Bullying in clinical high risk for psychosis participants from the NAPLS-3 cohort

Purpose

Bullying is associated with a heightened risk for poor outcomes, including psychosis. This study aimed to replicate previous findings on bullying prevalence in clinical high-risk (CHR) individuals, to assess the longitudinal course of clinical and functional variables between bullied and non-bullied CHR and the association of bullying with premorbid functioning, clinical outcome, transition to psychosis and risk of violence.

Methods

The sample consisted of 691 CHR participants and 96 healthy controls. Participants reported whether they had experienced bullying and how long it had lasted. Assessments included DSM-5 diagnoses, attenuated psychotic symptoms, negative symptoms, social and role functioning, depression, stress, premorbid functioning, and risk of violence. The bullied and non-bullied CHR groups were compared at baseline and further longitudinally on clinical and functioning variables and transition to psychosis.

Results

Bullying was more prevalent among CHR individuals than healthy controls. Bullied CHR had a higher prevalence of PTSD and more severe depression and stress at baseline than non-bullied CHR. There was no impact of bullying on clinical and functional variables over time. Bullying was not related to final clinical status or transition to psychosis. However, bullied participants had poorer premorbid functioning and a greater risk of violence.

Conclusion

While bullying may not impact the likelihood of CHR individuals to transition to psychosis, it may be a risk factor for development of the at-risk state and may be related to a greater risk of violence. Future studies should consider bullying perpetration among CHR individuals.

     

Neurobiological correlates of borderline personality disorder

Although patients with borderline personality disorder (BPD) are commonly seen in psychiatric practice, there has been far less biological research in BPD than in other psychiatric disorders. This article reviews the neurobiological research that has been performed to date in BPD and integrates the biological, psychological, and clinical findings in this disorder. BPD is best thought of in terms of dimensions rather than as a specific disorder. Each dimension has a biological profile and may be expressed differently in different patients. Four core elements are suggested to play a major role in the development of BPD: interpersonal stress, affective instability, impulsivity, and dissociation and self-injurious behavior. Genetic and environmental factors lead to brain alterations that are the basis for specific presentations of the disorder, such as self-injurious and impulsive aggressive behavior.     

MRI and PET study of deficits in hippocampal structure and function in women with childhood sexual abuse and posttraumatic stress disorder

OBJECTIVE: Animal studies have suggested that early stress is associated with alterations in the hippocampus, a brain area that plays a critical role in learning and memory. The purpose of this study was to measure both hippocampal structure and function in women with and without early childhood sexual abuse and the diagnosis of posttraumatic stress disorder (PTSD). METHOD: Thirty-three women participated in this study, including women with early childhood sexual abuse and PTSD (N=10), women with abuse without PTSD (N=12), and women without abuse or PTSD (N=11). Hippocampal volume was measured with magnetic resonance imaging in all subjects, and hippocampal function during the performance of hippocampal-based verbal declarative memory tasks was measured by using positron emission tomography in abused women with and without PTSD. RESULTS: A failure of hippocampal activation and 16% smaller volume of the hippocampus were seen in women with abuse and PTSD compared to women with abuse without PTSD. Women with abuse and PTSD had a 19% smaller hippocampal volume relative to women without abuse or PTSD. CONCLUSIONS: These results are consistent with deficits in hippocampal function and structure in abuse-related PTSD.     

Traumatic exposure and posttraumatic stress disorder in borderline,schizotypal, avoidant,and obsessive-compulsive personality disorders: findings from the collaborative longitudinal personality disorders study

The association between trauma and personality disorders (PDs), while receiving much attention and debate, has not been comprehensively examined for multiple types of trauma and PDs. The authors examined data from a multisite study of four PD groups: schizotypal, borderline (BPD), avoidant, and obsessive-compulsive, and a major depression comparison group. Rates of traumatic exposure to specific types of trauma, age of first trauma onset, and rates of posttraumatic stress disorder are compared. Results indicate that BPD participants reported the highest rate of traumatic exposure (particularly to sexual traumas, including childhood sexual abuse), the highest rate of posttraumatic stress disorder, and youngest age of first traumatic event. Those with the more severe PDs (schizotypal, BPD) reported more types of traumatic exposure and higher rates of being physically attacked (childhood and adult) when compared to other groups. These results suggest a specific relationship between BPD and sexual trauma (childhood and adult) that does not exist among other PDs. In addition, they support an association between severity of PD and severity of traumatic exposure, as indicated by earlier trauma onset, trauma of an assaultive and personal nature, and more types of traumatic events.     

