简要总结
This 12-week trial will test the efficacy of a personalized, multi-component, personalized text-message delivered behavior change technique (BCT) intervention to encourage habitual hourly physical activity among care providers of persons with Alzheimer's Disease and Alzheimer's Disease Related Dementias (AD/ADRD) via the key mechanism of behavior change (MoBC) of automaticity.
The main question it aims to answer is whether a multi-component, personalized BCT intervention to increase habitual walking of >250 steps/hour will lead to successful development of habitual hourly walking among 50% of caregivers.

研究组 & 干预措施
Behavior Change Technique Package
This will be a 12-week, single-arm, multi-component, personalized BCT intervention. Participants will be provided with 4 BCTs daily (Goal Setting, Action Planning, Self-Monitoring, and Prompt/Cue) that have been associated with habit formation theory and development of physical activity habits in prior research.
干预措施: Behavior Change Technique Package (Behavioral)
结局指标
主要结局
Binary indicator of habit formation
时间窗: Baseline to intervention period (12 weeks)
The primary outcome will be a binary indicator of habit formation. A null hypothesis rate of 30 percent will be used. There will be a comparison of the achieved proportion of habitual walking versus this null level, using a 1-sample binomial test with a 2-sided alpha at 5 percent. For the purposes of this current analysis, it is assumed that 50 percent of the sample will achieve habitual hourly walking following the BCT intervention to encourage habit formation. Rate of habit formation will be summarized using the observed proportion along with a 95 percent confidence interval.
次要结局
- Habit formation association with changes in automaticity(Baseline (first 2 weeks of study) and last 2 weeks of intervention)
- Longitudinal association between automaticity and habitual walking over time(Baseline to intervention period (12 weeks))
- Heterogeneity of treatment effects for habit formation and on changes in automaticity(Baseline to intervention period (12 weeks))
