Overview
Brief Summary
This personalized trial will evaluate the effects of five behavioral change techniques (BCTs) described in Habit Formation Theory (Goal setting, Action Planning, Self-Monitoring, Behavioral Practice/Rehearsal and Habit Formation) delivered by text message to enhance low-intensity walking by 2,000 more steps per day/5 days per week in healthy Northwell employees aged 45-75 years old.
Detailed Description
This pilot study uses a virtual, single-arm, personalized design to evaluate the effects of the five behavioral change techniques (BCTs) described in Habit Formation Theory (Goal Setting, Action Planning, Self-Monitoring, Behavioral Practice/Rehearsal and Habit Formation) delivered by text message to enhance low-intensity walking by 2,000 more steps per day/5 days per week in healthy Northwell employees aged 45-75 years old. Up to sixty participants will complete a 12-week personalized trial of their walking behavior and assess all five behavioral change techniques described in habit formation theory. Prior to beginning the trial, participants will be sent a Fitbit® activity tracking watch that monitors number of steps per day. Participants will be instructed to wear the Fitbit device all day and night, even when they are sleeping. The single-arm, personalized trial will be comprised of a 2-week baseline/screening phase and a 10-week intervention phase. During the baseline phase, participant's baseline levels of physical activity (operationalized as average steps per day measured using the Fitbit device) and adherence to the trial protocol (operationalized as wearing the Fitbit device for a minimum of 10 hours per day and completing daily survey measure) will be assessed. Participants who are adherent to the study protocol, defined as adherence to Fitbit use and survey measures on 80% or more days during baseline, will proceed to the intervention phase. At the beginning of the intervention, participants will develop a walking plan with the goal of walking 2,000 more steps per day than their average levels of baseline activity (e.g., if you walked an average of 6,000 steps per day during baseline, the new goal would be 8,000). The walking plan will include details about the day, time, and location of walking behavior. Participants will commit to walking according to this plan 5 days per week (e.g., walking 8,000 steps per day on 5 planned days. A time-sensitive text of all 5 BCTs will delivered to the participant when the context (e.g., day of week, time of day) that they pre-selected is encountered. Participants will later receive a text message with a link to a secure survey in which they will note whether they engaged with the five behavioral change techniques which were prompted. The goal of the intervention is to help participants make their walking behavior habitual and automatic. Participants will be assessed in terms of their satisfaction with the personalized trial design, their Fitbit-measured daily steps, adherence to their walking plan, and the automaticity of their walking behavior. After completion of the intervention phase, participants will be allowed to keep the Fitbit device.

Outcomes
Primary Outcomes
Participant Satisfaction With Personalized Trial Components.
Time Frame: Assessed once after completion of the study at 12 weeks.
Participants will rate their satisfaction with the Personalized Trial overall and with individual elements of the trial in a satisfaction survey developed for this trial. Participants will rate 9 items assessing satisfaction with methods and process of the trial on a 4-point Likert scale with responses ranging from "0 - Not at all satisfied" to "3 - Very satisfied". Higher scores indicate greater levels of satisfaction. Means and standard deviations will be reported for each element of satisfaction.
Change in Automaticity Score.
Time Frame: Assessed daily via online survey for participants across the duration of the 10-week intervention. Daily assessments will be aggregated by week to generate weekly means for automaticity.
Automaticity of behavior is assessed by a 4-item questionnaire asking about the automaticity of participant's walking behavior using a 4-point Likert scale with responses ranging from "Strongly Disagree" to "Strongly Agree". Items are summed together to form a total score ranging from 0 to 12, with higher scores indicating that participant's new walking behaviors have become more habitual and automatic. Change in daily automaticity levels over the course of the intervention period will be examined until scores level out and reach a score of 8 or more on 7 consecutive days. Participants will be judged to have reached an asymptote at this point in time. The proportion of the sample that has achieved automaticity will be reported as a number with percentage \[N(%)\]. Time-to-event analyses will be conducting examining participant differences in reaching an asymptote for automaticity and overall time-to-event will represented using Kaplan-Meier curves.
Secondary Outcomes
- Within-person Change in Daily Steps.(Steps will be assessed continuously via worn activity tracker and step counts will be reported daily.)
- Participant Attitudes and Opinions Towards Personalized Trials.(Assessed once after the completion of the intervention period.)
- Participant Adherence to Self-Monitoring.(Assessed daily via online survey for participants across the duration of the 10 week intervention. Daily responses will be aggregated across the intervention to determine an overall proportion of days adherent self-monitoring of behavior.)
- Proportion of Days Adhering to Walking Habit.(Assessed once after completion of the study at 12 weeks.)
