Trial Outcomes & Findings for Behavior Change Techniques (BCTs) to Improve Low Intensity Physical Activity in Older Adults (NCT NCT04967313)
NCT ID: NCT04967313
Last Updated: 2023-02-01
Results Overview
Participant steps will be assessed continuously using a Fitbit mobile device. Daily steps for participants will be aggregated by baseline and intervention phases to generate average daily steps in each phase. Changes in daily steps between baseline and intervention phases will be compared using Generalized Linear Mixed Model analyses. Changes in daily steps between intervention and baseline will be represented using a regression parameter.
COMPLETED
PHASE1
60 participants
Steps will be assessed continuously via worn activity tracker. Step counts will be aggregated and analyzed at the daily level. This will yield 70 daily measurements of physical activity over the course of the 10-week study.

Participant Flow
Participants were consented and entered a 2-week baseline period prior to beginning the intervention. Participants who were not compliant with trial requirements during baseline did not continue to receive the intervention. Data were collected for the overall BCT intervention and not for each individual BCT.

Behavioral Change Techniques to Increase Walking
Individuals will receive daily text messages with the goal of increasing daily walking by 2,000 more steps five days per week. Participants will be enrolled for a baseline period lasting two weeks where their average daily activity level will be assessed using a Fitbit device to generate an average daily step counts. Following completion of baseline, participants will receive daily text messages of behavior change techniques (BCTs) for eight weeks. The four BCTs utilized in this study are: goal setting, action planning, self-monitoring of behavior, and feedback on behavior. Each BCT will be delivered to participants daily for a two-week block. Four blocks (one BCT per block) will be delivered to the participant. The order in which the BCT interventions are presented to participants will be randomized by the study statistician. The goal of the BCT text messages will be to encourage walking behavior.
Behavioral Change Techniques: Four behavioral changes techniques (BCTs) will be administered to participants in random order.

PRIMARY outcome
Timeframe: Steps will be assessed continuously via worn activity tracker. Step counts will be aggregated and analyzed at the daily level. This will yield 70 daily measurements of physical activity over the course of the 10-week study.Population: GLMM Regression for Change in Daily Steps Due to BCT Intervention
Participant steps will be assessed continuously using a Fitbit mobile device. Daily steps for participants will be aggregated by baseline and intervention phases to generate average daily steps in each phase. Changes in daily steps between baseline and intervention phases will be compared using Generalized Linear Mixed Model analyses. Changes in daily steps between intervention and baseline will be represented using a regression parameter.

PRIMARY outcome
Timeframe: Assessed once after completion of the study at 10 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.

SECONDARY outcome
Timeframe: Assessed at baseline, week 2, week 4, week 6, week 8, and week 10.This will be assessed using the Self-Efficacy for Walking (SE-W) scale,\[1\] an 10-item measure assessing patient's capabilities to walk for durations of 5 to 50 minutes. Items are scored from 0 to 100%, with scores of 0% indicating participants are "not at all confident" they could walk for that duration and scores of 100% indicating the participants are "highly confident" they could walk that duration. Items are average to create a total score, with higher scores indicating higher levels of beliefs about capabilities/self-efficacy.

SECONDARY outcome
Timeframe: Assessed once after completion of the study at 10 weeks.Participants will be asked via survey about their attitudes and opinions regarding the personalized trial implementation (e.g., Did the trial feel burdensome?). Participants will rate items on a 7-point Likert scale with responses ranging from "0 - Strongly Disagree" to "6 - Strongly Agree". Higher scores indicate greater levels of agreement. Scores on each item will be reported with means and standard deviations.
