Physical and Social Environmental Influence on Children's Exercise: Preparation (Pre-PLACE) (Pre-PLACE)
September 27, 2022 updated by: Stephanie Broyles, Pennington Biomedical Research Center
Community based interventions are more acceptable to community members when all participants receive the intervention.
A 'stepped-wedge' or 'multiple-baseline' design allows for all participants to receive the intervention by randomizing participants into conditions defined by the length of the baseline period.
The primary aim of this pilot study is to gather data that will allow the researchers to estimate parameters, such as the appropriate length of the baseline period that will allow them to power a larger study.
A second key aim is to determine if a smartphone intervention that is delivered to parents can increase physical activity in their 6-10 year old inactive children.
Study Overview
Detailed Description
Low levels of physical activity in childhood are related to obesity and risk for diabetes and cardiovascular disease.
This translational study is an attempt to take interventions that have been shown to be effective in highly controlled setting and implement them in the community.
We will utilize a form of a single case design (i.e., stepped-wedge or multiple-baseline design), which is an underused, though promising, alternative to the traditional, parallel-group randomized trial in which each study participant acts as his/her own control.
Participants will be randomized to baseline periods of varying length such that the change in the study outcome can be causally attributed to introduction of the intervention.
In accordance, families will be randomized to a 2, 4, or 6-week baseline period before being administered the P-Mobile app based intervention.
All families will receive the same P-Mobile intervention following the baseline period.
The P-Mobile intervention will be delivered to parents via the P-Mobile smartphone app; it consists of 10 lessons designed to increase physical activity in children.
The parents will also receive notifications designed to prompt physical activity, motivate, and remind parents of lesson content.
The intervention will also utilize an adaptive step goal approach, in which the step goal is modified based on each participant's individual performance.
The primary aims of the study are: (1) To estimate several parameters, which will allow us to redesign our study as a single case design (and to conduct simulation-based power calculations): (a) average day-to-day variability in daily steps during the baseline period, (b) average autocorrelation in the daily step data, and (c) average effect size at 2 weeks, 4 weeks, and 6 weeks after introduction of the intervention.
(2) To test the feasibility of the P-Mobile app (3) To demonstrate our ability to recruit participants from targeted neighborhoods.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: 2-Week Baseline
Families will be randomized to a 2-week baseline period before being administered the P-Mobile app based intervention.
All families will receive the same P-Mobile intervention following the baseline period.
The intervention will consist of 10 lessons delivered over 12 weeks designed to increase physical activity in children.
The lessons will be delivered weekly and are the same ones utilized in the P-Mobile pilot study.
The parents will also receive notifications designed to prompt physical activity, motivate, and remind parents of lesson content.
|
The behavioral strategies are based on Social Cognitive Theory.
The following topics will be covered: self-monitoring, goal setting, stimulus control, making time for exercise, exercising in- and outdoors, problem-solving, reinforcing PA, reducing sedentary behaviors, relapse prevention, parental modeling, lifestyle exercise, self-efficacy, self-management, parental PA modeling, parental co-participation, and establishing PA rules.
Parents will be provided with adapted step goals (based on principles of shaping).
Text messages will be designed to prompt PA, remind parents of concepts from the lessons, and motivate behavioral change.
|
Active Comparator: 4-Week Baseline
Families will be randomized to a 4-week baseline period before being administered the P-Mobile app based intervention.
All families will receive the same P-Mobile intervention following the baseline period.
The intervention will consist of 10 lessons delivered over 12 weeks designed to increase physical activity in children.
The lessons will be delivered weekly and are the same ones utilized in the P-Mobile pilot study.
The parents will also receive notifications designed to prompt physical activity, motivate, and remind parents of lesson content.

Active Comparator: 6-Week Baseline
Families will be randomized to a 6-week baseline period before being administered the P-Mobile app based intervention.
All families will receive the same P-Mobile intervention following the baseline period.
The intervention will consist of 10 lessons delivered over 12 weeks designed to increase physical activity in children.
The lessons will be delivered weekly and are the same ones utilized in the P-Mobile pilot study.
