Screening for affective dysregulation in school-aged children: relationship with comprehensive measures of affective dysregulation and related mental disorders

Affective dysregulation (AD) is characterized by irritability, severe temper outbursts, anger, and unpredictable mood swings, and is typically classified as a transdiagnostic entity. A reliable and valid measure is needed to adequately identify children at risk of AD. This study sought to validate a parent-rated screening questionnaire, which is part of the comprehensive Diagnostic Tool for Affective Dysregulation in Children (DADYS-Screen), by analyzing relationships with comprehensive measures of AD and related mental disorders in a community sample of children with and without AD. The sample comprised 1114 children aged 8-12 years and their parents. We used clinical, parent, and child ratings for our analyses. Across all raters, the DADYS-Screen showed large correlations with comprehensive measures of AD. As expected, correlations were stronger for measures of externalizing symptoms than for measures of internalizing symptoms. Moreover, we found negative associations with emotion regulation strategies and health-related quality of life. In receiver operating characteristic (ROC) analyses, the DADYS-Screen adequately identified children with AD and provided an optimal cut-off. We conclude that the DADYS-Screen appears to be a reliable and valid measure to identify school-aged children at risk of AD.

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.

Validation of a new emotion regulation self-report questionnaire for children

OBJECTIVE

To examine and validate the self-report Questionnaire on the Regulation of Unpleasant Moods in Children (FRUST), which is a modified and shortened version of the Questionnaire for the Assessment of Emotion Regulation in Children and Adolescents (FEEL-KJ).

METHODS

The data comprised child and parent ratings of a community-screened sample with differing levels of affective dysregulation (AD) (N = 391, age: M = 10.64, SD = 1.33, 56% male). We conducted latent factor analyses to establish a factor structure. Subsequently, we assessed measurement invariance (MI) regarding age, gender, and AD level and evaluated the internal consistencies of the scales. Finally, we examined the convergent and divergent validity of the instrument by calculating differential correlations between the emotion regulation strategy (ERS) scales and self- and parent-report measures of psychopathology.

RESULTS

A four-factor model, with one factor representing Dysfunctional Strategies and the three factors Distraction, Problem-Solving and Social Support representing functional strategies provided the best fit to our data and was straightforward to interpret. We found strong MI for age and gender and weak MI for AD level. Differential correlations with child and parent ratings of measures of psychopathology supported the construct validity of the factors.

CONCLUSIONS

We established a reliable and valid self-report measure for the assessment of ERS in children. Due to the reduced number of items and the inclusion of highly specific regulatory behaviors, the FRUST might be a valuable contribution to the assessment of ER strategies for diagnostic, therapeutic, and research purposes.

Child-therapist and parent-therapist alliances and outcome in the treatment of children with oppositional defiant/conduct disorder

OBJECTIVE

This study examined the quality of therapeutic alliance from different rater perspectives (child, parent, therapist) in cognitive behavioural therapy for children with oppositional defiant disorder (ODD) and conduct disorder (CD), and its association with symptom severity. Further, a panel model with an autoregressive cross-lagged panel design was used to explore whether therapist-rated and parent-rated therapeutic alliance influences change in symptom severity, or vice versa.

METHODS

Sixty boys aged 6-12 years with a principal diagnosis of ODD/CD, and their parents, received individually delivered social competence training for childhood aggressive behaviour problems. Child, therapist, and parent ratings of therapeutic alliance and symptom severity were measured twice.

RESULTS

Our results indicate good to very good therapeutic alliance that was relatively stable over time. The cross-sectional analyses of the alliance-symptom association revealed moderate correlations. However, effects of early alliance on later treatment outcome or of early symptom severity on later alliance were marginal. The only significant association was found between early parent-rated therapist-parent alliance and later parent-rated symptom severity.

CONCLUSION

Our study shows a moderate correlation between simultaneously assessed therapeutic alliance and symptoms. The findings of the panel model indicate that an early good therapeutic alliance is a component of later therapeutic success (parent perspective).

Effects of a smartphone app-augmented treatment for children with oppositional defiant disorder / conduct disorder and peer-related aggressive behavior - a pilot study

Background

Social competence training interventions, especially child-focused ones, have proven to be effective in the treatment of children with conduct disorder. Therapy homework assignments implemented between the therapy sessions are essential for practicing strategies developed during treatment sessions and transferring them to everyday life. However, clinical experience shows that patients’ adherence regarding these assignments is often low, thus diminishing the treatment success. One obstacle in this regard is a lack of motivation. The use of smartphone apps in the context of child and adolescent psychotherapy is relatively new, and may provide novel ways to improve the transfer of coping strategies to daily life between treatment sessions. However, only a small number of high-quality studies have analyzed the systematic use of smartphone apps in therapy. The present study will therefore evaluate patients’ homework assignment adherence when using a smartphone app as compared to a paper-and-pencil method.

