Forensic psychiatry is a specific field of practice in child psychiatry where skills are applied for legal purposes and the expert is faced with certain difficulties.

Our objective was to determine the characteristics of the forensic procedure and the clinical profile of the consultants.

Cross-sectional and retrospective descriptive study concerning patients consulting the child psychiatry department of Mongi Slim Hospital between January 2018 and December 2019 in the context of a forensic expertise, excluding administrative expertise. Telephone interviews were carried out for the medicolegal follow-up.

The average age was 9 [+/- 3.1] years and the sex ratio was 0.97. The majority of the requests for expertise came from the specialised unit for violence against women and children (40%). The expert’s task was to carry out a child psychiatric examination in 44% of cases and to establish credibility in 6.8% of cases. Apart from 3 cases of perpetrators, the requests concerned victims of physical (40.1%), sexual (38.6%) and psychological (21.3%) aggression. The assault had taken place within the family in 52% of cases and the alleged aggressor was the father in 36%. The average time between the incident and the request for an expert opinion was significantly longer in cases of sexual assault (p =0.01). The physical assaults concerned more boys (p = 0.05) while those of a sexual nature concerned female children (p=0.005). Victims of sexual aggression showed more sexualised behaviour (p<0.05). No significant differences were found in psychiatric diagnoses according to the type of assault, but an examination without abnormalities was prevalent in cases of psychological assault (p=0.009). Claims were significantly more difficult to interpret in preschool children (p=0.05). Child victims of sexual abuse had more subsequent requests for further investigations (p=0.05) and a judgment, pronounced in 34% of cases, was most often related to psychological abuse (p=0.05).

The practice of forensics requires a specific competence that requires extensive training. Better coordination between the professionals involved is needed as well as the creation of specialised forensic units.
