The structure and temporal stability of the Child and Adolescent Perfectionism Scale.

In this study, the authors examined the factor structure and temporal stability of the Child and Adolescent Perfectionism Scale (CAPS; G. L. Flett, P. L. Hewitt, D. J. Boucher, L. A. Davidson, & Y. Munro, 1997) in 2 samples of adolescents (15-16 years old). In Sample 1 (n = 624), confirmatory factor analysis did not support a 2-factor structure (self-oriented and socially prescribed perfectionism). As in B. T. McCreary, T. E. Joiner, N. B. Schmidt, & N. S. Ialongo (2004), reanalysis suggested a 3-factor solution (i.e., socially prescribed perfectionism, self-oriented-Striving perfectionism, self-oriented-Critical perfectionism). The authors validated their 3-factor model in an independent replication sample (Sample 2; n = 514) and confirmed that the 3-factor structure was invariant across gender and time (test-retest over 6 months). Taking these analyses together, the authors concluded that their discriminant 3-factor structure is robust. Theoretical and clinical implications are discussed. More research on the predictive validity of the CAPS is suggested.
