The impact of level of personality organization on treatment response: a systematic review

Personality organization and anxiety symptoms: Investigating the mediation of perfectionism

BACKGROUND AND AIMS

Personality functioning has increasing significance in the assessment of mental health and mental disorders. Otto Kernberg's model of personality organization is an extensively applied, theoretically grounded approach to categorizing the severity of personality impairment based on intrapsychic and interpersonal functioning. The Inventory of Personality Organization (IPO) self-report rating scale and its 16-item short version were developed to assess personality organization based on this model. This study aimed (i) to examine the factor structure of the short, 16-item version of the IPO, and (ii) to investigate the mediating effect of perfectionism on the relationship between personality organization and anxiety.

METHODS

4340 individuals (mean age 37.7 years; 50.7 % females) were assessed for anxiety (Brief Symptom Inventory) and perfectionism (Multidimensional Perfectionism Scale) besides applying the 16-item IPO.

RESULTS

A bifactor model with three specific factors showed the most optimal levels of model fit for the IPO-16. Only the general personality dysfunction factor was characterized by high levels of internal reliability. Self-oriented and socially prescribed perfectionism mediated the relationship between the general personality dysfunction factor and anxiety symptoms. Higher levels of GPD predicted higher rates of self-oriented and socially prescribed perfectionism, which contributed to more severe symptoms of anxiety.

CONCLUSION

The IPO-16 can be usefully applied to assess a general level of personality dysfunction both in research and in clinical use.

Multidimensional Personality Changes Following Psilocybin-Assisted Therapy in Patients With Alcohol Use Disorder: Results From a Double-Blind, Placebo-Controlled Clinical Trial

OBJECTIVE

Evidence suggests that psilocybin-assisted therapy (PAT) leads to durable shifts in personality structure. However, such changes have yet to be characterized in disorders of addiction. In this secondary analysis from a randomized controlled trial, the authors examined the effect of PAT on personality dimensions in patients with alcohol use disorder (AUD), hypothesizing that PAT would attenuate personality abnormalities in AUD and that reductions in trait impulsiveness would be associated with lower drinking.

METHODS

Eighty-four adults with AUD were randomized to two medication sessions of either psilocybin (N=44) or active placebo (diphenhydramine; N=40), received 12 weekly psychotherapy sessions, and completed follow-up for an additional 24 weeks. Changes in personality traits (week 36 vs. baseline) were assessed with the revised NEO Personality Inventory; daily alcohol consumption was quantified using the timeline followback.

RESULTS

Relative to the placebo group, the psilocybin group showed significant reductions in neuroticism and increases in extraversion and openness. Secondary analyses showed that reductions in neuroticism were driven by decreases in the facets depression, impulsiveness, and vulnerability; increases in openness were driven by increases in the facets openness toward feelings and fantasy. Across all participants, decreases in impulsiveness were associated with lower posttreatment alcohol consumption, and an exploratory analysis revealed that these associations were strongest among psilocybin-treated participants who continued moderate- or high-risk drinking prior to the first medication session.

CONCLUSIONS

PAT elicited durable shifts in personality, suggesting normalization of abnormal personality trait expression in AUD. Further study is needed to clarify whether PAT exerts its beneficial effects by reducing impulsiveness or whether impulsive individuals inherently respond better to PAT.

Unravelling inter-relations within and between psychodynamic constructs and psychopathology using network analysis

Psychodynamic constructs and psychopathology are closely inter-related, but more detailed insight is needed. We investigated these complex inter-relations using network analysis. A Gaussian graphical model in a sample of N = 2232 psychotherapeutic inpatients was estimated. Self-administered questionnaires to assess interpersonal relations (Inventory of Interpersonal Problems-32), psychodynamic conflicts (Operationalized Psychodynamic Diagnosis-Conflict Questionnaire), personality functioning (Operationalized Psychodynamic Diagnosis-Structure Questionnaire-Short Form, Inventory of Personality Organization-Short Form), and psychopathology (Brief Symptom Inventory) were utilized. We investigated the network structure, identified the most inter-related psychodynamic constructs and the psychodynamic constructs with the strongest inter-relations to psychopathology, and explored the clustering of all included constructs. Active and passive conflict processing modes were negatively inter-related in most conflicts. Passive conflict processing modes were more strongly related to psychopathology than active ones in all conflicts, apart from the care versus autarky conflict. Identity diffusion shared the strongest inter-relations within psychodynamic constructs. The psychodynamic constructs that were most strongly related to psychopathology were impairments in self-perception and the passive self-worth conflict. Psychopathology and psychodynamic constructs formed distinct clusters. Our results emphasize the relevance of personality functioning within psychodynamic constructs and in relation to psychopathology.

Relationship Between Clinical Course of Treatment for Burning Mouth Syndrome in Early Period and Aggression Using Rosenzweig Picture Frustration Study: A Retrospective Observational Study

OBJECTIVE

Burning mouth syndrome (BMS) is characterized by a chronic, ongoing sensation of intraoral burning or discomfort without causative lesions. This study sought to examine the relationship between personality traits in patients with BMS using the Rosenzweig Picture Frustration (PF) study, a projective psychological test, and their progress in treatment.

METHODS

Data were collected from outpatients diagnosed with BMS at our clinic between April 2017 and March 2021. The data were analyzed for 28 patients with BMS, of which nine showed improvement earlier than three months (early responders; ER), and the others did not (non-early responders; NER).

RESULTS

The mean visual analog scale (VAS scores for BMS pain at the first visit were 52.8 in the ER and 59.6 in NER (n.s.). No significant differences were detected in the type and direction of aggression between ER and NER in the PF study. In contrast, the group conformity score of the ER (63.7%) was significantly higher than that of the NER (51.4%).

CONCLUSIONS

Personal traits reflected in the PF study may have affected the course of improvement in the BMS. To understand the characteristics of patients with BMS and achieve more favorable treatment outcomes, further study on their personality organization is necessary.

