How does dialectical behavior therapy facilitate treatment retention among individuals with comorbid borderline personality disorder and substance use disorders?

Psychotherapies in opioid use disorder: toward a step-care model

Opioid use disorder (OUD) is characterized by a lack of control in opioid use, resulting in psychological distress and deficits in interpersonal and social functioning. OUD is often associated with psychiatric comorbidities that increase the severity of the disorder. The consequences of OUD are dramatic in terms of increased morbi-mortality. Specific medications and psychotherapies are essential tools not only in the treatment of OUD but also in the prevention of suicide and overdoses. In our review, we assess the different types of psychotherapies (counseling, motivational interviewing, contingency management, cognitive-behavioral therapy, and dialectical-behavior therapy) that are delivered to opioid users, either associated or un-associated with OUD medications and/or medications for psychiatric disabilities. We describe the application of these therapies first to adult opioid users and then to adolescents. This work led us to propose a stepped-care model of psychotherapies for OUD which provided information to assist clinicians in decision-making regarding the selection of psychotherapeutic strategies according to patients' OUD severity.

Efficacy of Dialectical Behavioral Therapy for Emotion Dysregulation in Patients with Dual Diagnosis of Borderline Personality Disorder and Substance Use Disorder

Background:

The published evidence supports the efficacy of dialectical behavioral therapy (DBT) to treat patients with borderline personality disorder and particular emphasis on emotion dysregulation as a psychopathological construct.

Aim:

To assess the efficacy of DBT for improving emotion dysregulation among patients with dual diagnosis of borderline personality disorder and substance use disorder.

Methods:

We recruited 40 patients meeting DSM-5 criteria for borderline personality disorder and substance use disorder and assigned them to one of two groups of 20 participants each. One group underwent DBT therapy and the other group followed a treatment-as-usual (TAU) protocol over one year. We used the scores of the difficulties in emotion regulation scale (DERS) at baseline, immediately after therapy, and 4 months after therapy to assess emotion dysregulation.

Results:

We found significant improvements (p<0.05) in the DBT group after therapy that were maintained at least for 4 months afterwards based on the DERS scores (including subscale scores). More patients dropped out of the treatment in the TAU group than in the DBT group.

Conclusion:

DBT is a potentially efficacious psychological intervention to treat emotion dysregulation in patients with borderline personality disorder and substance use disorder.

Predictors of Dropout From a 20-Week Dialectical Behavior Therapy Skills Group for Suicidal Behaviors and Borderline Personality Disorder

Treatment dropout among individuals with borderline personality disorder (BPD) is associated with negative psychosocial outcomes. Identifying predictors of dropout among this population is critical to understanding how to improve treatment retention. The present study extends the current literature by examining both static and dynamic predictors of dropout. Chronically suicidal outpatients diagnosed with BPD (N = 42) were randomly assigned to a 20-week dialectical behavior therapy (DBT) skills training group. Static and dynamic predictors were assessed at baseline, 5, 10, 15, 20 weeks, and 3 months post-intervention. A post-hoc two-stage logistic regression analysis was conducted to predict dropout propensity. Receiving disability benefits at baseline and decreases in mindfulness were associated with significantly increased probability of dropout. Clinicians working with chronically self-harming outpatients diagnosed with BPD would benefit from prioritizing clinical interventions that enhance mindfulness in order to decrease dropout propensity.

An intervention for parents with severe personality difficulties whose children have mental health problems: a feasibility RCT

BACKGROUND

The children of parents with severe personality difficulties have greater risk of significant mental health problems. Existing care is poorly co-ordinated, with limited effectiveness. A specialised parenting intervention may improve child and parenting outcomes, reduce family morbidity and lower the service costs.

OBJECTIVES

To develop a specialised parenting intervention for parents affected by severe personality difficulties who have children with mental health problems and to conduct a feasibility trial.

DESIGN

A pragmatic, mixed-methods design to develop and pilot a specialised parenting intervention, Helping Families Programme-Modified, and to conduct a randomised feasibility trial with process evaluation. Initial cost-effectiveness was assessed using UK NHS/Personal Social Services and societal perspectives, generating quality-adjusted life-years. Researchers collecting quantitative data were masked to participant allocation.

SETTING

Two NHS mental health trusts and concomitant children's social care services.

PARTICIPANTS

Parents who met the following criteria: (1) the primary caregiver of the index child, (2) aged 18-65 years, (3) have severe personality difficulties, (4) proficient in English and (5) capable of providing informed consent. Index children who met the following criteria: (1) aged 3-11 years, (2) living with index parent and (3) have significant emotional/behavioural difficulties. Exclusion criteria were (1) having coexisting psychosis, (2) participating in another parenting intervention, (3) receiving inpatient care, (4) having insufficient language/cognitive abilities, (5) having child developmental disorder, (6) care proceedings and (7) index child not residing with index parent.

