The existing literature suggests that these tools struggle to accurately measure personality pathology among these groups. Scholars have hypothesized this difficulty is partly due to instruments failing to consider the effects of minority stress on personality pathology. The current study examined differences between SGM and cis-hetero individuals on the Level of Personality Functioning Scale-Brief Form 2.0 using item response theory (IRT) differential item functioning (DIF) analyses. DIF clarifies whether item endorsement is a function of similar levels of personality functioning as well as how effectively items distinguish among individuals across personality functioning severity. To complement these analyses, we also computed traditional difference testing. Participants were a sample of 1,238 community members that include both SGM and cis-hetero individuals. There was no compelling evidence of significant DIF across groups. Findings demonstrate that the Level of Personality Functioning Scale-Brief Form 2.0 items function similarly across SGM and cis-hetero individuals. That said, traditional difference testing showed three instances of statistically significant differences between the SGM and cis-hetero subgroups. These findings suggest there is a modest difference in personality functioning across groups that is not attributable to measurement bias. We discuss potential factors influencing the observed pattern of results that require further study, as well as practical concerns for clinicians using these tools to assess SGM clients.

Six databases (CINAHL, EMBASE, EMCare, MEDLINE, PsycINFO, and PubMed) were searched for studies assessing Criterion A and ASPD, aggression, antisocial behavior, and/or psychopathy. Thirty-two studies were identified. Meta-analysis revealed strong pooled associations between self-report and clinician-rated LPFS measures and Section II ASPD. Effects with psychopathy for self-report LPFS measures were moderate and weak for clinician-rated LPFS. Weak to moderate pooled effects for LPFS with aggression and antisocial behavior were found. ASPD-specific impairments showed moderate associations with Section II ASPD and large associations for psychopathy. Overall, general and ASPD-specific measures demonstrated variable criterion validity with Section II ASPD and associated antisocial constructs. Caution is warranted when assessing Criterion A impairment for antisociality using a single measure in isolation. A clinician-led, multimethod approach that integrates general LPFS-based assessment with instruments specifically designed to capture antisocial features is likely to (a) enhance diagnostic accuracy and (b) improve the clinical utility of Criterion A assessment in informing violence risk formulation and management.

Traditionally associated with borderline personality disorder, subjective emptiness is increasingly recognized as a transdiagnostic construct linked to adverse clinical outcomes and substantial psychosocial impairment. Despite its relevance, specific instruments for assessing this construct remain scarce. To address this gap, Price et al. (2022) developed the Subjective Emptiness Scale (SES), a five-item self-report measure designed to capture the core features of emptiness. Study 1 examined the psychometric properties of the Italian version of the SES in a nonclinical sample of 1,204 participants (71.3% female; <i>M</i><sub>age</sub> = 30.79, <i>SD</i> = 11.31). Study 2 aimed to replicate these findings in a clinical sample of 177 individuals diagnosed with personality disorders (56% female; <i>M</i><sub>age</sub> = 33.22, <i>SD</i> = 11.71). Results from both studies indicated that the Italian version of the SES demonstrated a stable unidimensional structure, full measurement invariance across sex, and good internal consistency across general and clinical populations. SES scores also exhibited the expected pattern of correlations with conceptually related constructs. However, its incremental validity beyond depressive symptoms appeared questionable, suggesting a substantial overlap between subjective emptiness and depression-related experiences. Accurate assessment of subjective emptiness may contribute to a more refined understanding of its role as a central psychological mechanism in personality pathology and inform the development of targeted interventions, ultimately improving treatment outcomes. Future research should clarify the conceptual and empirical boundaries between emptiness and depression to improve measurement precision.

Factor analyses revealed a three-factor structure: Feelings of Inner Emptiness, Absence of Relatedness, and Meaninglessness. Narrative analysis supported this structure. Experiences of emptiness were often described in physical terms and varied in frequency, chronicity, and triggers. Feelings of Inner Emptiness were strongly associated with identity disturbances, personality dysfunction, and greater engagement in self-harm and disordered eating. Furthermore, emptiness was linked to greater use of externalizing and distancing coping strategies, alongside adaptive strategies such as seeking support. These findings offer a more nuanced understanding of emptiness beyond clinical populations and highlight its connections to self- and interpersonal dysfunction, engagement in internalizing health risk behaviors, and avoidance-focused coping strategies.

Three individual criteria (detail-oriented, inflexible, overconscientious, and scrupulous, and miserly spending style) were shown to be stable while the other five (perfectionism, reluctance to delegate, rigidity and stubbornness, excessive work devotion, and inability to discard) were unstable. OCPD diagnosis ratings generally remained stable with some decrease over time in individuals with OCD and consist of a mix of enduring and episodic symptom criteria.
