What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This trial tests a 12-week text message program called MASTERY, designed to help adults aged 45 to 64 increase physical activity and reduce stress. Participants receive weekly interactive text sessions and brief phone calls from trainers to set goals and learn stress-reduction techniques. The study compares this program to a control group that gets basic texts and check-ins. Researchers measure changes in moderate-to-vigorous activity using accelerometers at the start, 6 weeks, and 12 weeks.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
A 12-week interactive text message program with weekly two-way sessions and brief trainer calls to promote physical activity and stress reduction.
What this could lead to
If it works, this could offer a simple, low-cost way to help midlife adults become more active and manage stress, potentially reducing long-term health risks.
What could go wrong
This is a small pilot study, so results may not apply broadly. The program depends on participants engaging with texts and calls, and it may not produce lasting changes in activity.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Midlife status (age 45-64 at enrollment). 2. Low baseline physical activity (≤150 minutes/week of MVPA\]) as initially self-reported via the well-validated IPAQ and then confirmed via accelerometer after 7 days of wear. Exclusion Criteria: 1. Existing coronary artery disease (CAD; diagnosed via cardiac catheterization using standard coronary artery stenosis definitions or prior ACS). 2. An unrelated condition limiting physical activity (e.g., ambulation with a cane or walker, recent or planned surgery, or other condition such that ability to increase moderate to physical activity would be limited). 3. Participation in any other programs focused on cardiac prevention or well-being (e.g., cardiac rehabilitation). 4. A cognitive disturbance precluding participation or informed consent, assessed using a six-item screen7 designed to assess suitability for research participation. 5. Inability to speak/write fluently in English. 6. No access to a text message-capable phone.
