Regina Sonia Gattas F. do NascimentoWe examined the impact of the changes in administration and coding introduced by the Rorschach Performance Assessment System (R-PAS) relative to the Comprehensive System (CS) on the Rorschach response process, as manifested in variables relevant to interpretation. We also examined the efficiency of each system to obtain protocols in an optimal range of responses (R) for interpretation. As hypothesized, when comparing 50 CS and 50 R-PAS nonpatient protocols, R-PAS produced many more protocols in the optimal R range (18-27) than the CS (78% vs. 24%) and it eliminated the need for re-administration, which was required for five CS protocols. As expected, R was less variable with R-PAS, as were two variables derived from it, R8910% and Complexity. In addition, as expected because of different Form Quality tables, R-PAS showed notably fewer and less variable perceptual distortions than the CS, and an increase in more conventional perceptions. The other 58 variables showed no reliable differences in means or standard deviations, though modest power precluded definitive inferences about equivalence. Overall, our results support previous findings about the benefit of R-PAS to obtain protocols in an optimal range for interpretation, while keeping the core manifestations of the response process unchanged.
