Empirical typology of adolescent personality organization

Dimensional model of adolescent personality pathology, reflective functioning, and emotional maltreatment

Introduction

Childhood emotional abuse (CEA) is a recognized risk factor for adolescent mentalizing challenges. However, there's limited understanding about how CEA might influence personality development and elevate the risk of adolescent personality pathology. A deeper grasp of these pathways is crucial, given that adolescence is a pivotal developmental phase for identity integration, personality consolidation, and the emergence of personality disorders. As the emphasis shifts to dimensional perspectives on adolescent personality pathology, the spotlight is increasingly on adolescents' evolving personality organization (PO). Within this framework, personality disorder manifestations stem from inherent vulnerabilities in PO. A comprehensive understanding of how CEA leads to these inherent vulnerabilities in PO can inform enhanced interventions for at-risk adolescents. Nonetheless, our comprehension lacks insight into potential pathways to PO, especially those involving external factors like maltreatment and individual traits like mentalizing. This study sought to bridge these gaps by employing latent factor analysis and structural equation modeling to explore connections between emotional maltreatment, adolescent mentalizing, and PO.

Methods

A community-based cohort of 193 adolescents (aged 12-17) took part in self-report assessments: the Childhood Experience of Care and Abuse Questionnaire (CECA.Q), the Reflective Functioning Questionnaire for Youth (RFQ-Y), and the Inventory for Personality Organization for Adolescents (IPO-A).

Results

The structural equation model revealed a significant direct influence of CEA on both RFQ-Confusion and PO, and a noteworthy direct effect of RFQ-Confusion on PO. Remarkably, the model accounted for 76.9% of the PO variance. CEA exhibited a significant indirect impact on PO through RFQ-Confusion, which was accountable for 52.3% of the CEA effect on PO, signifying a partial mediation by mentalizing.

Discussion

These insights carry substantial clinical implications, especially for devising integrated, trauma-informed strategies for adolescents with personality pathologies. This is particularly relevant for enhancing mentalizing and bolstering personality consolidation among adolescent CEA survivors.

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.

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.

Transference-Focused Psychotherapy for Adolescents With Personality Disorders

This article presents a conceptualization of personality disorders in adolescence and the adaptation of transference-focused psychotherapy (TFP) for personality disordered adolescents (TFP-A). The model of assessment and treatment presented is based on contemporary psychoanalytic object relations theory developed by Otto F. Kernberg and supported by findings from current evidence-based outcome research. We present a method of assessing personality disorders in adolescents that addresses the variability of personality disorder symptoms and traits among adolescents and their instability over time. We then present the goal of TFP-A and its major phases of implementation. A major focus is therapist interventions.

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.
