Objectives: To examine the mediation role of self-care between stress and psychological well-being in the general population of four countries and to assess the impact of sociodemographic variables on this relationship. Design: Cross-sectional, online survey. Participants: A stratified sample of confined general population (N=1082) from four Ibero-American countries—Chile (n=261), Colombia (n=268), Ecuador (n=282) and Spain (n=271)—balanced by age and gender. Primary outcomes measures: Sociodemographic information (age, gender, country, education and income level), information related to COVID-19 lockdown (number of days in quarantine, number of people with whom the individuals live, absence/presence of adults and minors in charge and attitude towards the search of information related to COVID-19), Perceived Stress Scale-10, Ryff’s Psychological Well-Being Scale-29 and Self-Care Activities Screening Scale-14. Results: Self-care partially mediates the relationship between stress and well-being during COVID-19 confinement in the general population in the total sample ( F (3,1078)=370.01, p<0.001, R 2 =0.507) and in each country. On the other hand, among the evaluated sociodemographic variables, only age affects this relationship. Conclusion: The results have broad implications for public health, highlighting the importance of promoting people’s active role in their own care and health behaviour to improve psychological well-being if stress management and social determinants of health are jointly addressed first. The present study provides the first transnational evidence from the earlier stages of the COVID-19 lockdown, showing that the higher perception of stress, the less self-care activities are adopted, and in turn the lower the beneficial effects on well-being.

The aim of the present cross-sectional study was to analyze the differential impact of the first COVID-19 lockdown (3 April 2020) on stress, health practices, and self-care activities across different Hispanic countries, age range, and gender groups. One thousand and eighty-two participants from Spain, Chile, Colombia, and Ecuador took part in this study. Irrespective of the country, and controlling for income level, young people, especially females, suffered a greater level of stress, perceived the situation as more severe, showed less adherence to health guidelines, and reported lower levels of health consciousness, in comparison to their male peers and older groups. However, in the case of self-care, it seems that older and female groups are generally more involved in self-care activities and adopt more healthy daily routines. These results are mostly similar between Colombia, Ecuador, and Spain. However, Chile showed some different tendencies, as males reported higher levels of healthy daily routines and better adherence to health guidelines compared to females and people over the age of 60. Differences between countries, genders, and age ranges should be considered in order to improve health recommendations and adherence to guidelines. Moreover, developing community action and intersectoral strategies with a gender-based approach could help to reduce health inequalities and increase the success of people’s adherence to health guidelines and self-care-promoting interventions. Future studies should be addressed to explore the possible causations of such differences in more cultural-distant samples and at later stages of the current outbreak.

The aim of the present cross-sectional study was to analyze the differential impact of the first COVID-19 lockdown (3rd April 2020) on stress, health practices, and self-care activities across different Hispanic countries, age range and gender groups. 1082 participants from Spain, Chile, Colombia, and Ecuador took part in this study. Irrespective of the country, and controlling for income level, young people, especially females, suffered a greater level of stress, perceived the situation as more severe, showed less adherence to health guidelines and reported lower levels of health consciousness, in comparison to their male peers and older groups. However, in the case of self-care, it seems that older and female groups are generally more involved in self-care activities and adopt more healthy daily routines. These results are mostly similar between Colombia, Ecuador, and Spain. However, Chile showed some different tendencies, as males reported higher levels of healthy daily routines and better adherence to health guidelines compared to females and people over the age of 60. Differences between countries, genders and age ranges should be considered in order to improve health recommendations and adherence to guidelines. It would also be crucial to identify vulnerable groups to promote the adoption of health behaviors that may help in the development of effective public health strategies. Future studies should be addressed to explore the possible causations of such differences in more cultural-distant samples and at later stages of the current outbreak.

Executive functions (EF) correspond to a general construct of high-order cognitive skills aimed at optimizing problem solving. The study of EF categorizes it into three sub-processes; of these three, cognitive flexibility (CF) stands out because of its later development and because it requires a greater amount of neurocognitive resources. In developing an affective understanding of EFs, recent research has outlined the existence of hot EFs, referring to processing skills used in situations that are motivationally and emotionally charged, contrasting with cold EFs, which refer to skills we use in abstract situations and when the affective component is minimal. The purpose of this research study is to explore how different levels of affective salience can modulate performance and processing through the application of a standard CF task. At the behavioural level, participants presented lower reaction times, and the accuracy of their responses was unaffected, under conditions of low affective salience. At the level of brain activity, they presented latencies related to early attention processing and greater occipital activation under conditions of high affective salience.
