Assessing DSM–5-oriented level of personality functioning: Development and psychometric evaluation of the Semi-Structured Interview for Personality Functioning DSM–5 (STiP-5.1).

Abstract

The alternative model for personality disorders (AMPD) in the () features a Level of Personality Functioning Scale, measuring intrinsic personality processes that include identity, self-direction, empathy, and intimacy. This study describes the development and psychometric evaluation of a semistructured interview schedule for the multi-item assessment of the level of personality functioning, the Semi-Structured Interview for Personality Functioning (STiP-5.1). Eighty patients and 18 community subjects completed the STiP-5.1. Patients additionally completed the Brief Symptom Inventory, the Severity Indices of Personality Problems, and the Structured Clinical Interview for Axis I and Axis II Personality Disorders. Good interrater reliability was observed in subsamples of patients (n = 40) and nonpatients (n = 18). Associations between the interview scores and conceptually relevant external measures consistently supported the construct validity of the instrument. The STiP-5.1 thus offers a brief, relatively user-friendly instrument with generally favorable psychometric properties for the assessment of level of personality functioning of the AMPD.

Prevalence and structure of self‐other problems in SAPAS screening for personality disorder in a National Sample

“…Accordingly, one of the aforementioned self‐report measures may be employed in a large representative population (Stage 1) followed by structured interviews for impairments in self‐ and interpersonal functioning (Stage 2) with those respondents who are most likely to have a PD. Such “Stage 2” assessment may be carried out using the Structured Clinical Interview for DSM‐5 Alternative Model of Personality Disorders (SCID‐AMPD Module I) or the Semi‐Structured Interview for Personality Functioning DSM–5 (STiP 5.1) …”

“…Importantly, such foci on common PD features independently predict concurrent and prospective psychosocial functioning and risk behaviours, beyond specific personality types/traits and other common mental disorders . Moreover, assessment of general PD features may serve to demarcate personality dysfunction more precisely from other types of mental disorders, and to rate the actual impairment and disability associated with PD …”

A framework for treating DSM‐5 alternative model for personality disorder features

“…Second, clinicians should use validated assessment tools to assess both Criterions A and B features. A variety of tools are available for the assessment of AMPD features, including patient‐report questionnaires (Criterion A; Criterion B), informant‐report questionnaires and diagnostic interviews . An AMPD formulation should be based upon data gathered via evidence‐based assessment tools.…”

Psychometrische Evaluation der deutschen Version des Semistrukturierten Interviews zur Erfassung der DSM-5 Persönlichkeitsfunktionen (STiP-5.1)

“…Für die Domäne Identität umfassen diese: (1) Erleben der eigenen Person als einzigartig, mit klaren Grenzen zwischen sich und anderen; (2) Die niederländische Originalversion des STiP5.1 wurde in einer Stichprobe von 80 PSPatientInnen und einer gesunden Kontroll gruppe (n = 18) validiert. Die psychometrischen Eigenschaften der Originalversion sind als gut zu bezeichnen: Das STiP-5.1 differen ziert zwischen Personen mit und ohne DSMIV PS, korreliert stark mit der Anzahl an DSMIV PS Diagnosen (r = 0,56), Fragebögen zu psychischer Symptomschwere (r = .41) und Persönlichkeitsbeein trächtigungen (r = 0,36-0,51) [14]. Die InterraterReliabilität wurde in einer Substichprobe erfasst (n = 58).…”

Dabei wurde für die Gesamtwertung des Funktionsniveaus der Persönlichkeit ein Intra-Class-Korrelationskoeffizient (ICC) von 0,89 festgestellt [14]. Darüber hinaus weist das STiP5.1 eine hohe Ökonomie auf, mit einer durchschnittlichen Interviewdauer von 50 Min.…”
