Conclusion
Exploratory factor analysis is a complex multivariate statistical approach involving many linear and sequential steps. In addition, many options and rules of thumb apply themselves to EFA emphasising that clear decision sequencing and protocols are paramount in each investigation. The intention of the paper is to provide the paramedic readership with a userfriendly
guide to exploratory factor analysis. It is hoped the Five-step Exploratory Factor Analysis Protocol will be useful (and make research less daunting) in those contemplating undertaking research requiring this statistical technique.