Method

The study will be conducted as a randomized controlled trial to evaluate the impact of a smartphone app on the adherence to therapy homework assignments (n = 35) in the treatment of children with aggressive behavior aged 6–12 years compared to paper-and-pencil homework assignments (n = 35).

Discussion

This trial is intended as a pilot study and aims to provide a basis for a subsequent multicenter trial. However, the results may already lead to recommendations for the development and use of mental health-related smartphone apps for children and adolescents with aggressive behavior problems.

The DADYS-Screen: Development and Evaluation of a Screening Tool for Affective Dysregulation in Children

Affective dysregulation (AD) in children is characterized by persistent irritability and severe temper outbursts. This study developed and evaluated a screening questionnaire for AD in children. The development included the generation of an initial item pool from existing instruments, a Delphi rating of experts, focus groups with experts and parents, and psychometric analyses of clinical and population-based samples. Based on data of a large community-based study, the final screening questionnaire was developed (n = 771; 49.7 % female; age M = 10.02 years; SD = 1.34) and evaluated (n = 8,974; 48.7 % female; age M = 10.00 years; SD = 1.38) with methods from classical test theory and item response theory. The developed DADYS-Screen (Diagnostic Tool for Affective Dysregulation in Children-Screening Questionnaire) includes 12 items with good psychometric properties and scale characteristics including a good fit to a one-factorial model in comparison to the baseline model, although only a "mediocre" fit according to the root mean square error of approximation (RMSEA). Results could be confirmed using a second and larger data set. Overall, the DADYS-Screen is able to identify children with AD, although it needs further investigation using clinical data.

Assessing anger and irritability in children: psychometric evaluation and normative data for the German version of the PROMIS® Parent Proxy Anger Scale

Purpose

Anger and irritability are common and impairing symptoms in children. The PROMIS Anger scales assess self- and parent-reported irritable and angry mood over the past 7 days. The aim of this study was to evaluate the psychometric properties of the German version of the PROMIS Parent Proxy Short Form v1.0—Anger and to provide normative data.

Methods

To evaluate the psychometric properties, data from the study ADOPT Epidemiology were used. In this study, the PROMIS Anger Scale was administered to a population-based sample of n = 8746 parents of children aged 8–12 years. Psychometric analyses were carried out including the investigation of distribution characteristics, factor structure, model fit, internal consistency, and congruent validity. Normative data were calculated as percentile ranks and T-scores.

Results

The PROMIS Anger Scale demonstrated good psychometric properties, including satisfactory distribution characteristics, unidimensionality, good internal consistency as well as congruent validity. German normative data for the PROMIS Anger Scale are presented.

Conclusion

Based on first psychometric analyses, the German version of the PROMIS Anger Scale can be recommended for use in research and practice; however, further investigations using clinical data are needed. The normative data will allow researchers and clinicians an interpretation of the test scores in future applications.

Disentangling symptoms of externalizing disorders in children using multiple measures and informants

The trait impulsivity theory suggests that a single, highly heritable externalizing liability factor, expressed as temperamental trait impulsivity, represents the core vulnerability for externalizing disorders. The present study sought to test the application of latent factor models derived from this theory to a clinical sample of children. Participants were 474 German children (age 6-12 years, 81% male) with symptoms of attention-deficit/hyperactivity disorder and externalizing behavior problems participating in an ongoing multicenter intervention study. Using confirmatory factor analyses (CFA) and exploratory structural equation modeling (ESEM), we evaluated several factor models of externalizing spectrum disorders (unidimensional; first-order correlated factors; higher-order factor; fully symmetrical bifactor; bifactor S-1 model). Furthermore, we assessed our prevailing factor models for measurement invariance across raters (clinicians, parents, teachers) and assessment modes (interview, questionnaires). While both CFA and ESEM approaches provided valuable insights into the multidimensionality, ESEM solutions were generally superior since they showed a substantially better model fit and less biased factor loadings. Among the models tested, the bifactor S-1 CFA/ESEM models, with a general hyperactivity-impulsivity reference factor, displayed a statistically sound factor structure and allowed for straightforward interpretability. Furthermore, these models showed the same organization of factors and loading patterns, but not equivalent item thresholds across raters and assessment modes, highlighting cross-situational variability in child behavior. Our findings are consistent with the assumption of the trait impulsivity theory that a common trait, presented as hyperactivity-impulsivity symptoms, underlies all externalizing disorders.

