Understanding the effects of conceptual and analytical choices on ‘finding’ the privacy paradox: A specification curve analysis of large-scale survey data

Philipp K. Masur
The privacy paradox suggests that privacy concerns do not relate to privacy-related behavior. Although it has inspired numerous studies, findings remain inconclusive. Some of the inconsistencies in published findings may be explained by a strong heterogeneity in the conceptual and analytical choices that researchers implement when investigating the privacy paradox. Based on representative survey data of the 27 EU member states (2011: n = 8,962; 2015: n = 10,526; 2019: n = 11,428), I investigated...

Ilja M. J. Saris, Moji Aghajani, Lianne M. Reus, Pieter-Jelle Visser, Yolande Pijnenburg, Nic J. A. van der Wee, Amy C. Bilderbeck, Andreea Raslescu, Asad Malik, Maarten Mennes, Sanne Koops, Celso Arrango, Jose Luis Ayuso-Mateos, Gerard R. Dawson, Hugh Marston, Martien J. Kas & Brenda W. J. H. Penninx
Social dysfunction is one of the most common signs of major neuropsychiatric disorders. The Default Mode Network (DMN) is crucially implicated in both psychopathology and social dysfunction, although the transdiagnostic properties of social dysfunction remains unknown. As part of the pan-European PRISM (Psychiatric Ratings using Intermediate Stratified Markers) project, we explored cross-disorder impact of social dysfunction on DMN connectivity. We studied DMN intrinsic functional connectivity in relation to social dysfunction by applying Independent Component Analysis...

A meta-analytic database of randomised trials on psychotherapies for depression

Pim Cuijpers, Eirini Karyotaki, Soledad Quero, Blanca Pineda, Ricardo Munoz, Sascha Struijs, Jazmin Llamas & Caroline Figueroa
Background. The number of trials on psychotherapies for adult depression is very large and is quickly growing. Because of this large body of knowledge, it is important that the results of these studies are summarized and integrated in meta-analytic studies. More than a decade ago we developed a meta-analytic database of these trials, which was updated yearly through systematic literature searches. Recently, we developed a new version of this meta-analytic database, built on the systems...

The effectiveness of peer support for individuals with mental illness: systematic review and meta-analysis.

Dorien Smit, Pim Cuijpers, Jan Spijker, Janna Vrijsen, Bart Groeneweg & Clara Miguel
Despite the growth of initiatives based on peer support for people with mental health problems, the impact of such interventions remains unclear. Methodological issues and various focus of outcome measures and population, limits the generalizability of the scarce evidence regarding peer support for mental health problems (Cabassa, Camacho, Velez-Grau, & Stefancic, 2017; Lloyd-Evans et al., 2014). The overall aim of this project is to provide a comprehensive overview of current evidence and specific knowledge gaps...

W25: A Decolonized Approach to Scholarly Communication: Foundations, Challenges, and Perspectives in Practice and Research

Thomas hervé Mboa Nkoudou
Openness and the fast growth of information technology have contributed to reducing many injustices in knowledge diffusion. However, due to the immaterial nature of information, benign threats are still present in practices, research, infrastructure, and policies in academia. That means, once you are dealing with scholarly communication, whether you are a librarian, a researcher, a funder, a policymaker, or a software designer, what you are doing has impact everywhere across the world. But if you...

Marketa Ciharova, Heleen Riper, Ward van Breda, Khadicha Amarti, Christiaan Vis, Eirini Karyotaki, Pim Cuijpers & Mieke Schulte
Introduction: Common mental health disorders, more specifically mood and anxiety disorders, are highly prevalent and lead to decrease in general health, quality of life as well as social functioning, contributing substantially to the global burden of disease. Objective, real-time assessment of their active and passive signs, presented as expressions of sentiment in text, specific vocal features or facial expressions, may contribute to the timely recognition of and intervention for these disorders. Techniques allowing for such...

