An interventional study of Out of School Time Coach (OST-Coach) in Physical Activity, sponsored by Kansas State University. Recruiting at 1 site in United States. Open to participants aged 5 Years to 11 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-09-26.
Sponsored by Kansas State University · Not applicable, Interventional, and Basic science
The goal of this study is to determine whether a data coaching process called Out of School Time Coach (OST-Coach) can increase child physical activity (PA) behavior, perceived motor competence, and staff PA-promoting practices.
Aim 1: Determine the impact that the OST-Coach intervention has on child PA behavior and perceived motor competence. The investigators hypothesize that integrating a targeted data coaching system will increase the amount of PA children engage in during the OST program and enhance their perceived motor competence compared to sites receiving standard practice.
Aim 2: Assess the impact of the OST-Coach intervention on staff PA-promoting practices. The investigators will measure the effectiveness of the OST-Coach intervention by observing staff behavior and assessing their willingness to integrate evidence-based practices during OST programming. It is hypothesized that OST leaders at intervention sites will implement more PA-promoting practices.
Child physical activity will be measured via systematic observation and a survey assessing perceived motor competence. Staff PA-promoting behaviors will be observed via systematic observation and evaluated through a survey to understand the impact of the data coaching process. The intervention is delivered at the staff level, with feedback provided four times throughout the academic year.
Exclusion Criteria:
Intervention arm (OST-Coach) will receive four data coaching sessions on the data collected at intervention sites. Data will be compiled into a data report and then shared back to the site leaders. Data coaching sessions will follow IDPR principles, first session (investigate), second session (design), third session (practice) and fourth session reflect).
Behavioral: Out of School Time Coach (OST-Coach)
Sites will not receive OST-Coach intervention but will receive data reports.
Four data coaching session (investigate, design, practice, reflect) will be conducted over an academic year. Each session will involve: a customized site level data report, goal setting and implementing strategies to address child physical activity, motor competence, and staff physical activity promoting behaviors.
Child Physical Activity
To ensure broader dissemination of this work and make it more feasible for OST-related programs to capture PA data, the investigators will measure child PA through systematic observation. Specifically, they will use the System for Observing Play and Leisure Activity in Youth (SOPLAY), a momentary time sampling technique that systematically observes child PA behavior. During a SOPLAY scan, each child in the activity setting is coded as sedentary, walking, or very active. Additional scans can be conducted for females and males to account for potential group-level gender differences. The validity of SOPLAY has been established through heart rate monitoring and accelerometry-based activity monitors.
Time frame: Through study completion, 1 year.
Staff Physical Activity Promoting Behavior
A modified version of the System for Observing Staff Promoting Physical Activity and Nutrition (SOPSAN) will be used to capture site leader evidence-based PA promoting practices during OST programming. Scans will begin as soon as children enter the OST site and will last during the duration of designated PA related programming. Target areas will be identified within the OST setting before scans begin and five completed scans will be conducted per target area before moving on to scan another identified area.
Time frame: Through study completion, 1 year
Child Percieved Motor Competence
PlaySelf survey will be implemented at baseline and after the completion of 3 data coaching sessions.
Time frame: Baseline and end of 1 year
Plan to share: Yes — De-identified individual participant data that underlie the results reported in the study, including baseline characteristics, and outcome measures, will be shared. Supporting documents such as the study protocol and statistical analysis plan will also be available. Data will be accessible beginning 12 months after publication for researchers who provide a methodologically sound proposal.
