The new Swiss criminal code and the recent evolution of evaluation methods have led to change in the three main areas of forensic psychiatry: criminal responsibility, credibility of child sexual abuse allegations, and dangerousness. The assessment of criminal responsibility requires the retrospective examination of the cognitive and volitive capacities of the accused. If needed, mandatory therapeutic propositions that conform to the new criminal code must be recommended. With regard to child sexual abuse allegations, the credibility of the allegations is analysed with specific scales, such as Statement Validity Analysis, interpreted in light of the current state of knowledge in child development and child psychiatry.
