Impact of Race Versus Education and Race Versus Income on Patients' Motivation to Participate in Clinical Trials.
Our study investigates whether levels of motivation and barriers to participation in clinical trials vary with patients' education and income. A self-administered survey asked outpatients to rank potential influential factors on a "0" to "4" significance scale for their motivation to participate in clinical trials. Principal component analysis (PCA), analysis of variance (ANOVA), Kruskal-Wallis, and Mann-Whitney U tests analyzed the impact of race, education, and income on their motivation to participate. Analysis included 1841 surveys; most respondents had a high school education or some college, and listed annual income < $30,000. There was a significant interaction between race and income on our motivation scale 1 scores (p = .0261). Compared with their counterparts, subjects with less education/lower income ranked monetary compensation (p = .0420 and p < .0001, respectively) as a higher motivator. Minorities and patients with less education and lower income appear to be more influenced by their desire to please the doctor, the race and sex of the doctor, and the language spoken by the doctor being the same as theirs. For all races, education appeared to have a direct relationship with motivation to participate, except for African-Americans, whose motivation appeared to decline with more education. Income appeared to have an inverse relationship with motivation to participate for all races.
