Summary
This study developed a new scale to measure aggressive beliefs and attitudes in adults. The validated scale reliably predicts aggressive behaviors and biases.
Area of Science:
- Psychology
- Social Psychology
- Forensic Psychology
Background:
- Aggressive beliefs and attitudes are key factors in understanding aggressive behaviors.
- Existing measures may not fully capture the nuances of explicit aggressive cognitions.
Purpose of the Study:
- To develop and validate a new self-report measure assessing explicit aggressive beliefs and attitudes.
- To examine the psychometric properties and predictive validity of the new scale.
Main Methods:
- Development and validation of a new self-report scale.
- Utilized 7 samples with a total of 3,533 adult participants.
- Assessed hierarchical factor structure, reliability, and validity (convergent, discriminant, criterion-related).
Main Results:
- The new scale demonstrated good reliability and a hierarchical 6-factor structure.
- The scale showed convergent and discriminant validity.
- Criterion-related validity confirmed incremental prediction of aggression-related behaviors over other factors.
Conclusions:
- The developed scale is a reliable and valid instrument for assessing explicit aggressive beliefs and attitudes in adults.
- This measure offers valuable insights into aggressive biases and can predict aggressive behaviors.

01:54Attitudes
Attitude is our evaluation of a person, an idea, or an object. We have attitudes for many things ranging from products that we might pick up in the supermarket to people around the world to political policies. Typically, attitudes are favorable or unfavorable: positive or negative (Eagly & Chaiken, 1993). And, they have three components: an affective component (feelings), a behavioral component (the effect of the attitude on behavior), and a cognitive component (belief and knowledge;...
02:55Stereotypes, Prejudice, and Discrimination
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who are...
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...
01:29Self-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...
03:00Self-Evaluation: Self-Enhancement and Self-Verification
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...
01:24Rational Emotive Behavior Therapy
Cognitive-behavioral therapies (CBTs) are grounded in the belief that our thoughts profoundly influence our emotions and actions. Advocates of CBT emphasize three core assumptions: first, that cognitions are identifiable and measurable; second, that they are central to psychological functioning; and third, that irrational or maladaptive beliefs can be replaced with rational and adaptive ones. This transformative approach to therapy has paved the way for specific models such as Albert Ellis's...
