Does comorbid substance use disorder exacerbate borderline personality features? A comparison of borderline personality disorder individuals with vs. without current substance dependence.

There is compelling evidence that comorbid borderline personality disorder (BPD) negatively impact the clinical courses and outcomes of substance use disorders (SUD). Conversely, there is little evidence that concurrent SUD exacerbates the clinical characteristics of BPD. Thus, this study sought to examine whether the presence of current substance dependence among BPD patients would be associated with stronger BPD-relevant personality traits and behavioral characteristics. Female BPD patients without (BOR; n = 37) or with current substance dependence (BSUD; n = 19), and female non-BPD/SUD controls (CON; n = 48) were compared with respect to impulsivity, affective lability, affective intensity, externalizing behaviors, and self-harming/suicidal tendencies, taking into consideration their comorbid mood disorders, anxiety disorders, and antisocial personality disorder. Results indicated that both BOR and BSUD groups scored higher than CON in most of the measures, but BOR and BSUD failed to reveal significant group differences especially when the influence of comorbid psychopathology was removed. The overall pattern of findings remained identical even when comparing BPD patients with versus without the diagnosis of lifetime substance dependence. Our results do not support the notion that BPD individuals with SUD display more severe BPD features than individuals with BPD alone.

Reliability and validity of depressive personality disorder

OBJECTIVE: Depressive personality disorder was introduced into DSM-IV's appendix amid controversy. While that disorder appears to be a reliable and valid one, the authors offer new data about its relationship to major depression, dysthymic disorder, and other personality disorders. METHOD: The authors assessed 54 subjects with early-onset, long-standing mild depressive features for depressive personality disorder, axis I and axis II disorders, family history, and treatment history; they conducted follow-up interviews 1 year after the baseline assessment. Subjects with (N=30) and without (N=24) depressive personality disorder were characterized and compared in terms of those variables. RESULTS: Although depressive personality disorder and dysthymia co-occurred in some subjects, 63% of subjects with depressive personality disorder did not have dysthymia, and 60% did not have current major depression. Although subjects with depressive personality disorder were more likely than the mood disorder comparison group to have another personality disorder, 40% had no such disorder. Contrary to study hypotheses, mood disorder was not more common in first-degree relatives of subjects with depressive personality disorder than in relatives of the comparison group. Subjects with and without depressive personality disorder had similar rates of past treatment with medication and psychotherapy; however, the duration of psychotherapy was significantly longer for subjects with than for those without depressive personality. The depressive personality diagnosis was relatively stable over the 1-year follow-up period. CONCLUSIONS: Depressive personality disorder appears to be a relatively stable condition with incomplete overlap with axis I mood disorders and personality disorders. Further studies are needed to better characterize its treatment response and relationship to axis I mood disorders.     

Safety and tolerability of intravenous cibenzoline for acute termination of spontaneous sustained ventricular tachycardia. Cibenzoline and spontaneous VT

OBJECTIVE: To examine the rate of persistence of borderline personality disorder (BPD), the existence of concomitant personality disorders on follow-up, and the predictors of outcome in patients who met criteria for BPD compared with patients with borderline features who failed to meet all of the criteria. METHOD: This prospective cohort study reassessed subjects for BPD diagnosis and cooccurring personality pathology at 7 years follow-up. Initial measures of borderline and comorbid personality psychopathology were used to predict levels of borderline or other personality disorder psychopathology at follow-up. RESULTS: Of the 57 subjects who initially met the criteria for BPD, 30 (52.6%) were found to have remitted BPD, and 27 (47.4%) were characterized as having persistent BPD. The remitted group met significantly fewer comorbid personality disorder diagnoses than the persistent group (mean = 0.8, mean = 3.5 respectively; P < 0.05). Results also indicated that the initial level of borderline psychopathology was predictive of borderline psychopathology at follow-up, which explained 17% of the variance. CONCLUSIONS: This prospective follow-up study found that almost 50% of former inpatients with BPD continue to test positive for BPD at 7 years follow-up, and these persistent BPD patients also had significantly more comorbid personality psychopathology. Borderline psychopathology at follow-up was primarily predicted by the level of borderline psychopathology recorded at the initial assessment.     

The stability of personality traits in individuals with borderline personality disorder.

