The DID-guide: A guide to developing digital mental health interventions.

The opportunities technology offers for improving mental health have led to a surge in digital interventions. A pivotal step in the development of such interventions involves translating theoretical intervention techniques into specific technological features. However, practical guidelines on how to approach this translation are currently underdeveloped.

Negative Life Events and Epigenetic Ageing: A Study in the Netherlands Twin Register.

We aimed to understand the long-term impact of negative life events on epigenetic aging in 1783 adults from the Netherlands Twin Register, analyzing five epigenetic biomarkers (Hannum, Horvath, PhenoAge, GrimAge, DunedinPACE) and a series of negative life events, including victimization and economic hardship. In population-level analyses, associations between a higher number of negative life events (particularly financial adversities, sexual crimes, and job loss) were seen for the GrimAge biomarker. The association between the number of negative life events and financial problems and epigenetic age acceleration measured by the GrimAge biomarker persisted after adjusting for BMI, smoking, and white blood cell counts.

Delusion-proneness predicts COVID-19 vaccination behavior.

Introduction: Vaccination-related conspiracy ideation is related to reduced compliance with public health advice globally. Such beliefs have previously been linked to the delusion-proneness trait. However, it is not known how this extends to getting vaccinated.

Evaluating the validity of testimony: The role of the order of evidence.

Legal practitioners sometimes ask psychologists to evaluate the validity of statements of victims, witnesses, and suspects. For their assessment, psychologists often have access to different pieces of evidence (e.g.

Being in two minds: accommodating emotional victim narratives in Dutch courtrooms.

When Victim Impact Statements (VISs) were introduced in Dutch criminal law in 2005, victims were required to limit their statement to the impact of the harm done by the crime. In 2016, a major amendment lifted this restriction. Even though the statement may (still) not be used as legal evidence, critics worried that the change in scope would invite heightened levels of emotion into the courtroom, which would in turn undermine magistrates' objectivity.

Teeth Baring as a Model to Understand Complex Facial Signals in a Tolerant Macaque Species.

Facial communication regulates many aspects of social life in human and nonhuman primates. Empirically identifying distinct facial expressions and their underlying functions can help illuminate the evolution of species' communicative complexity. We focused on bared-teeth faces (BTFs), a highly versatile facial expression in the tolerant macaque Macaca tonkeana.

The Effect of 6 weeks Physical Activity on Cognitive Control and Trait Impulsivity in Multi-problem Young Adults: First Findings of an RCT-study.

This study aimed to report the effect of a 6-week light-active versus moderate-active physical activity intervention embedded in a multimodal day treatment program on selected measures of cognitive control (i.e., response inhibition, error processing, and cognitive interference) and trait impulsivity.

Genetic Influence on Social Support: A Twin Study.

Social support is often considered an environmental factor affecting health, especially in aging populations. However, its genetic underpinnings suggest a more complex origin. This study investigates the heritability of social support through applying a threshold model on data of a large adult sample of twins ( = 8019) from the Netherlands Twin Register, collected between 2009 and 2011.

A Comparative Study of the Help-Seeking Behavior of Victims of Contact Sexual Violence and Image-Based Sexual Harassment and Abuse.

Sexual victimization may have serious consequences for victims' well-being. Thus, seeking support is encouraged and associated with positive outcomes. However, no research has compared the help-seeking behavior of victims of contact and image-based (i.

Changes in Probation Officer Procedural Justice and Self-Reported Recidivism.

An increasing number of studies has studied the role of procedural justice for reducing recidivism in the probation context. The objective of this study is to contribute to existing knowledge by examining (a) whether people on probation alter their perceptions of probation officer procedural justice over time and (b) the extent to which changes in procedural justice relate to recidivism. This study utilized longitudinal data from 326 adults who were released from Dutch (pre-trial) detention centers and who had contact with the Probation Service.

Patient perspectives on adverse event investigations in health care.

Background: Over the last decade attention has grown to give patients and next of kin (P/N) more substantial roles in adverse event investigations. Adverse event investigations occur after adverse events that resulted in death or severe injury. Few studies have focused on patient perspectives on their involvement in such investigations.

Bystander Action Beyond Intervention: Video-Observing the Bystander Behavior of Men and Women in Real-Life Public Conflicts.

Previous research suggests that bystanders of conflicts use a range of intervention strategies. Yet, much less is known about other actions-beyond intervention-that bystanders might engage in during conflicts. Further, while prior studies reveal that gender differences emerge in bystander behavior, few studies have assessed the ecological validity of such potential differences in bystander actions during real-life conflicts.

Introducing the high-context communication style interview protocol to detect deception in pairs.

In four experiments, we examined whether pairs of truth tellers could be distinguished from pairs of lie tellers by taking advantage of the fact that only pairs of truth tellers can refer to shared events by using brief expressions (high-context communication style). In Experiments 1 and 2, pairs of friends and pairs of strangers pretending to be friends answered (i) questions they likely had expected to be asked (e.g.

