Design and Usability of a Digitalized Compensatory Goal Management Training for Individuals with Brain Injury: A User-Centered Approach

Although there is more evidence in neuropsychological rehabilitation for transfer of treatment effects to daily life when using compensatory strategy training, computerized programs for patients with acquired brain injury still focus on function training. Therefore, we developed Karman Line Plan, a digitalized version of an evidence-based compensatory Goal Management Training intervention for individuals with brain injury and executive function problems. Karman Line Plan consists of a digital environment (Plan Game) and a mobile application (Plan Tool). This study aims to describe the design process and evaluate the usability and acceptance of Karman Line Plan. The program was developed using a three-phase standardized user-centred design approach. Results indicate that Karman Line Plan is perceived as user-friendly and valuable by both patients and therapists. The findings emphasize the importance of involving the target patient population early in the development process to allow for early adjustments and meet end-user needs.
