Social support, self-management, and quality of life among participants in an internet-based diabetes support...

The purpose of this study was to evaluate the relationship of three social support measurement approaches to three criteria: (a) use of an Internet-based disease management system, (b) diabetes self-management, and (c) quality of life. An online survey was conducted among participants on the "D-Net" (Diabetes Network) website, which provided information and support for adults with diabetes mellitus: A total of 221 respondents completed (a) items from the Interpersonal Support Evaluation Checklist, a measure of general support; (b) the Diabetes Support Scale, a new measure of disease-specific informational, advice, and empathic support; and (c) the Chronic Illness Support Survey, a measure based on a social ecologic framework to assess support received for chronic illness management from six different sources (personal, family and friends, health care team, worksites and organizations, neighborhood and community, and media/public policy). Although the three measures were moderately intercorrelated (r = .26-.45), each was related to different aspects of D-Net use, diabetes management, and quality of life. These results remained significant after adjusting for demographic and medical condition factors (partial correlations of.15 to.33). This study illustrates the importance of a multidimensional approach to measuring social support and computer-mediated health outcomes. The advantages and disadvantages of applying these different conceptualizations of support in health promotion programs are discussed, and opportunities for future research are identified.
