title: Smartkuber: A Serious Game for Cognitive Health Screening of Elderly Players.
abstract: OBJECTIVE
  The goal of this study was to design and develop a serious game for cognitive health screening of the elderly, namely Smartkuber, and evaluate its construct, criteria (concurrent and predictive), and content validity, assessing its relationship with the Montreal Cognitive Assessment (MoCA) test. Furthermore, the study aims to evaluate the elderly players' game experience with Smartkuber.
  
  
  METHODS
  Thirteen older adults were enrolled in the study. The game was designed and developed by a multidisciplinary team. The study follows a mixed methodological approach, utilizing the In-Game Experience Questionnaire to assess the players' game experience and a correlational study, to examine the relationship between the Smartkuber and MoCA scores. The learning effect is also examined by comparing the mean game scores of the first and last game sessions of each player (Delta scores).
  
  
  RESULTS
  All 13 participants (mean age: 68.69, SD: 7.24) successfully completed the study. Smartkuber demonstrated high concurrent validity with the MoCA test (r = 0.81, P = 0.001) and satisfying levels of predictive and content validity. The Delta scores showed no statistically significant differences in scoring, thus indicating no learning effects during the Smartkuber game sessions.
  
  
  CONCLUSIONS
  The study shows that Smartkuber is a promising tool for cognitive health screening, providing an entertaining and motivating gaming experience to elderly players. Limitations of the study and future directions are discussed.
