Psychological treatment of chronic and treatment-resistant depression: A meta-analysis

Pim Cuijpers
Chronic depression and treatment-resistant depression are highly important from a clinical perspective. Despite this clinical relevance, relatively few trials have examined the effects of psychological interventions and only a limited number of meta-analyses of these trials have been conducted. No recent meta-analysis has focused on the effects of psychotherapies for chronic and treatment-resistant depression compared with control conditions (care-as-usual, waitlist, pill placebo, others). We decided to conduct a new meta-analysis of psychotherapies for chronic and...

Gossip About COVID-19 Infection versus Recovery and Social Distancing Norm Violation versus Adherence

Terence Dores Cruz
This project concerns a scenario study whereparticipants are asked to imagine a situation in which they receive gossip from a friend about an acquaintance of their friend, who they do not know. The gossip varies on two dimensions in 3x3 full-factorial design. First, the gossip describes the acquaintance as either having recovered from infection with the Coronavirus, as currently infected (symptomatic) with the Coronavirus, or provides no information on infection with the Coronavirus. Secondly, the...

Response rates in control conditions of psychotherapies for depression: A meta-analysis of waiting lists, care-as-usual and pill placebo

Pim Cuijpers, Eirini Karyotaki, Hisashi Noma & Toshi Furukawa
Research on response and remission rates in control condition of psychotherapies is scarce, with most reviews including only a small number of studies and mixing different types of research. Research on this subject is, however, important for several reasons. First, it can give indications for the response and remission rates of ‘usual care’, because this is one of the most important control conditions in psychotherapy trials, and thus give a benchmark for what usual care...

Internalizing/Externalizing Behaviors Data Harmonization for CAMPOS

Or Dagan, Carlo Schuengel, Marije Verhage & The Collaboration Synthesis
This document details the harmonization method for evaluating internalizing and externalizing behavior outcomes in the pre-registered individual participant data (IPD) meta-analysis on the attachment network to multiple caregivers (https://osf.io/a3qs9).

Psychological treatment of perinatal depression: A meta-analysis

Pim Cuijpers
Depression during pregnancy and after the birth of a child is highly prevalent and results in a considerable reduction in quality of life, social functioning (Drury et al., 2016), maternal functioning (O’Hara & McCabe, 2013). It can also have severe consequences in children, including poor cognitive, emotional, behavioral, and physical outcomes (Goodman et al., 2011; O’Hara & McCabe, 2013). Although several meta-analyses have examined the effects of psychological treatments of perinatal depression, they have all...

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

Pim Cuijpers, Eirini Karyotaki, Marketa Ciharova, Hisashi Noma, Soledad Quero, Matthijs Oud, Ioannis Michopoulos, Georgia Salanti, Edoardo Ostinelli, Sanae Kishimoto & Akira Onishi
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...

Which characteristics of autism predict treatment choice, frequency, duration and intensity?

Elisa Back, Sander Begeer & Kim Jonkman
Autism is a heterogeneous condition and treatment options vary. This study will investigate whether differing characteristics/profiles of children with autism are linked to diversity in treatment choice. Research suggests that the factors that influence parents’ decision-making about treatment change over time, starting when the child is first diagnosed (Edwards et al., 2018). The use of most treatments decrease with age, while psychotropic medication increases with age (Mire et al., 2015). Children with more severe autism...

Effectiveness of Internet- and Mobile-Based Cognitive Behavioral Therapy to Reduce Suicidal Ideation and Behaviours: Protocol for a Systematic Review and Meta-Analysis of Individual Participant Data

Rebekka Büscher, Marie Beisemann, Philipp Doebler, Lena Steubl, Matthias Domhardt, Pim Cuijpers, Ad Kerkhof & Lasse Sander
Suicidal ideation and behavior are a major mental health problem worldwide. Many individuals at risk of suicide do not receive treatment. In recent years, low-threshold internet- and mobile-based interventions for suicidality have been developed. Current meta-analyses suggest that they might reduce suicidal ideation. However, they found small effect sizes and it remains unclear whether specific subgroups experience beneficial or harmful effects. Therefore, we will conduct an individual patient data meta-analysis (IPD-MA) to establish the effectiveness...

