The 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.
