Identity disturbance in adolescence: associations with borderline personality disorder

The Role of Identity Formation in Explaining Dynamic Risk Factors Among Incarcerated Emerging Adults

Emerging adulthood is increasingly acknowledged as a discrete developmental stage with its own specific challenges. Identity formation is a major development task during emerging adulthood, yet its relationship to dynamic risk factors remains unclear. Therefore, this study aimed to investigate the association between identity diffusion and dynamic risk factors in a sample of young, incarcerated adults. The study involved 99 males between ages of 18 and 23, serving custodial sentences in four Lithuanian prisons. Zero-order correlations showed significant relationships between the length of the current sentence and psychopathology, and the number of previous sentencing occasions and dynamic risk factors. The results of hierarchical regression analysis revealed that identity diffusion explained dynamic risk factors above and beyond criminal history, protective factors, and psychopathology. These findings support a developmentally informed approach to correctional treatment, suggesting that interventions targeting identity diffusion could be suitable and beneficial for young, incarcerated adults. Limitations and future directions are discussed.

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.

Identity Pathology and Emptiness as Novel Predictors of Suicidal Ideation

Emptiness and identity pathology are understudied clinical constructs that overlap, co-occur, and predict suicidal ideation (SI). However, specific risk pathways have yet to be formally tested.

AIM

We examined whether identity pathology was indirectly associated with future SI via emptiness, and tested impulsivity and emotion dysregulation as moderators.

METHODS

Participants (N = 251) completed baseline questionnaires assessing SI, borderline personality disorder symptoms, emotion dysregulation, and impulsivity, and SI 2 months later.

RESULTS

Identity pathology was indirectly associated with future SI via emptiness, controlling for baseline SI (β = 0.15, Bootstrap 95% CI = [0.06, 0.24]). There was a two-way interaction between emptiness and both poor use of emotion regulation strategies (β = 0.06, p < 0.001) and impulsive lack of premeditation (β = 0.09, p = 0.03) predicting SI.

CONCLUSION

Those with greater identity pathology were more likely to experience emptiness, which was in turn associated with future SI. Participants who felt empty were also more likely to experience SI when they also reported an inability to use emotion regulation strategies and a tendency to act without considering the consequences. We provide preliminary support for an untested risk pathway for SI, highlighting the need to further study these important experiences.

Unraveling the Association: How Identity Mediates the Impact of Childhood Trauma on Criminal Behavior

Previous research has consistently linked childhood trauma to criminal behavior in adulthood, yet the mechanisms driving this association remain poorly understood. This study investigated whether identity mediates this relationship, focusing on three identity constructs: consolidated identity, disturbed identity, and lack of identity. Criminal behavior was operationalized as a dichotomous variable, distinguishing between 103 community participants (53.9%) and 88 forensic psychiatric patients (46.1%) in a sample of 191 male participants (Mage = 39.82, SDage = 14.14). Mediation analysis was conducted using PROCESS macro model 4, controlling for age and overall personality dysfunction. The results demonstrated that childhood trauma was associated with adult criminal behavior. Additionally, childhood trauma was positively associated with lack of identity but showed no significant effect on consolidated and disturbed identity. Likewise, lack of identity was the only identity variable associated with criminal behavior and emerged as the sole mediator between childhood trauma and criminal behavior. These findings underscore the important role of identity, particularly the lack of identity, in understanding pathways to criminal behavior. Interventions aimed at strengthening individuals' sense of self may help mitigate criminal tendencies in individuals with a history of childhood trauma, though longitudinal research is needed to further validate these findings.

Unified Protocol vs Mentalization-Based Therapy for Adolescents With Borderline Personality Disorder: A Randomized Controlled Trial

BACKGROUND

Despite several treatments, e.g., mentalization-based therapy (MBT) and Unified Protocol (UP), being adapted to treat adolescents with borderline personality disorder (BPD), there exists a dearth of literature regarding their relative efficacy. In this study modified forms of MBT and UP - MBT-A and UP-A respectively-were compared in their ability to reduce borderline symptoms in a sample of 91 Iranian adolescents (two-thirds female) with a BPD diagnosis.

METHODS

Individuals randomly allocated to one of two treatment groups, MBT-A (N = 45) or UP-A (N = 46) were followed up across 36 months following treatment. A MIXED ANCOVA was applied to compare the effectiveness of these interventions in reducing severity of borderline symptoms (the primary outcome), impulsivity, self-harm, emotion dysregulation and anger (secondary outcomes). The trial was retrospectively registered at IRCT20231106059970N1.

RESULTS

Both primary outcomes and secondary outcomes decreased significantly following both MBT-A and UP-A. In comparison with MBT-A, UP-A was more effective in reducing emotional dysregulation, but levels of remission declined progressively up to 36 months of follow-up following both treatments.

CONCLUSIONS

UP-A appears to be more effective than MBT-A in reducing emotional dysregulation in adolescents with BPD, despite being a shorter and less intensive treatment. An important caveat is that the treatment induced changes were largely limited to the emotion dysregulation aspect of BPD; other aspects (interpersonal and identity disturbances) were largely unchanged by either treatment.

