Questionnaire Analysis

The Buss–Perry Aggression Questionnaire (AGQ) is a widely used psychological tool designed to measure aggression levels in individuals. Developed by Dr. Arnold Buss and Robert Perry in the 1960s, the AGQ is a self-report questionnaire that evaluates aggressive tendencies in individuals.

Calibration

The AGQ consists of 29 items, each rated on a 5-point Likert scale ranging from: “Not at all” to “Very much”. It includes three subscales: Physical Aggression, Verbal Aggression, Anger.

Objective

The AGQ is widely used for assessing aggression in both adults and children, across clinical and non-clinical populations. It has been validated as a reliable measure of aggression across genders and cultures.

Statistical Analysis

Each subscale of the AGQ measures a different aspect of aggression: Physical Aggression Subscale. Evaluates propensity for physical aggression, such as: Hitting, pushing, or throwing objects. Verbal Aggression Subscale. Assesses tendency towards verbal aggression, including: Name-calling or making threats. Anger Subscale. Measures anger intensity and how individuals: Experience and regulate anger.

Validity and Reliability

The AGQ has demonstrated high reliability and validity in measuring aggression. It has been widely used in studies across various populations. The questionnaire is also useful for tracking changes in aggression over time, making it valuable for longitudinal research and clinical applications.
