Mood and Thought Process Study

Summary

The primary objective for this project is to test whether affective executive functioning is a mechanism of action of mindfulness-based cognitive therapy and Wellness for Wellbeing. The main questions it aims to answer are: 1. Test the effect of MBCT vs. Wellness for Wellbeing on affective inhibition (i.e., emotionally valenced inhibition as measured via the affective Go/No Go task) using an RCT. 2. Test the effect of MBCT vs. Wellness for Wellbeing on (a) affective updating and (b) affective shifting. Outcomes will be measured with the affective n-Back and the affective Internal Switching Task, respectively. 3a) The investigators will examine whether depression symptom severity co-varies with change in affective executive functioning (i.e., affecting inhibition, shifting, and updating) over time. 3b) The investigators will examine whether compliance with treatment protocol (e.g., number of classes attended, amount of home practice) predicts endpoint executive functioning. Participants will complete surveys, interviews, and computer tasks, and will be randomized to either Mindfulness-Based Cognitive Therapy or Wellness for Wellbeing.
