Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

While people commonly understand that regular physical exercise conveys many health benefits, only 20% of U.S. adults take regular exercise and they have difficulty maintaining new healthy behaviors. The goal of this study is to use a planning intervention to help establish and maintain a daily step regimen in working midlife adults. The investigators will ask participants to plan when, where, and how to act on a daily walking goal in conjunction with a scheduling intervention to increase the chances that they will maintain this new regimen. The effectiveness of three different scheduling interventions will be compared.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

While people commonly understand that regular physical exercise conveys many health benefits, only 20% of U.S. adults take regular exercise and they have difficulty maintaining new healthy behaviors. The goal of this study is to use a planning intervention to help establish and maintain a daily step regimen in working midlife adults. The investigators will ask participants to plan when, where, and how to act on a daily walking goal in conjunction with a scheduling intervention to increase the chances that they will maintain this new regimen. Participants will be randomly assigned to one of three conditions: consistent schedule, inconsistent schedule, no schedule. All participants will be provided with an accelerometer to measure their daily activity and as a behavioral support for our intervention and they will be given a step goal. The goal given to each individual will be to increase immediately their daily steps to a level based on recommended guidelines (e.g., Hill, Wyatt, Reed, and Peters, 2003). The investigators will test which version of the scheduling intervention is most successful for increasing and maintaining step counts. It is predicted that participants in the consistent schedule condition will increase their step count more than those participants in the no schedule control condition, and that they will maintain this activity for a longer period after the intervention period is complete than those participants in the inconsistent schedule condition.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Participants will be randomly assigned to one of three between-subjects conditions: consistent schedule, inconsistent schedule, no schedule. The study is a longitudinal study over 9 weeks, including a baseline week, a 4-week intervention and a follow-up assessment 4 weeks after the intervention.

Primary Study Purpose

SUPPORTIVE_CARE

Blinding Strategy

SINGLE

Participants

Participants are not aware of whether they are in an experimental or control condition.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

No schedule control

This group will receive an accelerometer and daily step goal. They will monitor their steps over the 9 week duration of the study. They will also monitor their steps over the 9 week duration of the study. They will have the same level of contact as the other two conditions.

Group Type ACTIVE_COMPARATOR

Accelerometer

Intervention Type DEVICE

Participants use an accelerometer to monitor their steps activity

Step goal

Intervention Type BEHAVIORAL

Participants are given a daily step goal to aim for

Consistent schedule condition

This group will receive an accelerometer and daily step goal. They will monitor their steps over the 9 week duration of the study. They will have the same level of contact as the other two conditions. In addition they will plan when, where, and how they will take steps in consistent contexts, i.e., that are very similar from day to day.
