Maladaptive personality traits in depressive and substance use disorders: A study with the PID-5.

Studies on the relationship between personality and depressive disorders (DD) or substance use disorders (SUD) often refer to the normal personality model and focus mainly on the "big" factors. Domain level results with the Personality Inventory for DSM-5 (PID-5) tend to be consistent with NEO-PI-R or NEO-FFI results, however facet level results in the specific characteristics of these disorders are scarce. The main objective of this study was to characterize DD and SUD's maladaptive personality traits through the PID-5. A sample of DD was compared with a sample of SUD, with a sample of other disorders, and with a community sample. A sample of the general Portuguese population (N = 693) and a heterogeneous clinical sample (N = 310) were studied. Participants responded to the PID-5 and to the Brief Symptom Inventory (BSI). Depressivity, Irresponsibility and Anhedonia were the main characteristics of DD. However, high values in Depressivity and in depressive symptomatology were present in all the clinical subsamples. Irresponsibility, Deceitfulness and Callousness were the main characteristics of SUD. The occurrence of DD, SUD or Other disorders could be predicted using multinonomial logisitic regression analysis, and PID-5 facets as independent variables. These results are in line with comorbidity data and tend to confirm the PID-5 validity.

Cross-cultural Study of the Personality Inventory for the DSM-5 (PID-5) across the Portuguese and the United Arab Emirates (UAE) Community and Clinical Populations.

Aims: The present paper focused on compare the PID-5 mean score levels across two matched community and clinical samples of Portugal and the UAE. Background: The generalizability and universality of the Alternative Model of Personality Disorders has been thoroughly studied through the Personality Inventory for DSM-5 (PID-5) across countries and languages. However, studies comparing Western and Middle Eastern countries are still limited, in particular those who assess the PID-5 measurement invariance. Objectives: We examined measurement invariance of the PID-5 scales across matched Emirati and Portuguese clinical and nonclinical groups, as well as compare and contrast the PID-5 mean score levels across both countries and samples. Methods: The Arabic and the Portuguese versions of the PID-5 was administered to Emirati community participants (N = 300, 80% women and 20% men, Mage = 27.95) which were matched with Portuguese community participants (N = 300, 80.3% women and 19.7% men, Mage = 28.96), as well as clinical participants of the UAE (N = 150, 61.3% women and 38.7% men, Mage = 31.29) and Portugal (N = 150, 52% men and 48% women, Mage = 44.97). We examined measurement invariance through an unrestricted Factor Analysis based program, and mean scores levels were compared and analyzed. Results: Our findings supported the PID-5 measurement invariance across the Emirati and Portuguese clinical samples pointing to the universality and generalizability of the Alternative Model of Personality Disorders. The Emirati psychiatric sample exhibited somehow higher results than the Portuguese psychiatric participants, albeit the small effect size for most of the PID-5 scales. Conclusion: Further research is needed to examine the applicability of the PID-5 across non-clinical representative samples of Portugal and the UAE, and other Middle Eastern countries.

The predictive power of personality through psychopathology in Alzheimer's disease: a control study of self-report and baseline retrospective assessment.

Although there is a growing body of literature on the Alzheimer's disease (AD) personality changes, its relationships with personality disorders are still largely understudied. The relationships between the Five-Factor Model and the Axis II personality disorders were explored in the context of current and baseline personality in AD. The study was conducted with four groups who were administered the NEO-FFI and the PDQ-4+, mainly in interview sessions. Self-report measurement: AD Group, 40 female participants (M = 81.48 years); Control Group, 47 female participants from the population at large (M = 76.81 years). Baseline retrospective measurement: AD Group Informants (n = 40); Control Group Informants (n = 47). Three logistic regressions were computed. The baseline Neuroticism moderates the Neuroticism in the current clinical state. High Neuroticism, low Openness, high Cluster B, and baseline high Neuroticism, predicted the presence of AD diagnosis, accounting for 85% of the variance. In order to increase sensitivity towards an earlier diagnosis in AD, future empirically-based research should take into account an assessment set of structural personality variables.

