Previous studies suggested that public trust in government is vital for implementations of social policies that rely on public's behavioural responses. This study examined associations of trust in government regarding COVID-19 control with recommended health behaviours and prosocial behaviours. Data from an international survey with representative samples (N=23,733) of 23 countries were analysed. Specification curve analysis showed that higher trust in government was significantly associated with higher adoption of health and prosocial behaviours in all reasonable specifications of multilevel linear models (median standardised β=0.173 and 0.244, P<0.001). We further used structural equation modelling to explore potential determinants of trust in government regarding pandemic control. Governments perceived as well organised, disseminating clear messages and knowledge on COVID-19, and perceived fairness were positively associated with trust in government (standardised β=0.358, 0.230, 0.055, and 0.250, P<0.01). These results highlighted the importance of trust in government in the control of COVID-19.

The issue of considerable dropout rate in doctoral programs is well documented across a large number of countries. However, few studies address the factors associated with doctoral completion among Non-U.S. countries, multiple universities and fields of research. Nor do they investigate the interactions between these factors. The present paper aimed to overcome these limitations and analyzed the population of doctoral students in all disciplines of the two largest universities of the French-speaking Community of Belgium (N = 1509). Specifically, we focused on several factors: gender, nationality, marital status, master grade, whether students continued at the same university when transitioning to the doctoral degree, whether they continued in the same field, age at registration, research field and funding (i.e., type of funding and associated job requirements). Findings indicate that four factors (marital status, master grade, research field and funding) are directly associated with dropout rate when all factors are considered jointly in the same model. Furthermore, results indicate that some of these factors, such as the marital status and gender, interact. In addition, we found that an accumulation of risk factors leads to a massive increase in dropout rates. Finally, a time course analysis revealed that the highest dropout rate occurs during the first two years and is related to the absence of funding or scholarship. The results, limits and futures perspectives are discussed.

The COVID-19 pandemic presents a global crisis and authorities have encouraged the population to promote preventive health behaviors to slow the spread of the virus. While the literature on psychological factors influencing health behaviors during the COVID-19 is flourishing, there is a lack of cross-national research focusing on multiple health behaviors. The present study overcomes this limitation and affords a validation of the Theory of Planned Behavior (TPB) as a conceptual framework for explaining the adoption of handwashing and limitation of social contacts, two health behaviors that highly differ in their nature. Specifically, we compare TPB model on these two protective behaviors among people living in Belgium (N = 3744) and France (N = 1060) during the COVID-19 sanitary crisis. Data were collected from March 18 until April 19, 2020, which corresponds to the spring lockdown and the first peak of the pandemic in these countries. Results indicated that more positive attitudes, greater social norms, increased perceived control and higher intentions were related to higher adherence to handwashing and limitation of social contacts, for both Belgian and French residents. Ultimately, we argued that the TPB model tends to manifest similarly across countries in explaining health behaviors, when comparing handwashing and limitation of social contacts among individuals living in different national contexts.
