The CCI is a 250 item, self-report, psychological and neuropsychological inventory based on the current Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR). Designed for the assessment of correctional inmates and juvenile offenders (15 years and older). The CCI was created (a) to be a cost-effective measure of psychological problems, (b) to be a DSM-IV-TR aligned measure of Axis I clinical syndromes and Axis II personality disorders, (c) to measure neuropsychological symptoms such as memory problems, inattention, language dysfunction, and neurosomatic problems, and neuropsychological syndromes such as neurocognitive disorder, adult ADHD, and executive function deficits of the frontal lobes, and (d) to allow the differential diagnosis of those inmates who have clinically diagnosable syndromes from those who do not. Each of the 250 items is answered on a 4-point Likert-type scale ranging from 1 (strongly false), 2 (more false than true), 3 (more true than false), to 4 (strongly true). The CCI has been normed on and tested with thousands of criminal offenders. Another unique feature of the CCI is that it has a reliable and valid significant-other form.
