Ecological momentary assessment.
Assessment in clinical psychology typically relies on global retrospective self-reports collected at research or clinic visits, which are limited by recall bias and are not well suited to address how behavior changes over time and across contexts. Ecological momentary assessment (EMA) involves repeated sampling of subjects' current behaviors and experiences in real time, in subjects' natural en...
متن کاملBagged Boosted Trees for Classification of Ecological Momentary Assessment Data
Ecological Momentary Assessment (EMA) data is organized in multiple levels (per-subject, per-day, etc.) and this particular structure should be taken into account in machine learning algorithms used in EMA like decision trees and its variants. We propose a new algorithm called BBT (standing for Bagged Boosted Trees) that is enhanced by a over/under sampling method and can provide better estimat...
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 کاملAn ecological momentary assessment of lapse occurrences in dieters.
PURPOSE The aim of this study is to investigate the factors related to dietary lapse occurrence in a community sample of dieters. METHODS An ecological momentary assessment (EMA) methodology, via mobile phone-based diaries, was employed to record dietary lapse occurrences in a group of dieters (N = 80; M age = 41.21 ± 15.60 years; M BMI = 30.78 ± 7.26) over 7 days. RESULTS Analyses indicat...
متن کاملDevelopment of an ecological momentary assessment scale for appetite
BACKGROUND An understanding of eating behaviors is an important element of health education and treatment in clinical populations. To understand the biopsychosocial profile of eating behaviors in an ecologically valid way, ecological momentary assessment (EMA) is appropriate because its use is able to overcome the recall bias in patient-reported outcomes (PROs). As appetite is a key PRO associa...