Short-term diagnostic stability of schizotypal,borderline, avoidant,and obsessive-compulsive personality disorders

OBJECTIVE: Personality disorders are defined as enduring patterns of maladaptive behaviors and traits that are stable over time. This study prospectively examined the stability of four personality disorders (schizotypal, borderline, avoidant, and obsessive-compulsive) over a 1-year follow-up period. METHOD: Subjects (N=668) were recruited from multiple clinical settings at four collaborating institutions. Subjects met criteria for one or more of the four personality disorders or were part of a comparison group of subjects with major depressive disorder and no personality disorder. Diagnoses were established by using semistructured interviews. Follow-up assessments, conducted 6 and 12 months after the baseline assessment, included monthly ratings of all criteria for the four personality disorders and weekly ratings of the course of major depressive disorder. The current report is based on 621 subjects with complete data through 12 months of the follow-up period. RESULTS: Significantly more subjects in each personality disorder group remained at diagnostic threshold throughout the 12 months of the follow-up period than did those in the major depressive disorder group. A continuous measure of number of criteria met was highly correlated across the three assessments. The majority of personality disorder subjects, however, did not consistently remain at diagnostic threshold, and the mean number of criteria met decreased significantly for each group. CONCLUSIONS: Individual differences in personality disorder features appear to be highly stable, although the number of criteria present decreases over time. Personality disorders may be characterized by stable trait constellations that fluctuate in degree of maladaptive expression.     

Diagnostic efficiency of borderline personality disorder criteria in hospitalized adolescents: comparison with hospitalized adults

OBJECTIVE: The authors examined the diagnostic efficiency of borderline personality disorder criteria in adolescent inpatients. For comparison, diagnostic efficiency of borderline personality disorder criteria was also examined in a group of concurrently recruited adult inpatients. METHOD: Adolescents (N=123) and adults (N=106) were reliably assessed with the Personality Disorder Examination, a semistructured diagnostic interview for DSM-III-R personality disorders. Sixty-five adolescents and 50 adults met diagnostic criteria for borderline personality disorder. Conditional probabilities were calculated to determine which borderline personality disorder criteria were most efficient as inclusion criteria and as exclusion criteria. Adolescents and adults were analyzed separately, and the results were compared. RESULTS: There were no significant differences between groups with regard to the base rates of the borderline personality disorder diagnosis nor for any borderline personality disorder criterion. The best inclusion criterion for the adolescents was abandonment fears, though for the adults all symptoms were approximately equivalent in this regard. The most efficient exclusion criterion was uncontrolled anger for the adolescents and impulsiveness for the adults. CONCLUSIONS: In hospitalized patients, borderline personality disorder and its symptoms appear to be as frequent for adolescents as for adults. Despite these surface similarities between groups with respect to symptom patterns, several differences were found at the level of the diagnostic efficiency for individual borderline personality disorder criteria. These differences may shed light on the nature of borderline psychopathology during adolescence.     

Treatment utilization by patients with personality disorders

OBJECTIVE: Utilization of mental health treatment was compared in patients with personality disorders and patients with major depressive disorder without personality disorder. METHOD: Semistructured interviews were used to assess diagnosis and treatment history of 664 patients in four representative personality disorder groups-schizotypal, borderline, avoidant, and obsessive-compulsive-and in a comparison group of patients with major depressive disorder. RESULTS: Patients with personality disorders had more extensive histories of psychiatric outpatient, inpatient, and psychopharmacologic treatment than patients with major depressive disorder. Compared to the depression group, patients with borderline personality disorder were significantly more likely to have received every type of psychosocial treatment except self-help groups, and patients with obsessive-compulsive personality disorder reported greater utilization of individual psychotherapy. Patients with borderline personality disorder were also more likely to have used antianxiety, antidepressant, and mood stabilizer medications, and those with borderline or schizotypal personality disorder had a greater likelihood of having received antipsychotic medications. Patients with borderline personality disorder had received greater amounts of treatment, except for family/couples therapy and self-help, than the depressed patients and patients with other personality disorders. CONCLUSIONS: These results underscore the importance of considering personality disorders in diagnosis and treatment of psychiatric patients. Borderline and schizotypal personality disorder are associated with extensive use of mental health resources, and other, less severe personality disorders may not be addressed sufficiently in treatment planning. More work is needed to determine whether patients with personality disorders are receiving adequate and appropriate mental health treatments.     

Integration and sealing over. Clinically distinct recovery styles from schizophrenia.

Concepts of integration and sealing over are common clinical psychiatric parlance. Our experience studying and treating acute schizophrenic patients, primarily with psychosocial techniques, has emphasized the meaningfulness of these concepts. By studying the recovered patient's attitude toward his psychotic experiences, we have obtained material from which to formulate definitions and these concepts. Integrators tend to be curious about their symptoms, regard them as part of their life's pattern, and gain information from them, resulting in a more flexible and variable attitude toward illness than patients who seal over. The latter have rather fixed, usually negative, views of their illness, and tend not to strive to understand their psychotic symptoms nor to place their psychotic experiences in perspective with their lives before and after psychosis.     

Avoidant personality disorder and social phobia: distinct enough to be separate disorders?

OBJECTIVE: Existing evidence from anxiety disorder research indicates that social phobics (SP) with avoidant personality disorder (AVPD) experience more anxiety and show more impairment than patients with SP alone. The purpose of this study was to examine whether in patients diagnosed with AVPD, the co-occurrence of SP adds to its severity. We hypothesized that the addition of SP will not add to the severity of AVPD alone. METHOD: Two groups of patients (AVPD=224; AVPD/SP=101) were compared at baseline and 2 years later on multiple demographic and clinical variables. RESULTS: Patients with AVPD and an additional diagnosis of SP differed little from patients with AVPD alone. CONCLUSION: These findings suggest that AVPD and SP may be alternative conceptualizations of the same disorder.
