Laaggeletterdheid en vragenlijsten: aanbevelingen van een participatief onderzoek met ervaringsdeskundigen

In research, we often use validated questionnaires to measure behaviour and health in the population. In the Netherlands, an estimated 2.5 million people aged 16 or older are low-literate, of which many experience problems when filling out complex questionnaires. As a result, we may not have an accurate view of their health. This article describes our experiences of working with experts-by-experience from the Stichting Lezen en Schrijven (Foundation for Reading and Writing) to improve the SF-12 questionnaire. This resulted in insights to make questionnaires more suitable for low-literate populations.
