An assessment of self-reported physical activity instruments in young people for population surveillance: Project ALPHA

The assessment of physical activity is an essential part of understanding patterns and influences of behaviour, designing interventions, and undertaking population surveillance and monitoring, but it is particularly problematic when using self-report instruments with young people. This study reviewed available self-report physical activity instruments developed for use with children and adolescents to assess their suitability and feasibility for use in population surveillance systems, particularly in Europe.

Systematic searches and review, supplemented by expert panel assessment.
