Stability of the effects of a social competence training program for children with oppositional defiant disorder/conduct disorder: a 10-month follow-up

The stability and effectiveness of the Treatment Program for Children with Aggressive Behavior (THAV) in terms of reducing behavioral problems in children with oppositional defiant disorder (ODD) and conduct disorder (CD) were examined at a 10-month follow-up (FU). A total of 76 families and their children (boys aged 6-12 years), who previously participated in a randomized controlled trial comparing THAV with an active control group, took part in the 10-month FU assessment. Outcome measures were rated by parents and included the evaluation of child aggressive behavior, prosocial behavior, problem-maintaining and problem-moderating factors, and comorbid symptoms. Linear mixed models for repeated measures (MMRM) were conducted. The results revealed that THAV effects remained stable (problem-maintaining and problem-moderating factors; comorbid symptoms) and even partially improved (aggressive behavior; ADHD symptoms) over the FU period. Additionally, the differences between the THAV intervention group and the control group, which were apparent at the end of the treatment (post), mainly also remained at the FU assessment. It can be concluded that THAV is an effective and stable intervention for boys aged 6-12 years with ODD/CD.

Parent-Child Inpatient Treatment in Child and Adolescent Mental Healthcare: Predictors of Child Outcomes

Family inpatient units in child and adolescent mental health (CAMH) services engage all admitted family members in the treatment of children's symptoms. Studies demonstrated improvements in child and family functioning following family inpatient treatment, but evidence regarding predictors of treatment outcome is lacking. We analyzed data of families (n = 66) who received a four-week inpatient treatment for families with severe parent-child interaction problems. Hierarchical linear regression analyses revealed that parents who recalled harsher parenting practices of their own fathers reported greater improvements in their children's externalizing and internalizing problems. Greater improvements in externalizing problems were further predicted by lower parental educational level, less adverse impacts of stressful life events, and less internalizing child problems prior to admission. We therefore conclude that family inpatient treatment was particularly effective for children in families with lower parental education and a history of harsh parenting.

Long-Term Effects of an Oligoantigenic Diet in Children with Attention-Deficit/Hyperactivity Disorder (ADHD) on Core Symptomatology

In the early 1920s, it was discovered that nutrition is associated with what is known today as Attention-Deficit/Hyperactivity Disorder (ADHD) and that certain foods can worsen the symptoms. In previous studies, approximately 60% of the participants experience at least a 40% reduction in ADHD symptoms after an oligoantigenic diet (OD). The purpose of this study was to evaluate ADHD symptoms in children approximately 3.5 years after completing a 4-week oligoantigenic diet. Among 28 participants who completed the 4-week diet, 21 were re-assessed for this study after 3.5 years. The severity of ADHD symptoms was assessed with the ADHD-Rating-Scale-IV (ARS). Of 21 participants, 14 fulfilled the responder criterion, whereas 7 did not. At follow-up, 28% of the participants were taking medication. The mean ARS total score improved significantly from T1: M = 29.62 (SD = 9.80) to T2: M = 15.86 (SD = 8.56) between the time points before and after the diet (d = -1.91). There was also a lower ARS total score at the follow-up T5: M = 16.00 (SD = 10.52) compared to before the diet (d = -1.17). This study shows that individually adjusted nutrition significantly improved the ADHD symptomatology of the participants long-term. This suggests that an oligoantigenic diet with subsequent individual nutritional recommendations could become an additional treatment option for children with ADHD.

Oligoantigenic Diet Improves Children's ADHD Rating Scale Scores Reliably in Added Video-Rating

OBJECTIVES

The influence of food intake on behavioural disorders was already described in the early 20th century. Elimination of individually allergenic food items from individual diets ["oligoantigenic diet" (OD)] showed promise to improve attention-deficit/hyperactivity disorder (ADHD) symptoms. However, only few of the positive results were evaluated by blinded symptom rating. Therefore the present study's purpose was to evaluate the reliability of a non-blinded rating of the ADHD Rating Scale IV (ARS) for the assessment of OD effects in comparison to a blinded rating of the ARS based on pseudonymized video recordings.

