Summary
This study validates an advanced practice nursing tool using factor analysis. The findings support the tool's five domains, aiding in defining advanced practice nurse roles and services.
Area of Science:
- Nursing Practice
- Healthcare Workforce Development
Background:
- Limited research defines advanced practice nursing roles and domains.
- A valid tool is needed to clarify service parameters for advanced practice nurses.
- This study is part of a larger Australian initiative to assign advanced practice roles.
Purpose of the Study:
- To determine the construct validity of a modified advanced practice role delineation tool.
- To examine the factor structure of the tool using exploratory factor analysis.
Main Methods:
- A postal survey was distributed to a random sample of Registered Nurses and midwives in Queensland, Australia.
- The modified Advanced Practice Role Delineation tool was used in the survey.
- Exploratory factor analysis (principal axis factoring) and Cronbach's alpha were employed.
Main Results:
- 658 responses were received, yielding a 42% response rate.
- Factor analysis identified five factors for 40 of 41 activities, aligning with the Strong model.
- High reliability was confirmed with an overall Cronbach's alpha of 0.94 and factor alphas ranging from 0.83 to 0.95.
Conclusions:
- Exploratory factor analysis confirms the validity of the five domains within the modified advanced practice role delineation tool.
- The findings support the tool's utility in defining advanced practice nursing roles.
- Further research is recommended to explore the tool's application in diverse healthcare settings.

01:21Role-Based Identity
Role-based identities are central to understanding how individuals navigate social environments by adopting distinct self-conceptions aligned with various societal roles. These identities are not fixed traits but are constructed through personal actions and the social feedback individuals receive in context-specific interactions. Each social role, such as student, teacher, or friend, carries a set of expectations and norms that influence how people think, feel, and behave within that...
01:25Role of Communication in the Nursing Process I: Assessment and Diagnosis
The nursing process uses scientific reasoning, problem-solving, and critical thinking to guide nurses in providing patients with appropriate care. This process is a systematic approach to recognize, avoid, and treat current or potential health issues while promoting the patient's well-being.
The nursing process considers the patient's emotional and physical well-being. The process can be repeated or stopped at any point if judged essential. Assessment is the first step in the nursing process.

01:21Interdisciplinary Care: The Health Care Team-I
An interdisciplinary team includes many healthcare professionals working together and utilizing their skills, knowledge, and expertise to provide holistic and quality patient care.
Physicians
The physician's primary responsibility is to diagnose illness and direct the medical or surgical treatment of the condition. The authority to admit patients to a healthcare agency or institution and practice care within that setting is granted to physicians by the healthcare agency or institution itself.

01:25Role of Communication in the Nursing Process II: Planning and Implementation
Several factors are considered while creating a patient's care plan. Motivation is a factor in improving communication, and patients often require encouragement to try different approaches involving significant change. It is essential to involve the patient and family in decisions about the plan of care to determine whether the suggested methods are acceptable. Consider meeting critical comfort and safety needs before introducing new communication methods and techniques. Allow adequate time for...
01:25Formulating and Validating Nursing Diagnosis II
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.
Risk nursing diagnoses represent clinical judgments of an individual, family, or community more vulnerable to developing the health problem than others...

01:25Fundamentals of Nursing Process II
There are several characteristics related to delivering nursing care. One vital characteristic of the nursing process is that it can be used to protect nurses and justify the provided care. Productive use of the nursing process requires the knowledge and skills of nurses to assess and solve issues. Nurses should develop and strengthen their critical thinking skills and evidence-based nursing interventions to improve their skills in formulating nursing care plans. A well-defined approach to...
