This study examined whether grandparental support is a protective factor for children's socio‐emotional development in the context of adversity. Using longitudinal data from the Millennium Cohort Study, we investigated the effects of grandparental support across development in children with and without adverse childhood experiences (ACEs). Socio‐em...

Support from grandparents plays a role in mothers' perinatal mental health. However, previous research on maternal mental health has mainly focused on influences of partner support or general social support and neglected the roles of grandparents. In this narrative review and meta-analysis, the scientific evidence on the association between grandpa...

Neurobiological models propose that reactive aggression is predicated on impairments in amygdala-prefrontal connectivity that subserves moral decision-making and emotion regulation. The amygdala is a key component within this neural network that modulates reactive aggression. We provide a review of amygdala dysfunctional brain networks leading to r...

Parental protection is an important, yet understudied aspect of parenting behavior. Predictors of the quality of protection and potential underlying neural mechanisms are still unknown. In this study, we examined whether negative caregiving experiences in fathers’ own childhood are related to protective behavior and neural reactivity to infant thre...

Child maltreatment can negatively impact not only survivors but also survivors’ children. However, research on the intergenerational effect of maternal childhood maltreatment on child externalizing behaviour has yielded contradictory results and has not yet been systematically synthesised. The current three-level meta-analysis and systematic review...

Background The tendencies to interpret social situations as threatening or hostile are called interpretation biases triggering fear or anger, avoidance or aggression, respectively. These biases play a substantial role in internalizing and externalizing problems, but the relationship is not always clear-cut. By measuring different biases in the same...

Adolescents and their families should receive the appropriate support at the right time, based on their strengths, risk factors and needs. However, comprehensive instruments to determine these characteristics seem generally lacking. In the current study we aim to develop a family triage instrument, assessing the necessary level and type of care. Th...

Validly measuring aggression is challenging because self-reports are plagued with biased answer tendencies and behavioral measures with ethical concerns and low ecological validity. The current study, therefore, introduces a novel virtual reality (VR) aggression assessment tool, differentially assessing reactive and proactive aggression. Two VR tas...

Purpose. Support from grandparents plays a role in mothers’ perinatal mental health. However, previous research on maternal mental health mainly focused on influences of partner support or general social support and neglected the roles of grandparents. In this narrative review and meta-analysis, the scientific evidence on the association between gr...

New fathers may grow into their parental role through active involvement in childcare. Spending time in physical contact with the child may promote an adaptive transition to fatherhood. In this randomized controlled trial, we tested the effects of a baby carrier intervention on fathers’ hormonal and neural functioning. Using functional magnetic res...

Previous research has described diverse biological correlates of the psychopathic personality. Efforts to understand the underpinnings of low fear responses in psychopathic individuals have drawn attention to the possible role of abnormalities in hypothalamic-pituitary-adrenal (HPA) axis function, but studies to date have been largely limited to yo...

Alterations in neurobiological stress systems such as the autonomic nervous system (ANS) and hypothalamic-pituitary-adrenal (HPA) axis contribute to the development and maintenance of psychological and behavioral problems after traumatic experiences. Investigating neurobiological parameters and how these relate to each other may provide insight int...

During the Covid-19 pandemic, the governments are trying to contain the spread with non-pharmaceutical interventions (NPIs), such as social distancing rules, restrictions, and lockdowns. In an effort to identify factors that may influence population adherence to NPIs, we examined the role of optimism bias, anxiety, and perceived severity of the sit...

Research has indicated that the majority of infants and toddlers prefer prosocial to antisocial agents, but little research has examined interindividual differences in children's preference. This study examined whether 24-month-olds' (n = 107) sociomoral preference was associated with attachment security or empathy, assessed with the Attachment Q-S...

In the midst of the Covid-19 pandemic, the governments are trying to contain the spread with non-pharmaceutical interventions (NPIs), such as social distancing rules, restrictions, and lockdowns. In an effort to identify factors that may influence population adherence to NPIs, we examined the role of optimism bias, anxiety, and perceived severity o...

Although oxytocin administration influences behavior, its effects on peripheral oxytocin concentrations are mixed and derived from studies on healthy subjects. Additionally, trauma attenuates the behavioral effects of oxytocin, but it is unknown whether it also influences its effect on peripheral circulation. This study examined whether salivary ox...

Neurobiological models propose reactive aggression as a failure in emotion regulation, caused by an imbalance between prefrontal cortical control and excessive bottom-up signals of negative affect by limbic regions, including the amygdala. Therefore, we hypothesize a negative correlation between PFC and amygdala activity (pre/post resting-state sca...

Previous research has revealed a positive effect of oxytocin administration on several social behaviors especially in individuals with social-affective deficits. However, it is still unknown whether intranasal oxytocin administration (OT-IN) can be beneficial to residential youth who exhibit severe social-affective impairments. We conducted a rando...

