Summary
The Nurses Professional Values Scale--Revised (NPVS-R) is a reliable tool for measuring nurses
Area of Science:
- Nursing
- Healthcare Ethics
- Psychometrics
Background:
- The American Nurses Association Code of Ethics for Nurses serves as a foundation for professional nursing values.
- Measuring nurses' professional values is crucial for professional development and ethical practice.
Purpose of the Study:
- To evaluate the psychometric properties of the Nurses Professional Values Scale--Revised (NPVS-R).
- To assess the reliability and validity of the NPVS-R in a diverse nursing population.
Main Methods:
- A random sample of 782 baccalaureate and master's students and practicing nurses completed the 26-item NPVS-R.
- Exploratory and confirmatory factor analysis were employed to analyze the data.
- Internal consistency reliability and construct validity were assessed.
Main Results:
- Factor analysis yielded a five-factor solution (Caring, Activism, Trust, Professionalism, Justice) explaining 56.7% of the variance.
- Internal consistency reliability was supported with alpha coefficients ranging from .70 to .85 for factors and .92 for the total scale.
- Construct validity was supported by factor loadings ranging from .46 to .79.
Conclusions:
- The NPVS-R demonstrates strong psychometric properties, including reliability and validity.
- The NPVS-R is a sound instrument for measuring professional values among nurses.
- This scale can enhance professional socialization and ethical awareness in nursing.

Professional Values
Nurses are responsible for caring for patients during birth, death, illness, and healing. Professional values guide the decisions and actions that nurses make in their careers. If nurses know the decisions and actions to take, providing patients with exceptional care is possible.
The values that are the foundation of the nursing profession are altruism, autonomy, human dignity, and social justice.
First, altruism refers to the concern for the welfare and well-being of others without personal...

Nursing 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.

The Professional Nurse
Professional nurses are not limited to bedside care and are taking roles of greater responsibility. A nurse should have a knowledge-based practice, including personal, theoretical, procedural, cultural, and reflexive knowledge. Additionally, nurses must be competent in cognitive, technical, interpersonal, and ethical/legal skills. Some of the best attributes of successful nurses include the following:
Communication skills: These are critical characteristics, especially speaking and listening.
Communication skills: These are critical characteristics, especially speaking and listening.
Nursing Code of Ethics
The Nursing Code of Ethics sets the ethical benchmark for the profession, and guides nurses in ethical analysis and decision making at the societal, organizational, and clinical levels. The code encompasses showing compassion and respect for the patient, their families, and communities in all circumstances while committing to providing patient-centered care. In addition, the code states that nurses must advocate for the patient by defending a cause or recommendation to protect their rights,...
Self-Report Tests of Personality
Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.
Data Validation
Data validation is an essential part of a comprehensive assessment. Validation is confirming or verifying and opening the door to gathering more assessment data as it clarifies vague or unclear data. The process of checking and verifying the collected information is called data validation. The primary purpose of data validation is to ensure data is as free from error, bias, and misinterpretation as possible.