INTERVENTION

The Helping Families Programme-Modified - a 16-session intervention using structured, goal-orientated strategies and collaborative therapeutic methods to improve parenting, and child and parent functioning. Usual care - standard care augmented by a single psychoeducational session.

MAIN OUTCOME MEASURES

Trial feasibility - rates of recruitment, eligibility, allocation, retention, data completion and experience. Intervention acceptability - rates of acceptance, completion, alliance (Working Alliance Inventory-Short Revised) and experience. Outcomes - child (assessed via Concerns About My Child, Eyberg Child Behaviour Inventory, Child Behaviour Checklist-Internalising Scale), parenting (assessed via the Arnold-O'Leary Parenting Scale, Kansas Parental Satisfaction Scale), parent (assessed via the Symptom Checklist-27), and health economics (assessed via the Client Service Receipt Inventory, EuroQol-5 Dimensions).

RESULTS

The findings broadly supported trial feasibility using non-diagnostic screening criteria. Parents were mainly referred from one site (75.0%). Site and participant factors delayed recruitment. An estimate of eligible parents was not obtained. Of the 86 parents referred, 60 (69.7%) completed screening and 48 of these (80.0%) were recruited. Participants experienced significant disadvantage and multiple morbidity. The Helping Families Programme-Modified uptake (87.5%) was higher than usual-care uptake (62.5%). Trial retention (66.7%, 95% confidence interval 51.6% to 79.6%) exceeded the a priori rate. Process findings highlighted the impact of random allocation and the negative effects on retention. The Helping Families Programme-Modified was acceptable, with duration of delivery longer than planned, whereas the usual-care condition was less acceptable. At initial follow-up, effects on child and parenting outcomes were detected across both arms, with a potential outcome advantage for the Helping Families Programme-Modified (effect size range 0.0-1.3). For parental quality-adjusted life-years, the Helping Families Programme-Modified dominated usual care, and child quality-adjusted life-years resulted in higher costs and more quality-adjusted life-years. At second follow-up, the Helping Families Programme-Modified was associated with higher costs and more quality-adjusted life-years than usual care. For child quality-adjusted life-years, when controlled for baseline EuroQol-5 Dimensions, three-level version, usual care dominated the Helping Families Programme-Modified. No serious adverse events were reported.

CONCLUSION

The Helping Families Programme-Modified is an acceptable specialised parenting intervention. Trial methods using non-diagnostic criteria were largely supported. For future work, a definitive efficacy trial should consider site selection, recruitment methods, intervention efficiency and revised comparator condition.

Autistic traits in mentalization-based treatment for concurrent borderline personality disorder and substance use disorder: Secondary analyses of a randomized controlled feasibility study

Autism is suggested to be a dimensional construct and often represents a comorbid state. However, research on the clinical implications of the presence of autistic traits is scarce. This study aimed to investigate the impact of subclinical autistic traits in mentalization-based treatment (MBT) for concurrent borderline personality disorder (BPD) and substance use disorder (SUD). Based on the data of a randomized controlled feasibility study by Philips, Wennberg, Konradsson, and Franck (2018), secondary analyses were conducted. It was tested, if patients' (N = 46) levels of autistic traits were associated with treatment outcome measured in the course of and after treatment using interviews and self-report measures. Participants' autistic traits were not associated with the change in the severity of BPD throughout and at the end of the treatment. However, results showed associations between autistic traits and the change in patients' consumption of alcohol in the course of MBT. Furthermore, there was an association between autistic traits and the change in mentalizing capacity at the end of MBT, indicating that elevated autistic traits were associated with an improvement in mentalizing capacity. Autistic traits on a subclinical level do not appear to be a complicating factor in MBT for concurrent BPD and SUD. On the contrary, in terms of mentalizing capacity autistic traits might be associated with a larger potential for improvement or facilitate treatment outcome. Further research is needed to explore the role of higher autistic traits in treatment of this special patient group.

Effectiveness of Dialectical Behavioral Therapy on Executive Function, Emotional Control and Severity of Symptoms in Patients with Bipolar I Disorder

Background:

Bipolar disorder is a disabling illness characterized by recurrent episodes of mania, hypomania, and depression. The dialectical behaviour therapy (DBT) is basically designed to help regulate excitement, tolerance of discomfort, mindfulness and interpersonal relationships. This study aimed to determine the effectiveness of DBT on executive function, emotional control and symptom relief in patients with type 1 bipolar disorder.

