Joint Patient and Caregiver Intervention for Older African Americans With Type 2 Diabetes

July 25, 2025 updated by: Aprill Z. Dawson, PhD, MPH, Medical College of Wisconsin

Joint Patient and Caregiver Intervention for Older African Americans With Poorly Controlled Type 2 Diabetes (Joint Home-DM-BAT)

This study will test the preliminary efficacy of a joint patient/informal caregiver telephone-delivered intervention that includes diabetes education; problem solving around social needs; and behavioral activation for older African Americans with poorly controlled type 2 diabetes by randomizing 100 patient/caregiver dyads to the Joint Home intervention (n=50) and usual care (n=50) arms.

The aims of the study are:

Aim 1: To test the preliminary efficacy of home-based, joint patient and caregiver intervention (Joint Home-DM-BAT) on patient clinical outcomes (hemoglobin A1c, blood pressure, and LDL-Cholesterol).

Aim 2: To test the preliminary efficacy of home-based, joint patient and caregiver intervention (Joint Home-DM-BAT) Joint Home DM-BAT on patient quality of life.

Aim 3: To test the preliminary efficacy of home-based, joint patient and caregiver intervention (Joint Home-DM-BAT) on caregiver quality of life and caregiver burden.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

  4. Able to communicate in English; and
  5. Has an informal caregiver (family member or close friend willing to participate in the study for 6 months.

Caregiver Inclusion Criteria:

  1. Willing to attend 4, one-hour sessions with the study participant;

Design Details

  • Primary Purpose: Health Services Research
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Double

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Joint Home-DM-BAT Intervention
A trained health educator will deliver the manualized Joint Home-DM-BAT intervention. Participants will receive 8-weekly sessions of diabetes education, problem solving around social needs, and behavioral activation via telephone; and 3 monthly booster sessions.
Behavioral: Joint Home-DM-BAT Intervention
8 weekly sessions of telephone-delivered, manualized education on diabetes management, problem solving of social needs, and behavioral activation.
Active Comparator: Usual Care
Patients randomized to the usual care arm will receive weekly mailings of diabetes education modules for 8 weeks and monthly mailings for 3 months to match the weekly and monthly booster sessions.
Behavioral: Usual Care
Diabetes education materials will be mailed weekly and monthly according to the booster schedule

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Glycemic Control (Hemoglobin A1C [HbA1C])
Time Frame: Change in baseline HbA1C at 6 months post intervention follow-up
About 10cc of blood will be drawn by trained phlebotomists and sent to the lab for testing.
Change in baseline HbA1C at 6 months post intervention follow-up

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
