The five-factor model (FFM) of personality is obtaining construct vali
dation, recognition, and practical consideration across a broad domain
of fields, including clinical psychology, industrial-organizational p
sychology, and health psychology. As a result, an array of instruments
have been developed and existing instruments are being modified to as
sess the FFM. In this article, we present an overview and critique of
five such instruments (the Goldberg Big Five Markers, the revised NEO
Personality inventory, the Interpersonal Adjective Scales-Big Five, th
e Personality Psychopathology-Five, and the Hogan Personality Inventor
y), focusing in particular on their representation of the lexical FFM
and their practical application.
