Self-concept consistency and short-term stability were investigated in the United States, Australia, Mexico, Venezuela, Philippines, Malaysia, China, and Japan. Evidence for substantial cross-role consistency and reliable within-individual variability in trait self-perceptions were found in each culture. Participants in all cultures exhibited short-term stability in their selfreported traits within roles and moderately stable if-then patterns of trait self-perceptions.Cultural differences, which primarily involved Japan, were partially accounted for by cultural differences in dialecticism, but not self-construals or cultural tightness. In all cultures, satisfaction of needs in various roles partially accounted for within-individual variability in selfreported traits. The results provide support for integrating trait and cultural psychology perspectives, as well as structure and process approaches, in the study of self-concepts across cultures.Keywords: culture; self-concept; consistency; within-individual variability; self-construals; dialecticism; tightness-looseness SELF-CONCEPT CONSISTENCY IN EIGHT CULTURES 3
IntroductionWestern theorists have long contended that a consistent self-concept is important for adjustment and a clear sense of identity (Jahoda, 1958;Jourard, 1965;Maslow, 1954). For example, in Erikson's (1950) theory, healthy mastery of the identity versus role diffusion stage of development involves self-perceptions of inner sameness and continuity. Similarly, Jourard (1965) argued that a psychologically healthy individual retains a consistent self-view across social roles. Consistent with these theories, studies in American samples have linked self-concept inconsistency to a variety of unhealthy outcomes, including anxiety, depression, lower selfesteem, and lower life satisfaction (Campbell, Assanand, & Di Paula, 2003;Donahue, Robins, Roberts, & John, 1993;Sheldon, Ryan, Rawsthorne, & Ilardi, 1997). Researchers who have investigated self-concept consistency across cultures have generally done so by quantifying the amount of variability in participants' ratings of their personality traits across various roles or relationships. In the present study, we extended this research by investigating the cross-role consistency and short-term stability of trait self-SELF-CONCEPT CONSISTENCY IN EIGHT CULTURES 4 perceptions in eight diverse cultures. In formulating hypotheses about cultural differences in consistency it is useful to consider both trait and cultural psychology perspectives.
Trait and cultural psychology perspectives on consistencyFrom trait psychology, we anticipate that people in all cultures exhibit a degree of consistency in how they describe their traits in various roles (Church, 2000;Funder & Colvin, 1991;Oishi, Diener, Scollon, & Biswas-Diener, 2004). In this view, heritable traits contribute to a degree of behavioral consistency in all cultures, which, in turn, leads to some consistency in self-perceptions of one's traits in various roles (Funder, 1995;Wood & Roberts, 2006).
