Özet:

With a more systematic approach to the functions of the nursing profession, the use of theory/thesis and model is important to reflect its scientific knowledge in nursing research. The purpose of this research is to identify the theory/thesis and models used in the doctoral theses in the field of nursing in Turkey and to bring awareness to nurses doing research. In this investigation planned to identify, the theses were reached by scanning the database of the Turkish Higher Education Institute (YÖK) "National Thesis Center". All the theses in the field of nursing PhD program between 1977-2020 were scaned using the words "model, theory, theory, nursing" by limitation. 215 doctoral theses registered in the database have been achieved and these theses have been evaluated according to the code list prepared by the researchers. 204 theses, numbers and percentages that meet the inclusion criteria were studied using. There are 1819 doctoral theses in the field of nursing in Turkey without a date limit registered in the National Thesis Center. The first thesis prepared using theory/thesis and model in our country was published in 1993 and this doctoral thesis found that the "Orem Self-Care Model" was used. Because the use of theory/thesis and model in the doctoral theses began in 1993, the theses made before this date were left out of scope and all the remaining theses were studied. 11 percent of these. In 2 theory/thesis and model are used. The most frequently used theory/thesis and models were the Roy Adaptation Model(10.8%) and the Pender Health Development Model(10.3) and the Health Faith Model(8.8). In the doctoral thesis of nursing, the theory/thesis and model use rates are determined to be low, and the increase in this rate is very important for the development of nursing science. Research is recommended to be conducted to reflect theoretical approaches to the application.
