Document Summary
Early work by norman (1963) indicated that five factors are necessary: Five-factor solutions were found repeatedly in a wide range of data sources, samples, and instruments. All five factors shown to possess reliability and validity. The neo-personality inventory- revised (neo-pi-r) of costa and mccrae. A strength of the neo-pi-r is that forms are available for both self-report and ratings by others. Research has found : the same five factors are fund in both self-reports and observer ratings, observers agree reasonably well with each other about the standing of individuals on each. Big five dimension: o-data sometimes is a better predictor of personality than s-data. **observation data and self report data differ when a personality trait is not visible or socially desirable** Languages may lack one-to-one transitions; words that translate the same do not necessarily mean the same. Hofstee and colleagues; (1997): compared the meanings of the 5 factors in three different languages: Found considerable congruence except for the openness factor.
