Board Game-Based Training on Community Mobility of Mobility Device Users: A Validation Study.

Obstacles and barriers in real-world settings can limit community participation for mobility device users. Effective training requires foundational device skills and realistic scenarios to help mobility device users anticipate and respond in real time. The HERL-Town is an educational board game designed to provide training on community transportation for mobility device users and other stakeholders. This study aimed to validate two game elements: transportation scenarios and a series of response options, respectively representing real-life transportation barriers and corresponding strategies to address these challenges. Through a nationwide online survey, Item-level Content Validity Index of 60 scenarios and preference for each of the four response options per scenario were rated by mobility device users and travel companions. A total of 126 individual participated in the study. Two scenarios did not satisfy the Item-level Content Validity Index standard (i.e., 0.78) were removed and 58 were retained. While most preferred (i.e., 1 st ranking) and least preferred (i.e., 4 th ranking) answers were consistent across participants, preference for the middle rankings (i.e., 2 nd and 3 rd tended to vary). Finalized scenarios and ranked response options can be applicable as game elements that simulate transportation barriers and facilitate discussions on safe and independent community mobility of mobility device users.
