Factor analysis is a multivariate statistical approach commonly used in psychology,
education, and more recently in the health-related professions. This paper will attempt to
provide novice researchers with a simplified approach to undertaking exploratory factor
analysis (EFA). As the paramedic body of knowledge continues to grow, indeed into scale
and instrument psychometrics, it is timely that an uncomplicated article such as this be
offered to the paramedic readership both nationally and internationally. Factor analysis is an
important tool that can be used in the development, refinement, and evaluation of tests, scales,
and measures that can be used in education and clinical contexts by paramedics. The objective
of the paper is to provide an exploratory factor analysis protocol, offering potential
researchers with an empirically-supported systematic approach that simplifies the many
guidelines and options associated with completing EFA.
