A synthesis of evidence for policy from behavioural science during COVID-19.

Scientific evidence regularly guides policy decisions1, with behavioural science increasingly part of this process2. In April 2020, an influential paper3 proposed 19 policy recommendations ('claims') detailing how evidence from behavioural science could contribute to efforts to reduce impacts and end the COVID-19 pandemic. Here we assess 747 pandemic-related research articles that empirically investigated those claims. We report the scale of evidence and whether evidence supports them to indicate applicability for policymaking. Two independent teams, involving 72 reviewers, found evidence for 18 of 19 claims, with both teams finding evidence supporting 16 (89%) of those 18 claims. The strongest evidence supported claims that anticipated culture, polarization and misinformation would be associated with policy effectiveness. Claims suggesting trusted leaders and positive social norms increased adherence to behavioural interventions also had strong empirical support, as did appealing to social consensus or bipartisan agreement. Targeted language in messaging yielded mixed effects and there were no effects for highlighting individual benefits or protecting others. No available evidence existed to assess any distinct differences in effects between using the terms 'physical distancing' and 'social distancing'. Analysis of 463 papers containing data showed generally large samples; 418 involved human participants with a mean of 16,848 (median of 1,699). That statistical power underscored improved suitability of behavioural science research for informing policy decisions. Furthermore, by implementing a standardized approach to evidence selection and synthesis, we amplify broader implications for advancing scientific evidence in policy formulation and prioritization.

Employment Disruption and Wellbeing Among Young Adults: A Cross-National Study of Perceived Impact of the COVID-19 Lockdown.

Young adulthood (18-30 years old) is a crucial period due to its developmental tasks such as career establishment and financial independence. However, young adults' relative lack of resources makes them vulnerable to employment disruptions (job loss and income loss), which may have both immediate and long-term effects on their financial wellbeing and mental health. The economic impact of COVID-19 restrictions resulted in an increase in unemployment and a decrease in income worldwide, especially for young adults. This study examined to what extent and how job loss and income loss due to the pandemic influenced young adults' perception of their present financial wellbeing, future financial wellbeing, and psychological wellbeing by using cross-sectional survey data collected from six countries (China, Italy, Lithuania, Portugal, Slovenia, and the United States). Results showed that the impact of income loss and job loss on all three types of wellbeing were mediated by young adults' negative perception of the COVID-19 lockdown restriction (i.e., perceived as a misfortune). Cross-country differences existed in the key variables. The association between employment disruptions, young adults' perception of the COVID-19 lockdown restriction, and wellbeing were equivalent across countries except China. Implications for policy and practice are discussed.

The role of higher education and civic involvement in converting young adults' social responsibility to prosocial behavior.

This study investigates the indirect mechanisms relevant to converting young adults' prosocial attitudes and individual responsibility into their prosocial behavior. Our results are based on a sample of 530 young adults studying at three public regional business schools in South East Europe. They show a significant favorable influence on young adults' civic and political involvement, mediating the relationship between individual responsibility attitudes and prosocial behavior. However, this would not have been expected based on previous research. Another indirect path between the same variables is modeled using a hypothesized moderated mediation effect. The institutional influence of higher education proves to be a significant mediator of the proposed relationship, moderated by the amount of educational content in the fields of ethics, social and environmental responsibility. At mid-and-high levels of exposure to relevant educational content, this indirect path significantly influences the developing young adults' pro-environmental behaviors. The study results are discussed from the viewpoint of peripheral regions with a history of dysfunctional social capital mechanisms.

Self-blame predicts anxiety and depression in infertile couples who opt for in vitro fertilisation (IVF) treatment.

The study examined the use of maladaptive coping strategies such as conflict, avoidance and self-blame in predicting anxiety and depression in couples undergoing IVF procedure. The target group consisted of 80 couples who started the IVF treatment at the Division of Obstetrics and Gynaecology, Ljubljana's University Medical Centre in Slovenia. The participants completed three scales: S/T Anxiety Inventory, CES Depression Scale, and Marital Coping Inventory. The results showed increased rates of depression compared to the normative population; 18% of women and 14% of men reported mild to moderate depression or the possibility of major depression. Women showed higher anxiety scores than men. Coping strategies predicted both depression and anxiety, with self-blame being the most toxic one. The study showed that self-blame is a coping strategy that should be properly addressed in the couples at the very outset of IVF treatment, to decrease emotional disorders and increase the likability of a succesful IVF medical procedures.

Profiles of emerging adults' resilience facing the negative impact of COVID-19 across six countries.

