Abstract

© 2019, Springer Science+Business Media, LLC, part of Springer Nature. The full-length Schedule for Nonadaptive and Adaptive Personality - 2nd Edition (SNAP-2, Clark et al. 2014) and various derivative versions were developed as measures of normal- and pathological-range personality traits. We report herein on the development and initial validation of the SNAP Brief Other-Description Rating Form (SNAP-BORF), an abbreviated version of the SNAP Other-Description Rating Form (ORF; Harlan and Clark Assessment, 6, 131–145, 1999). Our goal was to create a more efficient SNAP informant short form by making items more succinct rather than by eliminating items. SNAP-ORF word count was reduced by 68%, and the 1.5-page SNAP-BORF can be completed in approximately 10 min, one-third to one-half the time required to complete the SNAP-ORF. Mean-level differences between the SNAP-ORF and SNAP-BORF scales were negligible for all scales except propriety. Using exploratory factor analysis, we found the SNAP-BORF had a three-factor structure (NA vs. Low PA, Disinhibition vs. Constraint, and Antagonism) broadly consistent with extant literature. The SNAP-BORF showed good convergent/ discriminant validity with respect to the SNAP-family measures as well as measures of normal personality and symptoms of depression, anxiety, and worry. Results indicated that the SNAP-BORF is a useful measure when a very brief informant assessment of adaptive and maladaptive personality is needed.