METHODS

Ten children (8m/2f) aged 8 to 14 with ADHD according to ICD-10 participated in an uncontrolled, open-label dietary intervention study. Food items, commonly related to intolerances, were eliminated for four weeks. Participants with > 40% improvement in the ARS between T1 (before the diet) and T2 (after the diet) were defined as responders. Nutrients with individual relevance to ADHD symptoms were identified in a following reintroduction phase (T3-T4) lasting 8-16 weeks. The ARS was completed by a non-blinded child and adolescent psychiatrist (T0-T4). Sessions were recorded on video, pseudonymized, and evaluated by three blinded raters. Complete data were captured for eight children. The inter-rater reliability between the non-blinded therapist and every blinded rater was determined by the intra-class correlation coefficient (ICC). Correlations according to Pearson and Spearman between the non-blinded and blinded rating were calculated for each rater.

RESULTS

Two blinded raters and the non-blinded rater considered 5 of 8 (62.5%) children as responders, whereas one blinded rater disagreed as to the success of one case thus considering only 4 of 8 children as responders to the diet. Inter-rater reliability was assessed after each rater having scored 33 videos: The intra-class coefficients were >.9 for all raters (rater 1: ICC=.997, rater 2: ICC=.996, rater 3: ICC=.996) and the Spearman rho between the raters were high (n=33; rater 1: rho =.989, p<.0001, rater 2: rho=.987, p<.0001, rater 3: rho=.984, p<.0001), respectively.

DISCUSSION

As both, blinded and non-blinded ratings of the ARS, revealed relevant significant improvement of ADHD scores in children following an OD in this uncontrolled trial, Randomized controlled trials appear as highly desirable in order to replicate these improvements and to establish reliable and unbiased effect sizes thereby fostering further more objective confirmatory measurements.

Differenzielle Analysen zum Zusammenhang zwischen Kreativität und ADHS bei Kindern und Jugendlichen

Zusammenfassung. Befunde zur Kreativität bei Kindern und Jugendlichen mit ADHS sind widersprüchlich. Zur Erfassung von Kreativität wird oft auf quantitative Leistungsmaße wie divergentes Denken in Speed-Tests zurückgegriffen anstelle von qualitativen Aspekten wie Unkonventionalität und Humor. Diese Studie untersucht, ob sich Kinder und Jugendliche mit ADHS hinsichtlich quantitativer und qualitativer Kreativitätsmerkmale von einer Kontrollgruppe unterscheiden. Die Stichprobe schließt N = 71 Kinder und Jugendliche (10 – 14 Jahre) ein, davon 17 mit klinischer ADHS-Diagnose und 16 mit ADHS-Symptomen gemäß DISYPS-II. In einem standardisierten Kreativitätstest erreichen die ADHS-Gruppen unabhängig von Alter und Geschlecht signifikant bessere Gesamtleistungen als die Kontrollgruppe. Unterschiede bestehen vor allem in den Bereichen Humor und emotionale Expressivität zeichnerischer Darstellungen. Die Ergebnisse unterstreichen die Bedeutung ressourcenorientierter Perspektiven auf Kinder und Jugendliche mit ADHS.

Cross-Informant Disagreement on Behavioral Symptoms in Adolescent Attention-Deficit/Hyperactivity Disorder and Its Impact on Treatment Effects

