Insights into the translation and adaptation of an instrument for measuring time processing abilities among individuals with visual and intellectual disabilities

Background: People with visual and intellectual disabilities frequently face challenges in daily time management. However, there is no validated instrument for assessing underlying time-processing abilities in Dutch-speaking individuals, in general nor for this specific target group. Aims: This study aimed to translate and adapt the KaTid®-Adult instrument, originally developed in Sweden, for application in this population in Belgium (Flanders) and the Netherlands. In addition, the goal was to make the instrument more accessible to people with visual impairments. Method: The researchers translated and adapted the KaTid®-Adult, following World Health Organization guidelines and conducted pilot tests. Results: This descriptive study explains expected and unexpected issues encountered during the translation and adaptation. Conclusions: The outcome is that the KaTid®-Adult-NL is a culturally relevant instrument for measuring time processing abilities in individuals with visual and intellectual disabilities in Belgium (Flanders) and the Netherlands. However, the KaTid®-Adult was not initially designed for people with a visual impairment. In this study, first steps were taken to make the instrument accessible to people with visual impairments.
