The discriminant validity of paranoid personality disorder has been recently questioned, and paranoid presentations are now conceived of as transdiagnostic features of personality disorders (PDs). However, empirical results are inconsistent. This study investigated the link between subclinical personality disorders (except paranoid PD) and paranoid...

The COVID-19 pandemic was not only a biological challenge, but it also took a toll on the psychological and social well-being of older adults, especially those in nursing homes. This study aims to uncover the impact of the pandemic on the biopsychosocial well-being of nursing home residents, including the role of COVID-19 positivity and social cont...

Shame may be a transdiagnostic marker of psychopathology and might potentially have a negative impact on treatment outcome. This scoping review maps the empirical literature on shame and psychotherapy, with a focus on individual therapy. Searching the terms shame and psychotherapy in PubMed and PsycInfo, we identified 2,520 unique records. After sc...

Although interindividual differences in narcissism are well studied, little is known about assessing narcissism at the within-person level. To fill this research gap, we investigated whether the narcissism construct is represented in the same way at the between- and within-person levels. We analyzed four established narcissism measures across multi...

The COVID-19 pandemic has negatively impacted adults’ mental health around the world. Various studies highlighted the role of sociodemographic risk factors, including age, gender, and level of education, in increasing this impact. Although insecure attachment styles are considered a vulnerability factor for psychopathology and difficulties in copin...

While the objective level of intelligence is not associated with narcissism, relations to self-assessed intelligence (SAI) have been repeatedly reported. Existing research suggests that different facets of narcissism may have different associations with SAI. In the current daily diary study ( N = 176; N = 3975 total observations), we employed dynam...

Adolescence is a period of rapid physical, psychological, and neural maturation that makes youth vulnerable to emerging psy-chopathology, highlighting the need for improved identification of psychopathology risk indicators. Recently, a higher-order latent psychopathology factor (p-factor) was identified that explains latent liability for psychopath...

Introduction: Both variable- and person-centered approaches identify grandiose and vulnerable themes in pathological narcissism (PN). However, person-centered results rely on cross-sectional data, preventing identification of subtypes of individuals through transitory self-states. Methods: We perform a cluster analysis on the joint trajectory of da...

Recent diagnostic developments suggest that paranoia is a transdiagnostic characteristic common to several personality disorders rather than a personality disorder per se. Nonetheless, empirical literature fails to provide comprehensive and univocal findings on whether and how paranoid presentations relate to different personality disorders. In the...

Ghosting is a type of interpersonal rejection involving a unilateral communication interruption without explanation, using technological channels. Vulnerable narcissism and borderline traits can increase sensitivity to interpersonal rejection and reduce tolerance to ambiguity, whereas grandiose narcissism is related to low rejection sensitivity. Ye...

Pathological narcissism implies a fragile self-view. The psychological effects of ego-relevant events in people high in pathological narcissism, however, are still uncertain. The study examined the effects of pathological narcissism on psychological reactions to ego-relevant events occurring in private or public settings. Participants (N = 410) com...

Objective: Evidence suggests that pathological narcissism impacts psychotherapy process and outcome. This study investigates whether traits of pathological narcissism account for distinctiveness (construal) of patients' interpersonal perceptions in treatment settings. Methods: Patients enrolled in psychological/psychotherapeutic treatment (N = 1...

The authors investigate whether and how borderline and pathological narcissistic traits differ in their associations with trait and state rejection sensitivity, and with affective reactions to experiences of social rejection occurring in daily life. Community adults (N = 189) completed baseline measures of rejection sensitivity, borderline personal...

Numerous studies have established the importance of body image self-consciousness in predicting sexual distress and dissatisfaction in women. However, there is a dearth of information analyzing whether the same relation applies to men. Sexual perfectionism is a sexual correlate that has shown diverse links with sexual-related outcomes. The aim of t...

Dysfunctional eating attitudes and behaviors are very common among women. Recent findings suggest that these attitudes are linked to traits of pathological narcissism. However, mechanisms underlying this association need to be elucidated. We investigated the relationship between traits of pathological narcissism and dysfunctional eating attitudes a...

The Pathological Narcissism Inventory (PNI) is extensively used in recent empirical literature on pathological narcissism. However, most studies using the PNI are community-based, and no studies have used the PNI to investigate narcissistic presentations in personality disordered patients. This study investigates measurement invariance of the PNI i...

Background: COVID-19 forced healthcare workers to work in unprecedented and critical circumstances, exacerbating already-problematic and stressful working conditions.

We present here results from the baseline assessment of the “EmotionalThermometer [TermometroEmotivo] project on a sample of 1548 Italian adults. We assessed the socio-demographic co...

