EXPLORING PERSONALITY DIAGNOSIS STABILITY FOLLOWING ACUTE PSYCHOTHERAPY FOR CHRONIC POSTTRAUMATIC STRESS DISORDER

Imagery Rescripting (ImRs) and Eye Movement Desensitization and Reprocessing (EMDR) as treatment of childhood-trauma related post-traumatic stress disorder (Ch-PTSD) in adults: effects on Schema Modes

Background: Many patients with post-traumatic stress disorder (PTSD) due to childhood trauma (Ch-PTSD) also suffer from comorbid personality pathology. Little is known about the effectiveness of treatments for Ch-PTSD in reducing the comorbid personality pathology. Schema Modes are an operationalization of personality pathology according to schema therapy and can be measured with the Schema Mode Inventory (SMI). Therefore, we evaluated the effects of two treatments for adult patients with Ch-PTSD on Schema Modes.Method: Participants (n = 114) of the Imagery Rescripting and Eye Movement Desensitization and Reprocessing (IREM) Randomized Clinical Trial (Boterhoven de Haan, K. L., Lee, C. W., Fassbinder, E., Voncken, M. J., Meewisse, M., Van Es, S. M., Menninga, S., Kousemaker, M., & Arntz, A. (2017). Imagery rescripting and eye movement desensitization and reprocessing for treatment of adults with childhood trauma-related post-traumatic stress disorder: IREM study design. BMC Psychiatry, 17(1), 1-12, Boterhoven de Haan, K. L., Lee, C. W., Fassbinder, E., van Es, S. M., Menninga, S., Meewisse, M.-L., Rijkeboer, M., Kousemaker, M., & Arntz, A. (2020). Imagery rescripting and eye movement desensitization and reprocessing as treatment for adults with post-traumatic stress disorder from childhood trauma: Randomised clinical trial. The British Journal of Psychiatry, 217(5), 609-615) with Ch-PTSD who filled in the SMI next to other outcomes, were randomly allocated to a 12-session treatment of Imagery Rescripting (ImRs) or Eye Movement Desensitization and Reprocessing (EMDR). The SMI was collected at waitlist, pre-treatment, mid-treatment, posttreatment, and 8-week and 1-year follow-up.Results: For both treatments, patients reported large reductions in the Maladaptive Schema Modes and improvements in the Adaptive Schema Modes (Cohen's d = .94-1.18) from pre-treatment to posttreatment, 8-week follow-up, and 1-year follow-up. No statistically significant differences were found between ImRs and EMDR regarding changes in Schema Modes over time. No significant changes were observed during the waitlist period.Conclusions: ImRs and EMDR showed improvements in Schema Modes when primarily targeting Ch-PTSD. The results indicate the possible value of both treatments in reducing comorbid personality pathology.

Feasibility of EMDR toward Personality Functioning in Older Adults with PTSD

OBJECTIVES

Severe posttraumatic stress disorder (PTSD) in older adults (≥60 years) has been found to be associated with maladaptive personality functioning and personality disorders (PD). Emerging evidence in adults supports that reprocessing adverse events with Eye Movement Desensitization and Reprocessing (EMDR) could improve personality functioning and reduce full PDdiagnosis.

METHODS

A multicenterfeasibilitystudy in 24 older PTSD-patients receiving weekly EMDR-sessions for either 3, 6 or 9 months. A linear-mixed-model was used with personality functioning (SIPP-SF) as dependent variable and time, PTSD-severity (CAPS-5), and "othertreatment" as predictor variables. Secondary, pre- and posttreatment percentages were calculated for the PDspresence.

RESULTS

Symptom changes over time showed a significant influence of CAPS-5 on SIPP-SF (b = -1.40, 95% CI=[-2.48 to -0.33], p = .012), no significant effect of time for total SIPP-SF, and a significant improvement of SIPP-SF "identityintegration"-scale over time (b = 9.20, 95% CI=[0.97-17.42], p = .029). There was a marginal significant effect of "othertreatment" (b = 8.42, 95% CI=[-0.30-17.13], p = .058). There was 31% full PDs-decrease.

CONCLUSIONS

Observed improvements in personality functioning from pre to post EMDRtreatment were explained by PTSD-severity. Identityintegration improved significantly over time. Results suggest that participants with "othertreatment" showed more severe baseline-pathology and thus lower personality functioning.

