Substance use disorders among personality disordered patients admitted for day hospital treatment. Implications for service developments

Comorbidity Profiles of Psychotic Patients in Emergency Psychiatry

Objectives: Individuals with psychotic symptoms presenting to emergency psychiatry often have comorbid symptoms, such as substance misuse, depression, and anxiety. Many will also have symptoms linked to previous traumatic experiences such as impulsivity, often found in comorbid personality disorders. Although various studies have looked at specific comorbid symptoms, little is known regarding how these symptoms co-exist in individuals with psychotic symptoms and their link with social functioning. The primary objective of the present study was to identify comorbidity profiles among individuals seeking emergency room services for psychotic symptoms. The secondary objective was to investigate the relationship between comorbid symptoms and social functioning deficits in this same population. Methods: Data from 546 individuals seeking psychiatric help for psychotic symptoms was collected within the Signature Project (large data bank) in a psychiatric emergency. Participants answered brief measures of symptoms of alcohol/substance misuse (AUDIT, DAST), depression (PHQ-9), anxiety (STAI-6), childhood trauma (CEVQ), impulsivity (UPPS) and social functioning deficits (WHODAS). For this study, symptom measures and social functioning at baseline were used. Results: Cluster analyses conducted using three different methods revealed a consensus of five classes of comorbid presentations. Class 1 (n = 90) grouped people who had a high score for childhood trauma, with fairly high scores for anxiety and depression. Class 2 (n = 176) included people with mostly psychotic symptoms with little comorbid presentation across other measures. Class 3 (n = 81) grouped people with the highest anxiety and depression scores as well as high drug use and impulsivity. Individuals in Class 4 (n = 87) had the highest scores on alcohol and substance abuse, as well as high impulsivity. Class 5 (n = 112) grouped people with very low anxiety and depression scores but average trauma, alcohol, and substance misuse scores. Linear regressions revealed an association between social functioning, and depression, anxiety, and childhood trauma. Conclusions: Comorbid presentations of individuals with psychosis are frequent and diverse. Depression and anxiety, in particular, worsen social functioning deficits in people with psychotic symptoms. Given their impact on functioning, psychiatric treatments should address these comorbidities during hospitalization, as well as when followed in the community.

Personality disorders: patient characteristics and level of outpatient treatment service

BACKGROUND

In this naturalistic study, patients with personality disorders (N = 388) treated at Stolpegaard Psychotherapy Center, Mental Health Services, Capital Region of Denmark were allocated to two different kinds of treatment: a standardized treatment package with a preset number of treatment hours (basic hospital service) and 2: a specialized treatment program for the most severely affected patients without a predetermined restricted number of treatment hours and significantly more individual psychotherapy (regional specialized hospital services).

AIMS

To investigate patient characteristics associated with clinicians' allocation of patients to the two different personality disorder services.

METHODS

Patient characteristics across eight domains were collected in order to study whether there were systematic differences between patients allocated to the two different treatments. Patient characteristics included measures of symptom severity, personality pathology, trauma and socio-demographic characteristics. Significance testing and binary regression analysis were applied to identify important predictors.

RESULTS

Patient characteristics on fifteen variables differed significantly, all in the expected direction, with patients in regional specialized hospital services showing more pathology and psychosocial problems. In the regression model, only age and two variables capturing psychosocial functioning remained significant predictors of allocation.

DISCUSSION

The finding that younger age was the most significant predictor of longer treatment replicates an earlier finding of allocation to treatment for personality disorder. Overall, this study therefore lends further support to the importance of demographic and social contextual factors in clinicians' allocation of patients to different treatment services for personality disorder.

Comparison of treatment outcomes in severe personality disorder patients with or without substance use disorders: a 36-month prospective pragmatic follow-up study

BACKGROUND

Concurrent personality disorder (PD) and substance use disorder (SUD) are common in clinical practice. However, SUD is the main criterion for study exclusion in most psychotherapeutic studies of PD. As a result, data on treatment outcomes in patients with concurrent PD/SUD are scarce.

METHODS

The study sample consisted of 51 patients diagnosed with severe PD and admitted for psychotherapeutic treatment as a part of routine mental health care. All patients were diagnosed with PD according to the Structured Clinical Interview for PD. Patients were further assessed (DSM-IV diagnostic criteria) to check for the presence of concurrent SUD, with 28 patients diagnosed with both disorders (PD-SUD). These 28 cases were then compared to the 23 patients without SUD (PD-nSUD) in terms of psychiatric hospitalizations and psychiatric emergency room (ER) visits before and during the 6-month therapeutic intervention and every 6 months thereafter for a total of 36 months.

RESULTS

The baseline clinical characteristics correspond to a sample of PD patients (78% met DSM-IV criteria for borderline PD) with poor general functioning and a high prevalence of suicide attempts and self-harm behaviors. Altogether, the five outcome variables - the proportion and the number of psychiatric inpatient admissions, the number of days hospitalized, and the proportion and the number of psychiatric ER visits - improved significantly during the treatment period, and this improvement was maintained throughout the follow-up period. Although PD-SUD patients had more psychiatric hospitalizations and ER visits than PD-nSUD patients during follow-up, the differences between these two groups remained stable over the study period indicating that the treatment was equally effective in both groups.

CONCLUSION

Specialized psychotherapy for severe PD can be effectively applied in patients with concurrent PD-SUD under usual practice conditions. These findings suggest that exclusion of patients with dual disorders from specialized treatments is unjustified.