All the Same? Different Measures of Personality Functioning Are Similar but Distinct. A Comparative Study from a Psychodynamic Perspective Using Exploratory Graph Analysis

Personality functioning (PF) is a central construct in many theories of personality pathology. Based on psychodynamic theories, two screening questionnaires to assess PF are widely used: The Inventory of Personality Organization-16 item version and the Operationalized Psychodynamic Diagnosis-Structure Questionnaire Short Form. This study aimed to explore the similarities and differences of the two questionnaires in a large clinical sample of N = 1636 psychotherapeutic inpatients. Correlation analyses were conducted to examine the associations between the global scores and between the subscales. The study further used Exploratory Graph Analysis (EGA) to explore the dimensionality of the items. The stability of estimates was evaluated using a bootstrap version of EGA (bootEGA). The results indicated that the two questionnaires are highly correlated, yet not multicollinear, and moderate to large correlations were found between their subscales. EGA revealed six dimensions that fairly represented the original subscales. BootEGA showed that the dimensions and items were stable, except for one item that did not load sufficiently on any dimension. The findings suggest that although the questionnaires are highly correlated, their subscales tap into distinct domains of PF. We discuss implications stemming from these findings for clinical and scientific practice.

Patient personality and therapist responses in the psychotherapy of adolescents with depressive disorders: toward the Psychodynamic Diagnostic Manual - third edition

Depressive disorders in adolescence pose unique challenges for assessment and treatment, particularly due to their high comorbidity with various personality disorders. Moreover, young depressed patients may elicit very intense and difficult-to-manage emotional responses in therapists (in this context, countertransference). This study aimed at empirically identifying specific personality disorders (or subtypes) among adolescents with depressive pathology and exploring distinct countertransference patterns emerging in their psychotherapy: 100 adolescents (58 with depressive disorders; 42 with other clinical conditions) were assessed by their respective clinicians (n=100) using the psychodiagnostic chart-adolescent of the Psychodynamic Diagnostic Manual (PDM) - second edition, and the therapist response questionnaire for adolescents. Results showed that depressed adolescent patients exhibited marked traits of four personality subtypes (i.e., depressive, anxious-avoidant, narcissistic, and borderline) characterized by different levels of mental functioning and personality organization. These subtypes were predictably related to specific clinicians' emotional responses, even when controlling for the intensity of depressive symptomatology. Patients with depressive or anxious-avoidant personality subtypes evoked more positive countertransference responses, whereas patients with narcissistic or borderline subtypes elicited strong and hard-to-face emotional responses in therapists. Consistent with the next edition of the PDM, the study emphasizes the importance of comprehensive psychodynamic assessment in the developmental age, which frames depressive disorders in the context of accurate emerging personality and mental functioning profiles. This approach, which also relies heavily on the clinician's subjective experience in therapy, provides crucial information on how to specifically tailor interventions that more effectively meet the needs of adolescents with these heterogeneous and complex clinical conditions.

Narcissistic dimensions and depressive symptoms in patients across mental disorders in cognitive behavioural therapy and in psychoanalytic interactional therapy in Germany: a prospective cohort study

BACKGROUND

Narcissistic personality traits have been theorised to negatively affect depressive symptoms, therapeutic alliance, and treatment outcome, even in the absence of narcissistic personality disorder. We aimed to examine how the dimensional narcissistic facets of admiration and rivalry affect depressive symptoms across treatment modalities in two transdiagnostic samples.

METHODS

We did a naturalistic, observational prospective cohort study in two independent adult samples in Germany: one sample pooled from an inpatient psychiatric clinic and an outpatient treatment service offering cognitive behavioural treatment (CBT), and one sample from an inpatient clinic providing psychoanalytic interactional therapy (PIT). Inpatients treated with CBT had an affective or psychotic disorder. For the other two sites, data from all service users were collected. We examined the effect of core narcissism and its facets admiration and rivalry, measured by Narcissistic Admiration and Rivalry Questionnaire-short version, on depressive symptoms, measured by Beck's Depression Inventory and Patient Health Questionnaire-Depression Scale, at baseline and after treatment in patients treated with CBT and PIT. Primary analyses were regression models, predicting baseline and post-treatment depression severity from core narcissism and its facets. Mediation analysis was done in the outpatient CBT group for the effect of the therapeutic alliance on the association between narcissism and depression severity after treatment.

FINDINGS

The sample included 2371 patients (1423 [60·0%] female and 948 [40·0%] male; mean age 33·13 years [SD 13·19; range 18-81), with 517 inpatients and 1052 outpatients in the CBT group, and 802 inpatients in the PIT group. Ethnicity data were not collected. Mean treatment duration was 300 days (SD 319) for CBT and 67 days (SD 26) for PIT. Core narcissism did not predict depression severity before treatment in either group, but narcissistic rivalry was associated with higher depressive symptom load at baseline (β 2·47 [95% CI 1·78 to 3·12] for CBT and 1·05 [0·54 to 1·55] for PIT) and narcissistic admiration showed the opposite effect (-2·02 [-2·62 to -1·41] for CBT and -0·64 [-1·11 to -0·17] for PIT). Poorer treatment response was predicted by core narcissism (β 0·79 [0·10 to 1·47]) and narcissistic rivalry (0·89 [0·19 to 1·58]) in CBT, whereas admiration showed no effect. No effect of narcissism on treatment outcome was discernible in PIT. Therapeutic alliance mediated the effect of narcissism on post-treatment depression severity in the outpatient CBT sample.

INTERPRETATION

As narcissism affects depression severity before and after treatment with CBT across psychiatric disorders, even in the absence of narcissistic personality disorder, the inclusion of dimensional assessments of narcissism should be considered in future research and clinical routines. The relevance of the therapeutic alliance and therapeutic strategy could be used to guide treatment approaches.

ICD-11 personality disorder features in the danish general population: Cut-offs and prevalence rates for severity levels

INTRODUCTION

Prevalence rates and correlates of personality disorders (PD) are relevant to health care policy and planning.

OBJECTIVES

To present normative data for self-reported ICD-11 personality disorder (PD) features including tentative cut-off scores and prevalence rates for severity levels along with psychosocial correlates.

METHODS

The Personality Disorder Severity ICD-11 (PDS-ICD-11) scale and criterion measures of impairment were administered to a social-demographically stratified sample of Danish citizens (N = 8,941) of which 3,044 delivered complete data. Item-Response Theory (IRT) was employed to indicate cut-offs based on standard deviations from the latent mean.