Personality traits and personality disorders in older women: an explorative study between normal development and psychopathology.

The relationships between Axis II personality disorders (DSM-IV) and the Five-Factor Model (FFM) were explored in older women. The sample consists of 90 participants (M = 72.29 years, SD = 7.10) who were administered the NEO-Five-Factor Inventory and the Personality Diagnostic Questionnaire. The highest prevalence of A and C clusters and obsessive-compulsive personality disorder was observed. Also, elevated neuroticism and decreased agreeableness and openness appear as valuable traits in the description of psychopathology. The study of maladaptive personality functioning within an aging population can be described with the same traits that underlie normal personality functioning, extending the range of psychopathology to a dimensional approach.

Homeless people: a review of personality disorders.

Personality disorders in homeless people pose a challenge to the medical community and society, requiring specialized approaches for these super-difficult patients. The prevalence of personality disorders is higher in homeless populations than in the general population. However, there is a knowledge gap regarding personality disorders among people experiencing homelessness, and the implications of this lack of recognition are substantial. This paper provides a brief narrative review of personality disorders among homeless individuals. The primary importance and specificity of these disorders in this population remain unexplored. We searched PubMed and Web of Science databases in February and November 2023 using the keywords 'homeless' and 'personality disorder', and selected fifty-eight studies to be included in this literature review. The main themes of the results were personality disorders in homeless individuals and comorbid psychiatric disorders; risk factors and other psychological and behavioral data; clinical and intervention outcomes; and challenges linked to assessment, treatment, and intervention. The homeless population experiences significant diagnostic variability and the diagnosis of personality disorders is still evolving, contributing to difficulties in diagnosis, assessment, and treatment. A future challenge is to raise clinical awareness and optimize research knowledge, assessment, and intervention in personality disorders among homeless individuals with comorbid psychiatric disorders.

The Portuguese version of the self-report form of the DSM-5 Level of Personality Functioning Scale (LPFS-SR) in a community and clinical sample.

The Level of Personality Functioning Scale-Self-Report (LPFS-SR) operationalizes Criterion A of the DSM-5 Alternative Model for Personality Disorders. The current study aimed 1) to examine the internal consistency of the Portuguese version of the LPFS-SR in a community sample and a clinical sample, 2) to compare non-clinical participants (N = 282, Mage = 48.01, SD = 10.87) with two samples of clinical participants, one composed of patients with a personality disorder diagnosis (PD sample, n = 40, Mage = 46.18, SD = 13.59) and the other of patients with other psychiatric diagnoses (OD sample, n = 148, Mage = 49.49, SD = 11.88), with respect to LPFS-SR dimensions and total score, 3) to examine the capacity of the LPFS-SR to discriminate between samples through the ROC curve analyses, and 4) to examine the factor structure of the Portuguese version of the LPFS-SR. The Portuguese version of the LPFS-SR revealed adequate internal consistency results, akin to the original data, in the community and clinical samples. The community sample differed significantly from both clinical samples in all the LPFS-SR dimensions and total score. The ROC curve analysis indicated an optimal cut-off for the total score of 272.00, corresponding to a sensitivity of 75% and a specificity of 89%, in the PD vs. community samples. The LPFS-SR total score discriminative capacity between the PD and OD samples was lower, albeit also significant (area-under-the-curve of .63; p = .027; 95% CI: .52-.74). The current study provided evidence of the LPFS-SR's unidimensionality in both community and clinical samples. Although this study has limitations, its findings contribute to a deeper understanding of the LPFS-SR construct, as well as to its cross-cultural validation.

Personality traits and disorders in Alzheimer's disease.

