Unresolved attachment and identity diffusion in adolescence

This study examined the severity of unresolved attachment underlying adolescent identity diffusion. Our sample consisted of 180 inpatient adolescents aged 14 to 18 years (77% female, M age = 15.13, SD = 1.35; 23% male, M age = 14.85, SD = 1.41) and 84 age-matched non-clinical adolescents (52% female, M age = 16.14, SD = 1.21; 48% males, M age = 15.98, SD = 1.07). We used the Adult Attachment Projective Picture System (AAP) interview to assess attachment representations and the Assessment of Identity Development in Adolescence (AIDA) questionnaire to evaluate the severity of identity diffusion. Our results demonstrate a higher amount of unresolved attachment and identity diffusion in the patient sample than in the control sample. Furthermore, patients with an unresolved attachment status scored higher on identity diffusion than those with no unresolved attachment pattern. Interestingly, this was not found in the control group. Furthermore, patients with a greater severity of unresolved attachment showed the highest maladaptive identity development scores. Psychotherapeutic interventions integrating attachment-related aspects might be useful to treat young people with identity diffusion.

Changes in Attachment Representation and Personality Organization in Transference-Focused Psychotherapy

OBJECTIVE

The aim of this article was to construct an empirical bridge between object relations theory and attachment theory by investigating how researchers in both traditions have contributed to understanding and assessing identity diffusion (a keystone of personality pathology) and object relations in patients with borderline personality disorder during 1 year of transference-focused psychotherapy (TFP).

METHODS

The Adult Attachment Interview (AAI) and the Structured Interview of Personality Organization (STIPO) were administered to patients (N=104, all women) before and after 1 year of treatment. This study was part of a randomized controlled trial in which 104 patients with borderline personality disorder were randomly assigned to receive either TFP (a manualized, structured psychodynamic treatment approach) or treatment by experienced community psychotherapists. Changes on the AAI in attachment representations, narrative coherence, and reflective function were examined for their associations with changes on the STIPO in identity, object relations, and aggression.

RESULTS

Patients who shifted from disorganized (unresolved) to organized attachment on the AAI after 1 year of TFP (but not treatment by experienced community psychotherapists) showed hypothesized improvements in domains of personality organization on the STIPO, including identity, object relations, and aggression. Those who did not change from disorganized (unresolved) to organized attachment improved only in the domain of aggression.

CONCLUSIONS

These findings highlight the centrality of identity diffusion to borderline personality disorder pathology and the importance of targeting it in treatment. Furthermore, the results suggest that identity may be indexed by measures of attachment security, narrative coherence, and personality organization.

Operationalizing intimacy and identity aspects of personality functioning in relation to personality disorder in adolescents

According to dimensional models of personality pathology, deficits in interpersonal (intimacy and empathy) and self (identity and self-direction) function (Criterion A) are core to all personality disorders. These aspects of personality functioning (Criterion A) have seldom been evaluated for how they might relate to one another in the context of personality pathology in adolescents. Moreover, the use of performance-based measures to evaluate aspects of Criterion A function remains an untapped resource. Therefore, the present study aimed to evaluate relations between two features of Criterion A, maladaptive intimacy and maladaptive (or diffused) identity, in adolescence. For intimacy, we leverage a performance-based approach to studying intimacy, operationalized in a developmentally relevant way (perceived parental closeness). For identity, we rely on a validated self-report measure of identity diffusion. We examined the relationship between these features with each other and their relations with borderline features. Additionally, we explored whether identity diffusion mediated the expected relationship between perceived parental closeness and borderline features. We hypothesized that greater distance in perceived parental closeness would be associated with higher levels of borderline features, as well as higher levels of identity diffusion, and that identity diffusion would account for the relationship between intimacy and personality pathology. The sample included 131 inpatient adolescents (M _age = 15.35, 70.2% female). Results indicated that intimacy, operationalized as perceived parental closeness, with both mothers and fathers was significantly associated with levels of identity diffusion and borderline features. In addition, greater feelings of closeness with parents were associated with lower severity of borderline features via healthier identity function. Implications of the results, limitations, and future directions are discussed.

Identity and Personality Pathology: A Convergence Across the DSM-5 Personality Disorder Model and the Alternative Model for Personality Disorders

Long-standing theory regarding personality pathology as well as the recently proposed DSM-5 Alternative Model for Personality Disorders (AMPD) posit that self/identity problems are a hallmark feature cutting across forms of personality pathology. With emergence of the AMPD, researchers have started to focus empirical investigations on identity pathology as a transdiagnostic factor across personality pathology. The current study investigated identity pathology across indicators of personality pathology from both the current categorical perspective (DSM-5 PD) and the dimensional perspective in the AMPD. Identity diffusion and low self-concept clarity were correlated with all PD feature scales and all maladaptive personality dimension scales. Regression analyses revealed most indicators of personality pathology were significant correlates of identity diffusion and low self-concept clarity. Borderline and Avoidant PD feature scales and Negative Affectivity and Detachment maladaptive personality dimension scales emerged as the strongest correlates of identity pathology. The role that identity pathology plays in personality pathology is highlighted.

