title: Temporal stability in the Rorschach method: a meta-analytic review.
abstract: The temporal stabilities of the Rorschach method scoring systems were investigated. A comprehensive literature search was conducted to find all test-retest studies, both regular and from control samples in therapy evaluation studies. Meta-analyses were conducted for samples, individual entries, and variables in 36 samples. Separate analyses were made for 10 samples using the Comprehensive System (CS; Exner, 1993). The temporal stability was high, especially those obtained from regression model predictions. The CS consistently shows higher stability than other systems, whereas increasing retest intervals leads to decreasing stability. Shortcomings of the available studies are highlighted and discussed, and recommendations are given for design and methodology.