Although dissociative symptoms are observed in several psychiatric disorders and linked to antisocial behavior and offending, the relation between dissociation and psychopathology or comorbidity has not been consistently investigated in residential youth yet. This brief report documented prevalence and comorbidity rates of several psychiatric disor...

The current study aims to investigate if venting anger reduces or increases aggression. Therefore, we allowed venting anger and measured its effect on aggression after two different anger provocation paradigms in a sample of forensic psychiatric offenders (FPO, N = 45) and penitentiary offenders (PO, N = 22). These provocation paradigms included an...

Although the oxytocin receptor gene (OXTR) is involved in aggression and social affiliation, it has not been examined in gene-environment interaction studies. This longitudinal study examined the effect of genetic variants in OXTR and its gene-environment interaction with perceived deviant peer affiliation in the trajectories of antisocial behavior...

Inconsistent findings have been found on the relation between oxytocin levels and psychopathy or callous-unemotional (CU) traits in humans, potentially because the role of trauma in oxytocin secretion and the distinction between primary and secondary psychopathy have been overlooked so far. Primary psychopathy has a stronger biological background,...

This study aimed at examining cognitive predictors of reactive and proactive aggression in a forensic-psychiatric (n=80) and a non-clinical sample (n=98; Brugman et al., 2015). Three different cognitive predictors were incorporated: (1) attentional bias towards aggressive stimuli (measured with Emotional Stroop task) and towards angry faces (measur...

Objective: Psychopathy is a personality disorder typified by lack of empathy and impulsive antisocial behavior. Psychopathic traits may partly relate to disrupted connections between brain regions. The aim of the present study was to link abnormalities in microstructural integrity of white-matter tracts to the severity of different psychopathic tr...

Callous-unemotional (CU) traits are thought to characterize children exhibiting persistent and severe conduct problems (CPs). Reward and punishment sensitivity have often been investigated, yet executive function problems have mostly been studied in adults. Moreover, the level of co-occurring CPs is important to take into account. Therefore, the cu...

Although numerous studies have examined the neuroendocrinology of aggression, the findings are mixed and focused on cortisol and testosterone. We argue that past findings remain inconclusive partly because the key roles of oxytocin and trauma have not been systematically integrated yet. Oxytocin is associated with social behavior and interacts with...

Anger and anger regulation problems that result in aggressive behaviour pose a serious problem for society. In this study we investigated differences in brain responses during anger provocation or anger engagement, as well as anger regulation or distraction from anger, and compared 16 male violent offenders to 18 non-offender controls. During an fM...

This study examined relationships between the self-conscious emotions of guilt and shame in both clinical (N = 104) and non-clinical (N = 477) (young) adolescents aged 11–18 years, who completed a questionnaire to assess perceived parental rearing behaviors (EMBU-C) and a scenario-based instrument to measure proneness to guilt and shame (SCEMAS). R...

The current study investigated the relationship between psychopathy and two concepts that hold a central position in conceptualizations of this disorder, being guilt and dominance. Both constructs were measured using explicit measures (i.e., self-report), as well as indirect assessment (i.e., the Single Category Implicit Association Test; Sc-IAT)....

The current study investigated whether a multidimensional model could underlie impulsivity and its associations with various disorders in a forensic sample. Data were available from self-report and behavioral impulsivity instruments of 87 forensic patients. Principal component analysis (PCA) was used to derive a dimensional impulsivity model, and t...

Morality deficits have been linked to callous-unemotional traits and externalizing problems in response to moral dilemmas, but these associations are still obscure in response to antisocial acts in adolescence. Limited evidence on young boys suggested that callous-unemotional traits and externalizing problems were associated with affective but not...

Aggression, violence and deviant behavior are terms frequently used interchangeable, but relate to different theoretical concepts. Therefore, this chapter starts with a definition of aggression. Furthermore, several theories regarding the development of aggression will be presented. According to some theories, aggression is biologically or emotiona...

The present study is a replication in Germany of a study originally performed in the Netherlands regarding the association between a positive living group climate and self-reported empathy in incarcerated adolescent male offenders (n = 49). A structural equation model was fitted to the data and showed a relation between a positive living group clim...

Aggression and callous-unemotional (CU) traits are common problems in incarcerated delinquent youth. The present study was conducted to examine whether living group climate was associated with aggression and CU traits in late adolescent male offenders (N = 156) in a German youth prison. A structural equation model was fitted to the data and showed...

This study investigated whether executive dysfunction and impulsivity are both predictors of reactive aggression and is the first to use behavioral assessment of aggression in response to provocation by means of a personalized boxing body opponent bag giving harassing feedback. Aggressive behavior, self-reported aggression, executive functioning (i...

