Researchers developed an instrument based on definitions of the variables of self-esteem, self-awareness, self-assertion, and acceptance of others to be used as outcome criteria to define and measure the outcomes of the Colorado Outward Bound School experience and to determine if the outcomes were caused by the program. The Outward Bound course lasted three weeks, during which participants studied survival skills and engaged in various wilderness experiences. Each of 620 participants was assigned to one of 3 courses and, randomly, to one of 11 groups. Each participant received an evaluation instrument to complete. Data indicated that Outward Bound had a positive impact on the participants' self-assertion. It also affected the level of self-esteem, although this effect was not found in all courses. There was weak evidence that the program affected the participants'acceptance of others. The study failed to show any impact on self-awareness. In a written observation, a program participant described his initial fears, the self-confidence gained through training and actual experience, the reactions of others in the group, and, finally, his positive feelings about himself because he had persevered.
