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.

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.

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.

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.

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.

Protocol of a monocentric, double-blind, randomized, superiority, controlled trial evaluating the effect of in-prison OROS-methylphenidate vs. placebo treatment in detained people with attention-deficit hyperactivity disorder (BATIR).

Background: Attention-deficit hyperactivity disorder (ADHD) is characterized by difficulty paying attention, poor impulse control, and hyperactive behavior. It is associated with several adverse health and social outcomes and leads to an increased risk of criminality and recidivism. Worldwide, ADHD is thus highly prevalent in prisons.

Why do we never have enough time? Economic inequality fuels the perception of time poverty by aggravating status anxiety.

People in many societies report that they do not have enough time. What makes people feel so rushed? We propose that economic inequality leads to perceived time poverty by increasing status anxiety. Five studies examined this line of reasoning.

Direct and Indirect Genetic Effects on Aggression.

Background: Family members resemble each other in their propensity for aggression. In twin studies, approximately 50% of the variance in aggression can be explained by genetic influences. However, if there are genotype-environment correlation mechanisms, such as environmental manifestations of parental and sibling genotypes, genetic influences may partly reflect environmental influences.

How does economic inequality shape conspiracy theories? Empirical evidence from China.

Conspiracy theories tend to be prevalent, particularly in societies with high economic inequality. However, few studies have examined the relationship between economic inequality and belief in conspiracy theories. We propose that economic inequality leads people to believe conspiracy theories about economically advantaged groups (i.

Changing perspectives: enhancing learning efficacy with the after-action review in virtual reality training for police.

The After-Action Review (AAR) in Virtual Reality (VR) training for police provides new opportunities to enhance learning. We investigated whether perspectives (bird's eye & police officer, bird's eye & suspect, bird's eye) and line of fire displayed in the AAR impacted the officers' learning efficacy. A 3 x 2 ANOVA revealed a significant main effect of AAR perspectives.

Online Communities for Child-Attracted Persons as Informal Mental Health Care: Exploring Self-Reported Wellbeing Outcomes.

Online support communities are gaining attention among child-attracted persons (CAPs). Though research has largely focused on the negative consequences these environments create for potential offending, they may also provide a beneficial alternative to more formal treatment settings. To assess the utility for clinical and therapeutic purposes, this analysis focused on subcultural dynamics to examine self-reported wellbeing outcomes of participation in a Dutch forum for CAPs.

No pain, no gain? The effects of adding a pain stimulus in virtual training for police officers.

Virtual training systems provide highly realistic training environments for police. This study assesses whether a pain stimulus can enhance the training responses and sense of the presence of these systems. Police officers ( = 219) were trained either with or without a pain stimulus in a 2D simulator (VirTra V-300) and a 3D virtual reality (VR) system.

Corrupt third parties undermine trust and prosocial behaviour between people.

Corruption is a pervasive phenomenon that affects the quality of institutions, undermines economic growth and exacerbates inequalities around the globe. Here we tested whether perceiving representatives of institutions as corrupt undermines trust and subsequent prosocial behaviour among strangers. We developed an experimental game paradigm modelling representatives as third-party punishers to manipulate or assess corruption and examine its relationship with trust and prosociality (trust behaviour, cooperation and generosity).

Unravelling the relationship between populism and belief in conspiracy theories: The role of cynicism, powerlessness and zero-sum thinking.

In recent years, it has been argued that conspiracy beliefs and populist attitudes go hand in hand. Despite their theoretical and empirical similarities, it remains unclear why these constructs are so closely associated. Across three studies, we examined the processes underlying the relationship between belief in conspiracy theories and populist attitudes.

A longitudinal analysis of conspiracy beliefs and Covid-19 health responses.

Background: Little is known about how conspiracy beliefs and health responses are interrelated over time during the course of the coronavirus disease 2019 (Covid-19) pandemic. This longitudinal study tested two contrasting, but not mutually exclusive, hypotheses through cross-lagged modeling. First, based on the consequential nature of conspiracy beliefs, we hypothesize that conspiracy beliefs predict an increase in detrimental health responses over time.

