Based on the recommendations of Baity and Hilsenroth (1999), this study fur
ther investigated the reliability and validity of the Rorschach Aggressive
Content (AgC) variable developed by Gacono and Meloy (1994). Eighty-five ag
gressive objects identified by Gacono and Meloy, 19 potentially aggressive
objects and 22 neutral (nonaggressive) objects were rated for aggressivenes
s based on the definition of AgC. Two hundred seventy-six participants rate
d objects on the Object Rating Scale (0-6), where a score of 0 indicates th
at an object does not fit the definition of AgC. In addition, objects rated
a 4 (moderately aggressive) or higher were then classified into 5 qualitat
ive groupings (weapons, animal/part of animal, environmental danger, fictio
nal creature, and other). Analysis of the results indicates that the AgC li
st can be replicated and that objects rated as at least moderately aggressi
ve (4) can be reliably classified into distinct categories. One-month test-
retest reliability (r = .99) suggests that objects can be scored consistent
ly using the definition of AgC and provides support for the utility of the
AgC variable. Based on the results of this study, recommendations for the a
ddition of the AgC variable to the list of content categories of Exner's (1
993) Comprehensive System are presented and discussed along with scoring ex
amples.
