Face and contents validity, and feasibility of Healthometer: a Delphi study

Our recent descriptive report in this journal of "Healthometer", an interactive instrument for self-mediated health counseling, was well received in the medical systems research and development community. Suitable for paper as well as electronic mediation and covering both screening, processing/storage, and advisory tasks in a positively reinforcing and confidential way, it has on the whole been considered to be an interesting model in the advancing "information society technologies" perspective; however, a closer scientific and operative evaluation is warranted. Because the power of the instrument in addition to the hardware is critically dependent upon the wet- and software quality, the present study aims at examining in the same forefront forum some basic aspects of all these modalities, with emphasis on face and content validity, feasibility, and users' attitudes and opinions. It can be summarized, quite briefly, that all of them were satisfactory.