BACKGROUND: The relationships between axis II personality disorders and the normative personality traits were explored in the context of current and pre-morbid personality assessment in Alzheimer's disease (AD). METHODS: The study was conducted with four groups who were administered the NEO-FFI and the PDQ-4+, in the form of individual interview sessions. Current personality measure: consisting of 44 female participants (AD group) and, the control group, consisting of 80 female participants from the population at large. Pre-morbid personality measure: AD group informants (n = 40); control group informants (n = 42). RESULTS: The results are in line with the literature review and provide new research data. By factorial discriminant analysis, the current and pre-morbid personality variables that differentiate AD from control groups are identified. The personality traits variables are the best discriminators such as low agreeableness, low openness to experience, and high neuroticism, suggesting that the maladaptive personality functioning can be described extending the range of psychopathology to a dimensional approach. CONCLUSIONS: The study of personality variables seems to suggest, in their inclusion, the possibility to increase sensitivity toward an assessment in AD.

Psychotic spectrum features in borderline and bipolar disorders within the scope of the DSM-5 section III personality traits: a case control study.

BACKGROUND: Psychotic spectrum features in borderline personality disorder (PD) are a long-standing phenomenon, but remarkably, to date, they have not been the focus of many empirical studies. Moreover, the comparative studies that acknowledge their links to affective psychoses are even more scarce. Likewise, the contributions of empirical research on the DSM-5 dimensional approach to this topic are also uncommon. This study seeks to identify the best set of pathological personality traits and/or symptoms that are predictors of psychotic features (psychoticism and ideation paranoid symptoms) in borderline PD and in bipolar disorder, based on the framework of the DSM-5 section III personality traits. METHODS: A cross-sectional study of two clinical samples: 1) Borderline PD group of 63 participants; 2) Bipolar disorder group of 65 participants. Self-reported assessment: Personality Inventory for DSM-5 (PID-5); Brief Symptom Inventory (BSI). A series of linear and logistic regression analyses were computed. RESULTS: Overall, the data emerging as common predictors are detachment, negative affectivity, psychoticism, depressivity, grandiosity, suspiciousness and interpersonal sensitivity symptoms. Borderline PD has the highest score in BSI paranoid ideation which emerges as its discriminating trait (Nagelkerke R2 = .58): cognitive and perceptual dysregulation (OR: 13.02), restricted affectivity (OR: 12.09), withdrawal (OR: 11.70), anhedonia (OR: 10.98) and emotional lability (OR: 6.69). CONCLUSIONS: Besides the commonality that appears to overlap both disorders with a psychosis superspectrum, the patterns of the pathological personality-symptoms underlying the psychotic features appear to reinforce a position between schizophrenia and bipolar disorders that borderline PD may occupy, highlighting the possibility of its intersection with schizoaffective/psychosis spectra. The pathological personality nature of the psychotic features emerges as a potential comprehensive trait of the phenomenological dimensions.

Bridging the ICD11 and the DSM-5 personality disorders classification systems: The role of the PID5BF + M.

