  1. The Severity Indices for Personality Problems (SIPP) questionnaire:A dimensional measurement for theseverity of personality pathology Helene Andrea (PhD) Roel Verheul (PhD) Viersprong Institute for Studies on Personality Disorders (VISPD), Halsteren, the Netherlands Borderline Congress, Berlin, July 1 2010

  2. Introduction Severity Indices for Personality Problems (SIPP) Verheul, Andrea et al, 2008 Recently developed self-report questionnaire Dimensional measurement for severity of personality functioning -> relevant towards DSM-V Previous research: concurrent validity when comparing PD patients with a non-clinical population Also useful as a dimensional instrument within a clinical population? Verheul, Andrea et al, Psychol Assessment 2008, 20, 23-34

  3. Objective & method Is the dimensional assessment of the severity of personality pathology (SIPP) associated with other indices of the severity of personality pathology in a clinical population? Dimensional measurement of severity of personality pathology Facets (subscales) SIPP Other Indices of severity of personality pathology DSM-IV based measurements:- Presence BPD- Number of PDs- Number of BPD criteria- Cluster A PDs

  4. Study Population • SCEPTRE study: N=2078 patients referred to centers offering psychotherapy for personality problems • Structured Interview for DSM-IV Personality (SIDP-IV): N=379 patients (18%) with BPD - 79.2% female, mean age 30.47 (sd 7.85)- Dimensional scores 16 SIPP facets

  6. SIPP 118 items, 16 facets (subscales), 5 higher-order domains Dimensional measurement of personality severity: Lower score = more maladaptive level of functioning - higher severity Higher score = more adaptive level of functioning – lower severity Examples •     • FullydisagreePartlydisagreePartlyagreeFullyagree Website:http://hdl.handle.net/1765/10066 Publication: Verheul, Andrea et al (2008).

  7. ResultsSIPP facets and BPD diagnosis BPD diagnosis = SIPP-scores more maladaptive

  8. Within the BPD population: SIPP scores associated with number of PDs? Associations between SIPP and DSM-IV severity Indices for 10 (out of 16) facets # BPD criteria Cluster A PDs Comparable pattern

  9. Discussion (1) • Results (modestly) in support of the SIPP as a useful instrument for the dimensional assessment of severity among BPD-patients However…. • Contrast within BPD-patients smaller than between BPD and non-BPD-patients • SIPP specific and sensitive enough??

  10. Further research • Transition: DSM-IV -> DSM-V Proposal DSM-V: • Indicate level of personality functioning for a patient on the “Self and Interpersonal Functioning Continuum” • “Self”: Identity integration, Integrity of Self concept, Self-directnedness“Interpersonal”: Empathy, Intimacy, Cooperativeness, Complexity, Integration of representations of others • 5 levels: No/Mild/Moderate/Serious/Extreme Impairment • How are SIPP-scores related to this continuum? • Dimensional scores and/or cut-off scores? Specificity & sensitivity?
