Trial Outcomes & Findings for My Diabetes Care Mobile: A Usability Study (NCT NCT04894916)

NCT ID: NCT04894916

Last Updated: 2022-11-10

Results Overview

The System Usability Scale (SUS) is a valid measure of usability and assesses users' perceptions of ease of use, likability of the interface, and overall satisfaction using a 5- point Likert scale (strongly disagree to strongly agree). The ten items are scored on a five-point Likert scale. The item scores are summed and then converted to a score ranging from 0 (worst) to 100 (best). Based on prior research, a score above 68 would be above average and a score of 85 or above suggests excellent usability. The SUS has been used in several studies of patient facing health information technology (the article describing its psychometric properties has been cited over 500 times) and has excellent internal consistency reliability (Cronbach's alpha of 0.91).

SECONDARY outcome

Timeframe: Baseline to one-month follow-up

Population: Participants that completed the study (i.e., used the intervention and complete pre- and post-questionnaires) AND answered all the Short Diabetes Knowledge Instrument items on the pre- and post-questionnaire.

The Short Diabetes Knowledge Instrument (SDKI) is a valid measure of diabetes knowledge with an emphasis on controlling blood glucose through diet, recognizing symptoms of abnormal blood glucose, and using healthy eating to prevent complications. It also includes items on foot care and the importance of physical activity for preventing cardiovascular complications. The SDKI is a uni-dimensional, 13-item scale with scores ranging from 0 to 13 (number of items answered correctly). SDKI demonstrated good internal consistency reliability (Cronbach's alpha 0.73) in a multi-ethnic sample of older adults suggesting the instrument can be used to measure diabetes knowledge in diverse populations (Quandt et al. Diabetes Educator, 2014).

The Perceived Diabetes Self-Management Scale (PDSMS) is a valid measure of diabetes self-efficacy (i.e., how confident they feel about their ability to carry out multiple self management tasks). The uni-dimensional, 8-item scale is scored on a five-point Likert scale. The total PDSMS score can range from 8 to 40, with higher scores indicating more confidence in self-managing one's diabetes.

Population: Participants that completed the study (i.e., used the intervention and complete pre- and post-questionnaires) AND answered all the Problem Areas in Diabetes Scale (PAID-5) items on the pre- and post-questionnaire.

The Problem Areas in Diabetes Scale (PAID-5) is a valid measure of diabetes distress. The five-item, uni-dimensional scale has scores that range from 0 to 20, with higher scores suggesting greater diabetes-related emotional distress. The PAID-5 has excellent excellent internal consistency reliability (Cronbach's alpha 0.86) and is associated with measures of depression and hemoglobin A1c.

Population: Participants that completed the study (i.e., used the intervention and complete pre- and post-questionnaires) AND answered all the items on the Summary of Diabetes Self-Care Activity - General Diet Subscale on both the pre- and post-questionnaire.

The Summary of Diabetes Self-Care Activity (SDSCA) is a 10-item multidimensional instrument to assess levels of diabetes self-care across five domains: general diet (2 items), specific diet (2 items), exercise (2 items), foot care (2 items), and blood-glucose testing (2 items). The general diet subscale is used to assess general diet adherence. The instrument is based on the self-reported days completing recommended activities during the past 7 days. An example item includes "How many of the last SEVEN DAYS have you followed a healthful eating plan?" The general diet subscale score is the mean number of days for the 2 items in the subscale. The score range is from 0 days (worst) to 7 days (best).

The instrument is based on the self-reported days completing recommended activities during the past 7 days. An example item includes "On how many of the last SEVEN DAYS did you test your blood sugar?" The blood-glucose testing subscale is the mean number of days for the 2 items in the subscale. The score range is from 0 days (worst) to 7 days (best).

Outcome measures

Outcome measures
Measure
My Diabetes Care Mobile (MDC-m)
n=51 Participants
Patients have access to a patient web portal embedded with the My Diabetes Care Mobile (MDC-m) intervention. My Diabetes Care Mobile (MDC-m): My Diabetes Care (MDC) is a multi-faceted patient portal intervention for mobile devices that is designed to help patients better understand their diabetes health data as well as promote and support self-management. MDC uses infographics to facilitate patients' understanding of their diabetes health data (e.g., HbA1c, LDL), incorporates motivational strategies and access to an online patient support community, and provides literacy level-appropriate and tailored diabetes self-care information.

Change in Diabetes Self-Care (Self-Monitoring of Blood Glucose Adherence)
One-month Follow-up Post-Questionnaire

Standard Deviation 2.7

SECONDARY outcome

Timeframe: Baseline to one-month follow-up

Population: Participants that completed the study (i.e., used the intervention and complete pre- and post-questionnaires) AND answered all the Adherence to Refills and Medications Scale items on the pre- and post-questionnaire.

The Adherence to Refills and Medications Scale is a reliable and valid measure of medication adherence. The 12-item ARMS has good internal consistency reliability (α=0.81). Responses range from 1="none of the time" to 4="all of the time," and are summed to produce an overall adherence score ranging from 12-48, with higher scores representing more problems with medication adherence.
