“…According to psychodynamic theory, a patient with a lower structural integration shows symptom intensification and a lower therapy response. The scale "self-perception" combines aspects of the self with structural skills of emotional regulation (51). In our participants, we detected a high correlation with somatization, anxiety, and depression.…”

Personality Structure and Attachment in Bipolar Disorder

et al. 2020

Background: An impairment of self and interpersonal functioning has an impact on coping strategies, regulation of affect and stress. Little is known so far about the impairment of personality functioning in patients with bipolar disorder (BD). The aim of this study is to assess the effects of personality structure and attachment in BD patients on the symptom burden. Methods: Forty-six patients with the diagnosis of BD were assessed by the 12-item Operationalized Psychodynamic Diagnosis Structure Questionnaire (OPD-SQS), the short version of Experience in Close Relationship-revised (ECR-R-D), and the Brief Symptom Inventory-18 (BSI 18) to determine the level of personality functioning, attachment patterns, and symptom load. Results: We observed positive correlations between personality difficulties, insecure attachment, and symptom load in patients with BD. A low level of structural integration and an insecure attachment style in patients with BD were accompanied by a significantly higher symptom load (r = 0.66, p ≤ 0.01). Interestingly, there were no significant differences in the structural integration (T(1.44) = −0.93, p = 0.357) and in the attachment style attachment related avoidance: (T(1,44) = 1.50, p = 0.140); attachment related anxiety (T(1,44) = −0.781, p = 0.439) of study participants with BD when compared to the normative value of the general population. Limitations: Our limitations are the small sample size of our group and the lack of a control group. Conclusion: In general, our results suggest that there is a link between personality structure and affective dynamics including depressive, anxiety, and somatization symptoms in BD. These findings underline the increasing importance of assessing personality structure and attachment for diagnosis and treatment planning of BD.

“…If the results of this study are confirmed, the OPD-SQ could be applied as a useful and practical additional tool for eating disorders. In this context, the application of the short version of the questionnaire (OPD-SQS), which has been developed and validated for screening (Ehrenthal et al, 2015; Obbarius et al, 2018), may also be appropriate. However, this needs to be investigated in future studies.…”

“…Psychometric information was gathered electronically with smartphones along with the clinical routine assessment between 2012 and 2017. Data from N = 1235 patients was gathered during this period of time, see Obbarius et al (2018) for a detailed description of patient characteristics. A subset of N = 60 patients were found to have AN (typical or atypical) or BN and were included in this study.…”

BackgroundDifferentiation between purging type (AN-P) and restricting type (AN-R) is common in anorexia nervosa (AN) and relevant for clinical practice. However, differences of personality pathology in eating disorders (ED) and their subtypes, which can be captured by the operationalized psychodynamic diagnosis (OPD) system, have not been systematically investigated to date.ObjectivesThe aim of this study was to explore differences in personality structure between the subtypes of AN and bulimia nervosa (BN) using the OPD structure questionnaire (OPD-SQ). In addition, the ability of the instrument to support the classification of eating disorders was examined.Materials and MethodsWe conducted a retrospective, exploratory study in a subset sample of a larger validation study. The OPD-SQ had been collected from n = 60 patients with AN or BN. Patients were assigned to the ED groups by clinical assessment. Statistical analyses included multivariate analysis of variance (MANOVA) and discriminant analysis.ResultsDifferences between ED groups were observed on 5 OPD-SQ main scales and 9 subscales, as well as on the global scale. AN-P patients demonstrated the lowest personality structure on most of the main scales and subscales, whereas AN-R patients showed a higher personality structure level as compared to both BN and AN-P patients. The OPD-SQ scales with the largest differences include self-perception, object perception, and attachment to internal objects. Discriminant analysis resulted in satisfactory assignment to ED groups by OPD-SQ subscales.ConclusionsPersonality structure was found to be less developed in patients with BN and AN-P as compared to patients with AN-R. Although the results have to be proven in larger prospective studies, these results suggest that the OPD-SQ may be used to support the clinical assessment and classification in patients with EDs.

“…It captures 3 subdomains of personality functioning, including self-perception, interpersonal contact and relationship model. In a sample of psychosomatic out- and inpatients, the internal consistency of the total (sum) score was high (Cronbach’s α = 0.89), and the general factor explained roughly 70% of the common variance [46].…”

A Common Metric for Self-Reported Severity of Personality Disorder

Introduction: Dimensional models of personality disorders (PD) in the DSM-5 and ICD-11 share a focus on impairments in self and interpersonal functioning to represent the general features and severity of PD. This new perspective has led to the development of numerous measures for assessing individual differences in PD severity. While this improves choices for researchers and practitioners, it also poses the challenge of an increasing lack of standardization. Objective: The aim of this study is to establish a common metric across 6 widely used self-report measures of PD severity using item response theory models. Methods: 849 participants completed a survey including the Inventory of Personality Organization-16-item version (IPO-16), the Level of Personality Functioning Scale-Brief Form 2.0, the Level of Personality Functioning Scale-Self-Report, the Operationalized Psychodynamic Diagnosis-Structure Questionnaire Short Form, the Personality Inventory for DSM-5-Brief Form Plus and the Standardized Assessment of Severity of Personality Disorder (SASPD). We fitted exploratory multidimensional graded response models and used bifactor rotation to extract a general factor across measures. Factor scores were linked to representative T scores using data from a representative survey of 2,502 participants who completed the IPO-16. Results: When using bifactor rotation in a 7-factor model, all items loaded positively on the general factor, and the general factor explained 65.5% of the common variance. With the exception of the SASPD, all measures provided highly discriminating items (factor loadings > 0.70) for measuring the general factor and reached an acceptable reliability (> 0.80) across a wide range of the latent continuum. We constructed a crosswalk table linking total scores of the 6 measures to each other and to representative T scores. Conclusions: Our results suggest that 6 different self-report measures of the severity of PD capture a strong common factor and can therefore be scaled along a single latent continuum. Our results may facilitate instrument-independent assessment of severity of PD and increase comparability across studies.

Abstract: The OPD-SQS seems to be appropriate for screening of personality dysfunction. However, other aspects of psychopathology are gathered in addition. Therefore, further investigation of the patients' personality structure such as an OPD interview may be added in clinical settings.
