Behavior Change Techniques (BCTs) to Improve Low Intensity Physical Activity in Older Adults

"Four behavioral changes techniques (BCTs) will be administered to participants in random order. The BCTs are defined as follows:~1. Goal setting: set or agree on a goal defined in terms of behavior to be achieved. Example: Set the goal of walking 2,000 steps more per day.~2. Action planning: prompt detailed planning of performance of behavior (must include a setting \[walking to the mailbox\], frequency, duration, and intensity. Example: Develop a plan to walk today.~3. Self-Monitoring of behavior: establish a method for person to monitor and record their number of steps based on their Fitbit. Example: Did you check your Fitbit and record daily total number of steps?~4. Feedback on behavior: Monitor and provide informative or evaluative feedback on performance of the behavior (e.g. form, frequency, duration, intensity). Example: You walked 6,000 steps today. This is 1,000 steps above your baseline."
