Summary
The Mock Code Self-Efficacy Scale effectively measures nursing students’ confidence in mock codes. This validated tool can assess if self-efficacy improves skill transfer to clinical settings.
Area of Science:
- Nursing Education
- Psychometrics
- Healthcare Simulation
Background:
- Cardiopulmonary resuscitation (CPR) is a critical skill in nursing.
- Effective training in CPR scenarios is essential for patient safety.
- Assessing student confidence in emergency procedures is vital.
Purpose of the Study:
- To psychometrically evaluate the Mock Code Self-Efficacy Scale.
- To validate a tool measuring senior baccalaureate nursing students' self-efficacy in mock codes.
- To establish the reliability and validity of a novel self-efficacy assessment instrument.
Main Methods:
- Psychometric analysis of the Mock Code Self-Efficacy Scale.
- Assessment of item characteristics, face validity, content validity, reliability, and dimensionality.
- Data collected from 153 senior nursing students in a critical care course.
Main Results:
- The scale demonstrated multidimensionality with high reliability (0.75–0.87).
- The instrument showed strong content and face validity.
- A ceiling effect was noted, potentially influenced by pre-assessment instructions.
Conclusions:
- The Mock Code Self-Efficacy Scale is a psychometrically sound instrument.
- It can be utilized to evaluate the impact of self-efficacy on skill transfer from mock codes to clinical practice.
- Findings support the use of the scale in nursing education research and practice.

10.0K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

Hydronium and hydroxide ions are present both in pure water and in all aqueous solutions, and their concentrations are inversely proportional as determined by the ion product of water (Kw). The concentrations of these ions in a solution are often critical determinants of the solution’s properties and the chemical behaviors of its other solutes. Two different solutions can differ in their hydronium or hydroxide ion concentrations by a million, billion, or even trillion times. A common means of...

01:29Nursing Code of Ethics
4.6K
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-efficacy is the belief in one's capacity to organize and execute actions necessary to manage prospective situations. This belief significantly influences how individuals approach goals, tasks, and challenges across different domains of life.Psychological and Educational ImpactsIndividuals with strong self-efficacy are more resilient in the face of difficulties. They are more likely to adopt effective problem-solving strategies, persist through obstacles, and regulate emotions such as...

In designing and analyzing filters, resonant circuits, or circuit analysis at large, working with standard element values like 1 ohm, 1 henry, or 1 farad can be convenient before scaling these values to more realistic figures. This approach is widely utilized by not employing realistic element values in numerous examples and problems; it simplifies mastering circuit analysis through convenient component values. The complexity of calculations is thereby reduced, with the understanding that...
