Buss–Perry Aggression Questionnaire (BPAQ)
The Buss–Perry Aggression Questionnaire (BPAQ) is a self-report instrument developed to assess different dimensions of aggression in individuals. It was introduced by Arnold Buss and Mark Perry in 1992 and remains widely used in psychological research and clinical settings.
The BPAQ measures aggression through four distinct subscales:
- Physical Aggression – assesses tendencies towards physical confrontation or harm.
- Verbal Aggression – measures aggressive communication styles, such as hostility in speech.
- Anger – evaluates emotional responses, focusing on irritability and the experience of anger.
- Hostility – captures feelings of resentment and suspicion, reflecting cognitive aspects of aggression.
The questionnaire consists of 29 items, with responses scored on a five-point Likert scale (ranging from “extremely uncharacteristic of me” to “extremely characteristic of me”). By examining these subscales, the BPAQ offers a comprehensive view of both physical and psychological aspects of aggression, making it useful for assessing aggressive behaviour in various contexts.
Dimensions of Anger Reactions Scale (DAR-5)
The Dimensions of Anger Reactions Scale (DAR-5) is a concise, five-item questionnaire designed to assess an individual’s experience and management of anger. Developed for use in clinical and research settings, the DAR-5 is particularly suited for quickly evaluating anger severity and its impact on daily life, making it ideal for screening purposes.
The DAR-5 focuses on five key dimensions:
- Frequency – how often the person feels anger.
- Intensity – the level of anger experienced.
- Duration – how long the anger tends to last.
- Aggression – the likelihood of aggressive responses or behaviours.
- Interference – how anger impacts relationships, work, or other areas of life.
Each item is rated on a five-point Likert scale, ranging from “None or almost none of the time” to “All or almost all of the time.” Scoring helps identify individuals with heightened anger levels who may benefit from further support or intervention. Its brevity and focus on relevant anger dimensions make the DAR-5 effective for both quick assessments and initial anger screenings in various populations.
Novaco Anger Scale (NAS)
The Novaco Anger Scale (NAS) is a psychological assessment tool designed to evaluate an individual’s experience of anger, particularly in terms of triggers, intensity, and management strategies. Developed by Raymond Novaco in the 1970s, the NAS is widely used in both clinical and research settings to understand anger dynamics, especially in populations prone to anger-related issues.
The NAS assesses anger across three main components:
- Arousal – measures physical and emotional responses when angered.
- Cognition – examines thought patterns and beliefs that may fuel or sustain anger, such as assumptions of hostility or unfairness.
- Behaviour and Control – evaluates anger expression and regulation, including tendencies toward verbal or physical responses and the ability to manage anger.
The questionnaire consists of statements that respondents rate, capturing their experiences with anger-provoking situations. The NAS can also include a Provocation Inventory (PI), which identifies specific situations that trigger anger, such as interpersonal conflict or unfair treatment.
Multidimensional Anger Inventory (MAI)
The Multidimensional Anger Inventory (MAI) is a detailed self-report tool designed to assess various facets of anger, offering a broad view of how individuals experience and respond to anger. Developed by Judith M. Siegel in 1986, the MAI is widely recognised for its thorough approach in evaluating the nuances of anger.
The MAI covers several key dimensions:
- Frequency – assesses how often anger arises.
- Duration – measures how long anger persists once triggered.
- Magnitude – examines the intensity of anger experiences.
- Anger Arousal – considers physical and emotional responses to anger.
- Range of Situations – identifies the types of situations that typically provoke anger.
- Hostile Outlook – explores general tendencies toward hostility or mistrust of others.
The questionnaire uses a Likert scale, allowing individuals to rate how typical each dimension is for them. Its multidimensional approach provides a comprehensive profile of an individual’s anger patterns, making it useful for a wide range of purposes.
