Since the coronavirus (SARS-CoV-2) pandemic began, large amounts of (mis)information have been disseminated worldwide. We conducted an online survey in Switzerland (N = 1,129) in April 2021 to ask respondents which information has received too little attention in public discourse, which measures help containing coronavirus infection and Covid-19, and about subjectively perceived Covid-19 misinformation. Content analysis of the open answers revealed that vaccination and its potential side effects, aspects related to political measures, psychological and social aspects, as well as science and research topics deserved more attention in the eyes of the respondents, mostly from politics or media. The most frequently mentioned effective measures were social distancing, wearing masks, general hygiene, and vaccination. Notably, the number of measures mentioned was related to the degree to which the pandemic affected individuals subjectively, trust in public institutions, and their individual level of science-related populism. Swiss residents with less trust in public institutions and who consume less news media on Covid-19 are more likely to believe misinformation on (in)effective measures against the virus. Most respondents encountered Covid-19 misinformation and could name examples, including sources. Education and information use affect the frequency of subjectively encountered misinformation. More highly educated people can name more misinformation instances encountered than less educated people.

Nation-states are seen as reasonable candidates to whom to assign remedial responsibilities for climate change harms. A natural question arises: Based on what justification should these responsibilities be assigned to states? Three prominent principles have been proposed: the “Polluter pays,” the “Beneficiary pays,” and the “Ability to pay.” However, each principle faces important objections when considered in isolation. Building on David Miller's multi-principle theory of remedial responsibility, I propose and justify an account of remedial responsibility for the case of climate change. I complement the account with a guiding algorithm that arranges these (and more) principles in a systematic way to make remedial responsibilities for climate change harms applicable. This guiding algorithm resolves the objections that arise when the principles are applied in isolation.

Caused by perceived norm violations, online firestorms confront organizations with large volumes of hostile-emotional comments on public social media leading to a damage to reputation or the cancellation of products and projects. Relying on social norm theory we analyze how people express perceived norm violations in their online comments and how this relates to their use of hostile-emotional online sanctions. We distinguish negative externalities; propriety judgements; excess of zeal, which combines negative externalities with propriety judgements; and no justification, meaning no speculations about why norm violations occurred, as four types of motive for hostile verbal expression. Using hostile-emotional sanctioning is differently associated with these motives: (1) weak association with negative externalities to maintain credibility; (2) moderate association with propriety judgements as a result of altruistic punishments; (3) moderate association with no justification, triggered by arousal; and (4) strong association with an excess of zeal because norm enforcers believe that a latent group exists which rewards them with positive sanctions for working toward the common goal and punishes them with negative sanctions for shirking. We analyze one specific online protest signed by 305,122 people that led to a massive hostile-emotional firestorm against an organization. We find that 37% of the 44,173 individuals who additionally commented their protest participation were hostile and/or emotional. As predicted, we find that compared to the other motives, the excess of zeal is most likely to motivate hostile-emotional sanctions. Overall, our theory and findings explain why most online firestorms are hard to stop: with an excess of zeal, a latent group of norm enforcers must be appeased.

The relations between self and others are fluid and constantly changing but exert a profound influence on our identity and emotional experiences. Indeed, human emotions are frequently and intensely social, and the people with whom we interact can alter our momentary mood. But does emotional "contagion" extend over prolonged periods of hours to days, and, if so, how does it propagate through interconnected groups? Answering this question is empirically challenging, because mood similarity in connected individuals can arise through multiple mechanisms (social influence, social selection, and shared external causation), making causal inferences hard to draw. We address this challenge using temporally high-resolution, longitudinal data from 2 independent, bounded social networks during periods of high communal activity and low external contact. Adolescent study participants (N = 79) completed daily mood (n = 4,724) and social interaction (n = 1,775) ratings during residential performance tours of classical music lasting 5 to 7 days. Analyses using statistical network models show that in both networks, adolescent musicians became reciprocally more similar in mood to their interaction partners. The observed contagion effect was greater for negative than for positive mood. That is, although one may catch a friend's bad mood, the friend may feel less negative in the process. These results suggest a mechanism for emotional buffering and the cost of social support. We found no evidence for social selection based on mood. Indeed, participants were remarkably tolerant of their peers' mood fluctuations and showed no evidence of altering their patterns of social interaction accordingly.

