What is a forensic expertise in Psychology?

The need for collaboration between Law and Psychology for the proper functioning of the judiciary is becoming more and more evident. Psychology and Law have in common their object of intervention, which is none other than the behavior of the person. In fact, Psychology is an "ally" of Law, because before the questions of Justice, Psychology cooperates in the forum (court or tribunal), and improves the exercise of Law.

One of the roles of a forensic psychologist is to issue expert reports, that is, to be a forensic expert. The forensic expert is in charge of carrying out a psychological evaluation directly associated with the judicial case in charge based on his experience and specific knowledge.

In this sense, a forensic psychologist expert may not issue personal opinions without scientific basis, should not issue professional opinions (p. g., presence of psychopathology) without having evaluated it appropriately, it must not use inappropriate methods of evaluation, it must be impartial and it is obliged to use verified information. In addition, the report issued by the forensic expert must be replicable.

Stages of psychological forensic expertise

Roughly speaking, five major stages can be defined for the preparation of a forensic expertise in Psychology. Depending on the complexity of the matter and the number of people to be evaluated, the process will be more or less long, as well as the fees.

1. Initial contact

The demand is received and an attempt is made to clarify its essential points. At this point the forensic psychologist decides whether to accept or reject the case.

2. Documentation about the case

Exploration of information sources, reading and study of the judicial file, documents, cars, etc.

3. Psychological evaluation

The people involved in the object of the expertise are evaluated. In the report, this section is very important, since the methodology used must be clearly stated. by the expert, the interviews carried out, the techniques used and the date and place of each evaluation.

4. Written report

The clarity of the exposition, the structure of the report and the give a clear and concise answer to the questions asked by the judge or client. At the end of the report, the conclusions and recommendations made by the expert based on the evaluation should appear.

5. Testimony in court

It is about the ratification of the report in oral proceedings. The questioning of the forensic expert by lawyers is common, and there may even be a "confrontation" (interrogation together with another professional of Psychology who normally maintains a position different from the our).

One of the points that generates the most controversy in psychological expert reports are psychiatric diagnoses. We must emphasize that personality descriptions, diagnoses, behavioral predictions... should always be limited to the situation in which the data have been obtained, and he should be especially cautious when making claims based on personal opinions (since they can easily lead to complaints against the psychology professional).

Can any psychologist be a forensic expert?

Unlike the practice of Clinical Psychology (in which to practice in the National Health System one requires the PIR and to practice in private practice the Official Master's Degree in General Psychology is required Sanitary), In Spain there is, for the moment, no current regulation on the practice of Forensic Psychology. This means that any graduate or graduate in Psychology can issue a psychological expert before a Judge, a Court or a People's Jury.

In fact, in most Psychology Colleges there is a list of experts drawn up by the colleges themselves, which is usually opened twice a year. In some schools, such as the College of Psychologists of Catalonia, there is the possibility of accrediting the specialization in Forensic Psychology, after having fulfilled a series of requirements. For a few years, leading professionals in the field, such as María José Catalán, have demanded a state regulatory framework.

We must emphasize that surely few specialties of Psychology require as much preparation and varied knowledge as the field of psychology. Forensic Psychology, and it is strongly recommended, in order to avoid possible complaints, the formal preparation of future experts forensics.
