“…Clark (1993) found that the SNAP scores correlated on average .54 to DSM-IV diagnoses-a coefficient surprisingly high for a self-report instrument. Melley, Oltmanns and Turkheimer (2002) investigated the test-retest reliability and predictive validity of the SNAP; there were satisfactory levels of temporal stability (.58 to .81), however the authors found mixed support for its predictive validity. The SNAP scores did modestly predict cluster A and C PD onset.…”

The definition, classification and assessment of personality disorders (PDs) have attracted considerable debate for nearly 50 years. This paper attempts a comprehensive review of the instruments to assess all, or specific, individual disorders as described in DSM-5, including structured interviews and inventories. The review should be helpful for clinicians, researchers and also industrial and organizational psychologists, to screen and assess the personality pathology spectrum from subclinical manifestations to full blown personality pathology. A decision tree helpful to choose among the different measures is also provided.

“…This diagnostic scale is based on 27 items from the SNAP, with higher scores indicating higher levels of borderline symptoms (α=0.86). Adequate reliability and validity have been shown for this diagnostic scale (e.g., Melley et al, 2002; Reynolds and Clark, 2001). …”

There is a need for a brief measure of emotion dysregulation that can be used in large-scale studies. This study evaluated the construct validity of a short, self-report instrument of emotion dysregulation. Subjects (N=2197) were recruited from primary care clinics of an urban public hospital as part of a study of trauma-related risk and resilience. Emotion dysregulation was measured using the Emotion Dysregulation Scale, short version (EDS-short), a12-item self-report measure assessing emotional experiencing, cognition, and behavior. EDS-short was first compared with the Difficulties in Emotion Regulation Scale (DERS). Then, the construct validity of the EDS-short in predicting depression, posttraumatic stress, substance abuse, borderline pathology, suicide attempts, psychiatric hospitalizations, positive affect, and resiliency was assessed. We found a significant positive correlation between EDS-short and DERS. The EDS-short was significantly predictive of higher reported depressive, posttraumatic stress, substance abuse, and borderline symptoms, and lower reported positive affect and resiliency, over and above demographic characteristics and negative affect. Our results demonstrate that the EDS-short is a useful instrument for measuring emotion dysregulation in traumatized populations. A brief measure of emotion dysregulation is critical as the field moves forward in studying the wide ranging negative effects of emotion dysregulation across psychiatric disorders and outcomes.

“…[19,22] Prior studies have reported good internal consistency and test-retest reliabilities of the SNAP scales, and both the temperament and abnormal personality dimensions show appropriate convergent correlations with other personality inventories. [34,35] Additionally, cross-sectional research has shown the SNAP dimensions to be concurrently associated with internalizing diagnoses in patient populations. [24] In the present study, internal consistency estimates were adequate for all SNAP scales (median Cronbach’s alpha: .80; range: .75–.86).…”

Pathological Personality Traits and the Naturalistic Course of Internalizing Disorders Among High-Risk Young Adults

et al. 2015

Background A diagnosis of personality disorder (PD) signals a negative prognosis for depressive and anxiety disorders, but the precise abnormal personality traits that regulate the temporal course of internalizing psychopathology are unknown. In the present study, we examined prospective associations between abnormal personality traits and the onset and recurrence of internalizing disorders. Methods A sample of 371 young adults at high risk for internalizing problems completed the Schedule for Nonadaptive and Adaptive Personality-Second Edition—a measure of 12 abnormal personality traits and three temperament dimensions (i.e., Negative Temperament, Positive Temperament, Disinhibition versus Control)—and underwent annual diagnostic interviews over four years of follow-up. Results In multivariate survival analyses, Negative Temperament was a robust predictor of both new onsets and recurrences of internalizing disorder. Further, the Dependency and Self-Harm abnormal personality dimensions emerged as independent predictors of new onsets and recurrences, respectively, of internalizing disorders after statistically adjusting for variation in temperament. Conclusions Our findings suggest that abnormal personality traits and temperament dimensions have complementary effects on the trajectory of internalizing pathology during young adulthood. In assessment and treatment settings, targeting the abnormal personality and temperament dimensions with the greatest prognostic value stands to improve the early detection of enduring internalizing psychopathology.