The distal relationship between risk factors in childhood and subsequent dating violence in late adolescence has not often been explored using longitudinal data. This study aims to shed light on the problem of dating violence by examining children’s backgrounds at age 7 and the link to the future involvement in dating violence at age 17 using the first and seventh waves of the Zurich Project on the Social Development from Childhood to Adulthood (z-proso, n = 644). The sample consists of 644 multiethnic adolescents (57.14% female, M = 17.47, SD = 0.37), mainly Swiss-born (90%), though more than half of their parents (60%) were born in another country. A latent class analysis was applied to identify three different profiles (a) zero (or minimal) involvement in teen dating violence, (b) perpetrators/victims of controlling behaviors, and (c) perpetrators/victims of controlling behaviors and of physical violence. Participants who were corporally punished and/or victims of bullying at age 7 were significantly more likely to belong to the controlling and physical violence profile than children in the non-violent class. These results suggest a certain chronicity of the effects of violent experiences in early childhood on the patterns of romantic relationships at 17 years old.

Introduction: We investigated the longitudinal course of self-, other-, and dual-harm in adolescents, focusing on the infliction of physical injury on oneself, another person, or both parties, respectively. We examined the within-person transitions between these types of harm and whether relationships with peers and teachers predict individual harm trajectories. Methods: We used community-representative longitudinal data (N = 1,482; 52% male; 50% both parents born abroad). The participants self-reported self- and other-harm at 13, 15, 17, and 20 years. We assigned them to groups with self-, other-, dual- or no harm at specific assessments. Bullying victimization and relationship quality with classmates and teachers were assessed at 13 and 17. We estimated transition probabilities between the harm groups using latent Markov chain models. Results: At age 13, 3% of the sample engaged in dual-harm, 10% in self-harm only, and 7% in other-harm only. These percentages decreased in late adolescence. Initial dual-harm was often followed by sex-specific single-harm: most of the female participants transitioned to self-harm, and male participants to other-harm. Those in the initial dual-harm group were less likely to stop harming than those in the initial single-harm groups (p < 0.05). Adverse relationship experiences generally predicted harm. A positive teacher-student bond was associated with the cessation of single-harm. Conclusion: Single- and dual-harm in the form of physical injury typically emerge by mid-adolescence. After this point, adolescents commonly maintain harm, especially those who have presented with dual-harm. Helping adolescents cope with adverse relationship experiences and creating opportunities for positive relationship experiences could address these harmful behaviors.

We conducted a large number of controlled continuous double auction experiments to reproduce and stress-test the phenomenon of convergence to competitive equilibrium under private information with decentralized trading feedback. Our main finding is that across a total of 104 markets (involving over 1,700 subjects), convergence occurs after a handful of trading periods. Initially, however, there is an inherent asymmetry that favors buyers, typically resulting in prices below equilibrium levels. Analysis of over 80,000 observations of individual bids and asks helps identify empirical ingredients contributing to the observed phenomena including higher levels of aggressiveness initially among buyers than sellers., International Economic Review, ISSN:0020-6598, ISSN:1468-2354

Previous research has suggested that bullying victimization is associated with higher suicidal risk among young people; however, the mechanisms underlying this relation have not been well examined. The current study aimed to illuminate the developmental links between bullying victimization and suicidal ideation by examining the mediating roles of depressive symptoms, anxiety symptoms, and substance use. The study sample consisted of n = 1465 participants (51.7% male) from the normative z-proso study. Using random intercept cross-lagged panel models and three waves of longitudinal data (ages 15, 17, and 20), the hypothesized mediation effects at the within-person level were tested while partialling out between-person confounds. The results suggested that, at the within-person level, bullying victimization did not predict subsequent suicidal ideation via depressive symptoms, anxiety symptoms, or substance use. However, age 15 bullying victimization predicted within-person increases in age 17 depressive symptoms and suicidal ideation. In addition, depressive symptoms at age 15 and tobacco and cannabis use at age 17 were associated with within-person increases in bullying victimization at ages 17 and 20, respectively. The results also indicated that cannabis use and suicidal ideation were positively and reciprocally related over time. Future studies collecting data at multiple timescales are needed to understand proximal and longer-term mechanisms underlying the relation between bullying victimization and suicidality.

Are upper-class individuals more inclined to violate rules? Using behavioural data, recent studies have challenged the traditional assumption of upper social class members being less rule violating, while other studies find no or opposite effects. We bring together behavioural decision-making games with traditional survey measures in a unique setup to re-evaluate the proposed relation between social class and rule violations, distinguishing between the economic and the psychological components of social class. Drawing from a cohort of 750 Swiss adults, we investigate how the conditions they were born in (social origins) and the current financial resources (disposable income) affect self-reported and behaviourally measured rule violations in the lab. Interestingly, our findings show that disposable income impacts the behaviour of individuals conditional upon their social origins. For people with upper social origins an increase in disposable income leads to more rule violations than for people with lower social origins. Additional analyses show that a similar pattern emerges when analysing the different perceptions of morality that the two groups have. We conclude that with increasing disposable income, people with upper social origins become more morally flexible, as they are more tolerant of rule violations and violate the rules more often than individuals with lower social origins.

