Summary
A new scale reliably measures the teaching experiences of nurse instructors guiding newly graduated nurses (NGNs). This tool helps managers understand and support NGNs
Area of Science:
- Nursing Education
- Healthcare Professional Development
- Medical Education Research
Background:
- Guideline-based education for newly graduated nurses (NGNs) relies on potentially inexperienced nurse instructors.
- Inexperienced instructors face increased burden and anxiety when teaching NGNs.
- A validated tool is needed to assess nurse instructors' teaching experiences.
Purpose of the Study:
- To develop and validate a scale measuring the teaching experiences of nurses instructing NGNs.
- To assess the reliability and validity of a 72-item scale draft.
Main Methods:
- Cross-sectional survey of 157 experienced nurses in Japanese hospitals (400+ beds).
- Exploratory factor analysis (EFA) and factor-item consistency analysis were performed.
- Cronbach's alpha was used to assess reliability.
Main Results:
- EFA identified 27 items across five factors: cooperation, support, positive teaching, teaching struggles, and achievement-based teaching.
- Cronbach's alpha coefficients ranged from .849 to .923 per factor, with an overall alpha of .924.
- Factor-item consistency indicated good model fit (CFI=.871, RMSEA=.081).
Conclusions:
- The developed scale is reliable and valid for measuring nurse instructors' experiences teaching NGNs.
- This scale can inform managers about teaching experiences, enabling tailored support for NGNs.
- Findings support individualized learning experiences and professional development for nurse instructors.

01:15Nursing Evaluation

The evaluation stage signals the end of the nursing process. The nurse gathers evaluative data to assess whether or not the patient has attained the expected results. Whereas the nurse collects data in the nursing assessment to identify the patient's health concerns, the evaluation stage data determines if the indicated health issues are resolved. Evaluative data collection includes two sections: the data acquired to evaluate patient outcomes and the time criteria for data collection.

Evaluation of the teaching process enables the nurse to determine if the patient's learning needs were met and if training was effective. If the expected outcomes are not met, the care plan is revised, and additional education or reinforcement is provided. Nurses can ask questions after the session or obtain feedback to assess the patient's understanding of the topic.
Nurses can use several methods to evaluate patient outcomes. For example, oral questions can assess cognitive learning,...

The nursing process provides a clinical decision-making framework for patients and families to establish and implement a personalized care plan. Since part of the nurse's duties is to teach patients, the steps of the nursing process are the most effective way to approach instruction. The nursing process and the teaching-learning process are inextricably linked.

2.2K
Planning for learning involves the development of a teaching plan. Teaching plans are similar to nursing care plans—both follow the steps of the nursing process. Planning in the teaching process involves setting goals and outcomes. Here, goals identify what a patient needs to achieve to understand a healthcare topic better, whereas the outcomes are the action to be performed by the patient to achieve the goal within a timeframe. For example, if the goal is to educate the patient about...

4.2K
Nursing diagnoses represent a problem validated by major defining characteristics. There are four categories of nursing diagnoses: problem-focused, risk, health promotion or wellness, and syndrome. The anatomy of a nursing diagnosis includes three components: problem statement or diagnostic label, defining characteristics, and related factors.

01:29Reliability and Validity
14.2K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.
