简要总结
The goal of this clinical trial is to evaluate whether different approaches to action planning can promote physical activity (PA) habits, increase PA behavior, and improve cognitive functioning in older adults who are currently inactive or insufficiently active.
The main questions it aims to answer are:
- Does a trial-and-error approach to PA action planning lead to greater improvements in PA habits, PA behavior, and cognitive functioning compared to standard PA planning or non-PA planning?
- Does greater consistency and successful enactment of action plans result in more substantial changes in PA habits, behavior, and cognitive functioning?
Researchers will compare three groups to determine which planning approach yields superior outcomes.:
- Non-PA planning (generic weekly planning)
- PA planning (weekly planning for PA)
- PA trial-and-error planning (weekly PA plans followed by preferred plan adoption)
Participants will:
- Wear Fitbit monitors continuously for 9 months to track PA behavior
- Complete mobile cognitive assessments daily for 7 days before the intervention, monthly during the intervention, and at follow-up
- Create action plans and report on PA habits, intentions, and plan enactment weekly during the intervention and at follow-up

研究组 & 干预措施
Physical activity trial and error planning group
Participants in this group will be instructed to create weekly action plans to engage in physical activity. Participants in this condition will be advised to spend 6 weeks trying different action plans each week to see what works best for them and then sticking to their preferred plan for the remaining weeks so their brain can 'learn' these mental cue-behavior associations that underpin habits. Further, participants in this group will be informed of the recommended volume of physical activity based on federal guidelines and instructed to develop action plans to engage in a self-selected physical activity (consistent with low-to-moderate intensity physical activity) that progressively increase in intensity and duration during the 6-month intervention. Participants in this group will receive weekly prompts and reminders to create action plans on their smartphone.

Physical activity planning group
Participants in this group will be instructed to create weekly action plans to engage in physical activity. Further, participants in this group will be informed of the recommended volume of physical activity based on federal guidelines and instructed to develop action plans to engage in a self-selected physical activity (consistent with low-to-moderate intensity physical activity) that progressively increase in intensity and duration during the 6-month intervention. Participants in this group will receive weekly prompts and reminders to create action plans on their smartphone.
干预措施: PA Action Planning (Behavioral)
Non-physical activity planning group
The non-physical activity planning group is our control condition, accounting for social contact and attention. Participants in this group will be instructed to create weekly action plans for one of four target health behavior (i.e., practice good sleep hygiene, make healthy food choices, wash my hands, practice good oral hygiene). Participants in this group will receive weekly prompts and reminders to create action plans on their smartphone.

结局指标
主要结局
Change in Device-Based Physical Activity from Baseline to 6 Months
时间窗: Device-based physical activity will be assessed daily during the 7-day baseline, daily during the 6-month intervention, and daily during the 3-month follow-up period.
The wrist-worn Fitbit Inspire will provide an device-based measure of minutes/day of moderate-to-vigorous physical activity (based on step cadence)
次要结局
- Change in Grid Memory Task Performance from Baseline to 6 Months(The Grid Memory Task will be administered for 7 consecutive days at baseline, for 7 days each month during the 6 month intervention, and for 7 days at the end of the 3-month follow-up.)
- Change in Symbol Search Task Performance from Baseline to 6 Months(The Search Symbol Task will be administered for 7 consecutive days at baseline, for 7 days each month during the 6 month intervention, and for 7 days at the end of the 3-month follow-up.)
- Change in Physical Activity Habit Strength from Baseline to 6 Months(The single item will be administered baseline, weekly during the 6-month intervention, and at the end of the 3-month follow-up.)
