The validity of self-reported physician utilization measures.
Respondents' reports of outpatient medical care use in the preceding year are compared with actual utilization. The authors examine the predictors of the discrepancy between reported and actual utilization as well as the extent to which reporting error biases models of utilization behavior. The average reporting error in this study is relatively small, but the impact of biased reporting on prediction models can be substantial.
