Data collection
Data were gathered through semi-structured interviews
beginning with general questions, gradually progressing
to more specific ones. Probing was performed according
to the reflections of each participant, concerning prior
experiences of the post-crash event; perception about barriers
to PCM; opinions about facilitators of effective PCM;
opinions relating to the role of laypeople at crash scenes;
opinions about the organization and coordination of
PCM. The interviews lasted between 45 and 80 minutes.
They were conducted between March and December
2007.