Although stability and pervasive inflexibility are general criteria for Diagnostic and Statistical Manual of Mental Disorders, 4th edition (American Psychiatric Association, 1994) personality disorders (PDs), borderline PD (BPD) is characterized by instability in several domains, including interpersonal behavior, affect, and identity. The authors hypothesized that such inconsistencies notable in BPD may relate to instability at the level of the basic personality traits that are associated with this disorder. Five types of personality trait stability across 4 assessments over 6 years were compared for BPD patients (N = 130 at first interval) and patients with other PDs (N = 302). Structural stability did not differ across groups. Differential stability tended to be lower for 5-factor model (FFM) traits in the BPD group, with the strongest and most consistent effects observed for Neuroticism and Conscientiousness. Growth curve models suggested that these 2 traits also showed greater mean-level change, with Neuroticism declining faster and Conscientiousness increasing faster, in the BPD group. The BPD group was further characterized by greater individual-level instability for Neuroticism and Conscientiousness in these models. Finally, the BPD group was less stable in terms of the ipsative configuration of FFM facet-level profiles than was the other PD group over time. Results point to the importance of personality trait instability in characterizing BPD. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Cognitive aspects of chronic depression.

Previous research on chronic depression has focused on its link with other mood disorders and Axis II personality disorders. However, there are few data examining whether the cognitive perspective applies to this condition. In this cross-sectional study, 42 outpatients with chronic depression were compared with 27 outpatients with nonchronic major depressive disorder and 24 never psychiatrically ill controls on cognitive variables thought to be related to vulnerability to depression (e.g., dysfunctional attitudes, attributional style, a ruminative response style, and maladaptive core beliefs). Both depressed groups were more elevated than a never-ill comparison group. However, chronically depressed individuals were generally more elevated on measures of cognitive variables than those with major depressive disorders even after controlling for mood state and personality disorder symptoms.

Structural relations between borderline personality disorder features and putative etiological correlates.

This study assessed the structural relations between borderline personality disorder (BPD) features and purported etiological correlates. Approximately 5,000 18-year-old nonclinical young adults were screened for BPD features, and 2 cohorts of participants (total N?=?421; approximately one half of whom endorsed significant borderline features) completed the laboratory phase of the study. Measures included self-report and interview-based assessments of BPD psychopathology, personality, psychopathology in biological parents, and childhood physical and sexual abuse. Significant relations between BPD features and purported etiological correlates of BPD were found. A multivariate model that included parental psychopathology, childhood abuse, and personality factors provided an adequate fit to the data and supported the contention that the personality traits disinhibition and negative affectivity underlie BPD features.

Affective instability: Measuring a core feature of borderline personality disorder with ecological momentary assessment.

Ecological momentary assessment (EMA; Stone & Shiffman, 1994) was used to characterize and quantify a dynamic process--affective instability in borderline personality disorder (BPD). Sixty outpatients (34 with BPD and affective instability; 26 with current depressive disorder but not with BPD or affective instability) carried electronic diaries for approximately 1 month and were randomly prompted to rate their mood state up to 6 times a day. Results indicated that BPD patients (a) did not report significantly different mean levels of positive or negative affect; (b) displayed significantly more variability over time in their positive and negative affect scores; (c) demonstrated significantly more instability on successive scores (i.e., large changes) for hostility, fear, and sadness than did patients with depressive disorders; and (d) were more likely to report extreme changes across successive occasions (≥90th percentile of change scores across participants) for hostility scores. Results illustrate different analytic approaches to quantifying variability and instability of affect based on intensive longitudinal data. Further, results suggest the promise of electronic diaries for collecting data from individuals in their natural environment for purposes of clinical research and assessment.

Borderline personality disorder and personality traits: A comparison of SCID-II BPD and NEO-PI.

62 hospitalized female patients (aged 18–43 yrs) with a clinical diagnosis of borderline personality disorder (BPD) were assessed for Axis II disorders by the SCID-II and for personality traits with the NEO-Personality Inventory (NEO-PI). The predominant personality trait profile for these patients involved a very high Neuroticism score and low Agreeableness score. Five of the 8 BPD criteria had significant correlations with NEO-PI scales. The combination of BPD severity and personality traits as measured on the NEO-PI had a significant relationship to the patients' social adjustment. The utility of gathering information on both borderline personality pathology and personality traits is discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Disentangling emotion processes in borderline personality disorder: Physiological and self-reported assessment of biological vulnerability, baseline intensity, and reactivity to emotionally evocative stimuli.