CLINICAL IMPLICATIONS

EMDR, in addition to being a feasible treatment option for older adults with PTSD, improves personality functioning and reduces the presence of PDs over time.'

Trauma-focused and personality disorder treatment for posttraumatic stress disorder and comorbid cluster C personality disorder: a randomized clinical trial

Background: Posttraumatic stress disorder (PTSD) is associated with high rates of cluster C personality disorders (PD), which may negatively affect PTSD treatment. It is unknown whether concurrent treatment for PTSD and comorbid PD leads to superior treatment effects, compared to standard trauma-focused treatment.Objective: The objective was to test the efficacy of adding personality disorder treatment (group schema therapy; GST) to individual trauma-focused treatment (imagery rescripting; ImRs).Method: A two-arm randomized clinical trial (1:1 allocation ratio) was conducted between 2018 and 2023 at two sites of a mental health institution in the Netherlands. Raters were blind to treatment allocation. Adult outpatients with PTSD and comorbid cluster C personality disorders were randomized to receive either ImRs (12-18 sessions) or ImRs + GST (12-18 ImRs + 52-58 GST). The main outcome was PTSD severity one year after start of treatment measured with the Clinician-Administered PTSD Scale for DSM-5.Results: Of 130 patients (mean [SD] age = 40.6 [11.2], 110 [85%] females), 66 were assigned to ImRs and 64 to ImRs + GST. At 12 months, there were large decreases in PTSD severity (dImRs = 2.42, 95%CI = 1.97-2.87; dImRs + GST = 2.44, 95%CI = 1.99-2.90), but there was no significant difference between conditions (d = 0.02, 95%CI = -0.33-0.36, p = .944). Reductions in personality disorder symptoms and all other secondary outcomes were observed in both conditions. There were no significant differences between conditions on any of the secondary outcomes at 12 months.Conclusion: The more intensive concurrent trauma-focused and personality disorder treatment (ImRs + GST) was not superior to trauma-focused treatment alone (ImRs) for patients with PTSD and comorbid CPD. This suggests that trauma-focused treatment is the preferred primary treatment in patients presenting with both internalizing personality disorder and PTSD, reserving the stepping up to more intensive psychotherapy aimed at the personality disorder as a second line of treatment.Trial registration: ClinicalTrials.gov identifier: NCT03833531.

Case report: Brief, intensive EMDR therapy for borderline personality disorder: results of two case studies with one year follow-up

Background

Exposure to adverse childhood events plays an important role in the development of borderline personality disorder (BPD). Emerging evidence suggests that trauma-focused therapy using eye movement desensitization and reprocessing (EMDR) can be beneficial for patients with BPD symptoms. To date, the effects of brief, intensive EMDR treatment for this target group have not been investigated in this population.

Objective

This study aimed to evaluate the effects of a brief and intensive trauma-focused therapy course using EMDR therapy in two patients diagnosed with BPD who did not fulfill the diagnostic criteria for post-traumatic stress disorder (PTSD). It was hypothesized that this approach would be associated with a decline in the core symptoms of BPD, and that this would have an enduring long-term effect on patients' diagnostic status.

Method

Ten sessions of EMDR therapy were carried out across four consecutive treatment days, with the aim of processing patients' core adverse childhood experiences. Both A-criterion-worthy memories (without intrusive reliving) and non-A-criterion-worthy memories that were considered responsible for the patients' most prominent symptoms were targeted. The effects of EMDR therapy on trauma symptom severity and BPD diagnostic status (as established by the Structured Clinical Interview DSM-5) were determined. Additionally, the effects on psychological distress, quality of life, and difficulties in emotion regulation were determined at intake, post-treatment, and at 3-, 6-, and 12-months follow-up.

Results

Both patients showed a strong decline in psychological distress and difficulties in emotion regulation, and reported an improvement in their quality of life. At post-treatment, and at 3-, 6-, and 12-months follow-up they no longer met the DSM-5 criteria for BPD.

Conclusion

The findings of this small case study are in line with mounting evidence that a brief track of intensive trauma-focused therapy can result in long-term remission in patients with BPD. EMDR therapy seems to be a promising treatment approach for patients with BPD; however, the results need to be replicated in clinical trials.

