Thus, the current study aimed to investigate parents’ wishes regarding the support of their children with ADHD in schools. The final sample consisted of n=441 parents of children with ADHD. Themes were i...

Background: Suicidal ideation represents a major concern in clinical practice. Yet, little is known about the effects of routine psychotherapy on the amelioration of suicidal ideation. Therefore, the aim of the current study is to assess mental disorder-specific changes of suicidal ideation in a large sample of adult outpatients undergoing routine-...

Background Children of parents with a mental illness (COPMI) have multiple psychological and developmental risks, including an increased lifetime risk of developing a mental illness themselves. Emotion regulation (ER) has been identified as a potential underlying mechanism of the transgenerational transmission of mental disorders. This study compar...

Introduction and objective Mental Health Literacy (MHL) is important in promoting youth mental health. One key aspect of MHL is knowledge about mental disorders, which is particularly relevant for populations at risk for developing mental disorders, such as children of parents with a mental illness (COPMI), representing a mechanism within the trans...

Despite a significant accumulation of research, there has been little systemic implementation of evidence-based practices (EBP) in youth mental health care. The fragmentation of the evidence base complicates implementation efforts. In light of this challenge, we sought to pilot a system that consolidates and coordinates the entire evidence base in...

After investigating differences in job insecurity and recovery experience between mentally...

Studies using observational measures often fail to meet statistical standards for both reliability and validity. The present study examined the psychometric properties of the Coding Interactive Behavior (CIB) System within a German sample of parent–child dyads. The sample consisted of 149 parents with and without a mental illness and their children...

Objective Although empathy is known to be a strength, recent studies suggest that empathy can be a risk factor for psychopathology under certain conditions in children. This study examines parental mental illness as such a condition. Further, it aims to investigate whether maladaptive emotion regulation (ER) mediates the relationship between empath...

Children whose parents have a mental illness are much more likely to experience mental health problems and other adverse long-term impacts. Child-centred psychosocial interventions can be effective, but not much is known about how to design and implement them in different settings. A pre-post, mixed methods, single-arm evaluation of a co-designed s...

Although psychological treatments are broadly recognized as evidence-based interventions for various mental disorders, challenges remain. For example, a substantial proportion of patients receiving such treatments do not fully recover, and many obstacles hinder the dissemination, implementation, and training of psychological treatments. These probl...

Patient and public involvement (PPI) is an essential ethical component in mental health research, and represents a major opportunity to improve translational mental health research. The goals of this review were to (1) provide a comprehensive overview of empirical research focusing on PPI of children and young people (CYP) in mental health research...

Objective Children of parents with a mental illness are at heightened risk to develop a mental illness themselves due to genetics and environmental factors. Although parenting stress (PS) is known to be associated with increased psychopathology in parents and children, there is no study investigating PS multimodally in a sample of parents with a me...

Zahlreiche Studien belegen, dass die Arbeit einen erheblichen Einfluss auf die eigene körperliche und psychische Gesundheit hat. Auch konnte wiederholend gezeigt werden, dass sich die Arbeitsbelastung auf weitere Lebensbereiche (wie Beziehung, Familie und Freizeit) auswirken kann (spillover) und sich die negativen Konsequenzen der Arbeitsbelastung...

Expectation violations occur when there is a discrepancy between expected and perceived events or experiences. Often, however, expectations persist despite disconfirming evidence. Therefore, research on expectation violations, expectation change, and expectation persistence has been conducted in several fields of psychology with wide-ranging theore...

As a multidimensional and universal stressor, the COVID-19 pandemic negatively affected the mental health of children, adolescents, and adults worldwide. In particular, families faced numerous restrictions and challenges. From the literature, it is well known that parental mental health problems and child mental health outcomes are associated. Henc...

There are several meta-analyses of treatment effects for children and adolescents with attention deficit hyperactivity disorder (ADHD). The conclusions of these meta-analyses vary considerably. Our aim was to synthesize the latest evidence of the effectiveness of psychological, pharmacological treatment options and their combination in a systematic...

Avoidance-based emotion regulation plays a central role in the development and maintenance of anxiety disorders across the life span. However, measures for children that account for different avoidance strategies, are scarce. Derived from Gross’ Process Model of Emotion Regulation, the Bochum Assessment of Avoidance-based Emotion Regulation for Chi...

