AbstractThis submission contains data and codebooks from several personality studies conducted 1990-2017, organized by assessment instrument. For demographic information about the study participants, please refer to Background Information Questionnaire (BIQ) - Personality Studies (http://d-scholarship.pitt.edu/id/eprint/35424). Studies: 1. Interpersonal Functioning in Borderline Personality ("Interpersonal Functioning") Description: (From Clark et al, 1993): The SNAP is a 375-item self-report inventory, with a true-false format, that assesses 15 traits relevant to personality disorder: 12 primary or lower order dimensions—Mistrust, Manipulativeness, Aggression, Self-harm, Eccentric Perceptions, Dependency, Exhibitionism, Entitlement, Detachment, Impulsivity, Propriety, and Workaholism—were developed first; 3 temperament dimensions—Negative Temperament, Positive Temperament, and Disinhibition (vs. Constraint)—were added later to assess the core of the three higher order factors underlying the primary scales. Data Notes: SNAP scales were created that can be mapped to NEO scales: antagonism, emotional instability, extraversion, and constraint. (Stepp, et. al, 2012) (From Stepp et al, 2012) Internal consistencies ranged from .88 to .95 for the four SNAP scales created to map onto the NEO and TCI.