This study tested the predictive value of attentional bias, emotion recognition, automatic associations, and response inhibition, in the assessment of in-clinic violent incidents. Sixty-nine male forensic patients participated and completed an Emotional Stroop to measure attentional bias for threat and aggression, a Single Target – Implicit Associa...

The current study investigated whether a multidimensional model could underlie impulsivity and its associations with various disorders in a forensic sample. Data were available from self-report and behavioral impulsivity instruments of 87 forensic patients. Principal component analysis (PCA) was used to derive a dimensional impulsivity model, and t...

Accumulating evidence suggests that the Dark Triad of personality (i.e., Narcissism, Psychopathy, and Machiavellianism) is useful in explaining individual differences in adult adjustment. The present study is among the first to examine unique effects of these traits on multi-informant ratings of adolescent aggressive behavior. In two samples (Ns =...

The aim of this study was to identify implicit cognitive predictors of aggressive behavior. Specifically, the predictive value of an attentional bias for aggressive stimuli and automatic association of the self and aggression was examined for reactive and proactive aggressive behavior in a non-clinical sample (N = 90). An Emotional Stroop Task was...

Two cross-sectional studies were conducted to explore the relationship between attachment and the self-conscious emotions of guilt and shame in childhood. Study 1 was performed in non-clinical children aged 9–13 years (N = 688) who completed a single-item measure of attachment style and a vignette-based instrument for assessing guilt and shame. Res...

This study reports reliability and validity of the Dutch Reactive-Proactive Aggression Questionnaire (RPQ). In total, 845 participants completed the RPQ along with other measures of aggression. Groups consisted of non-offender participants, criminal offenders, youngsters (age 6-18), and adults (age above 18). Test-retest stability in a subsample of...

The present research expands our understanding of cognitive and affective morality by exploring associations with callous-unemotional (CU) traits and externalizing symptoms. Participants were 46 8- to 12-year-old boys from the community who completed the Affective Morality Index, the Youth Self-Report, and the Inventory of Callous-Unemotional Trait...

Reactive aggression (RA) refers to angry responses to provocation or frustration, while proactive aggression (PA) denotes nonemotional, instrumental, and unprovoked aggression. The current study examined personality-related and cognitive correlates of both aggressive types. Respectively, the predictive values of antisocial personality disorder (ASP...

The current study reports validation results for the Psychopathic Personality Inventory (PPI) and its subscales, and for a newly developed PPI-Short Form (PPI-SF) in forensic and non-forensic populations. We also provide criterion reference scores for the PPI and the PPI-SF. In Study 1, we used PPI data from 1,065 participants and supplementary PCL...

The objective of this study was to investigate whether levels of psychopathy predicted claims of crime-related amnesia. Different characteristics of psychopathy were based on the factor structure of the self-report questionnaire Psychopathic Personality Inventory (PPI). Crime-related amnesia claims were scored from inmates (N=31) criminal file reco...

Research supports the validity of the dimensional approach to psychopathy in both children and adults. The occurrence of severe aggressive and antisocial behavior in combination with callous-unemotional traits (CU traits) designates a group of children that is particularly at risk to develop psychopathy. However, most studies did not investigate th...

Aggressive individuals often exhibit a hostile attributional bias (HAB). To examine why some people exhibit the HAB to a higher degree than others, we tested the hypothesis put forth by Dodge (2006). Dodge hypothesized HAB results from traumatic experiences and this relation is mediated by schemas. This hypothesis was tested among 135 Dutch and mig...

Findings on executive functioning in psychopathy are inconsistent. Different associations between psychopathy dimensions and executive functioning might explain contradicting findings. This study examined the role of psychopathy dimensions and types of aggression in response inhibition among 117 male adolescents (53 antisocial delinquents and 64 co...

Risk assessment is considered to be a key element in the prevention of recidivism among juvenile sex offenders (JSOs), often by imposing long-term consequences based on that assessment. The authors reviewed the literature on the predictive accuracy of six well-known risk assessment instruments used to appraise risk among JSOs: the Juvenile Sex Offe...

Adult psychopaths have deficits in emotional processing and inhibitory control, engage in morally inappropriate behavior, and generally fail to distinguish moral from conventional violations. These observations, together with a dominant tradition in the discipline which sees emotional processes as causally necessary for moral judgment, have led to...

This article both selectively reviews the evidence supporting the view that reactive and proactive aggression actually reflect related but separate constructs, and also investigates the selective relationship between these forms of aggression and psychopathic personality in 121 male prison inmates. Results show that total psychopathy scores were re...

Previous studies have suggested that offenders have lowered verbal intelligence compared to their performance intelligence. This phenomenon has been linked traditionally to childhood risk factors (e.g. deficient education, abuse and neglect). Substantial discrepancies between performance intelligence quotients (PIQ) and verbal intelligence quotient...

