Identifying Driving Risk Factors in Type 1 Diabetes and Their Reduction Via Internet Program (DiabetesDriving.Com)
This study will recruit drivers with Type 1 diabetes from across the U.S. and assign them to four groups based on their presumed risk level- routine care low risk, routine care high risk, or to one of two Internet interventions focused on reducing hypoglycemia driving. All subjects will be followed for two years to determine whether and which intervention was most effective at reducing hypoglycemia related driving collisions.

- The change in the number of hypoglycemia-related driving mishaps [ Time Frame: 10 weeks and 62 weeks after submitting the first Driving Survey ] [ Designated as safety issue: No ]Driving Surveys will be completed prior to study initiation, immediately after the intervention is finished, and again in one year. Monthly Driving Diaries will be completed each month for the year after the intervention finishes beginning 14 weeks after submitting the first Driving Survey.

Experimental: DiabetesDriving.com intervention
Participants in this arm will receive the DiabetesDriving.com internet intervention intended to help reduce their risk of being in a future collision.
Internet intervention in which participants will complete 6 Cores, or classes over the internet, focusing on risk factors and prevention, detection, and management of hypoglycemia before and while driving.
Experimental: DiabetesDriving.com + Motivational Interview
Participants will receive the DiabetesDriving Internet intervention and two 60 minute Motivational Interview (MI) sessions over the telephone. The MI sessions will take place once before and once following completion of the Internet intervention. This interview will focus on making explicit individual's ambivalence around changing behavior.
Behavioral: DiabetesDriving.com + Motivational Interview
Prior to starting and immediately after finishing the DiabetesDriving.com internet intervention, a one hour motivational interview will be conducted with participants. Internet intervention in which participants will complete 6 Cores, or classes over the internet, focusing on risk factors and prevention, detection, and management of hypoglycemia before and while driving.
The investigators have demonstrated that drivers with Type 1 diabetes have at least twice as many collisions as their non-diabetic spouses, that about half of drivers with Type 1 diabetes have at least one hypoglycemic driving mishap a year, and 5% have at least six such events in a year. However, at this point the investigators can not accurately predict those individuals who will have hypoglycemia driving mishaps, which is one goal of this study. The investigators have also demonstrated that face-to-face behavioral interventions focusing on reducing the occurrence of hypoglycemia have lead to significantly fewer vehicular collisions and citations. The question arises whether such a behavioral intervention, specifically focused on reducing hypoglycemia while driving, can be effectively delivered over the internet.
Participants will first complete an Interest form. This questionnaire is used to determine an individual's presumed risk category (high or low risk). Research staff will use the risk category to randomly assign participants to one of four groups according to the randomization scheme. The four groups include: 1) Routine Care - low risk, 2) Routine Care - high risk, 3) DiabetesDriving.com (DD.com) where they will participate in an Internet intervention, 4) DiabetesDriving.com + Motivational Interviewing (MI) where subjects will receive the Internet intervention and two 60 minute MI sessions over the telephone. The MI sessions will take place once before and once following completion of the Internet intervention (within 7 days). This interview will focus on making explicit individuals' ambivalence around changing behavior.
Individuals assigned to the DD.com and DD.com+MI groups will complete 6 Cores, or classes over the internet, focusing on risk factors and prevention, detection, and management of hypoglycemia before and while driving. Each core will take approximately 30 minutes to complete. Core 0 is a tutorial on how to use the internet program. Core 1 focuses on how to use the Tool Kit; Core 2 focuses on how to be a safer driver in general; Core 3 focuses on how to prevent hypoglycemia from occurring while driving; Core 4 focuses on detecting and treating hypoglycemia during a drive; Core 5 focuses on how to maintain the improvements they have achieved in the previous Core over the next 12 months.
After completing a Core, individuals must wait a week before they can start the next Core. During this time individuals will complete at least three Daily Progress Notes, where they will rate their success at achieving their driving goals established in the previous Core. The Cores will take up to 8 weeks to complete before completing Driving Survey 2.
All participants will complete Driving Surveys and monthly driving diaries. The first Driving Survey (Driving Survey 0) will be available to participants as soon as they are consented. Driving Surveys will then be given at 2 and 14 months after submission of Driving Survey 0. Participants will also complete monthly driving diaries, where they will report their driving experiences for the full previous month. Monthly driving diaries will be available on the first day of the next full month 98 days (14 weeks) after completing the Driving Survey at month 2 and continue for 12 months. Twenty-six months after submitting Driving Survey 0, participants will be emailed for a two year follow-up. They will be asked to complete a brief questionnaire on driving outcomes (collisions, citations, etc.).
