Previous research on self-informant reports in assessing personality disorders (PDs) has been mainly focused on adults, leaving older adults under-studied. We examined self-informant agreement in PD screening among older adults (≥60 years) using the Gerontological Personality disorders Scale (GPS). Potential differences such as who reports more personality pathology on a PD screener (i.e., GPS), item accessibility and the effect of relational aspects were studied as well. Data of 326 older adult-informant dyads, of which the older adults were sampled from five general practices in the Netherlands, were used. Results indicate that self-informant agreement ranged from r = 0.26-0.73, with lower concordance on the GPS-subscale measuring intrapersonal aspects of personality pathology. Informants were more sensitive to habitual pathological personality features than older adults. Two GPS items showed differential item functioning across self- and informant-report. Of relational aspects, only congeniality affected the GPS-iv scores; lower ratings on congeniality were associated with higher GPS-iv scores (i.e., higher reporting of personality problems).

Research has shown that severity of depression increased in freshmen during their first months at university due to increased social and academic pressures. Since the start of the COVID-19 pandemic, several cross-sectional studies have suggested that levels of depression in university students are higher than before the pandemic, but longitudinal data are largely lacking. This study investigated severity of depression and negative affect linked to the pandemic among freshmen during their first semester at a large university in Flanders, Belgium. We also investigated whether epistemic trust predicted severity of depression and pandemic-related negative affect and whether problems with reflective functioning (or mentalizing) mediated these relations. Participants in this two-wave prospective study were 289 first-year students of the Faculty of Psychology and Educational Sciences of a large Belgian university. We conducted paired samples t-tests and cross-panel analysis to answer the research question. The number of students at risk of clinical depression increased by 41% between T1 (early October 2020) and T2 (late December 2020). Epistemic mistrust at T1 was prospectively associated with an increase in the prevalence and severity of depression at T2. Problems with mentalizing and negative COVID-19-related affect were positively associated with severity of depression at T2 and mediated the association between epistemic mistrust and severity of depression at T2. The findings highlight the key role of epistemic trust in the development of depression among freshmen, with the COVID-19 pandemic presenting an additional source of uncertainty.

The current study examined the psychometric properties of the Proposed Specifiers for Conduct Disorder (PSCD) in a sample of school-attending adolescent Belgian youth (N = 599; M age = 16.51 years, SD = 1.27). Given the recent interest in the PSCD-Short Version (PSCD-SV), this study focused on the 13-item variant of the PSCD. Study findings showed that the PSCD-SV had a hierarchical four-factor structure including the components of grandiose-manipulative (GM), callous-unemotional (CU), daring-impulsive (DI), and conduct disorder (CD). These interrelated factors were found to be internally consistent. The study also showed that the PSCD-SV total score was positively and significantly related to an alternate measure of psychopathy. Further, the study revealed the PSCD-SV was meaningfully related to the five-factor personality domains (i.e., extraversion, conscientiousness, agreeableness) as well as peer functioning and prosocial behavior. Bivariate correlations demonstrated that the dimensions differed in their associations with external correlates (e.g., peer functioning). Regression analyses showed that the GM, CU, and CD components of the PSCD-SV were uniquely associated to externalizing difficulties, whereas only the GM and CU components of the PSCD-SV were associated with low prosocial behaviors. These findings shed light on the conceptual and developmental models for the consideration of psychopathy and conduct problems. The use of the broader psychopathy condition as well as its underpinning dimensions may have important implications for assessment, treatment, and diagnostic manuals. The implications of the current study are further discussed.

Poor quality sleep is common for people who have a diagnosis of personality disorder (PD). Core cognitive and behavioral features of PD may cause and perpetuate poor sleep, but to date, no review has collated the evidence on the efficacy of interventions to improve sleep quality for people with PD. Structured searches for interventional studies among adults with PD and reporting validated measures of sleep quality were conducted up to November 2022 in multiple databases. Single-case reports were excluded. Study quality was assessed with standardized risk of bias tools. Unreported data was sought systematically from authors. This review was pre-registered with an international prospective register of systematic reviews (PROSPERO) (CRD42021282105). Of the 3503 identified studies, nine met inclusion criteria, representing a range of psychological, pharmaceutical, and other interventions and outcome measures. Meta-analytic methods were not feasible because of the serious risk of bias in all studies, and results were therefore synthesized narratively. There is limited and low-quality evidence of the effects of a variety of interventions to improve the sleep quality of people living with PD. Further research might consider specifically including people diagnosed with PD in trials of sleep interventions and using sleep outcome measures in trials of established PD treatments.

This study investigated the relative efficacy of Mentalization-based therapy (MBT) and United Protocol (UP) in reducing symptoms of psychopathy and emotion dysregulation in a sample of Iranian community residents with concurrent diagnoses of antisocial and borderline personality disorders (PDs). Interpersonal, affective, and lifestyle features of psychopathy were measured post-treatment and at 6-, 12-, 18-, 24-, and 36-months follow-up using the 13-item version of the Psychopathy Revised-Checklist (PCL-R), which excluded, by design, criminal history features. Emotion dysregulation was measured using the Deficits in Emotion Regulation Scale (DERS) developed by Gratz and Roemer (2004). After treatment, both UP- and MBT-treated individuals showed significantly fewer features of psychopathy and significantly less emotion dysregulation. Compared with those treated with MBT, UP-treated individuals showed significantly less emotion dysregulation in all DERS subscales and a greater reduction in psychopathy features, particularly affective features. It is suggested that this likely reflected the particular emphasis placed by UP on improving emotional self-regulation and facilitating the therapeutic alliance. These results suggest that, despite the traditional pessimism that surrounds psychopathic individuals' treatability, they can be successfully treated.

