Summary
This review mapped eating self-efficacy scales, finding them useful but lacking content validity. Future research should improve scale development for better clinical application.
Area of Science:
- Psychology
- Nutrition Science
- Health Services Research
Background:
- Eating self-efficacy scales are crucial for understanding and intervening in eating behaviors.
- A comprehensive understanding of existing scales' psychometric properties and applications is needed.
Purpose of the Study:
- To map and analyze eating self-efficacy scales, assessing their characteristics, use, psychometric quality, and literature gaps.
- To provide a synthesis of available instruments for researchers and clinicians.
Main Methods:
- A scoping review following PRISMA-ScR and Joanna Briggs Institute methodology.
- Searches across multiple databases (EMBASE, PubMed, PsycInfo, Web of Science, LILACS, Scopus) without language or time restrictions.
- Inclusion of studies validating or cross-culturally adapting eating self-efficacy scales; data extraction and appraisal using PROMs and COSMIN criteria.
Main Results:
- Forty-six studies were included, detailing 28 original and 19 adapted scales.
- High internal consistency (α/Ω = 0.73-0.97) and feasibility for self-administration were generally observed.
- Content validity was the weakest aspect, with only 2 scales meeting COSMIN criteria; interpretability was also limited.
Conclusions:
- Eating self-efficacy scales are valuable for assessing eating behaviors and guiding interventions.
- Significant methodological gaps exist, particularly in content validity, hindering optimal clinical utility.
- Future scale development requires more robust procedures, clear conceptual grounding, and systematic evaluation.

02:16Self-Schemas
In general, a schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.
01:29Self-Efficacy
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...
01:24Sources of Self-Esteem II: Performance Feedback
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: self-efficacy,...
01:29Assessment of the Gastrointestinal System II: Health Perception Pattern
Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health Perception Patterns
Health perception patterns offer valuable insights into a patient's lifestyle habits and how they may impact their GI health. These patterns include:

01:25Self-Regulation
Self-regulation, also known as self-control, encompasses a range of cognitive and behavioral processes that allow individuals to adjust their internal states and outward actions to align with socially acceptable norms and long-term goals. It plays a fundamental role in adaptive functioning, from resisting impulsive behaviors to persisting through challenging tasks. While its benefits are widely recognized, self-regulation is not limitless. Muraven and Baumeister's theory posits that...
02:45Self-Discrepancy Theory
One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.
