ObjectiveThe aim of this study is to perform the first meta-meta-analysis on the effectiveness of parent-based interventions for children with externalizing behavior problems. Even though parent-based interventions are considered as effective treatments the effects reported in meta-analyses are heterogeneous and the implementation in clinical practice is suboptimal. Recapitulative valid effect predictions are required to close the still existing gap between research findings and clinical practice. The meta-meta-analytic results on changes in child behavior shall result in a clear signal for clinical practice.MethodsThis meta-meta-analysis encompasses 26 meta-analyses identified via search in electronic databases (PsycINFO, Medline, PubMed). Meta-analyses had to report effects of parent-based interventions on child behavior and focus on children under the age of 13 years with externalizing behavior problems in a clinical setting. Analyses were based on random-effects models. To combine results, the effect estimates of the meta-analyses were transformed to SMD and weighted to correct for primary study overlap. The meta-meta-analysis is registered on PROSPERO, registration number CRD42016036486 and was conducted in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses statement (PRISMA).ResultsThe results indicate a significant moderate overall effect for child behavior (SMD = 0.46) as well as for parent reports (SMD = 0.51) and observational data (SMD = 0.62). Further analyses focusing on child externalizing behavior yielded significant and moderate effects (SMD = 0.45). All effects remained stable to follow-up. Considerable heterogeneity was observed within results.ConclusionParent-based interventions are shown to be effective in improving behavior in children with externalizing behavior problems, as assessed using parent reports and observational measures. The present results should encourage health care providers to apply evidence-based parent-based interventions.

The Autism Diagnostic Observation Schedule is a semi-structured, standardized assessment tool for individuals with suspected autism spectrum disorders (ASD) and is deemed to be part of the gold standard for diagnostic evaluation. Good diagnostic accuracy and interpersonal objectivity have been demonstrated for the ADOS in research setting. The question arises whether this is also true for daily clinical practice and whether diagnostic accuracy depends on specialized experience in the diagnostic evaluation. The present study explores the diagnostic accuracy of the original and the revised version of the ADOS for Modules 1 through 4. Thus, seven cases of ADOS executions were recorded and coded by a group of experts of specialized outpatient clinics for ASD. In an extensive consensus process, including video analysis of every minute of the ADOS executions, a "gold standard" coding for every case was defined. The videos of the ADOS administration were presented to a large group of clinicians (from daily clinical routine care) and their codings (n = 189) were obtained and analysed. Variance of coding and congruence with the expert coding were determined. High variance was found in the codings. The accuracy of the coding depends on the experience of the coder with the ADOS as well as on characteristics of the cases and the quality of the administration of the ADOS. Specialization in the diagnostic of ASD has to be claimed. Specialized outpatient clinics for ASD are required which guarantee a qualified diagnostic/differential diagnostic and case management with the aim of demand-oriented supply of individual cases.

This is the first meta-meta-analysis examining the effects of parent-based interventions for children with externalizing behavior problems on parental characteristics (parenting, parental perceptions, parental mental health, parental relationship quality). Parent training interventions are recognized as evidence-based interventions for the treatment of externalizing behavior problems, although meta-analytic effects are heterogeneous. The objective of the present study was to comprehensively combine meta-analytic results on parent training interventions to arrive at valid effect predictions. Electronic databases were searched (PsycINFO, Medline, PubMed). In total, 11 meta-analyses were included that mainly comprised parents of children under the age of 13 years. Analyses were based on random effects models. Effect estimates were transformed to standardized mean differences (SMD) and corrected for primary study overlap. Results revealed a significant moderate overall effect for parenting (SMD 0.53) as well as for parents' report of parenting (SMD 0.60) and parental perceptions (SMD 0.52). Effects remained stable to follow-up. Results for observational data, parental mental health and parental relationship quality were small and only partially significant. Considerable heterogeneity within results was revealed. Overall, parent training interventions proved to be effective in improving parental characteristics for parents of children with externalizing behavior problems. Effectiveness was stronger regarding characteristics explicitly targeted by interventions. The findings should encourage health-care providers to apply evidence-based parent training interventions.

The ADHD-symptom clusters matched types that have been proposed in recent models. This description might help to identify different ADHD-related pathways in future longitudinal research.

The results indicate different neuropsychological pathways related to 'positive family history of ADHD' and prenatal risks. Given a cross-validation in future studies, the results underscore the endophenotypic character of IC and DA in preschool ages.