Although emerging adults (i.e., individuals aged 18-29 years old) may be at a lesser risk of COVID-19 severe illness and mortality, studies have found that the negative impact of COVID-19 on mental health and well-being is higher among emerging adults when compared to other age groups. The current study aimed to identify profile(s) based on resilience resources, which could help emerging adults in managing the disruptions to their lives following the pandemic. A cross-national sample of 1,768 emerging adults from China, Italy, Lithuania, Portugal, Slovenia, and the US was utilized to identify profiles based on different resilience dimensions (ego-resiliency, positivity, religiosity, socioeconomic status, family support, peer support). Results of the Latent Profile Analysis suggest the presence of four different profiles: no resources, only peer, only family, and well-equipped. The association of these profiles with demographic variables, adulthood markers, self-perceived COVID-19 impact, present well-being, and future life perception was investigated. Implications for resilience theory as well as for future interventions are discussed.

Value Orientations and Institutional Trust as Contributors to the Adoption of Online Services in Youth: A Cross-Country Comparison.

Internet usage data from around the globe show that adolescents are the most frequent Internet users, but mostly for leisure activities and maintaining social contacts. In the present study, we focused on Internet use for e-services, which could improve youth efficiency in the financial domain (responsible consumer behaviour) and bridge the online divide in youth. Specifically, we explored how societal constructs (namely, institutional trust and personal values) influence the use of the Internet for online shopping, e-banking and communication with providers of goods and services online. We used a representative sample of adolescents (N = 10.902) from 10 countries of Southeast Europe where a great variability in Internet use is present, and where the use of e-services is generally lower than the EU average. This also allowed for meaningful cross-country comparisons. We tested a structural equation model of values predicting the use of the Internet through institutional trust (including some relevant demographic variables such as settlement size, SES and Internet use frequency) which was grounded in social capital theory, cultural theory and Schwartz human values model. The model exhibited a good fit to the data but the strengths of regressional paths were rather modest. Looking into the cross-country stability of the model, however, revealed some notable differences: while the relationship between trust and use of the Internet for e-services was modest in some countries, the relationship was insignificant in other countries, where Internet usage is lower in general. This suggests that strategies aimed at leveraging e-services and digital technology potential in youth should also account for cultural specificities in the transitional economies and cultural settings with sub-optimal adoption of digital services.

How culturally unique are pandemic effects? Evaluating cultural similarities and differences in effects of age, biological sex, and political beliefs on COVID impacts.

Despite being bio-epidemiological phenomena, the causes and effects of pandemics are culturally influenced in ways that go beyond national boundaries. However, they are often studied in isolated pockets, and this fact makes it difficult to parse the unique influence of specific cultural psychologies. To help fill in this gap, the present study applies existing cultural theories via linear mixed modeling to test the influence of unique cultural factors in a multi-national sample (that moves beyond Western nations) on the effects of age, biological sex, and political beliefs on pandemic outcomes that include adverse financial impacts, adverse resource impacts, adverse psychological impacts, and the health impacts of COVID. Our study spanned 19 nations (participant N = 14,133) and involved translations into 9 languages. Linear mixed models revealed similarities across cultures, with both young persons and women reporting worse outcomes from COVID across the multi-national sample. However, these effects were generally qualified by culture-specific variance, and overall more evidence emerged for effects unique to each culture than effects similar across cultures. Follow-up analyses suggested this cultural variability was consistent with models of pre-existing inequalities and socioecological stressors exacerbating the effects of the pandemic. Collectively, this evidence highlights the importance of developing culturally flexible models for understanding the cross-cultural nature of pandemic psychology beyond typical WEIRD approaches.

Saving of Freshmen and Their Parents in Slovenia: Saving Motives and Links to Parental Financial Socialization.

Spending money within the budget, financial planning, and saving represent important positive financial behaviors that contribute to financial satisfaction of emerging adults, which in turn predicts their satisfaction with life. In a mixed method study of Slovenian first-year university students (N = 515) and one of their parents, we qualitatively and quantitatively analyzed multi-informant survey data collected online on their motivation to save money and the factors that influence the students' choice (demographics, parental saving, and parental financial socialization). More than half of the freshmen and their parents saved money, mostly for long-term financial goals, larger investments, financial security in the future, and with self-gratification motives. Saving and the motives for saving were moderately associated within the student-parent dyads: The students whose parents saved tended to save themselves, and the saving motives of parents and their emerging adult children also showed similarities. The role of parents as agents of financial socialization in the students' healthy financial behavior was supported by significant associations between the students' recollection of parental socialization practices (direct financial teaching and financial monitoring) and their money saving.

One Hundred and Sixty-One Days in the Life of the Homopandemicus in Serbia: The Contribution of Information Credibility and Alertness in Predicting Engagement in Protective Behaviors.

