Subjects will be divided into cohorts based on follow-up care seeking behavior: 1) those who come in for regular screening defined as at least once per year, 2) those who came in once and were lost to follow-up, 3) those who came in for more than one screening visit and were then lost to follow-up, and 4) those who were previously lost to follow-up and then began coming in for screening again. Questionnaire responses will be compared across cohorts to determine which variables differ significantly. t-Tests, one way, and multivariate analysis of variance, and correlation analysis will be used as indicated by variable type.