RESULTS

The unidimensionality of the PDS-ICD-11 score was supported and IRT analysis suggested norm-based thresholds at latent severity levels. Expected associations with criterion measures were found.

CONCLUSION

The normative data portray ICD-11 PD features in the general population and allow for interpretation of PDS-ICD-11 scores (e.g., scores of 12, 16, and 19 may indicate mild, moderate, and severe dysfunction), which may inform health care policy and planning. A total weighted prevalence of 6.9 % of the Danish general population is estimated to have clinically significant personality dysfunction, proportionally composed of Mild (4.8 %), Moderate (1.2 %), and Severe (0.9 %) levels. Future research should corroborate these findings using relevant clinical samples and methods.

[The relationship of functional and symptomatic changes after multimodal psychodynamic treatment]

Objectives: Personality organization or functioning describes biographically acquired characteristics for the regulation of psychological processes. Limitations correlate with symptom load. This study examines whether significant improvement in personality functioning can be achieved in the framework of a multimodal psychodynamic treatment and its influence on the psychological symptoms. Methods: In this naturalistic study design (N = 318) personality organization was measured with the OPD-SQS and the symptoms were obtained using PHQ-9, GAD-7, SCL-9 and mini- Spin. Changes in the functioning levels were calculated using a t-test. The associations between the functional and symptom improvements were calculated using hierarchical regressionmodels. ANOVAs for dependent samples were used to calculate the association of the personality organization changes on symptom reduction Results: Treatment resulted in significant improvement in personality structure.The greater the changes, the lower the symptom burden at the end of treatment. Patients with lower personality structure benefited equally well from treatment. Conclusions: Personality functioning improves with multimodal psychodynamic therapy and is accompanied by reduction of psychological symptoms. Structural changes proceed equally in high and low structured patients.

Psychotherapy readiness domains as predictors of psychotherapy outcome in trauma-affected refugees

INTRODUCTION

Little is known about predictors of psychotherapy outcome in trauma-affected refugees. Knowledge on outcome predictors can help clinicians identify patients prior to treatment who are not likely to benefit from standardized psychotherapy and take additional measures to adjust treatment to the individual patient. Given the dynamic nature of psychotherapy readiness domains, they represent potential targets to be worked with in therapy in order to improve outcomes.

METHODS

Psychotherapy readiness domains (locus of control, cognitive functioning, motivation for therapy, and personality functioning) were examined as potential predictors of psychotherapy outcome in trauma-affected refugees. Secondary analyses were conducted on data from a pragmatic randomized controlled trial. Study participants (N = 190) were refugees with PTSD who received flexible manual-based Cognitive Behavioral Therapy (CBT) at a psychiatric outpatient clinic in Denmark. Psychotherapy readiness domains were assessed via semi-structured interviews at the beginning of psychotherapy. Outcome variables were pre-post change in PTSD symptomology and global level of functioning.

RESULTS

Multiple regression analyses revealed that higher motivation for psychotherapy predicted improvement in PTSD symptomology and global level of functioning. Moreover, higher cognitive functioning predicted improvement in global level of functioning.

LIMITATIONS

The predictor rating scales need further psychometric evaluations in cross-cultural contexts.

CONCLUSIONS

These findings highlight the importance of considering motivation in psychotherapy offered to trauma-affected refugees. Further research is needed to identify potential barriers to motivation in this diverse patient population and to determine whether motivational interventions can lead to improved treatment outcomes.

Exploring the associations between psychodynamic constructs and psychopathology: A network approach

Psychodynamic therapy effectively reduces symptomatology by focusing on underlying (unconscious) processes instead of symptoms. Nevertheless, the exact interrelationship between psychodynamic constructs and psychopathology remains unclear. This study uses network analysis to explore these associations. We computed a cross-sectional partial correlation network between psychodynamic constructs (i.e., personality functioning, interpersonal relations, and active and passive modes of intrapsychic conflicts according to the Operationalized Psychodynamic Diagnostics [OPD] system) and psychopathology (i.e., depression and somatization) in a naturalistic sample of 341 adults registering for psychodynamic outpatient therapy. We estimated node centrality, node predictability, and bridge symptoms and used community detection analysis. Bootstrap methods were applied to assess network stability. Psychodynamic constructs and psychopathology resulted in separate but connected clusters. Personality functioning emerged as the most influential node in the network and was bridging the clusters. The network was found to be highly stable, allowing reliable interpretations. The results offer important insights on how psychodynamic constructs relate to psychopathology, which can be used to inform treatment approaches. The findings suggest that personality functioning may be an important intervention target. However, future research is needed to include a broader range of diagnoses. In addition, longitudinal studies may clarify the direction of causality.

Organization of Clinician-Rated Personality Disorder Types According to ICD-11 Severity of Personality Dysfunction

Objective: The International Classification of Diseases, 11th edition (ICD-11) model of personality disorders (PD) allows clinicians to classify personality dysfunction according to four levels of severity. This approach is partially inspired by Kernberg's levels of personality organization, in which various PD types are organized according to their level of severity. This study sought to investigate whether the established ICD-10 PD categories can be organized according to the four levels of ICD-11 PD severity, and to what extent this organization aligns with Kernberg's four levels of personality organization. Method: A sample of 247 patients were rated by their mental health professionals according to ICD-10 PD categories and ICD-11 PD severity levels. Results: The frequencies of ICD-10 PDs on the different ICD-11 PD severity levels were generally found to be consistent with Kernberg's model. Accordingly, borderline and antisocial PDs predominantly occurred at the most severe levels, whereas anankastic, avoidant, and dependent PDs typically occurred at the milder levels. Only paranoid and histrionic PDs were less consistent with Kernberg's model. Conclusions: The findings indicate that the new ICD-11 PD severity dimension largely aligns with Kernberg's model of personality functioning with respect to the organization of PD types. Clinicians may therefore conceptualize familiar PD types in terms of their ICD-11 PD severity and vice versa.

