The present study evaluates the opinions of nurses regarding the use of nursing theories and models. Materials and Methods: This qualitative study involved a total of 36 nurses hemşire (Master’s degrees students n:12, doctoral students n:12, nurse n:12). The study data was collected through focus group interviews using a Semi-Structured Interview Form, and an audio recording of the interviews was also made. The data obtained from the interviews was analyzed thematically. Results: There were three main themes designated in this research: the pros and cons of working with nursing theories and models; factors hindering working with theories/models; and suggestions for increasing the use of such models. These main themes were structured so as to encompass the application, research, management and education fields. Conclusion: The respondents suggested that the number of nurses with competencies in nursing theories/models must be increased; that appropriate theories and models must be developed on the basis of care requirements; that these subjects must be included in the undergraduate program; and that culture-specific theories and models must be developed that can be reflected on care.
