Emotion regulation (ER) is a key transdiagnostic process and treatment target, with particular relevance to distress disorders (depression, generalized anxiety disorder). Distress disorders, which are characterized by heightened negative emotions, are prevalent conditions with considerable public health burden and comparatively lower response to treatment. The efficacy of interventions for distress disorders may be improved by investigating components of effective ER, both as instructed in the lab (ER capacity) and as measured naturalistically in daily life (ER tendency). Effective ER is based on key components such as accurate perceptions of one's emotions (i.e., emotional awareness) as well sensitivity to the environmental context (i.e., contextual sensitivity), which facilitate the selection and implementation of the appropriate ER strategy. For individuals with distress disorders, elevated levels of perseverative negative thinking (PNT) interferes with these processes, contributing to ER deficits and increased symptoms. This contextualized and integrative model of ER in distress disorders has not been tested, and very little is known about the predictors or outcomes of effective ER tendency?a critical gap given that ER capacity is irrelevant if ER is not employed skillfully in daily life. Furthermore, examinations of ER tendency can show how individuals, considering their particular characteristics and abilities, can optimally match particular ER strategies to the specific situations they encounter. The goal of this application is to evaluate components of ineffective ER? both in the lab and in daily life? that influence the severity and course of distress disorders and functioning. Consistent with NIMH strategic objectives and the RDoC framework, this project incorporates multimodal assessment, dimensional symptom measurement, and machine learning approaches. The proposed study will be comprised of 300 adults, oversampled for elevated PNT (50%). Participants will complete a lab assessment to measure predictors of ER capacity, followed by a 10- day ecological momentary assessment study examining predictors of ER tendency in daily life. To better capture negative emotions as they occur, reports in daily life will be physiologically-triggered with algorithms that detect potential episodes of psychological stress. Effective ER will be operationalized in multiple ways in the lab and in daily life, using self-reported changes in affect, physiological indices, and perceived ER success. Effective ER capacity and tendency will then be examined as predictors of distress symptom, functioning, and well-being trajectories assessed monthly for 12 months. Additionally, an exploratory aim is to create predictive models from a multifaceted battery of theoretically motivated variables that impact ER tendency and subsequent clinical outcomes. To this end, machine learning will be used to build a clinically-relevant framework for how person- level, situation-level, and ER strategy use interact to predict optimal ER. Overall, this project contributes to the long-term goal of identifying and refining targets for personalized interventions, by more precisely isolating key mechanisms of effective ER for specific individuals and the contexts they encounter in their daily lives.
The proposed study seeks to examine predictors (i.e., emotional awareness, contextual sensitivity, perseverative negative thinking) of dysfunctional emotion regulation that contribute to depression and anxiety, as well as to provide an initial framework for optimal emotion regulation in individualized daily life contexts. This study uses multiple measurements (behavioral, psychophysiological, self-report, clinical interview) in the laboratory and in naturalistic settings in daily life, and it focuses on dimensional and transdiagnostic features that underlie multiple disorders. Consistent with NIMH's mission, findings will be relevant to public health because they can help refine intervention targets and inform personalized treatment for depression and anxiety, which are common and impairing conditions.
