Parametric g-formula for Testing Time-Varying Causal Effects: What It Is, Why It Matters, and How to Implement It in Lavaan.

Psychologists leverage longitudinal designs to examine the causal effects of a focal predictor (i.e., treatment or exposure) over time.

Person-specific priorities in solitude.

Objective: People value solitude in varying degrees. Theories and studies suggest that people's appreciation of solitude varies considerably across persons (e.g.

Cynical people desire power but rarely acquire it: Exploring the role of cynicism in leadership attainment.

Do cynical individuals have a stronger desire for power and are they more likely to acquire power at work? The negative consequences of cynicism-for cynics themselves and the people around them-render the examination of these questions particularly important. We first examined the role of cynicism in power motives. Results showed that more cynical individuals have a greater desire for power to avoid exploitation by others (and less so to exploit others; Study 1) and score higher on dominance (but not prestige or leadership) motives (Study 2).

Understated gender disparities due to outcome-dependent selection: Commentary on Mackelprang et al. (2023).

What is the gender gap in invited publications in high-impact psychology journals? To answer this critical question, Mackelprang et al. (2023) examined invited publications in five high-impact psychology journals. They first calculated the share of women among authors of the invited publications (35.

Do targets of ostracism truthfully communicate their emotional reactions to sources?

Ostracism triggers negative emotions such as sadness, anger, and hurt feelings. Do targets of ostracism truthfully share their emotions with the sources of ostracism? Drawing on past research on social-functional accounts of emotions and interpersonal emotion regulation, we investigated the possibility that targets may misrepresent their emotions (i.e.

Alone in a Crowd: Is Social Contact Associated with Less Psychological Pain of Loneliness in Everyday Life?

Unlabelled: People are often advised to engage in social contact to cope with the experience of loneliness and improve well-being. But are the moments of loneliness actually more bearable when spent in other people's company? In this research, we proposed and tested two conflicting theoretical accounts regarding the role of social contact: social contact is associated with a stronger (the amplifying account) or with a weaker (the buffering account) negative effect of loneliness on psychological well-being. Analyses of three datasets collected using ecological momentary assessments ( = 3,035) revealed that the negative association between loneliness and well-being was stronger when participants were with others than alone, consistent with the amplifying account.

Estimating time-varying treatment effects in longitudinal studies.

Longitudinal study designs are frequently used to investigate the effects of a naturally observed predictor (treatment) on an outcome over time. Because the treatment at each time point or wave is not randomly assigned, valid inferences of its causal effects require adjusting for covariates that confound each treatment-outcome association. But adjusting for covariates which are inevitably time-varying is fraught with difficulties.

Data-driven covariate selection for confounding adjustment by focusing on the stability of the effect estimator.

Valid inference of cause-and-effect relations in observational studies necessitates adjusting for common causes of the focal predictor (i.e., treatment) and the outcome.

The Psychological Science Accelerator's COVID-19 rapid-response dataset.

In response to the COVID-19 pandemic, the Psychological Science Accelerator coordinated three large-scale psychological studies to examine the effects of loss-gain framing, cognitive reappraisals, and autonomy framing manipulations on behavioral intentions and affective measures. The data collected (April to October 2020) included specific measures for each experimental study, a general questionnaire examining health prevention behaviors and COVID-19 experience, geographical and cultural context characterization, and demographic information for each participant. Each participant started the study with the same general questions and then was randomized to complete either one longer experiment or two shorter experiments.

Adjusting for Baseline Measurements of the Mediators and Outcome as a First Step Toward Eliminating Confounding Biases in Mediation Analysis.

Mediation analysis prevails for researchers probing the etiological mechanisms through which treatment affects an outcome. A central challenge of mediation analysis is justifying sufficient baseline covariates that meet the causal assumption of no unmeasured confounding. But current practices routinely overlook this assumption.

Does dispositional preference for solitude predict better psychological outcomes during times of social distancing? Beliefs and reality.

Objective: People value solitude for themselves. Yet little is known about how people perceive dispositional preference for solitude in others. Does dispositional preference for solitude represent a protective factor from psychological distress during times of social distancing? And do laypeople have accurate beliefs about the role of preference for solitude?

Method: To answer these questions, we conducted four studies (three preregistered, N  = 1418) at the early and a later stage of the COVID-19 pandemic using experimental, longitudinal, and experience sampling designs.

Intensity, intent, and ambiguity: Appraisals of workplace ostracism and coping responses.

