The current study conducted a psychometric evaluation of the Participation Evaluation Rating Form (PERF), an exploratory session-by-session measure of group process which provides the intervention team’s quantitative and qualitative rating of each member’s performance. Relational Data Analysis (RDA) was used to analyze the psychometric properties of the PERF.

Inter-coder percent agreement among the TOC and TCC coders for each category level ranged from .87 to .95, being moderate to high. The Fleiss’ kappa across all category levels ranged from .53 to .83, indicating moderate to almost perfect agreement. The Pearson Correlations between the TOC and TCC ranged from r (40) = .969, p <.0001 at the second order levels of theoretical categories to r (40) = .824, p< .0001 at the first order levels. These findings indicate the RDA-PERF has acceptable reliability and validity, providing support for the use of this measure in future studies of group process.
