Good self-control has been linked to adaptive outcomes such as better health, cohesive personal relationships, success in the workplace and at school, less susceptibility crime addictions. In contrast, failure is maladaptive outcomes. Understanding mechanisms by which predicts behavior may assist promoting regulation A popular approach understanding strength or resource depletion model. Self-control conceptualized a limited that becomes depleted after period of exertion resulting failure....
Transactive goal dynamics (TGD) theory conceptualizes 2 or more interdependent people as 1 single self-regulating system. Six tenets describe the nature of interdependence, predict its emergence, when it will lead to positive outcomes during and after relationship, consequences for relationship. Both partners in a TGD system possess pursue self-oriented, partner-oriented, system-oriented goals, all these goals pursuits are interdependent. states that relationship partners' pursuit, affect...
Cross-sectional analyses have shown increased obesogenic behaviors and a potential for weight gain during COVID-19 related peak-lockdown (March-May 2020), but longitudinal data are lacking. This study assessed changes in body lifestyle the US adults pandemic.We used Qualtrics survey to collect self-reported on weight, dietary, physical activity, psychological variables (n = 727) (April/May) at post-lockdown (September/October). Peak-lockdown were categorized based magnitude of gained,...
During the initial phase of COVID-19 pandemic, U.S. conservative politicians and media downplayed risk both contracting effectiveness recommended health behaviors. Health behavior theories suggest perceived vulnerability to a threat health-protective behaviors determine motivation follow recommendations. Accordingly, we predicted that-as result politicization pandemic-politically Americans would be less likely enact In two longitudinal studies residents, political conservatism was inversely...
People in close relationships influence the health behavior of their significant others. Recent research has explored one form influence—social control—and produced results that suggest varying between social control, outcomes, and psychological well-being. For present article, we conducted a meta-analysis to compare three predominant models control. We observed measures control distinguish positive negative forms demonstrated stronger associations with outcomes than did general Furthermore,...

Understanding the determinants of COVID-19 vaccine uptake is important to inform policy decisions and plan vaccination campaigns. The aims this research were to: (1) explore individual- country-level intentions be vaccinated against SARS-CoV-2, (2) examine worldwide variation in intentions. This cross-sectional online survey was conducted during first wave pandemic, involving 6697 respondents across 20 countries.

Abstract The present paper examines longitudinally how subjective perceptions about COVID-19, one’s community, and the government predict adherence to public health measures reduce spread of virus. Using an international survey ( N = 3040), we test infection risk perception, trust in governmental response communications conspiracy beliefs, social norms on distancing, tightness culture, community punishment various containment-related attitudes behavior. Autoregressive analyses indicate that,...
We investigated how power dynamics in close relationships influence the tendency to devote resources pursuit of goals valued by relationship partners, hypothesizing that low (vs. high) would lead individuals center their individual goal around partners. study 2 related phenomena: partner prioritization, whereby pursue on behalf and contagion, identify adopt as own pursues. tested our ideas 5 studies employed diverse research methods, including lab experiments dyadic romantic multiple types...
Abstract Although consumers put substantial effort toward their appearance, engaging in beauty work is often seen as inauthentic, posing challenges for companies that increasingly rely on social media-driven product promotion where authenticity perceptions are consequential. This article draws existentialist notions of (wherein the true self created rather than innate) to explore how framing self-expression alters others’ and, turn, marketing outcomes.

National representative samples were collected from 24 countries (N = 25,435). The main predictors (1) perceived risk contract coronavirus, (2) suffer economic losses due (3) their interaction effect. Individual country-level variables added as covariates in multilevel regression models. We examined...
Objectives: Cross-sectional reports on weight gain during the COVID-19 shelter-at-home have raised concerns for increases as pandemic continues. We examined behaviors that impact energy intake and/or expenditure among adults in United States shelter-at-home. Methods: data (N=1779; April 24 – May4, 2020) were collected demographics, diet, physical activity, sleep, and food purchasing behaviors.

Abstract 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, has typically examined only a small number one, of, national contexts. Such approaches make it difficult to examine relative importance predictors, risk overlooking some potentially relevant variables altogether. To overcome this limitation, present study used machine learning...
The psychological literature on self-control has illustrated the many benefits experienced by people with high self-control, who are more successful both personally and interpersonally. In current research, we explore possibility that having also may have some interpersonal costs, leading individuals to become burdened others' reliance. Studies 1 2, examined effects of actors' observers' performance expectations found observers had higher for actors (vs. low) self-control. Study 3, tested...

Our study aimed identify important predictors this behaviors. Whereas social and health psychological theories suggest limited predictors, machine-learning analyses can correlates from larger pool candidate predictors. We used random forests rank 115 behavior in 56,072 participants across 28 countries, administered March May...

We also tested whether these paths are mediated by general well-being, moderated collective disempowerment, i.e.,...
