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

The ADA standards of care encourage heath care providers to engage patients in conversations in order to better understand the barriers of T2DM self-care.¹³ How to best support patients within a primary care multidisciplinary team remains unclear.²⁶ T2DM distress and negative reactions to T2DM, including symptoms of anxiety and depression, are common and may require specific referral to a mental health provider if repeated attempts at T2DM education do not improve self-management and illness biomarkers.²⁷ Thus, integrating these providers and services within the medical setting aims to reach more veterans and potentially meet these standards of care. With our health psychology integrated services, clinically significant decreases in anxiety and statistically significant decreases in depressive symptoms were observed that approached “mild to no” symptoms. Although this was not measured formally, the veterans were not engaging in mental health specialty care historically or during the year of the health psychology intervention. This suggests that health psychology services helped bridge the gap and address these psychosocial needs within the small sample.

For clinical measures, modest decreases were observed for HbA_1c and weight. The authors recognize that these changes may not be optimal in terms of health status. A review of the specific patient-centered goals may illuminate this finding. For example, 1 participant had a goal to consume fewer sugary beverages and achieved this behavior change. Yet this change alone may not equate to actual weight loss or a lower HbA_1c. Furthermore, in the context of T2DM-related distress, maintaining current weight and/or blood sugar levels may be a more realistic goal. An evaluation of the specific patient-oriented action goals and observed progress may be important outcomes to include in larger studies. Moreover, while not significant, the average HbA_1c decrease of about 1% is comparable with traditional T2DM education and should be considered in light of the sample’s significant mental health comorbidities. While landmark intensive glucose control trials illustrate significant benefits in reductions of hyperglycemia and nonfatal cardiovascular disease, these reductions are associated with an approximate 2-fold risk of hypoglycemia.^28-30 Thus, the focus on improved glycemic control has been criticized as lacking meaning to patients in contrast to preventing T2DM complications and persevering quality of life.³¹

Limitations and Future Directions

Noted limitations include small sample size, the range of time, and a broad number of sessions given that the intervention was tailored to each veteran. Conclusions drawn from a small sample may be influenced by individual outliers. Given co-occurring conditions and moderate levels of distress, all participants may benefit from additional support resources.

In addition to these considerations, having a comparison group could further strengthen the study as part of an observational database. A between-group comparison could help clinicians better understand what the interventions offer as well as some individual factors that relate to participation and success with behavior change. In the future, studies with a priori hypotheses could also consider the trajectories of weight and blood sugar levels for extended periods; for example, 6 months before the intervention and 6 months following.³² Given the complexity of comorbid mental health and chronic medical conditions in this sample, it also may be important to measure the relationships between chronic physical symptoms as an additional barrier for veterans to make health behavior changes.

Conclusions

The authors believe that the health psychology interventions offered important support and motivation for engagement in health behavior change that led to reduced distress in this patient group. It remains a challenge to engage veterans with psychiatric conditions in mental health care, and simultaneously for health care systems that strive to reduce costs and complications associated with chronic illness management.³³ Aligned with these broader health care goals, the ADA aims to reduce complications and cost and improve outcomes for T2DM with guidelines requiring mental and behavioral health interventions. The authors believe that health psychology interventions are a personalized and feasible bridge to address engagement, illness-related distress while improving patient-satisfaction and T2DM self-management.
