3.2 Health assessment questionnaires
Standardized health assessment using questionnaires improves patient-provider interaction by facilitating the patient’s input into the healthcare process [4,5]. A re-port of the status of a patient’s health condition that comes directly from the patient without interpretation of the patient’s response by a clinician or anyone else helps to assess the burden of disease and treatment from the patients’ perspective [22].
However, it can be assumed that using traditional paper-based questionnaires in a low literate patient population will not contribute to patient-provider interaction. In fact it may complicate the situation further. Possible mistakes made by the patient in completing the questionnaire may lead to invalid information. Moreover, the burden of having to complete a task which is hard to fulfil can lead to emotional strain, which makes it even harder for the patients to maintain themselves in the complex context of a health care setting.
Previous research in the USA, India and China has shown that smart deployment of ICT increases the ability of low literate patients to independently fill in health-related questionnaires [7-10,16], even if patients had limited or no computer skills [11]. These so-called Talking Touch Screens (TTS) added visual (pictures, videos) and auditory (speech) support to multiple choice questions which were shown one by one on a touch screen. In this way patients were able to see and hear the questions and accompanying visual materials. The patient responded to the questions by tapping the preferred answer on the touch screen.
Although effects on patient-provider interaction of these TTS’s have not been established yet, all findings so far indicate that they do increase the usability of questionnaires for low literate patients [6- 11, 23-25]. However, the potential of such tools might be increased by systematically taking into account evidence-based knowledge on designing smart support for self-reliance of low literate persons. Also, differences in the health care system as well as language and cultural differences between, on the one hand, the USA, India, China and, on the other hand, The Netherlands should be considered.
