Test-retest reliability of the Rorschach on neurologically impaired subjects

Pairs of Rorschach protocols for each of 25 neurologically impaired patients were obtained from two different testings spanning an average of three years apart to study the Rorschach's test-retest reliability under specific conditions. Significant correlations were obtained for all but a few major summary scores. An additional analysis revealed no strong relationship between the varying test-retest interval lengths and the stability of various Rorschach scores.
