Diffusion or imitation of intervention (contrast effects). When intervention involves some type of informational program and when clients from different interventions or different practitioners communicate with each other about the program, clients may learn about information intended for others. Example: Harvey was seeing a practitioner for help with his depression at the same time his wife Jean was seeing a practitioner for help with anger management. Although their intervention programs were different, their discussions with each other led each of them to try aspects of each other’s program.
