not seen. Few differences between MT and AO were found at either follow-up assessment, and there were no significant differences in the rates of change during follow-up. The maintenance of gains among AO families may have resulted from the continuous enhancement of standard treatment or from inadvertent reinforcement for maintenance provided by the assessments of change alone.

A 10-year randomized controlled trial of the Early Risers conduct problems preventive intervention: effects on externalizing and internalizing in late high school.

OBJECTIVE: The purpose of this study was to examine the long-term effects of the Early Risers "Skills for Success" Conduct Problems Prevention Program (ER; August, Bloomquist, Realmuto, & Hektner, 2007), a multifaceted program targeting social, emotional, behavioral, and academic risk and protective factors to promote adaptive psychological development. METHOD: Based on the random assignment of their school, 245 kindergartners (mean age = 6.6 years, SD = 0.57; 68.6% male) with elevated teacher-rated aggressive behavior either participated in ER for 3 intensive years plus 2 booster years or served as controls. Participants were assessed annually during the intervention with teacher and parent reports and at 2 follow-up points. In the current study, 129 of the original participants were reassessed with diagnostic interviews in late high school (mean age = 16.3, SD = 0.52), and multiple imputation was used to deal appropriately with missing data. RESULTS: Program participants had significantly fewer symptoms of conduct disorder, oppositional defiant disorder, and major depressive disorder than did controls. The program's effect on increasing social skills and parent discipline effectiveness by Grade 3 mediated these effects. CONCLUSIONS: The results of this study provide further evidence of the long-term positive effects of multicomponent, elementary-age, targeted conduct problems prevention programs. Training children in social skills and parents in effective discipline are possible mechanisms to divert maladaptive developmental cascades.

A pilot study of a school-based prevention and early intervention program to reduce oppositional defiant disorder/conduct disorder.

UNLABELLED: Oppositional defiant disorder (ODD) or conduct disorder (CD) occurs when children's disruptive and antisocial behaviours start to interfere with their academic, emotional and/or social development. Recently, there has been a considerable investment to implement national school-based early intervention programs to help prevent the onset of ODD/CD. AIM: This paper describes the delivery of the Royal Children's Hospital, Child and Adolescent Mental Health Service and Schools Early Action Program: a whole school, multi-level, multidisciplinary approach to address emerging ODD/CD and pre- versus post-delivery assessment in 40 schools over a 4-year period (2007-2010). METHODS: All children from preparatory to grade 3 (ages 4-10 years) were screened for conduct problems (n = 8546) using the Strengths and Difficulties Questionnaire. Universal, targeted and indicated interventions were delivered in school settings. In total, 304 children participated in the targeted group program where the Child Behaviour Checklist was used as a pre- and post-intervention measure. Cohen's d effect sizes and a reliability change index were calculated to determine clinical significance. RESULTS: Significant reductions in both parent- and teacher-reported internalizing and externalizing symptoms were noted. Parent, teacher and child feedback were very positive. CONCLUSIONS: A future randomized controlled trial of the program would address potential placebo and selection bias effects.
