In response to the developing critique of traditional sociological measures of social class, the Differential Status Identity Scale (DSIS) was developed. The DSIS is a measure designed to tap the psychological impact on the individual of belonging to a particular social status. Internal consistency reliability and construct, convergent, and criterion validity of the DSIS were examined for a sample of 454 college students. The present data lent much support to DSIS as a new psychological measure of social status. (Contains 3 tables.)
