Dimensions of personality structure among patients with substance use disorders and co-occurring personality disorders: a comparison with psychiatric outpatients and healthy controls

Establishing Levels of Personality Functioning Using the Structured Interview of Personality Organization (STIPO-R): A Latent Profile Analysis

Both the new ICD-11 and the latest Alternative DSM-5 Model for Personality Disorders focus on self and interpersonal functioning as the central feature of personality pathology, also acknowledging that personality disorders are organized along a dimensional continuum of severity. This revised understanding is in line with long-standing psychodynamic conceptualisations of personality pathology, in particular Kernberg's object relations model of personality organization. Despite existing evidence for the clinical utility of the derived Structured Interview of Personality Organization (STIPO-R), empirical support for the identification of clear cut-points between the different levels of personality functioning is missing. For this purpose, a total of 764 adult participants were recruited across two clinical (outpatient and inpatient) settings (n = 250) and two non-clinical (university students and general community) samples (n = 514). Results from the mixture modeling suggested the existence of five groups across the clinical and non-clinical samples that covered: healthy personality functioning, maladaptive personality rigidity, and mild, moderate, and severe levels of personality pathology. All five indicators of personality organization were found to be reliable predictors of personality pathology. Of the five STIPO-R indicators, Aggression and Moral Values had the most discriminative power for differentiating between the Mild, Moderate, and Severe personality disorder groups. Implications of these findings are discussed.

Preliminary psychometric properties of the Chinese version of the structured interview of personality organization (STIPO-CH)

BACKGROUND

Kernberg originally proposed the psychoanalytic concept of personality organization (PO), which measures personality pathology from a dimensional approach with multiple scales and can be evaluated using the Structured Interview of Personality Organization (STIPO) from six domains: identity, object relations, primitive defenses, coping vs. rigidity, aggression, and moral values. The present study translated the original version into the Chinese STIPO (STIPO-CH) version and evaluated its reliability and validity.

METHODS

The STIPO-CH was administered to 49 non-clinical subjects. They also completed the Chinese version of the Inventory of Personality Organization and the Millon Clinical Multiaxial Inventory to evaluate criterion-related reliability. Interrater reliability was assessed with intraclass correlations. An item analysis was carried out to explore the structure and internal consistency.

RESULTS

Interrater reliability (intraclass correlations) ranged from 0.98 to 0.99. Results suggested acceptable internal consistency for identity and moral values. The correlations between STIPO-CH domains and self-report questionnaires indicated that construct validity and criterion-related validity were acceptable to good.

CONCLUSIONS

Overall, this study presents preliminary psychometric properties of STIPO-CH. Limitations regarding the sample, interviewers, and cultural differences are discussed. Future research is highly recommended.

Ability to assess the severity of personality psychopathology based on the Structured Interview of Personality Organization (STIPO) in master's students of "Addictology"

BACKGROUND

With the development of multidisciplinary addictology teams, the ability of an addictologist to reliably assess personality psychopathology can be considered an important prerequisite that significantly enters the process of treatment planning.

AIMS

Verification of the reliability and validity of the assessment of personality psychopathology in master's students of Addictology (addiction science) based on the Structured Interview of Personality Organization (STIPO) scoring course.

METHODS

31 Master's students of Addictology independently evaluated 7 STIPO protocols based on recordings. The presented patients were unknown to the students. The resulting scores of students were compared with 1. expert scores of a clinical psychologist with extensive experience with the STIPO; 2. scores of 4 psychologists without previous experience with the STIPO who have attended the course; 3. information on previous clinical experience and education of the students. The comparison of scores was performed using a coefficient of intraclass correlation, a social relation model analysis and linear mixed-effect models.

RESULTS

Students demonstrated a high degree of inter-rater reliability with a significant degree of agreement in patient assessments, as well as a high to satisfactory degree of validity in the STIPO assessments. An increase in validity after the individual phases of the course was not proven. Their evaluations were generally independent of previous education, as well as diagnostic and therapeutic experience.

CONCLUSIONS

The STIPO seems to be a useful tool to facilitate the communication of personality psychopathology between independent experts within multidisciplinary addictology teams. Training in the STIPO can be a useful addition to the study curriculum.

Object Relations Theory Model of Personality Disorders

Contemporary models of the diagnosis and classification of personality disorders have diverged from the categorical diagnostic framework of the DSM system. One response to this movement can be found in the Alternative DSM-5 Model for Personality Disorders (AMPD), which uses dimensions of personality functioning, coupled with identification of dominant pathological traits, to define and classify personality disorders. By applying psychodynamic object relations theory to the AMPD, therapists can enrich the understanding and assessment of personality functioning and pathology as described in the AMPD.

