Enhancing Diabetes Self-Management Education and Psychological Services for Veterans With Comorbid Chronic Health and Mental Health Conditions

Veterans have a higher prevalence of type 2 diabetes mellitus (T2DM) when compared with their civilian counterparts with an overall prevalence rate of 25%.¹ This higher prevalence is similar to other major chronic health conditions, including heart disease and arthritis, with additional costs for disease self-management.² Psychological and behavioral change strategies are a principal means of limiting the severity and even restoring function once T2DM is diagnosed.³ More broadly, there is mounting evidence that addressing distress and behavior change are important across many conditions, particularly T2DM.⁴ Therefore, the US Department of Veterans Affairs (VA) has established patient education and multidisciplinary interventions to optimize engagement in T2DM self-management and health behavior change.⁵

Traditional T2DM education programs aim to meet the American Diabetes Association (ADA) standards of medical care and include a T2DM educator and other allied health professionals. ADA Standard 1.2 emphasizes “productive interactions between a prepared, proactive care team and an informed, activated patient.”⁶ Thus, to attain ADA accreditation, educational programs require instructors to teach about T2DM while engaging patients to help them set and achieve recommended changes. The requirements emphasize setting specific goals, (ie, eating wisely, being physically active, monitoring blood sugars or taking medications). The care team also helps to identify barriers, and at a required follow-up class, patients evaluate how well they met goals and make modifications if needed. The impact of traditional patient education programs to improve glycemic levels is well established.⁷ Importantly, veterans with comorbid mental health conditions may not experience the same beneficial outcomes if or when they participate in traditional diabetes or self-management programs.^8,9 Veterans with T2DM may be particularly vulnerable to chronic stress and effects of comorbid mental health diagnoses.¹⁰ Furthermore, when individuals experience T2DM-related distress, associations with poor health outcomes, including elevated hemoglobin A_1c (HbA_1c), are observed independent of depression.¹¹

Health psychology services integrate into medical settings and strive to reach veterans who may not engage in traditional mental health clinical offerings.¹² These collaborative interventions focus less on diagnostic or screening procedures and more on a patient’s understanding of illness and ability and willingness to carry out treatment regimens. Given the significant roles of distress and co-occurring conditions, health psychology services further aim to provide psychoeducation about stress management in order to explore and enhance motivation for making a wide range of health behavior changes.

The purpose of this study was to evaluate baseline and follow-up HbA_1c, weight, and psychosocial measures, namely, health-related self-efficacy and T2DM-related distress among a small sample that engaged in integrated health psychology services. The focus of this evidence-based psychotherapy service was to improve T2DM self-care and physical health. The participants were offered cognitive and behavioral strategies for setting and meeting personalized T2DM self-management goals. Importantly, motivational interviewing was used throughout to adapt to the participants’ preferences and needs as well as to maintain engagement.

Methods

Primary care providers referred veterans with T2DM to the Health Psychology service at VA Ann Arbor Healthcare System (VAAAHS). A T2DM diagnosis was verified through electronic health record review. Most common referrals included addressing coping with chronic illness and improving glycemic levels. Veterans were invited to participate in a program evaluation project to monitor health-related changes. All participants provided written informed consent and did not receive incentive or payment for participating. The VAAAHS Institutional Review Board reviewed and approved this study.

Intervention

Veterans met individually with a health psychologist or health psychology trainee to create personalized health and behavioral goals for improving T2DM self-management, overall health, and psychological well-being. This intervention included motivational interviewing, SMART (specific, measurable, action-oriented, realistic, timely) goal setting, behavioral activation, acceptance of T2DM-related physical changes, problem-solving therapy, challenging maladaptive disease-related cognitions, and incorporating values to help find motivation for change. Interventionists took a flexible approach and met in-person in primary or specialty care clinics, over the phone, and through telehealth 1 to 4 times a month, meeting participant preferences, with sessions typically ranging from 45 to 60 minutes. The goal of the study was to disseminate and implement evidence-based behavioral change strategies into a multidisciplinary team format without excluding veterans who would benefit from receiving active treatment. Due to this translational approach, a control group was not included for comparison.

Data Collection

Participants completed study measures at the beginning and end of the T2DM-focused intervention sessions. Demographic variables collected included age, sex, race/ethnicity, highest educational attainment, and whether a veteran was prescribed insulin, service connected for T2DM, concurrent enrollment in other educational programs, and time since T2DM diagnosis. Measures were selected based on their relevance to T2DM psychosocial care and diabetes health outcomes.¹³
