The aggression response and the Rorschach.

We propose the addition of four aggressive indices for Rorschach scoring: aggressive content, aggressive potential, aggressive past, and sado-masochism scores. Interrater agreement is presented and ranges from 92-100%. Nomothetic comparisons are made between groups with higher base rates for violence with mixed results, although the sado-masochism frequency was significantly higher in severe psychopaths than in moderate psychopaths. Idiographic use of the aggression indices is emphasized, with a particular focus upon inferring the quality, intensity, and directionality of intrapsychic aggression in relation to self and object representations.
