Clinical applications of analogue behavioral observation: dimensions of psychometric evaluation

Clinical assessment applications of analogue behavioral observation are discussed in the context of psychometric principles. Analogue behavioral observation involves the measurement of a client's overt behavior in a contrived situation that is analogous to situations that the client is likely to encounter in his or her natural environment. The goal of analogue behavioral observation is to derive valid estimates of the client's behavior in a current or future natural environment. Analogue behavioral observation instruments are often developed with insufficient attention to their psychometric properties, particularly content validity. Psychometric evaluative dimensions vary in their importance, as a function of the goals of the assessment. Although analogue behavioral observation instruments can be sensitive to change, their validity can erode over time and is affected by numerous sources of variance. Analogue behavioral observation assessment may be especially useful in detecting important functional relations in clinical assessment.
