ADS™

Profile Reports summarize the results of an individual administration, providing scores for all scales.
Interpretive Reports provide detailed information about scores from a single administration, presented both numerically and graphically. An individual's scores are compared to those in the normative sample and elevations at the scale and subscale level are indicated.

The ADS consists of the original ADS, as well as a shorter version (ADS:S). Both are available in handscored and software format. For the handscored ADS, respondents use Item Booklets and QuikScore^™. Forms to complete the assessment. Responses are recorded and scores are calculated on the QuikScore^™ Form. For the ADS:S, the items are included on the QuikScore^™ Form, so Item Booklets are not necessary. Profile Reports and Interpretive Reports can be instantly generated with the software format of the ADS.

Reliability

Reliability estimates of the ADS indicate strong support for the factor structure of the instrument. Internal consistency reliability is .97 for the full version Total score, and ranges from .70 to .96 for the subscales and higher order factors. The internal consistency reliability of the short version Total score is estimated at .86. Test-retest reliability estimates (based on a 2-week interval) range from .83 to .92 for the various scales of the full and short versions.

Validity

The ADS and ADS:S were both evaluated for test-retest reliability and internal consistency. The instruments were found to have high correlations with other measures of anger, demonstrating their concurrent validity. Discriminative validity was also shown in both instruments’ ability to differentiate between normal and clinical samples.

The ADS and ADS:S normative sample included more than 1,400 people between the ages of 18 and 76 who were recruited through educational and work environments, as well as through the Internet. The clinical sample included aggressive drivers, general outpatients, individuals seeking mental health services for anger problems.
