A Study on Habits and Personality Traits: With Ko\'s Basic Habits and the Basic Personality Traits of Eysenck et al. as the Variables

Some of the senior high schools are top ranked and some are bottom ranked and the rest are middle ranked in the academic quality of the school as a whole. The data obtained were analyzed using the stepwise multiple correlation analysis; Firstly the analysis was applied to the data obtained from the eight subscales of the 16PF, and secondarily to the data from the 14 subscales of the Study Habits Questionnaires, and finally to the data from both the 16PF and the Study Habit Questionnaires.

The results revealed (i) that the study habit scores are significantly superior to the 16PF scores in predicting the academic achievement of senior high school students, implying that the concept of study habits is a much better than that of personality traits, at least in the task of predicting academic achievement of the senior high school students; and (ii) that some of the16PF scores are complementary to study habit scores in making a better prediction of academic achievement of the senior high school students.

In order to find out the answer to the second object of the present study, the 240 items of the Neo PI-R Form S were analyzed itemwise according to the basic structure of habit items as described by the present researcher. The results of the analysis revealed that about 56% of items in the Neo PI-R Form S are written exactly in the basic form of a typical habit test item as described by the present researcher previously.

Further-more, it was found that some scale of the Neo PI-R Form S even contained 100% of habit-type items. The present investigator, therefore, proposed that in the future study, the basic or stereotyped form of personality traits item be clearly defined, so that every personality inventory should contain only the test item which is clearly different from the habit item style but perfectly fits to the basic form of the personality traits.
