Developing Brain, Impulsivity and Compulsivity
Typical DevelopmentAttention Deficit Hyperactivity Disorder2 moreBackground: Impulsivity is acting 'without thinking.' Compulsivity is being overly inflexible. People vary in how impulsive or compulsive they are. Extreme versions of these behaviors play a role in mental disorders. Researchers want to study changes in the brain to learn more about these behaviors. Differences in genes may also play a role. Objective: To learn about genetic and brain features that explain why levels of impulsivity and compulsivity vary across people. Eligibility: People ages 6-80 Design: Participants will be screened with a medical history and medical record review. Participants will talk about their mental and behavioral development. They may discuss topics like drug use and sexual activity. They will complete surveys about their compulsivity and impulsivity. Parents of child participants may also complete these surveys. Participants may take memory, attention, and thinking tests. They may give blood or saliva samples for gene studies. Participants may have a magnetic resonance imaging scan. It will take pictures of their brain. The scanner is shaped like a cylinder. Participants will lie on a table that slides in and out of the scanner. A coil will be placed over their head. They will lie still, watch a movie, and play a game. Participants may have a magnetoencephalography scan. It records brain activity. Participants will sit in a room. A 'cone' of magnetic field detectors will be lowered around their head. They will rest and play a game. Participants may ask family members to join the study. Participants under age 25 may repeat these tests every 1-2 years until they turn 25 or until the study ends. For those over age 25, participation will last less than 1 month.
Big Feelings: A Study on Children's Emotions in Therapy
Anxiety DisordersDepressive Disorder7 moreThe goal of this clinical trial is to learn about how psychotherapy works for children and adolescents aged 8 - 15 with anxiety, depression, trauma, or disruptive behaviour. The main question it aims to answer is: • Is the biobehavioural regulation of negative emotion a transdiagnostic mechanism of treatment response in psychotherapy for children with anxiety, depression, trauma and/or disruptive behaviour? Children and their parents will be randomly assigned to an evidence-based, transdiagnostic treatment (the Modular Approach to Therapy for Children with Anxiety, Depression, Trauma, and Conduct Problems; MATCH-ADTC) or a waitlist control condition. Participants in both groups will complete a baseline assessment, weekly measures consisting of brief symptom scales and medication tracking, and quarterly assessments every 3 months. Following the intervention/waitlist period, our team will conduct post-test assessments. All assessments, except for the weekly surveys, will consist of symptom scales, clinical interviews, experimental tasks and physiological measures.
Multisite Prevention of Conduct Problems (Fast Track)
Conduct DisorderAnti-Social BehaviorThe primary aim of this project is to evaluate the effects of a comprehensive intervention to prevent severe and chronic conduct problems in a sample of children selected as high-risk when they first entered school. It is hypothesized that the intervention will have positive effects on proximal child behavior in middle school, and high school affecting long-term adolescent outcomes such as conduct disorder, juvenile delinquency, school dropout, substance use, teen pregnancy, relational competence with peers, romantic partners and parents, education and employment and social and community integration.
Intervening Early With Neglected Children
Conduct DisorderADHD1 moreThis study will assess early and middle childhood outcomes of an intervention for neglecting parents that was implemented in the children's infancy. We expect that parents who received the Attachment and Biobehavioral Catch-up Intervention in infancy will be more nurturing and will follow children's lead more than parents who received a control intervention, and that children will show better outcomes in attachment, inhibitory control, emotion regulation, and peer relations than children of parents who received the control intervention.
The Effectiveness of Forensic Outpatient Systemic Therapy: a Multiple Case Experimental Design

Investigating the Specificity of Neural Correlates for Emotion Processing Deficits in Conduct Disorder...
Autism-Spectrum DisorderConduct DisorderThis study is to investigate the differential and shared neural underpinnings of facial emotion processing within Conduct disorder (CD) and Autism-Spectrum disorder (ASD) and to investigate the interaction between deficits in emotion processing and dysfunctional cognitive control processes. Differences in emotion processing and the underlying neural underpinnings of such differences will be assessed by means of functional magnetic resonance imaging (fMRI) without any contrast agent, combined with adapted emotion processing paradigms and eye tracking techniques.
Methylphenidate vs. Risperidone for the Treatment of Children and Adolescents With ADHD and Disruptive...
Attention Deficit/Hyperactivity DisorderOppositional Defiant Disorder1 moreAttention Deficit/Hyperactivity Disorder (ADHD) is one the most prevalent mental disorders among children and adolescents, with a prevalence of 5% in western culture. The basics of the disorder: inattentive and hyperactive/impulsive behaviors that manifest in a variety of settings causing a dysfunction in everyday life. ADHD can be subdivided into three sub-types: predominantly inattentive, predominantly hyperactive/impulsive or combined type. Common co-morbidities of ADHD are disruptive disorders; Oppositional defiant disorder (ODD) being the major one with about half of children with the combined sub-type ADHD and about a quarter of children with the predominantly inattentive also suffering from ODD. Conduct disorder is a co-morbidity for about a quarter of children with the combined sub-type ADHD. The co-occurrence of these disorders is thought to have a negative effect on the outcome of both of them. Methylphenidate (MPH), short or long acting, is the mainstay of medical treatment for ADHD patients, it's efficacy proven in a variety of studies. It should be noted that MPH has also been proven to have a beneficial effect on children with disruptive behaviors. For children with disruptive disorders Risperidone is the mainstay of medical treatment, and has been proven in clinical trials. To the best of their knowledge, a "head to head" study comparing these two drugs for the treatment of pediatric patients with ADHD and co-morbidity of disruptive disorders was never done before. The investigators aim is to examine the efficacy and tolerability of MPH vs. Risperidone in this population. In addition, the investigators will apply DSM5's cross cutting symptom measures scales is order to further define this unique subset of patients. Disruptive mood dysregulation disorder (DMDD) is a new diagnosis in the latest version of the diagnostic and statistical manual (DSM5). It's main features: sever recurrent temper outbursts that are inconsistent with developmental level and occur on average three times a week, the outbursts occur in at least two settings and the mood between outbursts is irritable or angry. This diagnosis is in the differential diagnosis of ADHD with disruptive disorders.
Mentalization-based Training for Adolescents With Conduct Disorder (MBT-CD)
Conduct DisorderA feasibility and pilot trial to investigate the feasibility of a newly manualized psychotherapy "Mentalization-Based Training for Adolescents with Conduct Disorder (MBT-CD)"
Randomized Feasibility Trial of Mind My Mind
AnxietyAnxiety Disorders6 moreIn this feasibility RCT of the modular and flexible cognitive and behavioural therapy (Mind My Mind, MMM) compared with treatment as usual, the overall research aim was to explore the trial design and the acceptability of the assessments, interventions and outcome measures among children, parents, teachers and therapists, and secondly to provide data to estimate the parameters required to design a definitive RCT.
Randomized Control Trial of an Animal-Assisted Intervention With Adjudicated Youth
Conduct DisorderDepression1 moreThe project involves testing the efficacy of an animal-assisted intervention (AAI). The AAI consists of a 10-week program in which adjudicated adolescents train shelter dogs and will be compared to a dog walking control group matched for educational content and dog contact time. The investigators expect that the AAI will result in improved empathy skills and that dog attachment will explain these findings. The investigators also explore the extent to which the AAI will improve internalizing and externalizing symptoms in these adolescents.
