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. Profile Reports
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.
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.
Profile Reports present scores graphically and numerically to summarize the results of each administration. Interpretive Reports
Interpretive Reports include the same information as Profile Reports, along with narrative descriptions of the scales and scores to aid in the interpretation process. For more information on the ADS click here