Early warning signals for predicting cryptomarket vendor success using dark net forum networks.

In this work we focus on identifying key players in dark net cryptomarkets that facilitate online trade of illegal goods. Law enforcement aims to disrupt criminal activity conducted through these markets by targeting key players vital to the market's existence and success. We particularly focus on detecting successful vendors responsible for the majority of illegal trade.

System-justifying beliefs buffer against psychological distress during the COVID-19 pandemic.

The coronavirus disease 2019 (COVID-19) pandemic has had a detrimental effect on people's mental health. Drawing on the palliative function of ideologies, we suggest that people rely on system-justifying beliefs to mitigate psychological distress during the pandemic. We conducted three studies with correlational and experimental designs to examine whether and how system-justifying beliefs can buffer against psychological distress during COVID-19, and whether this effect may vary across social classes.

"I Did Not Want to Make a Bigger Deal Out of It than It Was": A Mixed-Method Study on the Help-Seeking Behavior of Victims of Image-Based Sexual Harassment and Abuse.

Experiencing image-based sexual harassment and abuse (IBSHA), or the sending of unsolicited nude or sexual images and the nonconsensual taking, sharing, or threats to share nude or sexual images, may have severe consequences for victims' well-being. While seeking help may be beneficial, not every victim seeks help. Little research has been conducted on IBSHA victims' help-seeking behavior.

Same-Sex Relationships and Criminal Behavior: A Total Population Study in The Netherlands.

Sexual minority groups experience elevated risk across a range of adverse outcomes. Previous studies from the USA showed that these risks include contact with the criminal justice system for sexual minority females but not for males. This study examined whether this relationship between sexual minority status and criminal behavior was also found in a more secular country like the Netherlands with more progressive attitudes toward sexual minorities.

Rejection of the status quo: Conspiracy theories and preference for alternative political systems.

Conspiracy theories introduce a democratic paradox, as belief in conspiracy theories predicts support for both democratic and non-democratic political systems. In this article, we explore whether democratic and anti-democratic attitudes, resulting from conspiracy beliefs, can be mutually exclusive. In Study 1 (United Kingdom, N = 293), we show that belief in conspiracy theories is associated with decreased support for representative democracy, and increased support for direct democracy, anarchism, and autocracy within the same individuals.

Anti-establishment sentiments: realistic and symbolic threat appraisals predict populist attitudes and conspiracy mentality.

Previous research has found that populist attitudes and conspiracy mentality - here summarised as anti-establishment attitudes - increase when people feel threatened. Two types of intergroup threat have been distinguished, namely realistic threats (pertaining to socio-economic resources, climate, or health), and symbolic threats (pertaining to cultural values). However, there is no agreement on which types of threat and corresponding appraisals would be most important in predicting anti-establishment attitudes.

Why do users continue to contribute to darknet Child Sexual Abuse Material forums? Examining social exchange, social capital, and social learning explanations using digital forensic artifacts.

Background: The darknet hosts an increasing number of hidden services dedicated to the distribution of child sexual abuse material (CSAM). Given that by contributing CSAM to the forum members subject themselves to criminal prosecution, questions regarding the motivation for members contributing to darknet CSAM forums arise.

Objective: Building on insights gained from research into clearnet communities, here we examine the extent to which social incentives generated by the online CSAM community may explain members' posting behavior on darknet CSAM forums.

It's Just a Distance Thing: Affordances and Decisions in Online Disclosure of Sexual Violence Victimization.

The Internet offers an alternative context in which personal experiences with sexual violence can be shared. It has been suggested that victims experience lower barriers to disclosing their stories in a digital environment due to an online disinhibition effect and mainly anonymity. However, little is known about the lived experiences of victims who have shared their experiences online regarding these disinhibiting affordances of the Internet.

How perceived coercion polarizes unvaccinated people: The mediating role of conspiracy beliefs.

During the COVID-19 pandemic, different policies were implemented to increase vaccination uptake. Meanwhile, conspiracy theories spread widely, and vaccinated versus unvaccinated people increasingly polarized against each other. This study examined the associations between perceived vaccination coercion, conspiracy beliefs and polarization.

Procedural Justice in Their Eyes: A Qualitative Interview Study Among Detainees.

The literature on procedural justice has been mainly focused on examining whether a fair and respectful treatment affects justice-involved individuals' legitimacy evaluations and their behavior. It is, however, equally important to examine (a) the role that perceptions of procedural justice play for individuals in their encounters with criminal justice authorities and (b) what makes individuals feel treated procedurally (un-)just. In this qualitative study, semi-structured interviews were conducted with 35 detainees in a Dutch prison, asking questions about their encounters with police officers, prison staff, judges, and probation officers.
