Trial Outcomes & Findings for American Sign Language-Accessible Diabetes Education (NCT NCT03980808)

NCT ID: NCT03980808

Last Updated: 2023-07-10

Results Overview

Data were collected using a study-specific, knowledge-based Diabetes Health Literacy measure which included 15 forced-choice, closed-ended questions to allow for a total score ranging from 0 to 15, with higher scores reflecting better diabetes health literacy. Analysis of change of knowledge compared differences between the intervention arm and the control arm as measured by the changes to the composite scores of the knowledge-based test. One factor Analysis of Variance (ANOVA) was used to calculate the differences with an a priori alpha level of 0.05.

Measure
ASL-ADE Intervention Arm
One-half of enrolled participants will view the ASL-ADE video intervention. American Sign Language-Accessible Diabetes Education: Video-based ASL interpreted diabetes educational intervention (ASL-ADE), the content of which will be derived from diabetes health information regarding symptoms and risk factors that are published by the U.S. Centers for Diseases Control and Prevention (CDC) and the National Institute for Health (NIH) National Diabetes Education Program.
Control Arm
One-half of enrolled participants will view a non-health related video approximately the same length as the video intervention. Control Intervention: Non-health related video approximately the same length as ASL-ADE.

PRIMARY outcome

Timeframe: The outcome measure results reflect a comparison of the pre and posttest immediate scores.

Population: Group 1 and Group 2 consisted of adults with and without diabetes who primarily use American Sign Language (ASL) for Communication

Data were collected using a study-specific, knowledge-based Diabetes Health Literacy measure which included 15 forced-choice, closed-ended questions to allow for a total score ranging from 0 to 15, with higher scores reflecting better diabetes health literacy. Analysis of change of knowledge compared differences between the intervention arm and the control arm as measured by the changes to the composite scores of the knowledge-based test. One factor Analysis of Variance (ANOVA) was used to calculate the differences with an a priori alpha level of 0.05.

PRIMARY outcome

Timeframe: The outcome measure results for the Your Health Behaviors measure are a comparison between the pretest and the 30-day follow-up.

Population: The population consists of people with and without Diabetes who were Deaf who rely on ASL for communication.

Data were collected using a study-specific questionnaire titled Your Health Behaviors that measure the frequency of diabetes-related health behaviors for a total score ranging from 7 to 35. Each of the diabetes behaviors (physical activity, work physical activity, cigarettes, smoking cessation, alcohol consumption, vegetable consumption, fruit consumption, grain consumption, junk food consumption, fast food consumption) had multiple choice answers that were scaled from 1 - n, with n being the number of options. The least healthy choice was assigned "1", the most healthy choice was assigned "n". Analysis of change in behavior compared differences between the intervention arm and the control arm as measured by the changes in the composite scores of the behavioral intervention. One factor Analysis of Variance (ANOVA) was used to compare the differences with an a priori level of 0.05.
