Self-concept clarity in social anxiety: psychometric properties and factor structure of the Self-Concept Clarity Scale in a social anxiety disorder sample

Abstract

ABSTRACT Background The Self-Concept Clarity Scale (SCCS) is a 12-item self-report measure that assesses self-concept clarity (SCC). Previous research has identified a relationship between lower SCC and higher levels of social anxiety. As a measure of positive psychological well-being, the SCCS can be used as a tool to examine and monitor SCC in populations with social anxiety disorder (SAD) who appear to be susceptible to inconsistent or unstable self-concept. However, the scale has yet to be validated with a SAD sample. Methods A confirmatory factor analysis (CFA) was conducted on the SCCS data of sample of 87 individuals who met criteria for a diagnosis of SAD (M = 20.15, SD = 3.55; 83% female) and the reliability, convergent validity and norm scores of the SCCS with a SAD were also investigated. Results Results of the CFA supported a unidimensional factor structure. The SCCS was found to have good internal consistency (Cronbach’s α = .80) and SCCS scores were found to correlate with measures of psychological distress and social fears, however, no correlation was found with measures of social anxiety behaviours. Also, overall results found that the SAD sample scored lower on SCC than other clinical samples in previous literature. Conclusions These findings suggest that the SCCS is a psychometrically sound measure with unidimensional factor structure and demonstrated reliability and validity with a SAD sample, although additional research is warranted to replicate and extend the results of the current research.
