As the final part of a three-part evaluation of Colorado Outward Bound summer programs, a control group and an experimental group were evaluated on the four outcome variables of self-esteem, self-awareness, self-assertion, and acceptance of others, and on school achievement the following year. Participants consisted of 34 paying students and 31 students on scholarship; there were 25 girls and 40 boys. All were randomly assigned to experimental and control groups for the 21 day Outward Bound course. The experimental group completed the Inventory on the final day of the course; the control group received the Inventory by mail at about the same time. For both groups, school achievement data were collected from high school counselors. That data consisted of the students' grade point average two semesters following the course, the number of extra-curricular activities participated in, leadership positions held, disciplinary actions, plans to attend college, absences, ability to get along with others, self-confidence, adjustment, and tolerance for others. Results of this study did not confirm results of the earlier study. There were no significant differences between experimental and control groups on self-esteem, self-awareness, or self-assertion. There was a significant negative effect on acceptance of others. Neither sex nor paying status had a significant relationship with the outcome variables. The student achievement measures demonstrated no effects due to the program. (CM)
