Group Education Trial to Improve Transition in Type 1 Diabetes

HbA1c will be measured using an A1c Test Kit, which is a non-fasting, finger stick, whole blood test

Delay greater than 6 months (Y/N) between the last Diabetes Care visit with a pediatric care physician and the first Diabetes Care visit with an adult care physician will be derived from the Physician Service Claims Database (RAMQ) and medical record chart

Time in days between the last Diabetes Care visit with a pediatric care physician and the first Diabetes Care visit with an adult care physician will be derived from the Physician Service Claims Database (RAMQ) and medical record chart

Any diabetes-related hospitalizations in the past 12 months, expressed as number of hospitalizations per person-years (P-Y) at risk will be derived from the Hospital Discharge Database (Med-Echo) and medical record chart

Any diabetes-related emergency-department visits in the past 12 months, expressed as number of emergency department visits per person-years (P-Y) at risk will be derived from the Physician Service Claims Database (RAMQ) and medical record chart

Any patient-reported severe hypoglycemic events in the past 12 months

Presence of stigma defined as an affirmative response to at least one of 3 key items on the Barriers to Diabetes Adherence in Adolescence (BDA) questionnaire stigma subscale (score >2 on a 5-point Likert-type scale)

Self-efficacy for Diabetes Self-Management Measure (SEDM) assesses self-efficacy. The score ranges from 1 to 10. All item scores are averaged to compute the score. A higher score represents a better outcome.

L'Aide aux Jeunes Diabétiques Diabetes Knowledge and Skills Questionnaire assesses diabetes knowledge. The score ranges from 0 to 50. The number of correct items are summed to compute the score. A higher score represents a better outcome.

Am I ON TRAC? For Adult Care Questionnaire (Youth Version of Questionnaire) measures transition readiness. Scores range from 13 to 64 on the Knowledge Scale. Item scores are summed to compute the Knowledge Scale score. Higher scores on the Knowledge Scale represent a better outcome. Raw scores range from 8 to 45 on the Behaviour Index. Item scores are summed to compute the raw scores on the Behaviour Index. Higher raw scores on the Behaviour Index represent a better outcome. Cut-off scores range from 0 to 9 on the Behaviour Index. Threshold scores are summed to compute the cut-off scores on the Behaviour Index. Higher cut-off scores on the Behaviour Index represent a better outcome.

Diabetes Distress Scale for Adults with Type 1 Diabetes (T1-DDS) measures diabetes-related distress. The Total Score ranges from 1 to 6. All item scores are averaged to compute the Total Score. A higher Total Score represents a worse outcome. Scores range from 1 to 6 on the 7 Subscales (1. Powerlessness, 2. Management Distress, 3. Hypoglycemia Distress, 4. Negative Social Perceptions, 5. Eating Distress, 6. Physician Distress, 7. Friend/Family Distress) and Screener. Item scores are averaged to compute the Subscale and Screener scores. Higher Subscale and Screener scores represent a worse outcome.

Pediatric Quality of Life Inventory (PedsQL) Generic Core Scale assesses Health-Related Quality of Life. Scores are transformed on a scale from 0 to 100. The Scale Scores (Physical Functioning, Emotional Functioning, Social Functioning, and School Functioning) range from 0 to 100. To create Scale Scores, the mean is computed as the sum of the items over the number of items answered. Higher Scale Scores represent a better outcome. To create the Psychosocial Health Summary Score, the mean is computed as the sum of the items over the number of items answered in the Emotional, Social, and School Functioning Scales. The Physical Health Summary Score is the same as the Physical Functioning Scale Score. The Total Scale Score ranges from 0 to 100. To create the Total Scale Score, the mean is computed as the sum of all the items over the number of items answered on all the Scales. A higher Total Scale Score represents a better outcome.

Pediatric Quality of Life Inventory (PedsQL) Diabetes Module assesses diabetes-specific quality of life. Scores are transformed on a scale from 0 to 100. The Scale Scores by Dimension (About My Diabetes, Treatment-I, Treatment II, Worry, and Communication) range from 0 to 100. To calculate Scale Scores by Dimension, the mean is computed as the sum of the items over the number of items answered. Higher Scale Scores represent a better outcome. To calculate the Total Score, the mean is computed as the sum of all the items over the number of items answered on all the Scales. A higher Total Score represents a better outcome.
