Network approaches to psychometric constructs, in which constructs are modeled in terms of interactions between their constituent factors, have rapidly gained popularity in psychology. Applications of such network approaches to various psychological constructs have recently moved from a descriptive stance, in which the goal is to estimate the network structure that pertains to a construct, to a more comparative stance, in which the goal is to compare network structures across populations. However, the statistical tools to do so are lacking. In this article, we present the network comparison test (NCT), which uses resampling-based permutation testing to compare network structures from two independent, cross-sectional data sets on invariance of (a) network structure, (b) edge (connection) strength, and (c) global strength. Performance of NCT is evaluated in simulations that show NCT to perform well in various circumstances for all three tests: The Type I error rate is close to the nominal significance level, and power proves sufficiently high if sample size and difference between networks are substantial. We illustrate NCT by comparing depression symptom networks of males and females. Possible extensions of NCT are discussed. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Absence of a common diagnostic interview has hampered cross-national syntheses of epidemiological evidence on major depressive episodes (MDE). Community epidemiological surveys using the World Health Organization Composite International Diagnostic Interview administered face-to-face were carried out in 10 countries in North America (Canada and the US), Latin America (Brazil, Chile, and Mexico), Europe (Czech Republic, Germany, the Netherlands, and Turkey), and Asia (Japan). The total sample size was more than 37,000. Lifetime prevalence estimates of hierarchy-free DSM-III-R/DSM-IV MDE varied widely, from 3% in Japan to 16.9% in the US, with the majority in the range of 8% to 12%. The 12-month/lifetime prevalence ratio was in the range 40% to 55%, the 30-day/12-month prevalence ratio in the range 45% to 65%, and median age of onset in the range 20 to 25 in most countries. Consistent socio-demographic correlates included being female and unmarried. Respondents in recent cohorts reported higher lifetime prevalence, but lower persistence than those in earlier cohorts. Major depressive episodes were found to be strongly co-morbid with, and temporally secondary to, anxiety disorders in all countries, with primary panic and generalized anxiety disorders the most powerful predictors of the first onset of secondary MDE. Major depressive episodes are a commonly occurring disorder that usually has a chronic-intermittent course. Effectiveness trials are needed to evaluate the impact of early detection and treatment on the course of MDE as well as to evaluate whether timely treatment of primary anxiety disorders would reduce the subsequent onset, persistence, and severity of secondary MDE.

The relationship between ethnicity and health is attracting increasing attention in international health research. Different measures are used to operationalise the concept of ethnicity. Presently, self-definition of ethnicity seems to gain favour. In contrast, in the Netherlands, the use of country of birth criteria have been widely accepted as a basis for the identification of ethnic groups. In this paper, we will discuss its advantages as well as its limitations and the solutions to these limitations from the Dutch perspective with a special focus on survey studies. The country of birth indicator has the advantage of being objective and stable, allowing for comparisons over time and between studies. Inclusion of parental country of birth provides an additional advantage for identifying the second-generation ethnic groups. The main criticisms of this indicator seem to refer to its validity. The basis for this criticism is, firstly, the argument that people who are born in the same country might have a different ethnic background. In the Dutch context, this limitation can be addressed by the employment of additional indicators such as geographical origin, language, and self-identified ethnic group. Secondly, the country of birth classification has been criticised for not covering all dimensions of ethnicity, such as culture and ethnic identity. We demonstrate in this paper how this criticism can be addressed by the use of additional indicators. In conclusion, in the Dutch context, country of birth can be considered a useful indicator for ethnicity if complemented with additional indicators to, first, compensate for the drawbacks in certain conditions, and second, shed light on the mechanisms underlying the association between ethnicity and health.

This paper presents the main findings of quantitative and qualitative research into the criminal careers of about 1000 offenders who were involved in 80 extensively analysed cases of organized crime. The paper analyses how and when offenders become known to the criminal justice authorities, studies in depth the criminal careers of `starters' and analyses in detail the criminal careers of (ring)leaders and `nodal' offenders. Because social ties play an important role in organized crime, the paper emphasizes that the social opportunity structure, defined as social ties providing access to profitable criminal opportunities, is extremely important for explaining involvement in organized crime. It explains why certain offenders `progress' to certain types of organized crime whereas others become involved only later on in life. Social opportunity structure may also explain interesting phenomena such as `late starters' — people without any appreciable criminal history — and people in conventional jobs who switch careers.

