Impact of treatment of ADHD on intimate partner violence (ITAP), a study protocol.

BACKGROUND: Attention-Deficit/Hyperactivity Disorder (ADHD) in adults is one of the predictive and treatable risk factors for delinquency, including intimate partner violence (IPV). Effective treatment of IPV needs to address personal dynamic risk factors, offender typology, and dynamics of the domestic violence. It is unknown whether treatment of ADHD symptoms contributes to a decrease in IPV. The ITAP study aims to investigate the relationship between treatment of ADHD symptoms and IPV in patients in forensic mental health care. Moreover, this study examines the role of comorbid psychopathology, subtype of the offender, and dynamics of the domestic violence. METHODS/DESIGN: The ITAP study is a longitudinal observational study. Participants are followed one year through various assessments: one before starting treatment (t0), and four during treatment (8, 16, 24 and 52 weeks after start of the treatment). All participants receive treatment for IPV, ADHD, and comorbid psychopathology, if present. The primary outcome measure is the change in severity of IPV; the primary predictive variable is the change in severity of ADHD symptoms. The secondary outcome measure is the observation of the therapist about change in the offender's general violent behaviour, within and outside the partner relationship. Data are analysed in a multiple regression model with change in severity of IPV as the dependent variable and change in severity of ADHD symptoms as the primary predictor. Other predictive variables taken into account in the analyses are presence of comorbid psychopathology and personality disorder, subtype of the offender, and dynamics of the domestic violence. In addition, compliance with treatment and content of the treatment are documented. DISCUSSION: Research on the treatment process of IPV offenders and victims is complicated by many factors. This observational design will not allow inferences about causality but may reveal clinically important factors that contribute to more effective treatment of IPV.

Cross-sectional study into the costs and impact on family functioning of 4-year-old children with aggressive behavior.

Early-onset aggressive behavior is known for its negative developmental consequences, and the associated high costs for families, the health care system and wider society. Although the origins of aggressive behavior are to be found in early childhood, the costs incurred by aggressive behavior of young children have not been studied extensively. The present study aimed to investigate whether preschool children with a high level of aggressive behavior already differ in the generated amount of costs and impact on family functioning from children with lower levels of aggressive behavior. A population-based sample of 317 preschool children was divided into four groups with different levels of aggression (moderate, borderline, clinical). Parents filled out questionnaires to assess service use (lifetime and past 3 months) and impact on family functioning. Over the past 3 months as well as over the first 4 years of life, children with a clinical level of aggression were more costly than children with a low level of aggression (mean total costs over the past 3 months: low € = 167,05 versus clinical € = 1034,83 and mean lifetime costs: low € = 817,37 versus clinical € = 1433,04), due to higher costs of services used by the child. In addition, families of children with a borderline or clinical level of aggressive behavior reported more impairment in their daily functioning than families of children with lower levels of aggression. The findings demonstrate that a high level of aggressive behavior results in high costs and impaired family functioning in the preschool years already.

The Impact of ADHD Treatment on Intimate Partner Violence in a Forensic Psychiatry Setting.

Objective: The current longitudinal impact of treatment of ADHD on intimate partner violence (ITAP) study aims to investigate whether decrease of ADHD symptoms is associated with reduction of intimate partner violence (IPV) frequency in IPV offenders with ADHD in a forensic psychiatry setting. Method: Of n = 209 offenders of IPV with ADHD, frequency of IPV and ADHD symptoms were assessed at the 8th, 16th, 24th, and 52nd weeks of their combined treatment for ADHD and IPV. Results: We observed a significant decrease of self-reported ADHD symptoms (large effect size, d ≥ 0.80) and all IPV outcomes (small, d > 0.20, to large, d > 0.80, effect sizes). The decrease in IPV was mainly associated with the decrease in ADHD symptoms. Conclusion: As IPV treatment alone is not effective in the reduction of IPV in forensic psychiatry, we now have strong indications that the combined treatment of adult ADHD and IPV is more effective in offenders with ADHD.

ADHD in Childhood and/or Adulthood as a Risk Factor for Domestic Violence or Intimate Partner Violence: A Systematic Review.

Objective: To date, treatment programs for adult domestic violence (DV) or intimate partner violence (IPV) have had minimal impact. To make treatment more effective, programs should be adjusted to psychopathology of the offender. As emotional lability and poor emotional self-regulation and self-control are common features of ADHD, it may play a pivotal role as a predictor for adult DV/IPV. Method: This systematic review synthesizes the available evidence for childhood and/or adult ADHD being a risk factor for DV/IPV. Results: Four case control studies and three cohort studies were included in the review. Although three case control studies showed positive associations between childhood and/or adult ADHD and adult DV/IPV, two did insufficiently control for the presence of comorbid Conduct Disorder (CD) or Antisocial Personality Disorder (ASPD). Conclusion: Cohort studies identified hyperactive, impulsive, and inattention symptoms as risk factors for adult IPV. CD and ASPD were regarded as mediators in three studies.

Executive functions in preschool children with aggressive behavior: impairments in inhibitory control.

The question whether executive function (EF) deficits in children are associated with conduct problems remains controversial. Although the origins of aggressive behavior are to be found in early childhood, findings from EF studies in preschool children with aggressive behavior are inconsistent. The current study aimed to investigate whether preschool children with aggressive behavior show impairments in EF. From a population-based sample, 82 preschool children who were showing aggressive behavior as indicated by scores at or above the 93rd percentile on the Aggressive Behavior Scale of the CBCL 1 1/2-5 were selected. These children with aggressive behavior were matched on IQ to a group of typically developing control children (N = 99). Six neuropsychological tasks were administered to assess set shifting, inhibition, working memory and verbal fluency. A factor analysis was conducted which yielded one clear factor: inhibition. Aggressive preschool children showed poorer performance on this inhibition factor than control children and boys performed worse on this factor than girls. This association between aggressive behavior and inhibition deficits was maintained after controlling for attention problems. In addition, gender differences in all EFs measured were found with boys exhibiting more impairment in EF than girls. These findings demonstrate that preschool children with aggressive behavior show impairments in inhibition, irrespective of attention problems.

Sustained effects of incredible years as a preventive intervention in preschool children with conduct problems.

The present study evaluated preventive effects of the Incredible Years program for parents of preschool children who were at risk for a chronic pattern of conduct problems, in the Netherlands. In a matched control design, 72 parents of children with conduct problems received the Incredible Years program. These families (intervention group) were compared with 72 families who received care as usual (control group). Two years after termination of the intervention, it appeared that observed and selfrated parenting skills were significantly improved in the intervention group. Likewise, in this group, observed child conduct problems showed sustained intervention effects. The decrease in observed critical parenting mediated the decrease in observed child conduct problems over time. In addition, it appeared that parental influence increased over time.

Facial EMG and heart rate responses to emotion-inducing film clips in boys with disruptive behavior disorders.

We examined aspects of emotional empathy across different physiological response systems in boys with disruptive behavior disorders (DBD) and normal controls. Heart rate (HR) and electromyographic (EMG) reactivity in zygomaticus major and corrugator supercilii muscles were monitored during sadness-, anger-, or happiness-inducing film clips. Relative to controls, DBD boys showed significantly less HR reduction during sadness, and a smaller increase in corrugator EMG activity both during sadness and anger. No significant group differences emerged in HR and zygomaticus EMG responsivity during happiness. We also examined cardiac activity at rest and found higher resting HR and lower respiratory sinus arrhythmia in DBD boys compared to controls. Findings give evidence for a selective impairment in empathy with sadness and anger (not happiness) among DBD boys who exhibit relatively high levels of anxiety and poor emotional control.