The interrelation between teacher-student relationship and working memory performance in primary school children

Simona Sankalaite, Jolien Dewandeleer, Dieter Baeyens & Mariette Huizinga
This project aims to examine the interrelation between teacher-student relationship and working memory development; we will test the uni- and bidirectional nature of the relationships between these constructs over time, both in typically developing controls (TDC) and children with a clinical profile (e.g., autism spectrum disorder) enrolled in the regular primary education. In addition, we aim to examine the characteristics of the teacher (e.g., age, years of experience) and child (e.g., socio-economic status, age, clinical...

Moral Emotion Perception - S1

Lei Fan, Joshua Tybur, Catherine Molho & Tom Kupfer
The current study aims to explore individuals' perception of moral emotions (i.e., anger & disgust) from an agent (a second or a third party) in a moral transgression event and further expectation of punishment behaviors (i.e., direct & indirect aggression), given a combined moral expression presentation (facial expression and non-verbal vocal expression) and abstract moral violation scenarios.

The effects of treatment after systematic screening for adults with depression: A meta-analysis

Ruiying Zhao, Eirini Karyotaki, Sascha Struijs & Pim Cuijpers
Depressive disorders are highly prevalent. Over 300 million people suffer from these disorders worldwide (Depression, WHO, 2017). Depression is a major contributor to the global burden of disease since it is associated with high mortality and morbidity (Friedrich, 2017; Vos et al., 2017), and it is associated with enormous human suffering and economic costs worldwide (Berto et al., 2000; Greenberg & Birnbaum, 2005). Moreover, at the individual level, depression brings harm in terms of one’s...

Honesty-Humility and Hazardous Organization Preferences/Perceptions

B. Wang, Reinout de Vries & Wendy Andrews
Because of experimenter error, the data collection of a previously preregistered study (10.17605/OSF.IO/PMHCW) has to be terminated only with data of Time 1. The planned sample size was 400 and we finally have collected 333 responses before realizing the error. We hereby preregister this analysis plan of the data in hand. New participants will be recruited for the original two-wave study that will be completed as originally planned.

Describing people we like and people we dislike in terms of HEXACO personality

Patrick Dunlop, Reinout de Vries & Anupama Bharadwaj
In this study, participants were asked to describe using written text, a person they liked and a person they disliked. Participants also completed a self-report HEXACO100 questionnaire, excluding the altruism items. The written descriptions were coded by three judges, who were asked to identify descriptions that included high levels or low levels of each of the six HEXACO personality dimensions. Judges also identified any descriptions that were particularly vitriolic. All judges were trained in a...

A Systematic Review of Predictors and Moderators of treatment outcome and symptom deterioration in internet- and mobile-based interventions for depression

Theresa Sextl, Anna-Carlotta Zarski, Maria Steinhoff, Harald Baumeister, Pim Cuijpers & David Ebert
Depression is a highly prevalent mental disorder and is associated with substantial impairment and reduced quality of life for affected individuals. Internet- and mobile-based interventions (IMIs) have shown to be a promising, cost-effective, and for therapists and patients acceptable way to treat this disorder. Their efficacy is well documented, so that IMIs have proven to be as effective as face-to-face therapy. However, not all patients treated with IMIs benefit to the same extent. Not only...

Relationship Interdependence Scale: Validity testing

Tiffany Matej Hrkalovic, Daniel Balliet & Francesca Righetti
The following study presents a continuation in the development of the multidimensional relationship interdependence scale. As a response to the first study, which was oriented on item reduction and testing the hypothesized seven-factor model of interdependence, as well as measurement invariance, this study will be oriented on testing the fit of an adjusted five-factor model of relationship interdependence with a reduced item pool. Additionally, the second aim of the study will be to test the...

Testing the effect of headline formulations on news selection

Nicolas Mattis, Wouter van Atteveldt & Luuk Lagerwerf
News selections in recommender systems are complex, multi-faceted processes that can be affected by a range of stable and situational factors. In this process, the presentation of individual news articles matters. This includes their position in a list of individual news headlines as well as the way they are formulated. Prior research into news selection recommender systems indicates that the positioning of an article has important implications for how likely an article is to be...
