RESUMEN

Both the new ICD-11 and the latest Alternative DSM-5 Model for Personality Disorders focus on self and interpersonal functioning as the central feature of personality pathology, also acknowledging that personality disorders are organized along a dimensional continuum of severity. This revised understanding is in line with long-standing psychodynamic conceptualisations of personality pathology, in particular Kernberg's object relations model of personality organization. Despite existing evidence for the clinical utility of the derived Structured Interview of Personality Organization (STIPO-R), empirical support for the identification of clear cut-points between the different levels of personality functioning is missing. For this purpose, a total of 764 adult participants were recruited across two clinical (outpatient and inpatient) settings (n = 250) and two non-clinical (university students and general community) samples (n = 514). Results from the mixture modeling suggested the existence of five groups across the clinical and non-clinical samples that covered: healthy personality functioning, maladaptive personality rigidity, and mild, moderate, and severe levels of personality pathology. All five indicators of personality organization were found to be reliable predictors of personality pathology. Of the five STIPO-R indicators, Aggression and Moral Values had the most discriminative power for differentiating between the Mild, Moderate, and Severe personality disorder groups. Implications of these findings are discussed.

RESUMEN

Transference-focused psychotherapy (TFP) is an empirically supported treatment for borderline personality disorder (BPD) that improves functioning via targeting representations of self affectively relating to others, particularly as evoked in the therapeutic relationship. If change in TFP operates as theorized, then shifts in patterns of "self affectively relating to others" should be observed in the transference prior to shifts in daily relationships. Using ecological momentary assessment (EMA), a patient with BPD rated daily interpersonal events for 2-week periods during 18 months of TFP; at 9 and 18 months these ratings included interactions with the therapist. Results suggest that positive perceptions of her therapist that ran counter to her negatively biased perception in other relationships preceded changes in her perceptions of others. EMA shifts corresponded to improvements in self-reported symptoms, interview-based personality functioning, and therapist assessments. Implications for assimilation of a trusting experience with the therapist as a mechanism of change in TFP are discussed.

RESUMEN

BACKGROUND: Psychiatric patients are subjected to considerable stigmatization, in particular, because they are considered aggressive, uncontrollable, and dangerous. This stigmatization might influence the approval of coercive measures in psychiatry by the public and healthcare professionals and might have an influence on the clinical practice of coercive measures. We examined whether the general approval of coercive measures for psychiatric patients with dangerous behaviors differs from case-specific approval. METHOD: We conducted a representative survey of the general population (n = 2207) in the canton of Basel-Stadt, Switzerland. In total, 1107 participants assessed a case vignette depicting a fictitious character with a mental illness and indicated whether they would accept coercive measures (involuntary hospitalization, involuntary medication, and seclusion) for the person in the vignette. It was explicitly stated that within the last month, the fictitious character displayed no dangerous behavior (Vignette ND) or dangerous behavior (Vignette D). Another 1100 participants were asked whether they would approve coercive measures (involuntary hospitalization, involuntary medication, and seclusion) for psychiatric patients with dangerous behavior in general (General D), i.e., without having received or referring to a specific case vignette. FINDINGS: The logistic regression model containing all variables explained 45% of the variance in approval of any type of coercive measures. Assessment of case vignettes without dangerous behavior (Vignette ND) was associated with significantly reduced approval of coercive measures compared to assessment of a case vignette with dangerousness (Vignette D), while approval for coercive measures in a person with mental health disorder with dangerous behavior in general (General D) was significantly higher than for the case vignette with dangerousness. CONCLUSIONS: The general approval of coercive measures for people with mental disorders seems to differ depending on if the respondents are asked to give a general assessment or to examine a specific and detailed clinical case vignette, indicating an increased role of stigmatization when asking about generalized assessments. This may contribute to diverging findings on the acceptance of coercive measures in the literature and should be considered when designing future studies.

