LINK-IT: Leveraging vIdeos and commuNity Health worKers to Improve Diabetes OuTcomes (LINK-IT)

The overall goal of this study is to examine the efficacy of the video-based Diabetes Self-Management Education and Support (DSMES) (hereafter VIDEO), or the video-based DSMES+community health worker (CHW) intervention (hereafter VIDEO+CHW), compared with a wait-list control group (hereafter CONTROL) to improve glycemic control among Chinese immigrants with uncontrolled Type 2 diabetes in NYC.

Study Overview

• Status: Recruiting
• Conditions: Type 2 Diabetes
• Intervention / Treatment: Behavioral: Video-Based Diabetes Self-Management Education and Support (DSMES); Behavioral: Community Health Worker (CHW) Support

Detailed Description

Participants will be randomized with equal allocation to one of the 3 groups. The VIDEO group will receive 1 DSMES brief video/week for 24 weeks delivered via text message. The VIDEO+CHW group will receive the same DSMES videos plus bi-weekly support calls from a CHW for 24 weeks. The CHW will assess participants' social determinants of health (SDOH) barriers to Type 2 diabetes care and link them to available resources in the community. The CONTROL group will continue to receive their usual care and at the end of the study, they will receive DSMES videos.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: VIDEO; Participants assigned to the VIDEO arm will receive one brief Diabetes Self-Management Education and Support (DSMES) video per week for 24 weeks. The videos will be delivered via text message.	Behavioral: Video-Based Diabetes Self-Management Education and Support (DSMES); The DSMES videos provide important diabetes education to participants and empower them to become an activated patient on the individual level.
Experimental: VIDEO+CHW; Participants assigned to the VIDEO+CHW arm will receive one brief DSMES video per week, in addition to bi-weekly support calls from a community health worker (CHW), for 24 weeks. The DSMES videos will be delivered via text message.	Behavioral: Video-Based Diabetes Self-Management Education and Support (DSMES); The DSMES videos provide important diabetes education to participants and empower them to become an activated patient on the individual level.; Behavioral: Community Health Worker (CHW) Support; CHWs will assess participants' social determinants of health (SDOH) barriers to Type 2 diabetes care and link them to available resources in the community.
No Intervention: CONTROL; Participants assigned to the CONTROL group will continue to receive usual care.

Hemoglobin A1c (HbA1c) Levels	Baseline
Hemoglobin A1c (HbA1c) Levels	Month 6
Hemoglobin A1c (HbA1c) Levels	Month 12

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Stanford Self-Efficacy for Diabetes Scale Score	8-item self-assessment of participants' confidence level in performing specific self-management behaviors. Items are ranked on a 10-point Likert scale ranging from 1 (not at all confident) to 10 (totally confident). The total score is the average of all scores and ranges from 1-10; where higher scores indicate greater self-efficacy.	Baseline

International Physical Activity Questionnaire (IPAQ) Short-Version Score	Self-assessment providing an estimate of the number of minutes per week participants engage in three categories of physical activity: vigorous activity, moderate activity, and walking activity. Results are expressed in metabolic equivalent (MET) minutes per week. MET minutes represent the amount of energy expended carrying out physical activity. The formula for calculating MET is as follows: 8(vigorous activity)(minutes) + 4 (moderate activity)(minutes) +3.3 (walking activity) (minutes) = MET. Higher MET scores indicate higher weekly levels of physical activity.	Baseline

Adherence to Refills and Medications Scale for Diabetes (ARMS-D)	ARMS-D is an 11-item questionnaire used to assess medication-taking adherence at baseline, 6 months, and 12 months. Responses range from 1 ("none of the time") to 4 ("all of the time"). Item scores are summed to produce an overall adherence score ranging from 12 to 48, with higher scores indicating more problems with medication adherence.	Baseline