Borderline personality traits and substance use: genetic factors underlie the association with smoking and ever use of cannabis, but not with high alcohol consumption

Borderline personality disorder (BPD) and substance use disorders often co-occur. Both disorders are heritable and family studies showed that there are familial factors that increase the risk for BPD as well as substance use/abuse. This is the first study that investigates whether the association of borderline personality traits (BPT) with substance use reflects an underlying genetic vulnerability or nongenetic familial influences. To this end we analyzed data of 5,638 Dutch and Belgian twins aged between 21-50 years from 3,567 families. Significant associations between BPT and high alcohol consumption (r = .192), regular smoking (r = .299), and ever use of cannabis (r = .254) were found. Bivariate genetic analyses showed that the associations of BPT and substance use had different etiologies. For regular smoking and for ever use of cannabis, the correlation with BPT was explained by common genetic factors. Interestingly, for high alcohol consumption and BPT the association was explained by unique environmental factors that influence both traits rather than common genetic factors.

Borderline personality symptoms in short-term and long-term abstinent alcohol dependence

BACKGROUND

Comorbidity of borderline personality disorder (BPD) and substance and alcohol use disorders (SUDs and AUDs) is very high. The literature suggests a negative synergy between BPD and SUDs, which may impact an individual's ability to achieve and maintain remission of either disorder in the face of the other.

METHODS

We examined lifetime and current (past year) BPD symptom counts in 3 gender- and age-comparable groups: short-term abstinent alcoholics (STA, 6 to 15 weeks abstinent), long-term abstinent alcoholics (LTA, more than 18 months abstinent), and nonsubstance-abusing controls (NSAC). Abstinent individuals were recruited primarily from mutual-help recovery networks and about half had comorbid drug dependence. BPD symptoms were obtained using the Structured Clinical Interview for DSM-IV-TR Axis II Personality Disorders, followed up with questions regarding currency, but did not require that BPD symptoms represent persistent or pervasive behavior such as would meet criteria for BPD diagnosis. Thus, our study dealt only with BPD symptoms, not BPD diagnoses.

RESULTS

Alcoholics had more lifetime and current symptoms for most all BPD criteria than NSAC. In general, STA and LTA did not differ in BPD symptoms, except for a group-by-gender effect for both lifetime and current anger-associated symptoms and for lifetime abandonment avoidance symptoms. For these cases, there were much higher symptom counts for STA women versus men, with comparable symptom counts for LTA women versus men.

CONCLUSIONS

Our results suggest for the most part that BPD symptoms do not prevent the maintenance of recovery in AUD and SUD individuals who have established at least 6 weeks abstinence within the mutual-help recovery network-in fact the presence of BPD symptoms is the norm. However, we did find difficulty in establishing longer-term abstinence in women with anger-associated symptoms and abandonment avoidance symptoms.

A longitudinal study of risk factors for incident drug use in adults: findings from a representative sample of the US population

OBJECTIVE

To examine baseline mental disorders and other correlates among people who have not previously used drugs as potential risk factors for incident drug use at 3-years' follow-up.

METHOD

Data came from the National Epidemiologic Survey on Alcohol and Related Conditions (commonly referred to as the NESARC) Wave 2 (2004 to 2005; n = 34 653), a longitudinal nationally representative survey of mental illness in community-dwelling adults. The study group consisted of people who reported no history of any illicit drug use or prescription drug misuse at Wave 1 (2001 to 2002). Logistic regression analyses were used to compare people with first-episode drug use at Wave 2 (n = 1145) to those who remained abstinent (n = 25 790) across various Wave 1 correlates, including sociodemographic factors, mental disorders (including alcohol use disorders and nicotine dependence), childhood adversity, and family history of substance use disorders.

RESULTS

All measures of childhood adversity were associated with an increased risk of incident drug use, as were alcohol or drug problems in first-degree relatives. In models adjusted for childhood adversity and a family history of addiction, a pre-existing mood disorder (AOR 1.31; 95% CI 1.04 to 1.64), personality disorder (AOR 1.82; 95% CI 1.50 to 2.20), previous nicotine dependence (AOR 1.41; 95% CI 1.09 to 1.83), and alcohol abuse or dependence (AOR 1.96; 95% CI 1.48 to 2.60) were independently associated with new-onset drug use at follow-up.

CONCLUSIONS

Specific mental disorders independently increase the risk of progression to incident drug use among people who were previously abstinent. Early-life adversities and addiction in family members accounts for some, but not all, of this observed relation.

Exposure to teacher bullying in schools: a study of patients with personality disorders

BACKGROUND

The aim of this study was to examine the level and affect of exposure to teacher bullying in primary and secondary schools on patients with personality disorders (PD).

METHOD

The study group contained 116 people (18-60 years old); 49 patients diagnosed with PD undergoing psychiatric treatment in 10 different psychiatric outpatient clinics in the Southern and Middle part of Norway, and a control group consisting of 67 people who worked in an institution for somatic/elderly people and an institution for people with drug/alcohol dependency in the Middle part of Norway. All study participants filled out a self-report questionnaire, which included demographic data, one item about whether they have been bullied by one or several teachers, and 28 items regarding subjection to negative acts from teachers based on the Negative Acts Questionnaire -Revised (NAQ-R).

RESULTS

Patients diagnosed with PD reported significantly more bullying by teachers in both primary school (OR 7.3; 95% CI 1.9-27.7) and secondary school (OR 5.8; 95% CI 1.1-30.5) than healthy controls. Patients with PD also reported a higher prevalence of negative acts from teachers than healthy controls in both primary and secondary schools, such as differential treatment, ridicule, humiliation, and being ignored or neglected at least once weekly.

CONCLUSION

Our findings indicate a correlation between bullying from teachers, as reported by PD patients, and the development of PD in adulthood. The problem of teacher bullying deserves more attention with regard to this possible correlation between student victimization and the development of PD.