RESUMEN

Contemporary models of the diagnosis and classification of personality disorders have diverged from the categorical diagnostic framework of the DSM system. One response to this movement can be found in the Alternative DSM-5 Model for Personality Disorders (AMPD), which uses dimensions of personality functioning, coupled with identification of dominant pathological traits, to define and classify personality disorders. By applying psychodynamic object relations theory to the AMPD, therapists can enrich the understanding and assessment of personality functioning and pathology as described in the AMPD.

RESUMEN

BACKGROUND: Impaired reflective functioning (RF) is common among patients with borderline personality disorder (BPD). Transference-focused psychotherapy (TFP) has been demonstrated to improve RF compared to other common BPD treatments. If RF reflects a treatment mechanism for TFP, differences in pretreatment RF may also serve as a prescriptive factor for TFP's effects. METHOD: A total of 194 patients with BPD were randomized across two clinical trials to receive TFP (n = 83), dialectical behavior therapy (DBT; n = 31), supportive psychodynamic therapy (SPT; n = 28), or an enhanced treatment as usual (eTAU; n = 52). A mixed-effects model was used to examine whether baseline RF interacted with treatment condition to predict slopes of change in the Brief Symptom Inventory, the shared symptom outcome between trials. Moderation of changes in RF was also examined. RESULTS: Treatment interacted with baseline RF to predict BSI slopes (p = .011). In TFP/SPT, RF did not predict outcomes, ß = -0.00, p = .973, while higher RF was associated with relatively better outcomes in DBT/eTAU, ß = -0.54, p < .001. Patients with poor RF (scores of 0/1) benefitted more from TFP/SPT, while patients with relatively ordinary RF (score of 4) had better outcomes in DBT/eTAU. Treatment effects on RF change were also moderated by baseline RF (p = .014), such that TFP improved RF most strongly among poor RF patients, SPT only among very poor RF patients, and DBT/eTAU not at all. DISCUSSION: Low RF may reflect a deficit that may be targeted by TFP and other manualized psychodynamic treatments for BPD, which may be especially helpful among patients presenting with low RF.

RESUMEN

There has been little research exploring the relationship between personality traits, self-esteem, and stigmatizing attitudes toward those with mental disorders. Furthermore, the mechanisms through which the beholder's personality influence mental illness stigma have not been tested. The aim of this study is to examine the relationship between Big Five personality traits, self-esteem, familiarity, being a healthcare professional, and stigmatization. Moreover, this study aims to explore the mediating effect of perceived dangerousness on the relationship between personality traits and desire for social distance. We conducted a vignette-based representative population survey (N = 2207) in the canton of Basel-Stadt, Switzerland. Multiple regression analyses were employed to examine the associations between personality traits, self-esteem, familiarity, and being a healthcare professional with the desire for social distance and perceived dangerousness. The mediation analyses were performed using the PROCESS macro by Hayes. Analyses showed associations between personality traits and stigmatization towards mental illness. Those who scored higher on openness to experience (ß = - 0.13, p < 0.001), (ß = - 0.14, p < 0.001), and those who scored higher on agreeableness (ß = - 0.15, p < 0.001), (ß = - 0.12, p < 0.001) showed a lower desire for social distance and lower perceived dangerousness, respectively. Neuroticism (ß = - 0.06, p = 0.012) was inversely associated with perceived dangerousness. Additionally, high self-esteem was associated with increased stigmatization. Personal contact or familiarity with people having mental disorders was associated with decreased stigmatization. Contrarily, healthcare professionals showed higher perceived dangerousness (ß = 0.04, p = 0.040). Finally, perceived dangerousness partially mediated the association between openness to experience (indirect effect = -  .57, 95% CI [- .71, - 0.43]) as well as agreeableness (indirect effect = - 0.57, 95% CI [- 0.74, - 0.39]) and desire for social distance. Although the explained variance in all analyses is < 10%, the current findings highlight the role of personality traits and self-esteem in areas of stigma. Therefore, future stigma research and anti-stigma campaigns should take individual differences into consideration. Moreover, the current study suggests that perceived dangerousness mediates the relationship between personality traits and desire for social distance. Further studies are needed to explore the underlying mechanisms of such relationship. Finally, our results once more underline the necessity of increasing familiarity with mentally ill people and of improving the attitude of healthcare professionals towards persons with mental disorders.

