A Task Analysis Study of DECIDE For African American Patients With Type 2 Diabetes

The Task Analysis study of the DECIDE program is phase I (part 1) of a three-part study. Phase II (Part 2) is usability testing, and Phase 3 (Part 3) is the pilot clinical trial. For phase 1, a single group will receive the DECIDE intervention program as investigators conduct a task analysis of DECIDE in preparation for building the web-based version (eDECIDE). In Phase 1, participants will go through the curriculum and will be video recorded to help mimic what should be on the eventual eDECIDE website. One phase 1 is completed a usability testing study will be conducted, which is phase II and involves getting feedback from participants on the actual use of the eDECIDE wireframe prototype through recorded interviews. This web-based version will be used for Phase 3 of the study, which will be the pilot clinical trial (eDECIDE).

Self-management is important for persons with type 2 diabetes for glycemic control. When diabetes is uncontrolled, it is important to get back in control in order to decrease further health complications. New ways of delivering self-management that improve access to treatment are needed. This study will help provide background information on any potential problems and or benefit of using web-based and mobile phone applications (mHealth) for diabetes self-management. In addition, this study will help researchers at University of Kansas School of Medicine create a web-based version of the in-person DECIDE program, known as eDECIDE. Data gathered from the in-person DECIDE group sessions will be used to create a series of events for designing a web-based copy based on several task (current study). Therefore, this study is known as a task analysis.

Task Analysis: This entails documenting observations of an existing system, sequence of tasks, and information flows. High-level tasks are divided into subtasks and operations. Informational sources required in each subtask are also recorded. This technique is a critical step in any software development process to ensure a basic understanding of user needs and requirements necessary for optimal learning. It also provides a perspective on individual differences across patients. Understanding this workflow is critical and will serve as the basis for developing eDECIDE.

Phase II- For the task analysis up to 8 individuals will be recruited to take part in the in-person DECIDE problem-solving curriculum (task analysis), the information learned in the task analysis will help build and test (usability testing) the eDECIDE website, which are both integral to the pilot clinical trial (part 3) which will take place last.

PROCEDURES The current study will administer the DECIDE curriculum to a single group, examine responses, build the website, and then prepare for implementing the pilot clinical trial. The information gathered from this study will provide information about barriers to problem solving for diabetes self-management and perceptions of using a web-based diabetes problem-solving format.

Participants who meet eligibility criteria will take part in 9-weekly sessions on diabetes self-management and problem-solving techniques. The sessions will be recorded by audio and video tape. All audio and video taped recordings will be used to help create the web-based version of DECIDE, known as eDECIDE. All and any personal information that is recorded by audio tape will be removed when transcribing the audio recordings. All personal information such as name and face will be removed and blurred if video recording clips are used in an academic or conference meeting setting. Other personal identifiable information such as date of birth, address, or telephone number will be removed when transcribing and you will be identified by participant id number. The researcher will ask participants questions about their diabetes self-management behaviors; go over problem-solving techniques, and self-management skills. The recordings of the focus group sessions will be destroyed 12 months after publication of the research results.

Task Analysis and usability testing Procedures:

Using information gathered from the task analysis, the research team will develop a wire frame prototype of eDECIDE. A benefit of the prototype is to have a layout of the interface without the distraction of color or visual elements that would normally be a part of the actual webpages.

Once the prototype of the website design is complete, investigators will conduct usability testing (phase II/part 2) to assess the efficiency, ease-of-use, and user satisfaction based on participant feedback. Participant feedback is collected via web camera and online questionnaires. Objective data are collected via logging software designed for usability testing. Usability testing is a step-by-step process conducted several times throughout the design and development process. Results from each test are used to make design recommendations for the eDECIDE website. Once usability testing is complete, the pilot clinical trial (phase III/ part 3) of eDECIDE will begin.

Our long-term goal is to understand how problem-solving skills training (PSST), delivered using web-based and mobile phone technology, can improve diabetes self-management in community populations.
