The study was conducted as a randomized controlled experimental study in order to determine the effect of hybrid simulation training on gaining the intramuscular injection skills of nursing students. The sample of the study consisted of 126 students (63 study groups, 63 control groups) enrolled in Nursing Principles Course at Pamukkale University Faculty of Health Sciences in 2018-2019 academic year. In the study, the study group performed hybrid simulation (standard patient+Digital half hip model simulator) and the control group performed simulation with low reality simulation method (hip/intramuscular model). Study data were collected using Student Identification Form, Intramuscular Injection Achievement Test, Intramuscular Injection Application Skill Assessment Form, Two Column Writing Reflective Thinking Strategies and Scale of Student Satisfaction and Self-confidence in Learning.

Nursing students need to be proficient in nursing knowledge and skills before entering a health care environment in order to provide safe care to patients. One of the important and difficult to accomplish skills that nursing students must learn is the ability to administer intramuscular injections. In order to avoid complications due to IM injection application, it is necessary to comply with surgical asepsia, to know the method of application correctly and to have psychomotor skills. Therefore, nursing students are expected to graduate with knowledge and skills related to IM injection application during their education. Basic plastic mannequins without advanced technology, mannequins or models with low technological features that present the selected anatomical parts of the human body can also be used in standard patient and hybrid simulation. Hybrid simulation applications contribute to learners ' ability to develop psychomotor skills in a safe and realistic environment, as well as problem solving, critical thinking and decision making. Furthermore, hybrid simulations have become an ethical requirement to improve students ' skills without causing any potential harm to actual patients. In this study, the effectiveness of HS method will be evaluated to gain IM injection skills in nursing students. It will be ensured that the students ' knowledge and skills will be sufficient by increasing their desire to learn about IM injection, where they experience intense fear and anxiety before going to the clinic.

Inclusion Criteria:

• Students who have not received IM injection skills training before,
• who have no clinical experience,
• who have accepted to participate in the research

Exclusion Criteria:

• Students who have received IM injection skills training before,
• who have clinical experience,

Study results will be announced in a publication

Findings can be shared after the study has been published.

The sociodemographic characteristics of the participants, the test findings including the answers to the research questions and statistical analyzes will be shared.
