Summary
Nurses
Area of Science:
- Nursing
- Healthcare Quality Improvement
- Evidence-Based Practice
Background:
- Limited research exists on nurses' confidence in implementing evidence-based practice (EBP) strategies.
- Self-efficacy in EBP implementation is crucial for accelerating evidence uptake and enhancing healthcare quality.
- Bandura's self-efficacy theory provides the framework for understanding confidence in EBP implementation.
Purpose of the Study:
- To develop and validate the Implementation Self-efficacy for EBP (ISE4EBP) scale.
- To evaluate the psychometric properties of the ISE4EBP scale.
- To measure nurses' self-efficacy in utilizing EBP implementation strategies.
Main Methods:
- Developed a 29-item scale, the ISE4EBP scale.
- Assessed content validity using the content validity index.
- Evaluated internal consistency reliability using Cronbach's alpha.
- Determined construct validity by examining associations with organizational readiness for EBP.
Main Results:
- The ISE4EBP scale demonstrated adequate content validity.
- The scale exhibited excellent internal consistency reliability (Cronbach's alpha = 0.987).
- Construct validity was supported by significant associations with organizational readiness for EBP.
Conclusions:
- The ISE4EBP scale is a psychometrically sound measure of nurses' self-efficacy in EBP implementation strategies.
- This scale can identify areas for professional development to enhance nurses' confidence.
- Building implementation confidence can accelerate the adoption of evidence into practice, improving patient care quality.

01:22Self-Report Tests of Personality
675
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.

01:24Sources of Self-Esteem II: Performance Feedback
141
Self-esteem is intricately tied to our perception of competence and our ability to exert control over our lives. One of the primary sources of this perception is performance feedback — the ongoing evaluation of our actions in terms of success and failure. According to Franks and Marolla (1976), people derive self-worth from experiencing themselves as causal agents, capable of achieving goals and overcoming obstacles. This process nurtures a critical component of self-esteem:...

01:29Self-Evaluation Maintenance Model
201
The Self-Evaluation Maintenance (SEM) model offers a psychological framework to understand how individuals’ self-esteem is influenced by the achievements of others, particularly those with whom they share close personal bonds. The SEM model operates when personal rather than social identity guides individuals. Central to this model is the notion that individuals have an inherent desire to preserve a favorable self-image, which is continuously shaped by interpersonal comparisons and...

Self-esteem, a core aspect of psychological well-being, reflects an individual's positive and negative self-evaluation in terms of worth, competence, and overall value. It is both a stable trait and a dynamic process, influenced by experiences and social interactions across the lifespan. While global self-esteem offers a general assessment, research highlights that self-esteem is multidimensional and varies across specific life domains.Domain-Specific Self-EsteemResearchers have delineated...

Self-esteem, a crucial component of psychological development, is significantly shaped by familial experiences. The early parent-child relationship serves as a foundational influence on a child's self-concept, with long-lasting effects extending into adolescence and adulthood.Parental Behaviors and Early Self-Esteem FormationEmpirical studies have identified four principal parental behaviors that foster healthy self-esteem in children. These include expressions of acceptance, affection, and...
