TARDIS - Photo Elicitation and Intervention

Background and Significance: An estimated 20-25% of Veterans are diagnosed with diabetes, an incidence three times higher than the national rate. Treatment and management of poorly self-managed diabetes is costly as medical care costs are 2.3 times higher for individuals with diabetes than for those who do not have the disease. Regular preventative care is essential to prevent comorbidities and maintain optimal health. Individuals with T2D provide 99% of their own care; self-management of T2D is person-specific and ever-present. Consistent and sustained self-management decreases comorbidity development, and positively influences quality of life and psychosocial outcomes. Inconsistent self-management increases the risk of poor health outcomes including microvascular and/or macrovascular problems and psychosocial complications. Yet rates of self-management remain sub-optimal.

T2D self-management is omnipresent, inescapable, and burdensome. A Veteran may become overwhelmed and/or frustrated because of the amount and frequency of T2D self-management behaviors, and these negative feelings may lead to inattention to critical self-management behaviors such as eating healthy or blood glucose checks. Veterans often experience challenges to self-management despite knowing the importance of these behaviors. Self-management challenges include limited access to a healthcare provider, unreliable transportation, limited knowledge of healthy food options, beliefs about T2D medications, or a lack of support. Additionally, diabetes distress (DD) and other psychosocial factors (i.e., depression, post-traumatic stress disorder) negatively influence an individual's engagement in self-management and health outcomes. Due to the inherent complexity of T2D self-management, the investigators propose that tailoring on DD is one way to focus the provision of tailored self-management information and connections to supportive services. Diabetes distress encompasses the cognitive, physical, and affective experience of living with T2D. Diabetes distress occurs when an individual is overwhelmed with T2D, related self-management behaviors, and knowledge that T2D is progressive and incurable. Diabetes distress is subjective and person-specific; and while DD may fluctuate over time, DD may be continually present. Undiagnosed and untreated DD, may be one cause of a Veteran's poor self-management, thus resulting in poor health outcomes.

Diabetes distress is commonly assessed via the Diabetes Distress Scale or the Problem Areas in Diabetes Scale. Research indicates both measures demonstrate the construct of DD is distinct from general anxiety, stress, and depression. Both the Diabetes Distress Scale and Problem Areas in Diabetes scales assess DD in several domains, and each DD domain addresses a separate aspect of the burden of T2D. The Diabetes Distress Scale measures DD in four domains (i.e., regimen, emotional, interpersonal, healthcare provider), and the Problem Areas in Diabetes Scale assesses DD using similar domains (i.e., emotional, diabetes management, treatment, and social support burden). The Diabetes Distress Scale and Problem Areas in Diabetes Scale have demonstrated content validity in measuring an individual's perception of the resources available, or not available, for self-management. Diabetes distress is associated with more T2D complications, increased stress, being prescribed insulin by a healthcare provider, poor diet and exercise, inadequate support environments, and is more prevalent among women. Diabetes distress levels correlate with self-management behaviors such as monitoring one's diet, engaging with providers, and monitoring one's blood glucose. High to moderate levels of DD are related to poorer glucose regulation, higher HbA1c, lower medication adherence, and poorer quality of life. Individuals with DD report diabetes-related physical burden, health care system distress, and distress with comorbid conditions. In this study, the investigators will further examine the Veteran's experience of DD.

The TARDIS grant and the prior work done for TARDIS was based upon the original Diabetes Distress Scale (DDS) and the four domains within that scale. Those domains include: regimen, provider, interpersonal, and emotional. In 2022, the authors of the Diabetes Distress Scale published an updated version of the DDS called the Type 2 Diabetes Distress Assessment System (T2D-DDAS). The T2D-DDAS contains core and source items that contribute to DD. The T2D-DDAS sources include: hypoglycemia, long-term health, health care provider, interpersonal issues, shame/stigma, healthcare access, and management demands. The sources or facets of DD the investigators identified in the TARDIS foundational work are reflected in the T2D-DDAS. Of note, the investigators identified several additional facets of DD in our work such as pain, military experience, living with comorbidities, and being a caregiver. The scoring for low, moderate, and high DD in the DDS and the T2D-DDAS is the same. For the TARDIS intervention, the investigators will be focusing on the domains of DD as measured by the DDS and not the sources of DD as measured by the T2D-DDAS. The DDS is in the Cerner electronic health record (EHR) and is being used in the VA and the foundational TARDIS work uses the DDS.

Aim 3a: Visual Based Qualitative Methods Visual-based qualitative methods will help us identify and more robustly describe DD in Veterans and will expand on what the investigators have learned thus far in cognitive and semi-structured interviews. Veterans will have the autonomy to select photos that impact, either positively or negatively, their DD and diabetes self-management behaviors. Veterans who participate in the project may want to share their experiences because this is their personal story which they want to share to help other people. The Veteran has the autonomy to decide what, and how much, information to share.

Aim 3b: TARDIS Intervention The TARDIS intervention builds upon data collected in Aim 3a. Health coaching is a person-centered approach to identifying health goals, challenges to these goals, and then developing strategies to address these challenges. For the purposes of TARDIS, interactions are 1:1 between a 'coach', or someone who has received training in motivational interviewing, and a Veteran with type 2 diabetes mellitus (T2DM). This personalized approach can help elicit, understand, and address the experience of DD, and its impact on T2DM self-management, in Veterans with T2DM. With personalized, Veteran-centric information and support, a Veteran may be more equipped to implement self-management to overcome his/her personal modifiable challenges to engaging in T2DM self-management.
