      Stages of psychological forensic expertise

      Basically, five major steps can be delineated for the development of forensic expertise in psychology. Depending on the complexity of the issue and the number of people to be assessed, the process will be more or less long, as will the costs.

      1. First contact

      The request is received and attempts are made to clarify the essential points. At this point, the forensic psychologist decides to accept or reject the case.

      2. Case documentation

      Exploration of sources of information, reading and study of the judicial file, Documents, actions, etc.

      3. Psychological assessment

      The people involved in the object of the evaluation are evaluated. In the report, this section is very important, because it must state very clearly the methodology used by the expert, the interviews carried out, the techniques used as well as the date and place of each evaluation session.

      4. Written report

      It is absolutely essential that the clarity of the presentation, the structure of the report and give a clear and concise answer to the questions asked by the judge or the client. At the end of the report, the conclusions and recommendations made by the expert on the basis of what has been assessed should appear.

      5. Testimony in the courtroom

      This is the ratification of the report during an oral trial. The questioning of a forensic expert by lawyers is common, and even a “collision” can occur (questioning with another professional psychologist who normally maintains a position different from ours).

      Psychiatric diagnoses are one of the most controversial points in expert psychology reports.

      Can a psychologist be a forensic expert?

      Unlike the practice of clinical psychology (in which the PIR is required to practice in the national health system and the official Master in General Health Psychology is required to practice in private consultation), in Spain there are currently no current regulations on the practice of forensic psychology. This means that any graduate or graduate in psychology can issue a psychological expert report before a judge, court or popular jury.

      In fact, in most schools of psychology there is a roster of experts compiled by the schools themselves, which is usually open twice a year. In some schools, such as the College of Psychologists of Catalonia, there is the possibility of accrediting a specialization in forensic psychology, Having satisfied a number of requirements. In recent years, great professionals in the field, such as Maria José Català, have been calling for a state regulatory framework.

      It should be emphasized that few specialties of psychology require as much preparation and varied knowledge as the field of forensic psychology, and it is strongly recommended, in order to avoid possible denunciations, the formal preparation of future experts. forensic.