Introduction: In both the ICD-11 Classification of Personality Disorders and the DSM-5 Alternative Model of Personality Disorders (AMPD) personality disorders (PD) are characterized by impairments in self- and interpersonal functioning which distinguish the various levels of dysfunction. Moreover, pathological traits are used by these classification systems to define the stylistic expression of personality dysfunction. Negative affectivity, detachment, antagonism/dissociality, and disinhibition feature as trait domains in each of these models. However, there are also differences between the two models, namely, in the psychoticism domain, which does not feature as a personality trait domain in the ICD-11, and in the anankastia domain, corresponding to compulsivity in the DSM-5, which was removed from the final AMPD model. Furthermore, facets are acknowledged by the DSM-5 within each trait domain, while this does not occur in the ICD-11. In view of the similarity between these classification systems, their harmonization would be beneficial for the clinical profession. With this goal in mind, the PID5BF + M, an algorithm that assesses the DSM-5 and ICD-11 six trait domains and 18 facets, was developed and has proven to adequately characterize the ICD-11 trait domains by means of DSM-5 trait facets. Methods: The current study compares a community sample (N = 280, M age = 48.01, 53.2% females) with a PD sample (N = 131, M age = 42.66, 45.0% females) along with the PID5BF + M, the LPFS-SR and the PID-5. Given that the PID5BF + M total can be seen as a measure of the level of personality dysfunction, strong relations between the PID5BF + M total and the LPFS-SR total are expected. Strong relations between the trait specifiers measured by the PID5BF + M and the PID-5 are also expected. Finally, the community and clinical samples are expected to differentiate by means of the dimensions assessed through the three afore-mentioned measures. The Spearman rank-order correlation coefficient was used to measure the strength and direction of associations between the PID5BF + M total and the LPFS-SR total and between the PID5BF + M and the PID-5 traits. Group differences were explored using the Mann-Whitney U test for independent samples. Results: As expected, there were strong, significant, and positive relations between the measures. Furthermore, higher scores were observed in all the variables for the PD group against the community group. Discussion: Although this study has limitations, its findings sustain that the PID5BF + M has potential to assess the severity of personality disfunction and to characterize the stylistic features of PD as they are conceived by both the ICD-11 and the DSM-5. Although more research is needed regarding the convergent validity of the PID5BF + M, this new test contributes to the harmonization of both systems and to parsimony in the assessment of PD, which is the main objective of clinical practice.

Psychopathology Changes in Alzheimer's Disease.

The advances in knowledge about the association between personality and neuropathology in Alzheimer's disease have been highlighted. This research is oriented to the evaluation of personality changes in the screening of axis II personality disorders in Alzheimer's disease. The investigation was managed with four groups to whom were applied the PDQ-4+ in individual interviews. Some results are in line with the state-of-the-art review and we also provide new research data. A higher global personality disorder index and greater incidence of clusters C (anxious) and A (odd/eccentric) are confirmed as personality changes. Interpretive possibilities of the data and their implications for the study of psychopathology changes in Alzheimer's disease are discussed.

The Self-Administered Version of the Structured Interview for Disorders of Extreme Stress (SIDES-SR) in a Clinical and Non-Clinical Portuguese Sample.

Disorders of Extreme Stress Not Otherwise Specified (DESNOS) refers to a constellation of symptoms deriving from chronic interpersonal trauma, inflicted by caregivers or in the context of intimate relationships. The Structured Interview for Disorders of Extreme Stress-Self-Report (SIDES-SR) was designed for the assessment of DESNOS. This study aimed to validate the Portuguese version of the SIDES-SR in the community (N = 814; Mage = 40.09, SD = 14.25, 39.2% male, 60.8% female) and clinical (N = 310; Mage = 42.49, SD = 12.47, 57.7% male, 42.3% female) samples. It had three objectives: (1) to validate the SIDES-SR rationally derived domains in the community sample; (2) to characterise the reliability of the SIDES-SR scales in both samples; and (3) to explore mean differences in the SIDES-SR results in both samples. The Portuguese SIDES-SR confirmed the six clinical domains of DESNOS and demonstrated acceptable internal consistency levels, similar to those obtained in prior research. Highly significant differences and large and very large effect sizes between the community and clinical samples were found for all the SIDES-SR domains. DESNOS symptomatology was shown to be more frequent in females and the clinical sample reported a higher frequency of traumatic events in life, specifically interpersonal trauma. The results support the relevance of the SIDES-SR for clinical practice in the assessment of the DESNOS diagnosis.

In light of the DSM-5 dimensional model of personality: Borderline personality disorder at the crossroads with the bipolar spectrum.

