[Multidimensional anger scale]

To develop a new and original scale which can measure anger on a multidimensional level.

In the first phase of this study, 2 pilot studies were conducted. The first pilot study was conducted on a sample of 60 individuals to develop an item pool. A second pilot study was conducted with another group of 148 individuals using a 429 item scale that was developed from this item pool. After the item analyses, a 158 item 'Multidimensional Anger Scale' (MAS) was derived for use in the second phase of the study to investigate the psychometric properties of the instrument. In the second phase reliability and validity analyses of this scale with 5 dimensions, Anger symptoms, Anger eliciting situations, Anger related cognitions, Anger reactions and Interpersonal Anger, were conducted on a sample of 756 individuals.

Psychometric analysis of the scale showed that it possessed adequate internal consistency (alpha coefficients between 0,64 and 0,95). The validity of the scale was supported by the expected pattern of relations with other inventories (Brief Symptom Inventory and Guilt and Shame Scale).

Multidimensional Anger Scale, for Turkish culture, may be suggested as a valid and reliable scale to measure anger in different dimensions.
