At present, the most frequently investigated psychosocial intervention for borderline personality disorder (BPD) is dialectical behavior therapy (DBT). We conducted a meta-analysis to examine the efficacy and long-term effectiveness of DBT.
Systematic bibliographic research was undertaken to find relevant literature from online databases (PubMed, P...
Although posttraumatic stress disorder (PTSD) is used as a distinct diagnosis in clinical practice, its symptoms were characterized as a dimensional structure in several taxometric analyses. However, a categorical latent structure of PTSD could be superimposed by using indistinct PTSD symptoms that can appear within the framework of other trauma-in...

Background:
Pro Kind is a German adaptation of the US Nurse Family Partnership program. It is an intervention based on home visits targeting first-time mothers from disadvantaged populations. Pro Kind was implemented as a randomized control trial from 2006 to 2012 with N = 755 first-time mothers (TG n = 394, CG n = 391). The 7–8-year follow-up aims...
Objectives:
Given the lasting positive effects of prenatal and infancy home visiting in the United States on disadvantaged mothers and children at school age, we analyzed the follow-up effects of a German home visiting program (ProKind). We hypothesized improvements in 3 domains at child age 7 years: (1) child development and life satisfaction, (2...
Introduction
The Generalized Anxiety Disorder-7 (GAD-7) scale is widely used to assess generalized anxiety symptoms in both clinical and general populations. However, updated psychometric evaluations and population norms for the German adult population are lacking. This study aims to examine the psychometric properties of the GAD-7 and provide repr...
Importance
Home-based interventions targeting socially disadvantaged families may help to improve maternal and child health. Only a few studies have investigated how different staffing models affect early home visiting program outcomes.
Objective
To assess the effects of 2 staffing models of an early childhood intervention on mother and child outc...
Background
The Patient Health Questionnaire (PHQ-9) is a popular tool for assessing depressive symptoms in both general and clinical populations. The present study used a large representative sample of the German adult population to confirm desired psychometric functioning and to provide updated population norms.
Methods
The following psychometric...
We study the impacts of a prenatal and infancy home visiting program targeting disadvantaged families on mental health outcomes, assessed through diagnostic interviews. The program significantly reduced the prevalence of mental health conditions for both mothers and children, measured at primary-school age, and broke the intergenerational associati...
Background
Rigorous research trials have demonstrated that early childhood interventions can reach socially disadvantaged families and can have a lasting impact on the healthy development of their children. However, little is known about the internal and contextual factors that contribute to the long-term implementation of such interventions. In th...
Recent developments in society, together with an increase in the number of far-right motivated crimes in Germany, suggest that far right-wing attitudes are becoming increasingly popular within public opinion. Since political attitudes are shaped within the family and peer setting during the adolescent stage, assessing the potential interplay of fam...
Despite increasing attention to the study of forgiveness, little consideration has been imparted to the act of forgiving as a religiously shaped path towards relationship satisfaction. This study examines (1) whether a person’s doctrine-shaped trait forgiveness (DTF) is positively associated with relationship satisfaction; and (2) whether two dimen...
The revised Olweus Bullying Questionnaire (OBQ-R) is a frequently used self-report measure that assesses bullying and victimization. This study evaluated the reliability and validity of the German OBQ-R with a representative sample of ninth graders (N = 12,444). Measurement invariance across gender and migration background was analyzed. The two-fac...

The main objective of this study was to examine the psychometric properties of the newly translated German version. Methods: A sample of 1024 participants answered the questionnaire and sever...
Overall, adolescents exhibit a high level of confidence in the police. Nevertheless, it is problematic when certain social groups show lower levels of confidence in the police as this can affect police legitimacy. Based on a representative survey of ninth-grade students in Lower Saxony ( N = 12,444), conducted in 2019, the current study examines co...
Objective:
The literature on alexithymia has multiplied in recent decades as the construct has important implications for mental health. The so far used inventories are of limited use in epidemiological research, primary care, and other clinical settings where time and effort are important factors in assessment. Based on items of the authorized Ge...
Addictive-like eating is prevalent, but a clear conceptualization and operationalization outside of an addiction framework is lacking. By adopting a biopsychological framework of food reward, this study sought to develop and evaluate a brief self-report questionnaire for the trait assessment of hedonic overeating and dyscontrol. Items in the Hedoni...
The focus of the Lower Saxony Survey is the investigation of unreported cases of juvenile delinquency, i.e., experiences of violence, violent offenses, as well as victimhood and perpetration of property crimes. In addition, factors of juvenile delinquency as well as other forms of deviant behavior are collected, including truancy and the consumptio...