OBJECTIVE: To examine the diagnostic value of self-reported psychotic-like experiences for DSM-III-R psychotic disorders. METHOD: A general population sample of 7076 subjects aged 18-64 years was interviewed with the Composite International Diagnostic Interview (CIDI) and, if there was evidence of psychotic experiences, the Structured Clinical Interview for DSM-III-R. RESULTS: The probability of having a psychotic disorder increased in a dose-response fashion with the level of self-reported psychotic experiences, but individual CIDI psychotic experience ratings had relatively low post-test probabilities (PPs) (range: 5.1-26.5%). However, limiting the sample to individuals who had been in contact with mental health services substantially improved PPs (range: 13.3-43.1%). CONCLUSION: Screening for psychosis in the population carries a high risk of stigmatization in false-positive cases and violation of the right 'not to know' in true-positive cases. However, in mental health care users, self-reported psychotic experiences may be a useful screening tool in individuals who have already developed help-seeking.

Abstract Intergroup contact is an established pathway to improve intergroup relations. Research has long focused on mainly positive intergroup contact and its capability to improve intergroup relations. Yet, if members of different groups meet, they will not only make positive, but possibly also negative intergroup contact experiences. Recent research considering both positive as well as negative intergroup contact has raised concerns about potentially stronger effects of negative compared to positive contact. These new insights and the increasing awareness of potentially detrimental effects of contact could lead to doubts about whether it is always sensible to bring individuals from different groups together. Our article first updates the latest review on joint effects of positive and negative intergroup contact. We find that there is no clear tendency for either positive or negative intergroup contact to yield stronger effects on intergroup relations, and we portray factors that might influence these effects. Such factors—for example an individual's prior experiences—could play a crucial role in defining the relevance of negative contact in everyday settings. We continue by answering calls to increase a more qualitative understanding of what kinds of experiences are seen to be intergroup contact, and where intergroup contact in everyday life is experienced from a lay understanding, with new qualitative data from British White and British Asian individuals. Our results demonstrate that positive as well as negative contact is often rather casual and happens in public spaces and at work. Interventions explicitly addressing these spaces may help to reach more people. We also demonstrate that positive contact is much more frequent than negative contact. This finding is confirmed in the third section, which reviews the relative frequency of positive and negative intergroup contact. Last but not least, we discuss the implications of our review for practitioners and researchers alike.

Scholars in the field of developmental criminology traditionally assign a major role to long-term risk factors such as inadequate parental supervision or poor school performance. Only recently has attention been paid to the effects of situational risk factors such as the presence of co-offenders and being drunk. Hardly any empirical research, however, integrates both long-term and short-term risk factors. We formulated hypotheses derived from the Integrated Cognitive Antisocial Potential theory (Farrington 2005) with regard to long-term and short-term risk factors for serious delinquency, and tested these hypotheses using data from the WODC Youth Delinquency Survey (data sweep 2005) of 292 juvenile delinquents. The findings indicate that serious delinquency is related not only to (an accumulation of) long-term risk factors, but also to situational factors, such as lack of tangible guardians and having used substances (alcohol or drugs) prior to the offence.

, respectively). The effect size remained large in prospective longitudinal studies up to one year after trauma. There was no moderation effect for civilian vs military populations, questionnaire vs interview measures of PTSD, single vs multiple trauma exposure, or intentional vs unintentional trauma. The main effect size estimate was robust to sensitivity analyses concerning statistics used, study quality and outliers. These findings are consistent with the strong role for maladaptive appraisals in the aetiology of PTSD proposed by cognitive models. In particular, the role of self-appraisals in adults was highlighted. Avenues for future research include more studies in child, multiple trauma and military populations and longer-term follow up studies.

This article presents an approach to systematic reviews that combines the Campbell Collaboration Crime and Justice standards and the realist notion of contexts-mechanisms-outcomes (CMO) configurations. Both approaches have their advantages and drawbacks, and the authors will make a case for combining both approaches to profit from their advantages without having to deal with their separate weaknesses. They proceed to discuss how their approach should be put into practice and illustrate its use by giving a concise description of an example from their own work on the effects of prevention of violence. The authors conclude with a discussion of the strengths and weaknesses of their suggested approach and state that combining Campbell standards and the realist evaluation approach should be done more often.