Identity and Personality Pathology in Adult Forensic Psychiatric Patients and Healthy Controls

Since the publication of the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), identity impairment has become a diagnostic criterion for all personality disorders. The current study examined the occurrence of identity dimensions, clinically relevant identity impairments and personality pathology, and associations between these constructs in 92 forensic patients and 139 healthy controls. Patients showed higher levels of almost all identity dimensions, identity impairments, personality disorders, and almost all maladaptive personality traits than controls. Various identity dimensions were associated with consolidated identity as well as identity impairments in both groups. Both patients and controls with high ruminative exploration and identity malfunctioning showed more personality pathology. Different associations between identity functioning and particularly antisocial and borderline personality disorder showed to be stronger in patients than in controls. Our results highlight the importance of identity impairment as a crucial criterion to assess and treat personality pathology in forensic patients.

Attachment and body representations in adolescents with personality disorder

BACKGROUND

Attachment theory has served as an influential framework for understanding psychopathology, partly due to reliable assessment methodology. The influence of insecure attachment on attitudes toward the body and the impact this might have for the development of psychopathology is however less well elucidated.

METHOD

A total of 123 adolescents (35 with borderline personality disorder or BPD, 25 with other personality disorders [OPD] and 63 comprising a normative control group) were interviewed with the Adult Attachment Interview (AAI) and the Mirror Interview (MI). The MI questions respondents about how they feel about their bodies, as they look in the mirror.

RESULTS

The AAIs from the Borderline group were predominantly insecure-preoccupied and unresolved. These adolescents had significantly lower levels of a positive and integrated sense of self and body than the other groups. Regression results revealed a high loving relationship with fathers, low involving anger with father, high coherence of mind, slight derogation of mother & low levels of unresolved loss uniquely and additively predicted 55% of variance in the summary score assigned to MI responses, that is, the summary score for a Positive and Integrated Body Representation (PIBR).

CONCLUSION

Unfavorable attachment experiences and current states of mind regarding attachment may give rise to problems with establishing PIBRs, and thus play a role in the development of psychopathology, especially BPD.

Identity Formation in Individuals between 16 and 25 Years Old with Borderline Personality Disorder

Background/Objectives: Identity disruption is a key feature of borderline personality disorder (BPD), characterized by disturbances in self-image. This study aimed to use the Dimensions of Identity Development Scale (DIDS) in a population aged 16-25, to assess differences in identity status and correlations with BPD features as well as whether a correlation exists between the BPD features, the scores obtained on the DIDS and the scores of the different dimensions of this disorder. Methods: We analyzed data from 132 individuals: 44 with BPD using the Diagnostic Interview for Borderline-Revised (DIB-R). Statistical analyses included quantile regression to determine the differences in the DIDS after adjusting for confounding factors identified during group comparisons and Spearman correlation between the DIDS, the BPD features and the DIB-R. Results: Results indicated significantly lower DIDS scores in the BPD group, particularly in commitment making, exploration breadth (EB), identity with commitment (IM) and ruminative exploration (RE). After adjusting, only EB differs significantly between the two groups. All dimensions of the DIDS except for the exploration in depth (ED) are correlated with BPD features. Significant correlations could be demonstrated between cognitive dimension and ED, between the total DIDS and the number of suicide attempt (SA) and between the IM and the number of SA. Conclusions: Our clinical sample showed distinct identity formation compared to controls, with a lower EB associated with BPD. RE correlated with BPD, suggesting that the individuals engage in repetitive exploratory processes. SA was negatively associated with overall identity development and commitment, indicating impulsive behaviors in BPD intersect with identity struggles.

Awareness of Narrative Identity Questionnaire (ANIQ) in Early Adolescents: Psychometric Evaluation and Association with Features of Personality Disorder

Identity formation is central to adolescent development. Challenges in establishing a stable sense of self is associated with maladaptive identity function, which has been recognized as a core feature of personality pathology. The narrative identity framework offers a unique lens to garner salient information about one's sense of self. The Awareness of Narrative Identity Questionnaire (ANIQ) is a self-report measure of narrative identity validated in adults but is yet to be validated in adolescents. The current study aimed to conduct the first psychometric evaluation of the ANIQ in a sample of 205 youth aged 10-14 years (M = 12.1 ± 1.06 years; 50.7% female; 73.7% Hispanic) recruited from a public charter school. Results confirmed the four-factor structure of the ANIQ and showed high internal consistency. Convergent validity was supported through negative associations between the ANIQ and borderline personality features and identity diffusion. Incremental validity of the ANIQ over identity diffusion in predicting borderline personality features was also examined, but not supported. Overall, results support the ANIQ as a promising instrument for the assessment of narrative identity in youth. However, some improvements to the ANIQ might be necessary in order to use it as a clinical tool in identifying youth with personality pathology.

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.

Mentalizing in Adolescents with Borderline Personality Disorder

Mentalizing, recognized as the capacity to understand behaviors in the context of our own mental states and those of other people, is being researched more and more commonly in regard to various mental disorders. The research on mentalization focuses on, among other things, borderline personality disorder, which is at present perceived as an emerging problem in the population of adolescents. In order to summarize the currently accessible knowledge of mentalizing in adolescents with borderline personality disorder, we thoroughly analyzed relevant publications. Based on the available literature, it can be concluded that the mentalizing ability of adolescents with borderline personality disorder can be impaired. The evidence demonstrates that they are prone to hypermentalizing, defined as an overattribution of mental states to other people. However, this tendency has not been proven to be specific to teenagers with this disorder. Moreover, the existing data suggest that young people with borderline personality exhibit a reduced capacity to mentalize their own inner states.

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.