A large amount of research has addressed the issue of the latent status of psychiatric disorders and related phenomena. We used a new taxometric approach developed by Ruscio to examine the latent status of callous-unemotional (CU) traits in a large representative study of German ninth graders ( N = 3,878). Rather than estimating a putative taxon ba...
Teen dating violence (TDV) and school violence (SV) are two major social problems in adolescence. Until recently, the antecedents of both TDV and SV have been analyzed largely independently of each other. This study analyses and compares the determinants of both TDV and SV, with a focus on physical violence. Based on a comprehensive survey of ninth...

Background
Home visiting programs constitute an important policy to support vulnerable families with young children. One of their principal aims is to improve infant-parent relationships, so a key measure of their effectiveness is based on observational measures of parent-children interactions. In the present study we provide novel evidence on the...
The Hopkins Symptom Checklist–25 (HSCL-25) is a widely applied measure of depression and anxiety. The present study examines two of its short forms—the HSCL-5 and HSCL-10, which have been proposed by previous research—in a representative sample of the German general population. To this end, we conducted exploratory and confirmatory analysis on two...

We also present associations between TDV involvement and psychosocial functioning of adolescents (somatic...
Introduction:
Individuals suffering from overweight or obesity frequently experience weight-based stigmatization. The widespread belief that weight is a matter of personal will and self-control results in various weight-based stereotypes (e.g., laziness, lack of self-discipline, or neglect).
Objective:
Based on the modified version of the Weight...
Die Demokratie in Deutschland steht unter Druck: Soziale und kulturelle Ungleichheit, Fremdenfeindlichkeit und Antisemitismus sowie von vielen Seiten infrage gestellte demokratische Grundwerte machen es notwendig, Vereinigungs- und Integrationsprozesse nach 1989 von Neuem zu beleuchten.
Im Dialog zwischen Theorie und empirischer Analyse vermessen d...
Measurement invariance and normative data of the 8-item short form of the Center of Epidemiological Studies-Depression Scale (CES-D-8)Objectives: Female gender is a risk factor for depression. It is questionable whether a given psychometric instrument depicts depressive symptom severity in men and women alike. Therefore, we examined measurement inv...
The „Center for Epidemiological Studies Depression Scale“ (CES-D; Radloff, 1977) is a questionnaire used world-wide to measure depressive symptoms. Although the original four-factor-structure has been widely accepted and replicated, some studies point to other factor-structures like a one- and two-factor-structure. The goal of the current study was...
The common factor model – by far the most widely used model for factor analysis – assumes equal item intercepts across respondents. Due to idiosyncratic ways of understanding and answering items of a questionnaire, this assumption is often violated, leading to an underestimation of model fit. Maydeu-Olivares and Coffman (2006) suggested the introdu...
Obgleich angesichts steigender Ausstattungsquoten Jugendlicher mit digitalen Medien davon ausgegangen werden kann, dass die Prävalenzraten für das Phänomen Cybermobbing (CM) steigen, liegen bisher kaum belastbare Prävalenzschätzungen und Zeitreihen für Deutschland vor.

Impact of Intimate Partner Violence on Child's Cognitive Development - Results from the Evaluation of the Home Visiting Program "Pro Kind" Intimate partner violence (IVP) is a socially relevant problem area of high prevalence. Direct or indirect IVP leads to well documented problems in child socioemotional development. Longitudinal studies on influ...
Research has shown that childhood victimization is associated with later involvement in delinquency. Prevalence rates of childhood victimization also tend to be higher among prison inmates compared with the general population. However, it has rarely been examined if childhood experiences—both negative and positive—have an effect on prison misconduc...
Early mental and behavioral disorders are significant predictors of psychopathologies in adulthood. Parenting behavior (e.g., overreactivity and laxness) influences the development of behavioral problems in children. It is thus often assessed in therapeutic settings, as well as in the context of intervention studies. The aim of this study was to de...
The enduring impact of perceived parental behavior on self-esteem as well as anxiety and depression in adults is still unknown. In a large random route sample (age range 18–92), 4,747 subjects were asked to complete questionnaires about recalled parental rearing, selfesteem, anxiety, and depression. Structural equation modeling was used, and the da...
Previous research has repeatedly shown that gender-based violence affects a considerable proportion of women in any given population. Apart from providing current estimates of the prevalence of sexual violence against women in Germany, we identified specific risk markers applying an advanced statistical method. We analyzed data from a survey of N =...
The Theory of Mind (ToM) competency is closely related to the child’s cognitive, language, and socio-emotional development.
