About this study
Official title: Emotional Well-being and Biomarkers of Healthy Aging
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.).
Read the detailed description
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Positive Emotion Skills InterventionBehavioural
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.
| Study group | Role | What they receive |
|---|---|---|
| Positive Emotion Skills Intervention | Experimental | Participants will receive the 6-week online intervention, PARK (Positive Affect Regulation sKills Course). Receives: Behavioral: Positive Emotion Skills Intervention |
| Waitlist Control | No intervention | 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. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Patient-Reported Outcomes Measurement Information System (PROMIS) Positive Affect (v1.0) and PROMIS Meaning and Purpose (v1.0)
Computer Adaptive Testing measure of positive emotion and purpose. Higher scores mean a better outcome (i.e., more positive emotion). Scores can range from 9-85, and a t-score of 50 represents the mean score for the United States general population with a standard deviation of 10.
Measured: Baseline, 3 months, 6 months, 12 months
PROMIS Depression (v1.0), Anxiety (v1.0), Social Isolation (v2.0)
Computer Adaptive Testing measures of psychosocial well-being.
Higher scores mean a worse outcome (i.e., more anxiety or depression). Scores can range from 9-85, and a t-score of 50 represents the mean score for the United States general population with a standard deviation of 10.
Measured: baseline and 3, 6, 12 months post-baseline
Secondary outcomes (3)
Biological Age: DNA methylation GrimAge
Biological age as defined by DNA methylation GrimAge, an estimation of biological age in units of years.
Measured: Baseline, 3 months, 12 months
ECG-age (electrocardiogram-age)
Artificial intelligence algorithm using electrocardiogram data to estimate participant's age in unit of years. Higher ECG-age equates to greater cardiovascular aging.
Measured: Baseline, 3 months, 12 months
Telomere Length
Telomere length measures cellular aging, measured in kilobases (kb). Longer telomere length indicates less cellular aging (a better outcome).
Measured: Baseline, 3 months, 12 months

Questions about this trial
What is this clinical trial studying?
A study testing Positive Emotion Skills Intervention in people with Aging and Aging, Healthy, run by Northwestern University at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 30 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Patient-Reported Outcomes Measurement Information System (PROMIS) Positive Affect (v1.0) and PROMIS Meaning and Purpose (v1.0) (time frame: Baseline, 3 months, 6 months, 12 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07334106, which also lists 7 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Oct 2026; AzTrials last refreshed its copy on 8 Nov 2026.
