Adaptación de FAMS para optimizar el uso de CGM entre adultos emergentes con diabetes tipo 1

30 de octubre de 2026 actualizado por: Lindsay Mayberry, Vanderbilt University Medical Center

The goal of this clinical trial is to evaluate the efficacy of an adapted FAMS (Family/friend Activation to Motivate Self-care) intervention on CGM use among study participants who are CGM users. We will leverage the infrastructure of an NIDDK-funded RCT evaluating FAMS-T1D among N=280 emerging adults with T1D who have elevated hemoglobin A1c or elevated diabetes distress (NCT05820477). We anticipate at least 50% using CGM to be included in these analyses.

Descripción detallada

FAMS (Family/friend Activation to Motivate Self-care) is a mobile phone-delivered intervention, based on Family Systems Theory, which helps adults with diabetes set behavioral goals and improve support received from friends and family for goal success. FAMS includes monthly phone coaching and text message support by FAMS coaches for the person with diabetes (PWD) and the option to enroll a support person (SP) to receive automated texts tailored to the self-care goals the person with T1D sets in coaching sessions. Adaptations specific to CGM include the option to set CGM use goals in coaching (and receive associated text support) and skill-building exercises during coaching to support data sharing relationships (e.g., establishing, setting and adjusting ground rules about communication).

Within the FAMS-T1D RCT (NCT05820477), we will test effects of FAMS-T1D on CGM use use relative to enhanced treatment as usual. We will evaluate effects on CGM use from baseline to post-intervention (6 months) as the primary endpoint. Study start date for the nested trial (NCT05854069) is the enrollment date of the first participant using a CGM. Since the goal of this trial is to assess effects of the adapted FAMS intervention on CGM use, the date participant CGM usage was confirmed is considered the enrollment date.

Intervención / Tratamiento
Experimental: FAMS-T1D

Participants will receive FAMS-T1D components (monthly phone coaching and text message support for goals) for 6 months. Support persons will receive text messages that are tailored to the goal set by the person with type 1 diabetes.

All persons with diabetes will receive text messages regarding how to access their HbA1c results and receive links providing information to assist them in self-care behaviors related to their diabetes. All support persons will also receive materials about type 1 diabetes and how to provide helpful support to the person with diabetes.

FAMS-T1D involves monthly phone coaching that assists individuals in setting specific and time bound diabetes goals with automated text message support to the patient participant and less frequent automated text messages to their support person, if one is enrolled.

Behavioral: Diabetes Resources High quality digital materials about diabetes management will be provided upon enrollment and send to participants quarterly.