Dimensions of Autistic Traits Rated by Parents of Children and Adolescents with Suspected Autism Spectrum Disorders

To examine the factor structure of autism spectrum disorder (ASD) and the psychometric properties of the German Symptom Checklist for Autism Spectrum Disorders (SCL-ASD). Data were collected from 312 clinical referrals with suspected ASD (2–18 years). Confirmatory factor analyses and analyses of reliability, convergent and divergent validity were performed. A bifactor model with one general ASD factor and two specific factors (interaction-communication; restricted, repetitive behaviors) provided an adequate data fit. Internal consistencies of the SCL-ASD subscales and the total scale were > .70. Correlations with measures of ASD traits were higher than correlations with measures of externalizing and internalizing symptoms. The results support a factor structure consistent with DSM-5/ICD-11 criteria. The SCL-ASD has sound psychometric properties.

Toward a Dimensional Assessment of Externalizing Disorders in Children: Reliability and Validity of a Semi-Structured Parent Interview

OBJECTIVE

This study assesses the reliability and validity of the DSM-5-based, semi-structured Clinical Parent Interview for Externalizing Disorders in Children and Adolescents (ILF-EXTERNAL).

METHOD

Participant data were drawn from the ongoing ESCAschool intervention study. The ILF-EXTERNAL was evaluated in a clinical sample of 474 children and adolescents (aged 6-12 years, 92 females) with symptoms of attention-deficit/hyperactivity disorder (ADHD). To obtain interrater reliability, the one-way random-effects, absolute agreement models of the intraclass correlation (ICC) for single ICC(1,1) and average measurements ICC(1,3) were computed between the interviewers and two independent raters for 45 randomly selected interviews involving ten interviewers. Overall agreement on DSM-5 diagnoses was assessed using Fleiss' kappa. Further analyses evaluated internal consistencies, item-total correlations as well as correlations between symptom severity and the degree of functional impairment. Additionally, parents completed the German version of the Child Behavior Checklist (CBCL) and two DSM-5-based parent questionnaires for the assessment of ADHD symptoms and symptoms of disruptive behavior disorders (FBB-ADHS; FBB-SSV), which were used to evaluate convergent and divergent validity.

RESULTS

ICC coefficients demonstrated very good to excellent interrater reliability on the item and scale level of the ILF-EXTERNAL [scale level: ICC(1,1) = 0.83-0.95; ICC(1,3) = 0.94-0.98]. Overall kappa agreement on DSM-5 diagnoses was substantial to almost perfect for most disorders (0.38 ≤ κ ≤ 0.94). With some exceptions, internal consistencies (0.60 ≤ α ≤ 0.86) and item-total correlations (0.21 ≤ r it ≤ 0.71) were generally satisfactory to good. Furthermore, higher symptom severity was associated with a higher degree of functional impairment. The evaluation of convergent validity revealed positive results regarding clinical judgment and parent ratings (FBB-ADHS; FBB-SSV). Correlations between the ILF-EXTERNAL scales and the CBCL Externalizing Problems were moderate to high. Finally, the ILF-EXTERNAL scales were significantly more strongly associated with the CBCL Externalizing Problems than with the Internalizing Problems, indicating divergent validity.

CONCLUSION

In clinically referred, school-age children, the ILF-EXTERNAL demonstrates sound psychometric properties. The ILF-EXTERNAL is a promising clinical interview and contributes to high-quality diagnostics of externalizing disorders in children and adolescents.

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.

[The prevention of externalizing disturbances]

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.

A new treatment for children with chronic tic disorders - Resource activation

The aim of this pilot study is to evaluate the efficacy of a resource activation (RA) program as an alternative intervention for children and adolescents with tic disorders. RA interventions focus on the strengths and abilities of the patients. This is expected to improve the patients' perceptions regarding their own resources, which may indirectly result in a reduction of tic symptoms, impairment and comorbid conditions. A within-subject design with two phases (8 weeks diagnostic; 16 sessions treatment) was analyzed using multilevel modeling (n = 24). During the treatment phase, significant reductions of tics were found in clinical rating (Yale Global Tic Severity Scale; YGTSS), parent rating and video observation (motor tics). Moreover, an improvement was shown on most tic-related impairment and subjective burden (SB) ratings. No significant improvement was found regarding comorbid problems and self-esteem. Compared to the preceding diagnostic phase, a significant incremental treatment effect emerged in clinical rating of tic symptoms (YGTSS) and video observation (motor tics). This pilot study provides first hints that RA may represent an effective treatment for reducing tic symptoms, impairment and SB. However, further research is needed in order to establish RA as an effective treatment for tic disorders.