Humans differ in their strategic reasoning abilities and in beliefs about others' strategic reasoning abilities. Studying such cognitive hierarchies has produced new insights regarding equilibrium analysis in economics. This paper investigates the effect of cognitive hierarchies on long run behavior. Despite short run behavior being highly sensitive to variation in strategic reasoning abilities, this variation is not replicated in the long run. In particular, when generalized risk dominant strategy profiles exist, they emerge in the long run independently of the strategic reasoning abilities of players. These abilities may be arbitrarily low or high, heterogeneous across players, and evolving over time.

Background: Ecological momentary assessment (EMA) has become a popular method of gathering information about participants as they go about their daily lives. However, participant non-compliance, especially non-random compliance, in EMA is a concern. Better knowledge of the moment-to-moment factors that predict prompt non-response can inform the design of strategies to mitigate it. Method: We used data from a general population young adult (n = 260) EMA study, ‘decades-to-minutes’ (D2M) and fitted dynamic structural equation models (DSEMs) to explore a range of candidate momentary predictors of missing the next prompt.Results: We found that higher levels of stress, overall negative affect, and the specific negative affective state of ‘upset’ at a given prompt predicted a greater likelihood of missing the next prompt. However, no other specific affective states, alcohol use, experiencing social provocations nor aggressive behaviour predicted missing the next prompt.Limitations: The primary limitation of the present study was a lack of information on predictors concurrent with missed prompts.Conclusions: Findings point to the potential value of gathering information on momentary negative affect (especially feeling upset) and stress to help inform strategies that intervene to prevent application disengagement at optimal moments and to feed into strategies to mitigate bias due to non-random non-response in EMA studies.

Despite the central role of self-assembled groups in animal and human societies, statistical tools to explain their composition are limited. The authors introduce a statistical framework for cross-sectional observations of groups with exclusive membership to illuminate the social and organizational mechanisms that bring people together. Drawing from stochastic models for networks and partitions, the proposed framework introduces an exponential family of distributions for partitions. The authors derive its main mathematical properties and suggest strategies to specify and estimate such models. A case study on hackathon events applies the developed framework to the study of mechanisms underlying the formation of self-assembled project teams.

Funder: Julius Baer Foundation, Funder: Visana Foundation, Ecological momentary assessment (EMA) methodologies are commonly used to illuminate the predictors and impacts of experiencing subjective stress in the course of daily life. The validity of inferences from this research is contingent on the availability of measures of perceived momentary stress that can provide valid and reliable momentary stress scores. However, studies of the development and validation of such measures have been lacking. In this study, we use an EMA data collection design to examine the within- and between- person reliability and criterion validity and between-person gender measurement invariance of a brief EMA-adapted measure of a widely used trait measure of stress: the Perceived Stress Scale (PSS). Scores showed high internal consistency reliability and significant correlations with a range of criterion validity measures at both the within- and between-person level. Gender measurement invariance up to the scalar level also held for scores. Findings support the use of the EMA-adapted PSS presented in the current study for use in community-ascertained samples to address research questions relating to the influences on and effects of momentary stress and their gender differences.

Abstract: A previous study developed and validated a multi-item instrument for the assessment of violent ideations, the “Violent Ideations Scale” (VIS). However, the final 12-item scale contained no items relating to sexual violence and was thus lacking an important dimension of violence. The current study explores an expansion of the original VIS to include ideations of sexual violence and investigates the psychometric properties of this new version: The Violent Ideations Scale-Extended (VIS-X). The VIS-X was completed by participants in the latest wave of the z-proso study ( N = 1,177; 595 females, 580 males aged 19–22 years). Exploratory factor analysis was conducted in a calibration sample and confirmatory factor analysis in a validation sample to establish a two subscale structure as optimal. Cronbach’s α and Composite Reliability suggested good internal consistency. Nomological analysis supported the convergent validity of the scores.

