An instrument (SCOI) was designed to measure Fromm's (1955) marketing character, which is based on the notion that the self may be experienced as a commodity whose value and meaning are externally determined. In study 1 (N=80 & 302), the hypothesis that the SCOI would
be positively correlated with Conformity, Authoritarianism and Anger Expression was supported, providing support for Fromm's (1955) theory that these latter three traits would be evident in those individuals defined by the marketing character. The hypotheses that the SCOI and Materialism
(Richins & Dawson, 1992), would be positively correlated with both Commercial Television Viewing and Anxiety were also supported. In study 2 (N=87), the hypotheses that the SCOI and Materialism would be positively correlated with Depression and negatively correlated with Voluntary
Simplicity were supported. The hypothesis that the SCOI would be negatively correlated with Life Satisfaction was not supported, although Materialism was significantly and negatively correlated with Life Satisfaction. In study 3 (N=80), the hypotheses that the SCOI and Materialism would
be negatively correlated with Empathy and Neuroticism were not supported, the latter result suggesting that neuroticism may not be an adequate indicator of psychological health per se. In study 4 (N=101), the hypotheses that the SCOI and Materialism would be negatively correlated with
Biophilia and Environmentalism were also supported. Further, the SCOI was able to discriminate both between Ss from Newcastle, NSW (one of two preferred test markets in Australia) and Ss from a permaculture community in south-east Queensland, Australia, and between Ss enrolled in management
and Ss enrolled in arts/science at the University of Newcastle, NSW, Australia. Hence, the SCOI generally performed as expected in tests of convergent, divergent and discriminant validity.
