This study examined differences in participants' perceptions of their Character Development, Leadership, and Environmental Service prior to and immediately following participation in a North Carolina Outward Bound School (NCOBS) course using the NCOBS Course Impression Survey (NCOBCIS). The three-fold purpose of this study was to confirm the "a priori" factor structure of the NCOBSCIS, assess true change in participants' scores following completion of an NCOBS course, and to investigate questions that emerged in the quantitative data that could be better explained by qualitative analysis. Quantitative results indicated improvements in Character Development and Environmental Service. This study furthers our understanding of the NCOBSCIS using a true pre-post design, provides further evidence of the validity and reliability of the NCOBSCIS and its factor structure, and the qualitative inquiry enhances our understanding of the potential influence of program participation.