Self-rated personality disorder symptoms do not predict treatment outcome for posttraumatic stress disorder in routine clinical care

OBJECTIVE

To test the hypothesis that self-rated personality disorder (PD) symptoms are a significant and clinically relevant predictor of treatment outcomes in a naturalistic treatment setting specialized in trauma-focused treatment using a single-group pretest-posttest design.

METHOD

Treatment-seeking patients reporting clinical levels of posttraumatic stress disorder (PTSD) symptoms filled out questionnaires at intake and after treatment. The primary outcome was change in PTSD severity after treatment, measured by the PTSD Checklist for DSM-5 (PCL-5). PD symptoms were measured with the Structured Clinical Interview for DSM-5 Screening Personality Questionnaire (SCID-5-SPQ). Secondary outcomes were general mental health problems, treatment response, number of sessions and dropout.

RESULTS

N = 1174 patients (59% female, baseline PCL-5 score M [SD] = 53.0 [10.8]) were included for the primary analysis. Regression analysis revealed that PD symptoms explained 0.4% of variance in PTSD symptom change (p = .066). After controlling for baseline PTSD symptoms, PD symptoms explained 0.0% of variance (p = .311). The fully adjusted model including baseline PTSD symptom severity, age, gender, cumulative exposure to potentially traumatic experiences, PD symptoms, and number of sessions together explained 5% of the observed variance in PTSD symptom change. Baseline PTSD severity was the only significant predictor and negatively predicted outcome. Sensitivity analyses with imputed data from N = 2694 cases yielded comparable results. Finally, secondary analyses showed that PD symptoms did not predict significant or clinically relevant changes in treatment response status, general mental health problems, dropout rates or number of sessions.

CONCLUSION

The findings provide no evidence that self-rated PD symptoms predict treatment outcomes for patients suffering from clinical levels of PTSD symptoms in a naturalistic treatment setting specializing in trauma-focused treatment. Self-report screening for these symptoms to inform clinicians about expected effects of PTSD treatment is not supported by the evidence.

Effects of intensive trauma-focused treatment of individuals with both post-traumatic stress disorder and borderline personality disorder

Background: Research indicates that intensive trauma-focused therapy can be effective in alleviating symptoms of post-traumatic stress disorder (PTSD) and borderline personality disorder (BPD). However, these studies have relied on self-report of BPD symptoms and follow-up data are scarce.Objective: The purpose of this feasibility study was to determine the effects of an intensive trauma-focused treatment programme on the severity of PTSD and BPD symptoms and the diagnostic status up to a 12-month follow-up.Methods: A total of 45 (60% female) individuals meeting the diagnostic criteria of both PTSD and BPD participated in an intensive eight-day trauma-focused treatment programme which combined prolonged exposure and EMDR therapy in an inpatient treatment setting. Severity of PTSD and BPD symptoms were assessed at pre-treatment, post-treatment, 6 months, and 12 months after treatment (CAPS-5, BPDSI-IV). Diagnostic status was determined using clinical interviews (CAPS-5 and SCID-5-P) at pre-treatment and 12-month follow-up.Results: Of all participants, 93.3% had been exposed to physical abuse, and 71.1% to sexual abuse prior to the age of 12 years. PTSD and BPD symptom severity significantly decreased from pre- to post-treatment (Cohen's ds: 1.58 and 0.98, respectively), and these results were maintained at 6- (ds: 1.20 and 1.01) and 12-month follow-up (ds: 1.53 and 1.36). Based upon CAPS-5, 69.2% no longer met the diagnostic criteria of PTSD at 12-month follow-up, while according to the SCID-5-P 73.1% no longer fulfilled the diagnostic criteria of BPD at that time. No significant worsening of symptoms occurred.Conclusion: The findings of this study, which is the first to examine the effects of psychotherapeutic treatment of PTSD on the presence of a borderline personality disorder one year after treatment, add support to the notion that a brief intensive trauma-focused treatment can be a valuable option for individuals suffering from both PTSD and BPD.

Does EMDR Therapy Have an Effect on Memories of Emotional Abuse, Neglect and Other Types of Adverse Events in Patients with a Personality Disorder? Preliminary Data

BACKGROUND

Little is known about the effectiveness of trauma-focused therapies for memories of events not meeting the A-criterion of post-traumatic stress disorder (PTSD).

OBJECTIVE

Determining the effect of EMDR therapy on memories of emotional abuse, neglect and other types of adverse events in patients with a personality disorder (PD).

