Description: The Holtzman Inkblot Technique (HIT) is a multi-variable projective personality test that was designed to overcome psychometric limitations of the Rorschach.

Scoring: The HIT is an inkblot test that consists of two alternate forms of 45 inkblots. It is scored on 22 variables. These are: reaction time, rejection. Location, space, form definiteness, form appropriateness, color, shading, movement, pathognomic verbalization, integration, content (human, animal, anatomy, sex, abstract), anxiety, hostility, barrier, penetration, balance, and popular. Administration and scoring are rather time consuming, except in computerized versions.

Reliability: The author reported intrascorer consistency on three examiners after a period of about 3 months. These reliabilities average about .95 on 9 scores. Interscorer consistency is reported for a number of different scorers for various scores. The lowest reported score reliabilities are .57, the highest .99. Intrasubject reliabilities are reported for 15 different groups on all 22 scores. These split-half reliabilities vary widely, but generally range between .50 and .90 with an approximate average in the .70s or .80s. No test-retest reliabilities w ere found which might furnish information about whether the scores are measuring persisting traits.

Validity: Information regarding validity does not appear in the manual.

Norms: College students, average adults, 7th graders, elementary school children, 5-year olds, chronic schizophrenics, mental retardates, and depressed patients.

Suggested Uses: Recommended uses of the Holtzman Inkblot test include experimental and clinical applications.