Relations between attachment, identity and borderline personality disorder symptom severity in male inpatients with alcohol use disorder

Insecure attachment style and borderline personality disorder (BPD) symptoms are related to the severity of alcohol use disorder (AUD) and can also complicate its course and treatment. We propose a theoretical model of relationships between adult attachment style and BPD and AUD symptom severity in which the sense of identity is a mediator. The aim of our study was to test this model in a sample of male inpatients with AUD. Male inpatients with AUD (N = 114) aged 22-72 years (M = 43.05; SD = 9.84) completed the Experiences in Close Relationships-Revised, the Multidimensional Identity Questionnaire, the Alcohol Use Disorders Identification Test and the Borderline Symptom List 23. Results showed that the sense of identity fully mediated the positive relationship between attachment anxiety and BPD symptom severity. There was also a positive indirect effect of attachment avoidance on BPD symptoms via weaker sense of identity. Contrary to hypothesis, AUD symptom severity was not related to attachment, identity or BPD symptoms in our sample. Sense of identity could be a possible target for interventions for insecurely attached men with AUD to reduce BPD symptoms.

The role of sense of coherence and loneliness in borderline personality disorder traits: a longitudinal twin study

BACKGROUND

Borderline personality disorder (BPD) implies having problems with identity and relations with other people. However, not much is known about whether these indications of BPD are present in adolescence, i.e., before personality disorders usually are diagnosed. In this study, we examined the prediction of an aspect of identity (i.e., sense of coherence [SOC]) and social relations (i.e., perceived loneliness) throughout adolescence on BPD traits in young adulthood. In addition, we examined to what degree the predictive ability could be attributed to genetic and environmental factors. We also examined whether life events in adolescence were related to BPD traits.

METHODS

Three thousand three hundred ninety-one twins, consisting of seven national birth cohorts from Norway, participated in the study. SOC, loneliness and life events were measured three times throughout adolescence with self-report questionnaires, with 2 years in between measurements. BPD traits were measured at the end of adolescence around the age of 19 with a structured interview. Regression analyses were performed to examine the prediction of SOC, loneliness and life events on BPD traits. Cholesky decomposition models were then used to determine to what degree the associations were due to genetic and environmental influences.

RESULTS

The prediction of SOC and loneliness on BPD traits increased from R = .25 (when measured 6 years prior to the assessment of BPD traits) to R = .45 (when measured shortly before the assessment of BPD traits). In addition, negative life events considered dependent on a person's behavior were related to BPD traits. Negative independent and positive dependent life events did not contribute to the prediction of BPD traits. Cholesky decomposition models showed that SOC and loneliness were associated with BPD traits mainly due to shared genetic influences (i.e., the proportion due to genetic influences ranged from 71 to 86%). Adding negative dependent life events to the prediction of BPD traits did not change these percentages.

CONCLUSIONS

These findings indicate that the weaker SOC, the stronger feelings of loneliness, and the negative life events associated with BPD traits are mainly consequences of the genetic aspects of BPD traits, rather than having direct effects on levels of BPD symptoms.

How Does It Feel to Have a Disturbed Identity? The Phenomenology of Identity Diffusion in Patients With Borderline Personality Disorder: A Qualitative Study

Identity diffusion is one of the defining characteristics of borderline personality disorder (BPD). Given its central importance in the formal diagnostic criteria for personality disorders, identity diffusion is remarkably under-researched. In particular, our knowledge of the phenomenology of identity diffusion needs to be improved. This study is based on semistructured interviews with 16 younger women SCID-5-diagnosed with BPD. All interviews were analyzed using the interpretative phenomenological analysis approach. On the basis of this analysis, the patients' descriptions of how identity diffusion manifests itself in their subjective experience are classified into nine categories: disintegrated self-image; using various façades to stabilize the self; painful feelings of the self as broken; feeling that the self does not fit in; inner emptiness; "I don't know what I want"; great need for attention from others to stabilize identity; feeling unable to handle interpersonal relationships; and using sex to distract the self and regulate painful self-states.

Psychometric Properties of a Cultural Adapted Version of the Assessment of Identity Development in Adolescence in Panama

The Assessment of Identity Development in Adolescence (AIDA) is a self-report instrument to detect pathological development of Identity. In Panamá, psychometric instruments for assessment of psychopathology in adolescence are lacking. Our aim was to develop a valid and reliable version of the AIDA Inventory for Panamanian Population. AIDA was adapted to Spanish considering cultural aspects of Panamanian population. Two pilot tests were performed prior to main test to assess item-total correlation at subscale, primary scale and total scale levels and internal consistency at subscale level. A mixed sample of students and PD patients (N = 315) completed the AIDA inventory, the "Strength and Difficulties Questionnaire" and "Defense Style Questionnaire-40." AIDA was retested in a sub sample from school population (n = 98). The Structured Clinical Interview for Axis II Disorders was used for diagnosis of personality disorders in the patient sample (n = 25). Psychometric properties were tested to assess internal consistency, reliability, factorial validity, convergent validity, and criterion validity. AIDA Panama showed excellent internal consistency for the total scale Identity Diffusion with Cronbach's α:0.94 and a retest reliability of 0.84. A Bifactorial CFA was modeled to assess the dimensionality of the inventory. The proportion between OmegaH and Omega at total scales 96% of the variance is explained by a general factor. Furthermore, the Explained Common Variance for the General Factor is 73% supporting unidimensionality. In line with theory, AIDA total scale showed a high positive correlation (r = 0.67) with Total Difficulties scale and high positive correlation (r = 0.71) with Immature Defense scale. The AIDA total score differed highly significant (p = 0.000) between the patient sample and the students with a large effect size (d = 1.02).

