A new generation of scales to measure mental and substance use disorders

The current program of research represents the largest study to apply Item Response Theory to improve the measurement of mental and substance use disorders. A series of new item banks have been developed using a highly systematic procedure for a range of disorders. These item banks precisely and validly target the full range of disorder severity experienced by community and clinical populations. From these item banks a series of data-driven static short forms and adaptive tests have been developed to efficiently measure disorders and screen for a diagnosis without compromising on precision. These short scales are valid with respect to existing scales used widely in the literature. Finally, these item banks were used to statistically equate a range of self-report scales to facilitate data comparisons and data pooling. Currently, eight scales for measuring psychological distress have been equated as well as multiple scales for measuring social anxiety disorder. These new instruments are freely available to researchers and clinicians.
