SELF-RATINGS AND OBSERVER RATINGS ON THE NEO-FFI IN COUPLES - INITIALEVIDENCE OF THE PSYCHOMETRIC PROPERTIES OF AN OBSERVER FORM

The present study investigated the psychometric properties of the NEO Five-Factor Inventory (NEO-FFI) Observer form of the five-factor model of personality by examining agreement between self-and observer ratin gs. Both partners of 49 young, adult couples rated themselves and thei r partners on the NEO-FFI. The results provide preliminary evidence of the measurement utility of the NEO-FFI Observer form. Specifically, ( a) each personality scale possessed acceptable levels of internal reli ability, (b) five factors consistent with the five-factor model of per sonality emerged in both ratings forms, and (c) there was significant self-observer agreement for all five personality scales. Self-observer agreement was assessed by correlations as well as analyses that test a more stringent definition of agreement. Overall, there is consensus across analyses that points to a substantial amount of concordance bet ween partners' self- and observer ratings.
