# A Randomized Controlled Trial of an Enhanced Version of a Cognitive–Behavioral Video Game Intervention Aimed at Promoting Active Aging: Assessments of Perceived Health and Healthy Lifestyle Habits at Pre- and Post-Intervention

## TL;DR

A video game-based cognitive-behavioral intervention improved health perceptions and healthy habits in older adults.

## Contribution

An enhanced cognitive-behavioral video game intervention was tested for promoting active aging in older adults.

## Key findings

- The CBI-V group showed significant improvements in general health, mental health, sleep hygiene, physical activity, and eating habits.
- Participants in the CBI-V group reported higher clinically significant changes in health and lifestyle metrics.
- High satisfaction scores were reported by participants using the video game intervention.

## Abstract

Background/Objective: Video games offer an innovative tool for delivering active aging interventions. The objective of this study was to analyze the efficacy of an enhanced version of a cognitive–behavioral intervention to promote active aging, administered through a video game, on perceived health and healthy lifestyle habits. Methods: A total of 556 participants aged 45 or older (74.3% women, mean age of 60.8 [SD = 8.0]) were randomly assigned to a cognitive–behavioral intervention to promote active aging administered via an interactive, multimedia, online, and serious video game with a complementary smartphone app (CBI-V; n = 279) or to a control group receiving non-specific online information (CG; n = 277). Perceived health (General Health, Body Pain, Physical Functioning, Physical Role, Vitality, Social Functioning, Emotional Role, Mental Health, Physical and Mental Summary Indices); healthy habits, including sleep hygiene behaviors, physical activity, and eating habits; dropouts; adherence to the intervention (completed modules; total playtime; time devoted to cognitive training; number of cognitive task attempts and tasks completed between modules); and satisfaction with the intervention were assessed by independent, blind evaluators via an online platform before and after the intervention. Results: At the post-intervention, the CBI-V group obtained significantly better scores in General Health (p < 0.001), Mental Health (p = 0.015), sleep hygiene (p < 0.001), physical activity (p = 0.024), and eating habits (p = 0.001) than the CG. The effect sizes were small (d = −0.188 to 0.334). Clinically significant changes were higher in the CBI-V group than in the CG in General Health (p = 0.029), Physical Function (p = 0.028), Social Function (p = 0.011), Emotional Role (p = 0.008), Mental Health (p = 0.026), Physical Summary Index (p = 0.010), sleep hygiene (p = 0.020), and eating habits (p = 0.019). Participants reported a high level of satisfaction with the intervention, with a mean score of 25.4 (SD = 4.0) out of a maximum of 32 on the intervention satisfaction measure. Conclusions: These findings support the efficacy of a cognitive–behavioral video game intervention in enhancing perceived health and promoting healthy lifestyle habits among people aged 45 and above.
