The Development of Materialism in Emerging Adulthood: Stability, Change, and Antecedents.

The present study investigated stability and change in materialism in emerging adulthood as well as the predictive roles of socioeconomic status (SES) and gender on the development of materialistic values. Indicator-specific latent state-trait growth models were applied to four-wave longitudinal data from a sample of 738 Chinese college students. The results showed that materialism was stable: 67% to 86% of the variance in the reliable interindividual differences in materialism was due to trait factors. In addition, materialism showed an increasing trajectory over the college years, and this developmental trend could not be attributed to measurement artifacts or confounding influences. Moreover, low family SES magnified the increase in materialism, whereas being female predicted lower initial levels of materialism. Collectively, these findings illustrate the nature and antecedents of the development of materialism in emerging adulthood.
