title: Community health behavior change through computer network health promotion: preliminary findings from Stanford Health-Net.
abstract: Computer-based health education has been employed in many settings. However, data on resultant behavior change are lacking. A randomized, controlled, prospective study was performed to test the efficacy of Stanford Health-Net (Stanford, CA, U.S.A.) in changing community health behaviors. Graduate and undergraduate students (N = 1003) were randomly assigned to treatment and control conditions. The treatment group received access to Health-Net, a health promotion computer network emphasizing specific self-care and preventive strategies. Over a 4-month intervention period, 26% of the treatment group used Health-Net an average of 6.4 times each (range 1-97). The most commonly cited reasons for use were curiosity, general health education, evaluation of current symptoms and anonymity of information. Users rated Health-Net favorably. The most commonly reported reasons for non-use were related to lack of health problems, limited time and lack of access to computer facilities. The mean number of ambulatory medical visits decreased 22.5% more in the treatment group than in the control group (P less than 0.05), while hospitalizations did not differ significantly between groups. In addition, perceived self-efficacy for preventing the acquisition of a sexually transmitted disease (STD) and herpes increased 577% (P less than 0.05) and 261% (P less than 0.01) more, respectively, in the treatment group than in the control group. These findings suggest that access to Stanford Health-Net can result in significant health behavior change. The advantages of the network approach make it a potential model for other communities.
