About this study
Official title: Quality of Self-Diagnosis by Headache Patients Getting Tailored Internet Information - Part 2
Medical expert systems in combination with portal searching meta-search engines are exploited to provide reliable patient-tailored information. A prototype of a web-based information system has been developed and is to be evaluated. Its aim is to answer the decisive question whether expert system guided internet meta-search provides a better information supply for patients seeking health information online then this is possible by using ordinary search engines or health portals. The research does neither investigate the influence of ethical nor legal aspects of internet health information supply.
Read the detailed description
The study is a follow-up of NCT00746408. It has been conducted because for the first study still not enough participants have been recruited. The study took part at Bamberg University in Germany with 140 participants.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Intervention 1 | Participants using the prototype to receive expert system guided tailored internet information about the type of headache of a family member who provided anamnesis data for a common kind of headache. | |
| Control 1 | Participants using search engines and portals to gather internet information about the type of headache of a family member who provided anamnesis data for a common kind of headache. | |
| Intervention 2 | Participants using the prototype to receive expert system guided tailored internet information about the type of headache of a family member who provided anamnesis data for a less common kind of headache. | |
| Control 2 | Participants using search engines and portals to gather internet information about the type of headache of a family member who provided anamnesis data for a less common kind of headache. |