Materials and Methods:

This clinical trial was conducted on 50 patients with type 1 bipolar disorder. These patients were divided into two 25 populated groups of controls and intervention. The control group did not receive any other alternative therapy apart from routine medications, but in the intervention group, in addition to routine medications, DBT treatment was also done as complementary therapy in 12 sessions based on Dick's protocol. Then, Mania severity, emotional control and their executive functions were evaluated before and after the intervention and compared in two groups.

Results:

After the intervention, the scores of mania and depression mood with the mean of 2.12 ± 3.09 and 31.08 ± 8.98 respectively in intervention group were significantly lower than control group with the mean of 4.24 ± 4.11 and 39.92 ± 9.05 respectively (P < 0.05). Depression and executive function of the patients had no significant difference between the two groups in the post-intervention period and had a modest and non-significant change.

Conclusion:

DBT has been effective in decreasing the intensity of mania, but, it cannot be used to reduce the emotional instability and impulsivity of these patients along with drug therapy although it has improved the executive functions and depression of the patients.

Mentalization-Based Treatment From the Patients' Perspective - What Ingredients Do They Emphasize?

Objective: The aim of this study was to explore how patients with personality disorder (PD) and substance use disorder (SUD) experience mentalization-based treatment (MBT), in particular what they consider useful and less useful elements of the therapy.

Method: Semi-structured qualitative interviews with 13 participants were conducted. Participants were interviewed on their experience of the different elements of MBT, their experience of working in the transference, and their view on MBT as a whole. Thematic analyses were performed within a hermeneutical-phenomenological epistemology, with an emphasis on researcher reflexivity.

Results: The following themes were found in the material: “I am not alone,” “Taking blinders off,” “Just say it,” “The paradox of trust,” and “Follow me closely.” Three of these themes concerned therapist interventions; these involved addressing the relationship with the patients, addressing negative or unspoken feelings in the sessions, and validating and tolerating patients’ affect. Two themes concerned group therapy experiences; these were the experience of sameness with co-patients in group and the experience of discovering different perspectives in group.

Conclusions: Patients’ experiences of useful elements in MBT resonate with theoretical tenets of (borderline) personality pathology, in particular attachment disturbances and emotional dysregulation. Patients highlight what we would label working in the therapeutic relationship, addressing transferential and counter-transferential processes explicitly, emotional validation, and enhancing mentalizing in its own right.

An evaluation of predictors of dropout from an Emotional Coping Skills programme in a community mental health service

Drop-out from mental health services is a significant problem, leading to inefficient use of resources and poorer outcomes for clients. Adapted dialectical behaviour therapy (DBT), often termed Emotional Coping Skills (ECS) programmes, show some of the highest rates of drop-out from therapy recorded in the literature. The present study aimed to add to the evidence base, by evaluating predictors of drop-out from an ECS programme in a UK-based Community Mental Health Team (CMHT). An existing data set of 49 clients, consisting of clients’ responses on a number of questionnaires, was evaluated for predictors of drop-out. Predictors of drop-out included symptom severity, substance use and client demographics. Independent-samples t-tests and chi-square cross tabs analyses revealed no significant differences between drop-outs and completers of therapy on any of the variables. This suggests that contrary to common assumptions and previous findings, clients using substances, who are highly anxious, or who experience a greater degree of emotion dysregulation, are not more likely to drop out from ECS programmes compared with other individuals. The clinical implications of these findings and future research are discussed within the wider context of the evidence base.

Dialectical Behavior Therapy Skills Training in Alcohol Dependence Treatment: Findings Based on an Open Trial

BACKGROUND

Dialectical behavior therapy (DBT) has demonstrated efficacy in treating disorders such as alcohol dependence that are characterized by emotional dysregulation. Preliminary evidence has revealed the feasibility of DBT skills training (ST) as a stand-alone treatment for such disorders. Although emotional dysregulation plays a significant role in alcohol dependence, there are no previous reports of using DBT-ST to treat it.

OBJECTIVES

The aim of this study was to evaluate the duration of abstinence and changes in emotional regulation in a 3-month DBT-ST program for alcohol-dependent patients and to look for relations between abstinence and emotional regulation.

METHODS

We administered the Difficulties in Emotion Regulation Scale (DERS) and used urine toxicology screening to monitor alcohol/substance intake among the 244 subjects admitted to the program.

RESULTS

Among the 157 patients who completed the treatment, 73.2% were abstinent at the end of the program, and their emotional regulation improved. Improvement was independent of the initial severity of both alcohol use and emotional dysregulation. For substance use outcomes, we found a partial mediation role of improved emotional regulation.

CONCLUSIONS

This is the first open trial to show improved alcohol-related behavior and emotional regulation in alcohol-dependent patients treated with DBT-ST and to posit a partial but significant relation between improved emotional regulation and alcohol use outcomes. In the treatment of alcohol dependence, emotional regulation may be a relevant factor for therapists to consider.

