NCT02414217

Brief Summary

The objective of this project is to test two interventions designed to improve diabetes-related numeracy. Numeracy is the ability to understand and use numbers. People with diabetes use numbers in a variety of ways in managing their condition (e.g., understanding blood sugar values, counting carbohydrates, taking medications at the right dose and time). As part of this project, the investigators developed and pilot tested two interventions to improve diabetes-related numeracy: (1) a series of in-person education classes and (2) a one-time, online diabetes education class. The investigators will look to see whether participants in the education classes show improvements in their diabetes-related numeracy skills, self-care behavior and attitudes, and clinical outcomes (i.e., body mass index, blood pressure, blood sugar \[A1c\]).

Study Arms (3)

In-Person Diabetes Numeracy Education

EXPERIMENTAL

Participants randomized to the in-person education group attended four group classes, each addressing a specific set of diabetes self-care skills (i.e., understanding and using blood glucose numbers, counting carbohydrates, taking medications at the right dose and time). So that each class included a stable group of 8 and 16 participants, we ran classes in "cohorts" of 8-16 people. A participant always attended classes with his/her cohort.

Behavioral: In-Person Diabetes Numeracy Education

Online Diabetes Numeracy Education

EXPERIMENTAL

Participants randomized to the online education group attended a single session, at which he/she completed a computerized education module that addressed understanding blood sugar values and using them to examine the impact of food, exercise, and medicines on blood sugar.

Behavioral: Online Diabetes Numeracy Education

Control

NO INTERVENTION

Participants were given written educational materials about diabetes.