CONCLUSION

The adaptation and validation of AIDA for Panamanian adolescent population was successful with good psychometric properties and significant correlations with related psychopathological constructs. AIDA showed high clinical validity by providing a valid discrimination between the school sample and a diagnosed PD sample, in line with the assumption that impaired identity functioning is at the core of personality disorders, especially in adolescence.

Identity Integration in Adolescents With Features of Gender Dysphoria Compared to Adolescents in General Population

Adolescence is an important period for identity formation and identity consolidation is one of the main developmental tasks. Gender identity is an essential aspect of identity but so far little is known about its development. Neither has the identity development of adolescents with features of gender dysphoria (GD) been extensively studied so far. However, adolescents with features of GD have been shown to present extensive psychiatric psychopathology and could therefore be assumed also to have more problems with identity development. We set out to compare the identity integration of adolescents with features of GD (n = 215; 186 natal females, 29 natal males) and adolescents from general population (n = 400; 244 females, 154 males and 2 who did not report their sex) using a culture-adapted Finnish version of an assessment tool for adolescents and young adults on identity in terms of personality functioning, the Assessment of Identity Development in Adolescence (AIDA). AIDA is a 58-item self-report questionnaire enabling dimensional differentiation between healthy and impaired identity development. The continuous AIDA total score (sum score) and its subscales were analyzed using MANOVA, and dichotomized T-scores differentiating identity development in impaired and healthy range using cross-tabulations with chi-square statistics. Adolescents with features of GD showed identity development similar to adolescents in general population. The slight differences seen in AIDA scores were in favor of the GD group. The proportion scoring to identity impairment was lowest among gender-referred adolescents assigned males at birth. Identity integration of the gender-referred adolescents was further compared to that of 77 adolescents in specialist level psychiatric outpatient treatment (67 females, 10 males). The adolescent psychiatric outpatients scored much higher toward impaired identity on all AIDA scales than did the adolescents with features of GD. These results suggest that features of GD are not associated with problems in identity development in adolescents at large. Adolescents with features of GD may have been required to process their identity more, thereby advancing further in their identity consolidation process than young people on average.

Grandiose and vulnerable narcissism, identity integration and self-control related to criminal behavior

BACKGROUND

Although systematic research on narcissism has been conducted for over 100 years, researchers have only recently started to distinguish between grandiose and vulnerable narcissism in relation to criminal behavior. In addition, there is some evidence suggesting that identity integration and self-control may underlie this association. Therefore, the present study aimed to develop a theory-driven hypothetical model that investigates the complex associations between grandiose and vulnerable narcissism, identity integration, self-control, and criminal behavior using structural equation modeling (SEM).

METHODS

The total sample (N = 222) included 65 (29.3%) individuals convicted of criminal behavior and 157 (70.7%) participants from the community, with a mean age of 37.71 years (SD = 13.25). Criminal behavior was a grouping variable used as a categorical outcome, whereas self-report questionnaires were used to assess grandiose and vulnerable narcissism, self-control, and identity integration.

RESULTS

The overall SEM model yielded good fit indices. Grandiose narcissism negatively predicted criminal behavior above and beyond the influence of identity integration and self-control. In contrast, vulnerable narcissism did not have a direct significant effect on criminal behavior, but it was indirectly and positively associated with criminal behavior via identity integration and self-control. Moreover, grandiose narcissism was positively, whereas vulnerable narcissism was negatively associated with identity integration. However, identity integration did not have a direct significant effect on criminal behavior, but it was indirectly and negatively associated with criminal behavior via self-control. Finally, self-control was, in turn, negatively related to criminal behavior.

CONCLUSIONS

We propose that both subtypes of narcissism should be carefully considered in clinical assessment and current intervention practices.

A Dimensional Understanding of Borderline Personality Disorder Using MMPI-2 PSY-5 Scales in Clinical Samples

OBJECTIVE

This study aims to understand borderline personality disorder (BPD) features by employing the Personality Psychopathology Five (PSY-5) scales from the Minnesota Multiphasic Personality Inventory-2 (MMPI-2).

METHODS

A total of 156 psychiatric patients completed PSY-5 scales of MMPI-2 and Personality Assessment Inventory-Borderline Subscale (PAI-BOR). Pearson's partial correlation analysis was conducted to control the impact of age and gender and to determine the relationship between PSY-5 scales and BOR. A hierarchical multiple regression analysis was implemented to examine whether PSY-5 scales predicted the BOR-total, and a path analysis was performed to determine whether PSY-5 scales predicted each PAI-BOR subscale.

RESULTS

The BOR-total score had a significant correlation with all PSY-5 scores, even after controlling for age and gender. However, only aggressiveness (AGGR), disconstraint (DISC), negative emotionality/neuroticism (NEGE), and introversion/low positive emotionality (INTR), excluding psychoticism (PSYC), significantly predicted BOR-total. The path analysis indicates that PSYC did not predict any BOR subscale, while NEGE predicted all BOR subscales.

CONCLUSION

The study findings indicate that NEGE best reflects BPD features, while PSYC is far from the core domain that describes BPD. In addition, the influence of age should be considered when understanding BPD, since age predicted the BOR-total and two BOR subscales.

