(PT2T)
What this study is about
Nearly half of adults in the United States have or are at risk of developing type 2 diabetes. The overall goal of this community-engaged research is to examine the effectiveness of an innovative couple-based lifestyle intervention to prevent type 2 diabetes that is applicable to a broad range of partnered adults in the United States.

Nearly half of adults in the United States have or are at risk of developing type 2 diabetes. The overall goal of this community-engaged research is to examine the efficacy of an innovative couple-based lifestyle intervention to prevent type 2 diabetes that is applicable to a broad range of partnered adults in the United States.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- "Target partner" is eligible for the National DPP per CDC eligibility requirements:
- BMI ≥ 25 kg/m² (≥ 23 kg/m² if Asian American), and

- Not currently pregnant, and
- High risk for type 2 diabetes based on: (i) CDC Prediabetes Risk Test score ≥ 5, (ii) clinically diagnosed Gestational Diabetes during a previous pregnancy (for women), or (iii) a blood test result indicative of prediabetes in the past year (i.e., fasting blood glucose 100-125 mg/dl; plasma glucose 140-199 mg/dl measured 2 hours after a 75 g glucose load; or HbA1c 5.7%-6.4%).
- The couple has lived together for 1+ years.
- Both partners are willing to participate in the research.
- Both partners are at least 18 years old.
- Both partners are fluent in English.
Exclusion criteria
- "Supporting partner" has a diagnosis of Type 2 Diabetes.
- Either partner:
- Has a diagnosis of another chronic disease (unless no major events/changes for 3+ months), or
- Is currently on medication or engaged in lifestyle intervention for prediabetes or obesity, or
- Has previously participated in the National DPP, or
- Reports discomfort participating in a lifestyle program with their partner, or
- Reports a low level of relationship commitment (i.e., "4" or lower on a scale from 1 (do not agree at all) to 7 (agree completely) on the item "I want this relationship to stay strong no matter what rough times we encounter."; Owen et al., 2011).

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