A bifactor model of personality organization in adolescence: the validity of a brief screening measure assessing severity and core domains of functioning

BACKGROUND

Both the latest edition of the DSM-5 as well as the new ICD-11 have established a new focus in the diagnosis of personality disorders: the assessment of personality functioning. This recent shift in focus converges with long-standing psychodynamic conceptualizations of personality pathology, particularly Kernberg's object relations model. Although a significant amount of research supports these models in adults, much less is known about the validity of these frameworks in youth. Considering the paucity of brief measures of personality functioning in adolescents, the current study aimed to develop and investigate the validity of the Inventory of Personality Organization for Adolescents-Short Form, a theoretically-informed measure assessing severity and core domains of functioning in adolescents.

METHODS

A total sample of N = 525 adolescents aged 13 to 19 years were recruited through a community University-Health Psychology Clinic as current patients (n = 94) or who responded to an online research call (n = 431).

RESULTS

Results indicate that a bifactor model provided the best fit to the data and consisted of a general factor reflecting core self-other functioning and three specific factors, representing additional dimensions of personality organization.

CONCLUSIONS

A brief 15-item version of the IPO-A was successfully derived for time-efficient screening of personality pathology in youth. Similarities with the ICD-11 framework are discussed.

Reliability and factorial validity of long and brief versions of the inventory of personality organization in a Latvian sample

The aim of this study was to examine the construct validity and reliability of long and brief versions (57 and 16 items) of the Inventory of Personality Organization (IPO) in a Latvian non-clinical sample. The actuality of this study is dictated by the number of persons suffering from personality disorders, and the excessive need for reliable constructs for the assessment of personality in the normality-abnormality range. The total number of participants of the study was 1118, recruited in several subsamples, which were employed for the investigation of the factor structure, psychometric properties, test-retest, and convergent validity of the IPO-57 and IPO-16 scales. The 3-factor structure, obtained by confirmatory factor analysis, was replicated in the Latvian-speaking sample for long and brief IPO versions. Both constructs achieved adequate model fit psychometric indices and sufficient internal consistency, and the test-retest reliability was also approved. The convergent validity of IPO with aggressivity, negative affectivity, and non-adaptive personality measures was established. In the current study, we adapted a very fundamental psychodynamic/psychoanalytic construct in the Latvian language and replicated the previously empirically established IPO three-dimensional model, whereas the novelty in IPO construct convergent validity research was the establishment of convergent validity with non-adaptive personality traits measured by the Personality Inventory for DSM-5 Brief Form (PID-5-BF). Both versions of IPO are recommended for further use in the research in Latvian language samples, for clinical purposes to assess the level of psychic functioning, and for treatment planning and evaluation purposes.

Psychological Mindedness, Personality Structure, and Outcomes in Short-Term Group Analytic Psychotherapy

The present study investigated the treatment effects of focused short-term group analytic psychotherapy and examined whether outcomes were predicted by the client's psychological mindedness and personality structure as measured by the Operationalized Psychodynamic Diagnosis (OPD). Treatment foci were formulated according to the OPD for 66 student counseling clients across nine groups. Two observers independently rated client psychological mindedness and personality structure. The pre-post Cohen's d effect sizes were large on the Global Severity Index (GSI) and the Inventory of Interpersonal Problems (IIP-64) and moderate on the Social Adjustment Scale Self Report, including all 66 clients starting treatment. Psychological mindedness significantly predicted two outcomes (GSI, IIP), and personality structure predicted one outcome (GSI). These measures could be helpful when selecting clients for short-term group analytic psychotherapy. We discuss study limitations and implications for future research and practice.

Ego Impairment Index (EII-2) as a predictor of outcome in short- and long-term psychotherapy during a 5-year follow-up

Objective

This study examined the predictive ability of the Rorschach‐based Ego Impairment Index (EII‐2) on outcome of psychotherapy in different types and durations of therapy.

Method

A total of 326 outpatients suffering from depressive or anxiety disorders were randomized into receiving solution‐focused (n = 97), short‐term psychodynamic (n = 101), or long‐term psychodynamic psychotherapy (n = 128). Psychotherapy outcome assessments during the 5‐year follow‐up period covered psychiatric symptoms, social functioning, and work ability.

Results

Lower EII‐2 values, which indicate less problematic ego functioning, were found to predict faster improvement in both short‐term therapies as compared to long‐term psychotherapy.

Conclusion

The results provide preliminary support for the utility of EII‐2 as a complementary measure to interview‐based methods for selecting between short‐ and long‐term therapies.

Potential efficacy of parent-infant psychotherapy with mothers and their infants from a high-risk population: a randomized controlled pilot trial

Background

Psychotherapy of mother-child dyads is an intervention which was developed to prevent maltreatment and negative children’s development. There is a lack of good-quality research investigating psychotherapeutic interventions and social care for mothers at high-risk living in Mother-Child Facilities in Germany. The present randomized controlled pilot trial (RCT) aimed to evaluate the need for parent-infant psychotherapy (PIP) and to explore its impact on the mother-infant relationship. Primary feasibility objectives were recruitment and attrition, with potential efficacy defined as the secondary feasibility objective.

Methods

This pilot RCT focused on (young) mothers with cumulative risk factors and their infants under 7 months of age living in Mother-Child Facilities. N=32 mother-child dyads were randomly allocated to PIP or Care as usual (CAU). Outcomes were assessed at baseline, 3 months, and 6 months of intervention. The primary potential efficacy outcome was maternal sensitivity. Secondary outcomes were maternal mental health problems, reflective functioning, parenting stress, personality organization, infant’s development, and attachment.

Results

At baseline, all mothers showed low levels of emotional availability, but results revealed improvements in sensitivity, mental health problems, stress, and depressive symptomatology favoring PIP after 6 months. Positive developments in maternal sensitivity, a healthy aspect of mother-child interaction, were only found in the PIP group. Overall attrition was high at 6 months. Some evidence of fewer depressive symptoms and lower maternal distress after 6 months of PIP-intervention exists that did not reach significance.

Conclusion

Findings revealed improvements in the mother’s well-being for both groups, but PIP had a higher impact on the mother-child dyad. In sum, there is some evidence that PIP may represent an effective intervention offer besides the social and pedagogical support in these facilities, but further research is demanded.