Using both correlational and experimental designs across four studies (N = 1251 working individuals), the current project aimed to contribute to the understanding of workplace ostracism by studying two research questions. First, we tested whether the subjective experience of targets reflects the current theorizing of ostracism. Second, drawing from the transactional theory of stress and coping, we investigated whether this subjective experience impacts targets' coping responses.

Does a pandemic context attenuate people's negative perception and meta-perception of solitude?

Solitude-the state of being alone without social interactions-is a common experience in everyday life. Despite that spending time alone can be enjoyable and functional, solitude is often stigmatised: People who engage in solitary activities are perceived negatively (negative perceptions of solitude) and anticipate a negative judgement from others (negative meta-perceptions of solitude). Using the COVID-19 pandemic as a backdrop, we examined whether a pandemic context, in which solitary behaviours were easily attributable to external reasons, would reduce people's negative perceptions and meta-perceptions of solitude.

In COVID-19 Health Messaging, Loss Framing Increases Anxiety with Little-to-No Concomitant Benefits: Experimental Evidence from 84 Countries.

The COVID-19 pandemic (and its aftermath) highlights a critical need to communicate health information effectively to the global public. Given that subtle differences in information framing can have meaningful effects on behavior, behavioral science research highlights a pressing question: Is it more effective to frame COVID-19 health messages in terms of potential losses (e.g.

Do cues of infectious disease shape people's affective responses to social exclusion?

Social exclusion triggers aversive reactions (e.g., increased negative affect), but being excluded may bring substantial benefits by reducing pathogen exposure associated with social interactions.

The Association Between Dispositional Mindfulness and Need Threat Following Ostracism in Spanish Adolescents: The Moderating Role of Age.

Background: Ostracism -being ignored and excluded- entails risks for adolescent mental health. Less is known about the factors that are negatively associated with the adverse consequences of ostracism. This study explored the association between dispositional mindfulness and need threat following social exclusion using the Cyberball paradigm.

Nonlinear effect of social interaction quantity on psychological well-being: Diminishing returns or inverted U?

Social contact is an important ingredient of a happy and satisfying life. But is more social contact necessarily better? Although it is well-established that increasing the quantity of social interactions on the low end of its spectrum promotes psychological well-being, the effect of interaction quantity on the high end remains largely unexplored. We propose that the effect of interaction quantity is nonlinear; specifically, at high levels of interaction quantity, its positive effects may be reduced (Diminishing Returns Hypothesis) or even reversed (Inverted U Hypothesis).

A multi-country test of brief reappraisal interventions on emotions during the COVID-19 pandemic.

The COVID-19 pandemic has increased negative emotions and decreased positive emotions globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce negative emotions and increase positive emotions, we tested the effectiveness of reappraisal, an emotion-regulation strategy that modifies how one thinks about a situation.

Low Self-Control: A Hidden Cause of Loneliness?

Loneliness has been associated with multiple negative outcomes. But what contributes to loneliness in the first place? Drawing from the literature on the importance of self-regulatory ability for successful social functioning, the present research explored the role of low self-control as a factor leading to loneliness. A set of four studies (and three additional studies in Supplementary Online Materials) using cross-sectional, experimental, daily diary, and experience sampling methods showed that lower self-control is associated with higher loneliness at both trait and state levels.

To which world regions does the valence-dominance model of social perception apply?

Over the past 10 years, Oosterhof and Todorov's valence-dominance model has emerged as the most prominent account of how people evaluate faces on social dimensions. In this model, two dimensions (valence and dominance) underpin social judgements of faces. Because this model has primarily been developed and tested in Western regions, it is unclear whether these findings apply to other regions.

Leaving the Loners Alone: Dispositional Preference for Solitude Evokes Ostracism.

What are the interpersonal consequences of seeking solitude? Leading theories in developmental research have proposed that having a general preference for solitude may incur significant interpersonal costs, but empirical studies are still lacking. In five studies (total = 1,823), we tested whether target individuals with a higher preference for solitude were at greater risk for ostracism, a common, yet extremely negative, experience. In studies using self-reported experiences (Study 1) and perceptions of others' experiences (Study 2), individuals with a stronger preference for solitude were more likely to experience ostracism.

Seeking Solitude After Being Ostracized: A Replication and Beyond.

Individuals may respond to ostracism by either behaving prosocially or antisocially. A recent paper provides evidence for a third response: solitude seeking, suggesting that ostracized individuals may ironically engage in self-perpetuating behaviors which exacerbate social isolation. To examine this counterintuitive response to ostracism, we conceptually replicated the original paper in three studies ( = 1,118).
