Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This randomized control study is designed to understand the role of a positive psychology intervention (PARK: Positive Affect Regulation sKills) in biological aging and well-being. PARK provides a series of positive emotion skills in a self-guided online format, making the program accessible and convenient.

Our main aims are:

Aim 1: To explore the effects of PARK on psychological well-being (e.g., depression, anxiety, positive affect).

Aim 2: To explore the effects of PARK on biological age as defined by DNA methylation (DNAm) GrimAge and electrocardiogram-age (ECG-age), as well as physiological well-being in adults (e.g., cardiovascular, endocrine, musculoskeletal functioning, etc.).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The skills in the Positive Psychology Intervention (PPI), PARK (e.g., gratitude, mindful awareness and nonjudgement, and self-compassion) are designed to promote positive emotion, which has been shown to provide resilience against stress. Positive emotion, independent of stress and negative emotion, has also been associated with a lower risk of mortality and better health behaviors such as likelihood of physical activity and healthy eating. This randomized control study will compare baseline well-being scores to post-online intervention at 3 months, 6 months, and 12 months post-baseline. Secondarily, measures of biological aging (DNAm GrimAge and ECG-age) and physiological functioning measures of cardiovascular, musculoskeletal, and endocrine functioning will be explored from baseline to post-intervention measures 3 and 12 months later.

Research will be based in Northwestern's Feinberg School of Medicine through the Potocsnak Human Longevity Lab and the Department of Medical Social Sciences (MSS), with all study procedures conducted in-person at the Human Longevity Lab or online. Eligibility screening, consent, and assessments will be conducted on REDCap. Consenting participants randomized to the treatment group will receive access to the online PARK platform within two weeks. The intervention consists of a positive skills course (including weekly lessons and daily skills practice) and daily emotion check-ins, hosted by BrightOutcome. The skills will be delivered over approximately 6 weeks, and individuals can participate from any device and location with internet access.

Study Groups

Positive Emotion Skills Intervention

Participants will receive the 6-week online intervention, PARK (Positive Affect Regulation sKills Course).

Group Type EXPERIMENTAL

Positive Emotion Skills Intervention

Intervention Type BEHAVIORAL

Skills include positive events, capitalizing, gratitude, mindfulness, positive reappraisal, personal strengths, achievable goals, and self-compassion. The skills will be delivered over approximately 6 weeks, and individuals can participate from any device and location with internet access. A week will consist of 1-2 days of didactic material and 5-6 days of real-life skills practice and reporting. Participants cannot skip ahead and can only progress to the next lesson if they have completed the current one, but they can return to old lessons or exercises if they wish to.

Waitlist Control

The waitlist control condition will receive usual care in the Human Longevity Lab, which consists of a feedback report on biological age and lifestyle counseling from a clinical provider at the end of the study period. Control condition participants will have the option to gain access to the PARK platform and learn positive emotion skills after their study participation is completed at the end of 12 months.
