Sacks, S., Melnick, G., Coen, C. (2007©) Co-Occurring Disorders Screening Instrument for Severe Mental Disorders (CODSI-SMD)
The Co-occurring Disorder Screening Instrument (CODSI) is designed to screen for mental disorder among prison inmates with a history of substance abuse. There are two versions of the CODSI, a 6-item version (CODSI-MD) that screens for any mental disorder (CODSI-MD) and a 3-item version (CODSI-SMD) that screens for severe mental disorder. The CODSI was validated against the Structured Clinical Interview for DSM-IV on a sample of 180 prison inmates entering prison-based substance abuse treatment in four states. The CODSI-MD with a cutoff score of 3 showed a sensitivity score (ability to detect mental disorder when it is present) of 75.1%, specificity (the rejection of mental disorder when it is not present) of 54.1% and an overall accuracy of 69.6%. The CODSI-SMD with a cutoff score of 2 showed a sensitivity score of 50.8%, a specificity score of 91.2% and an overall accuracy of 78.1%. These results were comparable to three other screening instruments, the Modified MINI Screen (MMS; Brandau, Alexander, & Haugland, 2005), the Mental Health Screening Form (MHSF; Carroll, & McGinley, 2000) and the Global Appraisal of Individual Needs Short Screener version 1.0 (GSS; Dennis, Chan, & Funk, 2006).
