OBJECTIVES: Diabetes is challenging to manage, with poorly controlled disease having a serious impact on patients’ overall well-being. Individuals vary in interpersonal characteristics and their ability to be self-reliant, termed as attachment style. Attachment theory provides the conceptual framework for these interpersonal differences that can lead to differences in seeking care and disease management. The objective of this study is to assess if variation in attachment style is associated with social support, self-care, and diabetes-related quality of life (QOL) in Veterans.  METHODS: Patients seeking care at the local VHA during FY 2010 with a recorded HbA1c level were randomly selected from administrative data, and surveys mailed.  126(38%) respondents returned surveys.  Self administered survey included validated measures on diabetes self-care, diabetes-related QOL (Diabetes-39), medication adherence, social support, and patients experience with the healthcare system (EHC).   Attachment style measured using the Relationship Style Questionnaire, scores individuals on continuum using two models, self-model, and others-model.  Higher score on self-model indicates individuals with positive view of self, while higher score on others-model indicates positive view of others.  Linear regression was used to assess association of health outcomes with attachment style. RESULTS: Participants were predominantly white (63%), married (60%), and did not depend on a family member or friend for daily activities (83%).  63% of diabetics had at least one family member diagnosed with diabetes. Individuals with high social support reported better EHC, more frequent glucose monitoring, and greater medication adherence.  More positive view of self was associated with lower diabetes-related distress, and higher diabetes-related QOL.  More positive view of others was associated with better social support.  Results for attachment style held even after adjusting for age, gender, race, and education (p<0.05).  CONCLUSIONS: Social support varies by attachment style which could affect diabetes-related QOL.  Interventions to improve diabetes-care should consider patients’ attachment style.