No clinician-rating tool has formally been developed to assess the ICD-11 model of personality disorder (PD) severity. We therefore developed and evaluated the 14-item personality disorder Severity ICD-11 (PDS-ICD-11) Clinician-Rating Form. A combined sample of 195 patients was rated by mental health professionals or clinical research assistants in New Zealand using the PDS-ICD-11 Clinician-Rating Form. Responses were subjected to item-response theory analysis and confirmatory factor analysis. In a subsample, we examined interrater reliability and convergence with self- and informant-reported measures of personality impairment, dysfunction in various psychopathology domains, and traditional PD symptoms. Item-response theory and confirmatory factor analyses supported the item functioning and unidimensionality, respectively, of the PDS-ICD-11 Clinician-Rating Form. The interrater reliability was very promising (intraclass correlation coefficient = 0.94, p < 0.001). PDS-ICD-11 Clinician-Rating Form scores were associated with established measures of personality dysfunction at large effect sizes. This initial development study suggests that the PDS-ICD-11 Clinician-Rating Form constitutes a psychometrically sound instrument that provides a clinically based impression of the severity of personality dysfunction according to the official ICD-11 description. More research is needed to corroborate its validity and utility, and a structured interview is warranted for diagnostic purposes. The final PDS-ICD-11 Clinician-Rating Form is included as online supporting information.

Objective: Targeting self-criticism, the tendency to negatively evaluate and judge aspects of oneself, may improve treatment efficacy for personality disorders (PDs). This study aimed to test whether adding 12-week group compassion-focused therapy (CFT) that explicitly targets self-criticism to treatment as usual (TAU) would reduce self-criticism in patients with PDs.

Method: Twelve patients with PDs participated in a multiple baseline study, randomly allocated to different baseline lengths. The primary outcome was twice-weekly assessed self-critical beliefs during baseline, treatment, and follow-up phases. Secondary outcomes were self-criticism, self-compassion, and PD severity at the end of CFT and follow-up (trial registered: NL8131). Nine participants completed the intervention. No significant changes were observed during CFT, but at follow-up significant decrease in self-critical beliefs (Cohen's d = -0.43; 95% CI = -0.73 to -0.12) was reported compared to baseline. On secondary outcomes, most participants showed reliable improvement on self-reported criticism (66.7%) and self-compassion (55.6%), and a minority of patients showed reliable improvement in PD severity (33.3%).

Conclusions: This study seems to provide preliminary evidence for the effectiveness of 12-week CFT for self-critical beliefs in patients with PDs compared to TAU. CFT for self-criticism in PDs may complement treatment offerings and warrant further research.

This study assessed the effect of a mentalisation-based therapy (MBT) treatment programme on the utilisation of Western Australian public hospitals for mental health presentations over an 18-month period. Hospital data included the number of visits to the emergency department (ED), the number of inpatient admissions to hospital and length of stay of the admissions. Participants included 76 adolescents aged 13-17 years old, who presented with borderline personality disorder (BPD) traits. The Touchstone treatment programme is a time-limited intensive programme that utilises MBT in the context of a therapeutic community. Hospital data for the participants were collected and analysed from three time points; 6 months prior to attending the programme, during the 6-month programme (active treatment) and 6 months after the programme. Results found a statistically significant decrease in hospital utilisation from pre to post programme, with a decline in ED visits, inpatient admissions and admission length of stay. This study presents promising preliminary evidence for the effectiveness of an intensive MBT programme as an intervention for adolescents with BPD features and has significant implications for the public health system in terms of providing effective community-based treatment for this difficult to treat population as well as reducing pressure on tertiary care.

This study aimed to understand the role of disinhibition (low conscientiousness)-in conjunction with the other major personality traits of negative affectivity, detachment, antagonism, and psychoticism-in predicting changes in depressive symptoms and psychosocial functioning. Both the disinhibition trait domain and its primary facets (i.e., irresponsibility, impulsivity, and distractibility) were examined. In a large sample (Time 1 N = 605, Time 2 N = 497) of psychiatric outpatients and high-risk community residents, personality traits, depressive symptoms (both self-reported and interviewer-rated), and psychosocial functioning levels (i.e., daily functioning, interpersonal functioning, health-related quality of life, and global quality of life) were collected across two time points. Results showed that the disinhibition domain was the strongest predictor of changes in depressive symptoms and general quality of life levels. Disinhibition facets also predicted changes in depressive symptoms but showed a less consistent pattern compared to the broader trait domain. Finally, the irresponsibility and distractibility facets significantly and uniquely explained changes in interpersonal functioning. The study highlights the importance of assessing the disinhibition trait rather than only negative and positive affectivity (which are well-known correlates of depression), for understanding changes in depressive symptoms and psychosocial functioning. The findings identify potential targets in psychotherapy for individuals with disinhibition traits and depressive disorders.