Background: Individuals with narcissistic traits, specifically vulnerable ones, are more prone to experiencing concerns related to self-worth and physical appearance and to showing heightened sensitivity to appearance evaluation. Negative body image and body image self-consciousness may, in turn, undermine sexual functioning, especially when appre...

Objective: Clinical theories suggest that narcissists have a compromised self-concept. However, empirical investigation on attributes of the self that would be impaired in pathological narcissism is limited and inconsistent. The present study aims at detecting distinctive profiles of narcissistic manifestations on facets of the self that have been...

During the last year, the COVID-19 outbreak put all the healthcare workers around the world at risk of physical and psychological sequelae.

Recent findings: Forty-four studies are included in this review. Between 11 and 73.4% of HCWs, mainly including physicians, nurses, and auxiliary...

The Alternative Model for Personality Disorders states that personality pathology involves significant impairment in personality functioning that can be assessed using the Level of Personality Functioning Scale (LPFS). However, the ability of the LPFS to capture impairments typical of personality pathology, rather than of general psychopathology, i...

This study investigated the association between narcissism and shame, considering different measures of narcissism, different levels of analysis, and different situational conditions. Nonclinical participants (N = 196) completed baseline measures, followed by daily questionnaires for 28 days. Multilevel models indicated that trait and daily vulnera...

Subclinical sadism has received substantial attention in recent research as a trait that predicts a variety of malevolent behaviours. The objective of this study was to assess the ‘psychometric robustness and portability’ of the Assessment of Sadistic Personality (ASP). We examined the convergent and discriminant validity, and invariance of transla...

Objective: although a large number of studies have investigated the association between non-suicidal self-injury (nssi) and personality pathology, they have adopted exclusively a categorical approach, neglecting the study of maladaptive personality functioning. the aim of the current study is to investigate whether and which dimensions of maladapti...

During the last decades, empirical interest in narcissism has steeply increased, leading to controversial findings. Its investigation has been conducted predominantly with self-report measures, which could distort empirical findings on narcissism and its correlates due to narcissists’ need to maintain a positive and inflated self-view. In the prese...

Research on personality in adolescence underlined the importance of adopting a dimensional approach to personality pathology rather than a categorical one. In this regard, the association between maladaptive versions of personality traits and pathological outcomes has been studied, neglecting the study of the severity of personality functioning. Th...

We argue that clinical information related to an object-relations model of personality pathology can be used by untrained and clinically inexperienced students to rate personality-disordered patients on the Level of Personality Functioning Scale (LPFS). To do so, 73 clinically inexperienced undergraduate students were asked to assess personality fu...

There is ongoing debate about the structure of pathological narcissism. Adopting a network approach, we investigate the core features of pathological narcissism and the nature of traits interconnections in a community sample (N= 944), considering also the effect of personality structure. Results suggest that grandiose fantasies, contingent self-est...

Narcissistic pathology is a topic of great interest for both researchers and clinicians nowadays. A growing body of research has investigated pathological narcissism to understand its nature and to reach a comprehensive definition of such personality pathology. We revised empirical and theoretical literature on pathological narcissism to show how i...

The empirical study of defence mechanisms has taken place in relative isolation, with few connections to other fields deriving from psychodynamic theories, including attachment. This study aimed to explore the associations of remembered childhood caregiving and defence mechanisms with adult attachment styles in a nonclinical sample. Furthermore, we...

Empirical literature has shown that narcissism is often associated with limited empathy, but the mechanism underlying this association is still unclear. The present study investigated the role of identity instability as a mediator of the relationship between narcissistic traits and empathic capabilities. Narcissistic traits, identity instability, a...

Objective: Whilst the relationship between narcissism and emotion regulation is a topic of great interest, little is known about the nature of this association. The aim of the present study is to clarify the relationship of both grandiose and vulnerable narcissism with difficulties in emotion regulation, controlling for the effect of borderline per...

Contemporary object-relation theory of personality postulates that the level of severity of personality organization parallels the nature and extent of problems in the patient’s sexual life. The study aims at exploring the relationship between dimensions of Borderline Personality Organization (BPO) (as assessed according to Otto Kernberg’s model),...

Gestational Trophoblastic Disease encompasses a group of pregnancy-related disorders that derive from the placenta.

Objective: Whilst the relationship between narcissism and self-esteem has been studied for a long time, findings are still controversial. The majority of studies investigated narcissistic grandiosity (NG), neglecting the existence of vulnerable manifestations of narcissism. Moreover, recent studies have shown that grandiosity traits are not always...

Objective: According to Kernberg’s psychodynamic model of personality organization (2012), identity integration, defense mechanisms and reality testing allow the classification of personality functioning in three main organizations lying on a continuum of severity. A specific relation is hypothesized to exist between the continuum of personality or...
