ObjectiveSerious games can serve as easily accessible interventions to support siblings of children with disabilities, who are at risk of developing mental health problems. The Dutch serious game ‘Broodles’ was developed for siblings aged 6–9 years. The current study aims to assess the cultural applicability, desirability, feasibility, and acceptability of ‘Broodles’ in Norway. MethodsNorwegian siblings (N = 16) aged 6–13 years and parents (N = 12) of children with intellectual disabilities assessed the game. Their feedback data from interviews and questionnaires were sorted using a model of engagement factors in serious games. ResultsAt pre-use, participants showed interest in the game, and after initial use the participants were overall positive about the format, content and objectives, including validation of emotions and recognition. The participants had suggestions for improved engagement and feasibility. ConclusionThe game was found to be culturally applicable, desirable and acceptable, although Norwegian translation is necessary for further evaluation. Recommendations to enhance engagement were provided, including suggestions to play the game with parents or in a group. InnovationThis initial assessment of the serious game Broodles in a non-Dutch setting shows promise for an innovative way of supporting siblings of children with disabilities.