METHOD

We conducted a secondary analysis of the data from our study, which aimed to determine the effectiveness of five sessions of EMDR therapy in 49 patients with a PD. Patients were divided into three different groups depending on their most prevalent type of adverse event. Data were analyzed with Generalized Estimating Equations.

RESULTS

Of all patients, 49% reported emotional neglect, 22.4% emotional abuse and 26.5% other types. Only one patient reported memories that predominantly fulfilled the A-criterion of PTSD. After five sessions of EMDR therapy, medium to large treatment effects for memories related to neglect (ds between 0.52 and 0.79), medium treatment effects for memories involving emotional abuse (ds between 0.18 and 0.59) and other types of adverse events were found (ds between 0.18 and 0.53). No significant differences in symptom reduction associated with the application of EMDR therapy among memories involving these three different types of adverse events could be revealed.

CONCLUSIONS

The results support the notion that EMDR therapy is not only an effective therapy for memories related to A-criteria-worthy events, but that it also has a symptom-reducing effect on memories involving other types of adverse events. This suggests that EMDR might be a valuable addition to the treatment of PD without PTSD.

Impact of comorbid personality disorders on psychotherapy for post-traumatic stress disorder: systematic review and meta-analysis

Background: Although personality disorders are common in PTSD patients, it remains unclear to what extent this comorbidity affects PTSD treatment outcome. Objective: This constitutes the first meta-analysis investigating whether patients with and without comorbid personality disorders can equally benefit from psychotherapy for PTSD. Method: A systematic literature search was conducted in PubMed, EMBASE, PsychINFO and Cochrane databases from inception through 31 January 2020, to identify clinical trials examining psychotherapies for PTSD in PTSD patients with and without comorbid personality disorders (PROSPERO reference CRD42020156472). Results: Of the 1830 studies identified, 12 studies reporting on 918 patients were included. Effect sizes were synthesized using a random-effects model. Patients with comorbid personality disorders did not have significantly higher baseline PTSD severity (Hedges' g = 0.23, 95%CI -0.09-0.55, p = .140), nor were at higher risk for dropout from PTSD treatment (RR = 1.19, 95%CI 0.83-1.72, p = .297). Whilst pre- to post-treatment PTSD symptom improvements were large in patients with comorbid PDs (Hedges' g = 1.31, 95%CI 0.89-1.74, p < .001) as well as in patients without comorbid PDs (Hedges' g = 1.57, 95%CI 1.08-2.07, p < .001), personality disorders were associated with a significantly smaller symptom improvement at post-treatment (Hedges' g = 0.22, 95%CI 0.05-0.38, p = .010). Conclusion: Although the presence of personality disorders does not preclude a good treatment response, patients with comorbid personality disorders might benefit less from PTSD treatment than patients without comorbid personality disorders.

Neural correlates of treatment effect and prediction of treatment outcome in patients with PTSD and comorbid personality disorder: study design

BACKGROUND

Neural alterations related to treatment outcome in patients with both post-traumatic stress disorder (PTSD) and comorbid personality disorder are unknown. Here we describe the protocol for a neuroimaging study of treatment of patients with PTSD and comorbid borderline (BPD) or cluster C (CPD) personality disorder traits. Our specific aims are to 1) investigate treatment-induced neural alterations, 2) predict treatment outcome using structural and functional magnetic resonance imaging (MRI) and 3) study neural alterations associated with BPD and CPD in PTSD patients. We hypothesize that 1) all treatment conditions are associated with normalization of limbic and prefrontal brain activity and hyperconnectivity in resting-state brain networks, with additional normalization of task-related activation in emotion regulation brain areas in the patients who receive trauma-focused therapy and personality disorder treatment; 2) Baseline task-related activation, together with structural brain measures and clinical variables predict treatment outcome; 3) dysfunction in task-related activation and resting-state connectivity of emotion regulation areas is comparable in PTSD patients with BPD or CPD, with a hypoconnected central executive network in patients with PTSD+BPD.