RESUMEN

Recent advances in the understanding of personality pathology have contributed to an emphasis on the core of personality pathology as deficits in self-functioning and interpersonal functioning at different levels of severity that must be assessed for clinical intervention. In concert with these conceptual and empirical advances, transference-focused psychotherapy (TFP), an empirically supported psychodynamic treatment for borderline personality disorder, has been in constant development with extensive clinical use. This article describes an object relations model for conceptualizing and assessing levels of personality organization, a transdiagnostic approach to personality pathology, and related treatment modifications, thus expanding the utilization of TFP beyond borderline personality disorder to the full range of personality dysfunction. The core of this treatment approach is a sequential interpretive process between patient and therapist. This process takes place within the context of a structured treatment frame tailored to the unique individual with problems in self-functioning and interpersonal functioning in his/her particular environment.

RESUMEN

Background: Coercion is routinely used in psychiatry. Its benefits and drawbacks are controversially debated. In addition, the majority of persons with mental health problems are exposed to stigmatization and are assumed to be dangerous. Stigmatization is associated with negative consequences for individuals with mental illness such as disapproval, social rejection, exclusion, and discrimination. Being subjected to coercive measures can increase the stigmatization of the affected persons, and stigmatization might lead to higher approval for coercion. Aims of the Study: This study aims to examine the approval for coercive measures in psychiatry by the general public, and to explore its relation with person- and situation-specific factors as well as with stigmatization. Method: We conducted a representative survey of the general population (N = 2,207) in the canton of Basel-Stadt, Switzerland. Participants were asked to read a vignette depicting psychopathological symptoms of a fictitious character and indicate whether they would accept coercive measures for the person in the vignette. Desire for social distance and perceived dangerousness were assessed as measures of stigmatization. Findings: The person in the case vignette exhibiting dangerous behavior, showing symptoms of a psychotic disorder, being perceived as dangerous, and treatment being understood as helpful increased approval of coercion in general, while familiarity of the respondents with mental illness decreased approval. Conclusions: The public attitude regarding the approval of coercion in psychiatry is highly differentiated and largely follows the current legal framework and medical treatment guidelines. Higher approval occurred in situations of self-harm or harm to others and when coercive measures were thought to have a beneficial effect for the affected persons. A considerable part of the approval for coercion is predicted by stigmatization. With the increasing severity of coercive measures, the influence of person- and situation-specific factors and of familiarity with mental illness decreased and generalizing and stigmatizing attitudes became stronger predictors for the approval of more severe measures.

RESUMEN

The Alternative Model of DSM-5 combines dimensional ratings of self-functioning, interpersonal functioning, and traits with categorical classification. The object relations model has a long tradition pre-dating the Alternative Model and, in part, has been incorporated into the Alternative Model. The object relations model provides a theoretical background (generally missing in the Alternative Model) that enhances the clinical assessment of personality pathology and its relationship to treatment planning.