Child-based treatment of oppositional defiant disorder: mediating effects on parental depression, anxiety and stress

Previous research has shown that child-oppositional defiant disorder (ODD) and conduct disorders (CD) are associated with parental symptoms of depression, anxiety and/or stress, probably in a bidirectional relationship with mutual influences. It is, therefore, reasonable to assume that in child-centered treatment, a decrease in child-oppositional behavior problems constitutes (at least in part) a mechanism of change for a subsequent reduction in parental psychopathology. The aim of the present study (Clinical trials.gov Identifier: NCT01406067) was to examine whether the reduction in ODD symptoms due to child-based cognitive behavioral treatment (CBT) led to a reduction in parental depression, anxiety and stress. Eighty-one boys (age 6-12 years) with a diagnosis of ODD/CD were randomized either to a cognitive behavioral intervention group or an educational play group (acting as control group). Mediation analyses were conducted using path analysis. The stronger reduction in child ODD symptoms in the CBT group compared to the control group led to a decrease in parental depression and stress, as indicated by significant indirect effects (ab = 0.07 and ab = 0.08, p < 0.05). The proposed model for mechanisms of change was, therefore, confirmed for two of the three outcome parameters. Parental psychopathology and stress can be modified by child-centered CBT. The preceding reduction in ODD symptoms acts as a mediator for at least some of the changes in parental depression and stress. However, due to some limitations of the study, other possible explanations for the results found cannot be completely ruled out and are, therefore, discussed.

Efficacy of Habit Reversal Training in Children With Chronic Tic Disorders: A Within-Subject Analysis

The aim of this study is to evaluate a cognitive-behavioral treatment for children and adolescents with tic disorder including habit reversal training (HRT) in a sample of children and adolescents (n = 27). Multiple outcome measures were used to assess the effects of the treatment on tic symptoms. In addition, impairment/subjective burden ratings and the self-efficacy to control tics were assessed. A within-subject design with two phases (8 weeks diagnostic; 16 sessions treatment) was analyzed using multilevel modeling (MLM). During the treatment phase, significant improvements in tic symptoms, impairment, and self-efficacy to control tics were found on most outcome measures. Treatment effects were found on the clinical rating of tic symptoms (Yale Global Tic Severity Scale [YGTSS]), the self-efficacy to control tics, and the video-observed motor tic frequency by comparing the improvements during treatment with the course of the outcome measures during the preceding diagnostic phase.

Erfassung störungsaufrechterhaltender Komponenten sozialer Angst bei Kindern und Jugendlichen im Eltern- und Selbsturteil

Zusammenfassung. Theoretischer Hintergrund: Der Fragebogen zur Erfassung störungsaufrechterhaltender Komponenten sozialer Angst bei Kindern und Jugendlichen (FESKA) erhebt kognitive, behaviorale und interaktionelle Komponenten sozialer Angststörungen von Kindern und Jugendlichen zwischen 4 und 14 Jahren. Fragestellung: Der FESKA wird im Eltern- (N = 259) und Selbsturteil (N = 159) an einer kombinierten Feld- und klinischen Stichprobe untersucht. Methode: Überprüft werden faktorielle Validität, Reliabilität und Aspekte divergenter und konvergenter Validität. Ergebnisse: Konfirmatorische Faktorenanalysen bestätigen das zugrundeliegende dreifaktorielle Bedingungsmodell. Interne Konsistenzen der Gesamtskalen und der Komponentenskalen sind zufriedenstellend, ihre Wiederholungszuverlässigkeiten sind für das Selbsturteil bedingt und für das Elternurteil nicht zufriedenstellend. Die Korrelationen der Skalen zwischen den Beurteilern fallen geringer als erwartet aus. Die konvergente Validität kann bestätigt werden. Schlussfolgerungen: Unter Berücksichtigung verschiedener Limitationen bestätigen die Befunde die Verwendung des FESKA in Klinik und Forschung.

Bifactor Models Show a Superior Model Fit: Examination of the Factorial Validity of Parent-Reported and Self-Reported Symptoms of Attention-Deficit/Hyperactivity Disorders in Children and Adolescents

BACKGROUND

Various studies have demonstrated that bifactor models yield better solutions than models with correlated factors. However, the kind of bifactor model that is most appropriate is yet to be examined. The current study is the first to test bifactor models across the full age range (11-18 years) of adolescents using self-reports, and the first to test bifactor models with German subjects and German questionnaires.

SAMPLING AND METHODS

The study sample included children and adolescents aged between 6 and 18 years recruited from a German clinical sample (n = 1,081) and a German community sample (n = 642). To examine the factorial validity, we compared unidimensional, correlated factors and higher-order and bifactor models and further tested a modified incomplete bifactor model for measurement invariance.

RESULTS

Bifactor models displayed superior model fit statistics compared to correlated factor models or second-order models. However, a more parsimonious incomplete bifactor model with only 2 specific factors (inattention and impulsivity) showed a good model fit and a better factor structure than the other bifactor models. Scalar measurement invariance was given in most group comparisons.

CONCLUSION

An incomplete bifactor model would suggest that the specific inattention and impulsivity factors represent entities separable from the general attention-deficit/hyperactivity disorder construct and might, therefore, give way to a new approach to subtyping of children beyond and above attention-deficit/hyperactivity disorder.