Abstract. In assessing adolescent behavior difficulties, parents, teachers, and the adolescents themselves are key informants. However, substantial disagreement has been found between informants. Specifically, children with attention-deficit/hyperactivity disorder (ADHD) tend to overestimate their competencies, also known as “positive (illusionary) bias.” This study compared parent, teacher, and adolescent ratings of ADHD and other behavioral symptoms in a sample of 114 adolescents with ADHD. Further, the effect of cross-informant disagreement (CID) on treatment outcomes was investigated in a subsample of 54 adolescents who had undergone a training and coaching intervention. Overall, there was moderate agreement among informants. Parent and adolescent ratings were more strongly correlated with each other than with teacher ratings. The strongest discrepancy was found between teacher and adolescent ratings on prosocial behavior. This discrepancy explained 12% of the variance in parent-rated ADHD symptom severity after the intervention. The treatment was less effective in participants with high teacher-adolescent disagreement on prosocial behavior (d = 0.41) than with low disagreement (d = 0.98). These findings suggest that professionals working with adolescents with ADHD should consider multiple sources of information before initiating treatment and pay attention to cross-informant disagreements because these may indicate a risk of diminished treatment effects.

[Diagnosis of auditory processing disorders in children]

Despite normal hearing thresholds in pure tone audiometry, 0.5-1 % of children have difficulty understanding what they hear. An auditory processing disorder (APD) can be assumed, which should be clarified and treated. Based on a selective literature search in the PubMed and Scopus databases using the term "auditory processing disorder", several consensus papers are discussed. Numerous studies on APD have revealed partially contradicting results, thus fueling critical discussion regarding validity and reliability-of specific audiometric APD methods and the APD construct in particular. In order to correctly advise parents and, where necessary, treat affected children, otorhinolaryngologists, phoniatrists, and pediatric audiologists must understand the psychometric properties of applied tests and have knowledge of current discussion. Diagnosis is generally a multistep interdisciplinary process.

[WISC-IV performances of young male subjects with AD(H)D, the benefits of applying cognitive profile analysis to diagnostics]

Objective

Studies suggest that children and adolescents suffering from AD(H)D show a specific WISC-IV profile in comparison to subjects of the same age group without any mental disorder. The present study compares the cognitive profiles of male subjects with AD(H)D to those of a clinical control group. The benefits of applying an ADHD specific cognitive profile analysis to differential diagnostics are analyzed.

Method

The WISC-IV profiles of 50 male subjects with AD(H)D (8 to 15 years) were compared with the profiles of 54 male children and adolescents(7 to 16 years) with other mental disorders. In addition, subgroup differences within the AD(H)D group were investigated.

Results

Subjects with AD(H)D showed a significant lower processing speed than the control group. Within the AD(H)D group, patients with ADD showed the lowest speed index. There were no group differences in total IQ and other WISC-IV indexes.

Conclusions

A WISC-IV profile analysis is not a suitable instrument to certainly confirm or exclude an AD(H)D diagnosis. Nevertheless, the results of the present study speak for considering the WISC-IV profile in the diagnosis of AD(H)D as it increases the sensitivity of the clinical diagnostic process and provides useful indicators for differential diagnosis.

Training Problem Solving and Organizational Skills in Adolescents With Attention-Deficit/Hyperactivity Disorder: A Randomized Controlled Trial

Attention-deficit/hyperactivity disorder (ADHD) is a highly prevalent psychiatric disorder in adolescence and results severe impairment. Few psychosocial interventions aim at ADHD in adolescence and are rarely evaluated in randomized controlled trials (RCTs). Therefore, an intervention combining adolescent-directed problem-solving and organizational skills training with behavioral parent and teacher training has been developed. Its efficacy in comparison to waiting list and active controls is reported.

One hundred thirteen adolescents (mean age = 13.99 years) with ADHD were randomly assigned to the training, a waiting list or an active control condition (progressive muscle relaxation [PMR]). Parents and teachers rated ADHD symptoms, academic enablers, and comorbid problems before and after. Results: The training significantly reduced ADHS symptoms and parent- and teacher-rated internalizing problems and increased teacher rated academic enablers compared to waiting list controls. Compared to active controls, results were in the range of small nonsignificant effects. A skills training is an efficacious treatment for adolescent ADHD, however, not significantly superior to PMR. Contrasts between both interventions need to be further investigated.

