Self-Concept Clarity Scale (SCSS): Psychometric properties and aggression correlates of a German version

Two studies (participants: N =126; N = 247) examined the reliability and validity of the German version of the Self-Concept Clarity Scale (Stucke, 2002). The results from exploratory and confirmatory factor analysis showed a one-factor solution fit best for adults, whereas a two-factor solution fit best for adolescents. Internal reliability was high for adult and adolescent samples. In adults, self-concept clarity was negatively correlated with both narcissism and self-reported aggression. The German version of the SCCS is a useful scale for predicting aggression, especially in adults.
