What is The Glaucoma Treatment Compliance Assessment Tool (GTCAT)?

We used the framework of the Health Belief Model to create the Glaucoma Treatment Compliance Assessment Tool (GTCAT), a questionnaire designed to evaluate multiple behavioral factors associated with glaucoma medication adherence. The Glaucoma Treatment Compliance Assessment Tool includes 47 statements with a 5-interval Likert-type scale response with anchoring definitions (eg, 1 = strongly disagree, 5 = strongly agree) and contains language at a 6th grade reading level as shown by a Flesch-Kincaid reading level of 5.7 and reading ease of 72.1 (11 to 12 year-old level). We tested the psychometric properties of the GTCAT in multicenter studies (see below Bibliography).

We also developed a short version of the GTCAT, the GTCAT Short (GTCAT-S), which consists of 27 statements. The GTCAT-S is also available upon request.

Do I have to pay to use the GTCAT?

The GTCAT is available free of charge upon approval of your request.