An Evaluation of Age-Group Latent Mean Differences in Maladaptive Identity in Adolescence

Little is known about the differences between age groups in maladaptive personality function as denoted in Criterion A of the Alternative Model for Personality Disorder (AMPD) in the DSM-5, which is the entry criterion for diagnosing personality disorder in the upcoming ICD-11. The current study aimed to address this gap by evaluating latent mean age group differences in maladaptive identity, which is one aspect that has been identified as an important feature of maladaptive, general personality function as represented in the DSM-5 and ICD-11. We were also interested whether mean differences would track with mean differences in borderline personality disorder (BPD) features given prior data suggesting that general personality function overlap with the construct of BPD. A community sample of N = 2,381 adolescents, representing a mix of different socio-economic and educational backgrounds, ages 12-18 (M = 14.92, SD = 1.94; 46% male) completed a measure of maladaptive identity. A subset (n = 1,165) completed a measure of borderline personality features. Latent variable modeling was used to evaluate latent mean differences across seven age bands. Results suggested a normative increase in maladaptive identity after age 12, which remained consistent until age 17 when it dropped back to levels observed in 12-year-olds. Maladaptive identity was significantly associated with mean-level increases in borderline personality features, with these constructs becoming more closely associated with increasing age.

The Self-Concept and Identity Measure in Adolescents

Abstract. Identity difficulties have been associated with various psychiatric conditions and are considered a central issue in personality pathology. Following the Alternative Model for Personality Disorders, measures of self- and interpersonal functioning have been developed. Although these measures were intended to be separate ratings of self-other deficits, only a global rating was obtained. Moreover, these measures fall short in bridging the gap between developmental and clinical identity work. To capture both adaptive and disturbed identity dimensions, Kaufman et al. (2015) developed the Self-Concept and Identity Measure (SCIM) that assesses consolidated identity, disturbed identity, and lack of identity. Using two-wave longitudinal data (2,150 adolescents; 54.2% girls; age range = 12–19), this study investigated the factor structure and reliability of the Dutch SCIM, its measurement invariance across time, its longitudinal measurement invariance across gender and age groups, and associations of the SCIM with identity synthesis and confusion, Big-Five personality traits, and borderline personality disorder features. Consolidated identity scores were positively related to identity synthesis and adaptive Big-Five traits, whereas negatively related to identity confusion, neuroticism, and borderline features. Opposite associations were obtained for disturbed identity and lack of identity scores. The Dutch SCIM appeared to produce valid and reliable scores and seemed suited to assess longitudinal identity functioning in Belgian adolescents.

Change in the Definition of Personality Disorder in Transition to ICD-11: A Look from Clinical and Developmental Perspectives

The recent body of research reveals fundamental limitations to the categorical concept of a personality disorder that has led researchers to adopt a new personality disorder concept. During the last decade DSM-5 and ICD-11 diagnostic classifications have accepted the dimensional view towards personality pathology. Despite the differences between the two classifications, the joint aspect of both models is the construct of Levels of personality functioning. The construct of personality functioning involves personality (dys)function in the self and interpersonal domains. This two-step conceptualization includes (a) impairments of self and interpersonal functioning, indicating general signs and severity of personality disorder, and (b) pathological personality traits, reflecting ‘stylistic’ differences in the expression of personality disorder. The new conceptualization of personality disorder reflects the innovative multi-theoretical integration of known, empirically-based personality assessment paradigms. The relationship between personality functioning and interpersonal, psychodynamic, and personological paradigms provides the theoretical integrity and empirically-based structure necessary to understand the overall severity of personality pathology. Many methods (interviews, self-assessment scales, and questionnaires) have already been developed for the assessment of personality functioning, and their development will be encouraged by the ICD-11 classification established in 2022. At present, only one instrument has been developed in Lithuania for assessing the level of personality functioning in young people aged 12–18 (Barkauskienė & Skabeikytė, 2020). The empirical data about the validity of this construct and its capability to differentiate between the normal and impaired personality in adults and adolescents provide promising results, but are still accumulating. Research suggests that adolescence is a stage in development when personality pathology can fully unfold and be validly confirmed, which opens up opportunities for early intervention. Although the dimensional personality disorder model needs to further prove its importance, there is already evidence that it is less stigmatizing and returns psychology and personality into the concept of a personality disorder. This review presents changes in the conceptualization of personality disorders by discussing them from both clinical and developmental perspectives and highlighting the results of key research in recent years.

At the Junction of Clinical and Developmental Science: Associations of Borderline Identity Disturbance Symptoms With Identity Formation Processes in Adolescence

Developmental scientists describe the role confusion that can occur for adolescents as they are forming a personal identity. Clinical psychologists describe low self-worth, lack of self-clarity, feelings of emptiness, and dissociation as the key elements of identity disturbance, and they link these to borderline personality disorder. In this study, the authors aimed to work at the juncture of these approaches by considering interrelations between four elements of identity disturbance, typical identity formation processes reflective of identity commitment and confusion, and borderline features. Australian youth (N = 505, 63% female and aged 12-20 years) recruited from clinical and community settings reported on identity commitment, exploration and reconsideration, four elements of identity disturbance, and borderline features. Identity confusion (especially reconsideration) and disturbance were associated with elevated borderline symptoms. Emptiness stood out as the strongest correlate of borderline symptoms. Youth reporting greater emptiness were nearly twice as likely to report a high borderline symptom profile.

