Details and patient eligibility

About

Study participants who receive the I-SIGHT intervention will have higher rates of glaucoma treatment compliance (e.g., medication-taking and refill compliance, return for clinical follow-up) and more positive eye health outcomes at 12-month follow-up than participants who receive the control group intervention.

Full description

The intervention is telephone-based and individually-tailored to participants' compliance knowledge, attitudes, and behaviors; psychosocial predictors of compliance; health literacy; race and culture; and prescribed medication regimen. The intervention calls utilize interactive voice recognition technology to facilitate interest, participation, and interaction with call recipients. We evaluated the intervention in a randomized controlled trial with telephone interviews administered to all participants at baseline, 6, 9, and 12-months

Telephone and print based intervention

Experimental group

Description:

The I-SIGHT intervention consists of twelve interactive voice recognition (IVR) phone calls over a nine-month period and accompanying printed materials that are mailed to participants following each call. The phone call messages and print materials are tailored to individuals' circumstances using data from the screening and baseline interviews. The intervention is based on theoretical constructs from Social Cognitive Theory and the Health Belief Model, and emphasizes self-efficacy, medication taking skills, outcome expectancies, facilitators and barriers to compliance, and social support. The treatment group receives the tailored telephone intervention and mailed, printed materials.

Treatment:

Behavioral: Telephone and Print based intervention

Usual care

No Intervention group

Description:

The control group received usual care at each clinical site and interacted with study personnel only for data collection.