Die Erfassung von Ängsten im Urteil von Kindern/Jugendlichen und ihren Eltern

Zusammenfassung. Ziel dieser Arbeit ist die Analyse der psychometrischen Qualität des Fremd- und des Selbstbeurteilungsbogens zur Erfassung von Angst- und Zwangsstörungen (FBB-ANZ/SBB-ANZ) in zwei klinischen Stichproben (n = 182 bzw. n = 130). Ergänzend wurde die Faktorenstruktur der Bögen in zwei Feldstichproben (n = 724 bzw. n = 281) untersucht. Für die Skalen beider Fragebögen ergaben sich größtenteils zufriedenstellende interne Konsistenzen (.59 ≤ α ≤ .93). Exploratorische Hauptachsenanalysen mit Promax-Rotation ergaben stichprobenübergreifend für beide Fragebögen Faktoren, welche die a priori definierten, ICD-10- und DSM-IV-basierten Subskalen weitgehend abbilden. Zwischen den Subskalen innerhalb der Fragebögen zeigten sich geringe bis moderate Interkorrelationen, die für eine gute Abgrenzbarkeit der Skalen sprechen. Es fanden sich größtenteils moderate Beurteilerübereinstimmungen zwischen den korrespondierenden Skalen des Fremd- und Selbstbeurteilungsbogens. Die Ergebnisse weisen darauf hin, dass die Fragebögen überwiegend reliable und valide Instrumente darstellen. Weiterer Untersuchungsbedarf besteht insbesondere hinsichtlich der konvergenten und divergenten Validität der Subskalen.

Alltagswirksamkeit ambulanter Verhaltenstherapie von Kindern und Jugendlichen im Urteil der Eltern in einer universitären Ausbildungsambulanz

Zusammenfassung. Hintergrund: Die Wirksamkeit von kognitiver Verhaltenstherapie bei Kindern und Jugendlichen unter Routinebedingungen ist bislang noch wenig untersucht. Fragestellung: Es wurden Veränderungen psychischer Auffälligkeiten von Kindern und Jugendlichen im Elternurteil während ambulanter Verhaltenstherapie in einer universitären Ausbildungsambulanz untersucht. Die Therapien wurden durchgeführt von Diplom-Psychologen, Pädagogen, Sozialpädagogen und Sozialarbeitern in fortgeschrittener Ausbildung zum Kinder- und Jugendlichenpsychotherapeuten mit Schwerpunkt Verhaltenstherapie. Alle Therapien wurden im Verhältnis 1:4 supervidiert. Methode: Für 976 Therapien wurden Completeranalysen als Prä-Post-Vergleiche mit Effektstärken auf der Child Behavior Checklist (CBCL) berechnet und die klinische Bedeutsamkeit der Veränderungen analysiert–jeweils für die Gesamtgruppe und für die auf der CBCL zu Therapiebeginn klinisch Auffälligen. Zusätzlich wurde die Repräsentativität dieser Analyse für die gesamte Stichprobe überprüft. Ergebnisse: In der Gesamtgruppe fanden sich kleine bis mittlere, in der Gruppe der im Elternurteil auf der CBCL klinisch Auffälligen hauptsächlich große, statistisch signifikante Verminderungen psychischer Auffälligkeiten, die nicht durch Spontanveränderungen oder Regressionseffekte erklärt werden können. Allerdings wurden 1/4 bis 1/3 der Patienten auch nach Therapieende von ihren Eltern weiterhin als klinisch auffällig eingeschätzt. Schlussfolgerungen: Die Ergebnisse weisen auf die Wirksamkeit kognitiv-behavioraler Therapie bei psychisch kranken Kindern und Jugendlichen unter Anwendungsbedingungen hin. Aufgrund der mangelnden experimentellen Kontrolle ist die Aussagekraft der Ergebnisse begrenzt.

Long-term course of ADHD symptoms from childhood to early adulthood in a community sample

Comparatively little information is available from population-based studies on subgroup trajectories of attention-deficit/hyperactivity disorder (ADHD) core symptoms of inattention and hyperactivity-impulsivity (particularly as defined by DSM-IV and ICD-10). Recent report of a subgroup with high and increasing inattention symptoms across development requires replication. To identify the different trajectory subgroups for inattention, hyperactivity-impulsivity and total symptoms of ADHD in children and adolescents aged 7-19 years. Eleven birth cohorts from 2,593 families with children and adolescents who had parent ratings for the outcome measures of inattention, hyperactivity-impulsivity or total symptoms were considered. Data were analysed using an accelerated longitudinal design and growth mixture modelling was applied to detect subgroups. For all three outcome measures, three trajectories with low (78.3-83.3 %), moderate (13.4-18.8 %) and high (2.8-3.2 %) symptom levels were detected. Course within these subgroups was largely comparable across outcome domains. In general, a decrease in symptoms with age was observed in all severity subgroups, although the developmental course was stable for the high subgroups of inattention and total symptoms. About 3 % of children in a community-based sample follow a course with a high level of ADHD symptoms. In this high trajectory group, hyperactivity-impulsivity symptoms decrease with age from 7 to 19 years, whilst inattention and total symptoms are stable. There was no evidence for an increase in symptoms across childhood/adolescence in any of the severity groups.

