An interventional study of Group I (WhatsApp) motivational and educational messages delivered periodically and Group II: To implement the SMART method in Diabetes Mellitus, Type 2/Prevention & Control, Diabete Type 2 and Treatment Adherence, sponsored by Instituto Mexicano del Seguro Social. Completed at 1 site in Mexico. Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2026-09-24.

Registry
Diabetes Mellitus — the first condition term the registry derived for this study.

Diabetes Mellitus, Type 2
Why
  1. The study's listed conditions name Diabetes Mellitus, Type 2, a narrower term within Diabetes Mellitus.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study arms

  • Experimental
    Group I received WhatsApp messages

    Group I: Participants received behavioral training and education on T2D, treatment adherence, and polypharmacy, along with the messages shown below via WhatsApp. Positive reinforcement messages were sent once every two days for two weeks, followed by one per week for three weeks.

    Other: Group I (WhatsApp) motivational and educational messages delivered periodically

  • Active comparator
    Group II underwent the SMART S(Specific), M(Measurable, A(Achievable), R(Relevant), T(Timetechnique

    Group II: To implement the SMART method, the patient was first given an explanation of the concept of a goal or objective, as well as what each of the concepts of the SMART method entails. The participant was then asked to identify a goal that meets the SMART criteria and, above all, is measurable.

    Other: Group II: To implement the SMART method

Individual participant data

Plan to share: No — The data was collected by Dr. Raúl Jaimes Salgado, who assigned a code to each patient. The data will be recorded on a data collection form and entered into an Excel spreadsheet with the assistance of Drs. María Magdalena Valencia Gutiérrez and María del Pilar Rodríguez. María Magdalena Valencia will then analyze the data.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Nov 2024 to primary completion in Dec 2025, 13 months.

Of 2,068 non-industry interventional studies with no phase under Diabetes Mellitus, Type 2, half reached primary completion within 21 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 40. This study's 13 months is below that.

Counting every sponsor, half of 2,245 studies reached it within 21 months; a quarter within 10 and three quarters within 38.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 24, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