This study investigated M. Linehan’s (1993) theory that individuals meeting criteria for borderline personality disorder (BPD) have high biological vulnerability to emotion dysregulation, including high baseline emotional intensity and high reactivity to emotionally evocative stimuli. Twenty individuals with BPD, 20 age-matched individuals with generalized social anxiety disorder (SAD), and 20 age-matched normal controls (NCs) participated in 2 separate emotion induction conditions, a standardized condition, and a personally relevant condition. Respiratory sinus arrhythmia (RSA), skin conductance response (SCR), and self-report measures were collected throughout the experiment. BPD participants displayed heightened biological vulnerability compared with NCs as indicated by reduced basal RSA. BPD participants also exhibited high baseline emotional intensity, characterized by heightened SCR and heightened self-reported negative emotions at baseline. However, the BPD group did not display heightened reactivity, as their physiological and self-reported changes from baseline to the emotion inductions tasks were not greater than the other 2 groups.

Mental state decoding abilities in young adults with borderline personality disorder traits.

Previous studies have demonstrated that patients with borderline personality disorder (BPD) tend to misattribute malevolence to benign social stimuli, including facial expressions. Yet, facial emotion recognition studies examining those with BPD have yielded mixed results, with some studies showing impaired accuracy and others demonstrating enhanced accuracy in the recognition of emotions or mental states. The current study examined the ability to decode mental states from photographs of just the eye region of faces in a nonclinical sample of young adults who exhibited BPD traits (high BPD) compared with those who did not (low BPD). Group differences in mental state decoding ability depended on the valence of the stimuli. The high-BPD group performed better for negative stimuli compared with the low-BPD group, but did not perform significantly different from the low-BPD group for stimuli of neutral or positive valence. The high-BPD group also demonstrated a response bias for attributing negative mental states to facial stimuli. In addition, findings suggested that the group difference in accuracy for negative stimuli could not be explained by response bias, because the group difference in response bias for negative stimuli did not reach significance. These findings suggest that BPD traits may be associated with enhanced ability to detect negative emotions and a bias for attributing negative emotions to nonnegative social stimuli.

Analysis of affective instability in ecological momentary assessment: Indices using successive difference and group comparison via multilevel modeling.

Temporal instability of affect is a defining characteristic of psychological disorders such as borderline personality disorder (BPD) and mood cycling disorders. Ecological momentary assessment (EMA) enables researchers to directly assess such frequent and extreme fluctuations over time. The authors examined 4 operationalizations of such temporal instability: the within-person variance (WPV), the first-order autocorrelation, the mean square successive difference (MSSD), and the probability of acute change (PAC). It is argued that the MSSD and PAC measures are preferred indices of affective instability because they capture both variability and temporal dependency in a time series. Additionally, the performance of these 2 measures in capturing within- and between-day instability is discussed. To illustrate, the authors present EMA data from a study of negative mood in BPD and major depressive disorder patients. In this study, MSSD and PAC captured affective instability better than did WPV. Given that MSSD and PAC are individual difference measures, the authors propose that group differences on these indices be explored using generalized multilevel models. Versions of MSSD and PAC that adjust for randomly elapsed time interval between assessments are also presented. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Personality traits in social phobia, II: Changes during drug treatment

BACKGROUND: Patients with social phobia often describe personality traits characterized by avoidant social behavior and more general depressive-anxious features. There is only sparse knowledge about the effects of drug treatment on these traits. METHOD: Fifty-seven patients with social phobia completed a 12-week double-blind, placebo-controlled trial with the reversible and selective monoamine oxidase A inhibitor brofaromine 150 mg/day. The Clinical Global Impressions-Improvement scale, Liebowitz Social Anxiety Scale, a questionnaire with 140 items regarding personality traits, and ratings on the presence or absence of diagnostic criteria for the DSM-III-R avoidant and dependent personality disorders were used for assessments at baseline and endpoint. Comparisons were made with a group of 58 healthy controls. RESULTS: Before treatment, there were no significant differences between the brofaromine and placebo groups in their ratings on situationally bound social anxiety or on personality traits that differed significantly from those of the controls. At endpoint, a marked normalization was noted in the brofaromine group. The changes that had occurred differed significantly from those in the placebo group. The normalization of traits seemed more marked than the normalization of anxiety in more specific social phobic situations. The number of brofaromine patients who fulfilled the criteria for avoidant personality disorder had diminished from 15 (60%) to 5 (20%). CONCLUSION: The results support the conclusion that the maladaptive personality traits characteristic of social phobia are at least as responsive to the monoamine oxidase inhibitor brofaromine as are the more circumscribed social anxiety responses.     

