The purpose of this study was to measure the degree of behavioral change in terms of some aspects of the psychological self resulting from participation training of groups from two churches. Attempt is made to describe and measure the process of growth in terms of a process model categorized into awareness, acceptance, and affirmation. Content data were gathered by the Semantic Differential Technique which measured changes in the meaning of selected concepts on nine bipolar, adjective scales. The test was given on a pre-test and post-test basis. Process was measured by the use of a journal questionnaire which provided information for the three-step process model: frustrations showed up mainly on the conceptual level, whereas rewards of participation were more on the process or experiential level. The participants came to be less afraid of controversy and placed a higher value on tension but were less afraid of it. Adventure and joy became powerful as concepts, communication was improved, and certain philosophical concepts such as death were less feared. (author/nl)
