Part I of this two-part study compared prospective counselors' scores on selected measuring instruments at the beginning of their course work and practicum experience, and later at the end of their practicum experience. Part II examined the effect of a course in group counseling techniques on prospective counselors' self concepts, self images, social images, and interpersonal relations. Subjects were counselor trainees at North Texas State University during the period from 1968 to 1970. Instruments used were the Rokeach Dogmatism Scale, the Philosophies of Human Nature Scale, the Test of Counselor Attitudes, and Personal Orientation Inventory and the Counselor Rating Blank. Post-test results indicated that trainees made significant positive gains toward self actualization, and that those who participated in intensive group counseling, particularly as group leaders, evidenced greater positive change than those who did not serve as leaders. It is hoped that data gained from this study may be useful in critically evaluating specific aspects of a counselor education program. (Author/CJ)