God Representation Types Are Associated With Levels of Personality Organization and Christian Religious Orthodox Culture

ABSTRACT

This exploratory study shows that God representation types are associated with levels of personality organization. Among two Dutch samples of psychiatric patients (n = 136) and nonpatients (n = 161), we found associations between the psychotic, borderline, and neurotic personality organizations, and passive-unemotional, negative-authoritarian, and positive-authoritative God representation types, respectively. Both patients and nonpatients reported positive God representations, but only nonpatients and higher-level functioning patients reported an integrated God-object relation. For persons with personality pathology, the relationship with God can be a struggle and might have a defensive and/or compensating function. In addition to personality organization, Christian religious orthodox culture is a statistical predictor of God representations, but not of anger toward God. We offer suggestions for how psychotherapeutic work with God representations might differ for patients with different levels of personality organization.

Development and initial evaluation of the ICD-11 personality disorder severity scale: PDS-ICD-11

AIM

No measure has formally been developed to assess the published ICD-11 model of Personality Disorder (PD) severity. We therefore set out to develop and evaluate the 14-item Personality Disorder Severity ICD-11 (PDS-ICD-11) scale.

METHOD

A representative U.S. community sample (N = 428; 50.9% women) and a New Zealand mental health sample (N = 87; 61.5% women) completed the PDS-ICD-11 scale along with a series of established PD and impairment measures.

RESULTS

Item response theory supported the unidimensionality of PDS-ICD-11 (median item loading of 0.68) and indicated that a PDS-ICD-11 score of 17.5 may serve as a benchmark for pronounced dysfunction. Correlation and regression analyses supported both criterion validity and incremental validity in predicting impairment and PD symptoms. The PDS-ICD-11 was particularly associated with measures of Level of Personality Functioning Scale (LPFS), Global PD severity, and Borderline PD symptom score. A comparison between clinical individuals diagnosed with an ICD-11 PD vs. no PD supported diagnostic validity.

CONCLUSION

This initial construction study suggests that the PDS-ICD-11 constitutes a promising instrument that provides a quick impression of the severity of personality dysfunction according to the official ICD-11 PD guidelines. Clearly, more research is needed to corroborate its validity and utility. The PDS-ICD-11 scale is provided as online supporting information.

Three Dimensional Approaches to Personality Disorders: a Review on Personality Functioning, Personality Structure, and Personality Organization

PURPOSE OF REVIEW

The concept of personality functioning (Alternative DSM-5 Model of Personality Disorders) has led to increased interest in dimensional personality disorder diagnosis. While differing markedly from the current categorical classification, it is closely related to the psychodynamic concepts of personality structure and personality organization. In this review, the three dimensional approaches, their underlying models, and common instruments are introduced, and empirical studies on similarities and differences between the concepts and the categorical classification are summarized. Additionally, a case example illustrates the clinical application.

RECENT FINDINGS

Numerous studies demonstrate the broad empirical basis, validated assessment instruments and clinical usefulness of the dimensional concepts. Their advantages compared to the categorical approach, but also the respective differences, have been demonstrated empirically, in line with clinical observations. Evidence supports the three dimensional concepts, which share conceptual overlap, but also entail unique aspects of personality pathology, respectively.

Naturalistische Studie zur Wirksamkeit stationärer psychodynamischer Psychotherapie

Die naturalistische Studie mit 552 Patienten erfasst die Wirksamkeit stationärer psychodynamischer Psychotherapie auf Symptombelastung, Mentalisierungsfähigkeit und strukturelle Beeinträchtigung mit dem Gesundheitsfragebogen für Patienten (deutsche Übersetzung des Patient Health Questionnaire, PHQ‑D), dem Mentalisierungsfragebogen (Mentalization Questionnaire, MZQ) sowie mit der 16-Item-Version des Inventars der Persönlichkeitsorganisation (IPO-16). Alle Fragebogen wurden von den Patienten vor und nach der Behandlung ausgefüllt. Im Ergebnis zeigten sich auf allen Skalen hochsignifikante Verbesserungen vom Beginn zum Ende der Therapie. Dabei verbesserten sich Patienten mit emotional instabiler Persönlichkeitsstörung („borderline personality disorder“, BPD) am Behandlungsende um das Doppelte, verglichen mit Patienten ohne BPD, bezüglich Mentalisierungsfähigkeit und struktureller Beeinträchtigung. Die Wirksamkeit stationärer psychodynamischer Psychotherapie auf Symptombelastung, Mentalisierungsfähigkeit und strukturelle Beeinträchtigung konnte eindrücklich gezeigt werden. Die Effektstärken liegen im Bereich ähnlicher Untersuchungen. Zwischen Beeinträchtigung der Mentalisierungsfähigkeit und struktureller Beeinträchtigung wurden starke Zusammenhänge gefunden. Ebenso hängen die Veränderungen im MZQ und IPO-16 mit den Symptomveränderungen zusammen. Die Ergebnisse dieser Studie unterstreichen die Relevanz stationärer psychodynamischer Therapie.

[Personality organization and mentalization of depressive inpatients in a long-term-study]

Personality organization and mentalization of depressive inpatients in a long-term-study Objectives: In a naturalistic long-term follow-up design this study investigated the improvement of depressive symptom severity, mentalization deficiency and personality organization. Methods: 300 patients with depressive symptoms were assessed at three evaluation times (before therapy, after therapy and one to three years after discharge) with the Patient Health Questionnaire Depression Scale (PHQ-9), the Mentalization Questionnaire (MZQ) and the Inventory of Personality Organization (IPO-16). Results: Patients improved significantly in depressive symptom severity with strong impact. Especially patients with severe depression symptoms improved in mentalization deficits and personality organization during and after inpatient treatment. Chronic depressive patients improved in mentalization rather than in personality organization. Depressive symptom severity correlates with mentalization deficits and structural impairment. Discussion: Mentalization deficits differed depending on the severity of depression, as other studies already showed. The more severe depressive symptoms, the more likely mentalization deficits and structural impairment improved. However, the lack of control groups limits the causal proof of efficacy. Mentalization deficits and personality organization should be recorded timely in order to choose adequate technique.

How does level of personality functioning inform clinical management and treatment? Implications for ICD-11 classification of personality disorder severity

PURPOSE OF REVIEW

The International Classification of Diseases, 11th Edition (ICD-11) classifies personality disturbance according to levels of severity. This article reviews the literature on levels of personality functioning in relation to clinical management and treatment, and proposes how these findings apply to the ICD-11 classification of personality disorders.