It is well known that there has been a steady and significant underrepresentation of women in philosophy on different professional levels. Numerous hypotheses explaining this underrepresentation have been suggested, but empirical analyses are not yet extensive. In particular, studies of the phenomenon in different countries are nonexistent. In this paper, we present findings from an exploratory study in which we analyze the interests, abilities, beliefs, attitudes, perceptions, and goals of bachelor’s students in a semester-long philosophy of science course at a major German university. We furthermore make the first attempt to compare women-only learning environments with mixed-gender learning environments. Our results suggest that while there are generally some gender differences regarding interests, abilities, beliefs, attitudes, perceptions, and goals of students in the classroom, most of the hypotheses we explore to explain dropout rates by gender differences cannot be supported. We conclude that possible factors leading to the underrepresentation of women in philosophy in Germany might be found in the social and institutional environment within which philosophy is taught.

Research on key determinants of negative attitudes toward immigration has often suggested that values held by individuals systematically explain such sentiments. Universalists appear to have more positive and conservatives more negative attitudes. So far, however, these insights are based on studies using adult samples. In our study, we analyze these relations among children and adolescents. For the analysis, we utilized a Swiss-Polish panel dataset (2015–2017, N = 5,332) with three time points collected among school children aged 8–19 years. We employed autoregressive cross-lagged models. The results indicated that while universalism decreased negative attitudes toward immigrants, the expected effect for conformity-tradition was not found.

Previous research has identified harsh parenting practices, such as corporal punishment, as a predictor of adolescent behaviour problems such as increased aggression. However, not all children who experience childhood corporal punishment develop increased aggression, making the illumination of factors moderating this link an important question for informing prevention. In the current study, an autoregressive cross-lagged panel model was used to examine teacher-child relationships as both a direct and interactive protective factor (via weakening the effects of corporal punishment exposure) in adolescent aggression. Data was used from the Zurich Project on the Social Development from Childhood to Adulthood (z-proso). Self-reported data was collected at three time points: age 11 (n = 1144, 49% female) age 13 (n = 1366, 49% female) and age 15 (n = 1447, 48% female). Results suggested having a positive teacher-child relationship was a direct protective factor against concurrent aggression. However, there was not consistent evidence for a moderating effect of teacher-child relationships. Implications of these findings are discussed.

In times of cultural omnivorousness, authentic products are highly valued by high-status consumers. The article scrutinizes the social and individual preconditions for attributing hedonic and economic value to authentic products. Taking the concept of cultural capital as a starting point, it argues that cues indicating a product’s authenticity affect taste and price evaluations only if individuals perceive authenticity cues correctly (descriptive beliefs) and regard authenticity as an important product feature (evaluative beliefs). This interplay of descriptive and evaluative beliefs explains the appreciation of authentic products. The model is tested by combining an experimental tasting of apple juice samples with a survey. We find that cues of authenticity causally influence the hedonic evaluation of products only for consumers with both strong descriptive and evaluative beliefs. Attribution of economic value depends on descriptive beliefs only. In addition, such beliefs are socially structured: descriptive beliefs correlate with higher formal education, whereas evaluative beliefs covary with highbrow cultural practices.

This study profile describes COCON – the acronym for COmpetence and CONtext. This is an interdisciplinary, multi-cohort and multi-informant longitudinal study with a primary focus on how children and adolescents cope with the developmental tasks of early life course transitions. It strives to detect the social and individual antecedents and consequences associated with the handling of these transitions. The project frames child and adolescent development in the triple theoretical perspective of challenges imposed by early transitions in the institutionalised life course, inequality in resources and opportunities, and young people’s competencies. Thanks to the longitudinal and multi-cohort design of the study, this conceptual perspective facilitates the joint examination of intra-individual development, inter-individual differences in developmental outcomes and social change in developmental processes. COCON consists of three age groups, whereby each groups represents a prototypical stage in the process of growing up: mid-childhood (6-year-olds), mid-adolescence (15-year-olds) and early adulthood (21-year-olds). The samples are representative for the French- and German-speaking parts of Switzerland. The large sample sizes and the multilingual context of Switzerland permit the analysis of group disparities as well as cross-cultural differences. The multi-informant component of the study includes the primary caregiver and class teacher. The current study profile outlines the most important characteristics of the study in the context of the conceptual framework and discusses strengths and caveats related to study management as well as ethical considerations and information on data availability.

