This quantitative study examines whether the English screening tool ”Adult Reading History Questionnaire” works in a Swedish context or not. The essay is based on a formation of a new screening tool called ARHQ-vux. The intention was to find out whether a person might be dyslectic or not. ARHQ-vux is based on components such as heredity factors and how the informants experienced school as a child. The screening tool was tested in a sample of 71 adult students at five different adult educational institutions in the north of Sweden. To measure the validity a correlation was made between ARHQ-vux and the already standardized Swedish screening tool DUVAN. This study shows that the tool ARHQ-vux successfully can be used as a reliable screening tool to identify adults who might be at risk of dyslexia.
