Purpose: The purpose of this study was to define and clarify the concept of family involvement in nursing homes. Methods: The concept analysis approach of Walker and Avant was used. Eighteen studies from electronic databases met the criteria for selection. Results: In the definition of family involvement, the family continues to visit the elder, forms partnerships and communication with the nursing home staff, and plays a role in caring and decision-making for the elder in the family, even after the elder enters the nursing home.

The consequences occurring as a result of family involvement were: 1) improved quality of life and well-being for the elder, 2) family and staff satisfaction, and 3) quality of care. Conclusion: Definition and attributes of family involvement identified from these results can be applied to develop measures and intervention programs for nursing home elders families.