Expectations about the future direct effort in goal-oriented action and may influence a range of life course outcomes, including educational attainment. Here we investigate whether such expectations are implicated in the dynamics underlying the persistence of educational advantage across family generations, and whether such dynamics have changed in recent decades in view of historical change. Focusing on the role of domain-specific (educational) and general (optimism and control) expectations, we examine parallels across parent-child cohorts in (a) the relationships between parental socioeconomic status (SES) and children's future expectations and (b) the associations between children's future expectations and their academic achievement. We estimate structural equation models using data from the prospective multigenerational Youth Development Study (N = 422 three-generation triads [G1-G2-G3]; G1 Mage in 1988 = 41.0 years, G2 Mage in 1989 = 14.7 years, G3 Mage in 2011 = 15.8 years; G2 White in 1989 = 66.4%, G3 White in 2011 = 64.4%; G1 mean annual household income, converted to 2008 equivalents = $41,687, G2 mean annual household income in 2008 dollars = $42,962; G1 mode of educational attainment = high school, G2 mode of educational attainment = some college). We find intergenerational similarity in the relationships between parental educational attainment and children's future expectations. Children's educational expectations strongly predicted their academic achievement in the second generation, but not in the third generation. With educational expansion, the more recent cohort had higher educational expectations that were less strongly related to achievement. Overall, the findings reveal dynamics underlying the persistence of educational success across generations. The role of future expectations in this intergenerational process varies across historical time, confirming a central conclusion of life span developmental psychology and life course sociological research that individual functioning is influenced by sociocultural contexts.

Many common chronic diseases of aging are negatively associated with socioeconomic status (SES). This study examines whether inequalities can already be observed in the molecular underpinnings of such diseases in the 30s, before many of them become prevalent. Data come from the National Longitudinal Study of Adolescent to Adult Health (Add Health), a large, nationally representative sample of US subjects who were followed for over two decades beginning in adolescence. We now have transcriptomic data (mRNA-seq) from a random subset of 4,543 of these young adults. SES in the household-of-origin and in young adulthood were examined as covariates ofa priori-defined mRNA-based disease signatures and of specific gene transcripts identifiedde novo. An SES composite from young adulthood predicted many disease signatures, as did income and subjective status. Analyses highlighted SES-based inequalities in immune, inflammatory, ribosomal, and metabolic pathways, several of which play central roles in senescence. Many genes are also involved in transcription, translation, and diverse signaling mechanisms. Average causal-mediated effect models suggest that body mass index plays a key role in accounting for these relationships. Overall, the results reveal inequalities in molecular risk factors for chronic diseases often decades before diagnoses and suggest future directions for social signal transduction models that trace how social circumstances regulate the human genome.

We test whether the decisions in a common-pool resource game are better modeled game-theoretically as strategic substitutes or complements using an individual-level dataset of groundwater usage that accounts for 3% of US irrigated agriculture. Based on a regression framework with instrumental variables, we find support for strategic complements, suggesting that reciprocity– and/or race-to-depletion–like dynamics are key to understanding groundwater usage., Games, 13 (5), ISSN:2073-4336

Funder: Jacobs Foundation; doi: http://dx.doi.org/10.13039/501100003986, Funder: Schweizerischer Nationalfonds zur Förderung der Wissenschaftlichen Forschung (CH), Developmental trajectories of common mental health issues such as ADHD symptoms, internalising problems, and externalising problems can often be usefully summarised in terms of a small number of 'developmental subtypes' (e.g., 'childhood onset', 'adolescent onset') that may differ in their profiles or levels of clinically meaningful variables such as etiological risk factors. However, given the strong tendency for symptoms in these domains to co-occur, it is important to consider not only developmental subtypes in each domain individually, but also the joint developmental subtypes defined by symptoms trajectories in all three domains together (e.g., 'late onset multimorbid', 'pure internalising', 'early onset multimorbid'). Previous research has illuminated the joint developmental subtypes of ADHD symptoms, internalising problems, and externalising problems that emerge from normative longitudinal data using methods such as group-based trajectory modelling, as well as predictors of membership in these developmental subtypes. However, information on the long-term outcomes of developmental subtype membership is critical to illuminate the likely nature and intensity of support needs required for individuals whose trajectories fit different developmental subtypes. We, therefore, evaluated the relations between developmental subtypes previously derived using group-based trajectory modelling in the z-proso study (n = 1620 with trajectory data at ages 7, 8, 9, 10, 11, 12, 13, 15) and early adulthood outcomes. Individuals with multimorbid trajectories but not 'pure' internalising problem elevations showed higher levels of social exclusion and delinquency at age 20. These associations held irrespective of the specific developmental course of symptoms (e.g., early versus late onset versus remitting). There was also some evidence that intimate partner violence acts as a form of heterotypic continuity for earlier externalising problems. Results underline the need for early intervention to address the pathways that lead to social exclusion and delinquency among young people with multiple co-occurring mental health issues.