RECENT FINDINGS

Findings were primarily derived from studies using the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) Level of Personality Functioning Scale (LPFS), Kernberg's Level of Personality Organization, and the general P-factor of personality disorder. Severity of personality dysfunction is related to treatment outcome, risk of dropout, therapeutic alliance, readiness for treatment, risk of harm to self or others, risk of dissociation and psychotic-like breaks, coherence in narrative identity, reflective functioning, and epistemic trust.

SUMMARY

The overall level of personality disorder severity indicates risk of negative outcomes and may be used as decision tool for 'personalized medicine' and required treatment intensity (e.g., strength of alliance and the need for establishing epistemic trust). Beyond the ICD-11 guidelines for determining personality disorder severity, these implications also apply to practitioners using comparable frameworks such as the DSM-5 LPFS and Kernberg's Level of Personality Organization. Future research should focus on the interaction of severity with trait qualifiers in relation to clinical management.

Assessing Level of Personality Organization With the Psychodiagnostic Chart: A Validity Study

Heterogeneity within diagnostic types and comorbidity across diagnostic groups render a specific personality disorder anything but specific, leading researchers and clinicians to increasingly focus on the general severity of personality pathology. Personality pathology severity is reflected in one's level of personality organization (LPO) and research has demonstrated that LPO is a significant predictor of treatment response. This investigation examined the reliability and validity of the Psychodiagnostic Chart (PDC) in assessing the LPO dimension of the Psychodynamic Diagnostic Manual (PDM; PDM Task Force, 2006). Among a sample of 88 urban-dwelling women seeking primary medical care, the LPO dimension of the PDC received fair to good interrater reliability among 6 psychodynamic psychologists. Convergent validity was demonstrated with contrast analysis and individual correlations that yielded statistically significant associations between LPO scores and conceptually related psychodynamic variables (e.g., defensive functioning, object relations) and self-reported personality pathology scores. Support for discriminant validity was limited by the modest power associated with the sample size. Exploratory analyses examining LPO scores and measures of physical health and intimate partner violence were conducted. Our results supported the reliability, validity, and practical use of the LPO dimension of the PDC.

The prediction of the level of personality organization on reduction of psychiatric symptoms and improvement of work ability in short- versus long-term psychotherapies during a 5-year follow-up

OBJECTIVES

How level of personality organization (LPO) predicts psychiatric symptoms and work ability in short- versus long-term psychotherapies is poorly known. We investigated the importance of the LPO on the benefits of short-term versus long-term psychotherapies.

DESIGN

A cohort study based on 326 outpatients with mood or anxiety disorder was allocated to long-term (LPP) and short-term (SPP) psychodynamic psychotherapy, and solution-focused therapy (SFT).

METHODS

The LPO was assessed by interview at baseline and categorized into neuroses and higher level borderline. Outcome was assessed at baseline and 4-9 times during a 5-year follow-up, using self-report and interview-based measures of symptoms and work ability.

RESULTS

For patients receiving SPP, improvement in work ability, symptom reduction, and the remission rate were more considerable in patients with neuroses than in higher level borderline patients, whereas LPP or SFT showed no notable differences in effectiveness in the two LPO groups. In patients with neuroses, improvement was more considerable in the short-term therapy groups during the first year of follow-up, and in higher level borderline patients LPP was more effective after 3 years of follow-up. The remission rate, defined as both symptom reduction and lack of auxiliary treatment, was higher in LPP than in SPP for both the LPO groups considered.

CONCLUSIONS

In neuroses, short-term psychotherapy was associated with a more rapid reduction of symptoms and increase in work ability, whereas LPP was more effective for longer follow-ups in both LPO groups. Further large-scale studies are needed.

PRACTITIONER POINTS

Level of personality organization is relevant for selection between short- and long-term psychotherapies. Short-term therapy gives faster benefits for neurotic patients but not for patients with higher level borderline personality organization. Sustained remission from symptoms is more probable after long-term than short-term therapy.

Impact of personality status on the outcomes and cost of cognitive-behavioural therapy for health anxiety

BACKGROUND

Health anxiety, hypochondriasis and personality disturbance commonly coexist. The impact of personality status was assessed in a secondary analysis of a randomised controlled trial (RCT).

AIMS

To test the impact of personality status using ICD-11 criteria on the clinical and cost outcomes of treatment with cognitive-behavioural therapy for health anxiety (CBT-HA) and standard care over 2 years.

METHOD

Personality dysfunction was assessed at baseline in 444 patients before randomisation and independent assessment of costs and outcomes made on four occasions over 2 years.

RESULTS

In total, 381 patients (86%) had some personality dysfunction with 184 (41%) satisfying the ICD criteria for personality disorder. Those with no personality dysfunction showed no treatment differences (P = 0.90) and worse social function with CBT-HA compared with standard care (P<0.03) whereas all other personality groups showed greater improvement with CBT-HA maintained over 2 years (P<0.001). Less benefit was shown in those with more severe personality disorder (P<0.05). Costs were less with CBT-HA except for non-significant greater differences in those with moderate or severe personality disorder.

CONCLUSIONS

The results contradict the hypothesis that personality disorder impairs response to CBT in health anxiety in both the short and medium term.

Psychopathological Functioning Levels (PFLs) and their possible relevance in psychiatric treatments: a qualitative research project

BACKGROUND

Symptoms description is often not enough to provide clinicians with guidelines for treatments and patients' clinical history does not represent an exhaustive source of data. Psychopathological dysfunctions are known to relate to the core disturbances that underlie different forms of psychopathology so the identification of such dysfunctions could be helpful for treatments. Some tools are available although highly complex and lengthy. This study aimed to provide clinicians with an easy-to-administer instrument able to capture different levels of impairment in psychopathological functioning, namely the Psychopathological Functioning Levels - Rating Scale (PFL-RS).

METHODS

The Psychopathological Functioning Level - Research and Training Committee (PFL-RTC) has been established in Turin since 2002 including psychiatrists and clinical psychologists with extensive clinical and research experience. Our research was grounded on the Qualitative Research Criteria (QRC) 1-7 and conducted with subsequent steps in order to identify those core psychopathological dysfunctions to be rated by this tool.

