View original scientific description
The primary objective of the STRIVE study is to compare two implementation strategies for Diabetes Prevention Program delivery: an in-person health coach strategy (standard 24 in-person sessions at WIC clinics) vs. a multifaceted technology-assisted health coach implementation strategy (12 in-person sessions at WIC clinics supplemented by technology support) on implementation and health-related outcomes in postpartum women.
Interventions
BEHAVIORAL
In-person health coach delivery of the GLB
Delivery of 24 health coaching sessions in-person by health coaches over 1 year. Standard delivery of 24-sessions of the Group Lifestyle Balance (GLB) behavioral intervention in WIC clinics. The GLB was adapted from the original Lifestyle Balance behavioral intervention used in the original Diabetes Prevention Program trial for use in community translation and group settings. It focuses on improving diet and physical activity and promoting moderate weight loss through health coaching on behavioral change, including self-monitoring of food intake, physical activity, and weight.
BEHAVIORAL
Technology-assisted health coach delivery of the GLB
Delivery of 12 health coaching GLB sessions in-person by health coaches over one year; supplemental technology support, including tools for self-monitoring, health coach monitoring, asynchronous delivery of intervention materials, and asynchronous coach and group connection. The GLB was adapted from the original Lifestyle Balance behavioral intervention used in the original Diabetes Prevention Program trial for use in community translation and group settings. It focuses on improving diet and physical activity and promoting moderate weight loss through health coaching on behavioral change, including self-monitoring of food intake, physical activity, and weight.
Primary outcome measures
Difference in uptake (primary implementation outcome)
Time frame: Measured from baseline to 12 months
The primary implementation outcome will be the difference between study arms in a composite uptake score, as defined by a composite score consisting of the percent of sessions attended and the percentage of times in which participants record weight, activity, and diet compared to what is recommended by the intervention.
Difference in mean 12-month weight reduction (primary health-related outcome)
Time frame: Measured at 3, 6, 9 and 12 months
The primary health-related outcome will be difference in mean weight reduction from baseline to 12 months between study arms

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.
