Legal, psychological, criminological, narrative and ideological representations of borderline personality disorder (BPD) are examined through 20 years of germane Canadian case law situated within the context of multidisciplinary scholarly and clinical literature on the themes of gender, mental disorder and culpability. These cases document the claim that the BPD diagnosis pathologizes women whose conduct represents adaptive responses to trauma, conflicts of selfhood and safety. A troubling sub-theme is identified in a cluster of cases where expert medical professionals are found culpable of predatory exploitation and re-victimization of patients seeking their therapeutic assistance. A third theme is the overrepresentation of BPD diagnoses in female forensic populations and the fusion of risk/need in correctional policies. It is argued that the legal deference shown to medical expertise validates BPD as a forensic category. Ultimately, the imposition of punitive corrective measures criminalizes, punishes and marginalizes this population in ways unlikely to rehabilitate and restore them to the normative order.  相似文献

Individuals with a diagnosis of personality disorder (PD) face negative attitudes and are often deemed harder to care for than individuals with other diagnoses. To improve care and engagement with services, it is essential to understand the ways general psychiatric nursing staff approach this client group. This research aims to examine the ways inpatient psychiatric nursing staff therapeutically engage with individuals with a diagnosis of PD. Focus groups were conducted with Registered Mental Health Nurses (n = 7) and Health Care Assistants (formally known as nursing assistants; n = 12) who care for individuals with a diagnosis of PD in a general psychiatric inpatient setting. A thematic analysis indicated six themes: the right frame of mind, knowing the service user, knowing when to engage, service user input, a unified approach, and structured admissions. The findings highlight what non‐PD specialist inpatient nursing staff do in order to engage therapeutically with this group of service users and areas that require improvement. Supporting good practice could improve staff confidence when caring for this client group, lower stigma around the diagnosis, and promote a more positive experience of care for individuals with a diagnosis of PD who are using general inpatient mental health services.  相似文献

Issue: Introversion is one of the personality factors that has been shown to be associated with performance in medical school. Prior cross-sectional studies highlight performance evaluation differences between introverted and extraverted medical students, though the mechanisms and implications of these differences remain relatively unexplained and understudied. This gap in the literature has become more salient as medical schools are employing more interactive learning strategies into their curricula which may disproportionately challenge introverted learners. Evidence: In this article, we provide an overview and working definition of introversion as a valid construct occurring on a continuum. We apply a goodness of fit model to explore how various medical training contexts may be more or less challenging for introverted students and the potential consequences of a poor fit. As preliminary support for these hypothesized challenges, we share observations from students self-identified as introverts. Examples include introverted students feeling at times like misfits, questioning a need to change their identity to succeed in medical school, and being judged as underperformers. We offer pragmatic suggestions for improving the fit between introverted students and their training contexts, such as teachers and students pausing between a question being asked and the initial response being offered and teachers differentiating between anxious and introverted behaviors. We conclude with suggested areas for future qualitative and quantitative research to examine how medical school curricula and the teaching environment may be differentially impacting the learning and health of introverted and extraverted students. Implications: Extraverted behaviors will continue to be an important part of medical training and practice, but the merits of introverted behaviors warrant further consideration as both medical training and practice evolve. Educators who make manageable adjustments to current teaching practices can improve the learning for both introverted and extraverted styles of academic engagement.  相似文献

Purpose

The present study investigated the validity of personality classification using four pillars theory, a tradition in China and northeastern Asia.

Materials and Methods

Four pillars analyses were performed for 148 adults on the basis of their birth year, month, day, and hour. Participants completed two personality tests, the Korean version of Temperament and Character Inventory-Revised-Short Version (TCI) and the Korean Inventory of Interpersonal Problems; scores were correlated with four pillars classification elements. Mean difference tests (e.g., t-test, ANOVA) were compared with groups classified by four pillars index.

Results

There were no significant correlations between personality scale scores and total yin/yang number (i.e., the 8 heavenly or earthly stems), and no significant between-groups results for classifications by yin/yang day stem and the five elements. There were significant but weak (r=0.18-0.29) correlations between the five elements and personality scale scores. For the six gods and personality scales, there were significant but weak (r=0.18-0.25) correlations. Features predicted by four pillars theory were most consistent when participants were grouped according to the yin/yang of the day stem and dominance of yin/yang numbers in the eight heavenly or earthly stems.

Conclusion

Although the major criteria of four pillars theory were not independently correlated with personality scale scores, correlations emerged when participants were grouped according to the composite yin/yang variable. Our results suggest the utility of four pillars theory (beyond fortune telling or astrology) for classifying personality traits and making behavioral predictions.  相似文献

This review synthesizes a wide literature on the agreement of treating clinicians’ PD diagnoses with each other and their convergence with common research methods. Median interrater reliability between clinicians was moderate when calculated dimensionally (= .46) or categorically (κ = .40). The agreement between clinicians’ diagnoses and those from research methods (e.g., self‐report questionnaire) was more modest. Median dimensional agreement across 27 studies ranged from .05 to .36, with an overall median of .23. This overall value was moderated by several factors. First, clinicians’ diagnoses agreed more with semi‐structured interviews than self‐report questionnaires. Second, convergence increased slightly when clinicians utilized more systematic diagnostic methods. Results suggest relatively little overlap between PD diagnoses assigned in research versus naturalistic settings.  相似文献

Introduction. Hallucinations in schizophrenia and hallucination proneness in healthy young adults are associated with a common cognitive mechanism, namely impaired inhibitory control. Hallucinatory-like experiences also seem related to hypomanic symptoms in non-clinical participants; however, the mechanisms involved are unknown. We sought to examine self-reported hallucinatory/anomalous perceptual experiences in students selected for high versus low levels of hypomanic personality traits, and whether hypomania is characterised by deficient inhibitory control.

Method. Undergraduate students with either high (n = 26) or low (n = 28) scores on the Hypomanic Personality Scale-Revised (HPS-20) were compared on: (1) the Launay Slade Hallucination Scale-Revised (LSHS-R), a measure of hallucination proneness, (2) the Cardiff Anomalous Perceptions Scale (CAPS) and (3) the Inhibition of Currently Irrelevant Memories (ICIM) task, an index of intentional inhibition.

Results. The high HPS group had higher total scores, as well as higher frequency (on CAPS only), intrusiveness and distress (CAPS) scores compared to the low HPS group. They also produced significantly more false alarms on the second run of the ICIM task than the low hypomania traits group.

Conclusions. Frequent, intrusive and distressing perceptual anomalies and proneness to hallucinations tend to occur in healthy individuals with hypomanic personality traits and may be associated with transient difficulties with inhibitory control. Inhibitory control may be a cognitive marker of vulnerability to hallucinations across diagnostic boundaries.  相似文献
