Qualitative research methodology has become more recognized and valued in diabetes behavioral research in recent years. Qualitative research is very rare in Korea, especially for diabetes; on the other hand, qualitative research is increasing abroad. This paper reviews qualitative research on the life experiences of diabetes patients in Korea. Drawing on advanced research, it is helpful to know the essence of such experiences and the exact phenomena diabetes patients face as revealed in their own voices. Also, understanding of and interest in the subjective experiences of diabetes patients will inform the development of new intervention methods.
