Randomized Controlld Trial of Dementia Education Resources for Action (DERA)

May 7, 2026 updated by: Y. Alicia Hong, George Mason University

Evaluation of Dementia Education and Resources for Action

The goal of this intervention trial is to evaluate the effectiveness the online training program Dementia Education and Resources for Action (DERA) in improving Alzheimer's disease and related dementia-(ADRD) knowledge, stigma, and service-related self-efficacy among community health workers (CHWs). We hypothesize that participants who have completed the DERA will have improved ADRD knowledge and self-efficacy in related service and reduced stigma against ADRD and people affected.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Immediate DERA Intervention
Participants assigned to this arm will receive immediate access to the DERA online training program. The program is web-based platform and includes 7 structured modules on dementia knowledge, stigma reduction, and the role of community health workers in supporting individuals with dementia and their caregivers.
Behavioral: DERA Online Training Program
The Dementia Education and Resources for Action (DERA) program is a structured, online training intervention designed for community health workers. The program consists of approximately 7 sessions delivered through a web-based platform. Content includes dementia fundamentals, early signs and risk factors, stigma reduction, and strategies for communication, support, and service navigation. The training incorporates video-based instruction, interactive materials, and quizzes to support learning and engagement.
No Intervention: Waitlist Control
Participants assigned to this arm will not receive access to the DERA program during the study period. They will complete baseline and post-intervention assessments over a similar timeframe as the intervention group. After completion of the post-intervention assessment, participants will be provided access to the DERA training program.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Dementia Knowledge
Time Frame: Baseline to post-intervention (approximately 6-8 weeks)
Dementia knowledge will be assessed using the Dementia Knowledge Assessment Scale (DKAS). The DKAS is a validated instrument that measures knowledge across multiple domains, including causes, symptoms, risk factors, and care considerations. DKAS-25 total score ranges from 0 to 50. Items are scored 0-2, with higher scores indicating greater dementia-related knowledge.
Baseline to post-intervention (approximately 6-8 weeks)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Dementia-Related Stigma
Time Frame: Baseline to post-intervention (approximately 6-8 weeks)
Dementia-related stigma will be assessed using an adapted 8-item stigma scale with response options ranging from strongly disagree to strongly agree. Total scores range from 8 to 40, with higher scores indicating greater dementia-related stigma.
Baseline to post-intervention (approximately 6-8 weeks)
Self-Efficacy in Dementia Care
Time Frame: Baseline to post-intervention (approximately 6-8 weeks)
Self-efficacy will be measured using a study-specific Community Health Worker Dementia Role Self-Efficacy Scale assessing confidence in performing dementia-related tasks, including education, communication, support, and service navigation. Response options range from "Not at all confident" to "Extremely confident." Total scores range from 8 to 40, with higher scores indicating greater self-efficacy in dementia-related service delivery.
Baseline to post-intervention (approximately 6-8 weeks)
