A predominant dimensional model of general personality structure is the five-factor model (FFM). Quite a number of alternative instruments have been developed to assess the domains of the FFM. The current study compares the validity of 2 alternative versions of the Shedler and Westen Assessment Procedure (SWAP-200) FFM scales, 1 that was developed on the basis of items identified by J. Shedler and D. Westen (2004) and 1 that used items identified by R. R. McCrae, C. E. Lokenhoff, and P. T. Costa (2005). The comparative validity of both measures was examined in a sample of persons who evidenced personality-related problems in living (N = 94). The McCrae et al. Neuroticism, Agreeableness, and Openness scales were superior to their respective Shedler and Westen scales. Both research teams developed comparably valid Extraversion and Conscientiousness scales. Implications of the results for future SWAP-200 research are discussed.
