“…By using repeated assessments in a person’s natural environment and in real time, EMA aims to “capture life as it is lived” (Bolger, Davis, & Rafaeli, 2003). It has been successfully used to investigate psychosis, substance use, mood disorders, panic disorder, and specific phobias and to monitor treatment processes as documented, for example, in Stone, Shiffman, Atienza, and Nebeling (2007) and the special sections and issues of the Journal of Personality (Tennen, Affleck, & Armeli, 2005), Psychological Assessment (Trull & Ebner-Priemer, 2009), European Psychologist (Ebner-Priemer, Kubiak, & Pawlik, 2009), and European Journal of Psychological Assessment (Westmeyer, 2007). Thanks to EMA, considerable advances have been made in the study of phenomenology, etiology, psychological models, biological mechanisms, treatment, and gene-environment interactions in psychopathology (Ebner-Priemer & Trull, 2009; Myin-Germeys et al, 2009, for reviews).…”
