This study was done to explore the process of accepting CATs among nurses who experienced CATs in Korea.

Grounded theory methodology was utilized. Data were collected from 10 nurses during individual in-depth interviews. Theoretical sampling was used until the data reached saturation. Data were analyzed using the constant comparative analysis method.

The core category emerged as "resolving the doubt and integrating" explaining the process of accepting CATs. The nurses engaged in three stages: need awareness, look for solution and integration. Causal conditions were interest as a nursing intervention and orthodox medical limitations. Context was lack of basis for application and increase in social interest. Strategies were new knowledge acquisition, having a strong will, combined with existing knowledge, and individualized intervention. Intervening conditions were others' eye, exhaustion for nurses and physical environment. Consequences were expanding of the nursing role and improved nurse satisfaction.

The results of the study should facilitate application of CATs in nursing practice. To help nurses who are interested in CATs, there is a need for education programs, and further research on CATs.
