Usability of Behavioural Recording Application ( <scp>BRA</scp> ) for Coping With Behavioural and Psychological Symptoms of Dementia

This study developed the Behavior Recording Application (BRA) based on Applied Behavior Analysis (ABA) to support non-pharmacological interventions for Behavioral and Psychological Symptoms of Dementia (BPSD), and examined its usability among care professionals. Thirty-one care staff members from elderly care facilities in Japan used the application during ABA-based consultations and evaluated its usability using a 10-item Likert scale. While overall ease of use was rated positively, differences were observed in participants' willingness to use it regularly and in their perception of how much they needed to learn to use it effectively. Stepwise multiple regression analysis using the Akaike Information Criterion (AIC) identified age, caregiving experience, and digital device usage as significant predictors of usability. These findings suggest that although BRA demonstrates good usability, additional support may be necessary for care professionals of advanced age, with less experience, or with limited digital proficiency.