Prior research has found evidence for a positive effect of student-teacher bonds on children’s behavior. However, little research has investigated these relations following a transactional model of child development. This study investigated the bidirectional associations between student-teacher relationships and oppositional behaviors towards teachers using the ‘Zurich Project on the Social Development from Childhood to Adulthood’ (n = 1527; median ages 11, 13 and 15; 49% female). Results of a random-intercept cross-lagged panel model suggested that, among boys, positive student-teacher bonds at age 13 were associated with fewer teacher-reported oppositional behaviors two years later. The results indicated that negative interactions with teachers may be part of vicious cycles of poor relationships and increased levels of oppositional behavior, particularly for boys in late adolescence.

Social networking sites have become a predominant means of communication across the globe. Activities on these sites generate massive amounts of personal information and raise concerns about its potential abuse. Means designed to protect the user’s privacy and prevent exploitation of confidential data often go unused. In this study, we draw on the theory of planned behavior, a reasoned action approach, to explain intentions to adopt privacy behaviors on social networking sites, with a focus on Twitter users. Consistent with the theory, an online survey of Twitter users ( n = 1,060) found that instrumental and experiential attitudes and descriptive and injunctive subjective norms regarding these behaviors were direct predictors of intentions. Perceived behavioral control had a moderating effect, such that subjective norm was a better predictor of intentions for participants high as opposed to low in perceived control. We briefly discuss the implications of these results for developing theory-driven and evidence-based interventions to promote privacy behavior.

Accumulating evidence indicates that students' sense of school belonging has a substantial positive effect on educational attainment. At the same time, life course and life span developmental theories suggest that the benefits of a sense of school belonging could be weakened by the channeling effects of education systems that assign students to distinct educational tracks that lead otherwise similar students to quite different educational destinations. The current study analyzed the extent to which the sense of school belonging predicted educational trajectories in a system that partially channels students into distinct tracks. It assessed educational trajectories as they relate to transitions at two critical junctures of the system-the transition from lower- to upper-secondary education, and from upper-secondary to tertiary (university) education. The study used data from a nationally representative panel survey that followed participants from age 15 to 30 (

The companions in crime hypothesis suggests that co-offending moderates the link between peer delinquency and adolescent delinquency. However, this hypothesis has rarely been investigated longitudinally. Hence, this study investigated the co-development of friends’ delinquency and adolescents’ delinquency, as well as the co-development of friends’ delinquency and short-term mindsets (impulsivity and lack of school future orientation). Whether this co-development is stronger when adolescents engage in co-offending was also investigated. Three data waves with two year lags from an ethnically-diverse adolescent sample (at wave 1: N = 1365; 48.6% female; Mage = 13.67; age range = 12.33–15.09 years) in Switzerland were used. The results from parallel process latent growth modeling showed that the co-development between friends’ delinquency and adolescents’ delinquency was stronger when adolescents engaged in co-offending. Thus co-offending likely provides direct access to a setting in which adolescents continue to model the delinquency they learned with their peers.

Latent Profile Analysis (LPA) is a method to extract homogeneous clusters characterized by a common response profile. Previous works employing LPA to human value segmentation tend to select a small number of moderately homogeneous clusters based on model selection criteria such as Akaike information criterion, Bayesian information criterion and Entropy. The question is whether a small number of clusters is all that can be gleaned from the data. While some studies have carefully compared different statistical model selection criteria, there is currently no established criteria to assess if an increased number of clusters generates meaningful theoretical insights. This article examines the content and meaningfulness of the clusters extracted using two algorithms: Variational Bayesian LPA and Maximum Likelihood LPA. For both methods, our results point towards eight as the optimal number of clusters for characterizing distinctive Schwartz value typologies that generate meaningful insights and predict several external variables.

During the recent pandemic, fear of COVID-19 has been widespread and is considered to deteriorate mental health. We assessed whether vaccination can effectively reduce the fear of COVID-19 and, thus, contribute to improving people's mental health status. We used two-wave panel data from a German online study collected in April 2021 (t1) and August/September 2021 (t2) and estimated differences-in-differences to determine whether those who were vaccinated against COVID-19 experienced a reduction of fear of COVID-19, and whether the reduction was more evident as compared to people who were not vaccinated for various reasons. Fear of COVID-19 generally decreased between t1 and t2 for all respondents. Moreover, reduction of fear for people who were unvaccinated at t1 but received the vaccine between t1 and t2 was strongest as compared to people who did not get vaccinated during that period, even after we controlled for factors associated with fear (e.g., age, gender). Vaccination reduced fear of COVID-19 beyond some seasonal fluctuation and, therefore, we argue that vaccination partially reduces the psychological distress caused by the pandemic. We recommend that scientists, practitioners, and politicians highlight this additional positive effect of vaccination in health communication.

