The Anger Parameters Scale (APS) is a 30-item self-report questionnaire designed to assess anger much like a signal with spatio-temporal properties. These properties correspond to five APS subscales: frequency, duration, intensity, latency, and threshold. In this psychometric study, 311 young adult students completed the APS. Confirmatory factor analysis supported the theoretically-postulated five-factor structure and a second-order factor underpinning the five dimensions. Composite reliability estimates exceeded the conventional .70 cutoff for reliability, thus providing evidence of internal consistency in the factor structure of the APS. In deconstructing anger, the instrument allows signal properties of an individual’s anger to be measured separately and also plotted as a profile for configural analysis. This allows particular aspects of anger dysfunction to be identified. in emerging adults. The specificity thus obtained can help corroborate clinical diagnoses (e.g., Intermittent Explosive Disorder) that are distinctive in terms of intensity, duration, frequency, and other parameters.
