Research question

“Can 2-week ambulatory data on physical activity and on negative and positive affect discriminate persons with different psychiatric status (yes versus not having a depressive and/or anxiety disorder)?”

Abstract

This study is using data from the NESDA cohort to explore the temporal associations between actigraphy-assessed physical activity and EMA-assessed positive and negative affect in a sample comprised of individuals with depressive and/or anxiety disorders diagnosis, subthreshold depressive and/or anxiety symptoms, and asymptomatic individuals. The first aim is to examine how these associations differ between persons with current disorders, subthreshold disorders and asymptomatic individuals, using a confirmatory subgroup approach. The secondary aim is to identify data-driven subgroups based on similar patterns of within-person associations over time. Data-driven subgroups are compared to the confirmatory subgroups and each another regarding patient, sociodemographic, psychiatric clinical and daily characteristics.