A Within-Person Analysis of the Association between Borderline Personality Disorder and Alcohol Use in Adolescents

Many studies examining the association between borderline personality disorder (BPD) and alcohol use during adolescence have focused on between-individual differences (rank order stability), comparing whether adolescents with elevated rates of alcohol use have higher BPD symptoms than those with lower rates of alcohol use. As such, the extent to which an individual's alcohol use is associated with concurrent and future BPD symptoms has been relatively unstudied. The current study assessed year-to-year fluctuations in alcohol use and BPD symptoms in a large urban sample of girls from age 14 to age 17 (N = 2450). The primary aim was to examine whether increases in alcohol use were associated with increases in adolescent girls' BPD symptoms in the same year and in the following year. Results of fixed-effects (within-individual) models revealed that even while controlling for the time-varying impact of symptoms of both internalizing and externalizing disorders, prior and concurrent other substance use, and all time invariant, pre-existing differences between individuals, higher past-year alcohol use was associated with higher levels of BPD symptoms. Furthermore, this association did not vary by age, or by sociodemographic factors, including child race and socioeconomic status of the family. The results of this study indicate heightened risk for the exacerbation of BPD symptoms following increases in alcohol use frequency and highlight the potential utility of interventions targeting drinking behavior for preventing escalations in BPD symptoms.

Are Borderline Personality Symptoms Associated With Compulsive Sexual Behaviors Among Women in Treatment for Substance Use Disorders? An Exploratory Study

OBJECTIVE

Extant literature has documented a significant relationship between borderline symptoms and substance use disorders. As supported in past work, there is a significant theoretical relationship between borderline symptoms and compulsive sexual behaviors because both disorders share common underlying behaviors and traits. There is no known research that has examined the empirical relationship between borderline symptoms and compulsive sexual behaviors in a population with substance use disorders. To fill this important gap in the literature, this relationship was examined in the current study.

METHOD

Medical records from 120 women admitted to a private, residential treatment program for substance use disorders were reviewed for the current study.

RESULTS

Hierarchical multiple regression analysis demonstrated that borderline symptoms were significantly associated with compulsive sexual behaviors after controlling for alcohol use and problems, drug use and problems, age, and positive impression management.

CONCLUSION

Results from this study provide potentially important research and clinical implications, which could ultimately aid treatment and reduce relapse. However, continued research is needed to further examine the relationship between symptoms and compulsive sexual behaviors.

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.

Unidirectionality Between Borderline Personality Disorder Traits and Psychopathology in a Residential Addictions Sample: A Short-Term Longitudinal Study

Borderline personality disorder (BPD) is a barrier to treatment, yet the relationship between BPD features and other psychopathology symptoms in residential addictions treatment samples is understudied. Using a sample of adults enrolled in a residential drug treatment facility measured at baseline and 2-3 month follow-up, the authors examined the prospective relationship between BPD features and five indices of psychopathology: depression, anxiety, interpersonal sensitivity, hostility, and psychoticism, as well as psychopathology global severity. There was no effect of time on any of the forms of psychopathology, but females reported higher levels of BPD features, anxiety symptoms, and interpersonal sensitivity than males. A series of latent change score models indicated that BPD features predicted increases in all psychopathology scales at follow-up, while the reverse was not true. These results suggest that targeting BPD features in residents of drug treatment facilities may reduce the emergence of new psychopathology in the short term.

Dimensions of personality structure among patients with substance use disorders and co-occurring personality disorders: a comparison with psychiatric outpatients and healthy controls

BACKGROUND

Although dual diagnosis has been a topic of great scientific interest for a long time, few studies have investigated the personality traits that characterize patients suffering from substance use disorders and co-occurring personality disorders through a dimensional approach. The present study aimed to evaluate structural personality profiles among dual-diagnosis inpatients to identify specific personality impairments associated with dual diagnosis.

METHODS

The present study involved 97 participants divided into three groups: 37 dual-diagnosis inpatients, 30 psychiatric outpatients and 30 nonclinical controls. Dimensions of personality functioning were assessed and differences between groups were tested using Kernberg's dimensional model of personality.

RESULTS

Results showed that dual diagnosis was associated with the presence of difficulties in three main dimensions of personality functioning. Dual-diagnosis inpatients reported a poorly integrated identity with difficulties in the capacity to invest, poorly integrated moral values, and high levels of self-direct and other-direct aggression.

CONCLUSIONS

The present study highlighted that a dimensional approach to the study of dual diagnosis may clarify the personality functioning of patients suffering from this pathological condition. The use of the dimensional approach could help to advance research on dual diagnosis, and it could have important implications on clinical treatment programs for dual-diagnosis inpatients.