Background One of the COVID-19 pandemic consequences that has affected families the most is school lockdowns. Some studies have shown that distance learning has been especially challenging for families with a child with neurodevelopmental disorders such as ADHD or ASD. However, previous studies have not taken the heterogeneity of these disorders in...

Today, there is wide recognition of schools as places that should foster children’s learning and well-being alike. The past two decades have thus witnessed an upsurge in research on children’s subjective well-being (SWB) in school and how it relates to their academic achievement. The first meta-analysis on the SWB/achievement relation revealed subs...

Objective The nature of adverse effects of parental mental health problems and of the interventions to address them may require specific designs of economic evaluation studies. However, methodological guidance is lacking. We aim to understand the broad spectrum of adverse effects from parental mental health problems in children and the economic con...

Durchschnittlich sind ein bis zwei Schüler*innen pro Schulklasse von der Aufmerksamkeitsdefizit-/Hyperaktivitätsstörung (ADHS) betroffen.

Stigma can have devastating health and wellbeing impacts, not just on people with mental health problems, but on people associated with the stigmatized person. This is called stigma-by-association. Children whose parents have mental health problems are a particularly vulnerable group, and stigma acts as a mechanism, contributing to the transgenerat...

Background High Expressed Emotion (HEE) has been identified as a risk factor for the exacerbation and course of mental illness. EE has been investigated as a caregiver's response to an offspring's problem behavior and pathology. The present meta-analysis regards EE from a transgenerational perspective and as one mechanism that might explain the tra...

Metacognitive beliefs have repeatedly proven to play a role in anxiety disorders in children and adolescents, but few studies have investigated whether they change after cognitive behavioral therapy. This longitudinal intervention study explores whether positive and negative metacognitive beliefs in particular change after exposure-focused treatmen...

The COVID-19 pandemic is one of the most serious health and economic crises of the 21st century. From a psychological point of view, the COVID-19 pandemic and its consequences can be conceptualized as a multidimensional and potentially toxic stressor for mental health in the general population. This selective literature review provides an overview...

The current study examined whether a path model including variables influencing the use of effective CMS develope...

In treating childhood anxiety disorders, therapists use highly individualized anxiety hierarchies to assess anxiety-eliciting situations and to personalize treatment. In contrast, psychometric assessment of anxiety symptoms in children usually consists of standardized questionnaires, assessing either total anxiety or disorder-specific symptom score...

Background Regarding the controversy about the overdiagnosis of Attention Deficit/Hyperactivity Disorder (ADHD) in children and adolescents there are two main directions addressed as issue of age bias and issue of gender bias. In this relation, replication of findings demonstrating significant overdiagnosis is of importance which make the systemati...

Current debate has identified the factors emotion knowledge (EK) and attention as specific trajectories longitudinally influencing psychopathological development in childhood. The “Emotion Knowledge Hypothesis” assumes that children with great emotion skills have high self-regulating abilities that result in lower cognitive load and stronger attent...

Children with attention deficit hyperactivity disorder (ADHD) require increased caregiver assistance and supervision, and their parents have shown high perceived parenting stress. Hence, physiological adjustment processes in the caregivers, involving the hypothalamic-pituitary-adrenal axis, seem plausible. We analyzed the association between matern...

Wir bestimmten daher objektive Indikatoren für die Mitwirkung der deutschsprachigen Klinischen Psychologie und ihrer psychologischen Nachba...

Although an average of one to two children per classroom suffer from ADHD, empirically supported classroom interventions are not yet implemented possibly because of teachers’ lack of knowledge or negative attitude towards them. To investigate this science-practitioner gap, we need an instrument assessing knowledge, attitude and the use of ADHD-rela...

A positive attitude of teachers and psychotherapists towards children with ADHD can both support their mutual relationship and support reducing ADHD-related symptoms. According to Fishbein and Ajzen’s rational-choice approach, attitude formation is based on a person’s expectations and the appraisal of these, thus attitude, therefore, differs indivi...

Abstract A reliable diagnosis of adult Attention Deficit/Hyperactivity Disorder (ADHD) is challenging as many of the symptoms of ADHD resemble symptoms of other disorders.