METHODS

We aim to include pre- and post-treatment 3 T-MRI scans in 40 patients with PTSD and (sub) clinical comorbid BPD or CPD. With an expected attrition rate of 50%, at least 80 patients will be scanned before treatment. MRI scans for 30 matched healthy controls will additionally be acquired. Patients with PTSD and BPD were randomized to either EMDR-only or EMDR combined with Dialectical Behaviour Therapy. Patients with PTSD and CPD were randomized to Imaginary Rescripting (ImRs) or to ImRs combined with Schema Focused Therapy. The scan protocol consists of a T1-weighted structural scan, resting state fMRI, task-based fMRI during an emotional face task and multi-shell diffusion weighted images. For data analysis, multivariate mixed-models, regression analyses and machine learning models will be used.

DISCUSSION

This study is one of the first to use neuroimaging measures to predict and better understand treatment response in patients with PTSD and comorbid personality disorders. A heterogeneous, naturalistic sample will be included, ensuring generalizability to a broad group of treatment seeking PTSD patients.

Clinical Efficacy and Cost-Effectiveness of Imagery Rescripting Only Compared to Imagery Rescripting and Schema Therapy in Adult Patients With PTSD and Comorbid Cluster C Personality Disorder: Study Design of a Randomized Controlled Trial

Background: Posttraumatic stress disorder (PTSD) is a serious and relatively common mental disorder causing a high burden of suffering. Whereas evidence-based treatments are available, dropout and non-response rates remain high. PTSD and Cluster C personality disorders (avoidant, dependent or obsessive-compulsive personality disorder; CPD) are highly comorbid and there is evidence for suboptimal treatment effects in this subgroup of patients. An integrated PTSD and CPD treatment may be needed to increase treatment efficacy. However, no studies directly comparing the efficacy of regular PTSD treatment and treatment tailored to PTSD and comorbid CPD are available. Whether integrated treatment is more effective than treatment focused on PTSD alone is important, since (1) no evidence-based guideline for PTSD and comorbid CPD treatment exists, and (2) treatment approaches to CPD are costly and time consuming. Present study design describes a randomized controlled trial (RCT) directly comparing trauma focused treatment with integrated trauma focused and personality focused treatment. Methods: An RCT with two parallel groups design will be used to compare the clinical efficacy and cost-effectiveness of "standalone" imagery rescripting (n = 63) with integrated imagery rescripting and schema therapy (n = 63). This trial is part of a larger research project on PTSD and personality disorders. Predictors, mediators and outcome variables are measured at regular intervals over the course of 18 months. The main outcome is PTSD severity at 12 months. Additionally, machine-learning techniques will be used to predict treatment outcome using biopsychosocial variables. Discussion: This study protocol outlines the first RCT aimed at directly comparing the clinical efficacy and cost-effectiveness of imagery rescripting and integrated imagery rescripting and schema therapy for treatment seeking adult patients with PTSD and comorbid cluster C personality pathology. Additionally, biopsychosocial variables will be used to predict treatment outcome. As such, the trial adds to the development of an empirically informed and individualized treatment indication process. Clinical Trial registration: ClinicalTrials.gov, NCT03833531.

Eye movement desensitization and reprocessing (EMDR) in patients with a personality disorder

Background: Little is known about the effects of targeting memories of adverse (childhood) events in people with a personality disorder (PD). Objective: Determining the effectiveness of brief EMDR therapy in individuals with PD. Method: In a randomized-controlled trial, 97 outpatients with a PD as main diagnosis were allocated to either five (90 minutes) sessions of EMDR therapy (n = 51) or a waiting list (WL) control condition (n = 46) followed by 3 months of treatment as usual for their PD. Individuals with posttraumatic stress disorder (PTSD) were excluded. Measurements were performed on psychological symptoms, psychological distress, and personality dysfunctioning. Outcomes were compared at baseline, post-treatment, and at 3-month follow up. Data were analysed as intent-to-treat with linear mixed models. Results: EMDR therapy yielded significant improvements with medium to large effect sizes for the primary outcomes after treatment, i.e. psychological symptoms (EMDR: d =.42; control group: d =.07), psychological distress (EMDR: d =.69; control group: d =.29), and personality functioning (EMDR: d =.41; control group: d = -.10) within groups. At 3-month follow-up, after 3 months of TAU, improvements were maintained. Significant differences were found between both groups regarding all outcome measures in favour of the EMDR group at post-treatment (ds between -.62 and -.65), and at follow-up, after 3 months of TAU (ds between -.45 and -.53). Conclusions: The results suggest that EMDR therapy can be beneficial in the treatment of patients with PDs. More rigorous outcome research examining long-term effects and using a longer treatment track is warranted.

