Introduction
The original 22-item Hare Psychopathy Checklist (PCL-22) is a historical clinician-rated instrument. It was intended to be scored from a semi-structured interview together with collateral records and observed behavior, not from a person's unaided online responses.
The later PCL-R is a different revised instrument. Neither a checklist label nor an online score can establish psychopathy, and misuse can cause serious stigma or harm.
The worksheet, scoring controls, and result categories remain available without calculation changes. Use requires trained professional context, interview information, collateral records, and careful attention to the cited source.
Instructions
Please mark present, unclear, or absent regarding each of the following personality traits or observed behaviors.

While there is no specific cutoff, higher scores indicate a greater likelihood of psychopathy.
