One participant refused/did not know. Two Hispanic people and one Native American. Note. Mann–Whitney and Fisher’s exact tests identified no association between any variable and inviting a support person. A1c, hemoglobin A1c; BHLS, Brief Health Literacy Screen (limited if score ≤ 9); ARMS-D, Adherence to Refills and Medications Scale for Diabetes medication taking subscale (possible range 7–28; higher scores indicate more adherence); DFBC-II, Diabetes Family Behavior Checklist-II (possible range 1 = never to 5 = once a day); SDSCA, Summary of Diabetes Self-Care Activities (possible range 0–7; it indicates number of days adherent per week); and SMBG, self-monitoring of blood glucose.
