We propose a sample size of 50 subjects for each of the cohorts. Pairwise comparisons of mean knowledge scores of Cohort 2 with Cohort 1 (i.e., the original cohort taking the test prior to any educational intervention) will be conducted using two-sided t-tests to detect a p-value of < 0.05. Adjustments will be made for demographic factors known to be related to chronic disease knowledge, including age, race, gender and education. The effective sample size will provide 80% power to detect a difference in mean knowledge scores of 3 or more questions.
