Background/Description

The Multidimensional Anger Inventory (MAI) is a tool developed by Dr. Judith M. Siegel to assess different dimensions of anger, including frequency, duration, intensity, and expression. The MAI is a 30-item multidimensional scale of anger and hostility that measures the frequency, duration, and mode of anger (anger in and anger out), guilt, hostile outlook, and more.

The MAI was designed to be sensitive to the multidimensional nature of the anger construct and to include scales reflective of the following dimensions of anger: frequency, duration, magnitude, mode of expression, and direction of expression. The MAI is used to test an individual’s susceptibility to anger and map their experience of anger along multiple empirical dimensions.

The MAI has been shown to have good psychometric properties and has been used in various studies to assess the relationship between anger and health outcomes, particularly cardiovascular health. Factor analyses of the MAI within two samples showed that the frequency, duration, and magnitude dimensions clustered together to form an anger-arousal factor that accounted for 64% and 71% of the variance in the two samples, respectively. The MAI is available online for free, such as the one offered by Practical Pie. The MAI is a useful tool for clinicians and researchers to assess different dimensions of anger and hostility and to develop interventions to manage anger effectively.

Administration, Scoring and Interpretation

The Multidimensional Anger Inventory (MAI) is a self-report questionnaire that consists of 30 items designed to assess different dimensions of anger, including frequency, duration, intensity, and expression. The MAI is administered by asking individuals to rate how often they experience different feelings and behaviors related to anger on a 5-point Likert scale, ranging from “never” to “always”.

The MAI is scored by summing the responses to each item, with higher scores indicating greater levels of anger and hostility. The MAI has been shown to have good reliability and validity in research and clinical settings. The MAI is a widely used tool in research and clinical settings to assess anger and hostility.

Reliability and Validity

The Multidimensional Anger Inventory (MAI) has been found to be a reliable and valid measure of anger and hostility in various populations. The MAI has been shown to have good internal consistency, test-retest reliability, and construct validity.

Factor analyses of the MAI have shown that the frequency, duration, and magnitude dimensions clustered together to form an anger-arousal factor, while the anger-in and anger-out dimensions formed separate factors. The MAI has been used in research and clinical settings to assess anger and hostility in various populations, including male inmates and college students.
