Different countries were successful in different ways in their attempts to contain the spread of the coronavirus, which compromised the health of many people. Stress levels rose and the restrictive measures impacted the citizens' trust in institutions. An important resource for managing crises is a country’s economic growth. Given that the gross domestic product (GDP) per capita is one indicator of economic growth, the goal of this study is to investigate the differences in perceived stress and trust in institutions between European countries categorized into below-average, average and above-average GDP per capita levels during the coronavirus pandemic. The analyses of N = 84,080 participants from 29 countries gathered via an online survey showed that citizens of higher-level GDP per capita countries experienced less stress and had more trust in institutions. Compared to the average level, Croatian citizens experienced somewhat higher stress and had somewhat higher trust in the government’s measures. These results imply that economic growth is one of the country-level factors associated with the quality of managing the coronavirus pandemic.

To tackle the spread of COVID‐19, governments worldwide have implemented restrictive public health behavioural measures. Whether and when these measures lead to positive or negative psychological outcomes is still debated. In this study, drawing on a large sample of individuals (N total = 89,798) from 45 nations, we investigated whether the stringency of public health measures implemented at the outset of the COVID‐19 pandemic in March–May 2020 was associated with individuals’ levels of stress and compliance. Moreover, we addressed the question of how these associations may be moderated by the measures’ implementation lag, nations’ tolerance for unequal distributions of power (i.e., power distance), and individuals’ institutional trust. Linear mixed models suggested that slower implementation of less stringent measures was associated with higher stress and lower compliance. Also, rapid implementation of stricter measures was associated with a mild increase in stress. Such effects were especially pronounced in countries with less tolerance for inequality. Albeit significant, the moderating effect of institutional trust was very small. The results suggest that it may be important to consider the measures’ implementation lag when tackling the spread of COVID‐19, but findings should be interpreted in relation to the data collection period.

The main aim of this study was to determine the extent to which the loneliness in adolescencecan be explained by self-esteem and peer pressure. In fact, numerous studies have mostly focusedon bivariate relation between these variables and so far in the Croatian sample of adolescentsis not examined relations between loneliness, self-esteem and peer pressure simultaneously.Although most authors believe that loneliness can occur in all developmental periods, it has beenemphasized that loneliness is more expressed during adolescence and even the most during theperiod of early adolescence. Establishing and maintaining satisfactory relationships is a priority,as inadequate and unsupported relationships with peers makes a risk for the experience ofloneliness. In addition to peer relationships, a positive attitude about yourself, or self-esteem hasa significant role in the successful development of adolescents. Earlier studies have shown thatself-esteem, which decreases during early adolescence, is an important determinant of loneliness.Therefore, the sample of this study consisted of two groups of adolescents, 200 seventh graders,who represented a group of early adolescents, and 200 students of fourth graders of highschool, who formed a group of late adolescents. The questionnaire, which consisted of threegroups of scale, Short version UCLA scale, Self-liking/self-competence Scale-Revised Versionand Susceptibility to Peer Pressure Scale. The results showed a higher level of loneliness inearly adolescents, and lower self-esteem, but a greater level of susceptibility to peer pressurein relation to the late teens. Girls, regardless of age had slightly lower self-esteem compared toboys, while the level of loneliness does not change significantly with respect to sex. However,male adolescents are more prone to risk behavior (eg, consumption of opiates and risky sexualbehavior) and inappropriate behavior at school (eg. unexcused absence from class) under theinfluence of peers. Finally, negative self-image, or low self-esteem and expressed susceptibility topeer pressure are significant determinants of loneliness in adolescence. The results are explainedin terms of developmental changes that make adolescents at risk for the occurrence of loneliness.