The rejection–rage contingency in borderline personality disorder.

Though long-standing clinical observation reflected in the Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.) suggests that the rage characteristic of borderline personality disorder (BPD) often appears in response to perceived rejection, the role of perceived rejection in triggering rage in BPD has never been empirically tested. Extending basic personality research on rejection sensitivity to a clinical sample, a priming–pronunciation experiment and a 21-day experience-sampling diary examined the contingent relationship between perceived rejection and rage in participants diagnosed with BPD compared with healthy controls. Despite the differences in these 2 assessment methods, the indices of rejection-contingent rage that they both produced were elevated in the BPD group and were strongly interrelated. They provide corroborating evidence that reactions to perceived rejection significantly explain the rage seen in BPD. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Exposure to different spectra of light, continuous light and treatment with melatonin affect reproduction in the Indian desert gerbil Meriones hurrianae (Jerdon)

The present article aims to examine premorbid personality traits of psychiatric patients with various diagnoses by asking their close relatives to retrospectively rate the patients' usual self with a questionnaire designed for the five-factor model of personality, a rapidly emerging comprehensive theory of personality structure. Data for 140 patients and 84 controls were analyzed. Although psychiatric patients as a group were characterized by high neuroticism and low conscientiousness when compared with the healthy controls, there were only a few traits that distinguished a particular diagnostic group from either the normal control or from the rest of the patients: neurotic disorder patients had higher neuroticism scores than the normal controls; unipolar depressives had a higher conscientiousness score than the rest of the patient group. No salient premorbid trait was noted for patients with organic mental disorders, schizophrenic disorders or bipolar disorders.     

Affect and alcohol use: An ecological momentary assessment study of outpatients with borderline personality disorder.

Alcohol use may be viewed as an attempt (albeit maladaptive) to regulate negative emotional states. We examined associations between both negative and positive affects and alcohol use in outpatient women diagnosed with borderline personality disorder (BPD; n = 74), a prototype of emotional dysregulation, as well as a psychiatric control group of women with current depressive disorder (major depressive disorder/dysthymic disorder [MDD\DYS]; n = 50). Participants completed randomly prompted reports of mood and alcohol use up to six times a day over a 28-day period using electronic diaries. Mean levels of either positive or negative affects did not distinguish between drinkers and nondrinkers in either diagnostic group. However, levels of both negative and positive affects were positively associated with alcohol use at the momentary level in BPD drinkers. More robust findings were obtained with respect to within-person affective variability, which was related to alcohol use in multiple ways. BPD drinkers showed higher within-person variability for most negative affects than BPD nondrinkers; MDD\DYS drinkers in general showed less within-person variability than MDD\DYS nondrinkers for negative affects. Multilevel lagged analyses for BPD drinkers indicated that alcohol use was positively related to variability in all affects, concurrently, but fewer significant effects of affect variability on the next day's drinking or significant effects of alcohol use on the next day's affect variability were observed. Among MDD\DYS drinkers, we observed more significant associations between affect variability on next day's alcohol use and of alcohol use on next day's affect variability. We discuss theoretical and methodological issues relevant to these findings as well as implications for future research. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Borderline personality traits and disorder: Predicting prospective patient functioning.

Objective: Decisions about the composition of personality assessment in the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM–V) will be heavily influenced by the clinical utility of candidate constructs. In this study, we addressed 1 aspect of clinical utility by testing the incremental validity of 5-factor model (FFM) personality traits and borderline personality disorder (BPD) symptoms for predicting prospective patient functioning. Method: FFM personality traits and BPD features were correlated with one another and predicted 2-, 4-, 6-, 8-, and 10-year psychosocial functioning scores for 362 patients with personality disorders. Results: Traits and symptom domains related significantly and pervasively to one another and to prospective functioning. FFM extraversion and agreeableness tended to be most incrementally predictive of psychosocial functioning across all intervals; cognitive and impulse action features of BPD features incremented FFM traits in some models. Conclusions: These data suggest that BPD symptoms and personality traits are important long-term indicators of clinical functioning that both overlap with and increment one another in clinical predictions. Results support the integration of personality traits and disorders in DSM–V. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Parenteral clomipramine challenge in depressed adolescents: mood and neuroendocrine response

