Five Factor Model Rating FormFive Factor Model Rating Form (FFMRF; Mullins-Sweatt, Jamerson, Samuel, Olson, & Widiger, 2006) is a brief, one-page instrument for collecting ratings of the Five Factor Model domains and the 30 facets proposed by Costa and McCrae via the NEO Personality Inventory - Revised. Each of the 30 facets is assessed by a single item that is anchored at both the low and high ends by a set of 2-3 adjectives. The FFMRF was originally designed as method for therapists to describe their clients but has also been used and studied as a self-report measure.

Five Factor Obsessive-Compulsive InventoryThe Five Factor Obsessive-Compulsive Inventory (FFOCI; Samuel, Riddell, Lynam, Miller, & Widiger, 2012) is a newly-developed measure of traits relevant to obsessive-compulsive personality disorder from the perspective of the five-factor model (FFM). It has twelve scales that were constructed to assess maladaptive variants of specific FFM facets (e.g., Perfectionism as a maladaptive variant of FFM competence). Full definitions of each trait scale can be found here: FFOCI Definitions. Each scale contains 10 items, for a total of 120 items on the entire measure. Recently a short-form was developed using Item-Response Theory to abbreviate each scale to 4 items, for a total of 48 items.

AB5C - Short FormThe Abridged Big Five-Dimensional Circumplex - Short Form (AB5C-SF; Bucher & Samuel, 2019) is a 135 item version of the larger IPIP-AB5C. Consistent with the AB5C model, there are 45 facets, which are arranged theoretically as a set of primary and secondary loadings across the big five. For example, the domain of Extraversion is populated by 9 facets: One that defines pure extraversion and the remainder that specify extraversion with high and low standings on each of the other domains. Each of the 45 facets is assessed by a three items.
