The Conners' Continuous Performance Test II Version 5 for Windows (CPT II V.5) is widely used with psychiatric and general medical patients to assess attention disorders and neurological functioning.
When used with the Conners' Rating Scales™ - Revised (CRS-R), it adds a task-orientated component to support parent and teacher behaviour ratings.
It can also be used with offenders, where there is a higher than average rate of ADHD. To complete the CPT II V.5, respondents react to target letters on the screen.
The unique Conners' paradigm still forms the basis of the programme.
This programme was standardised with a clinical sample of 378 diagnosed ADHD cases and 223 adult individuals to have some typ of neuropsychological impairment.
An assortment of additional clinical cases (anxiety problems, conduct problems, depression, etc) were included. The non-clinical sample included 1,920 individuals.