BACKGROUND: Major depressive disorder (MDD) in the adolescent demonstrates a unique clinical profile, and pathogenic serotonergic dysregulation is hypothesized. Parenteral clomipramine (CMI) is known to distinguish adult MDD from control, but neurochallenge data are lacking in adolescent MDD. METHODS: Thirteen drug-free outpatient adolescents who met DSM-III-R criteria for MDD were compared to adolescent controls by acute neuroendocrine and mood response to 12.5 mg of parenteral CMI. RESULTS: Repeated measures analysis revealed significant changes from baseline for sadness (p < .01) between groups, with normal controls increasing sadness rating after CMI. Prolactin (PRL) maximum change score from baseline was decreased in MDD relative to controls (p < .05). Gender effects on PRL were evident in controls but not in MDD. CONCLUSIONS: The findings of PRL blunting in adolescent MDD mirrors previous work in adults. A unique finding is the induction of sadness in normal adolescent controls after CMI infusion.     

Five-factor trait instability in borderline relative to other personality disorders.

Borderline personality disorder (BPD) is related to five-factor model (FFM) traits and can be characterized as involving psychological and behavioral instability. A previous study comparing the FFM trait stability across individuals with borderline and other personality disorders found that the BPD group tended to have lower stability, particularly on neuroticism and conscientiousness and the overall configuration of FFM profiles over 6 years, suggesting that associated psychological and behavioral variability may be due to trait variability. The current study was designed to test the degree to which these findings replicate in another sample using different diagnostic and trait measures and extending the measurement period to 10 years. Results are consistent with previous findings in showing lower differential (rank-order) stability on conscientiousness, greater mean-level decreases on neuroticism, lower individual-level stability on conscientiousness, and lower ipsative stability of trait profile configurations among those with BPD. However, unlike the previous study, no differences were observed for differential or individual-level neuroticism or mean-level conscientiousness. Overall, findings show that the instability characteristic of BPD extends into typically stable personality traits, and that it does so with some specificity in terms of which traits are affected and how instability manifests.

Relationship between hypomania and personality disorders before and after successful treatment

OBJECTIVE: To examine the effect of hypomanic states on maladaptive personality traits and personality disorders, the authors evaluated personality traits and disorders of patients during an episode of hypomania and after successful somatic treatment. METHOD: The authors used the Structured Interview for DSM-III Personality Disorders to study 66 outpatients who had a lifetime diagnosis of bipolar disorder and who met the minimum Research Diagnostic Criteria for hypomania. All patients had a knowledgeable informant separately undergo the Structured Interview for DSM-III Personality Disorders during the patient's hypomanic state. Outpatients who successfully recovered from the hypomanic episode (N = 47) and their informants were read-ministered the interview 4-8 weeks after the initial assessment. RESULTS: During the hypomanic state, informants generally reported higher levels of maladaptive personality traits among patients than patients themselves. For the patients who recovered successfully from the hypomanic episode, a reduction in all maladaptive personality traits except schizoid and dependent traits was reported by both patients and their informants; however, the decrease reported by patients generally was much greater than that reported by informants. In addition, schizoid traits actually increased after successful treatment according to patient reports but were unchanged according to informant reports. CONCLUSIONS: Hypomania may be associated with an exacerbation of maladaptive personality traits, which may be attenuated after successful treatment. Even with the attainment of euthymic mood, however, about 50% of the cohort had at least one personality disorder, which suggests that a high degree of comorbidity may exist between bipolar disorders and maladaptive personality traits or personality disorders.     

Intrinsic motivation in schizophrenia: Relationships to cognitive function, depression, anxiety, and personality.

The goal of the current project was to assess subjective reports of intrinsic motivation and their relationship to cognitive function, mood, and personality in schizophrenia. The authors used the Motivational Trait Questionnaire to examine 3 components of intrinsic motivation (personal mastery, competitive excellence, motivation related to anxiety). They also examined fluid intelligence, context processing, and working memory, as well as self-reports of mood and personal traits related to motivation. Participants were 66 individuals with schizophrenia or schizoaffective disorder and 44 healthy controls. Self-reports of personal mastery and competitive excellence did not differ between controls and individuals with schizophrenia, though patients did report significantly higher motivation related to anxiety. Among controls, but not patients, self-reports of intrinsic motivation were strongly related to cognitive performance. In contrast, both controls and patients showed similar strong relationships between self-reports of intrinsic motivation and related measures of mood and personality. These results are not consistent with the hypothesis that motivational deficits in schizophrenia reflect impairments in intrinsic motivation. However, they do suggest that the normal relationship between self-reports of intrinsic motivation and cognitive function is disrupted in schizophrenia.
