Core Outcome Measures in Effectiveness Trials

Developing a core outcomes set for evaluation of physical activity interventions in primary schools

General Information

Summary:
Regular physical activity is thought to have many benefits and is associated with a reduction in several health problems including obesity. Hence, current guidelines from the World Health Organization recommend 150 minutes of moderate-intensity physical activity spread throughout the week for adults and 60 minutes of moderate- to vigorous-physical activity every day for children, however few people are meeting these targets. Since children spend much of their day at school, school-based physical activity interventions could be an ideal way to increase their activity levels. However, the reported benefits differ greatly among interventions and are not necessarily comparable across studies or across interventions due to different outcomes studied. Therefore, there is a need to develop a core-outcomes set for the evaluation of school-based physical activity interventions. We will conduct a modified Delphi study to identify core outcomes of school-based physical activity interventions, by: 1) reviewing the literature to identify a list of relevant outcomes, 2) surveying relevant stakeholders on the importance of each possible outcome, 3) consulting with stakeholders during a face-to-face meeting, and incorporating stakeholder perspectives to reach consensus on a final core outcomes set.

Method(s)

Consensus meeting
Delphi process
Literature review

We will conduct a modified Delphi study to identify the core outcomes of school-based physical activity interventions. We will identify potential outcomes through a comprehensive review of the literature, and then incorporate these into a Delphi survey consisting of two rounds. A variety of stakeholders (researchers, policy makers, teachers, head teachers, governors and parents) will be asked to participate in the Delphi survey, and then invited to attend a consensus meeting to achieve consensus on a final core outcomes set.
