Study Protocol 
The purpose of this project was to evaluate the user interface of the Guide to Goals (GTG) application 
for ease-of-use. By observing and analyzing actual user experience with the current version of the app, 
we aimed to learn about its shortcomings. Findings from this phase will be used to make GTG 
application more user friendly. The GTG application was aimed at the following user groups: 1. 
Patients/caretakers 2. Front-desk staff 3. Nurses 4. Certified Diabetes Educators 5. Physicians. In this 
study, we aimed to recruit two participants from each of the five user groups for a one-hour usability 
testing session.  However, due to limitations experienced during the COVID-19 pandemic, only 1 
participant from the patient/caretaker group, 2 front desk staff, 2 nurses, 1 certified diabetes educator, 
and 0 physicians were enrolled, for a total of 6 participants. 
The usability testing session consisted of tasks that were to be performed by the user on the GTG 
application, a post interview, and a post survey.  The specific set of tasks that each participant was asked 
to perform varied between groups.  The following list describes what each group was asked to do when 
performing the tasks on the GTG application (Note: the physician group is not described as 0 
participants were enrolled from this group). 
1. Patient and/or Family Member 
a. On the Patient Login Screen, log in using your last name and session ID provided by the 
research team on the Surveys Screen.

2. Front Desk Staff

c. Add comments needs to be followed up regarding ketosis education in the comments 
for provider text box on the Visit Status Screen. 
d. Add a goal for the patient log out of Goals-to-Guide application. 
After the tasks were performed, an informal semi-structured interview was conducted with each 
participant to explore their experience with the GTG application.  The interview looked at how the 
participants thought the application could be improved and what their thoughts were about the overall 

benefit of such an application. The interview asked the following questions, all of which were elaborated 
on. 
1. How long have you been a patient of this clinic? 
2. What were some of the strengths of the GTG app? Why? 
3. What were some of the weaknesses of the GTG app? Why? 
4. What was the hardest task to perform on the app? 
5. Have you used apps to manage T2D before? 
6. Do you have any concerns regarding the app?  
Finally, the participants were asked to complete a questionnaire to further elaborate on their 
experience with the GTG application. The questionnaire asked the participants to rate their experience 
with the GTG application on a scale from 1 to 6 (1= I strongly disagree, 6= I completely agree) against the 
following criterion:  
1. Guide to Goals will motivate users to increase frequency of incorporating best practices for 
managing Type 2 Diabetes. 
2. Guide to Goals is a user friendly application. 
3. Guide to Goals will facilitate conversation between the various members of the care team. 
4. Guide to Goals was easy to use for the first time. 
5. I will feel comfortable using Guide to Goals during a real visit at Children’s Healthcare of Atlanta
