Development of innovative group work practice using the intervention research paradigm

Rothman and Thomas' intervention research (IR) paradigm provides an alternative, developmental research method that is appropriate for practice research, especially at the early stages. It is more flexible than conventional experimental designs, capitalizes on the availability of small samples, accommodates the dynamism and variation in practice conditions and diverse populations, and explicitly values practitioners' insights. This article describes two studies to exemplify how the features of IR methodology are well suited to research on innovative group interventions. In one study, a face-to-face psychoeducational group for patients living with sickle cell anemia and chronic depression was used. The other study used an online job stress support group for social workers. The challenges and opportunities that can arise when applying the IR paradigm to develop new interventions are also discussed.
