Overcoming Barriers and Obstacles to Adopting Diabetes Devices

Glycated haemoglobin (HbA1c)

The number of participants who withdraw or are lost to followup over the course of the study is used as a measure of attrition

Number of eligible individuals who agree to participate in the study out of all those approached during recruitment

Participant-rated Satisfaction Survey: Individual question scores are presented, each was measured on a Likert scale (0-4), higher scores mean more satisfaction.

Baseline and 3-month followup continuous glucose monitor values for percent time spent between 70-180mg/dl

Unabbreviated Scale Title: Diabetes Distress Scale for Type 1 Diabetes (T1-DDS) is a 28-item self-report scale that highlights seven critical dimensions of distress: powerlessness, management distress, hypoglycemia distress, negative social perceptions, eating distress, physician distress, and friends/family distress. A total score is calculated using the mean of all item scores. Subscale scores are calculated using the means of specific items for each subscale.

Min Value: 1 Max Value: 6 Higher scores mean worse outcome/more distress

Scale title "Glucose Monitoring System Satisfaction Survey - Type 1 Diabetes" Min:1 Max:5 Higher mean scores mean worse outcome

Baseline and 3-month follow-up percentage of continuous glucose monitoring values using data available from device for use in analyses.

Mean glucose level from continuous glucose monitoring data at baseline and month 3

Title: Barriers to Diabetes Device Use is a 19-item list of barriers to diabetes device use. Participants can select between 0 and 19 barriers. Examples of barriers are: cost, insurance, lack of family support, lack of support from the diabetes care team, and not liking devices on the body.

Min: 0 Max: 19 higher scores mean a worse outcome

Title: Diabetes Technology Attitudes Survey, a 6-item survey that asks about general attitudes about the role diabetes technology in one's life and the extent to which someone finds technology helpful for managing diabetes.

Min: 1 Max: 5 Mean Score, higher score means better outcome

Scale Title: Hypoglycemia Fear Survey II - Worry Subscale is an 18-item subscale that presents a list of concerns people with diabetes sometimes have about low blood sugar. Respondents answer based on their level of worry about each item for the past 6 months. A total score is calculated by summing individual item scores.

Min: 0 Max: 4 Higher score indicates worse outcome

Title: Hypoglycemia Confidence Scale is a 9-item scale that asks about how confident the respondent is in managing problems with hypoglycemia in a range of situations. A total score is calculated using the mean of all item scores.

Min: 1 Max: 4 Higher score means better outcome/more confidence

Scale: Technology Use For Diabetes Problem Solving Scale is a 9-item scale that asks participants to rate how often they use different types of technology (eg phone, websites, looking at graphs of their glucose data) in managing their diabetes, solving problems and finding answers to questions that arise in managing diabetes. A total score is calculated by summing all items.

Min: 0 Max: 5 Higher score means a better outcome

Title: INsulin Dosing Systems: Perceptions, Ideas, Reflections, and Expectations (INSPIRE) is a 31-item survey that assesses perceived benefits and burdens of automated insulin delivery systems. A total score is calculated by obtaining a mean score across items, then multiplying the mean score by 25 to scale total INSPIRE measure scores from 0 to 100.

Min: 1 Max: 5 High score means more positive outcome

Frequency will be measured as the number of times a day the participant checks blood glucose level using glucose meter
