BackgroundA novel coronavirus (SARA-CoV-2) emerged in Wuhan, China, in December 2019. Within a few weeks, the disease caused by SARA-CoV-2, which is named COVID-19, has escalated into an unprecedented ongoing outbreak with frightening speed, becoming a global health emergency. This study aimed to exam the prevalence and risk factors of acute posttraumatic stress symptoms (PTSS) in Chinese people shortly after the massive outbreak of COVID-19.

Although previous investigations have agreed that Chinese rural-to-urban migrants’ socioeconomic status (SES) increases with their migration, the association between SES and subjective well-being is uncertain. To address this research gap, the present study proposed that the association between objective SES and subjective well-being is mediated by subjective SES. This model was tested with a sample of 432 Chinese rural-to-urban migrants. The results indicate a significant association between objective SES and subjective well-being and a partial mediating effect of subjective SES. Furthermore, subjective social mobility, which is one’s expectation about the possibility to move upward in the social hierarchy, was found to moderate both the direct path from objective SES to subjective well-being and the indirect path from subjective SES to subjective well-being. These findings suggest that Chinese rural-to-urban migrants gained in subjective well-being not only because of direct financial achievement but also because of their perceptions and beliefs about their relative social status.

The prevalence of behavioral inhibition in toddlers was examined in five cultures. Participants in this study included 110 Australian, 108 Canadian, 151 Chinese, 104 Italian, and 113 South Korean toddlers and their mothers who were observed during a structured observational laboratory session. Matched procedures were used in each country, with children encountering an unfamiliar stranger with a truck and a robot. Indicators of inhibition included the length of time toddlers delayed before approaching the stranger and the duration of contact with their mother while the stranger was in the room. Results were generally consistent with expectations and showed differences between eastern and western cultures; Italian and Australian toddlers were less inhibited than toddlers from the other countries, whereas Chinese and South Korean toddlers were more inhibited. The implications of these findings are discussed and a research agenda for further exploration of inhibition is outlined.
