Research on personality, especially using the five-factor model (FFM; McCrae & Costa, 1987), has contributed greatly to industrial-organizational (I-O) psychology. In particular, this is because personality traits, especially Conscientiousness, are found to be valid predictors of job performance (Barrick & Mount, 1991; Hurtz & Donovan, 2000) while having relatively less adverse impact than other selection tools, such as cognitive ability tests (Ployhart & Holtz, 2008). Although the FFM is the most widely used personality model, other traits have been studied in the context of work and have been found to correlate with key variables such as job performance and job satisfaction. Such variables include need for achievement (McClelland, Atkinson, Clark, & Lowell, 1976), core self-evaluations (Judge & Bono, 2001), and goal orientation (Phillips & Gully, 1997). As a result, it is of great interest to organizations to be able to understand the personality of its applicants and its incumbents, and often such an examination of traits goes beyond the FFM.