Peer reviewed: True, In this paper we examined the impact of the quality of teacher-student relationships at age 10 on young people's delinquency at ages 13, 15, and 17 utilizing propensity-score matching. The young people were matched based on 105 characteristics, measured at ages 7 to 10. The sample comprised 1483 (49.4% female) adolescents representing around 80 different countries of origin, residing in Zurich, Switzerland. We found that young people who reported a better relationship with their teacher at age 10, engaged in fewer delinquent acts at ages 13, 15, and 17. These findings suggest that when young people perceive a better relationship with their teachers this serves as a protective factor against their engagement in delinquency up to 7 years later.

Violent ideations are increasingly recognized as an important psychological predictor for aggressive and violent behavior. However, little is known about the processes that contribute to violent ideations. This paper examines the extent to which polyvictimization triggers violent ideations in late adolescence and early adulthood, while also adjusting for dispositional and situational factors as well as prior violent ideations. Data came from three waves of the Zurich Project on the Social Development from Childhood into Adulthood (z-proso; n = 1465). Full-information maximum likelihood Tobit models were fitted to regress violent ideations experienced at ages 17 and 20 on multiple victimization experiences in the preceding 12 months while controlling for antecedent developmental risk factors and prior violent ideations. The results showed that violent ideations in late adolescence and early adulthood are influenced by violent thoughts, aggressive behavior, violent media consumption, moral neutralization of violence, and internalizing symptoms measured 2 years earlier. Experiences of polyvictimization significantly contributed to an increase in violent ideations both during late adolescence and in early adulthood. The exposure–response relationship between victimization and violent ideations did not significantly differ by sex. The findings are consistent with the notion that violent ideations are triggered by a retaliation-linked psychological mechanism that entails playing out other directed imaginary aggressive scenarios specifically in response to experiencing intentional harm-doing by others.

Many studies have investigated barriers for women and minorities on their way to the top, but very few studies have examined which organizational practices indeed increase the diversity of the top management in organizations. This research analyzes whether various diversity practices increase the proportion of women and minorities at the top. The results show that the more diversity management and family-friendly practices that are implemented, the higher is the proportion of women in management positions. However, the results do not show any effect for diversity training or that people with a migration background benefit from diversity practices.

Social distancing is an effective strategy to mitigate the impact of infectious diseases. If sick or healthy, or both, predominantly socially distance, the epidemic curve flattens. Contact reductions may occur for different reasons during a pandemic including health-related mobility loss (severity of symptoms), duty of care for a member of a high-risk group, and forced quarantine. Other decisions to reduce contacts are of a more voluntary nature. In particular, sick people reduce contacts consciously to avoid infecting others, and healthy individuals reduce contacts in order to stay healthy. We use game theory to formalize the interaction of voluntary social distancing in a partially infected population. This improves the behavioral micro-foundations of epidemiological models, and predicts differential social distancing rates dependent on health status. The model’s key predictions in terms of comparative statics are derived, which concern changes and interactions between social distancing behaviors of sick and healthy. We fit the relevant parameters for endogenous social distancing to an epidemiological model with evidence from influenza waves to provide a benchmark for an epidemic curve with endogenous social distancing. Our results suggest that spreading similar in peak and case numbers to what partial immobilization of the population produces, yet quicker to pass, could occur endogenously. Going forward, eventual social distancing orders and lockdown policies should be benchmarked against more realistic epidemic models that take endogenous social distancing into account, rather than be driven by static, and therefore unrealistic, estimates for social mixing that intrinsically overestimate spreading., Scientific Reports, 11 (1), ISSN:2045-2322

It affords researchers the possibility of collecting data in ecological context, in near real time. However, there is a lack of measures of aggression that have been developed and validated for use in EMA contexts. In this study, we report on the validation of a measure specifically designed to address this need: the Aggression-ES-A. Building on a previous pilot study, we evaluate the within- and between-person reliability, nomological net and associations with a validated trait measure of aggression of the Aggression-ES-A in a sample of N = 255 emerging adults from the Zurich Project on Social Development from Childhood to Adulthood (z-proso). Using multilevel confirmatory factor analysis and structural equation modeling, we found support for the factorial validity, reliability, and concurrent validity of the Aggression-ES-A scores. Results support the use of the Aggression-ES-A in EMA studies utilizing community-ascertained samples.