Parent-child inpatient treatment for children with behavioural and emotional disorders: a multilevel analysis of within-subjects effects

BACKGROUND

The importance of parental involvement in child treatment is well-established. Several child psychiatric clinics have, therefore, set up inpatient family units where children and parents are both actively involved in the treatment. Unfortunately, evidence supporting the benefits of these units is sparse.

METHODS

We evaluated the effectiveness of inpatient treatment for families with severe parent-child interaction problems in a child psychiatric setting. Consecutive admissions to the parent-child ward (N = 66) were studied. A within-subjects design was used with four assessment points (baseline, admission, discharge, four-week follow-up). Outcome measures were 1) parent and teacher ratings of child behaviour, and 2) parent self-ratings of parenting practices, parental strains and parental mental health. Data were analyzed using multilevel modelling for longitudinal data (piecewise growth curve models).

RESULTS

All parent-rated measures improved significantly during the four-week treatment period (d = 0.4 - 1.3). These improvements were significantly greater than those observed during the four-week pre-admission period. In addition, benefits were maintained during the four-week follow-up period. Only parents' self-efficacy in managing their child's behaviour showed continued improvement during follow-up. Teacher ratings of children's disruptive behaviour at school were stable during the pre-admission period and showed significant improvements at follow-up (d = 0.3 - 0.4).

CONCLUSIONS

We conclude that parent-child inpatient treatment has positive effects on child and parent behaviour and mental health, and can therefore be recommended for children with behavioural and emotional disorders and severe parent-child interaction problems.

An objective measure of hyperactivity aspects with compressed webcam video

BACKGROUND

Objective measures of physical activity are currently not considered in clinical guidelines for the assessment of hyperactivity in the context of Attention-Deficit/Hyperactivity Disorder (ADHD) due to low and inconsistent associations between clinical ratings, missing age-related norm data and high technical requirements.

METHODS

This pilot study introduces a new objective measure for physical activity using compressed webcam video footage, which should be less affected by age-related variables. A pre-test established a preliminary standard procedure for testing a clinical sample of 39 children aged 6-16 years (21 with a clinical ADHD diagnosis, 18 without). Subjects were filmed for 6 min while solving a standardized cognitive performance task. Our webcam video-based video-activity score was compared with respect to two independent video-based movement ratings by students, ratings of Inattentiveness, Hyperactivity and Impulsivity by clinicians (DCL-ADHS) giving a clinical diagnosis of ADHD and parents (FBB-ADHD) and physical features (age, weight, height, BMI) using mean scores, correlations and multiple regression.

RESULTS

Our video-activity score showed a high agreement (r = 0.81) with video-based movement ratings, but also considerable associations with age-related physical attributes. After controlling for age-related confounders, the video-activity score showed not the expected association with clinicians' or parents' hyperactivity ratings.

CONCLUSIONS

Our preliminary conclusion is that our video-activity score assesses physical activity but not specific information related to hyperactivity. The general problem of defining and assessing hyperactivity with objective criteria remains.

Adaptive multimodal treatment for children with attention-deficit-/hyperactivity disorder: an 18 month follow-up

The Cologne Adaptive Multimodal Treatment (CAMT) study demonstrated that adaptive and individually tailored multimodal treatment for attention-deficit/hyperactivity disorder (ADHD) [consisting of behavior therapy (BT) and/or stimulant medication] is highly effective. This study reports findings of the 18 month follow-up assessment. Parents and teachers completed broad range behavior scales (Child Behavior Checklist/Teacher Report Form) and standardized ADHD and oppositional defiant disorder/conduct disorder symptom rating scales. Children that used medication to treat ADHD at follow-up (N = 32) and those that did not (N = 34) were analyzed separately. Parents did not report significant changes in child behavior from posttest to follow-up. Teacher ratings revealed some aggravation of ADHD symptoms in children that received medication, but this was not significant after Bonferroni correction. The initial advantage of combined treatment over BT was no longer evident. It can be concluded that treatment for ADHD that is tailored to the assessed needs of children results in large treatment effects that are maintained for at least 18 months.

