Abstract
The 12 indices of self-perception in the Tennessee Self Concept Scale, together with the Eysenck Personality Inventory, were factor analysed using data obtained from psychiatric day-care patients (n = 131). Separate item- and scale-level factor analyses revealed that: (1) the five external and three internal domains of self-concept, hypothesized as distinct, may be accurately viewed as lying in one-dimensional space; (2) the conflict, variability and distribution scores are unrelated to subtype of self-esteem; (3) extraversion and neuroticism form a bipolar factor that is orthogonal to self-concept; and (4) the emergence of 30 item-factors with a 30 per cent factorial overlap implies a good deal of spuriously shared variance, low inter-scale homogeneity and sizable redundancy in the TSCS scales. Owing to these results, the construct and factorial validity of the TSCS is seriously questioned. It is suggested that future researchers develop more sensitive, treatment-oriented (or idiographic) measures to compare man's less conspicuous and more private 'self-image feelings and cognitions' against his public self-disclosure in the interests of facilitating more rapid behavioural change.