Ear Acupuncture for Co-Occurring Substance Abuse and Borderline Personality Disorder: An Aid to Encourage Treatment Retention and Tobacco Cessation

Objectives

Retention of individuals with co-occurring borderline personality disorder (BPD) and substance use disorders in treatment is known to be difficult. An outcome study of a tobacco-free 90-day inpatient dual-diagnosis treatment programme that uses several evidenced-based treatments in addition to ear acupuncture (acudetox) was undertaken to determine overall treatment effectiveness.

Methods

Between January 2009 and December 2011, 231 patients were treated in the programme, 88% with nicotine dependence and 79% with personality disorder diagnoses. All patients completing the programme were invited to enrol in a 1-year follow-up study in which they responded to monthly questionnaires to assess outcomes.

Results

185 patients (80%) successfully completed the programme. There was no correlation between successful programme completion and gender, race, age, primary drug dependence diagnosis or primary psychiatric diagnosis. The use of acudetox was positively correlated with successful completion (p=0.006). Of the 78 patients with BPD, 100% of men and 83% of women successfully completed the programme. Their use of acudetox was positively correlated with successful completion (p=0.026). At the end of the year, 140 questionnaires were returned: 51 patients with BPD reported outcomes similar to the group as a whole, with 55% sober and doing well.

Conclusions

The use of acudetox was positively correlated with both successful completion of the programme for those with BPD as well as successful tobacco cessation, which ultimately improves the ability to maintain sobriety.

Factors related to dropout from treatment in two outpatient treatments for borderline personality disorder

Patients with borderline personality disorder frequently drop out prematurely from psychotherapy. This study examined factors related to treatment attrition in 180 patients enrolled in a randomized controlled trial comparing 1 year of Dialectical Behavior Therapy (DBT) to General Psychiatric Management (GPM). Completers and dropouts were compared on a range of variables, including demographics, Axis I and Axis II disorders, anger and impulsivity, therapeutic alliance, and treatment condition. The participants were on average 30.36 years old and 86% were female. Regression analyses revealed that individuals who dropped out had higher levels of anger (p = .01), greater Axis I comorbidity (p = .03), poorer therapeutic alliance (p = .003), and a higher number of lifetime suicide attempts (p = .05). An interaction was also found between Axis I comorbidity and treatment condition, with significantly lower rates of dropout seen in individuals with high Axis I comorbidity who were assigned to GPM compared to those assigned to DBT (p < .001).

Difficulties in emotional regulation and substance use disorders: a controlled family study of bipolar adolescents

BACKGROUND

Self-regulatory mechanisms appear etiologically operant in the context of both substance use disorders (SUD) and bipolar disorder (BD), however, little is known about the role of deficits in emotional self-regulation (DESR) as it relates to SUD in context to mood dysregulation. To this end, we examined to what extent DESR was associated with SUD in a high-risk sample of adolescents with and without BD.

METHODS

203 families were assessed with a structured psychiatric interview. Using the Child Behavior Checklist (CBCL), a subject was considered to have DESR when he or she had an average elevation of 1 standard deviation (SD) above the norm on 3 clinical scale T scores (attention, aggression, and anxiety/depression; scores: 60 × 3 ≥ 180).

RESULTS

Among probands and siblings with CBCL data (N=303), subjects with DESR were more likely to have any SUD, alcohol use disorder, drug use disorder, and cigarette smoking compared to subjects with scores <180 (all p values <0.001), even when correcting for BD. We found no significant differences in the risk of any SUD and cigarette smoking between those with 1SD and 2SD above the mean (all p values >0.05). Subjects with cigarette smoking and SUD had more DESR compared to those without these disorders.

CONCLUSIONS

Adolescents with DESR are more likely to smoke cigarettes and have SUD. More work is needed to explore DESR in longitudinal samples.

Effectiveness and cost-effectiveness of dialectical behaviour therapy for self-harming patients with personality disorder: a pragmatic randomised controlled trial

BACKGROUND

A primary goal of dialectical behaviour therapy (DBT) is to reduce self-harm, but findings from empirical studies are inconclusive. The aim of this study was to assess the effectiveness and cost-effectiveness of DBT in reducing self-harm in patients with personality disorder.

METHODS

Participants with a personality disorder and at least 5 days of self-harm in the previous year were randomised to receive 12 months of either DBT or treatment as usual (TAU). The primary outcome was the frequency of days with self-harm; secondary outcomes included borderline personality disorder symptoms, general psychiatric symptoms, subjective quality of life, and costs of care.