Psychometric properties of a German parent rating scale for oppositional defiant and conduct disorder (FBB-SSV) in clinical and community samples

The Fremdbeurteilungsbogen für Störungen des Sozialverhaltens (FBB-SSV) is a commonly used DSM- and ICD-based rating scale for disruptive behaviour problems in Germany. This study examined the psychometric properties of the FBB-SSV rated by parents in both a clinical sample (N = 596) and a community sample (N = 720) of children aged 4-17 years. Results indicate that the FBB-SSV is internally consistent (α = .69-.90). Principal component analyses produced two-factor structures that are largely consistent with the distinction between oppositional defiant disorder (ODD) and conduct disorder (CD). Diagnostic accuracy was examined using receiver operating characteristic analyses, which showed that the FBB-SSV is excellent at discriminating children with ODD/CD from those in the community sample (AUC = .91). It has satisfactory diagnostic accuracy for detecting ODD/CD in the clinical sample (AUC = .76). Overall, the results show that the FBB-SSV is a reliable and valid instrument. This finding provides further support for the clinical utility of DSM- and ICD-based rating scales.

An evaluation of the pharmacokinetics of methylphenidate for the treatment of attention-deficit/ hyperactivity disorder

INTRODUCTION

Methylphenidate (MPH) plays a principal role in the multimodal treatment of attention-deficit/hyperactivity disorder (ADHD). Controlled studies have demonstrated an effective reduction in the core symptoms of the disorder following MPH therapy, although long-term studies also demonstrate that the therapeutic benefits dissipate in the absence of combined psychosocial interventions.

AREAS COVERED

This review article focuses on the pharmacological characteristics of MPH, examining its effects on brain metabolism and the neurotransmitter system. Neuropsychological and clinical effects of different immediate and extended release MPH formulations are discussed to aid clinicians in choosing the appropriate formulation. The drug's addictive potency and abuse potential is also discussed. Data came from a literature search of relevant studies performed using the PubMed database up to June 2013.

EXPERT OPINION

MPH is effective in the treatment of the core symptoms of ADHD. Considerable clinical expertise is required to identify an individually well-adapted dosage which will produce the optimal clinical effects with potential side effects minimized. Due to low adherence to medication, especially in adolescents, motivation to treatment and attentive clinical monitoring is mandatory, as is the consideration of risks of abuse or the presence of a comorbid addictive disorder.

Reliability and validity of teacher-rated symptoms of oppositional defiant disorder and conduct disorder in a clinical sample

BACKGROUND/AIMS

It is recommended to use information from multiple informants when making diagnostic decisions concerning oppositional defiant disorder (ODD) and conduct disorder (CD). The purpose of this study was to investigate the reliability and validity of teacher-rated symptoms of ODD and CD in a clinical sample.

METHODS

The sample comprised 421 children (84% boys; 6-17 years) diagnosed with ODD, CD, and/or attention deficit hyperactivity disorder (ADHD). Teachers completed a standardized ODD/CD symptom rating scale and the Teacher Report Form (TRF).

RESULTS

The reliability (internal consistency) of the symptom rating scale was high (α = 0.90). Convergent and divergent validity were demonstrated by substantial correlations with similar TRF syndrome scales and low-to-moderate correlations with dissimilar TRF scales. Discriminant validity was shown by the ability of the symptom rating scale to differentiate between children with ODD/CD and those with ADHD. Factorial validity was demonstrated by principal component analysis, which produced a two-factor solution that is largely consistent with the two-dimensional model of ODD and CD proposed by the Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV-TR, although some CD symptoms representing aggressive behavior loaded on the ODD dimension.

CONCLUSION

These findings suggest that DSM-IV-TR-based teacher rating scales are useful instruments for assessing disruptive behavior problems in children and adolescents.