BACKGROUND: State-of-the-art research highlights that borderline personality disorder (PD) and bipolar spectrum disorders have clinical characteristics in common, which imply uncertainty in differential diagnoses. Although there is a growing body of literature on the DSM-5 dimensional model of personality disorder, its discriminative features between these clinical samples are still understudied. In this study, we seek to identify the best set of predictors that differentiate between borderline PD and bipolar spectrum, based on pathological and normative personality traits and symptoms. METHODS: A cross-sectional study of three clinical samples: 1) Borderline PD group of 63 participants; 2) Major depressive disorder group of 89 participants; 3) Bipolar disorder group of 65 participants. Self-reported assessment: Personality Inventory for DSM-5; Brief Symptom Inventory; FFM Inventory. A series of one-way ANOVAs and logistic regression analyses were computed. RESULTS: The major set of data emerging as common discriminants of borderline PD across the bipolar spectrum are unusual beliefs & experiences, paranoid ideation, obsession-compulsion and extraversion. Depressivity (OR: 34.95) and impulsivity (OR: 22.35) pathological traits displayed the greatest predictive values in the differential diagnosis. LIMITATIONS: The small size of the samples; a lack of data from participants' previous clinical history. CONCLUSIONS: Findings support the DSM-5 pathological traits as differentiating borderline PD through bipolar spectrum, and reinforcing the joint use of symptom-related pathological functioning and normal-range personality traits. Alongside the bipolar spectrum, borderline pathology sheds light upon a hypothetical overlap along the depressive and schizoaffective/schizophrenia spectra, representing a borderland space at a crossroads with the psychopathology of a meta-spectrum.

The Utility of ICD-11 and DSM-5 Traits for Differentiating Patients With Personality Disorders From Other Clinical Groups.

The ICD-11 Classification of Personality Disorders delineates five trait domain qualifiers (i.e., negative affectivity, detachment, dissociality, disinhibition, and anankastia), whereas the DSM-5 Alternative Model of Personality Disorders also delineates a separate domain of psychoticism. These six combined traits not only characterize individual stylistic features, but also the severity of their maladaptive expressions. It was, therefore, the aim of this study to investigate the utility of ICD-11 and DSM-5 trait domains to differentiate patients with personality disorders (PD) from patients with other mental disorders (non-PD). The Personality Inventory for DSM-5 Brief Form Plus (PID5BF+M) was administered to a sample of patients diagnosed with a personality disorder (N = 124, M age = 42.21, 42.7% females) along with a sample of patients diagnosed with other mental disorders (N = 335, M age = 44.83, 46.6% females). Group differences were explored using the independent sample t test or the Mann-Whitney U test for independent samples, and discriminant factor analysis was used to maximize group differences for each trait domain and facet score. The PD group showed significantly higher scores for the total PID5BF+M composite score, for the trait domains of negative affectivity, antagonism/dissociality, and disinhibition and for the trait facets of emotional lability, manipulativeness, deceitfulness, and impulsivity. The trait domains of disinhibition, negative affectivity, and antagonism/dissociality as well as the trait facets of impulsivity, deceitfulness, emotional lability, and manipulativeness were the best discriminators between PD and non-PD patients. The global PID5BF+M composite score was also one of the best discriminators supporting its potential as a global severity index for detecting personality dysfunction. Finally, high scores in three or more of the 18 PID5BF+M facets suggested the possible presence of a PD diagnosis. Despite some limitations, our findings suggest that the ICD-11 and DSM-5 traits have the potential to specifically describe the stylistic features that characterize individuals with PD, including the severity of their maladaptive expressions.

Personality disorders characterized by anxiety predict Alzheimer's disease in women: A case-control studies.

This research is geared toward the evaluation of current and pre-morbid personality psychopathology in Alzheimer's disease (AD). The study was conducted with four groups who were administered the Personality Diagnostic Questionnaire-4+, mainly in the form of individual interviews. Current measurement: AD Group, 44 female participants (M = 81.36 years); Control Group, 80 female participants from the population at large (M = 75.84 years). Pre-morbid measurement: AD Group Informants (n = 40); Control Group Informants (n = 42). The incidence of all clusters in clinical state are significant, and Cluster B incidence in pre-morbidity is evidenced. Cluster C is highlighted throughout the life course as a predictor. Logistic regression analyses showed that schizotypical, narcissistic, avoidant, obsessive-compulsive, pre-morbid schizotypical, pre-morbid histrionic, and pre-morbid obsessive-compulsive personality disorders, predicted the presence of AD diagnosis, accounting for 49% of the variance. These findings are relevant to research relating personality and psychopathology in Alzheimer's disease.