RESULTS

Forty patients each were randomised to DBT and TAU. In an intention-to-treat analysis, there was a statistically significant treatment by time interaction for self-harm (incidence rate ratio 0.91, 95% CI 0.89-0.92, p < 0.001). For every 2 months spent in DBT, the risk of self-harm decreased by 9% relative to TAU. There was no evidence of differences on any secondary outcomes. The economic analysis revealed a total cost of a mean of 5,685 GBP (6,786 EUR) in DBT compared to a mean of 3,754 GBP (4,481 EUR) in TAU, but the difference was not significant (95% CI -603 to 4,599 GBP). Forty-eight per cent of patients completed DBT. They had a greater reduction in self-harm compared to dropouts (incidence rate ratio 0.78, 95% CI 0.76-0.80, p < 0.001).

CONCLUSIONS

DBT can be effective in reducing self-harm in patients with personality disorder, possibly incurring higher total treatment costs. The effect is stronger in those who complete treatment. Future research should explore how to improve treatment adherence.

The addition of a goal-based motivational interview to treatment as usual to enhance engagement and reduce dropouts in a personality disorder treatment service: results of a feasibility study for a randomized controlled trial

Background

There are high rates of treatment non-completion for personality disorder and those who do not complete treatment have poorer outcomes. A goal-based motivational interview may increase service users’ readiness to engage with therapy and so enhance treatment retention. We conducted a feasibility study to inform the design of a randomized controlled trial. The aims were to test the feasibility of recruitment, randomization and follow-up, and to conduct a preliminary evaluation of the effectiveness of the motivational interview.

Methods

Patients in an outpatient personality disorder service were randomized to receive the Personal Concerns Inventory plus treatment as usual or treatment as usual only. The main randomized controlled trial feasibility criteria were recruitment of 54% of referrals, and 80% of clients and therapists finding the intervention acceptable. Information was collected on treatment attendance, the clarity of therapy goals and treatment engagement.

Results

The recruitment rate was 29% (76 of 258). Of 12 interviewed at follow-up, eight (67%) were positive about the Personal Concerns Inventory. Pre-intervention interviews were conducted with 61% (23 out of 38) of the Personal Concerns Inventory group and 74% (28 out of 38) of the treatment as usual group. Participants’ therapy goals were blind-rated for clarity on a scale of 0 to 10. The mean score for the Personal Concerns Inventory group was 6.64 (SD = 2.28) and for the treatment as usual group 2.94 (SD = 1.71). Over 12 weeks, the median percentage session attendance was 83.33% for the Personal Concerns Inventory group (N = 17) and 66.67% for the treatment as usual group (N = 24). Of 59 eligible participants at follow-up, the Treatment Engagement Rating scale was completed for 40 (68%). The mean Treatment Engagement Rating scale score for the Personal Concerns Inventory group was 6.64 (SD = 2.28) and for the treatment as usual group 2.94 (SD = 1.71). Of the 76 participants, 63 (83%) completed the Client Service Receipt Inventory at baseline and 34 of 59 (58%) at follow-up.

Conclusion

Shortfalls in recruitment and follow-up data collection were explained by major changes to the service. However, evidence of a substantial positive impact of the Personal Concerns Inventory on treatment attendance, clarity of therapy goals and treatment engagement, make a full-scale evaluation worth pursuing. Further preparatory work is required for a multisite trial.

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.

Longitudinal twin study of borderline personality disorder traits and substance use in adolescence: developmental change, reciprocal effects, and genetic and environmental influences

Although the comorbidity between borderline personality disorder (BPD) and substance abuse is well established, there are few longitudinal studies that have examined its developmental origins or whether the comorbidity is due to common genetic or environmental risk factors. To fill this gap, we used a large sample of female adolescent twins (N = 1,280) to examine the developmental course, reciprocal influences, and the genetic and environmental factors underlying the co-occurrence of BPD traits and substance use from age 14 to 18. Rank-order stability was moderate to high for both BPD traits (r = .58) and substance use (r = .51), whereas mean levels of substance use increased substantially from age 14 to 18 (d = 0.77) and BPD traits showed a small decline (d = -0.21). BPD traits and substance use exhibited concurrent and prospective associations; however, the longitudinal associations dropped to nonsignificance after accounting for the temporal stability of each trait. Twin analyses revealed that shared environmental factors accounted for the association between BPD traits and substance use at age 14, but genetic factors accounted for the association at age 18. These results indicate that, at least in adolescence, the comorbidity between BPD traits and substance use is a consequence of common risk factors rather than due to one being a casual antecedent of the other.

The impact of borderline personality disorder on residential substance abuse treatment dropout among men

BACKGROUND

Research is increasingly focusing on identifying factors distinguishing patients who complete vs. dropout of residential substance abuse treatment. One potentially relevant factor that has received relatively little attention is borderline personality disorder (BPD).

