Self-concept clarity (SCC) references a structural aspect oftbe self-concept: the extent to which selfbeliefs are clearly and confidently defined, internally consistent, and stable. This article reports the SCC Scale and examines (a) its correlations with self-esteem (SE), the Big Five dimensions, and self-focused attention (Study l); (b) its criterion validity (Study 2); and (c) its cultural boundaries (Study 3). Low SCC was independently associated with high Neuroticism, low SE, low Conscientiousness, low Agreeableness, chronic self-analysis, low internal state awareness, and a ruminative form of self-focused attention. The SCC Scale predicted unique variance in 2 external criteria: the stability and consistency of self-descriptions. Consistent with theory on Eastern and Western selfconstruals, Japanese participants exhibited lower levels of SCC and lower correlations between SCC and SE than did Canadian participants. Within the last couple of decades, psychologists' view of the self-concept has undergone a dramatic transformation (Markus & Wurf, 1987). Early researchers treated the self-concept as a unitary, monolithic entity-a stable, generalized view of the self-and typically focused their research efforts on a single aspect of the self-concept, self-esteem. Contemporary researchers, in contrast, rely on a multifaceted, dynamic construal in which the self-concept is defined as a cognitive schema-an organized knowledge structure that contains traits, values, episodic and semantic memories about the self and controls the processing of self-relevant information (e.g.,

A distinction between ruminative and reflective types of private self-attentiveness is introduced and evaluated with respect to L. R. Goldberg's (1982) list of 1,710 English trait adjectives (Study 1), the five-factor model of personality (FFM) and A. Fenigstein, M. F. Scheier, and A. Buss's (1975) Self-Consciousness Scales (Study 2), and previously reported correlates and effects of private selfconsciousness (PrSC; Studies 3 and 4). Results suggest that the PrSC scale confounds two unrelated, motivationally distinct dispositions-rumination and reflection-and that this confounding may account for the "self-absorption paradox" implicit in PrSC research findings: Higher PrSC scores are associated with more accurate and extensive self-knowledge yet higher levels of psychological distress. The potential of the FFM to provide a comprehensive framework for conceptualizing self-attentive dispositions, and to order and integrate research findings within this domain, is discussed.

Recent recognition that the dominance and nurturance dimensions of the interpersonal circumplex correspond closely to the surgency/extraversion and agreeableness dimensions of the five-factor model of personality provides an occasion for the closer integration of these two traditions. We describe the procedures whereby we extended our adjectival measure of the circumplex Revised Interpersonal Adjective Scales (IAS-R) to include the additional Big Five dimensions of conscientiousness, neuroticism, and openness to experience. The resultant five-scale instrument (IASR-B5) was found to have excellent structure on the item level, internally consistent scales, and promising convergent and discriminant properties when compared with the NEO Personality Inventory and the Hogan Personality Inventory. The unique feature of the IASR-B5 is that it provides a highly efficient instrument for combined circumplex and five-factor assessment. We provide an example of such combined assessment.

The importance of the interpersonal circle in organizing the interpersonal domain is complemented by its empirical relations with broader personality taxonomies and with more specific personality variables. Yet circumplex structure in interpersonal measures has often been investigated using the "eyeball test" rather than using circumplex criteria of known effectiveness. Simulations (Acton, 1999) showed the effectiveness of 5 exploratory criteria (3 entirely new) that assess the properties of equal spacing, constant radius, and no preferred rotation. Along with Browne's (1992) criterion, these were applied to the Interpersonal