The current study investigates whether between-person differences in ADHD traits are associated with differences in the within-person moment-to-moment coupling of stress and negative affect; and whether these can explain between-person differences in internalising problems (N = 262, median-age 20). Results of a dynamic structural equation model indicated that between-person differences in ADHD traits significantly moderated the daily life coupling between stress and negative affect. Further, higher ADHD traits were associated with stronger stress carry-over and higher mean levels of negative affect. Stress carry-over and mean levels of negative affect mediated the association between ADHD traits and internalising problems.

Skin cancers related to sunexposure are rising globally, yet largely preventable. Digital solutions enable individually tailored prevention and may play a crucial role in reducing disease burden. We developed SUNsitive, a theory-guided web app to facilitate sun protection and skin cancer prevention. The app collected relevant information through a questionnaire and provided tailored feedback on personal risk, adequate sun protection, skin cancer prevention, and overall skin health. SUNsitive’s effect on sun protection intentions and a set of secondary outcomes was evaluated with a two-arm randomized controlled trial (n = 244). At 2 weeks post-intervention, we did not find any statistical evidence for the intervention’s effect on the primary outcome or any of the secondary outcomes. However, both groups reported improved intentions to sun protect compared to their baseline values. Furthermore, our process outcomes suggest that approaching sun protection and skin cancer prevention with a digital tailored “questionnaire–feedback” format is feasible, well-perceived, and well accepted.

Cross-informant discrepancies (CIDs) in youth behaviour are common. Given that that these same behaviours often show or are perceived to show gender differences, it is important to understand how informant perceptions and their discrepancies are affected by gender. In n=1048 (51% male) grade 5 (age 11) Swiss youth, self- versus teacher- (n=261) CIDs were explored using latent difference score modelling. CIDs in prosociality (β = -.15) and aggression (β=.14) were predicted by child gender after adjusting for a range of covariates. Males reported more aggression than was attributed to them by teachers whereas females reported less aggression than was attributed to them. Both genders reported more prosociality than was attributed to them, with a larger discrepancy for males. Accounting for gender-related informant differences could help improve assessments used to ascertain whether clinically significant problems are present.

BackgroundThe coronavirus disease 2019 (COVID-19) pandemic and associated lockdown could be considered a ‘perfect storm’ for increases in emotional distress. Such increases can only be identified by studies that use data collected before and during the pandemic. Longitudinal data are also needed to examine (1) the roles of previous distress and stressors in emotional distress during the pandemic and (2) how COVID-19-related stressors and coping strategies are associated with emotional distress when pre-pandemic distress is accounted for.MethodsData came from a cohort study (N = 768). Emotional distress (perceived stress, internalizing symptoms, and anger), COVID-19-related stressors, and coping strategies were measured during the pandemic/lockdown when participants were aged 22. Previous distress and stressors were measured before COVID-19 (at age 20).ResultsOn average, participants showed increased levels of perceived stress and anger (but not internalizing symptoms) during the pandemic compared to before. Pre-COVID-19 emotional distress was the strongest predictor of during-pandemic emotional distress, followed by during-pandemic economic and psychosocial stressors (e.g. lifestyle and economic disruptions) and hopelessness, and pre-pandemic social stressors (e.g. bullying victimization and stressful life events). Most health risks to self or loved ones due to COVID-19 were not uniquely associated with emotional distress in final models. Coping strategies associated with reduced distress included keeping a daily routine, physical activity, and positive reappraisal/reframing.ConclusionsIn our community sample, pre-pandemic distress, secondary consequences of the pandemic (e.g. lifestyle and economic disruptions), and pre-pandemic social stressors were more consistently associated with young adults' emotional distress than COVID-19-related health risk exposures.

In this paper, we examine the impact of top managers' social class on their attitude towards employee downsizing. Mobilizing Bourdieu's concepts of social class as a unique social position defined by the combination of economic, cultural, and social capital, we develop hypotheses about the effects of different capital endowments, which we test with unique data on more than 2500 top managers in Germany. We find that both higher economic and higher social capital increase openness towards employee dismissals, while higher cultural capital reduces it. We also find that the overall effect of a top manager's social position is an aggregate of the effects of the individual types of capital: Managers with high cultural, low social and low economic capital are least open to employee dismissals, while those with low cultural, high social and high economic capital are most open – with the other combinations lying somewhere between the two extremes.
