A better understanding of psychotherapeutic change is seen as essential for further development of treatment for personality disorders. The objective of this study is to describe the psychotherapeutic change process of a client with personality disorder to develop more insight in psychotherapeutic change processes. The change process was described quantitatively from ROM data and quantitatively and qualitatively from two narrative themes, agency and communion, described from the perspectives of client and treatment team. Reliable change analyses showed decrease in personality problems and increase in personality functioning and mental well-being. Content analyses from the client perspective showed positive changes in meaning, actual behavior change, and connection with others. The treatment team noticed growth in self-management ability and in connecting with own emotions and with others. These changes resulted in an increase in agency and communion. By mapping change processes through multiple sources and perspectives, the efficacy of psychotherapeutic treatment can be better understood.

Psychotherapy may contribute to the experience of meaning in life. This study investigated meaning in life among patients with personality disorders during inpatient or day-hospital psychotherapy. Meaning in life was approached from two conceptual perspectives: personality functioning with an emphasis on self-direction and existential psychology. We investigated changes in the sense of meaning in life and accounted for changes in depressive symptoms and identity and interpersonal pathology. Using pre-post measures, Livesley's General Assessment of Personality Disorder, especially, the Lack-of-Meaning-Purpose-and-Direction subscale and Steger's Meaning-in-Life Presence subscale were administered to 75 patients with personality disorders during inpatient or day-hospital psychotherapy for 8-12 months. Regression models showed that levels of the lack and presence of meaning decreased and increased during treatment, respectively, controlled for changes in depressive symptoms. Decreased identity pathology was significantly associated with changes in the lack or presence of meaning. Meaning in life may act as an outcome variable in intensive psychotherapy for personality disorders. The development of identity and self-direction may restore or create the ability to give life meaning.

This paper applies error management theory (EMT) (Haselton and Buss 2000) to explore how disruptions in epistemic trust-trust in communicated information-can be understood as adaptive responses to early adversity in individuals with borderline personality disorder (BPD). I propose that epistemic mistrust (EM) and epistemic credulity (EC), characterized by inappropriate trust patterns, arise from the differential costs of trusting unreliable versus mistrusting reliable information. Although these biases may seem maladaptive, they function as evolutionary survival mechanisms in response to harsh environments. Signal detection analysis can provide empirical evidence for these trust biases by assessing how individuals with BPD make trust-related decisions. Clinically, understanding these biases as evolutionary adaptations helps reduce stigma and informs evolutionary-informed interventions to recalibrate trust responses and improve interpersonal relationships. This approach highlights the significance of integrating evolutionary perspectives in treating trust disturbances in BPD.

This study examines the psychometric properties of the Latvian adaptation of the Level of Personality Functioning Scale-Self Report (LPFS-SR) and its alignment with the Alternative DSM-5 Model for Personality Disorders (AMPD). A clinical sample (N = 142) and a nonclinical sample (N = 306) were formed. Internal consistency, factor structure, and criterion validity were assessed to evaluate the scale's psychometric properties. Confirmatory factor analysis compared five structural models: one-factor, two-factor, four-factor, higher order, and bifactor. The bifactor model demonstrated the best fit, capturing both general and subscale-specific variance in personality functioning. Correlation and regression analyses explored associations between the LPFS-SR and the Personality Inventory for DSM-5 (PID-5). The findings support the Latvian LPFS-SR as a valid and reliable tool for assessing personality functioning and are consistent with the principles of the AMPD.

The stigma of personality disorder is longstanding, widespread, prodigious, and harmful. Fortunately, recent advances in our understanding of personality pathology, as well as an increasing interest in stigma, have demonstrated the importance of destigmatization and have catalyzed significant research in this area. In this special issue of Personality and Mental Health, we spotlight the stigma of personality disorders to understand the current research landscape in this area, and to chart a direction for future research. Each of the nine papers included here advances our understanding of stigma, including its manifestation, impacts, and potential solutions. Collectively, they show significant progress in the study of personality disorders stigma, support the importance of destigmatizing personality pathology, and highlight pathways for future research.

The present study examined the extent to which the currently established factor structure of the Personality Inventory for DSM-5 (PID-5; Krueger et al., 2013) generalizes to a large Persian community sample, as well as relations between the resulting PID-5 factors and two temperament measures. Cross-sectional data came from 946 adults (65% female) from western Iran. With the use of exploratory structural equation modeling (ESEM) with target rotation, we found factor loadings that showed fairly similar patterns to those found in two previous meta-analytic PID-5 studies with predominantly North American and European samples (Watters & Bagby, 2018; Somma et al., 2019). Despite slight differences in each of the target rotations, there were moderate congruence coefficients (~0.85) between loadings for the five PID-5 domains, with the weakest evidence supporting the Disinhibition factor. The resulting PID-5 factors showed meaningful associations with temperament domains assessed via the Temperament and Character Inventory (TCI; Cloninger, 1994) and Temperament Evaluation of Memphis, Pisa, Paris and San Diego-Autoquestionnaire (TEMPS-A; Akiskal et al., 2005). Overall, our findings suggest that the documented structure of personality pathology assessed by the PID-5 generalizes somewhat to this sample of Persian participants, and pathological personality traits show important overlap with temperament, although these constructs are meaningfully distinct.