This study uses longitudinal official record data on adult offenders in The Netherlands (n = 4,246) to compare recidivism after community service to that after short-term imprisonment. To account for possible bias due to selection of offenders into these types of sanctions, we control for a large set of confounding variables using a combined method of ‘matching by variable’ and ‘propensity score matching’. Our findings demonstrate that offenders recidivate significantly less after having performed community service compared to after having been imprisoned. This finding holds for both the short- and long-term. Furthermore, using the Rosenbaum bounds method, we show that the results are robust for hidden bias.

Research into international migration lacks a commonly accepted theoretical framework, which would facilitate the accumulation of knowledge. This article aims to be a first attempt to construct such a framework and to incorporate causalities in the international migration systems approach. The author presents a theoretical framework in which four groups of factors acting on international migration are distinguished: economic, social, political and “linkages.” The causalities in this framework are derived from different international migration theories. The various positions of these whole theories within the framework are shown as causality chains. In a way, these causality chains form the time dimension of an international migration system

OBJECTIVE: To examine the hypothesis that the risk for onset of psychotic disorder in individuals with self-reported hallucinatory experiences (HE) would be higher in those who developed delusional ideation (DE) than in those who did not. METHOD: A population sample of 4673 individuals were interviewed with the Composite International Diagnostic Interview at baseline and 1 and 3 years later. At year 3, clinical re-interview took place to identify onset of psychotic disorder. RESULTS: Given the presence of HEs at baseline, the increase in risk of having the psychosis outcome at year 3 was much higher in those with DE at year 1 than in those without DE (risk difference between individuals with and without DE: 18.72%, 95% CI: 2.22-35.23, chi(2) = 4.94, df = 1, P = 0.026). CONCLUSION: The results are in line with current psychological theories stating that clinical outcome of psychosis-like experiences is related to the development of secondary beliefs and appraisals.

A humane and fair treatment of prisoners is of intrinsic value in itself, and is generally acclaimed to reduce prisoners' psychological distress and misconduct in prison, and their criminal behavior after release from prison. To create a more just prison climate, scholars have emphasized the importance of correctional staff. However, there is a lack of empirical research on the relationship between correctional officers' characteristics and prisoners' perceptions of a just treatment in prison. Our study fills this gap in knowledge. Data were used from (a) the Prison Project, a large-scale study in which prisoners held in all Dutch remand centers were surveyed (n = 1,610) and (b) the Dutch Correctional Staff Survey 2011 (n = 690). Multilevel analyses showed that prisoners perceived their treatment in prison as more procedurally just in units where there are more female officers, where officers held more positive attitudes toward rehabilitation, and where there is a higher officer-to-inmate ratio.

OBJECTIVE: In a cohort of subjects with no history of psychopathology, we determined a 3-year incidence and the risk factors of comorbid and pure mood, anxiety and substance use disorders. METHOD: Data were obtained from the Netherlands Mental Health Survey and Incidence Study (NEMESIS), a longitudinal community study in which 4796 adults were interviewed in 1996, 1997 and 1999 with the Composite International Diagnostic Interview. RESULTS: Of 2869 cases at risk, 10.8% developed an incident disorder within 3 years, of which 16.1% was comorbid. Neuroticism, childhood trauma and parental psychiatric history were more strongly associated with comorbid than with pure disorders. No differences emerged in events occurring in the first year after baseline, but events in the period thereafter showed markedly stronger associations with comorbidity and pure mood disorder than with pure anxiety and substance use disorder. Functional disability was also linked more strongly to comorbidity and pure mood disorder. CONCLUSION: Clear risk factors exist for the rapid onset of comorbidity. Interventions are needed to prevent rapid comorbidity in subjects who recently developed a primary disorder.

This paper investigates criminal trajectories of individuals who are involved in organized crime. A semiparametric group-model is used to cluster 854 individuals into groups with similar developmental trajectories. The most important fi ndings of the study relate to the substantial group of adult-onset offenders (40 per cent) and a group without any previous criminal records (19 per cent), next to a group of early starters (11 per cent) and a group of persisters (30 per cent). Up to date, no trajectory study has discovered such a vast share of adult-onset offenders. Furthermore, the fi ndings turn out to be quite robust, if trajectory analyses are applied to different kinds of criminal activities and to different roles in criminal groups.

