Ecological Momentary Assessment of Physical Activity: Validation Study
BACKGROUND Ecological momentary assessment (EMA) may elicit physical activity (PA) estimates that are less prone to bias than traditional self-report measures while providing context. OBJECTIVES The objective of this study was to examine the convergent validity of EMA-assessed PA compared with accelerometry. METHODS The participants self-reported their PA using International Physical Activi...
متن کاملEcological Momentary Assessment in Physical Activity Research.
Theories explaining why individuals participate in physical activity often do not take into account within-person variation or dynamic patterns of change. Time-intensive methods such as Ecological Momentary Assessment are more conducive to capturing time- and spatially-varying explanatory factors and intraindividual fluctuations than traditional methods and thus may yield new insights into the ...

متن کاملPhysical and social contextual influences on children's leisure-time physical activity: an ecological momentary assessment study.
BACKGROUND This study used real-time electronic surveys delivered through mobile phones, known as Ecological Momentary Assessment (EMA), to determine whether level and experience of leisure-time physical activity differ across children's physical and social contexts. METHODS Children (N = 121; ages 9 to 13 years; 52% male, 32% Hispanic/Latino) participated in 4 days (Fri.-Mon.) of EMA during ...
متن کاملA Mobile Ecological Momentary Assessment Tool (devilSPARC) for Nutrition and Physical Activity Behaviors in College Students: A Validation Study
BACKGROUND The majority of nutrition and physical activity assessments methods commonly used in scientific research are subject to recall and social desirability biases, which result in over- or under-reporting of behaviors. Real-time mobile-based ecological momentary assessments (mEMAs) may result in decreased measurement biases and minimize participant burden. OBJECTIVE The aim was to exami...
