Understanding Goal Setting and Behavior Change Mechanics in an Older Adult Sitting Reduction Intervention.

Area of Science:

• Gerontology
• Behavioral Science
• Public Health

Background:

• Sedentary behavior (SB) is a significant health risk for older adults.
• Effective interventions are needed to reduce sitting time in this population.

Purpose of the Study:

• To evaluate intervention fidelity, participant satisfaction, and goal-setting strategies for reducing sedentary behavior in adults aged 60 and older.
• To explore the reminder strategies employed by participants to decrease sitting time.

Main Methods:

• A 6-month randomized controlled trial with a mixed-methods approach.
• Data collection included health coaching logs, fidelity monitoring, and end-of-study satisfaction questionnaires.
• Qualitative analysis of participant goals and reminder strategies, with quantitative comparison of fidelity and satisfaction between study arms.

Main Results:

• High participant satisfaction (>90%) and coach fidelity (96% SMART goal setting) were observed in both intervention and control groups.
• Intervention participants utilized personalized outward and habit-based reminder strategies for goal achievement.
• Significant variation in chosen sedentary behavior goals indicated a need for tailored approaches.

Conclusions:

• Personalized goal-setting and reminder strategies are crucial for effectively reducing sedentary behavior in older adults.
• The findings support the importance of tailored interventions for promoting behavior change in this demographic, especially those with chronic conditions.
