Type: dissertation
Abstract: Recently, researchers have been using new methodologies to overcome the weaknesses inherent in retrospective self-reports.One such method, Ecological Momentary Assessment (EMA), stresses the continuous investigation of individual differences in behavior, cognition, and affect in the natural environment (Shiffman & Stone, 1998).Stone & Shiffman (1994) outline four qualities that define EMA.First, EMA assesses phenomena at the moment they occur in order to reduce recall biases.Second, EMA is dependent upon careful timing of assessments in order to ensure that an unbiased sample of the target behavior is assessed.Third, EMA methods typically obtain a significant number of repeated observations in order to produce more reliable samples and allow researchers to delineate covarying relationships over time.Finally, EMA measurements are made in the environment that participants typically inhabit.These characteristics of EMA are essential for researchers interested in understanding dynamic processes as they evolve over time (e.g., Marlatt, 1985;