Legal scholars and philosophers have long debated the moral standing of the act-omission distinction, with some favoring the view that actions ought to be considered as morally different from omissions, while others disagree. Several empirical studies suggest that people judge actions that cause harm as worse than omissions that cause the same harm...

The current study assesses whether patients and therapists report similar levels of schema modes, one of the central features in Schema-Focused Therapy. Patient's self-report and therapists' report on an abbreviated Schema Mode Inventory were compared in a sample of 92 patients with antisocial, borderline or cluster C personality disorder. Results...

Anger is the main deregulated emotion in patients with antisocial personality disorder (ASPD). The aim of this study was to examine emotional, cognitive and physiological correlates of anger and compare these between ASPD patients with varying degree of psychopathy (PP) and control groups. Assessment of the effect of anger induction on self-reporte...

The current research addresses the psychometric and diagnostic qualities of the Supernormality Scale-Revised (SS-R), a self-report measurement. Supernormality is defined as the tendency to systematically deny the presence of common symptoms (e.g., intrusive thoughts). In study 1, the SS-R was administered to forensic patients (n = 63), psychiatric...

The relationship between self-reported traumatic childhood experiences, cortisol levels, aggression, and psychopathy was investigated in prison inmates (n=47) and healthy controls (n=27). Besides questionnaires, a brief salivary diurnal profile was measured. Results show that criminals (both psychopaths and non-psychopaths) demonstrate more traumat...

The present study examined how acute dissociation, trait-like dissociative symptoms, and physiological reactivity relate to each other. Sixty-nine undergraduate students were exposed to 14 aversive auditory probes, while their skin conductance responses were measured. A combination of self-reported anxiety and trait-like dissociation was found to p...

To date, no study has systematically investigated moral emotions in impulsive versus predatory psychopathy. Therefore, the objective of this study was to investigate whether these two subtypes of psychopathy differed in their sense of moral emotions. In the current study, 55 prison inmates completed two implicit computer tasks: one task measuring t...

Forensic psychology is a broad spectrum of topics related to both psychology and law issues. One of the more clinical issues involved in forensic psychology is the concept of criminal behaviour, in particular psychopathy. Although the construct of psychopathy has been the subject of a great deal of research, much still remains unclear. Biological f...

Schizophrenic patients have difficulties in recognising previously presented verbal information and identifying its sources. The antecedents of these recognition and source misattributions are, however, largely unknown. The current study examined to what extent schizophrenic patients' lack of memory efficiency, their memory errors, and their source...

The current article addresses the psychometric qualities of the German Version of Gudjonsson's Blame Attribution Inventory (GBAI), a self-report scale for measuring attribution of blame for crime. The GBAI was administered to a criminal sample of forensic and criminal inmates (n=107). Findings indicate that the German version of the Gudjonsson Blam...

After more than 60 years, the ‘Nederlands Tijdschrift voor de Psychologie en haar Grensgebieden’ has undergone a change of identity. First of all, the Journal has changed its name into the ‘Netherlands Journal of Psychology’. Secondly, from now on the Journal will only publish papers that are written in English. Finally, the cover of the Journal ha...

Het komt geregeld voor dat daders zeggen geen enkele herinnering te hebben aan het door hen gepleegde misdrijf. Zo’n vorm van amnesie kan gesimuleerd zijn, maar dat hoeft niet. In het laatste geval spelen negatieve verwachtingen over het eigen geheugen mogelijk een sleutelrol. Bij twee daders die werden behandeld in een forensische kliniek, gingen...

Many authors assume that crime-related amnesia arises from the stressful nature of crimes and/or drug intoxication at the time crimes are committed. The current study examined prevalence and correlates of crime-related amnesia in a German (n=180) and a Dutch (n=128) sample of forensic inmates. More specifically, patients claiming amnesia and contro...

Psychiatric and criminal backgrounds of 111 forensic patients suffering from Axis-I psychotic disorders were compared with those of 197 non-psychotic offenders residing in the same forensic psychiatric hospitals in Germany and the Netherlands. When compared with non-psychotic offenders, psychotic offenders were more often first-time offenders who h...

Dissociation is often considered to be a psychological defense mechanism used by victims of traumatic events (e. g., sexual abuse, physical punishment, or emotional abuse). Evidence for this view comes from studies that found a connection between self-reported traumatic childhood experiences and high levels of dissociation. However, there are some...

The current article addresses the psychometric qualities of the German version of the Structured Inventory of Malingered Symptomatology (SIMS), a self-report measure of malingering. The SIMS was administered to a heterogeneous sample of forensic patients (n=62) and undergraduate students (n=204). Within the student sample, some undergraduates were...

The current study explored characteristics of psychiatric prison inmates who claim amnesia for their crimes. More specifically, we examined differences in intelligence, psychopathology, executive functions, and malingering tendencies between psychiatric prison inmates who claimed amnesia (n=17) and those who did not (n=45). Findings indicate that l...