RESULTS

From 2002 until 2014, 316 outpatients were administered the clinical interview on at least two different occasions. Diagnoses were mixed and included: Schizophrenic and Psychotic Disorders, Depressive Disorders, Anxiety Disorders, Obsessive-Compulsive Disorder, Post- Traumatic Stress Disorder, Somatic Symptoms Disorders, Eating Disorders and Personality Disorders. Focus groups were conducted to identify those psychopathological dysfunctions which needed to be rated, according to two Phenomenological Selection Criteria (PhSC) and four Etiopathogenetic Selection Criteria (EtSC). As a result, five dysfunctional areas emerged: Identity (ID); Comprehension (CO); Negative Emotions (NE); Action-Regulation (AR); Social Skills (SS). After checking such dimensions for consistency with the existing instruments, 7 levels of severity were identified for each area. Finally, a provisional Italian schedule of Psychopathological Functioning Levels - Rating Scale (PFL-RS) was obtained and checked for semantic comprehension and then administered gathering preliminary data.

CONCLUSIONS

Psychopathological dysfunctions underlying mental disorders have been recognized in the present study with the PFL-RS. This instrument seems promising to inform in a specific way treatments strategies and goals, specifically concerning psychotherapy. Notwithstanding, further research is needed in order to confirm validity, sensitivity and reliability of this instrument.

Mentalization-based treatment for psychotic disorder: protocol of a randomized controlled trial

BACKGROUND

Many patients with a non-affective psychotic disorder suffer from impairments in social functioning and social cognition. To target these impairments, mentalization-based treatment for psychotic disorder, a psychodynamic treatment rooted in attachment theory, has been developed. It is expected to improve social cognition, and thereby to improve social functioning. The treatment is further expected to increase quality of life and the awareness of having a mental disorder, and to reduce substance abuse, social stress reactivity, positive symptoms, negative, anxious and depressive symptoms.

METHODS/DESIGN

The study is a rater-blinded randomized controlled trial. Patients are offered 18 months of therapy and are randomly allocated to mentalization-based treatment for psychotic disorders or treatment as usual. Patients are recruited from outpatient departments of the Rivierduinen mental health institute, the Netherlands, and are aged 18 to 55 years and have been diagnosed with a non-affective psychotic disorder. Social functioning, the primary outcome variable, is measured with the social functioning scale. The administration of all tests and questionnaires takes approximately 22 hours. Mentalization-based treatment for psychotic disorders adds a total of 60 hours of group therapy and 15 hours of individual therapy to treatment as usual. No known health risks are involved in the study, though it is known that group dynamics can have adverse effects on a psychiatric disorder.

DISCUSSION

If Mentalization-based treatment for psychotic disorders proves to be effective, it could be a useful addition to treatment.

Written on the Face: Self- and Expert-Rated Impairments in Personality Functioning Are Differently Related to the Expression of Disgust Toward an Interviewer

Although current theories suggest that impairments in personality functioning are at the core of personality pathology, there is a lack of research on how these impairments play out behaviorally. The aim of the present study was to investigate disgust expressions as indicators of personality dysfunction. Facial expressions were investigated in a sample of 78 female participants during an in-depth clinical interview and coded with the Facial Action Coding System. Personality dysfunction was assessed with self- and expert ratings. By applying a joint regression analysis, the authors found that disgust expressions toward the interviewer were positively associated with expert ratings but negatively associated with self-ratings. In other words, disgust expressions were indicative of an underestimation of personality dysfunction by participants as compared with experts. This suggests that interactional expressions of disgust might be a behavioral marker of personality dysfunction when individuals are unaware of or deny impairments.

[Standardization of the German 16-item short version of the Inventory of Personality Organization (IPO-16)]

Standardization of the German 16-item short version of the Inventory of Personality Organization (IPO-16).

OBJECTIVES

The 16-item short version of the Inventory of Personality Organization (IPO-16) is a self-report measure assessing the severity of personality dysfunction. This study provides representative norms and determines the smallest real difference value for the IPO-16.

METHODS

Standardization of the IPO-16 was based on a representative survey among the German general population (N = 2502). Retest reliability and the smallest real difference were assessed in a separate longitudinal online survey, whereby participants completed the IPO-16 three times at time intervals of 2 months (N = 495).

RESULTS

The average IPO-16-mean score in the general population was 1.87. The influence of age and sex was small, albeit statistically significant.We therefore developed sex- and age-specific norms. The average retest reliability across 2 months was .85, and the smallest real difference was 0.66.

CONCLUSIONS

The IPO-16 is a well-validated, and now standardized, screening instrument for the assessment of severity of personality dysfunction. It can be recommended for use in research and practice.

Tailoring psychotherapy in patients with personality disorders: Matching the level of psychological strengths to the level of stabilizing versus destabilizing psychotherapy

BACKGROUND

Clinical evidence suggests that patients high on psychological strengths profit more from destabilizing psychotherapy, whereas patients low on strengths profit more from stabilizing psychotherapy. This matching hypothesis was tested.

METHODS

This quasi-experimental study was conducted between 2003 and 2008 in 735 patients with personality disorders from 6 psychotherapy centers in the Netherlands. Patients were assigned to different levels of stabilizing and destabilizing psychotherapies. Levels of psychological strengths were measured. We used multilevel modeling to estimate outcome at 12 months after baseline. The propensity score controlled for initial differences at baseline.

RESULTS

The findings show that destabilizing psychotherapies have slightly better outcomes than stabilizing psychotherapies. Patients high on psychological strengths improve slightly more than patients low on psychological strengths. The observed interaction effect contradicted our hypothesis.

CONCLUSION

The results imply that destabilizing psychotherapies can be considered as first treatment option for patients both high and low on psychological strengths.

The effectiveness of short- and long-term psychotherapy on personality functioning during a 5-year follow-up

BACKGROUND

Only few randomized trials comparing sustained effects of short- and long-term psychotherapies in personality functioning are available. In this study we compared the effects of two short-term therapies and long-term psychodynamic psychotherapy on patients' personality functioning during a 5-year follow-up.

