Area of Science:

• Gerontology
• Behavioral Science
• Health Technology

Background:

• Community-dwelling older adults often face challenges in maintaining physical activity.
• Motivational Interviewing (MI) is an effective behavior change technique.
• Virtual delivery methods offer potential for wider reach and accessibility.

Purpose of the Study:

• To assess the feasibility and acceptability of Virtual Motivational Interviewing (VIMINT) for enhancing physical activity in older adults.
• To explore participant and counselor experiences with VIMINT.
• To inform future effectiveness trials of VIMINT.

Main Methods:

• A mixed-method, single-group pre- and post-design feasibility study.
• Five VIMINT sessions delivered via Zoom to community-dwelling older adults.
• Feasibility assessed via recruitment, retention, adherence, and satisfaction; acceptability via qualitative interviews; physical activity measured at baseline, post-intervention, and follow-up.

Main Results:

• High retention rate (88%) and session attendance (92.5%).
• Participants reported high satisfaction (24.14/32).
• Qualitative analysis revealed positive impacts and suggestions for improvement, indicating feasibility and acceptability.

Conclusions:

• Virtual Motivational Interviewing (VIMINT) is a feasible and acceptable intervention for increasing physical activity in community-dwelling older adults.
• The study provides a foundation for larger trials on VIMINT effectiveness.
• VIMINT demonstrates potential as a scalable solution for promoting healthy aging.