Erfassung aggressionsauslösender und -aufrechterhaltender Faktoren bei Kindern mit oppositionellen und aggressiven Verhaltensstörungen im Eltern-, Lehrer- und Selbsturteil

Theoretischer Hintergrund: Der Fragebogen zum aggressiven Verhalten von Kindern (FAVK) dient der Erfassung vier möglicher aggressionsauslösender und -aufrechterhaltender Komponenten von Kindern und Jugendlichen zwischen 4 und 14 Jahren. Fragestellung: Der FAVK soll erstmals im Eltern- (n = 156), Lehrer- (n = 104) und Selbsturteil (n = 91) an einer klinischen Stichprobe (6 – 12 Jahre) untersucht werden. Methode: Überprüft werden faktorielle und interne Validität, Reliabilität und Aspekte divergenter und konvergenter Validität. Ergebnisse: Konfirmatorische Faktorenanalysen bestätigen das zugrundeliegende vierfaktorielle Bedingungsmodell und eine in Feldstichproben gefundene dreifaktorielle Struktur. Interne Konsistenzen der Gesamtskalen sind zufriedenstellend (α > .70), ihre Wiederholungszuverlässigkeiten nicht. Die Korrelationen der Skalen zwischen den Beurteilern fallen geringer als erwartet aus. Zumindest im Elternurteil lassen sich die konvergente und divergente Validität bestätigen. Schlussfolgerung: Unter Berücksichtigung verschiedener Limitationen bestätigen die Befunde die Verwendung des FAVK in Klinik und Forschung.

Effectiveness of telephone-assisted parent-administered behavioural family intervention for preschool children with externalizing problem behaviour: a randomized controlled trial

Externalizing problem behaviour is one of the most common childhood disorders. Parent training is an effective treatment for these children and there is growing interest in the effects of parent-administered interventions with minimal therapist contact. This randomized controlled study examined the efficacy of a telephone-assisted parent-administered behavioural intervention (bibliotherapy) in families with preschool children with externalizing problem behaviour. Families were randomly assigned to a treatment group (n = 26) and an untreated waitlist control group (n = 22). The intervention comprised the reading of an 11 chapter self-help book and 11 weekly telephone consultations. Compared to the control group, the treatment group demonstrated significant decreases in parent-reported externalizing and internalizing child problem behaviour and dysfunctional parenting practices. Moreover, treated parents reported less parenting-related strains and decreases in parental depression, anxiety, and stress. The results suggest that telephone-assisted self-administered parent training is an effective alternative to more intensive forms of behavioural family intervention for preschool children with externalizing problem behaviour.

Any indication for bias due to participation? Comparison of the effects of a parent management training rated by participating and non-participating parents

Ratings of parents that have participated in a parent training for child externalizing behaviour problems might be biased (e.g., they may report symptom reduction to reward their own endeavours for attending the training). The potential for bias in parent ratings was investigated in a secondary analysis of an effectiveness study of a parent management training for children (aged 3-10 years) with externalizing behaviour problems under routine care conditions. For the 56 families included in the current analysis, we compared the ratings of training participants (predominately mothers) and training non-participants (predominately fathers). A 3-month waiting period prior to treatment served as the control condition. Outcome measures were attention problems and conduct problems of the children and perceived parental self-efficacy rated by both the mothers and fathers. Child attention problems and conduct problems both decreased significantly during the treatment period for participating and non-participating parents, and the changes in ratings during treatment were of a similar magnitude for participants compared with non-participants. Taking into account the methodological limitations of the current analysis, no indication was found that treatment effects are strongly biased due to participation in the training.

KEY PRACTITIONER MESSAGES

Previous positive findings of mothers' and fathers' ratings on parent management training for children with externalizing problem behaviour have mostly come from parents who also attended the training. For child behavioural problems, the results of the current analysis demonstrate similar perceived changes by parents who did and did not participate in the training. Our findings underscore the relevance and importance of parent ratings for treatment evaluation.

What contributes to patient and parent satisfaction with medication in the treatment of children with ADHD? A report on the development of a new rating scale

Satisfaction with medication is important in the evaluation of overall treatment outcome. There is a lack of consistent and validated rating scales for satisfaction with medication in ADHD, therefore comparison across studies is difficult. Here, we analyse the psychometric properties of the satisfaction with medication scale (SAMS), a new item-based questionnaire that assesses satisfaction with ADHD medication. Furthermore, we evaluate the predictive effect of ADHD symptoms and quality of life (QoL) on satisfaction. Data on satisfaction with Equasym XL(®) (methylphenidate) were collected in the OBSEER study using the parent (SAMS-P, n = 589) and patient (SAMS-S, n = 552) versions of the SAMS questionnaire. Internal consistency, item-total and cross-informant correlations, and the stability of satisfaction ratings over time were assessed. Satisfaction with medication scores were then correlated with ratings of ADHD symptoms and QoL. Rates of overall satisfaction with Equasym XL(®) among parents and children were high (>70%), as was internal consistency for both SAMS-P and SAMS-S (Cronbach's alpha > 0.9). Similarly, item-total correlations were high (r = 0.71-0.90) for SAMS-P and medium-high (r = 0.57-0.77) for SAMS-S. Cross-informant correlations and the stability of satisfaction ratings were moderate (r = 0.54-0.59 and 0.48-0.60, respectively). ADHD symptom and QoL ratings were significantly negative and positive predictors of satisfaction, explaining 36-52% of satisfaction variance at the final visit. The results show that parent and patient satisfaction was high and could be assessed reliably with the new SAMS questionnaire. Parent and patient ratings were moderately correlated, and symptom severity, functional impairment and QoL were the most significant predictors of satisfaction.

