About this trial
This pilot study will develop and evaluate ViaHabit, a personalized walking intervention designed to promote physical activity habit formation among sedentary midlife adults (ages 45-65). During an initial 2-week observation period, participants' daily routines will be characterized using data collected from wearable devices, smartphones, and digital calendars. Personalized models will identify routine transitions, defined as periods between everyday activities, that may serve as receptive opportunities for initiating physical activity. Participants will then complete a 4-week intervention in which they create individualized "if-then" action plans linking routine transitions to a 15-minute brisk walk and receive automated smartwatch prompts at selected cue times. The study will assess the feasibility and acceptability of identifying routine transitions and delivering timely physical activity prompts, while exploring changes in walking behavior, habit strength, and physical activity engagement.

ViaHabit
BehavioralViaHabit is a personalized, cue-based walking intervention designed to promote physical activity habit formation in sedentary midlife adults. Following a 2-week observation period, individualized routine models are developed using data collected from wearable devices, smartphones, and digital calendars. Participants then complete a coaching session to identify up to two routine transitions that can serve as cues for physical activity and develop personalized if-then action plans linking each cue to a 15-minute brisk walk. During the 4-week intervention period, automated smartwatch notifications are delivered at the selected routine-transition cues to increase cue salience and support initiation of walking behavior. The intervention aims to strengthen cue-behavior associations through repeated pairing of routine completion cues with walking, thereby increasing behavioral automaticity and physical activity participation.

Trial outcomes
Primary outcomes
1
Feasibliity of the ViaHabit Intervention - Recruitment
Feasibility will be assessed by participant recruitment rates.
Time frame
Week 8 (end of intervention)2
Feasibliity of the ViaHabit Intervention - Retention
Feasibility will be assessed by participant retention rates.
Time frame
Week 8 (end of intervention)3
Feasibliity of the ViaHabit Intervention - Data Collection
Feasibility will be assessed by participant completion of Phase 1 data collection.
Time frame
Week 8 (end of intervention)Secondary outcomes
1
Habit Strength for Walking
Habit strength will be assessed using the 4-item Self-Reported Behavioral Automaticity Index (SRBAI), adapted to each participant's selected routine-transition cue. Higher scores indicate greater automaticity of walking behavior in response to the cue.