Separation anxiety in PTSD: A pilot study of mechanisms in patients undergoing IPT

INTRODUCTION

Separation anxiety disorder (SAD) comprises one aspect of attachment dysregulation or insecurity. Although SAD aggravates posttraumatic stress disorder (PTSD) risk, no clinical research has tracked how many patients with PTSD have SAD, its clinical associations, or its response to PTSD treatment. Our open trial of interpersonal psychotherapy (IPT) for veterans with PTSD assessed these SAD domains.

METHODS

Twenty-nine veterans diagnosed with chronic PTSD on the Clinician-Administered PTSD Scale were assessed for SAD using the Structured Clinical Interview for Separation Anxiety Symptoms (SCI-SAS), and for Symptom-Specific Reflective Function (SSRF), another dysregulated-attachment marker capturing patients' emotional understanding of their symptoms. Patients received 14 IPT sessions for PTSD with assessments at baseline, Week 4 (SCI-SAS and SSRF), and termination for SAD, PTSD, and depression.

RESULTS

At baseline, 69% of patients met SAD criteria. Separation anxiety did not correlate with baseline PTSD severity, depressive severity, or age when traumatized; patients with and without SAD had comparable PTSD and depression severity. Patients with baseline comorbid SAD who completed IPT (N = 17) reported significantly improved adult separation anxiety (p = .009). Adult SAD improvements predicted depressive improvement (p = .049). Patients with SAD showed a stronger relationship between early SSRF gains and subsequent adult SAD improvement (p = .021) compared with patients without SAD.

DISCUSSION

This first exploration of dysregulated/insecure attachment features among patients with PTSD found high SAD comorbidity and adult SAD improvement among patients with SAD following IPT. Highly impaired attachment patients normalized attachment posttreatment: 14-session IPT improved attachment dysregulation. This small study requires replication but begins to broaden clinical understanding of separation anxiety, attachment dysregulation, and PTSD.

EMDR as a Treatment Approach of PTSD Complicated by Comorbid Psychiatric, Somatic, and Cognitive Disorders: A Case Report of an Older Woman With a Borderline and Avoidant Personality Disorder

Traumatic life events can result in severe psychiatric conditions among which posttraumatic stress disorder (PTSD) is the most prevalent. Due to high comorbidity with other psychiatric diagnoses, PTSD treatment is challenging. In older adults, the presentation of PTSD symptoms is especially complicated because of even higher comorbidity, higher rates with other mental disorders, and cognitive and somatic conditions. Eye movement desensitization and reprocessing (EMDR) is an evidence-based treatment for trauma in younger adults. There is limited empirical research on the treatment effects of EMDR in older adults. Moreover, the impact of successful EMDR treatment on the comorbid disorders, especially personality and cognitive dysfunctions, is unclear. In this case report, EMDR treatment effects for late-onset PTSD with comorbid borderline and avoidant personality disorders, as well as cognitive disorders and multiple somatic problems, will be presented in an older woman.

EMDR in Older Adults With Posttraumatic Stress Disorder

Recognition of posttraumatic stress disorder (PTSD) in older adults is often difficult due to its complicated presentation. Once recognized, trauma symptoms can, in accordance with (inter)national guidelines, be successfully treated with eye movement desensitization and reprocessing (EMDR) therapy. However, limited empirical research has been done on the expression and treatment of PTSD in older adults. This article explains trauma and age in the context of psychotherapy. It discusses the interaction between age and pathology and summarizes the cognitive issues related to age, PTSD, and anxiety. It provides practical suggestions for how these can be addressed in treatment. Age-related challenges related to motivation are identified with practical suggestions for addressing them. The case illustrates the necessary additions and subtractions for older adults, with clear explanations and instructions. This article points the way for future research.

What is the effect on comorbid personality disorder of brief panic-focused psychotherapy in patients with panic disorder?

BACKGROUND

No studies of psychotherapies for panic disorder (PD) have examined effects on comorbid personality disorders (PersD), yet half such patients have a PersD.

METHODS

In a randomized trial for PD with and without agoraphobia comparing Cognitive-Behavioral Therapy (CBT) and Panic-Focused Psychodynamic Psychotherapy (PFPP), PersD was assessed pre-to-post treatment with the Structured Clinical Interview for the Diagnosis of Axis-II Disorders (SCID-II). For patients completing therapy (n = 118, 54 with PersD), covariance between panic and SCID-II criteria improvements was analyzed. SCID-II diagnostic remission and recovery were evaluated. Comparative efficacy of PFPP versus CBT for improving PersD was analyzed both for the average patient, and as a function of PersD severity.