Assessment of daily profiles of ADHD and ODD symptoms, and symptomatology related to ADHD medication, by parent and teacher ratings

DAYAS is a new two-part rating scale that assesses: (1) ADHD and ODD symptoms (externalising symptom ratings) and (2) symptomatology potentially related to ADHD medication (potentially medication-related symptoms) in real-world settings at different time periods throughout a normal school day. Data from a proof-of-concept study and two observational trials (Medikinet(®) retard [methylphenidate] and the Equasym XL(®) [methylphenidate] OBSEER study) evaluated: (1) validity of weekly externalising symptom ratings using DAYAS, in place of daily ratings; (2) reliability and internal consistency of DAYAS ratings for externalising symptoms and potentially medication-related symptoms; and (3) convergent and divergent validity of the externalising symptom ratings with existing validated scales. From the proof-of-concept study, daily scores by period of day and during the whole day correlated strongly with equivalent weekly scores (r = 0.83-0.92). Internal consistency of externalising symptom rating scales calculated from pooled data were acceptable or good by period of day (Cronbach's alpha = 0.68-0.90) and very high for whole day scores (Cronbach's alpha = 0.88-0.95). Internal consistency of the rating scale for potentially medication-related symptoms was also good for both teacher and parent ratings. From OBSEER data, correlations between FBB-ADHD total symptom scores and ratings on both parent and teacher versions of DAYAS were high (r = 0.73 and r = 0.84, respectively). Correlations between DAYAS and SDQ were highest for the SDQ subscales hyperactivity and conduct problems and substantially lower for pro-social behaviour, peers and emotional problems. The DAYAS rating scale had good internal consistency, and DAYAS scores correlated well with existing validated scales and the SDQ subscales hyperactivity and conduct problems. Weekly DAYAS scores (whole day and by period of day) could be considered a suitable replacement for daily assessment scores.

Aufmerksamkeitsdefizit-/Hyper- aktivitätsstörungen von Kindern und Jugendlichen im Elternurteil

Fragestellung: Der Fremdbeurteilungsbogen für Aufmerksamkeitsdefizit-/Hyperaktivitätsstörung (FBB-ADHS) ist Bestandteil des Diagnostik-Systems für psychische Störungen im Kindes- und Jugendalter nach ICD-10 und DSM-IV (DISYPS-II). Er erfasst in 20 Items die Symptomkriterien nach ICD-10 und DSM-IV und enthält zusätzlich 6 Kompetenzitems. Die vorliegende Studie untersucht in einer repräsentativen Stichprobe auf der Basis der Elternurteile Symptom- und Diagnoseprävalenzen, Reliabilität und faktorielle Validität, Korrelationen mit anderen Auffälligkeiten, Komorbiditätsraten sowie Alters- und Geschlechtseffekte. Methodik: Der Fragebogen wurde in einer per Zufall ausgewählten Feldstichprobe von N = 713 Eltern von Kindern und Jugendlichen im Alter von 4;0 bis 17;11 Jahren beantwortet. Ergebnisse: Laut Elternurteil schwanken die Symptomprävalenzen zwischen 4.5 % und 22.3 %. Die Diagnoseprävalenzen auf der Basis der Symptomkriterien nach DSM-IV liegen bei 11.5 %; nach ICD-10 bei 3.4 %. Bei Berücksichtigung von Funktionseinschränkungen sinken die Prävalenzraten auf 7.9 % bzw. 3.0 %. Die Reliabilitäten der Subskalen sind zufrieden stellend bis sehr gut. In den exploratorischen Faktorenanalysen ließ sich sowohl die Einteilung nach DSM-IV (Unaufmerksamkeit versus Impulsivität/Hyperaktivität) als auch die Aufteilung nach ICD-10 mit drei Faktoren (Hyperaktivität, Impulsivität und Unaufmerksamkeit) replizieren. Signifikante Alters-/Geschlechtseffekte zeigen sich auf den meisten Skalen. Zu den Elternurteilen über Störungen des Sozialverhaltens, Angst- und depressive Störungen fanden sich mittlere Korrelationen und Komorbiditätsraten zwischen 7 % und 39 %. Schlussfolgerungen: Die ermittelten Prävalenzraten entsprechen den Ergebnissen internationaler Studien. Der FBB-ADHS ist als Elternfragebogen ein intern konsistentes und valides Verfahren. Mit der Vorlage von Normen kann er in der Praxis gut eingesetzt werden.
