Gender inequality and cultural values in explaining gender differences in positive and negative emotions: A comparison of 24 countries during the Covid-19 pandemic
The coronavirus pandemic posed a major challenge to mental health. Existing evidence shows that COVID-19 is related to poor emotional well-being, particularly among women. However, most work on the subject uses single-country samples, limiting the ability to generalize the disparity or explain it as a function of societal variables. The present study investigates the expression of positive and negative emotions during the pandemic as a function o…
Need Fulfillment During Intergroup Contact: Three Experience Sampling Studies
One challenge of modern intergroup contact research has been the question of when and why an interaction is perceived as positive and improves intergroup relations. We propose to consider the perceived fulfillment of the situationally most relevant need. We conducted three intensive longitudinal studies with recent migrants to capture their interactions with the majority out-group ( N measurements = 10,297; N participants = 207). The situational …
A Gentle Introduction and Application of Feature-Based Clustering with Psychological Time Series
Psychological researchers and practitioners collect increasingly complex time series data aimed at identifying differences between the developments of participants or patients. Past research has proposed a number of dynamic measures that describe meaningful developmental patterns for psychological data (e.g., instability, inertia, linear trend). Yet, commonly used clustering approaches are often not able to include these meaningful measures (e.g.…
Just World Beliefs in a Time of Crisis: Cross-Lagged Panel and Moderating Cross-National Effects on Mental Health and Well-Being Outcomes
Belief in a just world (BJW) is well established as a coping resource, particularly for those times when the world is experienced as uncertain, unpredictable, and uncontrollable. The early days of the COVID-19 pandemic was such a time, and therefore provided an opportunity to test the boundary conditions of BJW theorizing. Here, we make a new methodological contribution, testing (a) cross-lagged panel effects of BJW on mental health and well-bein…
The Precarity of Progress: Implications of a Shifting Gendered Division of Labor for Relationships and Well-Being as a Function of Country-Level Gender Equality
The onset of the COVID-19 pandemic saw a shift toward a more traditional division of labor–one where women took greater responsibility for household tasks and childcare than men. We tested whether this regressive shift was more acutely perceived and experienced by women in countries with greater gender equality. Cross-cultural longitudinal survey data for women and men ( N = 10,238) was collected weekly during the first few months of the pandemic…
Passion for guns and beliefs in a dangerous world: An examination of defensive gun ownership
This research examines the notion of defensive gun ownership using the Dualistic Model of Passion. We hypothesized that an obsessive (vs. harmonious) passion for guns would be associated with a belief in a dangerous world (BDW). We expected this relationship to intensify in threatening contexts, leading to a more expansive view on defensive gun ownership. We tested this hypothesis across three threat contexts: a gun‐control message (Study 1, N = …
Intentions to be Vaccinated Against Covid-19: The Role of Prosociality and Conspiracy Beliefs across 20 Countries
Understanding the determinants of COVID-19 vaccine uptake is important to inform policy decisions and plan vaccination campaigns. The aims of this research were to: (1) explore the individual- and country-level determinants of intentions to be vaccinated against SARS-CoV-2, and (2) examine worldwide variation in vaccination intentions. This cross-sectional online survey was conducted during the first wave of the pandemic, involving 6697 responden…
The role of values in coping with health and economic threats of Covid-19
61,490) suggest that health and economic threats of COVID-19 evoke different values, with implications for controlling and coping with the pandemic. Specifically, health threats predicted prioritization of communal values related to caring for others and belonging, whereas economic threats predicted prioritization of agentic values focused on competition and achievement. Concurrently and over time, prioritizing communal values over agentic values…
Impact of National Pandemic Lockdowns on Perceived Threat of Immigrants: A Natural Quasi-Experiment Across 23 Countries
Xenophobia and anti-immigrant attacks rose during the COVID-19 pandemic, yet this may not be solely due to the disease threat. According to theories of frustration and scapegoating, situational obstructions and deprivation can motivate prejudice against outgroups. Using a global natural quasi-experimental design, this study tests whether the restrictiveness of national lockdowns can explain higher individual-level perceptions of immigrant threat.…
Pandemic boredom: Little evidence that lockdown-related boredom affects risky public health behaviors across 116 countries
Some public officials have expressed concern that policies mandating collective public health behaviors (e.g., national/regional "lockdown") may result in behavioral fatigue that ultimately renders such policies ineffective. Boredom, specifically, has been singled out as one potential risk factor for noncompliance. We examined whether there was empirical evidence to support this concern during the COVID-19 pandemic in a large cross-national sampl…
Identifying important individual‐ and country‐level predictors of conspiracy theorizing: A machine learning analysis
Psychological research on the predictors of conspiracy theorizing—explaining important social and political events or circumstances as secret plots by malevolent groups—has flourished in recent years. However, research has typically examined only a small number of predictors in one, or a small number of, national contexts. Such approaches make it difficult to examine the relative importance of predictors, and risk overlooking some potentially rel…
Lockdown Lives: A Longitudinal Study of Inter-Relationships Among Feelings of Loneliness, Social Contacts, and Solidarity During the Covid-19 Lockdown in Early 2020
We examine how social contacts and feelings of solidarity shape experiences of loneliness during the COVID-19 lockdown in early 2020. From the PsyCorona database, we obtained longitudinal data from 23 countries, collected between March and May 2020. The results demonstrated that although online contacts help to reduce feelings of loneliness, people who feel more lonely are less likely to use that strategy. Solidarity played only a small role in s…
The rise and fall of job insecurity during a pandemic: The role of habitual coping
Crises like the COVID-19 pandemic can trigger concerns about loss of employment and changes in work conditions, and thereby increase job insecurity. Yet, little is known about how perceived job insecurity subsequently unfolds over time and how individual differences in habitual coping moderate such a trajectory. Using longitudinal data from 899 US-based participants across 5 waves (March to June 2020), we investigated the trajectory of job insecu…
Associations of risk perception of Covid-19 with emotion and mental health during the pandemic
Cooperation and Trust Across Societies During the Covid-19 Pandemic
Cross-societal differences in cooperation and trust among strangers in the provision of public goods may be key to understanding how societies are managing the COVID-19 pandemic. We report a survey conducted across 41 societies between March and May 2020 ( N = 34,526), and test pre-registered hypotheses about how cross-societal differences in cooperation and trust relate to prosocial COVID-19 responses (e.g., social distancing), stringency of pol…
We are all in the same boat’: How societal discontent affects intention to help during the Covid ‐19 pandemic
The coronavirus disease 2019 (COVID-19) pandemic has caused a global health crisis. Consequently, many countries have adopted restrictive measures that caused a substantial change in society. Within this framework, it is reasonable to suppose that a sentiment of societal discontent, defined as generalized concern about the precarious state of society, has arisen. Literature shows that collectively experienced situations can motivate people to hel…
Frustration-affirmation? Thwarted goals motivate compliance with social norms for violence and nonviolence
whereby thwarted goals increase compliance with perceived norms for behavior, which can increase endorsement of violent means such as guns and war, but also nonviolent charitable actions. (PsycInfo Database Record (c) 2020 APA, all rights reserved)
Mass shootings and the salience of guns as means of compensation for thwarted goals
Between 2016 and 2017, Americans suffered 3 of the deadliest mass shootings in modern history by a lone gunman: the Orlando nightclub shooting, the Las Vegas strip shooting, and the Texas church shooting. We studied American gun owners in the wakes of these tragedies, theorizing that a byproduct of the salience of mass shootings is to increase the salience of guns as means of individual empowerment and significance. We hypothesized that this incr…
