Scale Description

The Modified Aggression Scale (MAS-22) is a psychometric tool designed to measure various aspects of aggression in individuals. It consists of 22 items that examine behaviors and feelings related to aggression, such as aggression towards others, self-destructive aggression, and internalized aggression.

Data Analysis and Usage

Data collected through the MAS-22 are analyzed to identify patterns and trends in aggression. Analyses may include statistical methods such as Analysis of Variance (ANOVA) to identify differences between groups or multiple regression analysis to explore relationships between aggression and other psychological or social variables.

Objective

The primary objective of the MAS-22 is to assess the frequency and intensity of an individual’s aggressive behaviors and feelings. The tool is used in research settings to analyze aggression levels across different populations, understand the factors influencing aggression, and design interventions to address aggressive behavior.

Calibration

The MAS-22 is scored using a five-point Likert scale, where participants rate each statement from “Strongly Disagree” to “Strongly Agree.” The scores are aggregated to provide an overall profile of an individual’s aggression levels. The scale can be analyzed overall or in subcategories to identify specific types of aggression.
