Process and Outcome Evaluation of a Social-Networking Website for Health Promotion
type: CreativeWork
description: Overweight and obesity pose a significant threat to the health and wellbeing of college students. However, studies of interventions to improve the health behaviors of college students are few in number, largely atheoretical, and have limited potential for widespread dissemination. The goal of this study was to evaluate a pilot of an internet based social-networking intervention to promote health behavior change. Specific aims were to assess the role of behavioral engagement as a mechanism of change over time, review qualitative feedback regarding participants' likes and dislikes of the website, and use social networking analysis (SNA) to analyze structural support and its effects on behavior change. The sample consisted of 39 students from the Loma Linda University School of Public Health. Participants each selected a specific health behavior goal that they wished to achieve in the 10-week period of the study and completed the web-based individual health behavior change project as part of the coursework. Results showed a significant improvement in participant health behavior across the course of the study period. Results also indicated that level of peer feedback and support received significantly moderated change in health behavior across time such that greater improvement in health behavior was observed in those who received a greater amount of peer feedback. Qualitative analysis revealed participants reported the features of peer feedback, personal blog, and line graph of heath behavior change to be the most helpful. The most commonly reported frustrations were website technical difficulties, particularly at the start of the study. The SNA showed that indegree (number of ties received) and, to a lesser extent, outdegree (number of ties originated with another) predicted attainment of clinically significant change. Furthermore, examination of the structural network diagram revealed that more concentrated sets of reciprocal ties existed among participants who attai…
