A brief screening instrument for emotionally unstable and dissocial personality disorder in male offenders with intellectual disabilities.

The team built a five-minute checklist called the PDCC. Staff who know the client circle simple statements about mood, anger, and rule-breaking.

They tested it with male offenders who have intellectual disability. The goal was to spot two personality styles: emotionally unstable and dissocial.

The PDCC scores lined up with official diagnoses and with records of past violence. High scores meant more hospital stays and more fights.

Reliability was strong — different staff got similar numbers when they rated the same man.

Wilder et al. (2020) also use a quick staff checklist, the PDC-HS, but for fixing employee errors, not client traits. Both tools show that five targeted questions can steer big decisions.

Ditzian et al. (2015) took the PDC-HS into an autism clinic and raised staff performance. Their success backs the PDCC idea: brief ratings plus a clear next step equal real change.

Clarke (2003) and O'Brien (2003) push the DC-LD system for full psychiatric labels in adults with ID. The PDCC does not replace DC-LD; it gives you a fast red flag while DC-LD handles formal diagnosis.

You now have a five-minute screen that any staff member can complete during a shift. Use it to decide who needs a full risk assessment, closer supervision, or specialized treatment track. The checklist costs nothing and predicts violence history, so you can act early instead of waiting for the next incident report.
