The meaning and measurement of self-complexity

The self-complexity (SC) theory is a structural model of self-knowledge that suggests individual differences in the complexity of knowledge about the self are predictive of emotional stability and reactivity to stress. Various studies have identified problems concerning the consistency, reliability and validity of the often used measure of SC, the dimensionality statistic (H; ). Addressing these issues, the present study proposes 2 alternative measures of the components of SC and examines psychometric properties of these measures. Results of this study indicate a lack of a general factor underlying the dimensionality statistic. In addition, they offer support for the benefit of distinguishing between 2 components of self-complexity: quantity of self-aspects and overlap among them.
