Symptoms and traits of personality disorder: Two new methods for their assessment
Psychological Assessment (1993)
  • Lee Anna Clark, University of Iowa

Examines the reliability and validity of 2 dimensional methods for the assessment of personality disorder symptoms and traits. In Study 1, 3 groups that varied in personality pathology level completed the Schedule for Nonadaptive and Adaptive Personality (SNAP; L. A. Clark, 1993), a self-report questionnaire that measures traits relevant to Axis II pathology. Differences among the groups, which were patterned in theoretically interesting ways, are discussed. In Study 2, 2 independent judges rated 22 clusters of Axis II symptoms in 56 state hospital inpatients based on chart information. Good interrater reliability was obtained (median coefficient = .71), and personality-related pathology was quite prevalent. Relations among symptom ratings, SNAP scores, and chart diagnoses were generally systematic, but anomalous findings also emerged. Implications for the dimensional assessment of personality-related pathology are discussed. (PsycINFO Database Record (c) 2009 APA, all rights reserved)
