This study exploratively investigated a possible relationship between suicidal/self-injurious behavior and the change in self-reported eating disorder symptoms as well as emotional dysregulation and interpersonal difficulties during eating disorder-specific treatment. For this purpose, the symptom index of the Eating Disorder Inventory-2 (EDI-SI) and the scale for the assessment of impulsivity and emotional dysregulation of borderline personality disorder (IES-27) with its subscales suicidal and self-injurious behavior (SVV/SEV), emotional dysregulation (EmotDys) and interpersonal difficulties (BezSchw) were collected from 167 female patients at a psychosomatic clinic. The participants were divided into four groups depending on the occurrence of SVV/SEV before the start and/or end of treatment. A one-way multivariate analysis of variance (MANOVA) with repeated measures showed an interaction of time and SVV/SEV group with regard to EDI-SI, EmotDys and BezSchw. The effect sizes of the pre-post comparison of the EDI-SI were very different in the groups divided according to the occurrence of SVV/SEV (0.27<g*< 1.32). No significant improvement in the EDI-SI was found on average for people with new occurrence of SVV/SEV during the course of treatment. People who were able to cease SVV/SEV in the course of treatment also benefited in terms of the EDI-SI. The decisive factor for the consideration of SVV/SEV in patients with eating disorders appears to be less the SVV/SEV reported before the start of treatment, but rather newly occurring or persistent SVV/SEV during the course of treatment.

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. A diagnostically homogenous sample of patients with BPD (N=3035) of a psychosomatic clinic was presented with several self-assessment inventories, including the QTF-14. The expected single-factor model of the structure of the FGG showed unacceptable model fit indices (CFI=0.751; TLI=0.706; RMSEA=0.115; SRMR=0.073). Exploratory factor analysis showed evidence of two or three specific factors. In a subsequent confirmatory factor analysis, a bifactor model with two specific factors proved to be preferable (CFI=0.956; TLI=0.936; RMSEA=0.054; SRMR=0.034). The internal consistency of the total scale as well as the suggested subscales "Relationship Difficulties and Emotional Dysregulation" and "Autoaggression" was acceptable to good (omega=.81-.84; alpha=.79-.85). Associations with similar scales were as expected. Good psychometric properties of the QTF-14 can be confirmed in this study. Using the suggested subscales could support treatment planning.

Zusammenfassung Der „Fragebogen zu Gedanken und Gefühlen“ (FGG) wird sowohl als Screeninginstrument als auch zur Therapieplanung und -evaluation bei PatientInnen mit Borderline-Persönlichkeitsstörung (BPS) eingesetzt. Primäres Ziel der vorliegenden Studie war die Validierung der zugrundeliegenden faktoriellen Struktur der 14 Items umfassenden Kurzversion FGG-14. Zusätzlich sollten Itemcharakteristika, Reliabilität und Hinweise auf konvergente Validität ermittelt werden. Eine diagnostisch homogene Stichprobe von PatientInnen mit BPS (N=3035) einer psychosomatischen Klinik erhielt verschiedene Selbstbeurteilungsinstrumente, darunter den FGG-14. Das erwartete einfaktorielle Modell der Struktur des FGG hatte keine ausreichende Güte der Modellfitindizes (CFI=0,751; TLI=0,706; RMSEA=0,115; SRMR=0,073). Explorative Faktorenanalysen zeigten Hinweise auf zwei oder drei spezifische Faktoren. In einer erneuten konfirmatorischen Faktorenanalyse erwies sich ein Bi-Faktor-Modell mit zwei spezifischen Faktoren als überlegen (CFI=0,956; TLI=0,936; RMSEA=0,054; SRMR=0,034). Die interne Konsistenz der Gesamtskala sowie der vorgeschlagenen Subskalen „Beziehungsschwierigkeiten und emotionale Dysregulation“ sowie „Autoaggression“ nahm akzeptable bis gute Werte (ω=0,81–0,84; α=0,79–0,85) an. Die Zusammenhänge zu konstruktnahen Skalen waren erwartungsgemäß. Die psychometrischen Gütekriterien des FGG-14 können damit bestätigt werden. Die Betrachtung der Subskalen kann die Behandlungsplanung unterstützen.
