ABSTRACT
In the alcohol test for drunken criminals, we introduced Bender-Gestalt test and Rorschach test for the assessment, and examined their usefulness for the evaluation of intoxication patterns according to Binder's classification. The subjects were 24 drunken criminals who were examined by Mental Hygiene Group, Tsukuba University, for psychiatric evidences. The subjects were divided into the ordinary intoxication group (OI group) and the complicated intoxication group (CI group) on the basis of the behavioral assessment, and the psychological tests were performed before and after drinking. The following results were obtained. 1) Alcohol intoxication induced decrease in R1T, W and VIII + IX + X/R and increase of BGT scores and P%, which indicates that subjects become unable to make comprehensive and delicate responses to the external stimuli. 2) When we classified subjects into increasing and decreasing type on the pattern of changes in the BGT score from before to immediately after drinking in each subject, we found the ratio of increasing type in complicated intoxication is more than in ordinary intoxication significantly. And we found significant group x drinking interaction in F+% and At% of Rorschach test. The F+% significantly decreased only in CI group. The At% in CI group tended upward, but downward in OI group. These findings indicated that complicated intoxication reduced the subject's reality testing, while not in ordinary intoxication. 3) Comparing the effects of personality and intoxication factors in complicated intoxication, intoxication factors were considered to play primary roles. 4) We found association between high BAL and reduction of ego function and imagination, which is represented as significant peak of BALx drinking interaction in the BGT scores, M and FM + m. These observations suggest that the psychological tests as part of the alcohol tests are useful for the evaluation and research of intoxication.
