Ecological Momentary Assessment (EMA) delivered through mobile smartphones offers media psychology research a methodological breakthrough in capturing psychological responses to digital media exposure in real time, in natural contexts, and at ecological validity levels impossible in traditional laboratory or survey designs. This paper provides a comprehensive review and methodological framework for mobile EMA in digital media psychology research, covering theoretical foundations, survey design principles, compliance optimization strategies, reactive effects and demand characteristics in EMA, analytical approaches for intensive longitudinal data, and ethical considerations for passive behavioral sensing combined with active self-report. The paper synthesizes findings from 47 published mobile EMA studies in media psychology contexts, identifying consistent methodological practices, common design errors, and evidence-based recommendations. Key design parameters are reviewed including signal-contingent versus event-contingent versus interval-contingent assessment, prompt frequency optimization, burst sampling designs, and the integration of passive behavioral sensors including GPS, accelerometer, and screen state monitoring with active self-report items. Statistical methods for analyzing intensive longitudinal data including multilevel modeling, dynamic structural equation models, vector autoregression, and network analysis are reviewed with practical implementation guidance. The paper proposes the Media-EMA Quality Standard (MEQS) specifying minimum design, compliance, and reporting requirements for mobile EMA media research. Application cases including news avoidance, social media compulsive use, media-induced emotional contagion, and sleep displacement are used to illustrate the MEQS in practice.
