The validity of the Rorschach and the Minnesota Multiphasic Personality Inventory: results from meta-analyses
Article Abstract:
The validity of the Minnesota Multiphasic Personality Inventory (MMPI) is better than the Rorschach Test. The MMPI was able to explain 23% to 30% of the variance while the Rorschach could only explain 8% to 13% of the variance. There are no theoretical data to support the view that both tests would do well in actual use. In previous studies, two or three of the MMPI validity scales have been correlated with a criterion measure. It implies that the median effect size is zero if the other scales are unrelated to the criterion.
