Validation of a didactic model evaluating the usability, usefulness and acceptability of psychological first aid teaching through simulation.

Purpose: To evaluate the effectiveness of simulation as a means to teach Psychological First Aid in Operations (PFA-O). We propose to use a model built on research in didactics to assess the factors which may or may not encourage trainers to adopt and embrace this teaching technique.

Material And Method: We submitted a questionnaire to all PFA-O trainers working in France, comprising 15 criteria divided into three dimensions: usability, usefulness and acceptability.

Psychological first aid in operation for military healthcare providers : a study on pre-deployment training.

Introduction: During operational missions, while the management of physical injuries in the field remains the priority, the identification of operational incapacity of psychological origin is necessary as it is equally crucial for the safety of the individual, the group and the mission. The French Military Health Service has developed a Psychological First Aid Training in Operation (PFATO) course based on relational simulations, for military service members. The aim is to identify the early signs of psychological distress in a comrade and to adopt an adapted and protective attitude.

[The hidden faces of school-based violence].

School is an essential place of life for children and adolescents. Like society as a whole, this institution is increasingly exposed to a context of multiple forms of violence, while itself being a source of more or less visible violence. To get out of this school violence, it is necessary to distinguish its hidden sides and to rethink the school as a central place for learning non-violent communication.

Electrochemical assay of the nitrate and nitrite reductase activities of Rhizobium japonicum.

This work describes an electrochemical method for the determination of the nitrate and nitrite reductase activities of Rhizobium japonicum. The advantage of the method lies in the use of whole cells for the analysis and we earlier developed this protocol for the assay of NO. The results obtained are comparable to the spectrophotometric Griess assay.