The Portuguese version of the Personality Inventory for the DSM-5 in a community and a clinical sample.

The Personality Inventory for DSM-5 (PID-5) measures the maladaptive traits of the model for personality and its disorders, as proposed in section III of the DSM-5. The current study aimed to examine whether the Portuguese PID-5 distinguished non-clinical participants (N = 1223, Mage  = 36.73, standard deviation = 15.72) from clinical participants (N = 202, Mage  = 43.82, standard deviation = 11.33) with respect to dysfunctional personality traits and to explore the PID-5 factor structure in both samples. The PID-5 scale medians were higher in the clinical sample than in the community sample. All analyses were statistically significant (p ≤ 0.001) with medium size effects. In the community sample, a five-factor structure emerged, and the factors resembled the PID-5 domains. However, in the clinical sample, a four-factor structure was retained, in which the Psychoticism domain did not clearly emerge. The composition of the clinical sample along with its small size may account for these unexpected results. Overall, the results provide evidence of the PID-5's ability to distinguish between psychiatric and community individuals and of the model's structural similarity in community samples, across studies and nationalities. More research is required to understand the Portuguese PID-5 structure in clinical samples. © 2018 John Wiley & Sons, Ltd.

Depressive vulnerability in women with Alzheimer's disease: Relationship with personality traits and abnormal personality dimensions.

BACKGROUND: This study sought to determine the evaluation of current and pre-morbid depressive vulnerability dimensions in Alzheimer's disease. Sidney Blatt´s personality developmental perspective, the Five-Factor model and Axis II personality disorders were taken as references. METHODS: The study was conducted with two groups which were assessed using the Depressive Experiences Questionnaire, the NEO-FFI and the Personality Diagnostic Questionnaire-4+, in the form of individual interview sessions. Current personality measure: Alzheimer's disease Group, consisting of 44 female participants (MAge = 81.36 years); Pre-morbid personality measure: Alzheimer's disease Group Informants (n = 40). RESULTS: Self-Criticism personality vulnerability is a general indicator of psychopathology. In pre-morbidity, Neuroticism (ß = 0.41), Agreeableness (ß = -0.63) and Conscientiousness (ß = -0.08) predicted Self-Criticism, explaining 64% of the variance; additionally, Self-Criticism (ß = 0.72) and Neediness (ß = 2.05) predicted the PDQ-4+ total, explaining 58% of the variance. In terms of current personality, the PDQ-4+ total was predicted by Self-Criticism (ß = 0.55), explaining 30% of the variance. LIMITATIONS: The small size of the samples, especially since it is difficult to access individuals diagnosed with AD at the onset or in its early stages; measuring personality changes by means of retrospective assessment by proxies may have introduced some memory bias. CONCLUSIONS: These findings are relevant to research relating depressive vulnerability to personality traits and psychopathology in Alzheimer's disease.

Evaluation of the PID-5 depressivity personality dimensionsand depressive symptomatologyin a community sample / Evaluación de las dimensiones de la personalidad depresiva en el PID-5 y de la sintomatología depresiva en una muestra comunitaria

The alternative model for the classification of personality disor-ders presented in the DSM-5 is based on the hypothesis of continuity be-tween normal personality and personality disorders. The main objective of this study is to analyze the relationship between depressive symptomatolo-gy and the domains and facets of the PID-5, especially the Depressivity facet. A convenience sample of the general population (N = 453) was used. Participants responded to the PID-5 and the CES-D. In a multiple regression model including all the PID-5 facets, only Depressivity and An-hedonia had a significant individual effect on predicting the CES-D score. Correlation analysis suggested that Depressivity and Anhedonia could be considered as defining the depressive traits of personality disorders and supported the continuity between these disorders and depressive sympto-matology. A Taxometric Analysis with the Depressivity facet and CES-D score as indicators supported the dimensional nature of depressivity in a broad sense (depressive traits/ depressive symptomatology).(AU)

