正常者および精神分裂病者における抹消作業検査の因子分析的研究

抄録

The present study was so designed as to compare scores of the measures of the cancellation testsuch as amount of performance before resting (A) and after resting (B), error rate,(A & B), efficiency (A & B), rate of the resting effect, and ratios of omitted numbers of 3, 6 and 8 which were set to be crossed out, in schizophrenic subjects (8) with those in normal subjects (N). Besides scores of the measures of the. Uchida-Kraepelin test such as type of work curve, amount of performance (A & B), error rate (A & B), and rate of the resting effect were added, and then the structure of factors based on correlation coefficients of these scores in Ss was compared with that in N.
The results were as follows:
1) Differences of mean scores of amount of performance (A & B), error rate (A & B), efficiency (A & B) in S and those in N were statistically significant, but there were no differences between S and N in mean scores of rate of the resting effect, and ratios of omitted numbers.
2) Four factors were extracted and rotated in S and N respectively. In S they were tentatively named as good-bad of performance of both cancellation test, and Kraepelin test, good quantity of cancellation test and bad quality of Kraepelin test, good quantity of Kraepelin test and bad quality of can tion test, and ratios of omitted numbers of 6 and 8, and in N as good-bad of performance of both tests, good quantity of cancellation test and bad quality of Kraepelin test, resting effect, and ratios omitted numbers of 6 and 8.
3) There might be little value as a psycho diagnostic measure in rate of the resting effect of cancellation test, and it seemed it was not necessary to measures distinguishing before the resting from after the resting.