COVID-19 pandemic is a long-lasting process associated with dynamic changes within society and in individual psychological responses. Effective communication of measures by credible sources throughout the epidemic is one of the crucial factors for the containment of the disease, and the official communication about pandemics is straightforwardly directed toward changes in behavior via engagement in (self-)protective measures. Calls for the adherence to these measures are aimed at the general population, but people's reactions to these calls vary depending on, for example, their individual differences in cognitive and emotional responses to the situation. The focus of our study was the general narrative about the epidemic as conveyed by both state officials and media outlets in times of decreased social contacts due to the quarantine, in which relying on these sources of information is even more pivotal. Our aim was to explore the stability of the proposed mediational model during the course of the epidemic in Serbia. In the model, we tested the relationship between perceived credibility of information (PCI) and two types of protective behavior-the actual self-protective behavior (ASPB) and the hypothetical protective behavior (HPB), as well as the potential mediating role of alertness in these relationships time-wise. A cross-sectional study (N = 10,782, female = 79.1%) was being administered daily during the first epidemic wave and in three more 2-week time frames during the second wave. Based on the variability of these measures during the first epidemic wave, three stages of psychological responses were mapped (acute, adaptation, and relaxation stage), which were observed, with some deviations, also in the second wave. The mediational model was relatively robust after the initial few weeks, but the strength of pairwise relationships was more changeable. With both types of protective behaviors, the predictive power of PCI was partially mediated through alertness. This suggests that, while individual differences in cognitive and affective responses are important, so is coherent, focused, and credible communication in all stages of the epidemic, which emphasizes the communality aspect of the social containment of the infection. Our findings can thus be valuable in informing the planning of effective future communication.

The general fault in our fault lines.

Pervading global narratives suggest that political polarization is increasing, yet the accuracy of such group meta-perceptions has been drawn into question. A recent US study suggests that these beliefs are inaccurate and drive polarized beliefs about out-groups. However, it also found that informing people of inaccuracies reduces those negative beliefs. In this work, we explore whether these results generalize to other countries. To achieve this, we replicate two of the original experiments with 10,207 participants across 26 countries. We focus on local group divisions, which we refer to as fault lines. We find broad generalizability for both inaccurate meta-perceptions and reduced negative motive attribution through a simple disclosure intervention. We conclude that inaccurate and negative group meta-perceptions are exhibited in myriad contexts and that informing individuals of their misperceptions can yield positive benefits for intergroup relations. Such generalizability highlights a robust phenomenon with implications for political discourse worldwide.

Emotional Responses and Self-Protective Behavior Within Days of the COVID-19 Outbreak: The Promoting Role of Information Credibility.

Due to changes in the information environment since the last global epidemic, high WHO officials have spoken about the need to fight not only the current COVID-19 pandemic but also the related infodemic. We thus explored how people search for information, how they perceive its credibility, and how all this relates to their engagement in self-protective behaviors in the crucial period right after the onset of COVID-19 epidemic. The online questionnaire was circulated within 48 h after the first case of COVID-19 was confirmed in Slovenia. We gathered information on participants' demographics, perception of the situation, their emotional and behavioral responses to the situation (i.e., self-protective behavior), perceived subjective knowledge, perceived credibility of different sources of information, and their level of trust. We looked into the relationships between perceived credibility and trust, and self-protective behavior of 1,718 participants and found that mass media, social media, and officials received relatively low levels of trust. Conversely, medical professionals and scientists were deemed the most credible. The perceived credibility of received information was linked not only with lower levels of negative emotional responses but also with higher adherence to much needed self-protective measures, which aim to contain the spread of the disease. While results might vary between societies with different levels of trust in relevant governmental and professional institutions, and while variances in self-protective behavior scores explained by our model are modest, even a small increase in self-protective behavior could go a long way in viral epidemics like the one we are facing today.

Parental Decision-Making on Childhood Vaccination.

A growing number of parents delay vaccinations or are deciding not to vaccinate their children altogether. This increases the risk of contracting vaccine-preventable diseases and disrupting herd immunity, and also impairs the trust in the capacities of health care systems to protect people. Vaccine hesitancy is related to a range of both psychological and demographic determinants, such as attitudes toward vaccinations, social norms, and trust in science. Our aim is to understand those determinants in parents, because they are a special group in this issue-they act as proxy decision makers for their children, who are unable to decide for themselves. The fact that deciding to vaccinate is a socially forced choice that concerns a child's health makes vaccine-related decisions highly important and involving for parents. This high involvement might lead to parents overemphasizing the potential side effects that they know to be vaccine-related, and by amplifying those, parents are more focused on the potential outcomes of vaccine-related decisions, which can yield specific pattern of the outcome bias. We propose two related studies to investigate factors which promote vaccine hesitancy, protective factors that determine parental vaccination decisions, and outcome bias in parental vaccination intentions. We will explore demographic and psychological factors, and test parental involvement related to vaccine hesitancy using an online battery in a correlation panel design study. The second study is an experimental study, in which we will investigate the moderating role of parents' high involvement in the specific domain of vaccination decision making. We expect that higher involvement among parents, compared to non-parents, will shape the pattern of the proneness to outcome bias. The studies will be conducted across eight countries in Europe and Asia (Finland, Germany, Hong Kong, the Netherlands, Serbia, Slovenia, Spain, and the United Kingdom), rendering findings that will aid with understanding the underlying mechanisms of vaccine hesitancy and paving the way for developing interventions custom-made for parents.
