Measurement invariance of the Straightforwardly-Worded Social Interaction Anxiety Scale and Associations with life satisfaction among emerging adults attending University in 10 countries

= 19.89 years, SD = 1.83; 65 % females) from 10 countries (i.e., Argentina, Australia, Canada, China, India, Italy, South Korea, Norway, Turkey, and the United States), who completed self-report assessments of social anxiety and life satisfaction. Findings from a multiple-group factor analysis alignment method indicated approximate measurement invariance for the S-SIAS across the 10 country sites. University students from Norway reported the highest mean level of social anxiety of all groups, whereas participants from Argentina reported the lowest social anxiety. Results from multigroup regression analysis indicated that social anxiety was negatively associated with life satisfaction in all samples (except for Argentina and Australia, where the life satisfaction measure was not collected), but the strength of the association was stronger in Norway compared to samples from other countries. Results are discussed in terms of the meaning and implication of social anxiety across cultures.
