Cultures responded to the COVID-19 pandemic differently. We investigated cultural differences in mental health during the pandemic. We found regional differences in people's reports of anxiety in China over two years from 2020 to 2021 (N = 1186). People in areas with a history of rice farming reported more anxiety than people in wheat-farming areas. Next, we explored more proximal mechanisms that could help link the distal, historical factor of rice farming to people's modern experience of anxiety. Rice areas scored higher on collectivism and tight social norms than wheat areas, and collectivism, rather than norm tightness, mediated the rice-anxiety relationship. These findings advance our understanding of the distal sources of cultural differences, the proximal mechanisms, and mental health problems during the pandemics.  相似文献

This study was undertaken to examine ambiguities in the ability of the I-E scale to predict complex social behavior. An analysis of the items in the I-E scale suggested that the scale might contain a conservative bias Further, it was suggested that responses to the items may be determined by the individual's political and social ideology, which in turn are influenced by the political and social norms to which he has been exposed The sample consisted of one parent and a college-aged child from 60 upper-middle-class families in which the parent was visible in the community for political and social participation, half the parents interviewed were liberal, and half conservative in their political views A number of measures of political and social participation were administered, along with a shortened version of the I-E scale The findings of the study supported the contention that the “internal” items on the I-E scale are more congenial to persons holding conservative political views than for those holding liberal views. Perceived internal causality, as measured by the I-E scale, was found to be nonsignificantly correlated with any of the measures of political participation for the parent sample, with five of the six correlations being in the opposite direction from that predicted by social learning theory The results of the study were discussed in terms of White's distinction between the “moralizer” and “reformer” approach to social problems The validity of the I-E scale as a measure of a stable personality trait was called into question, as was its usefulness in predicting complex social behavior  相似文献
