Two studies were conducted to explore the nature of private and public self-consciousness, as measured by the two principal subscales of the Self-Consciousness Scale (SCS; Fenigstein, Scheier, & Buss, 1975). The first study assessed the effects of two common manipulations of self-awareness
– the presence of a small mirror and a salient audience – on 60 college students' private and public SCS scores. Neither of these manipulations affected students' scores on the two subscales, supporting the assumption that the private and public SCS subscales measure
relatively stable traits or dispositions. In Study II, the SCS was administered to 120 psychiatric inpatients diagnosed “schizophrenic“ or “affective disordered.“ No significant mean differences on either the private or public SCS subscales were found among the schizophrenic
patients, affective disordered patients, and undergraduates (of Study 1). The clinical samples did differ from the non-clinical sample, however, in the strength of the relation between private and public self-consciousness.
