“…For instance, Cai and colleagues (2012) examined whether socioecological factors that have become prevalent in recent decades in China-affluence, urbanization, and single-child households-are predictive of one psychological process sometimes associated with individualism, namely, narcissism (Twenge et al, 2008). This research revealed that all three socioecological factors examined were independently predictive of narcissism-a higher score of narcissism was found among affluent (vs. less affluent) participants, those living in urban (vs. rural) areas, and those without (vs. with) siblings (see also Hamamura et al, 2013). However, these inferences have limitations- Yang (1996) interpreted such a tendency from a qualitative review of Chinese personality research, and Cai and colleagues inferred such a pattern from cross-sectional data obtained among contemporary Chinese participants.…”
