Eating and Weight Disorders : EWD
|February 3, 2020
Summary
This study validates the 8-item Eating Self-Efficacy Scale Brief Scale (ESEBS) for assessing confidence in managing eating behaviors during social and emotional challenges. The ESEBS is a reliable tool for understanding eating self-efficacy in diverse situations.
Area of Science:
- Psychology
- Behavioral Science
- Health Psychology
Background:
- Eating self-efficacy (ESE) is crucial for self-regulating eating behaviors.
- Existing ESE scales often focus narrowly on weight management or dieting.
- Social and emotional situations present unique challenges to eating self-regulation.
Purpose of the Study:
- To validate a new, brief scale assessing eating self-efficacy (ESEBS) specifically for social and emotional situations.
- To provide a reliable instrument for measuring confidence in managing excessive food intake under pressure.
- To address the gap in ESE assessment tools for non-dieting contexts.
Main Methods:
- Two studies were conducted involving volunteer participants.
- Study 1 used exploratory factor analysis (EFA) on a 25-item scale with 412 females to select items.
- Study 2 used confirmatory factor analysis (CFA) with 410 adults to confirm the scale's psychometric properties and measurement invariance across gender.
Main Results:
- EFA revealed a bifactorial structure, leading to an 8-item scale (ESEBS).
- CFA confirmed the good fit of the bifactorial model, explaining 63% of the variance.
- The ESEBS demonstrated strong internal consistency (Social α=0.786, Emotional α=0.820) and concurrent validity with eating disorder and emotional eating measures.
Conclusions:
- The 8-item ESEBS is a valid and reliable instrument for assessing eating self-efficacy in social and emotional contexts.
- The scale shows potential for use in both clinical and non-clinical research and interventions.
- Future research should explore the ESEBS's application in diverse populations and therapeutic settings.

01:24Sources of Self-Esteem II: Performance Feedback
151
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:...

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.

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.

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...

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