Abstract States experience difficulties in realizing the return of rejected asylum seekers, but migration control policies are becoming increasingly sophisticated. Against this background, we consider explanations for the increase in Assisted Voluntary Return from the Netherlands in the 2005–2011 period. Both macro‐level factors (source country societal conditions and characteristics of the Dutch “deportation regime”) and individual‐level factors (applicants' demographic characteristics and variation in status determination time) are examined. The study, which is based on a unique multilevel dataset ( N = 15,682) with data from governmental and other sources (including International Organisation for Migration), is the first to quantitatively test assumed Assisted Voluntary Return determinants and contributes to the study of policy effects in migration studies. We find that states are capable of increasing return rates by expanding the use of “hard” and “soft” power. We propose the term “soft deportation” as a way to go beyond the dichotomy of “voluntary” and “forced” return.

This paper elaborates upon occupations, work relations, work settings, and their connection with organised crime activities. The analysis is based upon data from 120 case studies from the Dutch Organised Crime Monitor, involving 1623 suspects. The paper describes the different kinds of occupations encountered in cases of organised crime and the main characteristics of these occupations. Furthermore, the paper describes in more detail four cases of organised crime that illustrate the embeddedness of certain organised crime activities in work relations and work settings. Following Mars,1 1. Gerald Mars, Cheats at Work: An Anthropology of Workplace Crime (London: Unwin Paperbacks, 1982). the paper analyses both the grid dimension and the group dimension of certain occupations and work settings. The paper concludes that social relations as well as settings and opportunity structures provide structure to the organisation of many forms of crime, including organised crime.

<p>Prosociality is a central topic in positive psychology. An important but under-studied distinction can be made between active and reactive expressions. We suggest that the novel construct of social mindfulness represents active rather than reactive prosociality. Across four studies (<i>N</i> = 2,594), including a multi-wave representative sample spanning six years, social mindfulness is found to correlate with personality traits associated with prosocial and/or antisocial behavior. We find positive associations with empathy, social value orientation, and general prosocial behavior, and negative associations with moral disengagement and narcissism. Importantly, social mindfulness emerges as an active rather than a reactive characteristic that is more strongly related to HEXACO honesty-humility (active cooperation) than to HEXACO agreeableness (reactive cooperation). The association between social mindfulness and honesty-humility was found across measures six years apart. Given the well-established link between prosociality and well-being, emphasizing social mindfulness may be a good start to promote the latter.<br></p>

One of the goals of the journal Evaluation was to advance theoretical and methodological understandings of evaluation. Twenty years later theory as understood in the field of evaluation is fragmented, a problem widely recognized in the evaluation community. The goal of this article is to make a modest contribution to clarifying this situation. We first present two typologies of evaluation theory and invite readers to join us in a discussion of the pros and cons of these typologies. We then present an impressionistic picture, mainly qualitative, of how ‘theory’ has featured in past issues of this journal. Many articles with a theoretical orientation have been published in Evaluation providing a rich though somewhat diffuse picture in which many of the types identified in our typologies are represented. Finally several suggestions are put forward to further strengthen the development of theoretical work in the evaluation profession. These are ‘theory knitting’, ‘theory layering’ and ‘theory-driven evaluation science’.

In this contribution an empirical approach is used to gain more insight into the relationship between neuroscience and criminal law. The focus is on case law in the Netherlands. Neuroscientific information and techniques have found their way into the courts of the Netherlands. Furthermore, following an Italian case in which a mentally ill offender received a penalty reduction in part because of a 'genetic vulnerability for impulsive aggression', the expectation was expressed that such 'genetic defenses' would appear in the Netherlands too. To assess how neuroscientific and behavioral genetic information are used in criminal justice practice in the Netherlands, we systematically collect Dutch criminal cases in which neuroscientific or behavioral genetic information is introduced. Data and case law examples are presented and discussed. Although cases are diverse, several themes appear, such as prefrontal brain damage in relation to criminal responsibility and recidivism risk, and divergent views of the implications of neurobiological knowledge about addiction for judging criminal responsibility. Whereas in the international 'neurolaw literature' the emphasis is often on imaging techniques, the Dutch findings also illustrate the role of neuropsychological methods in criminal cases. Finally, there appears to be a clear need of practice oriented instruments and guidelines.
