Simulation as a tool in family therapy research

The efficacy and validity of simulation for purposes of training and evaluation are well established. Simulation has proven valuable in human behaviour research as well. However, based on the belief that families and other small groups behave differently, many family theorists have concluded that simulation may not be valid for family research despite the fact that some empirical studies showed little difference between simulated and actual families, suggesting that the disparity may not be as great as commonly believed. Ongoing and future studies controlling for 'time together', a dimension presumed to be critical in comparing simulated with actual families, may demonstrate that differences are not sufficiently large to preclude the use of simulated families in family research. Methodological problems are addressed and directions for future research proposed.
