[Factorial and Convergent Validity of the Short Form of the "Questionnaire of Thoughts and Feelings" (QTF-14) for Borderline Personality Disorder].

The "Questionnaire of Thoughts and Feelings" (QTF) is being used as screening instrument as well as tool for treatment planning and treatment evaluation for patients with borderline personality disorder (BPD). The primary goal of this study was the validation of the dimensional structure of the short version with 14 items, QTF-14. Additionally, item characteristics, reliability and evidence of convergent validity were examined.

[Convergent and Factorial Validity of the Impulsivity and Emotion Dysregulation Scale (IED-27) for Borderline Personality Disorder].

There is a growing consensus that emotion dysregulation is the defining feature of borderline personality disorder, but there are also persisting competing views on the pathology and dimensional structure of the disorder. The "Impulsivity and Emotion Dysregulation Scale" (IED-27) is already being used for assessing patients with borderline personality disorder. The particular aim of this study was to gain evidence of the dimensional structure of the disorder by confirmatory factorial analysis.

A hierarchical analysis of the latent trait of borderline personality disorder and its possible clinical implications.

Borderline personality disorder (BPD) is a severe mental disorder which is accompanied by impaired functioning, complex psychosocial problems and incurs large costs. However, it rarely has been examined whether BPD symptoms form a hierarchical (Mokken) scale, which would imply that symptoms are ordered along a latent dimension of borderline severity. In this study the data from 1,198 inpatients of a psychosomatic clinic were examined.
