An objective self-report instrument–the Clinical Anger Scale (CAS)–was designed to measure the psychological symptoms presumed to have relevance in the understanding and treatment of clinical anger. Twenty-one sets of statements were prepared for this purpose. In writing these groups of items, the format from one of Beck’s early instruments was used to design the Clinical Anger Scale (Beck et al., 1961; Beck, 1963, 1967). The following symptoms of anger were measured by the CAS items: anger now, anger about the future, anger about failure, anger about things, angry-hostile feelings, annoying others, angry about self, angry misery, wanting to hurt others, shouting at people, irritated now, social interference, decision interference, alienating others, work interference, sleep interference, fatigue, appetite interference, health interference, thinking interference, and sexual interference. Subjects were asked to read each of the 21 groups of statements (4 statements per group) and to select the single statement that best described how they felt (e.g., item 1: A = I do not feel angry, B = I feel angry, C = I am angry most of the time now, and D = I am so angry all the time that I can’t stand it). The four statements in each cluster varied in symptom intensity, with more intense clinical anger being associated with statement “D.” Each cluster of statements was scored on a 4-point Likert scale, with A = 0, B = 1, C = 2, and D = 3. Subjects’ responses on the CAS were summed so that higher scores corresponded to greater clinical anger (21 items; range 0 – 63).
A scoring procedure similar to Beck’s (Beck et al., 1996). is used with the Clinical Anger Scale (CAS)–where a clinical anger score in a particular range is labeled in a manner similar to Beck’s procedure. That is, clinical interpretation of the CAS scores is accomplished through the following interpretive ranges: 0-13 – minimal clinical anger; 14-19 – mild clinical anger; 20-28 – moderate clinical anger; and 29-63 – severe clinical anger.
