The effectiveness of a motivational enhancement smartphone application promoting lifestyle improvement for brain health: A randomized controlled trial

Abstract

Multidomain lifestyle modification is considered an effective intervention for dementia prevention due to its multifactorial nature. Recognizing that participants’ activity adherence is crucial for successful lifestyle modification, our team developed a smartphone application to enhance motivation toward brain health behavior based on gamification theory, which influences behaviors by enhancing motivation. The developed smartphone application has two main functions: delivering supporting videos from family, friends, and medical staff, and self-evaluation. We assessed the effectiveness of this smartphone application with regard to brain health behavior. In this eight-week randomized controlled trial, 40 participants were randomly assigned to the smartphone application intervention group or control group. The primary outcome reflected participants’ brain health behavior in three categories: physical activity, cognitive activity, and healthy diet. Each brain health behavior was measured by the Korean version of the Global Physical Activity Questionnaire, Cognitive Activity Score, and Mediterranean DASH Intervention for Neurodegenerative Delay Diet Score. Furthermore, we investigated the change in motivation, measured by the Situational Motivation Scale. Additionally, we reviewed participants’ self-record diary during the first, fourth, and eighth week of intervention for evaluation of adherence. The intervention group was found to have a positive association with moderate metabolic equivalent activities (P = 0.01) and intrinsic motivation change (P = 0.01). There was a significant difference between the intervention and control groups regarding average physical activity at week 8 (P = 0.037). An eight-week intervention with the smartphone application induced physical activity of moderate intensity through intrinsic motivation enhancement. We suggest that the motivation enhancement application could be an efficient option for maintaining and promoting psychosocial health behavior. This smartphone application can be applied to any other disease that needs behavioral change. Through the application, a broader spectrum of the population, regardless of time, space, and human resources, can benefit from community health services.

Artificial Intelligence in Gamification to Promote Mental Health among University Students: A Scoping Review

“…(11,12,13) Así también, la gamificación se basa en teorías que se aplica como técnicas para cambiar el comportamiento de una manera específica, donde sus resultados son medibles. (14,15) La convivencia social sigue siendo una preocupación de la comunidad científica, pues la evolución de la tecnología trae nuevas incógnitas que deben ser resueltas por la necesidad de una mejor convivencia y salud mental basada en valores. (16) El propósito de esta investigación fue realizar una revisión de alcance de estudios que han utilizado la IA en la gamificación como estrategia lúdica para promover la salud mental en el entorno de la educación superior, de esta manera, este artículo plantea las siguientes preguntas de investigación: ¿Cuál ha sido el impacto de las estrategias de juego gamificadas en la promoción de la salud mental en la educación superior según la literatura existente?…”
