  • The Relationship Between Sense of Community and Job Satisfaction Among Campus Recreation Center Employees

    by Mina Woo, Incheol Jang, Yun Chang

    Research on the experience of campus recreation participants has been studied extensively. However, scholars have paid relatively little attention to employees of campus recreation. This study examined the relationship between Sense of Community (SOC) and job satisfaction of employees in Campus Recreation Center (CRC), and the impact of demographic information, including job classification and tenure, on the levels of their SOC and job satisfaction. Survey data were collected from CRC employees, including student employees, graduate assistants, part-time and full-time employees. Results indicated a positive relationship between SOC and job satisfaction that employees experienced. Even though results did not suggest the influence of employee's job classification and tenure on the levels of SOC and job satisfaction, it was found that job classification influenced three of nine factors of job satisfaction (e.g., fringe benefits, operating conditions, and coworker).


  • Measuring Biophysical and Psychological Stress Levels Following Visitation to Three Locations with Differing Levels of Nature

    by Yun Chang, Alan Ewert, Lisa M. Kamendulis, Barbara A. Hocevar

    Visitation to natural environments has been linked to psychological stress reduction. Although most stress-related research has relied on self-report formats, a growing number of studies now incorporate biological stress-related hormones and catalysts, such as cortisol and α-amylase, to measure levels of stress. Presented here is a protocol to examine the effects on levels of biophysical and psychological stress following visitation to three different locations with differing levels of nature. Biophysical and self-reported psychological stress levels are measured immediately upon entering the selected locations and just prior to the visitors leaving the site. Using a "drool" method, the biophysical measure consists of 1-2 mL samples of saliva provided by study subjects upon entry to one of three study locations. As prescribed by extant literature, the saliva is collected within a 45 minute time frame following the end of the visitor’s engagement at the location. Following saliva collection, the samples are labeled and transported to a biological lab. Cortisol is the biophysical variable of interest in this study and measured using an ELISA process with a TECAN plate reader. To measure self-reported stress, the Perceived Stress Questionnaire (PSQ), which reports levels of worry, tension, joy, and perceived demands. Data are collected at all three sites in the late afternoon through early evening. When compared across all three settings, stress levels, as measured by both the biological markers and self-reports, are significantly lower after visitation to the most natural setting.


  • The impact of short-term adventure-based outdoor programs on college students’ stress reduction

    by Yun Chang, Curt Davidson, Seann Conklin, Alan Ewert

    This study examines the effect of short-term adventure-based outdoor programs (AOP) on reducing college students’ stress levels. The effects of sex and different outdoor adventure activities in stress reduction are also evaluated. Thirty-three college students participated in selected short-term backpacking, canoeing, and kayaking programs. Student's salivary samples were collected to evaluate physiological stress response (as measured by levels of cortisol) and their psychological stress levels were collected through a modified 12-item questionnaire. Stress responses were measured at three different time points, including the second weekly meeting in the classroom, before the field trip, and at the conclusion of the field trip. Findings suggest that short-term AOP affords opportunities for college students to be away from daily challenges, and in turn reduce college students’ psychological stress levels and provide a temporary relief of physiological stress levels. No significant differences in college students’ stress levels were found between sex and different outdoor adventure activities.

    Levels of Nature and Stress Response

    by Alan Ewert, Yun Chang

    A growing number of studies have shown that visiting green spaces and being exposed to natural environments can reduce psychological stress. A number of questions concerning the effects of natural environments on levels of stress remain including, “Are activities engaged in natural environments more or less beneficial at reducing stress when compared to those done in more urban settings?” This study examined this question from the perspective of “levels of nature”. That is, data on levels of stress were collected from three sites, one site having wilderness-like characteristics, a second site representing a municipal-type park, and a third site representing a built environment (indoor exercise facility) within a city. Data were generated using biophysical markers (cortisol and amylase) and a psychological measure within a pre- and post-visit format. Findings suggest that visiting natural environments can be beneficial in reducing both physical and psychological stress levels, with visitors to a natural environment reporting significantly lower levels of stress than their counterparts visiting a more urbanized outdoor setting or indoor exercise facility.
