Management of Anankastic (Obsessive-Compulsive) Personality Disorder
Specialized psychotherapy represents the primary evidence-based treatment for anankastic personality disorder, though access remains limited in most healthcare systems. 1
Psychotherapeutic Approaches
Phased Treatment Framework
The most systematic approach involves progressing through five distinct treatment phases, each addressing different problems with tailored interventions 2:
Phase 1 (Safety): Establish treatment frame and address immediate safety concerns, utilizing structured behavioral interventions 2
Phase 2 (Containment): Focus on containment strategies, predominantly using structured behavioral and cognitive interventions 2
Phase 3 (Regulation and Control): Implement cognitive-behavioral techniques and medication if needed to enhance emotional and behavioral regulation 2
Phase 4 (Exploration and Change): Supplement earlier interventions with less structured psychodynamic, interpersonal, and constructionist strategies to explore and modify maladaptive interpersonal patterns and rigid cognitive styles 2
Phase 5 (Integration and Synthesis): Work toward forging a more integrated and adaptive self-structure or identity 2
Specific Therapeutic Modalities
Psychodynamic treatment should be adapted based on the structural level of anankastic symptoms, recognizing that classical obsessional neurosis differs from earlier forms of anankastic disorder 3:
- Different structural levels require specific therapeutic approaches 3
- During psychodynamic treatment, oscillation between different structural levels is possible and should be anticipated 3
- Working through this oscillation represents a key component of the therapeutic process 3
Treatment Duration Considerations
Brief psychotherapy should be considered for most patients as a pragmatic approach, given the expense of routinely offering long-term therapies and the general unavailability of specialized treatments in healthcare systems 1:
- Evidence supports that psychotherapy for personality disorders is cost-effective 1
- Treating most patients more briefly addresses the access problem while maintaining therapeutic benefit 1
Integration of Multiple Interventions
Coordination of multiple interventions is achieved by emphasizing the nonspecific components of therapy, particularly the treatment frame and generic interventions 2:
- Specific interventions from different treatment models, including medication, are built onto this foundation as needed 2
- Treatment should be tailored to the individual patient's presentation 2
- An eclectic approach combining interventions from different therapeutic models delivered in an integrated manner is recommended 2
Clinical Utility of ICD-11 Framework
The ICD-11 dimensional model provides diagnostic validity for anankastia (the trait domain corresponding to OCPD), with factor analyses supporting this domain 4:
- The ICD-11 anankastia domain overlaps substantially with DSM-5 OCPD traits 4
- There is preliminary support for the clinical utility of this dimensional approach 4
- The single diagnosis of personality disorder with severity and domain specifications represents a shift from categorical classification 4
Important Clinical Caveats
Patients with fewer obsessive-compulsive personality traits tend to respond better to treatment, as observed in studies examining various interventions 5:
