Study start date: February 23, 2022Actual date on which the first participant was enrolled.

The study focuses on creating and testing a collaborative care approach for people experiencing homelessness and diabetes (DH). This approach combines motivational interviewing, behavioral activation, education, and psychosocial support to enhance medication adherence, tailored specifically to the experiences of this population. The aim is to improve medication adherence and diabetes self-care, which could eventually lead to better blood sugar control and more efficient healthcare use. The study is important as it addresses a unique context, aiming to meet the unmet needs of people experiencing both homelessness and diabetes. In this study, participants will be randomly assigned to either the D-Homes program or a brief diabetes education group. The study will enroll 54 participants and refine procedures for the randomized trial outcome measures. The acceptability of the intervention will be assessed using the Client Satisfaction Questionnaire, an 8-item version, with higher scores indicating greater satisfaction. Additionally, the study team will track the retention of participants who complete both post-treatment assessment visits, at 12-16 weeks and 24-30 weeks post-treatment, measuring retention as the percentage of enrolled participants completing both assessments.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details
38 patients to be enrolledTotal number of participants that the clinical trial aims to recruit.
Treatment Study
These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

How participants are assigned to different groups/arms
In this clinical study, participants are placed into groups randomly, like flipping a coin. This ensures that the study is fair and unbiased, making the results more reliable. By assigning participants by chance, researchers can better compare treatments without external influences.

Other Ways to Assign Participants
Non-randomized allocation: Participants are assigned based on specific factors, such as their medical condition or a doctor's decision.
None (Single-arm trial): If the study has only one group, all participants receive the same treatment, and no allocation is needed.

How treatments are given to participants
Participants are divided into different groups, each receiving a specific treatment at the same time. This helps researchers compare how well different treatments work against each other.

Other Ways to Assign Treatments
Single-group assignment: Everyone gets the same treatment.
Cross-over assignment: Participants switch between treatments during the study.
Factorial assignment: Participants receive different combinations of treatments.
Sequential assignment: Participants receive treatments one after another in a specific order, possibly based on individual responses.
Other assignment: Treatment assignment does not follow a standard or predefined design.

How the effectiveness of the treatment is controlled
In a non placebo-controlled study, no participants receive an inert substance (placebo) to compare outcomes. Instead, all participants receive either the experimental treatment or an alternative treatment (often the Standard of Care). This method allows researchers to compare the effects of the experimental treatment with those of a different active intervention, rather than a placebo.

Other Options
Placebo-Controlled: A placebo is used to compare the effects of the experimental treatment with those of an inert substance, isolating the true treatment effect.

How the interventions assigned to participants is kept confidential
Participants do not know which treatment they are receiving, but researchers do. This helps prevent bias from participants' expectations while still allowing researchers to monitor the study closely.

Other Ways to Mask Information
Open-label: Everyone knows which treatment is being given.
Double-blind: Neither participants nor researchers know which treatment is given.
Triple-blind: Participants, researchers, and outcome assessors do not know which treatment is given.
Quadruple-blind: Participants, researchers, outcome assessors, and care providers all do not know which treatment is given.

Treatment Groups
Study Objectives
2 intervention groups 

are designated in this study

This study does not include a placebo group 

Treatment Groups
Group I
Experimental
Behavioral treatments by a diabetes wellness coach as defined below.

There will be 10 sessions offered within 12 weeks to participants. Sessions will last approximately 30 minutes. During sessions a diabetes wellness coach will use behavioral activation and motivational interviewing to get to know participants and set goals to improve diabetes care. The coach will encourage a focus on medication adherence behaviors to the extent that participants are willing. The coach will also help with resource and care coordination. The coach will also provide a tailored tool to the patient's needs/goals and tailored diabetes education as needed.

Trained diabetes wellness coaches will provide an approximately 15 minutes of instruction about the basic concepts of diabetes. They will use handouts aligned with American Diabetes Association guidelines. They will read these with participants and answer basic questions. Handouts will cover (1) general diabetes knowledge, (2) healthy eating with diabetes, (3) physical activity with diabetes. The coach will also provide a general tool to support medication adherence (e.g. pillbox).
Group II
Active Comparator
Brief diabetes educational session by a diabetes wellness coach.

Trained diabetes wellness coaches will provide an approximately 15 minutes of instruction about the basic concepts of diabetes. They will use handouts aligned with American Diabetes Association guidelines. They will read these with participants and answer basic questions. Handouts will cover (1) general diabetes knowledge, (2) healthy eating with diabetes, (3) physical activity with diabetes. The coach will also provide a general tool to support medication adherence (e.g. pillbox).
Study Objectives
Primary Objectives

The acceptability of the intervention to participants will be measured by the Client Satisfaction Questionnaire, 8-item version, with a score range from 8-32, higher score indicating higher satisfaction.

The study team will track enrolled participants who complete both post-treatment assessment visits (12-16 week post-treatment assessment and 24-30 week assessment). Retention will be measured as the percentage of enrolled participants who complete both assessments as assessed at 30 weeks.
Secondary Objectives

The study team will measure glycemic control using hemoglobin A1c. This will be done on a consistent, validated point-of-care machine using fingerstick blood samples. The study team will compare glycemic control from baseline to 16 weeks and from baseline to 30 weeks.

Psychological wellness is measured with the 5-item Mental Health Inventory (MHI-5), a brief transdiagnostic screening tool attuned to broader concepts of wellbeing and distress than other available measures. MHI-5 scores are computed and transformed on a 0 to 100 point scale with higher scores indicating more wellness. We compare MHI-5 scores from baseline to 16 weeks and from baseline to 30 weeks.

As measured by the Adherence to Refills and Medications Scales-Diabetes (ARMS-D), Total scores range from 12-48, with higher values indicating worse outcomes. The study team will compare ARMS-D scores from baseline to 16 weeks and baseline to 30 weeks.
