Treatment selection in patients with personality disorders:The role of patient characteristics Helene Andrea Janine van Manen, Anna Bartak, Jan van Busschbach, Roel Verheul Viersprong Institute for Studies on Personality Disorders ISSPD, the Hague, 20 september 2007
IntroductionTreatment selection Influences from: - Patients (psychopathology, motivation, sociodemographics)- Clinicians (reasons for referral, background & experience)- Treatment availability treatment dosages Almost no studies among PD patients Recent study:
Aim Which patient characteristics are related to treatment allocation? Predictors: Patient variables (severity, strength, social role) Outcome: treatment allocation in terms of - Setting - Duration
Method SCEPTRE: • Prospective multi-centre study (six treatment centres)De Viersprong, Gelderse Roos, Altrecht, Zaans Medisch Centrum, Mentrum, GGZ WNB N=928 patients allocated to treatment: • 68% female, mean age 34.1 (9.8) • 87% at least 1 PD - Cluster A 7% - Cluster B 22% - Cluster C 34% - PD NOS 24% - No PD 13%
Prospective design • Intake • Patient characteristics • - Severity • Psychological strength • Social role involvement Selected for treatment (n=928) Setting Duration Outpatient Short Day hospital Long Inpatient
Patient characteristics Severity: SCL-90 (GSI) Axis-II clusters (A/B/C/NOS) Treatment history Social role involvement: Work Care responsibility for children Psychological strengths: Ego strength/identity integration (SIPP) Psychological mindedness (PMAP) Capacity to relate (SIPP) Readiness for change (Motivation for Treatment Questionnaire) Defensive functioning (ODF-score DSQ)
Strongest severity variable:Outpatient history (%) Setting effect
Strongest severity variable:Outpatient history (%) Setting effect No duration effect
Strongest psychological strength variable:Motivation (Readiness for change) Setting effect
Strongest psychological strength variable:Motivation (Readiness for change) Setting effect No duration effect
Strongest social role variable:Care responsibility for children (%) Setting effect
Strongest social role variable:Care responsibility for children (%) Setting effect No duration effect
Discussion Range of patient characteristics predicts treatment selection - Severity, psychological strengths, social role Effectiveness studies comparing different treatment dosages: take baseline differences into account Care for children stronger predictor of treatment allocationthan level of severity or psychological strengths
Further research Operationalisation “dosage” (e.g. intensity) Interactions between patient characteristics eg. high severity + low psychological strength → inpatient & longer duration?eg. patient with same profile with children → outpatient & longer duration?
