HgbA1c |
HgbA1c is regarded as the standard laboratory measurement (blood test) for assessing the control of diabetes over approximately three months preceding the test. HgbA1c is usually checked several times a year in patients with poorly controlled diabetes. |
At the baseline (Pre-CVT visit interview) and post-intervention (Post-CVT visit interview). All available values were restricted to one year before Baseline (Pre-Visit Interview) and from 30 days to 6 months past Post-CVT visit Interview. |

Communication Self-efficacy |
Communication Self-Efficacy (pre and post visit) is the degree to which a patient feels able to interact with his/her provider in order to provide information about problems, obtain desired information about diagnosis, treatment and prognosis, and participate in formulating a plan. The Perceived Efficacy in Physician-Patient Interactions scale (PEPPI) is a valid and reliable measure of patients' perceived self-efficacy in interacting with physicians (alpha 0.83). The short form of the PEPPI (PEPPI-5) has 5-items. Score on the PEPPI-5 ranges from 5-25. Higher scores reflect a better perceived self-efficacy in interacting with physicians. |

Consultation Care Measure (CCM) |
Consultation Care Measure (CCM) assesses patient-centered care and patient-centered communication. Patients rate such factors as their providers' (1) communication and partnership, (2) personal relationship, (3) health promotion, (4) positive and clear approach to problem, (5) interest in effect on life on a 21-item scale, each item scores from 1 (strongly disagree) to 5 (strongly agree). Scores can range from 21 to 105. The higher scores mean a better patients' experiences with their provider. |

Adherence (Self-reported) |
Self-reported adherence is measured using a brief questionnaire - a general measure of adherence to providers' recommendations and includes 5 items and is scored on a 6-level Likert-type scale ranging from "none of the time" to "all of the time". Scores range from 0-100 (after normalizing the standard 6-30 range) with higher numbers reflecting better adherence. Adherence using this measure is assessed with a brief telephone survey 4 weeks following the visit. |

Medication Adherence (MPR) |
Medication adherence will be assessed with a medication possession ratio (MPR) for diabetes medications. |

Consultation and Relational Empathy (CARE) |
Consultation and Relational Empathy (CARE) Measure - is a tool for measuring patients' perceptions of relational empathy in the consultation. In this 10-item questionnaire patients rate the statements about their doctor's understanding their concern, showing care, and etc. during the recent CVT visit on a scale from 1 to 5 where 1 is "poor" and 5 is "excellent". Scores can range from 10 to 50. The higher score means a better patient's perception of empathy in consultation. |

Communication Ratings |
The questionnaire assesses patients' ratings of their own participatory communication behavior and patients' ratings of their providers' communication. It is a 15-item scale with 3 sub-scales. Patients' ratings of their (1) providers' informativeness and the extent to which the patient understands that information (information sub-scale) are measured with 5-items; (2) patients' ratings that the provider values and respects them is measured with 5-items; and (3) patients' ratings of their own communication is measured with 5-items. This questionnaire has high internal consistency. The scale is scored from 1 (completely disagree) to 7 (completely agree). The total scores range from 15 to 105. The higher scores indicate a better quality of communication. |

Human Connection Scale |
Human Connection Scale is a 15-item questionnaire that measures the extent to which patient feel a sense of mutual understanding, caring, and trust with their physicians. The scale is a valid and reliable measure of therapeutic alliance between patients and their physicians. The score from 1 to 4 is used where 1 is "not at all" and 4 is "extremely". The scores range from 15 to 60. The higher scores indicate higher therapeutic alliance between patients and physicians. |
At the baseline (Pre-CVT visit interview) and post-intervention (Post-CVT visit interview) |

Resistance to Treatment Questionnaire (RTQ) |
Resistance to Treatment Questionnaire (RTQ) identifies the reasons for resistance to treatment and its intensity among patients with diabetes. 20-item questionnaire consists of four themes (lack of faith or dissatisfaction, emotional reasons, specific problems, factors connected to despair or failure) containing 5 items each; each item is scored from 1 (strongly disagree) to 5 (strongly agree). The scores range from 20 to 100. The higher scores mean more barriers to treatment (a worse outcome). |

Trust in Provider Questionnaire |
Trust in Provider is an important characteristic of provider-patient relationships and is assessed with a questionnaire. Trust is measured pre- and post-CVT visit using a 9-item measure. The scale is scored on a 7-point Likert scale using the anchors "strongly disagree" and "strongly agree". The scores range from 9 to 63. The higher scores mean a better trust in provider. |

Patient Satisfaction |
Patient Satisfaction is assessed as the extent to which the patient is content with the relationship with her/his provider, in terms of the quality of information exchanged during medical encounters, and in terms of the demeanor of the provider toward the patient (courtesy, respectfulness, sensitivity, taking time and not being rushed). This is a 4-item survey, patient's satisfaction is scored from 1 (not at all satisfied) to 7 (extremely satisfied). The scores range from 5 to 35. The higher score indicates a better patient satisfaction. |

Participatory Decision-Making |
Participatory Decision-Making Style represents the degree to which providers involve patients in decision making. We measure patients' ratings of providers' participatory decision-making style using a 4-item scale evaluated by Heisler et al. in a study of veterans with diabetes. The authors found it to be associated with better patient understanding of diabetes and self-management practices. The survey scores how often provider involves patient in decision-making on a scale from 1 to 5, where 1 is "none of the time" and 5 is "all of the time". Scores range from 4 to 20. Higher scores mean a better outcome. |

Diabetes Self-Efficacy |
The investigators used a 4-item scale to measure patients' confidence in their ability to manage their diabetes. The survey scores patients' perception of how well they can handle their diabetes on a scale from 1 to 7, where 1 is "not at all true" and 7 is "very true". The scores range from 4 to 28. The higher score is validated as a predictor of better glycemic control. The higher scores mean a better confidence in managing diabetes. |