Aarskog-Scott syndrome: a novel mutation in the FGD1 gene associated with severe craniofacial dysplasia

Aarskog syndrome (AAS) is an X-linked human disease that affects the skeletal formation and embryonic morphogenesis and is caused by mutations in the FGD1 gene. Patients typically show distinctive skeletal and genital developmental abnormalities, but a broad spectrum of clinical phenotypes has been observed. We report here on the clinical and molecular analysis of a family that reveals a novel FGD1 mutation in a 9-year-old boy displaying extreme craniofacial dysplasia associated with attention deficit hyperactivity disorder. Sequencing of FGD1 revealed a novel mutation in exon 7 at position c.1468 C > T in the index patient, leading to a stop codon in the highly conserved RhoGEF gene domain. His mother and maternal grandmother were also found to be heterozygous for this FGD1 mutation.

CONCLUSION

Our results identify a novel mutation of FDG1 in a family with Aarskog syndrome and underscore the phenotypical variability of this condition.

DSM-5 – Aufmerksamkeitsdefizit-/Hyperaktivitätsstörungen

Die Modifikationen, die im DSM-5 bei den Kriterien für die Diagnose einer Aufmerksamkeitsdefizit-/Hyperaktivitätsstörung (ADHS) vorgenommen wurden, werden vorgestellt und kritisch diskutiert. Die wichtigsten Veränderungen beziehen sich auf den Beginn der Symptomatik, die Reduktion der Anzahl der notwendigen Kriterien ab dem Alter von 17 Jahren und die Streichung von Autismusspektrumstörungen als Ausschlussdiagnose. Diese Veränderungen sind überwiegend zu begrüßen, bei der Heraufsetzung des Alters für den Störungsbeginn müssen jedoch auch problematische Aspekte bedacht werden.

Nonword reading and Stroop interference: what differentiates attention-deficit/hyperactivity disorder and reading disability?

BACKGROUND

Attention deficits and impaired reading performance co-occur more often than expected by chance; however, the underlying mechanism of this association still remains rather unexplored.

METHOD

In two consecutive studies, children aged 8 to 12 years with attention-deficit/hyperactivity disorder (ADHD) and children with reading disability (RD) were examined using a 2 (ADHD versus no ADHD) × 2 (RD versus no RD) factorial design. To further delineate deficient interference control from reading processes, we used a newly developed self-paced word/nonword reading task (Experiment 1, n = 68) and a modified computerized Stroop paradigm, including an orthographic phonological neighbor (OPN) condition (Experiment 2, n = 84).

RESULTS

RD (compared to non-RD groups) was associated with impairments in both word and nonword reading, while children with ADHD also showed impaired nonword reading. In the Stroop task, RD, but not ADHD, had a significant impact on task performance. Interestingly, a significant interaction between ADHD, RD, and task condition emerged, which was due to particularly slower reaction times to nonwords in children with RD only, while task performance in children with comorbid ADHD and RD resembled that of ADHD only.

CONCLUSIONS

Thus, our results demonstrate that impairments in nonword reading were not specific to RD but were also present in children with ADHD. In addition, RD and not ADHD was characterized by poor interference control in the Stroop task. These findings question whether unique cognitive deficits are specific to either ADHD or RD.

Self-regulation strategies support children with ADHD to overcome symptom-related behavior in the classroom

Children with attention deficit hyperactivity disorder (ADHD) suffer from self-regulation deficits that cause inattention, impulsivity, and hyperactivity. Self-regulation interventions may address these deficits, but to date, only few empirical studies have examined their benefits for children with ADHD in everyday life. The present study investigated three classroom interventions to promote self-regulation and tested their benefit on self-regulatory competencies (assessed with an ADHD questionnaire) in children with ADHD. Students of a special education school for children with ADHD participated in the intervention study that included three sessions (Session 1: Goal Intention or Goal Intention + If-Then Plan; Session 2: Goal Intention + If-Then Plan; Session 3: Goal Intention + If-Then Plan + Self-Monitoring). Teacher-rated self-regulatory competencies were assessed both before and after the intervention sessions. Children with ADHD had better self-regulatory competencies after their first Goal Intention + If-Then Plan Session, but lasting intervention effects were found only when children started with a mere goal intention session.