The Construct Validity of the ICD-11 Severity of Personality Dysfunction Under Scrutiny of Object-Relations Theory

The current classification of personality disorder in ICD-11 includes a description of personality functioning, derived from a number of theoretical paradigms, but most notably consistent with the psychodynamic approach. Concurrently, an object-relations model of personality functioning in a dimensional assessment of severity is provided in the Structured Interview of Personality Organization-Revised (STIPO-R). To date, there are no published measures of International Classification of Diseases-11 (ICD-11) personality severity, though the construct is very comparable to the concepts assessed in the Diagnostic and Statistical Manual of Mental Disorders-5 (DSM-5) levels of personality functioning concept, which is measured by the Level of Personality Functioning Scale-Self-Report (LPFS-SR). This study examined the validity of ICD-11 personality functioning, as measured by the LPFS-SR, by evaluating its associations with the STIPO-R in Kurdistan region. The samples included 231 University students and 419 inpatient participants across four hospitals (267 with a diagnosed personality disorder). All the components of LPFS-SR and STIPO-R were positively and significantly intercorrelated. The components of each measure discriminated PD and non-PD patients from a University, non-clinical group adequately. Despite slightly better performance of the STIPO-R in this discrimination, the measures had a high congruence in predicting personality dysfunction. Overall, the findings of the present study support the validity of ICD-11 construct for evaluating personality functioning.

The Level of Personality Functioning Scale Applied to Clinical Material From the Structured Interview of Personality Organization (STIPO): Utility in Detecting Personality Pathology

The Alternative Model for Personality Disorders states that personality pathology involves significant impairment in personality functioning that can be assessed using the Level of Personality Functioning Scale (LPFS). However, the ability of the LPFS to capture impairments typical of personality pathology, rather than of general psychopathology, is still unclear. The authors applied a 12-item version of the LPFS to clinical interviews (i.e., the Structured Interview of Personality Organization [STIPO]) to test whether differences in levels of impairment in domains related to both self- and interpersonal functioning can be detected among patients with personality disorders (n = 33), psychiatric outpatients (n = 30), and nonclinical controls (n = 30). Results show that the 12-item version of the LPFS scored using clinical material gathered through STIPO interviews captures impairments in identity, self-direction, and empathy uniquely linked to personality pathology. However, impairments in intimacy do not differentiate between patients with and without personality disorders.

The Role of Attachment in Poly-Drug Use Disorder: An Overview of the Literature, Recent Findings and Clinical Implications

Background: Substance use disorders (SUDs) represent a worldwide epidemic with extensive costs to the individual and to society. Occasionally described as an attachment disorder, they have been linked to various impairments in self-regulation and social functioning. However, while there have been significant advances in the development and validation of treatment strategies for SUD in recent years, the components of these treatment approaches have yet to be fully explored. The characteristics of polydrug use disorder (PUD) especially need to be addressed in more detail, as this diagnosis is highly common in individuals seeking treatment, while simultaneously being associated with poor treatment success. Aim and Scope: This review aims at further exploring the relevance of attachment in PUD and its treatment. To this end, this review provides a concise summary of relevant theories on the development and treatment of SUD in general, including related parameters of attachment, emotion regulation, and neuroscience. Furthermore, several studies focused specifically on PUD are described in more detail. These studies explored the connections between attachment, personality structure, primary and higher emotions (including spirituality), as well as structural and functional neural parameters in inpatients with PUD as well as in healthy controls. Most notably, the described studies highlight that insecure attachment and impairments in personality structure are present in inpatients with PUD. In addition, these characteristics are paralleled by extensive impairments in white matter integrity, especially in tracts connected to facets of emotion regulation. Conclusions: Based on our findings, we emphasize conceptualization of PUD as an Attachment Disorder, on a behavioral as well as on a neural level. Furthermore, we point out the importance of an integrated bio-psycho-social approach in this research area. Consequently, future studies might more closely focus on the influence of attachment-based interventions on emotion regulation abilities as well as a potentially related neuroplasticity. Neuroplastic changes, which are still rather unexplored, might represent important parameters for the assessment of treatment outcomes especially in long-term SUD treatment.

Personality functioning in anxiety disorders

BACKGROUND

The Alternative DSM-5 Model for Personality Disorders as well as the upcoming IDC-11 have established a new focus on diagnosing personality disorders (PD): personality functioning. An impairment of self and interpersonal functioning in these models represents a general diagnostic criterion for a personality disorder. Little is known so far about the impairment of personality functioning in patients with other mental disorders than PD. This study aims to assess personality functioning in patients with anxiety disorders.

METHODS

Ninety-seven patients with the diagnosis of generalized anxiety disorder, panic disorder, or phobia, and 16 healthy control persons were diagnosed using the Structured Clinical Interview for DSM-IV (SCID-I and -II) and were assessed by means of the Structured Interview for Personality Organization (STIPO) to determine the level of personality functioning.