The Relations Between Identity Disturbances, Borderline Features, Internalizing Disorders, and Suicidality in Inpatient Adolescents

Previous studies have demonstrated positive associations between identity disturbances and suicidality in adolescents; however, mechanisms underlying these relationships are not well understood. The authors propose that borderline features and various internalizing disorders may mediate these relations. The aim of this study was to test a multiple mediation model of the associations between these constructs using structural equation modeling. Ninety-six inpatient adolescents aged 12-17 years completed the Assessment of Identity Development in Adolescents, the Childhood Interview for DSM-IV Borderline Personality Disorder, the Youth Self-Report, and the Columbia-Suicide Severity Rating Scale. Findings partly confirmed the theoretical model. Borderline features mediated the positive effect of identity disturbances on suicidal ideation severity. Mediations of withdrawn/depression and anxiety/depression on the effect of identity disruption on suicidal ideation intensity were demonstrated. Identity disruptions and borderline and depressive symptoms could be possible targets for interventions for youth experiencing suicidal ideation.

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.

The relationship between prototype ratings of personality and self and interpersonal functioning with an adolescent inpatient sample

Personality pathology is conceptualized, in part, as impairments in self and interpersonal functioning. Although most of the research has focused on adult samples, fewer have looked at this relationship in adolescent samples. This paper investigates the relationship between clinician-rated personality prototypes, the Shedler-Westen Assessment Procedure-Prototype Matching Adolescent Version (SWAP-A-P) derived from the SWAP-II-A, and a measure of self and interpersonal functioning, the Social Cognition and Object Relation Scale-Global Rating (SCORS-G). Clinicians rated 66 adolescents hospitalized at a safety net teaching hospital in the northeast. The patient's individual and group therapist rated the patients at discharge using the SWAP-A-P and the SCORS-G at discharge blind to each other's ratings. Results showed that more severe personality pathology was linked with more impairments in self and interpersonal functioning.

Identity pathology and borderline personality disorder: an empirical overview

Pathological identity-related functioning is a core feature of borderline personality disorder (BPD) that is grievously underrepresented in the empirical literature. Burgeoning evidence indicates that identity pathology is multifaceted, influenced by transactions between social and endogenous processes, and associated with a wide variety of maladaptive outcomes. Although historically defined by patterns of instability (e.g. frequent and rapid changes to career goals, religious beliefs, core values, friend groups, etc.), accumulating research indicates that identity pathology also manifests as distress and functional impairment related to excessive rigidity (i.e. unrelenting negative self-evaluations; overidentification with a restricted role or group membership) and/or incongruous behavior (i.e. simultaneously holding discordant beliefs/values/attitudes, actions that are grossly contradictory with values, incoherent sense of self, etc.). Despite the complex nature of this construct, and its centrality to BPD, researchers often assess identity pathology indirectly, inadequately, or fail to measure it entirely. In this article, we briefly describe how identity pathology may fit into etiological models of BPD, highlight emerging themes from recent research, and identify important gaps in our knowledge. We also discuss limitations associated with current assessment practices, recommend alternatives, and articulate a research agenda for the future.

Diagnosis and Treatment of Borderline Personality Disorder in Young People

PURPOSE OF REVIEW

We review recent research concerning the diagnosis and treatment of borderline personality disorder (BPD) in young people. We examine evidence for the need to define an appropriate age for detection, and the suitability of current classification methods and treatment.

RECENT FINDINGS

Evidence supports early detection and intervention for subsyndromal borderline pathology or categorical BPD across an extended developmental period. A range of structured treatments are effective for BPD in young people, although the role of treatment components in successful outcomes is unclear. Substantial evidence suggests that a stronger focus on functional outcomes, especially social and vocational outcomes, is warranted. Effective treatments for BPD are rarely available internationally. There is a need to assess whether less complex interventions might be developed that are scalable across health systems. A clinical staging model should be considered, addressing clinical distress and co-occurring psychopathology, as well as diagnosis.

Development and Validation of the Interview of Personality Organization Processes in Adolescence (IPOP-A)

The assessment of personality and personality pathology in adolescence represents a critical topic to understand adolescent's difficulties, predict long-term outcome in adulthood, and indicate adequate treatment. Personality Organization, and its underlying dimensions, plays an essential role in shaping how adolescents face their developmental tasks as they are connected with psychosocial functioning and psychopathological severity. However, few measures are available to assess personality organization during adolescence. The aim of the present research is to investigate the psychometric properties of the Interview of Personality Organization Processes in Adolescence (IPOP-A), a semi-structured interview designed for the assessment of the main personality organization dimensions in adolescence. Three studies were performed to explore the psychometric properties of the IPOP-A, in terms of factor structure, reliability, convergent, and discriminant validity. Exploratory and confirmatory factor analysis supported the IPOP-A construct validity. Furthermore, IPOP-A showed good reliability and evidenced a convergent and discriminant validity with DSM-oriented personality patterns, emotion dysregulation, identity disturbance, and psychopathology. Our results provide evidence of IPOP-A validity to assess emerging personality organization in adolescence. Furthermore, the IPOP-A is a promising tool to use in the clinical consultation and treatment planning for the adolescent.

Replication of the Self-Concept and Identity Measure (SCIM) Among a Treatment-Seeking Sample

Identity distress occurs within a variety of psychiatric conditions. Reliable tools for assessing identity-related functioning among clinical populations are greatly needed. The Self- Concept and Identity Measure (SCIM) is a brief self-report scale designed to assess healthy and disturbed identity dimensions. This measure has been validated within normative but not treatment seeking samples. The present study used an a priori confirmatory approach to replicate the SCIM's factor structure among disadvantaged women enrolled in treatment for chemical dependence (N = 216). The original three-factor structure and item loadings generally replicated within this diagnostically diverse, significantly impaired sample. Higher SCIM scores were also associated with other problems, such as emotion dysregulation and depression. Results support the SCIM's use and scoring with clinical populations.