METHODS

This study sought to examine the effect of BPD on residential substance abuse treatment dropout within a sample of 159 male patients with substance use disorders-a population often understudied with regard to BPD and at high-risk for treatment dropout. Patients were administered a structured diagnostic interview to establish BPD diagnoses. Patients were then followed throughout the course of residential substance abuse treatment to identify those who completed treatment and those who prematurely dropped out of treatment.

RESULTS

Patients with BPD were significantly more likely to prematurely dropout of treatment, and this finding remained even when taking into account relevant covariates (i.e., court-ordered treatment status, contract duration, and major depressive disorder). Further, patients with BPD were more likely to experience center-initiated dropout as opposed to voluntary withdrawal from treatment.

CONCLUSIONS

These findings add to the literature on BPD-SUD co-occurrence, suggesting that the presence of co-occurring BPD among male SUD patients may increase the risk for dropout from residential substance abuse treatment, necessitating targeted interventions focused on decreasing dropout within this patient subgroup.

Distress tolerance moderates the relationship between negative affect intensity with borderline personality disorder levels

A number of studies have suggested that negative emotionality and negative affect intensity play key roles in the development and maintenance of borderline personality disorder (BPD). However, more recent research indicates that one's response to affective discomfort may be an even more important variable in the pathogenesis of BPD than either negative emotionality or negative affect intensity per se. As such, the current study aimed to empirically test the moderating role of 2 well-validated laboratory measures of the ability to tolerate psychological distress (distress tolerance) in the relationship of negative emotionality and negative affect intensity with BPD levels. Results provide laboratory-based evidence for a moderating effect of distress tolerance on the relationship of negative emotionality and negative affect intensity with levels of BPD. Specifically, the 2 former variables were related to levels of BPD among those with low distress tolerance. The current results add support to existing developmental frameworks of BPD and suggest the importance of modifying one's response to affective distress along with levels of negative emotionality in treatment settings.

Personality disorders and retention in a therapeutic community for substance dependence

Although therapeutic community (TC) treatment is a promising intervention for substance use disorders, a primary obstacle to successful treatment is premature attrition. Because of their prevalence within substance use treatment facilities, personality disorder (PD) diagnoses have been examined as predictors of treatment completion. Prior research on TC outcomes has focused almost exclusively on antisocial personality disorder (ASPD), and the results have been mixed. This study extends previous research by examining the impact of the 10 Axis II PDs on early (first 30 days) attrition as well as overall time to dropout in a 9-month residential TC. Survival analyses indicated that borderline was the only PD negatively related to overall program retention. In contrast, ASPD, as well as histrionic PD, were related to very early attrition, but not to overall program retention. Early assessment and identification of at-risk individuals may improve treatment retention and outcome for TC treatment.

Open, aware, and active: contextual approaches as an emerging trend in the behavioral and cognitive therapies

A wave of new developments has occurred in the behavioral and cognitive therapies that focuses on processes such as acceptance, mindfulness, attention, or values. In this review, we describe some of these developments and the data regarding them, focusing on information about components, moderators, mediators, and processes of change. These "third wave" methods all emphasize the context and function of psychological events more so than their validity, frequency, or form, and for these reasons we use the term "contextual cognitive behavioral therapy" to describe their characteristics. Both putative processes, and component and process evidence, indicate that they are focused on establishing a more open, aware, and active approach to living, and that their positive effects occur because of changes in these processes.

Treatment completion in psychotherapy for borderline personality disorder: a systematic review and meta-analysis

OBJECTIVE

Psychotherapy for borderline personality disorder (BPD) has been associated with problematically low treatment completion rates.

METHOD

PsycInfo and Medline were systematically searched to identify studies providing information on treatment completion in psychotherapy models that have been shown to be effective for BPD. A meta-analysis of treatment completion rates and a narrative analysis of factors predicting dropout were conducted.

RESULTS

Forty-one studies were included, with completion rates ranging from 36% to 100%- a substantial between-study heterogeneity. Random effects meta-analyses yielded an overall completion rate of 75% (95% CI: 68-82%) for interventions of <12 months duration, and 71% (95% CI: 65-76%) for longer interventions. Egger's test for publication bias was significant for both analyses (P ≤ 0.01). Study characteristics such as treatment model and treatment setting did not explain between-study heterogeneity. In individual studies, factors predicting dropout status included commitment to change, the therapeutic relationship and impulsivity, whilst sociodemographics were consistently non-predictive.

CONCLUSION

Borderline personality disorder should no longer be associated with high rates of dropout from treatment. However, the substantial variation in completion rates between studies remains unexplained. Research on the psychological processes involved in dropping out of treatment could further improve dropout rates.

Outcome of dialectical behaviour therapy for concurrent eating and substance use disorders

AIM

The current study examined the preliminary efficacy of dialectical behaviour therapy (DBT) adapted for concurrent eating disorders (EDs) and substance use disorders (SUDs).

