Evaluations of [mental state at the time of the offense](https://training.concept.paloaltou.edu/courses/Evaluation-of-Mental-State-at-the-Time-of-the-Offense) (MSO) are among the more complex tasks in criminal forensic assessment.

They also require evaluators to remain alert to cognitive, ethical, and procedural factors that may affect forensic opinions.

They require [a shift from a therapeutic stance to an objective and investigative one](https://www.aapl.org/docs/pdf/Forensic_Assessment.pdf).
