Emotion Regulation Training to Reduce Cardiovascular Disease Risk Among Depressed Young Adults in Southern Mississippi

The proposed study will investigate the utility of a single-session emotion regulation training to reduce CVD risk among young adults diagnosed with MDD living in Southern MS. Using an single-arm, non-randomized design, young adults aged 18-29 will undergo a single-session emotion regulation skills training. Before and immediately after the skills training session, participants will supply several biological metrics tied to CVD risk: resting HRV, inflammation (measured via c-reactive protein \[CRP\]), and blood pressure. Participants will provide the same biological metrics at a one-week follow-up visit to assess short-term sustained gains following the single-session intervention and complete a 7-day ecological momentary assessment (EMA) of their daily emotion regulation skills use and depressive symptoms between these two visits.
