Engaging adolescents in a computer-based weight management program: avatars and virtual coaches could help

Area of Science:

• Digital Health
• Adolescent Medicine
• Behavioral Science

Background:

• Chronic weight management in adolescents presents significant challenges.
• Traditional computer-based interventions often lack engagement.
• Animated avatars and virtual agents offer novel approaches to support adolescent health behaviors.

Purpose of the Study:

• To explore the acceptance and desire of adolescents to interact with animated avatars and virtual agents.
• To assess the potential of these digital representations in computer-based interventions for chronic weight management.
• To understand user preferences for virtual character design and functionality.

Main Methods:

• Community-based participatory research approach.
• Two-phase data collection: focus groups with adolescents, interviews with providers and parents, and prototype assessment.
• Involved multiple stakeholder groups including adolescents, parents, and healthcare providers.

Main Results:

• High interest from all stakeholders in using avatars and virtual agents for self-management.
• Adolescents believe virtual characters can reinforce support, fit lifestyles, and aid goal setting.
• Preferred modalities include mobile and desktop devices, with a desire for a virtual coach/teacher and a buddy avatar.

Conclusions:

• Study findings support the integration of avatars and virtual agents into adolescent chronic weight management interventions.
• A personal relationship with virtual characters can enhance engagement and long-term retention.
• This research provides a foundation for developing socio-technical chronic care models for adolescents.