El modelo alternativo para la clasificación de los trastornos de la personalidadpresentado en el DSM-5 se basa en la hipótesis de conti-nuidad entre la personalidad normal y los trastornos de la personalidad. El objetivo principal de este estudio es analizar la relación entre la sintomato-logía depresiva y los dominios y facetas del PID-5, especialmente la faceta Depresión. Se utilizó una muestra de conveniencia de la población general (N = 453). Los participantes respondieron al PID-5 y a la CES-D. En un modelo de regresión múltiple que incluía todas las facetas de PID-5, solo la Depresión y la Anhedonia tuvieron un efecto individual significativo en la predicción de la puntuación CES-D. El análisis de correlación sugirió que la Depresión y la Anhedonia podrían considerarse como la definición de los rasgos depresivos de los trastornos de la personalidad y apoyó la conti-nuidad entre estos trastornos y la sintomatología depresiva. Un análisis ta-xométrico con la faceta Depresión y la puntuación CES-D como indicado-res respaldó la naturaleza dimensional de la depresión en un sentido amplio (rasgos depresivos / sintomatología depresiva).(AU)

Five-factor model personality domains in the prediction of Axis II personality disorders: an exploratory study in late adulthood women non-clinical sample.

Relationships between Axis II personality disorders (DSM-IV) and the five-factor model were explored in a non-clinical sample of late adulthood women. The sample consists of 90 women (M = 72.29 years of age, standard deviation = 7.10), who were administered with two measures, the NEO-FFI and the Personality Diagnostic Questionnaire-4+. Some personality disorders scales such as paranoid, schizotypal, borderline and dependent demonstrate a differentiated pattern of five-factor model domain predictors. Low agreeableness predicted schizoid, narcissistic and antisocial; histrionic, obsessive-compulsive and negativistic were predicted by high neuroticism and low agreeableness; high neuroticism and low extraversion, in turn, predicted dependent and depressive scales. Also, two clusters of personality disorders are identified, one associated with low agreeableness and another with low agreeableness and high neuroticism. This study suggest that some traits become maladaptive personality traits, and correspond more closely to psychopathology, when they become opposite to what would be expected in line with studies in normal late adulthood development.

Personality disorders as an expression of the dimensional polarity in personality development in late adulthood women.

Relationships between Axis II personality disorders and Sidney Blatt constructs of dependency and self-criticism were explored in a late adulthood women sample. The sample consisted of 102 women (M = 72.07 years of age, SD = 7.04) who were administered two measures, the Personality Diagnostic Questionnaire-4+ and the Depressive Experiences Questionnaire. The histrionic, dependent, and obsessive-compulsive personality disorder scales are shown to be significant predictors of dependency, and the narcissistic, borderline, and avoidant scales are significant predictors of self-criticism. The application of a dimensional interpersonal approach to psychopathology is discussed.

Predicting relatedness and self-definition depressive experiences in aging women based on personality traits: a preliminary study.

As part of the research relating personality and depression, this study seeks to predict depressive experiences in aging women according to Sidney Blatt's perspective based on the Five-Factor Model of Personality. The NEO-Five Factor Inventory and the Depressive Experiences Questionnaire were administered. The domains Neuroticism, Agreeableness, and Conscientiousness predicted self-criticism, explaining 68% of the variance; the domains Neuroticism and Extraversion predicted dependency, explaining 62% of the variance. The subfactors Neediness and Connectedness were differently related to personality traits. These findings are relevant to the research relating personality and anaclitic / introjective depressive experiences in late adulthood.
