Self-Schemas02:16

Self-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.
Self-Evaluation Maintenance Model01:29

Self-Evaluation Maintenance Model

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-Report Tests of Personality01:22

Self-Report Tests of Personality

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.
Confirmation Biases01:31

Confirmation Biases

The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?
Assessment of the Gastrointestinal System II: Health Perception Pattern01:29

Assessment 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:
Personality Theory by Eysenck and Eysenck01:29

Personality Theory by Eysenck and Eysenck

Hans and Sybil Eysenck developed a widely recognized theory of personality, which emphasizes the role of temperament and genetically based differences in shaping individual traits. Their theory posits that biological factors primarily determine personality and can be understood through two main dimensions: extroversion/introversion and neuroticism/stability.
In the extroversion/introversion dimension, highly extroverted people are sociable, outgoing, and easily connect with others. In contrast,...

Area of Science:

  • Psychological assessment
  • Adolescent psychology
  • Eating disorder research

Background:

  • Previous studies failed to replicate the Eating Attitudes Test (EAT-26) factor structure in adolescent community samples.
  • Replicating the EAT-26 structure is crucial for accurate eating disorder assessment in adolescents.

Purpose of the Study:

  • To revisit and validate the factor structure of the Eating Attitudes Test (EAT) in mixed-gender adolescent community samples.
  • To develop a reliable and valid short version of the EAT for adolescent populations.

Main Methods:

  • Utilized exploratory structural equation modeling (ESEM) and confirmatory factor analysis (CFA) on a large adolescent sample (n=2178).
  • Tested the factor structure, reliability, and measurement invariance (gender, age, ethnicity, weight) of the proposed EAT-18 model.
  • Assessed convergent validity with the Eating Disorder Inventory and other psychological measures.

Main Results:

  • A six-factor model of the Eating Attitudes Test with 18 items (EAT-18) demonstrated satisfactory fit and reliability.
  • The EAT-18 model showed invariance across gender, age, ethnicity, and weight categories in adolescents.
  • Convergent validity was supported by correlations with the Eating Disorder Inventory and measures of self-esteem and appearance anxiety.

Conclusions:

  • The 18-item Eating Attitudes Test (EAT-18) provides a robust and valid measure for assessing eating attitudes in diverse adolescent populations.
  • The EAT-18's invariance across demographic factors enhances its utility in clinical and research settings.
  • This revised instrument is a valuable tool for early identification and intervention in adolescent eating disorders.
