The purpose of this study is to extend the recent operationalization of reactance to a non-Western culture, namely, South Korea. The study uses structural equation modeling, and the findings reveal a significant positive association between controlling language and perceived threat to freedom. Consistent with extant research, a significant positive association emerged between a perceived freedom threat and reactance for South Korean adolescents. Findings from this study support treating reactance as a latent variable comprised of unfavorable cognitions and anger. In addition, in line with psychological reactance theory predictions, reactance arousal is significantly associated with a host of boomerang effects. Results are discussed with an emphasis on the role of psychology reactance theory among adolescents within a collectivist culture.
