Original 12-item SCCS

Ready-to-cite methods sentence

Self-concept clarity was measured with the 12-item SCCS (Campbell et al., 1996), a unidimensional measure with good original-sample internal consistency (α = .86).

Reliability & validation

Validation population
Canadian undergraduate validation samples (Campbell et al., 1996)
Test–retest
0.79

Known limitations

The scale treats clarity, consistency, and temporal stability as one construct, and cultural differences can affect its associations with well-being. Lower scores are not evidence of pathology. Confirm reproduction terms before administration.