Explicit and Implicit Measures of Identity Diffusion in Adolescent Girls With Borderline Personality Disorder

The present study is the first to examine both the implicit and explicit self-concept of identity diffusion in a sample of adolescent patients with borderline personality disorder (BPD). A clinical sample of adolescent girls with diagnosed BPD (N = 30; M age = 15.9 years) and a sample of girls with a healthy personality development (N = 33; M age = 16.6 years) completed an implicit association test (IAT) that was adjusted to identity diffusion, the core of BPD. Common domains of child and adolescent psychopathology and core components of BPD were assessed using self-reports on the Strengths and Difficulties Questionnaire (SDQ), the Borderline Personality Features Scale for Children-11 (BPFSC-11) and the Assessment of Identity Development in Adolescence (AIDA). BPD patients scored significantly higher on explicit measures of borderline pathology than girls with a healthy personality development. A crucial finding for this study was that girls with BPD had a significantly lower implicit preference for stability than their counterparts in the control group. Moreover, explicit measures of borderline personality pathology were significantly correlated with an implicit measure of identity diffusion, the core of BPD. However, when looking at the predictive ability of implicit and explicit measures, only explicit identity diffusion was significantly associated with borderline features. Our data suggests that adolescent girls with BPD differ from healthy individuals not only in their conscious representation but also in their implicit representation of the self with regard to BPD related characteristics, which further advances the need for the identification of at-risk adolescents.

Identity Diffusion as the Organizing Principle of Borderline Personality Traits in Adolescents-A Non-clinical Study

Growing evidence shows that diagnosing and treating borderline personality disorder (BPD) is of high relevance for affected youths. Although identity crisis is part of the normative developmental process, identity diffusion is a potential candidate for being an appropriate concept in further developing screening tools and interventions for BPD treatment in adolescence. We hypothesized that severity of borderline traits (as indicated by the strength of their associations with identity diffusion) would be negatively associated with non-clinical adolescents' endorsement of borderline features' presence. We also hypothesized that identity diffusion had a central role in the network of borderline personality traits and could be conceived of as a latent organizing principle of borderline personality disorder. In our study, 169 non-clinical adolescents (81 girls and 88 boys; M _age = 15.38; SD_age = 1.52) filled out self-report measures of borderline personality features and identity diffusion. According to our results, having strong feelings and interpersonal sensitivity were the two most endorsed borderline personality features. Borderline personality features were positively correlated with identity diffusion. The more severe a borderline personality feature was, the less relevant it was for non-clinical adolescents. According to a network analysis, identity diffusion was the most central and least redundant element of the network of borderline personality traits. Results are discussed from a clinical point of view, further encouraging professionals to use identity diffusion screening tools to detect BPD in adolescence.

[TransIdentity - Identity Development Among Adolescent Trans*people]

TransIdentity - Identity Development Among Adolescent Trans*people Identity development is one of the most important developmental tasks of adolescence. Adolescents whose gender identity does not correspond to the gender assigned at birth (trangender people) are also faced with this challenge, as are cis-gender adolescents of the same age. This study is the first to examine the personality function of identity in transgender adolescents. Based on the self report of a population of 69 adolescents from the outpatient unit for gender dysphoria the extent of identity diffusion measured by AIDA (Assessment of Identity Development in Adolescence) was compared with the values of the normative sample consisting of German-speaking pupils. Both the overall construct of identity diffusion and the areas of continuity and coherence showed average values in the examined young people, which speaks against pathological identity development. Nevertheless, identity diffusion was found in over a third (36 %). Most notably the aspect of stabilising relationships and roles was above average, which suggests that positive role identification from the areas of culture, family and body-self is present to a lesser extent than in the norm sample. The identity-stabilizing feeling of social anchoring appears to be impaired in the young transidents studied.

Psychotic Personality Structure

This article discusses the concept of psychotic personality organization. I relate psychotic personality organization to observations and speculations about psychotic transferences and to behavioral developments during the treatment of chronically psychotic patients (particularly those with schizophrenia). The overwhelming theoretical perspectives used are twofold: (1) object relations theory and (2) a model integrating neurobiological advances in the study of psychosis with contemporary psychodynamic perspectives.

