A pilot test of the CM-GAF among offenders with mental disorders

A pilot test of clinician-rated validity of scores on a Correction Modified-Global Assessment of Functioning (CM-GAF) scale was performed by assessing a random sample of 60 adult male and female offenders at two correctional facilities. Pairs of trained clinicians assessed the offenders with the CM-GAF and GAF instruments. Regression analyses were conducted. Variables included in the analysis were demographic characteristics (age, gender, and race), criminal history (number of incarcerations, violent/non-violent offense, year of current incarceration), number of disciplinary reports (tickets), and Connecticut Department of Corrections (CDOC) risk scores. The model for the CM-GAF yielded one significant predictor variable, Presence of Pending Charges Risk Score (B = -7.25, p = .003), predicting 44.4% of the variance. This finding suggests that higher functioning offenders tend not to have pending charges, which may be a proxy for length of incarceration. Newly admitted offenders are more likely to have pending charges and more likely to exhibit disruptive and disorganized behaviors. Management of mentally ill persons who are incarcerated is facilitated when inter-professional frontline staff can communicate using a common language. Frequent assessment with an instrument that is understandable across disciplines has the potential to improve care, and as few standardized mental health instruments are modified and tested for use in the prison environment. Additional studies, refining scoring across subsamples by age, race, gender, diagnosis, and levels of security, are still needed.