METHOD

A matched randomized controlled trial was carried out with 25 female outpatients diagnosed with concurrent ED and SUD. Participants randomized to the intervention condition received DBT, whereas those randomized to the control condition received treatment as usual (TAU), both for a period of 1 year. A series of measures related to disordered eating, substance use and depression were administered to the participants at the beginning of treatment and at 3, 6, 9 and 12 months into treatment, followed by 3-month and 6-month follow-up assessments.

FINDINGS

Participants randomized to the DBT condition evidenced a superior retention rate relative to their counterparts in the TAU condition at various study time points, including post-treatment (80% versus 20%) and follow-up (60% versus 20%). Due to the unexpected elevated dropout rates and the worsening of ED-SUD symptomatology in the TAU condition, recruitment efforts were terminated early. Results from the DBT condition revealed that the intervention had a significant positive effect on behavioural and attitudinal features of disordered eating, substance use severity and use, negative mood regulation and depressive symptoms. Finally, increases in participants' perceived ability to regulate and cope with negative emotional states were significantly associated with decreases in emotional eating and increases in levels of confidence in ability to resist urges for substance use.

CONCLUSION

Results suggest that the adapted DBT might hold promise for treating individuals with concurrent ED and SUD.

KEY PRACTITIONER MESSAGE

The current study is the first study to report positive effects of DBT on individuals with concurrent eating and substance use disorders. Although the results require replication and extension, they suggest that the DBT may be promising for this population. The results suggest that clinicians treating individuals with concurrent eating and substance use problems should be particularly cautious of poor treatment retention and treatment complications. The results bear upon the highly salient and important issue of whether individuals with concurrent substance use need to be excluded from research studies and treatment programmes.

Non-completion of personality disorder treatments: a systematic review of correlates, consequences, and interventions

Non-completion of treatment is a major concern in the provision of therapies for people diagnosed with personality disorder, with adverse consequences for services, therapists, and other patients. Of even greater concern is that non-completion of treatment may limit the effectiveness of therapy for individuals. Our main aim in this study was to conduct a systematic review of the literature on psychosocial treatments for personality disorder to identify factors associated with treatment non-completion. Two subsidiary aims were to identify studies that reported the relative outcomes of treatment completion and non-completion, and to identify studies that evaluated psychosocial interventions specifically aimed at improving retention in treatment. This information is potentially useful in informing selection criteria and directing efforts towards improving treatment engagement. Twenty-five empirical studies of factors predicting treatment non-completion were identified. The median non-completion rate was 37%. A range of patient characteristics, need factors, and environment factors were identified as associated with non-completion. However, the studies could not be considered homogeneous group for meta-analysis. Four studies investigated the effects of treatment non-completion, showing an association with adverse outcomes. Only two studies of interventions specifically aimed at reducing non-completion were identified. Implications for clinical practice and research are discussed.

[Evidence-based psychotherapy: addiction and personality disorders as comorbidities]

A large number of studies have shown that various psychotherapeutic methods have a positive effect on the course of addiction and personality disorders when they are treated separately. Co-morbid occurrence of both disorders is common but a chronologically separated treatment often leads to renewed occurrence of the symptoms of the initially treated disorder. Failures of abstinence motivation, severe drug craving and the activation of dysfunctional behavior patterns frequently lead to renewed consumption of addictive substances and thus endanger the further course of treatment. So far, evidence of effectiveness exists only for dialectic behavior therapy and dual focus schema therapy. This article summarizes the current state of knowledge and introduces both methods by highlighting the core therapeutic strategies.

Psychotherapy of personality disorders and concomitant substance dependence

PURPOSE OF REVIEW

Psychotherapy of patients with personality disorder and concomitant substance dependence requires an integrative approach. Although a number of studies have evaluated psychotherapy for one of these disorders, only few studies have described the effectiveness of treatment programs in comorbid patients. These limited findings provide a basis for the further development of treatments for personality disorder and concomitant substance dependence. This review gives an overview of the current state of research in this field.

RECENT FINDINGS

Although a large number of evaluation studies tested the effectiveness of several therapies for alcohol dependence, far fewer evaluated nonalcohol substance dependence. There are very few evaluations of the efficacy of psychotherapy for other forms of drug dependence. Only dialectical behavior therapy and dual-focus schema therapy have been tested for the treatment of personality disorder and substance dependence.

SUMMARY

To date, two randomized controlled trials in 59 female-only patients with borderline personality disorder and substance abuse provided the best evidence-based data for the effectiveness of dialectical behavior therapy. For dual-focus schema therapy, a single randomized controlled trial indicated a curative effect in a small group of patients with personality disorder and substance dependence. Although the results of these studies are encouraging, further clinical trials need to be conducted in larger populations including male participants.
