Racial/ethnic concordance between patients and researchers as a predictor of study attrition.

ABSTRACT:

Rationale

The differential attrition of racial/ethnic minority participants in clinical research is a major threat to advancing medical and behavioral science.

Objective

Our aim was to examine the influence of racial/ethnic concordance between participants and research staff on study attrition.

Method

Data were pooled from participants and clinical research coordinators (CRCs) in six longitudinal studies of respiratory illness. Dyads were classified as concordant if the patient and CRC were of the same racial/ethnic group. Multilevel modeling examined the effect of racial/ethnic concordance on attrition at the first and one-year follow-ups.