Testing child reactive temperament as a moderator in attachment transmission

Marije Verhage, Sheri Madigan, Carlo Schuengel, Pasco Fearon, Marinus van IJzendoorn, Marian Bakermans-Kranenburg, Glenn Roisman, Mirjam Oosterman, Howard Steele, Annie Bernier, Kazuko Behrens, Jude Cassidy, Karin Ensink, George Tarabulsy, Ora Aviezer & Mette Vaever
Ever since Main et al. (1985)’s discovery that parents’ attachment representations are associated with parent-child attachment, the intergenerational transmission of attachment has intrigued researchers across the globe. Research has focused on sensitive caregiver behavior as the mediating mechanism through which a parent’s attachment state of mind expresses itself leading to child-parent attachment, but meta-analytic evidence showed that sensitive responsiveness explained only 25% of the intergenerational association (Van IJzendoorn, 1995; Verhage et al., 2016). Solving this...

Scalable Psychological Interventions for Syrian Refugees in Europe and the Middle East: STRENGTHS Study Protocol for a Prospective Individual Participant Data Meta-Analysis

Anne de Graaff, Pim Cuijpers & Marit Sijbrandij
The World Health Organization (WHO) developed several scalable psychological interventions delivered by trained and supervised non-specialists to reduce psychological distress in communities affected by adversity (Dawson et al., 2015). These interventions are potentially cost-effective solutions for settings where access to mental health services is low. Examples of such interventions are Problem Management Plus (PM+) and Step-by-Step (SbS). Prior research on PM+ in violence-affected settings in Kenya and Pakistan showed that the intervention is related to...

Individual differences in the effects of Task-Shifted Psychotherapy for Depression: Study Protocol of An Individual Patient Data Meta-analysis

Eirini Karyotaki, Pim Cuijpers, Ricardo Araya, Yagmur Amanvermez, Ronald Kessler & Vikram Patel
More than 320 million people suffer from depression worldwide1. The enormous treatment gap calls for innovative solutions in the delivery of mental-health care. In low-resource settings, a “task-shifting” approach may be beneficial in using human resources more efficiently2. Task shifting is the strategy of delegating care tasks to health workers who have fewer qualifications and shorter training than mental healthcare experts (e.g., psychiatrists, clinical psychologists or nurses)3. Nevertheless, relatively little is known about individual patient...

Boredom in Relationships and Its Effects on Personal Well-being

Yang Xu, Rachele Mazzini, Xinrui Li & Francesca Righetti
According to the self-expansion model, people are motivated to acquire new resources and experiences, relationships are one good source for this process (Aron, Lewandowski, Mashek, & Aron, 2013) However, when the expansion period decelerates, relational boredom would occur (Aron & Aron, 1986) but little is known about the influence of relational boredom on close relationships. In this study, we intend to clarify the link between relational boredom and personal well-being. In addition, we will manipulate...

Unraveling Zechstein 3 Anhydrite Structuration and possible implications for Geo-Drilling Hazards

Ward Teertstra & Guido Hoetz
VU Amsterdam, Netherlands (1); EBN, Netherlands, The (2) Anhydrites Carbonates of the Leine formation, the third evaporitic cycle of the Zechstein group, are widely distributed in the Southern Permian basin. These strata are often drilled through by wells targeting underlying Rotliegend gas prospects. The ZEZ3C/A members constitute brittle rocks sandwiched by the ductile halites from the underlying ZEZ2H and the overlying ZEZ3H. The brittle sheet is frequently rifted (boudinage) and the resulting fragments are often...

Belief in contradictory conspiracy theories Study 2

Jan-Willem van Prooijen, Nicole Mulas, Laura Mausolf, Shayda Shwan & Iris Guhring
Wood et al. (2012) found that belief in one conspiracy theory is positively correlated with belief in a second contradictory conspiracy theory. For instance, participants were asked to what degree they believed Princess Diana was murdered and, alternatively, faked her own death. Based on this positive correlation, they conclude that those who believe in one conspiracy theory are more likely to also believe a contradictory conspiracy theory. However: participants who disagree with both conspiracy theories...

Boredom on Relationship Satisfaction

Yang Xu, Rachele Mazzini, Francesca Righetti & Xinrui Li
According to the self-expansion model, people are motivated to acquire new resources and experiences, relationships are one good source for this process (Aron, Lewandowski, Mashek, & Aron, 2013) However, when the expansion period decelerates, relational boredom would occur (Aron & Aron, 1986) but little is known about the influence of relational boredom on close relationships. In this study, we will examine the relationship between relational boredom and negative emotional outcomes such as depression and life...