RESULTS

While all three patient groups showed significant impairment in personality functioning compared to the control group, no significant differences were observed between the different patient groups. In all three groups of anxiety disorders patients with comorbid PD showed significantly worse personality functioning than patients without. Patients without comorbid PD also yielded a significant impairment in their personality functioning when compared to the control group.

CONCLUSIONS

Anxiety disorders are associated with a significant impairment in personality functioning, which is significantly increased by comorbid PD. There are no differences in terms of personality functioning between patients with different anxiety disorders.

Using the Structured Interview of Personality Organization for DSM-5 Level of Personality Functioning Rating Performed by Inexperienced Raters

We argue that clinical information related to an object-relations model of personality pathology can be used by untrained and clinically inexperienced students to rate personality-disordered patients on the Level of Personality Functioning Scale (LPFS). To do so, 73 clinically inexperienced undergraduate students were asked to assess personality functioning of 10 female inpatients using the LPFS from audio recordings of the Structured Interview of Personality Organization (STIPO). LPFS ratings showed acceptable interrater reliability. Moreover, LPFS ratings were significantly associated with external measures of severity of personality pathology (number of DSM-IV-TR personality disorders) as assessed by experienced clinicians. Finally, the students' ratings were also associated with the level of personality organization as measured by experienced clinicians using the STIPO. Our findings confirm that untrained raters can reliably assess personality pathology by rating the LPFS based on material from the STIPO. Implications related to the use of the STIPO as a tool for the assessment of personality pathology according to the DSM-5 Alternative model are discussed.

Clinician-Guided Assessment of Personality Using the Structural Interview and the Structured Interview of Personality Organization (STIPO)

This article demonstrates the utility of a theory-guided psychodynamic approach to the assessment of personality and personality pathology based on the object relations model developed by Kernberg (1984). We describe a clinical interview, the Structural Interview (SI; Kernberg, 1984), and also a semistructured approach, the Structured Interview of Personality Organization (STIPO; Clarkin, Caligor, Stern, & Kernberg, 2004) based on this theoretical model. Both interviews focus on the assessment of consolidated identity versus identity disturbance, the use of adaptive versus lower level defensive operations, and intact versus loss of reality testing. In the context of a more clinically oriented assessment, the SI makes use of tactful confrontation of discrepancies and contradictions in the patient's narrative, and also takes into account transference and countertransference phenomena, whereas the more structured approach of the STIPO incorporates clinical judgment informed by clinical theory into a well-guided interaction with the patient. Both interviews have good interrater reliability and are coherent with the alternative model for personality disorder diagnosis proposed by the Diagnostic and Statistical Manual of Mental Disorders (5th ed.), Section III. Finally, they provide the clinician with specific implications for prognosis and treatment planning and can rationally guide clinical decision making.

Improving personality/character traits in individuals with alcohol dependence: the influence of mindfulness-oriented meditation

The study of personality is critical to enhance current knowledge of the psychological characteristics of alcohol dependence. Recent evidence shows that mindfulness-oriented meditation positively influences healthy individuals' character. Here, it was assessed whether 8-week mindfulness-oriented meditation promotes similar changes in a group of alcohol-dependent individuals. A control group with alcohol dependence was also tested. Mindfulness-oriented meditation participants showed an increase in the character scores of the temperament and character inventory together with reduced risks of relapse. These longitudinal data highlight the importance of assessing personality in alcohol-dependent individuals and support the utility of therapeutic interventions for alcohol dependence aimed at enhancing individuals' character.

Insecure Attachment Styles and Increased Borderline Personality Organization in Substance Use Disorders

BACKGROUND

Previous research has linked insecure attachment styles and borderline personality organization to substance use disorder (SUD). However, it still remains unclear whether those impairments apply to different kinds of SUDs to the same extent. Therefore, in this study we sought to investigate potential differences regarding attachment deficits and borderline personality organization in two different SUD inpatient groups and furthermore in comparison to healthy controls.

SAMPLING AND METHODS

A total of 66 (24 female) inpatients diagnosed with alcohol use disorder (AUD), 57 (10 female) inpatients diagnosed with polydrug use disorder (PUD), and 114 (51 female) healthy controls completed the Borderline Personality Inventory and the Attachment Style Questionnaire.

RESULTS

Compared to healthy controls, AUD and PUD inpatients showed significant deficits in all attachment parameters (p < 0.01) as well as a significantly increased amount of borderline personality organization (p < 0.01). No differences between AUD and PUD inpatients were observed (p > 0.05).

CONCLUSIONS

Our results indicate that the drug(s) of choice cannot be regarded as an indicator for the extent of attachment deficits or personality pathology. These initial findings are mainly limited by the rather small sample size as well as just a single point of measurement. Future research might also consider further covariates such as comorbidity or psychotropic medication.
