Implementing psychological first aid ontology.

BACKGROUND: This study develops an ontology of Psychological First Aid (PFA) by extracting relevant knowledge from a review of PFA literature. MATERIALS AND METHODS: This study was conducted using the PFA ontology development 101 method. This review processes previously-developed PFA studies by consulting Google Scholar, CINHL, PUBMED, and MEDLINE. Protege 5.0 program was used to integrate with ontology development. The developed PFA ontology consisted of eight super classes: Action agenda, Assessment, Concrete method, Disaster type, Disaster disposition, Purpose, Qualification and Skill, Reaction. In total, 166 terms were collected. RESULTS: The eight super classes were divided into 72 classes and 64 subclasses. The composition yielded in a total of 166 axioms (85 logical axioms; 81 declaration axioms). CONCLUSIONS: This study provides basic data to guide development and composition of PFA arbitration programs.
