The Validity of the Holtzman Inkblot Technique: New Indices

Objective: The present study examines the validity of 11 new Holtzman Inkblot Technique indices. These were chosen from Exner’s Comprehensive System (RCS) indices using two criteria: first, they had to be valid according to meta-analysis, and second, they must be computed using the HIT standard scoring system. Methods: Both techniques were administrated with a retest interval from 1 to 7days to a sample of 139 subjects (63 males and 76 females) from the general population. The validity of the new indices was studied through Pearson correlation (r) with the corresponding RCS indices. Results: Nine of the 11 new indices (R-HIT, F%-HIT, M-HIT, m-HIT, C'-HIT, Blends-HIT, PureH-HIT, DQ+HIT, and X-%-HIT) showed significant correlations with Rorschach scales, confirming our hypotheses. The correlation ranged from a minimum of 0.144 to a maximum of 0.414. Conclusions: The results provide support for the validity of the new HIT indices and have important implications for both clinical and research fields.
