title: Methodology in consultation-liaison research: a classification of biases.
abstract: Methodology is receiving overdue attention in psychiatric research. This article focuses on biases encountered in studies in consultation-liaison psychiatry. A classification of biases derived from epidemiology is presented, and the expected impact of each bias is discussed. Methods to minimize bias in the design and implementation of consultation-liaison research are suggested.
