Summary
This study translated the Violent Ideations Scale (VIS) into European Spanish (VIS-ES). The VIS-ES is a reliable and valid tool for measuring violent thoughts in Spanish-speaking populations.
Area of Science:
- Psychology
- Psychometrics
Background:
- Violent ideations (VIs) are linked to aggression and violence.
- No validated Spanish-language tool currently exists to measure VIs.
Purpose of the Study:
- Translate the Violent Ideations Scale (VIS) into European Spanish.
- Evaluate the psychometric properties of the translated scale (VIS-ES).
Main Methods:
- Convenience sample of 752 Spanish speakers (ages 18-75).
- Assessed dimensionality, gender measurement invariance, concurrent validity, and reliability.
- Collected initial evidence of external validity.
Main Results:
- Confirmed the unidimensionality of the VIS-ES.
- Demonstrated measurement invariance across genders.
- Found high reliability and significant correlations with aggressive behavior.
Conclusions:
- The VIS-ES is a psychometrically sound instrument.
- The VIS-ES is suitable for use in non-clinical Spanish-speaking samples.
- Provides a valuable tool for aggression research in Spanish.

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.

Hostile aggression is motivated by feelings of anger with intent to cause pain; a fight in a bar with a stranger is an example of hostile aggression. In contrast, instrumental aggression is motivated by achieving a goal and does not necessarily involve intent to cause pain (Berkowitz, 1993); a contract killer who murders for...

Personality disorders represent enduring cognition, affect, and behavior patterns that significantly deviate from societal norms. These maladaptive traits often lead to difficulties in various domains, including interpersonal relationships, occupational settings, and overall psychological well-being. Paranoid personality disorder and schizoid personality disorder are two distinct conditions marked by odd or eccentric behavior.
