Summary
A new scale measures oncology nurses' exercise beliefs in women with breast cancer. The Nurses' Exercise Beliefs scale demonstrates validity and reliability for assessing benefits and barriers to exercise.
Area of Science:
- Nursing
- Oncology
- Exercise Science
Background:
- No existing instrument measures oncology nurses' beliefs regarding exercise for breast cancer patients with cancer-related fatigue.
- Cancer-related fatigue is a significant issue for women undergoing breast cancer treatment.
Purpose of the Study:
- To psychometrically evaluate the Nurses' Exercise Beliefs scale.
- To develop a reliable and valid tool for assessing oncology nurses' perspectives on exercise interventions.
Main Methods:
- Scale items were generated from a literature review.
- Content validity was established through an expert panel review.
- The scale was administered to 387 registered nurses for psychometric analysis.
Main Results:
- The scale achieved a content validity index (S-CVI) of .85.
- A two-factor solution explained 50.4% of the variance, supporting construct validity.
- Factors identified were exercise benefits beliefs (α = .94) and exercise barriers beliefs (α = .81).
Conclusions:
- The Nurses' Exercise Beliefs scale subscales are valid and reliable.
- This tool can inform the development of effective exercise interventions for breast cancer patients.

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.

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.

Introduction
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
