This study investigated the replicability of a previously proposed personality typology of posttraumatic stress disorder (PTSD, and explored stability of cluster membership over a 6-month period. Participants with current PTSD (n = 156) were drawn from the Collaborative Longitudinal Personality Disorders Study (CLPS). The CLPS project tracked a large sample of individuals who met criteria for 1 of 4 target diagnoses (borderline, schizotypal, avoidant, and obsessive-compulsive) and a contrast group of individuals who met criteria for depression but no personality disorder. A cluster analysis using scales from the Schedule of Nonadaptive and Adaptive Personality yielded 3 clusters: “internalizing,” “externalizing,” and …

There is a dearth of validated self-efficacy (SE) measures in the field of preventive oncology. The objective of this study is to describe the development and validation of a measure to assess patients' perceived ability to obtain the recommended care following an abnormality suspicious for breast cancer. Guided by a social cognitive theory framework, a 51-item measure was developed to explore perceived capability to obtain follow up care under a number of barriers. A multi-step process was utilized to assess the instrument's psychometric properties.

Charles A. Sanislow, Ph.D.

AVPD is a chronic and enduring condition involving a poor sense of self and anxiety in social situations, and it is marked by fears of rejection and a distant interpersonal stance. AVPD may be conceptualized at the severe end of a continuum of social anxiety. In the extreme, traits, mechanisms, and symptoms become integral to chronic dysfunction in personality and interpersonal style. While AVPD is a valid diagnostic construct, the optimal organization of AVPD criteria for the diagnosis, and the …

Gunderson, Carlos M. Grilo, Thomas H. Mcglashan, M. Tracie Shea, Shirley Yen, Charles A. Sanislow, Andrew E. Skodol

Background. Several conceptual models have been considered for the assessment of personality pathology in DSM-5. This study sought to extend our previous findings to compare the long-term predictive validity of three such models: the Five-Factor Model (FFM), the Schedule for Nonadaptive and Adaptive Personality (SNAP), and DSM-IV personality disorders (PDs).

Method. An inception cohort from the Collaborative Longitudinal Personality Disorder Study (CLPS) was followed for 10 years. Baseline data were used to predict long-term outcomes, including functioning, Axis I psychopathology, and medication use.

Results. Each model was significantly valid, predicting a host of important clinical outcomes. Lower-order elements of the …
