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.
