Weighing evidence for the Rorschach's validity: a response to Wood et al. (1999).

Résumé

Wood, Nezworski, Stejskal, Garven, and West (1999) challenged Ganellen's (1996) characterization of the revised Rorschach Depression Index (DEPI; Exner, 1991) as a promising psychometric marker of depression that deserves serious attention by researchers and clinicians. To the contrary, however, a careful examination of existing studies indicates that no compelling empirical evidence exists indicating that Ganellen's conclusions should be modified at the present time, although no firm conclusions about the DEPI can be reached until further evidence accumulates. Furthermore, although Wood et al. (1999) suggested that evidence supporting the reliability and validity of the Rorschach in general is weak, ample evidence exists demonstrating that the Rorschach can be scored reliably (Meyer, 1997), that Rorschach variables in general have respectable levels of criterion-related validity (Bornstein, 1996; Hiller, Rosenthal, Bornstein, Berry, & Brunnel-Neuleib, 1999), and that the Minnesota Multiphasic Personality Inventory (MMPI; Hathaway & McKinley, 1943) and Rorschach have comparable levels of criterion-related validity, with the MMPI outperforming the Rorschach in certain respects and the Rorschach outperforming the MMPI in others (Bornstein, 1999; Hiller et al, 1999).