METHODS

Altogether 326 patients of the Helsinki Psychotherapy Study, with anxiety or mood disorder, were randomly assigned to either short-term psychotherapy of about six months (solution-focused therapy (SFT, n=97) or short-term psychodynamic psychotherapy (SPP, n=101)), or to long-term psychodynamic psychotherapy (LPP, n=128), lasting on average three years. Outcomes in personality functioning (i.e., self-concept, defense style, interpersonal problems, and level of personality organization) were assessed five to seven times using, respectively, questionnaires (SASB, DSQ, IIP) and interview (LPO) during the 5-year follow-up from randomization.

RESULTS

Personality functioning improved in all therapy groups. Both short-term therapies fared better than LPP during the first year of follow-up, by faster improvement in self-concept and decrease in immature defense style. SFT also showed more early reduction of interpersonal problems. However, LPP thereafter showed larger and more sustained benefits than SFT and SPP, through greater changes in self-concept. Additionally, LPP outperformed SFT at the end of the follow-up in IIP and LPO, after adjustment for auxiliary treatment. No differences were noted between the short-term therapies at any measurement point.

LIMITATIONS

Auxiliary treatment was used relatively widely which limits generalization to exclusive use of short- or long-term therapy.

CONCLUSIONS

LPP seems to be somewhat more effective than short-term therapies in facilitating longterm changes in personality functioning.

Dimensions of the operationalized psychodynamic diagnosis system that predict long-term outcome after inpatient psychotherapy

BACKGROUND/AIMS

To determine whether the Operationalized Psychodynamic Diagnosis (OPD) system can be useful in predicting patient outcome in the long term.

METHODS

OPD was assessed by the therapists prior to and after inpatient treatment. Patients completed psychometric scales at the start and completion of psychosomatic-psychotherapeutic inpatient treatment and at the follow-up. Outcome was defined by the general factor emerging from a principal component analysis of the Brief Symptom Inventory, Hospital Anxiety and Depression Scale and Inventory of Interpersonal Problems at katamnesis, representing individual differences in general distress.

RESULTS

Several dimensions of the OPD system proved to be predictors of general distress at the follow-up in 253 former inpatients. Negative predictors of long-term outcome were the high internal impediments to change, namely high secondary gains from illness and also less integrated structural abilities. Positive OPD predictors of long-term outcome were the treatment success achieved at the end of inpatient psychotherapy in changing the illness concept towards a psychological understanding of symptoms, lower levels of complaints and a higher functional level. Also the achieved level of awareness for the individual maladaptive behavioral pattern is predictive of a favorable long-term outcome.

CONCLUSIONS

The results provide evidence for the clinical relevance and the predictive value of OPD. © 2014 S. Karger AG, Basel.

Association between level of personality organization as assessed with theory-driven profiles of the Dutch Short Form of the MMPI and outcome of inpatient treatment for personality disorder

The association between level of personality organization as assessed by theory-driven profile interpretation of the MMPI (Hathaway & McKinley, 1943) Dutch Short Form and treatment outcome was investigated in a naturalistic follow-up study among 121 psychotherapy inpatients who had been treated for their severe personality pathology. Treatment outcome was measured with the Brief Symptom Inventory (De Beurs & Zitman, 2006). Personality organization was associated with severity of psychopathology at baseline, the end of treatment, and 36 months after baseline. At 36 months after baseline, all patients except those with the high-level borderline organization profile and the psychotic borderline profile maintained their improvement. Contrary to expectations, (a) personality organization did not differentiate between patients with successful and unsuccessful out-comes, and (b) patients with a neurotic personality organization did not respond better than those with a borderline personality organization. Because of the small N, conclusions are tentative.

Social cognition and levels of personality organization in patients with somatoform disorders: a case-control study

Social cognition and its association with level of personality organization (PO) were examined in 163 patients with severe somatoform disorders (SFDs) and 151 psychiatric (PSA) control patients. Social cognition was measured with the Social Cognition and Object Relations Scale, which assessed both affective and cognitive facets of social cognition. Levels of PO were assessed using theory-driven profiles of the Dutch Short Form of the Minnesota Multiphasic Personality Inventory (MMPI). The SFD patients exhibited impairments in the cognitive facets of social cognition but not more so than the PSA controls. The results for the affective aspects indicated that the SFD patients exhibited lower levels of emotional investment yet higher affect tone in interactions than the PSA controls. In contrast to the control group, level of PO was not associated with social cognition in SFD. Together, the results indicated that impairments in complexity of mental representations are not specific to SFD patients, yet impairments in emotional investment may be specific to SFD.

Levels of personality functioning and their association with clinical features and interpersonal functioning in patients with personality disorders

Recently, the DSM-5 Personality and Personality Disorders Work Group has proposed a multiple level approach toward the classification and diagnosis of personality disorders (PDs), with the first level entailing a rating of impairments in levels of personality functioning. Although a number of measures that assess levels of personality functioning have been validated, given its prominent status in the DSM-5 proposal and contemporary theories of personality pathology, the Work Group has called for more research in this area (e.g., Bender, Morey, & Skodol, 2011). In response to this call, this study investigates the relationship between two major, well-validated dimensional measures of levels of personality functioning, that is, the Differentiation-Relatedness Scale (DR-S; Diamond, Blatt, Stayner, & Kaslow, 1991), as scored on the Object Relations Inventory (ORI; Blatt, Wein, Chevron, & Quinlan, 1979), and the Inventory of Personality Organization (IPO; Lenzenweger, Clarkin, Kernberg, & Foelsch, 2001), a self-report instrument, and their relationship with different measures of clinical and interpersonal functioning in 70 patients with a PD. First, results showed that higher levels of differentiation and relatedness of descriptions of self and significant others, and of the self in particular, were negatively related to indices of personality functioning as assessed by the IPO. Lower levels of personality functioning, as measured with both the DR-S and the IPO, were positively related to severity of depression, symptomatic distress, self-harm, and interpersonal problems. Finally, results showed that the DR-S and the IPO independently predicted clinical features and interpersonal functioning. Hence, this study lends further support for the concurrent and predictive validity of the DR-S and the IPO in assessing levels of personality functioning. However, more research concerning the validity of these measures in assessing levels of personality functioning is needed. Suggestions for further research are formulated.