RESUMEN

Background: Aggression in psychoses is of high clinical importance, and volumetric MRI techniques have been used to explore its structural brain correlates. Methods: We conducted a systematic review searching EMBASE, ScienceDirect, and PsycINFO through September 2017 using thesauri representing aggression, psychosis, and brain imaging. We calculated effect sizes for each study and mean Hedge's g for whole brain (WB) volume. Methodological quality was established using the PRISMA checklist (PROSPERO: CRD42014014461). Results: Our sample consisted of 12 studies with 470 patients and 155 healthy controls (HC). After subtracting subjects due to cohort overlaps, 314 patients and 96 HC remained. Qualitative analyses showed lower volumes of WB, prefrontal regions, temporal lobe, hippocampus, thalamus and cerebellum, and higher volumes of lateral ventricles, amygdala, and putamen in violent vs. non-violent people with schizophrenia. In quantitative analyses, violent persons with schizophrenia exhibited a significantly lower WB volume than HC (p = 0.004), and also lower than non-violent persons with schizophrenia (p = 0.007). Conclusions: We reviewed evidence for differences in brain volume correlates of aggression in persons with schizophrenia. Our results point toward a reduced whole brain volume in violent as opposed to non-violent persons with schizophrenia. However, considerable sample overlap in the literature, lack of reporting of potential confounding variables, and missing research on affective psychoses limit our explanatory power. To permit stronger conclusions, further studies evaluating structural correlates of aggression in psychotic disorders are needed.

RESUMEN

BACKGROUND: Little is known about narcissistic traits in borderline personality disorder (BPD). This exploratory study aimed to illustrate the associations between total, grandiose, and vulnerable narcissism and gender, diagnostic features of BPD and narcissistic personality disorder (NPD), and psychopathology in BPD patients. SAMPLING AND METHODS: The Pathological Narcissism Inventory and psychometric measures for impulsivity, anger, borderline symptom severity, personality organization, depression, and rejection sensitivity were completed by 65 BPD patients. Statistical analyses were conducted using the t test, Pearson correlation, and multivariate regression analyses. RESULTS: Male BPD patients displayed higher narcissistic scores than females (p < 0.01). Grandiose narcissism showed a stronger association with NPD than with BPD (p < 0.01) while vulnerable narcissism was only associated with BPD (p < 0.01). Rejection sensitivity (p < 0.01) and depression (p < 0.001) predicted vulnerable narcissism. CONCLUSION: Vulnerable narcissism is closely associated with BPD and appears to be more dysfunctional than grandiose narcissism. A comprehensive consideration of both traits is recommended. Our results might help to generate hypotheses for further research on pathological narcissism in the spectrum of personality disorders. Future studies are advised to apply complementary measures and take new diagnostic approaches of DSM-5 and ICD-11 into account.

RESUMEN

Perceptions of dangerousness are an influential component of mental health stigma and can be driven by the display of psychiatric symptoms and the use of psychiatric service institutions. Yet, no previous study compared symptoms and service use associated perceptions of dangerousness. Therefore, we conducted a representative survey (N = 2,207) in the canton of Basel-Stadt, Switzerland. Participants were asked to answer the perceived dangerousness scale with respect to a vignette that either depicted psychiatric symptoms of a fictitious character or a psychiatric service institution the fictitious character had been admitted to. Between the vignettes, type of symptoms, type of psychiatric service, dangerousness, and gender were systematically varied. Perceived dangerousness was significantly lower as related to psychiatric service use than related to psychiatric symptoms. Overall, symptoms of alcohol dependency, behavior endangering others, and male gender of the fictitious character tend to increase perceived dangerousness. Furthermore, being hospitalized in a psychiatric unit at a general hospital or the rater being familiar with psychiatric services tends to decrease perceived dangerousness. Effective anti-stigma initiatives should integrate education about dangerousness as well as methods to increase familiarity with psychiatry. Additionally, an integration of modern psychiatry in somato-medical care institutions might decrease stigmatization.

