Objective: In recent years, an increasing number of gamification tools have been developed for older adults; however, few studies have explored the acceptability of these tools after initial use and sustained use in older adults. In the current study, we focus on "FISHERMAN," an executive function training game containing a cognitive game and an exergame, with the aim of investigating and comparing the acceptability of both versions of "FISHERMAN" after initial use and 3 months of sustained use in older adults. Materials and Methods: Seventy-six older adults were randomly assigned to the cognitive game training group or the exergame training group. Participants completed two 1-hour sessions per week for 12 weeks. Acceptability was evaluated through a validated, 7-point, self-rating, Interactive Technology Art Installation Technology Acceptance Model Questionnaire after the first and last training sessions, with higher ratings representing higher acceptability. The questionnaire included 22 items and 9 acceptability dimensions: usage behavior, intention to use, perceived usefulness, perceived ease of use, perceived playfulness, subjective norm, image, output quality, and result demonstrability. Descriptive statistics were conducted to evaluate acceptability after initial and sustained use. Two-way (time: initial use and sustained use; group: cognitive game group and exergame group) repeated ANOVAs were conducted to investigate the differences in acceptability. Post hoc, within-group, paired-sample t test analyses were performed to evaluate changes in game acceptability for each group over time. Results: After initial use and 3 months of sustained use, the average scores for overall acceptability and individual dimensions exceeded 5.5 of 7 points in both groups. The two groups presented different changes from initial use to sustained use. The overall acceptability, usage behavior, perceived usefulness, and perceived ease of use were significantly improved after training within the cognitive game group, while perceived playfulness was significantly reduced within the exergame group. Conclusions: The current study provided preliminary evidence that older adults had high acceptability for both the cognitive game and exergame versions of "FISHERMAN." After sustained use, acceptability of the cognitive game increased and acceptability of the exergame decreased, highlighting the importance of assessing game acceptability after initial and sustained use.
