The Effect of CS Administration or an R-Optimized Alternative on Potential Projective Material in Rorschach Responses From Six Studies and a Meta-Analysis of Their Findings

Abstract

The Rorschach Performance Assessment System (R-PAS; Meyer, Viglione, Mihura, Erard, & Erdberg, 2011 ) introduced R-optimized administration to reduce variability in the number of Responses (R). We provide new data from six studies of participants randomly assigned to receive a version of this method or Comprehensive System (CS; Exner, 2003 ) administration. We examine how administration methods affect 3 types of codes most likely to contain potential projective material and the frequency of these codes for the 1st, 2nd, 3rd, 4th, or last response to a card (R in Card). In a meta-analytic summary, we found 37% of responses have 1 type of code, 19% have 2 types, and 3% have all 3 types, with stable proportions across responses within cards. Importantly, administration method had no impact on potential projective variable means. Differential skew across samples made variability harder to interpret. Initial results suggesting differences in 3 of the 18 specific Type by R in Card pairs did not follow a coherent pattern and disappeared when using raw counts from all participants. Overall, data do not support concerns that R-optimized administration might alter potential projective processes, or make potentially "signature" last responses to the card any different in R-PAS than the CS.

Comparing the Validity of the Rorschach Performance Assessment System and Exner’s Comprehensive System to Differentiate Patients and Nonpatients

“…To assess between system differences in R for the patients, we generated descriptive analyses and compared M s using a t test with Cohen’s d as the effect size index. We also compared variability using SD proportions as the effect size index (dividing the R-PAS SD by the CS SD ) and its natural log to test significance (Hosseininasab et al, 2019; Meyer et al, 2020). We use d magnitudes ≥0.20 as the conventional benchmark for small mean differences.…”

“…Research comparing CS and R-PAS administration among nonpatients (Pianowski et al, 2021), experimental studies of participants receiving CS administration versus early versions of R-PAS administration (Hosseininasab et al, 2019;Meyer et al, 2020), and statistical modeling of R to convert its distribution in CS administration to fit its distribution in R-PAS administration (Meyer et al, 2011;Pianowski et al, 2016aPianowski et al, , 2016b all provide similar conclusions. R-PAS administration achieves its aim of slightly increasing the average number of responses in a protocol while dramatically decreasing its variability across respondents.…”
