Everything is cool when you're part of a team? The effects of outcome interdependence on appraisal, emotions, and performance under pressure.

Pressure is an innate feature of competition and stimulates cognitions and emotions that can both reduce and enhance performance. Similarly, teams are ubiquitous in sport and influence their members in various ways. Yet, we know little about the ways in which teams influence their members' responses to pressure, whether they are an added demand, inducing social indispensability and exacerbating the effects of pressure, or a resource, providing shared responsibility and buffering pressure effects. We conducted a field experiment across two samples of skilled handball players (N = 189) to test how outcome interdependence vs. independence influenced athletes' appraisals of task importance and coping prospects, anxiety and excitement, and penalty shooting performance under lower vs. higher situational pressure, and to what extent performance order and teammate skill moderated these effects. We found that pressure increased task importance and emotional intensity yet being part of a team or not made little difference. Descriptively, interdependence did attenuate the increase in anxiety under higher pressure and, if paired with skilled teammates, strengthen the increase in excitement. Yet, weak pressure manipulations, insensitive samples and measures require replication and prohibit conclusive interpretations regarding the influence of teams on members' responses to pressure.

Effect of COVID-19 Pandemic Lockdowns on Body Mass Index of Primary School Children from Different Socioeconomic Backgrounds.

BACKGROUND: Childhood obesity is associated with various health outcomes. Restrictive measures to contain the spread of the Coronavirus Disease 2019 (COVID-19) pandemic, like lockdowns and school closures, affected children's daily structure, physical activity, dietary habits, and sleep quality, possibly exacerbating risk factors for childhood obesity and higher body mass index (BMI) in children. Poor socioeconomic conditions may have led to relatively higher risk for elevated BMI levels following pandemic measures. In this study, the impact of measures related to the COVID-19 pandemic on the BMI of third graders was investigated regarding children's socioeconomic background (SEB). METHODS: Data from 41,728 children (8.84 ± 0.56 years, 20,431 female) were collected in the context of a cohort study. Children were tested either before the pandemic (preCOVID: Sept2017-March2020, n = 26,314), or following the first (postLDI: Aug2020-Dec2020, n = 6657) or second lockdown in Germany (postLDII: Aug2021-Jan2022, n = 8757). SEB was based on the official school type classification of the state of Berlin. Outcome was BMI standard deviation scores (SDS). RESULTS: Significant effects of Time and SEB revealed elevated BMIs in postLDI (M = 0.23, p = 0.011) and postLDII (M = 0.22, p = 0.011) compared to preCOVID (M = 0.17) cohorts and higher BMIs for children with lower SEB (b = - 0.13, p < 0.001). A significant Time × SEB interaction indicated that the effect of SEB on children's BMI increased in response to lockdowns, especially in postLDII (b = - 0.05, p = 0.006). Results suggest that the COVID-19-related measures lead to increased BMI in children, and that children of lower SEB were at particular risk for higher BMIs following lockdowns. CONCLUSIONS: These findings highlight the dependency of children's BMI on societal circumstances. Over the course of two lockdowns in Germany, children have experienced BMI increments, particularly in low socioeconomic areas. Authorities are called into action to counteract increasing rates of childhood weight by promoting physical activity of children and establishing related post-pandemic offers.

Narcissists' affective well-being: Associations of grandiose narcissism with state affect level and variability.

Whereas grandiose narcissism has generally been found to be related to adaptive affective experiences (i.e., positive affective states), many theoretical conceptualizations have emphasized its associations with characteristics of low affective well-being (i.e., unstable, highly variable affective states). Empirical research on the association of grandiose narcissism with the mean level of and variability in affective states has been inconclusive, as studies have differed considerably in their conceptualizations and measurement of narcissism and affect dynamics and have suffered from methodological limitations. Here, we offer conceptual explanations for previously inconsistent findings, derive diverging hypotheses about different aspects of narcissism and affective well-being, and investigate these hypotheses in two daily diary and three experience-sampling data sets (overall N = 2,125; total measurements = 116,336). As hypothesized, we found diverging associations between agentic and antagonistic aspects of narcissism with affect levels: Whereas narcissistic admiration was related to more pleasant affective states, narcissistic rivalry was related to less pleasant ones. We also obtained some support for diverging effects of admiration and rivalry on affect variability. However, these associations were largely reduced when we corrected for (squared) mean levels of affective valence and arousal. In combination, these findings suggest that only the agentic aspect of grandiose narcissism is conducive to affective well-being, whereas its antagonistic aspect negatively influences affective well-being. Moreover, the assumed associations of grandiose narcissism with volatile affectivity seem to rely heavily on mean-level effects and primarily manifest in experiences of more diverse affective states rather than stronger or more frequent affective fluctuations in general.

Psychological well-being in Europe after the outbreak of war in Ukraine.

The Russian invasion of Ukraine on February 24, 2022, has had devastating effects on the Ukrainian population and the global economy, environment, and political order. However, little is known about the psychological states surrounding the outbreak of war, particularly the mental well-being of individuals outside Ukraine. Here, we present a longitudinal experience-sampling study of a convenience sample from 17 European countries (total participants = 1,341, total assessments = 44,894, countries with >100 participants = 5) that allows us to track well-being levels across countries during the weeks surrounding the outbreak of war. Our data show a significant decline in well-being on the day of the Russian invasion. Recovery over the following weeks was associated with an individual's personality but was not statistically significantly associated with their age, gender, subjective social status, and political orientation. In general, well-being was lower on days when the war was more salient on social media. Our results demonstrate the need to consider the psychological implications of the Russo-Ukrainian war next to its humanitarian, economic, and ecological consequences.
