Using Mobile-Technology-Based Ecological Momentary Assessment (EMA) Methods With Youth: A Systematic Review and Recommendations.

Ecological momentary assessment (EMA) methods are increasingly used in social and health sciences, but the feasibility and best practices for using EMA with youth are not yet clear. We conducted a systematic review of studies that used self-report EMA methods with youth; the goal was to identify common approaches and challenges to implementation and develop recommendations for future research. We examined 54 peer-reviewed papers that reported on 24 unique studies. Papers were evaluated using a standardized, three-dimensional coding scheme focused on the following: (1) sample characteristics; (2) EMA data collection methods (sampling duration, frequency, hardware/software); (3) study implementation methods (technical/logistical challenges, training participants, compliance). Overall, the research suggests EMA can be successfully implemented with youth (age ∼ ≥7) from diverse backgrounds, but protocol adaptations may be necessary for younger children. Study design and implementation challenges and recommendations for research on youth are provided.