Reduced cortisol in boys with early-onset conduct disorder and callous-unemotional traits

BACKGROUND

A growing body of evidence suggests an association between altered hypothalamic-pituitary-adrenal axis reactivity and the development of persistent antisocial behavior in children. However the effects of altered cortisol levels remain poorly understood in the complex context of conduct disorder, callous-unemotional (CU) personality traits, and frequent comorbidities, such as attention deficit hyperactivity disorder (ADHD). The aim of the current study was to investigate associations among CU traits, antisocial behavior, and comorbid ADHD symptomatology with cortisol levels in male children and adolescents.

METHODS

The study included 37 boys with early-onset conduct disorder (EO-CD, mean age 11.9 years) and 38 healthy boys (mean age 12.5 years). Participants were subjected to multiple daytime salivary cortisol measurements and a psychometric characterization.

RESULTS

Subjects in the EO-CD group with elevated CU traits showed a diminished cortisol awakening response compared to healthy participants. In the EO-CD group, high CU traits and impulsivity were associated with decreased diurnal cortisol levels, while associations with antisocial behavior were not detected. The cortisol awakening response was significantly inversely associated with hyperactivity (P = 0.02) and marginally significant with CU traits (P = 0.07).

CONCLUSIONS

These results indicate a specific association between CU traits and a diminished stress response, which is not explained by antisocial behavior in general.

Comparison of the efficacy of two different modified release methylphenidate preparations for children and adolescents with attention-deficit/hyperactivity disorder in a natural setting: comparison of the efficacy of Medikinet(®) retard and Concerta(®)--a randomized, controlled, double-blind multicenter clinical crossover trial

OBJECTIVE

The comparison of the efficacy of Medikinet(®) retard and Concerta(®) trial was a multisite, randomized, double-blind, crossover trial that aimed at comparing the effects of two different modified release methylphenidate preparations (Medikinet retard: 50% immediate release (IR); Concerta: 22% IR) in a natural setting across the day in 113 randomized children and adolescents with attention-deficit/hyperactivity disorder (age range 6-16 years). The duration of the study per patient was 3 weeks.

METHODS

The primary outcome variable was the German version of the "Swanson, Kotkin, Agler, M-Flynn, and Pelham scale" in the first 3 hours of school as assessed by teachers.

RESULTS

Medikinet retard with a higher IR component than Concerta (and an equivalent daily dose) was superior to Concerta (p=0.0009), and Medikinet retard with similar IR components in the morning as Concerta (but a lower daily dose) was noninferior to Concerta with regard to the primary outcome. Further, exploratory analyses on teacher and parent ratings on attention-deficit/hyperactivity disorder and on externalizing symptoms during the day revealed no evidence for the superiority of Concerta over Medikinet retard in an equivalent daily dosage throughout the day.

CONCLUSION

Children and adolescents may be treated with a lower daily dose of Medikinet retard (which has a similar IR component as Concerta) without resulting in a clinically relevant worse effect during school time.

