Abstract

A review of the research literature dealing with outdoor rehabilitation programs produced the observation that all of the available research incorporated non-probability sampling techniques. The purpose of this paper was to assess the representativess of subjects who volunteer for participation in outdoor rehabilitation programs..The study design involved the comparison of a group of volunteers (N=10) to a control group of all non-volunteers (N=S3) before and after an outdoor rehabilitation program. The subjects were adult males who were interned at a Kentucky state prison farm. The instrument used was the self concept portion of Bills' Index of Adjustment and Values.The data indicated that: (1) major differences existed between the two groups at the time of the pretest, and (2) during the course of the study the e'xperimental group showed a considerable negative change in self concept while the control group remained reasonably stable. From these results, the author concludes that generalizing findings based on programs using volunteers to settings where the clients do not volunteer is extremely problematic..
