Case study is an ideal methodology when a targeted, in-depth investigation is needed (Feagin, Orum, and Sjoberg, 1991). Case studies are a useful tool in exploratory analysis because they are designed to bring out the details from the viewpoint of the participants through the use of multiple sources of data.
The study team used a multiple-case, explanatory-exploratory methodology to investigate policies, services, and well-being for relative child-only cases. The explanatory strategy addresses "how" questions comparing the well-being of children in TANF child-only cases with relative caregivers with other children in relative care and to children in TANF cases with parents. The exploratory strategy addresses "what" questions regarding policies and programs affecting children in TANF child-only cases with relative caregivers, as well as service needs and services received by children in TANF relative caregiver child-only cases.