When Does Co-Rumination Facilitate Depression Contagion in Adolescent Friendships? Investigating Intrapersonal and Interpersonal Factors

Research supports the notion that adolescents' mental health is impacted by peers via contagion processes. A growing area of interest has been how co-rumination may influence depressive symptoms within friendships. The current study examined particular conditions under which co-rumination is especially likely to facilitate depression contagion. Participants were adolescents (N = 480, 49% female, M age = 14.6 years, 59.5% European American) paired in friendship dyads and assessed over 9 months. Characteristics of the adolescent (personal distress), of the friend (excessive reassurance seeking), and of the friendship (friendship quality) were considered. Moderated mediation analyses indicated that co-rumination facilitated depression contagion only under conditions of adolescents' high personal distress, friends' high excessive reassurance seeking, and high positive friendship quality. This research underscores the importance of attending to how and under what conditions depression contagion occurs within friendships in order to support adolescents' positive social and emotional development.

Biological and Behavioral Mechanisms of Identity Pathology Development: An Integrative Review

Although identity disturbance is a transdiagnostic mental health problem, modern explanatory models for its emergence are limited. To date, the social, developmental, clinical, and neuropsychological literatures exploring identity processes are also largely disconnected. Existing theories have laid the foundation for understanding important components of identity pathology, yet many overlook biological, behavioral, and interactive processes by which these difficulties may emerge. In this integrative review, we explore how broad transdiagnostic vulnerabilities for psychopathology and more specific risky behavioral processes may reciprocally interact and be refined over time into an identity disturbance profile. Our primary purpose is to review behavioral and biosocial theories and derive a testable conceptual framework for how identity disturbance emerges over the course of development. We aim to describe and integrate several disparate lines of theory and research in order to illuminate potential etiological pathways to identity pathology.

Dimensional measure of self and interpersonal functioning: Comparisons with treatment alliance and readiness for inpatient psychotherapy

The social cognition and object relations scale-global rating method is a clinical rating system assessing 8 domains of self and interpersonal functioning. It can be applied to score numerous forms of narrative data. In this study, we investigate the SCORS-G relationship to measures of alliance and readiness for psychotherapy with an adolescent inpatient sample. Seventy-two psychiatrically hospitalized adolescents were consented and subsequently rated by their individual and group therapist using the SCORS-G. The unit psychiatrist also completed an assessment of patients' readiness for inpatient psychotherapy. The patients completed a self-report of their alliance with the inpatient treatment team as a whole. SCORS-G ratings were positively correlated with assessments of readiness for inpatient psychotherapy and patient-reported alliance. This study further demonstrates the clinical utility of the SCORS-G with adolescents.

Self and identity in borderline personality disorder: Agency and mental time travel

We consider how conceptions of the self and identity from the philosophical literature can help us to understand identity disturbance in borderline personality disorder (BPD). We present 3 philosophical approaches: connectedness, narrative, and agency. We show how these map on to 3 different ways in which the self can be temporally extended. The connectedness approach is dominant in philosophy, and the narrative approach has been used by psychiatry, but we argue that the lesser-known agency approach provides a promising way to theorize some aspects of identity disturbance in BPD. It relates the 2 diagnostic criteria of identity disturbance and disinhibition and is consistent with evidence of memory deficits and altered self-processing in BPD patients.

Childhood Precursors of Adult Borderline Personality Disorder Features: A Longitudinal Study

This study identifies childhood personality traits that are precursors of adult Borderline Personality Disorder (BPD) features. In a longitudinal study, childhood personality traits were assessed at age 11 (N = 100) using the California Child Q-set (CCQ: Block and Block, 1980). A number of these Q-items were found to be significantly correlated (p < 0.001) with a prototype-based measure of BPD features at age 23. Factor analysis of these Q-items suggested that they could be characterized by two underlying personality dimensions: Impulsivity and Nonconformity/Aggression. The findings thus provide evidence that childhood personality traits predict adult BPD features. Identifying such childhood precursors provides an opportunity for early intervention.

L’enfant borderline en devenir II : validation préliminaire de l’Échelle de traits de personnalité limite pour enfants

Le trouble de personnalité limite (TPL) est une psychopathologie sévère qui engendre une grande détresse personnelle et familiale et dont l’étiologie remonte à l’enfance. Les données empiriques appuyant une certaine stabilité temporelle des traits de personnalité de l’enfance à l’adolescence et à l’âge adulte, plusieurs auteurs soutiennent qu’il est possible d’observer chez des enfants et des adolescents des traits de personnalité pouvant être associés aux caractéristiques du TPL à l’âge adulte. Peu d’instruments permettent toutefois d’identifier chez les enfants et les adolescents des traits associés au TPL, d’où l’intérêt du Borderline Personality Features Scale for Children (BPFS-C). Basé sur une perspective développementale, cet instrument mesure les traits de personnalité limite chez les enfants de neuf ans et plus par un questionnaire autorapporté. Une première étude de validation de la version française de l’instrument démontre une cohérence interne très satisfaisante. Les corrélations entre les deux versions de l’instrument (en anglais et en français) sont significatives. L’analyse en composantes principales révèle un modèle en quatre composantes qui présente des similarités avec les quatre sous-échelles de la version anglaise, mais diffère quant à la répartition des énoncés appartenant initialement à la sous-échelle « problèmes d’identité » du BPFS-C. La poursuite de la validation de cet instrument permettrait d’identifier des traits de personnalité et des comportements associés au développement du TPL dans l’enfance et favoriserait la réalisation d’études prospectives afin d’augmenter les connaissances sur l’étiologie du TPL, ses manifestations et sa trajectoire au cours du développement.

