This qualitative case study researched the effects of strength-based case intervention on elderly people with palsy who were attending a day-care center in Gyeonggi-do. Over 4 months, the researcher gathered data by reading documents, observing, conducting in-depth interviews with the elders and day-care social workers, and attending the social worker’s group supervision meeting. Analysis yielded several major findings. The steps of strength-based case intervention were delineated and the core of the process was identified as a transformation of perspective. Focusing on the strengths and resources of the clients, along with their unique abilities and inherent value, was found to be effective. Staff-client collaborations were restrained by sociocultural and organizational circumstances however both staff and clients changed as a result of the implementation of the strength-based approach. The study concludes with a discussion of implications.