Associations among parental and romantic attachment, personality disorder symptoms, and physical health

The relations of parental and romantic attachment with physical health symptoms and the mediating role of personality disorder symptoms in those relations were examined in an online survey of US young adults. Latent class analysis identified two groups: occasionally sick and healthier. Insecure attachment was related to being occasionally sick and to personality disorder symptoms (poor reality testing, primitive defenses, and diffused identity). Primitive defenses/identity diffusion mediated relations between insecure parental attachment and physical symptoms. Maternal and paternal attachment each provided unique information about these relations. Romantic attachment was not associated with physical symptoms after adjusting for parental attachment and personality disorder symptoms.

[Identity Diffusion Among Adolescents - Validation of the Inventory of Personality Organization in a Clinical Adolescent Sample (IPO-A)]

Identity Diffusion Among Adolescents - Validation of the Inventory of Personality Organization in a Clinical Adolescent Sample (IPO-A) The main objective of the current study was to analyze the psychometric properties of the German version of the Inventory of Personality Organization for Adolescents (IPO-A). The instrument consisting of 91 items is based on the theoretical structural model by Kernberg and investigates the severity of identity diffusion, reality testing and defense mechanisms in order to determine the level of personality organization. The factor structure, the internal consistency and the convergent validity was measured among 144 inpatients aged between 13 and 18 years drawn from the Child and Adolescent Psychiatry of the University Clinic of Cologne. The investigation revealed a five factor structure: identity diffusion, reality testing, defense mechanisms, aggression and instability of goals. Moreover, testing the psychometric properties of the instrument showed a high internal consistency and meaningful significant correlations with well-validated youth self-report instruments assessing personality pathology and psychopathology. Thus, the results indicate that the IPO-A can be considered to be a reliable instrument that measures personality organization and identity diffusion in adolescents with personality disorders.

Self-other disturbance in borderline personality disorder: Neural, self-report, and performance-based evidence

Individuals with borderline personality disorder (BPD) display an impoverished sense of self and representations of self and others that shift between positive and negative poles. However, little research has investigated the nature of representational disturbance in BPD. The present study takes a multimodal approach. A card sort task was used to investigate complexity, integration, and valence of self-representation in BPD. Impairment in maintenance of self and other representations was assessed using a personality representational maintenance task. Finally, functional MRI (fMRI) was used to assess whether individuals with BPD show neural abnormalities related specifically to the self and what brain areas may be related to poor representational maintenance. Individuals with BPD sorted self-aspects suggesting more complexity of self-representation, but also less integration and more negative valence overall. On the representational maintenance task, individuals with BPD showed less consistency in their representations of self and others over the 3-hr period, but only for abstract, personality-based representations. Performance on this measure mediated between-groups brain activation in several areas supporting social cognition. We found no evidence for social-cognitive disturbance specific to the self. Additionally, the BPD group showed main effects, insensitive to condition, of hyperactivation in the medial prefrontal cortex, temporal parietal junction, several regions of the frontal pole, the precuneus and middle temporal gyrus, all areas crucial social cognition. In contrast, controls evidenced greater activation in visual, sensory, motor, and mirror neuron regions. These findings are discussed in relation to research regarding hypermentalization and the overlap between self- and other-disturbance.

On identity: from a philosophical point of view

BACKGROUND

The term "identity" has a much longer tradition in Western philosophy than in psychology. However, the philosophical discourse addresses very different meanings of the term, which should be distinguished to avoid misunderstandings, but also to sharpen the key meanings of the term in psychological contexts. These crucial points in the philosophical concepts of identity in the sense of singularity, individuality, or self-sameness may structure the ongoing discussion on identity in psychiatric diagnoses (as in DSM-5, Child Adolesc Psychiatry Ment, this issue, 2013), in psychology, psychoanalysis, but also neuroscience and neurophilosophy (Child Adolesc Psychiatry Ment, this issue, 2013).

METHOD

The concept of identity is subjected to a systematic philosophical analysis following some milestones in its history to provide a background for recent discussions on identity in psychiatry and psychology.

RESULTS

The article focuses first on the philosophical core distinctions of identity in the different meanings to be addressed, second, briefly on some of the diverse psychological histories of the concept in the second half of the 20th century. Finally some reflections are presented on borderline personality disorder, considered as a mental disorder with a disturbance or diffusion of identity as core feature, and briefly on a newly developed instrument assessing identity development and identity diffusion in adolescence, the AIDA that is also presented in the special issue of this journal (Child Adolesc Psychiatry Ment, this issue, 2013).

CONCLUSION

As a conclusion, different points of view concerning identity are summarized in respect to treatment planning, and different levels of description of identity in phenomenology, philosophy of mind, cognitive science, and social science and personality psychology are outlined.