Neurocognitive performance in children with ADHD and OCD

Attention-deficit/hyperactivity Disorder (ADHD) and obsessive-compulsive disorder (OCD) have both been linked to dysfunction in the cortico-striato-thalamo-cortical circuitry (CSTCC). However, the exact nature of neurocognitive deficits remains to be investigated in both disorders. We applied two neuropsychological tasks that tap into different functions associated with the CSTCC, namely a serial reaction time (SRT) task, developed to assess implicit sequence learning, and a delay aversion (DA) task in order to assess abnormal motivational processes. The performance data of boys with ADHD (n=20), OCD (n=20) and healthy controls (n=25), all aged 10-18 years, were compared. Subjects with ADHD less frequently chose the larger, more delayed reward compared to those with OCD and controls, while subjects with OCD showed impaired implicit learning. In contrast, the ADHD group was unimpaired in their implicit learning behavior and the OCD group was not characterized by a DA style. Within the OCD-group, severity of obsessions was associated with implicit learning deficits and impulsive symptoms with DA in the ADHD-group. This double dissociation highlights the distinct cognitive dysfunctions associated with ADHD and OCD and might possibly point to different neural abnormalities in both disorders.

An observational study of once-daily modified-release methylphenidate in ADHD: effectiveness on symptoms and impairment, and safety

ADHD affects over 5% of children worldwide. It is typically treated with stimulant medications, and methylphenidate (MPH) is the most commonly prescribed. This study investigated the effectiveness, on symptoms and impairment, and safety of Equasym XL(®), a combination of 30% immediate-release and 70% modified-release MPH, in the treatment of ADHD in daily clinical practice. This open-label, observational, post-marketing surveillance study was conducted in 169 centres in Germany. Eligible patients, aged 6-17 years, were diagnosed with ADHD and about to begin treatment with Equasym XL(®). Effectiveness was assessed by physicians using the clinical global impression (CGI) severity and improvement scales; teachers and parents completed questionnaires evaluating ADHD symptoms and behavioural problems (DAYAS, FBB-ADHD and SDQ-P). Assessments were carried out at baseline, after 1-3 and 6-12 weeks of treatment. Of 852 enrolled patients, 822 were evaluable; 25.30% were treatment naïve, 69.84% had previously received different MPH formulations, and 4.87% had received other medications. ADHD symptoms improved from baseline to last visit for the majority of patients for all outcome measures. According to physician ratings of core ADHD symptoms, 75.73% of patients showed improvements on the CGI-Improvement scale, 17.77% had no change, and 6.50% worsened. In teacher and parent ratings, the effectiveness of Equasym XL(®) was rated better than prior therapy at all measured time points across the day, particularly late morning (teachers) and early afternoon (parents). Equasym XL(®) was generally well tolerated; only 3.16% of patients permanently discontinued treatment due to adverse events. Equasym XL(®) is effective and well tolerated in daily clinical practice.

Associations between trait anxiety and psychopathological characteristics of children at high risk for severe antisocial development

It is thought that among children at a high risk for antisocial personality disorder, the level of individual anxiety might constitute an important marker with respect to symptomatology and prognosis. The aim of the present study was to examine whether associations between anxiety and subtypes of aggression (proactive and reactive) exist in boys with early-onset subtype of conduct disorder (CD) and co-morbid attention-deficit hyperactivity disorder (ADHD). A detailed psychometric characterization of boys with ADHD and the early-onset subtype of CD (n = 33) compared to healthy controls (n = 33) was performed. The assessment included trait anxiety, internalizing and externalizing problems, symptoms of psychopathy and temperament traits, as well as subtypes of aggressive behavior. Descriptive statistics, correlation analyses, and group comparisons were calculated. The clinical group was characterized by higher levels of externalizing and internalizing symptoms. Individual anxiety was positively associated with harm avoidance, symptoms of oppositional defiant disorder (ODD), and by trend with reactive aggression. In contrast, boys with reduced levels of anxiety exhibited more callous-unemotional traits. Our results indicate that children with the early-onset subtype of CD and ADHD constitute a psychopathological heterogeneous group. The associations between individual levels of trait anxiety, temperament traits, and subtypes of aggressive behavior in children with ADHD and severe antisocial behavior emphasize the impact of anxiety as a potential key factor that might also be crucial for improvement in therapeutic strategies and outcome measures. Anxiety should be considered carefully in children with ADHD and the early-onset subtype of CD in order to optimize current therapeutic interventions.
