We provide a meta-analytic review of interrater reliability for scoring the 2 most commonly studied Rorschach (2003) Exner, J. 2003. The Rorschach: A Comprehensive System, , 4th ed, New York: Wiley. [Google Scholar] aggression measures: (a) The Elizur (1949) ∗Elizur, A. 1949. Content analysis of the Rorschach with regard to anxiety and hostility. Rorschach Research Exchange and Journal of Projective Techniques, 13: 247–287. [Google Scholar] Hostility Scale and its main derivative scoring systems (Holtzman, Thorpe, Swartz, & Herron, 1961 ∗Holtzman, W. H., Thorpe, J. S., Swartz, J. D. and Herron, E. W. 1961. Inkblot perception and personality: Holtzman Inkblot Technique, Austin: University of Texas Press. [Google Scholar]; Murstein, 1956 ∗Murstein, B. 1956. The projection of hostility on the Rorschach and as a result of ego-threat. Journal of Projective Techniques, 20: 418–428. [Google Scholar]) and (b) Holt's (1977 Holt, R. 1977. “A method for assessing primary process manifestations and their control in Rorschach responses”. In Rorschach psychology, Edited by: Rickers-Ovsiankina, M. A. 375–420. New York: Krieger. [Google Scholar], 2005 Holt, R. 2005. “The Pripro scoring system”. In Scoring the Rorschach: Seven validated systems, Edited by: Bornstein, R. F. and Masling, J. M. 191–235. Hillsdale, NJ: Lawrence Erlbaum Associates. [Google Scholar]) aggression variables. Substantial reliability was observed for both Elizur's hostility score (e.g., weighted mean summary score correlation = .91, N = 1,279) and Holt's aggression variables (e.g., weighted mean summary score correlation = .84, N = 226). These meta-analytic data suggest that like the contemporary variables included in Exner's Comprehensive System or Gacono and Meloy's (1994) Gacono, C. B. and Meloy, J. R. 1994. “The aggression response”. In The Rorschach assessment of aggressive and psychopathic personalities, Edited by: Gacono, C. B. and Meloy, J. R. 259–278. Hillsdale, NJ: Lawrence Erlbaum Associates. [Google Scholar] extended aggression scores, the historically important Elizur scoring systems and Holt aggression variables can be scored reliably.
