Summary
This study introduces a new, reliable, and valid measure for negative core beliefs about the self and others. This tool aids in understanding psychopathology within A. T. Beck
Area of Science:
- Psychology
- Cognitive Behavioral Therapy
- Psychopathology Research
Background:
- Core beliefs are central to A. T. Beck's cognitive theory.
- Limited empirical data exists on core belief psychometric properties and their link to psychopathology.
Purpose of the Study:
- To develop and validate a new measure for negative core beliefs about the self (nCB-S) and others (nCB-O).
- To provide initial evidence for the reliability and validity of this novel instrument.
Main Methods:
- Development of a new core beliefs measurement scale.
- Internal consistency and test-retest reliability assessments.
- Factor analysis to examine the structure of nCB-S and nCB-O.
- Correlational analysis with childhood experiences, attachment styles, anxiety, and depression.
Main Results:
- The new measure demonstrated adequate internal consistency and test-retest reliability.
- Factor analysis supported nCB-S and nCB-O as distinct dimensions.
- Preliminary evidence suggests nCB-S can be further categorized into helplessness, unlovability, and worthlessness.
- Scale scores positively correlated with negative childhood experiences, insecure attachment, anxiety, and depression.
Conclusions:
- Core beliefs can be reliably and validly measured.
- The developed instrument offers a tool for future research validating A. T. Beck's cognitive theory.
- Findings support the role of core beliefs in understanding anxiety and depression.

01:22Self-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.

Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...

01:29Reliability and Validity
13.6K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

183
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...

Person perception is influenced by both external behaviors and the observer’s internal characteristics, including personality traits. Individuals with dark personality traits, comprising psychopathy, Machiavellianism, and narcissism — collectively known as the dark triad – exhibit manipulative and exploitative tendencies in social contexts. These traits affect how they perceive others and how they are perceived.The Role of Dark Personality Traits in Person PerceptionBlack et...

01:23Implicit Personality Theories

Implicit personality theory explains how individuals make assumptions about the relationships between personality traits, behaviors, and character types. When people learn that someone possesses a particular trait, they tend to infer the presence of other related characteristics, forming a cohesive impression. This cognitive shortcut plays a crucial role in social interactions and interpersonal judgments.Central Traits and Their InfluenceSolomon Asch's seminal 1946 study highlighted the power...
