The quality of interactive computer use among HIV-infected individuals.

This study examined how HIV-infected individuals used an interactive health software package called CHESS (Comprehensive Health Enhancement Support System). CHESS packages information and support in a variety of ways; the research examined how a subset of users whose posttest scores in a larger randomized trial showed significant improvement in quality of life compared on use patterns of CHESS with those who did not improve. The evidence presented here points to the nature of CHESS use more than it does to the amount of CHESS use. Those whose quality of life improved were among the most involved in their use of CHESS information tools. That is, even though Discussion Group accounted for the majority of all CHESS uses and time spent with the system, total use and Discussion Group use appeared less important than use of the information tools, especially if that use was at least somewhat sustained and involved.
