Transition Readiness (Readiness Assessment of Emerging Adults With Type 1 Diabetes Diagnosed in Youth)
The Readiness Assessment of Emerging Adults With Type 1 Diabetes Diagnosed in Youth (READDY) is a 46-item self-report scale that measures participants' preparation for the transition to adult diabetes care, including: knowledge of diabetes, navigation of diabetes care, management skills and behaviors, and insulin pump skills if applicable. Only 18 items from the 3 subscales [Knowledge (4 items - baseline and 12 mos only), Navigation (13 items, baseline, 6 and 12 mos), Health Behaviors (1 item, baseline and 12 mo only)] will be administered for this study. Items responses range from 0 (haven't thought about it) to 5 (yes, I can do this) and are calculated for a total score (higher = more ready).

The Oelsner MESA COVID-19 - Revised is a 10-item self-report scale that measures participants' social distancing and hygiene behaviors during the COVID-19 pandemic. Participants rate how often they engaged in specific precautionary behaviors at the peak of the pandemic (Spring/Summer 2020) and over the past month. Item responses range from 0 (Never) to 4 (Always) and are calculated for a total score (higher = engaged in precautionary behaviors more frequently).
Collected for young adult participants in both arms (baseline and 12 mo) and Peer Mentors (pre-involvement in study).
COVID-19 Experiences (COVID-19 Experiences Questionnaire for Young Adults with T1D)
The COVID-19 Experiences Questionnaire for Young Adults with T1D (CEQ-YAD) is a 37-item, self-report questionnaire assessing how the COVID-19 pandemic impacted young adults with type 1 diabetes, including items about: (1) overall impact of the COVID-19 pandemic, (2) changes in life circumstances due to the pandemic, (3) self and family exposure to COVID-19, (4) changes in diabetes management due to the pandemic, (5) changes in everyday activities and mood due to the pandemic, and (6) COVID-19 vaccine uptake (number, dates, and manufacturers of vaccines and boosters received; open-text about reasons for not being vaccinated). It uses mixed-methods, including scaled, Yes/No, and open-ended items asking about participants' experiences during the peak of the pandemic (Spring/Summer 2020) and over the past 12 months. A total score is calculated by summing response values from scaled and Yes/No items (higher = most negative/worst impact from COVID-19 pandemic).
Stressful Events (Stressful Event Questionnaire)
The Stressful Event Questionnaire assess the number and types of stressful life events experienced during the past year. Participants are asked to select any stressful life events from a list (for example: financial stressors, legal troubles, change in employment, etc.) and to include any stressful events experienced that are not already listed. A total score is calculated by summing the number of events selected or included by the participant (higher = more stressful live events experienced).
Collected for young adult participants in both arms (baseline and 12 mo), not Peer Mentors.
Social Vulnerability (CDC/ATSDR Social Vulnerability Index)
The CDC/ATSDR Social Vulnerability Index (SVI) uses 15 US census-tract level social variables grouped into four related themes, including (1) socioeconomic status (below poverty, unemployed, income, no high school diploma), (2) household composition & disability (aged 65 or older, aged 17 or younger, older than age 5 with a disability, single-parent households), and minority status & language (minority, speak English "less than well"), housing type & transportation (multi-unit structures, mobile homes, crowding, no vehicle, group quarters). Participants' address-level data collected at baseline are batch geocoded, transforming addresses into geographical coordinates using ArcGIS Pro Desktop software and the Street Map Premium package. Coordinates are intersected with census tract polygons, which can be linked to extant data tables, including variables in the SVI. A tract-level score for each of the four themes and an overall score measuring social vulnerability are obtained.