RESUMEN

RATIONALE: An ongoing debate concerns acceptability, benefits, and shortcomings of coercive treatment such as assisted outpatient treatment (AOT). The hypothesis that involuntary commitment to outpatient treatment may lead to a better clinical outcome for a subgroup of persons with severe mental illness (SMI) is controversial. Nonetheless, positive effects of AOT may be mediated by an increased availability of healthcare resources or increased service use. OBJECTIVE: The purpose of the present study is to evaluate the course of delusions, hallucinations, and negative symptoms among patients with SMI receiving AOT compared to patients receiving non-compulsory treatment (NCT). Moreover, we assessed if the effects of AOT on psychotic symptoms were mediated by increased healthcare service use. METHODS: This study used a quasi-experimental design to examine the effect of AOT and the use of healthcare services on psychotic symptoms. In total, 76 (41.3%) participants with SMI received AOT, and 108 (58.7%) received NCT. The participants were interviewed at baseline every 3 months up to 1 year. Propensity score matching was used to control for group differences. RESULTS: In the basic model, AOT was associated with lower severity of psychotic symptoms over all follow-up points. In the model including healthcare service use, the frequency of case manager visits predicted a reduction in severity of all psychotic symptoms. The frequency of visits to the outpatient clinics, frequency of emergency room, and psychiatrist visits were independently associated with lower levels of delusional symptoms. Psychiatrist visits were related to a decrease in negative symptoms. CONCLUSION: Results indicate that the treatment benefits of AOT are enhanced with the increased use of mental healthcare services, suggesting that the positive effect of AOT on psychotic symptoms is related to the availability of mental healthcare service use. Coercive outpatient treatment might be more effective through greater use of intensive services.

RESUMEN

Background There is evidence for two different types and/or sources of mental illness stigma, namely the display of psychiatric symptoms and the use of psychiatric service institutions. However, no current study has compared the two. Furthermore, gaps exist in our knowledge of both types of stigma. Little is known about the perceived stigma of specific psychiatric service treatment environments, for instance forensic settings. In addition, systematic research on stigma attached to symptoms of personality disorders in the general population is scarce, and for borderline personality disorder, nonexistent. Methods We conducted a representative survey of the general population (N = 2207) in the canton of Basel-Stadt, Switzerland. Participants were asked to read a vignette depicting either the psychiatric symptoms of a fictitious character or a psychiatric service institution to which the character had been admitted, and indicate desired social distance (an indicator for stigma). Type of symptoms, type of psychiatric service, dangerousness, and gender were systematically varied between vignettes. Findings Desired social distance was significantly lower in relation to psychiatric service use than to psychiatric symptoms. Overall, symptoms of alcohol dependency, behavior endangering others, and the fictitious character's being male tend to increase stigmatization. Interestingly, the character's being hospitalized in a psychiatric unit at a general hospital and also respondent familiarity with psychiatric services tend to decrease stigmatization. Interpretation Familiarity of the general population with psychiatric patients should be increased. Furthermore, treatment in psychiatric units located within general hospitals should be promoted, as such treatment is associated with decreased stigma.

RESUMEN

A growing body of longitudinal studies suggests that low self-esteem is a risk factor for depression. However, it is unclear whether other characteristics of self-esteem, besides its level, explain incremental or even greater variance in subsequent depression. We examined the prospective effects of self-esteem level, instability (i.e., the degree of variability in self-esteem across short periods), and contingency (i.e., the degree to which self-esteem fluctuates in response to self-relevant events) on depressive symptoms in 1 overarching model, using data from 2 longitudinal studies. In Study 1, 372 adults were assessed at 2 waves over 6 months, including 40 daily diary assessments at Wave 1. In Study 2, 235 young adults were assessed at 2 waves over 6 weeks, including about 6 daily diary assessments at each wave. Self-esteem contingency was measured by self-report and by a statistical index based on the diary data (capturing event-related fluctuations in self-esteem). In both studies self-esteem level, but not self-esteem contingency, predicted subsequent depressive symptoms. Self-esteem instability predicted subsequent depressive symptoms in Study 2 only, with a smaller effect size than self-esteem level. Also, level, instability, and contingency of self-esteem did not interact in the prediction of depressive symptoms. Moreover, the effect of self-esteem level held when controlling for neuroticism and for all other Big Five personality traits. Thus, the findings provide converging evidence for a vulnerability effect of self-esteem level, tentative evidence for a smaller vulnerability effect of self-esteem instability, and no evidence for a vulnerability effect of self-esteem contingency.