Practitioner Review: Borderline personality disorder in adolescence--recent conceptualization, intervention, and implications for clinical practice

BACKGROUND

The past decade has seen an unprecedented increase in research activity on personality disorders (PDs) in adolescents. The increase in research activity, in addition to major nosological systems legitimizing the diagnosis of borderline personality disorder (BPD) in adolescents, highlights the need to communicate new research on adolescent personality problems to practitioners.

SCOPE

In this review, we provide up-to-date information on the phenomenology, prevalence, associated clinical problems, etiology, and intervention for BPD in adolescents. Our aim was to provide a clinically useful practitioner review and to dispel long-held myths about the validity, diagnostic utility, and treatability of PDs in adolescents.

FINDINGS AND CONCLUSION

Alongside providing up-to-date information on the phenomenology, prevalence, and etiology, we also report on associated clinical problems and interventions for adolescent BPD. It is only through early active assessment and identification of youngsters with these problems that a lifetime of personal suffering and health system burden can be reduced or altogether avoided. A variety of evidence-based approaches are now available to treat BPD and related clinical problems in young people. Future research should focus on establishing optimal precision in the diagnostic processes in different treatment settings.

ESCAP Expert Article: borderline personality disorder in adolescence: an expert research review with implications for clinical practice

Borderline personality disorder (BPD) has onset in adolescence, but is typically first diagnosed in young adulthood. This paper provides a narrative review of the current evidence on diagnosis, comorbidity, phenomenology and treatment of BPD in adolescence. Instruments available for diagnosis are reviewed and their strengths and limitations discussed. Having confirmed the robustness of the diagnosis and the potential for its reliable clinical assessment, we then explore current understandings of the mechanisms of the disorder and focus on neurobiological underpinnings and research on psychological mechanisms. Findings are accumulating to suggest that adolescent BPD has an underpinning biology that is similar in some ways to adult BPD but differs in some critical features. Evidence for interventions focuses on psychological therapies. Several encouraging research studies suggest that early effective treatment is possible. Treatment development has just begun, and while adolescent-specific interventions are still in the process of evolution, most existing therapies represent adaptations of adult models to this developmental phase. There is also a significant opportunity for prevention, albeit there are few data to date to support such initiatives. This review emphasizes that there can be no justification for failing to make an early diagnosis of this enduring and pervasive problem.

Borderline personality disorder in transition age youth with bipolar disorder

OBJECTIVE

To determine the longitudinal impact of borderline personality disorder (BPD) on the course and outcome of bipolar disorder (BP) in a pediatric BP sample.

METHOD

Participants (N = 271) and parents from the Course and Outcome of Bipolar Youth (COBY) study were administered structured clinical interviews and self-reports on average every 8.7 months over a mean of 93 months starting at age 13.0 ± 3.1 years. The structured interview for DSM-IV personality disorders (SIDP-IV) was administered at the first follow-up after age 18 to assess for symptoms of BPD. BPD operationalized at the disorder, factor, and symptom level, was examined as a predictor of poor clinical course of BP using all years of follow-up data.

RESULTS

The number of BPD symptoms was significantly associated with poor clinical course of BP, above and beyond BP characteristics. Affective dysregulation was most strongly associated with poor course at the factor level; the individual symptoms most strongly associated with poor course were dissociation/stress-related paranoid ideation, impulsivity, and affective instability.

CONCLUSION

BPD severity adds significantly to the burden of BP illness and is significantly associated with a more chronic and severe course and outcome beyond what can be attributable to BP characteristics.

Dimensional assessment of self- and interpersonal functioning in adolescents: implications for DSM-5's general definition of personality disorder

Central to the proposed DSM-5 general definition of personality disorder (PD) are features of self- and interpersonal functioning. The Social Cognition and Object Relations Scale-Global Rating Method (SCORS-G) is a coding system that assesses eight dimensions of self- and relational experience that can be applied to narrative data or used by clinically experienced observers to quantify observations of patients in ongoing psychotherapy. This study aims to evaluate the relationship of SCORS-G dimensions to personality pathology in adolescents and their incremental validity for predicting multiple domains of adaptive functioning. A total of 294 randomly sampled doctoral-level clinical psychologists and psychiatrists described an adolescent patient in their care based on all available data. Individual SCORS-G variables demonstrated medium-to-large effect size differences for PD versus non-PD identified adolescents (d = .49-1.05). A summary SCORS-Composite rating was significantly related to composite measurements of global adaptive functioning (r = .66), school functioning (r = .47), externalizing behavior (r = -.49), and prior psychiatric history (r = -.31). The SCORS-Composite significantly predicted variance in domains of adaptive functioning above and beyond age and DSM-IV PD diagnosis (ΔR(2)s = .07-.32). As applied to adolescents, the SCORS-G offers a framework for a clinically meaningful and empirically sound dimensional assessment of self- and other representations and interpersonal functioning capacities. Our findings support the inclusion of self- and interpersonal capacities in the DSM-5 general definition of personality disorder as an improvement to existing PD diagnosis for capturing varied domains of adaptive functioning and psychopathology.