"The Glass is Half Full": Narratives from Young Adults on Parental Incarceration and Emerging Adulthood.

Prior literature highlights that children of incarcerated parents are more likely to endure negative life outcomes. Yet, this discussion is mainly centered on the immediate impacts of parental incarceration during childhood and adolescent years, with less focus on the longer-term consequences as these children emerge into adulthood. This study examined how young adults interpreted their experience of parental incarceration.

No causal relationship between early motherhood and offspring adolescent offending: Empirical evidence from a genetically-informed study.

Previous studies have consistently shown that young maternal age at birth is associated with an increased risk for problematic behavior in offspring. Less is known about the mechanisms underlying this association, as it could either reflect a causal effect or a spurious relationship. This study aims to gain more insights in these underlying mechanisms by studying the relationship between early motherhood and offspring adolescent offending.

Implementing "Online Communities" for pregnant women in times of COVID-19 for the promotion of maternal well-being and mother-to-infant bonding: a pretest-posttest study.

Background: The Coronavirus Disease 2019 (COVID-19) pandemic elevated the risk for mental health problems in pregnant women, thereby increasing the risk for long-term negative consequences for mother and child well-being. There was an immediate need for easily accessible interventions for pregnant women experiencing elevated levels of pandemic related stress.

Methods: A three-session intervention "Online Communities" (OC) was developed at the beginning of the Dutch lockdown, and implemented by a team of midwives and psychologists specialized in Infant Mental Health.

Alerting consciences to reduce cybercrime: a quasi-experimental design using warning banners.

Objective: Aiming to reduce distributed denial-of-service (DDoS) attacks by alerting the consciences of Internet users, this paper evaluates the effectiveness of four warning banners displayed as online ads (deterrent-control, social, informative, and reorienting) and the contents of their two linked landing pages.

Methods: We implement a 4 × 2 quasi-experimental design on a self-selected sample of Internet users to measure the engagement generated by the ads and the pages. Engagement is measured on the ads as the ratio of clicks to impressions and on the pages as percentage of page scrolled, average session duration, video interaction rate, and URLs click rate.

No evidence that mask-wearing in public places elicits risk compensation behavior during the COVID-19 pandemic.

Face masks have been widely employed as a personal protective measure during the COVID-19 pandemic. However, concerns remain that masks create a false sense of security that reduces adherence to other public health measures, including social distancing. This paper tested whether mask-wearing was negatively associated with social distancing compliance.

Residents, Employees and Visitors: Effects of Three Types of Ambient Population on Theft on Weekdays and Weekends in Beijing, China.

Objectives: The residential population of an area is an incomplete measure of the number of people that are momentarily present in the area, and of limited value as an indicator of exposure to the risk of crime. By accounting for the mobility of the population, measures of ambient population better reflect the momentary presence of people. They have therefore become an alternative indicator of exposure to the risk of crime.

The use of professional help and predictors of unmet needs for dealing with mental health to legal problems among victims of violence, accidents, theft and threat, and nonvictims in the general population.

Aims: Victims of violence, accidents, theft, and serious threat (hereafter abbreviated as victims) are more than nonvictims at risk for problems in different domains, varying from mental health to legal problems. However, the extent to which victims with these problems compared to nonvictims with similar problems receive problem-related professional or formal help is unclear. It is unknown if predictors of unmet needs differ between victims and nonvictims.

The Key Characteristics and Role of Peer Support in the Aftermath of Victimization: A Scoping Review.

Topic: Currently, research into the key elements and role of peer support in the aftermath of victimization is limited. This study reviews the types of evidence available, clarifying key concepts in the literature, examining how research is conducted and identifying key characteristics or factors related to peer support in the aftermath of a victimization experience.

Method: A scoping review was performed for peer-reviewed papers using predefined search terms.