RESUMEN

Low self-esteem and depression are strongly related, but there is not yet consistent evidence on the nature of the relation. Whereas the vulnerability model states that low self-esteem contributes to depression, the scar model states that depression erodes self-esteem. Furthermore, it is unknown whether the models are specific for depression or whether they are also valid for anxiety. We evaluated the vulnerability and scar models of low self-esteem and depression, and low self-esteem and anxiety, by meta-analyzing the available longitudinal data (covering 77 studies on depression and 18 studies on anxiety). The mean age of the samples ranged from childhood to old age. In the analyses, we used a random-effects model and examined prospective effects between the variables, controlling for prior levels of the predicted variables. For depression, the findings supported the vulnerability model: The effect of self-esteem on depression (ß = -.16) was significantly stronger than the effect of depression on self-esteem (ß = -.08). In contrast, the effects between low self-esteem and anxiety were relatively balanced: Self-esteem predicted anxiety with ß = -.10, and anxiety predicted self-esteem with ß = -.08. Moderator analyses were conducted for the effect of low self-esteem on depression; these suggested that the effect is not significantly influenced by gender, age, measures of self-esteem and depression, or time lag between assessments. If future research supports the hypothesized causality of the vulnerability effect of low self-esteem on depression, interventions aimed at increasing self-esteem might be useful in reducing the risk of depression.

RESUMEN

CONTEXT: Schizophrenia is the collective term for a heterogeneous group of mental disorders with a still obscure biological basis. In particular, the specific contribution of risk or candidate gene variants to the complex schizophrenic phenotype is largely unknown. OBJECTIVE: To prepare the ground for a novel "phenomics" approach, a unique schizophrenia patient database was established by GRAS (Göttingen Research Association for Schizophrenia), designed to allow association of genetic information with quantifiable phenotypes.Because synaptic dysfunction plays a key role in schizophrenia, the complexin 2 gene (CPLX2) was examined in the first phenotype-based genetic association study (PGAS) of GRAS [corrected] DESIGN: Subsequent to a classic case-control approach, we analyzed the contribution of CPLX2 polymorphisms to discrete cognitive domains within the schizophrenic population. To gain mechanistic insight into how certain CPLX2 variants influence gene expression and function, peripheral blood mononuclear cells of patients, Cplx -null mutant mice, and transfected cells were investigated. SETTING: Coordinating research center (Max Planck Institute of Experimental Medicine) and 23 collaborating psychiatric centers all over Germany. PARTICIPANTS: One thousand seventy-one patients with schizophrenia (DSM-IV) examined by an invariant investigator team, resulting in the GRAS database with more than 3000 phenotypic data points per patient, and 1079 healthy control subjects of comparable ethnicity. Main Outcome Measure Cognitive performance including executive functioning, reasoning, and verbal learning/memory. RESULTS: Six single-nucleotide polymorphisms, distributed over the whole CPLX2 gene, were found to be highly associated with current cognition of schizophrenic subjects but only marginally with premorbid intelligence. Correspondingly, in Cplx2 -null mutant mice, prominent cognitive loss of function was obtained only in combination with a minor brain lesion applied during puberty, modeling a clinically relevant environmental risk ("second hit") for schizophrenia. In the human CPLX2 gene, 1 of the identified 6 cognition-relevant single-nucleotide polymorphisms, rs3822674 in the 3' untranslated region, was detected to influence microRNA-498 binding and gene expression. The same marker was associated with differential expression of CPLX2 in peripheral blood mononuclear cells. CONCLUSIONS: The PGAS allows identification of marker-associated clinical/biological traits. Current cognitive performance in schizophrenic patients is modified by CPLX2 variants modulating posttranscriptional gene expression.
