Instrument Description

The Instrument for Reactive and Proactive Aggression (IRPA-6) is a psychometric tool designed to measure two primary forms of aggression: reactive and proactive aggression. It consists of 6 questions that assess an individual’s responses to provocations and situations, as well as tendencies toward aggressive behavior that arise from strategic planning or goal pursuit.

Data Analysis and Usage

Data analysis from the IRPA-6 focuses on identifying and understanding aggression patterns. Statistical methods, such as factor analysis and Analysis of Variance (ANOVA), are used to identify relationships between different forms of aggression and other psychological or social variables. This data helps in developing targeted intervention and support programs.

Objective

The primary objective of the IRPA-6 is to differentiate and evaluate the various forms of aggression that may manifest in different situations. The tool helps to understand the causes behind aggressive behavior, whether it results from self-defense (reactive) or from a strategic approach (proactive). This understanding aids in developing intervention and support strategies for effective aggression management.

Calibration

The IRPA-6 is scored using a Likert scale, where participants rate each statement from “Strongly Disagree” to “Strongly Agree.” Responses are categorized into two main types: reactive aggression and proactive aggression. Scores are aggregated to provide an overall profile of the individual’s levels and types of aggression.
