Metabolic Indicator [ Time Frame: baseline ]
Metabolic control will be measured as glycosylated hemoglobin (HbA1c) through central laboratory measures (Quest Labs) [78], indicating average glucose levels over the prior three months. The reliability and validity of the lab measures are improved by utilizing a central laboratory for sample analysis (Quest Labs).

Metabolic control will be measured as glycosylated hemoglobin (HbA1c) through central laboratory measures (Quest Labs) [78], indicating average glucose levels over the prior three months. The reliability and validity of the lab measures are improved by utilizing a central laboratory for sample analysis (Quest Labs).
Diabetes Knowledge [ Time Frame: baseline ]
Diabetes knowledge will be measured by the 10 item Spoken Knowledge in Low Literacy for Diabetes scale (SKILLD).51 It takes less than 10 minutes to administer. Coefficients of internal reliability for the SKILLD have been reported at 0.72 (Kuder Richardson Coefficient of reliability) When used to evaluate knowledge in a population of incarcerated persons with diabetes, Cronbach’s alpha was 0.6520-.0.70 respectively.7,6 Content validity was confirmed in previous research by experts in correctional health.

Diabetes-Related Emotional Distress [ Time Frame: baseline ]
Distress will be measured with PAID (Problem Areas in Diabetes) scale, 52with 20 items using a 6-point Likert scale; higher scores indicate higher levels of distress. Internal consistency >0.902.

Self-management behaviors [ Time Frame: baseline ]
Self-management behaviors will be assessed using the Summary of Diabetes Self-Care Activities (SDSCA) .53 This 11-item questionnaire assesses the frequency of health behaviors over the last week, including diet, exercise, blood sugar testing, foot care, and smoking. The instrument has acceptable internal consistency

Perceived Competence Scale [ Time Frame: baseline ]
The 4-item PCS assesses the degree to which participants feel confident of meeting the challenges of DSM. A person’s score on the PCS is calculated by averaging responses on the four-item 7-poins Likert scale with higher scores indicating higher perceived competence. Alpha reliabilities have been reported as above 0.80.