RESULTS

37 and 17% of PersD patients experienced diagnostic PersD remission and recovery, respectively. Larger reductions in PersD were related to more panic improvement, with a modest effect size (r = 0.28). Although there was no difference between treatments in their ability to improve PersD for the average patient (d = 0.01), patients meeting more PersD criteria did better in PFPP compared to CBT (P = .007), with PFPP being significantly superior at 11 criteria and above (d = 0.66; 3 more criteria lost).

CONCLUSIONS

PersD presenting in the context of primary PD rarely resolves during psychotherapies focused on PD, and change in PersD only moderately tracks panic improvements, indicating non-overlap of the constructs. Patients receiving panic-focused psychotherapies may require additional treatment for their PersD. PFPP may be superior at improving severe PersD, but replication of this finding is required.

History of sexual trauma moderates psychotherapy outcome for posttraumatic stress disorder

BACKGROUND

Moderators of differential psychotherapy outcome for posttraumatic stress disorder (PTSD) are rare, yet have crucial clinical importance. We tested the moderating effects of trauma type for three psychotherapies in 110 unmedicated patients with chronic DSM-IV PTSD.

METHODS

Patients were randomized to 14 weeks of prolonged exposure (PE, N = 38), interpersonal psychotherapy (IPT, N = 40), or relaxation therapy (RT, N = 32). The Clinician-Administered PTSD Scale (CAPS) was the primary outcome measure. Moderator candidates were trauma type: interpersonal, sexual, physical. We fit a regression model for week 14 CAPS as a function of treatment (a three-level factor), an indicator of trauma type presence/absence, and their interactions, controlling for baseline CAPS, and evaluated potential confounds.

RESULTS

Thirty-nine (35%) patients reported sexual, 68 (62%) physical, and 102 (93%) interpersonal trauma. Baseline CAPS scores did not differ by presence/absence of trauma types. Sexual trauma as PTSD criterion A significantly moderated treatment effect: whereas all therapies had similar efficacy among nonsexually-traumatized patients, IPT had greater efficacy among sexually traumatized patients (efficacy difference with and without sexual trauma: IPT vs. PE and IPT vs. RT P's < .05), specifically in PTSD symptom clusters B and D (P's < .05).

CONCLUSIONS

Few studies have assessed effects of varying trauma types on effects of differing psychotherapies. In this exploratory study, sexual trauma moderated PTSD outcomes of three therapies: IPT showed greater benefit for sexually traumatized patients than PE or RT. The IPT focuses on affect to help patients determine trust in their current environments may particularly benefit patients who have suffered sexual assault.

Working Alliance, Interpersonal Problems, and Depressive Symptoms in Tele-Interpersonal Psychotherapy for HIV-infected Rural Persons: Evidence for Indirect Effects

OBJECTIVE

Interpersonal psychotherapy (IPT) has demonstrated efficacy for the treatment of depression, yet little is known about its therapeutic mechanisms. As a specific treatment, IPT has been shown to directly reduce depressive symptoms, although it is unclear whether these reductions occur via interpersonal changes. Within IPT, the potential role of the working alliance, a common factor, as a predictor of depression and interpersonal changes is also unclear.

METHOD

Participants were 147 depressed persons living with HIV in rural communities of 28 U.S. states enrolled in a randomized clinical trial. Seventy-five patients received up to 9 sessions of telephone-administered IPT (tele-IPT) plus standard care and 72 patients received standard care only. Two models were tested; one included treatment condition (tele-IPT vs. control) and another included the working alliance as independent variables.

RESULTS

The first model found an indirect effect whereby tele-IPT reduced depression via decreased social avoidance. There was a direct effect between tele-IPT and reduced depression. In the second model, the working alliance influenced depressive symptom relief via reductions in social avoidance. Both goal and task working alliance subscales were indirectly associated with reductions in depressive symptoms, also through reductions in social avoidance. There were no direct effects involving the working alliance. Tele-IPT's influence on depressive symptom reduction was primarily through a direct effect, whereas the influence of working alliance depression was almost entirely via an indirect effect through interpersonal problems.

CONCLUSION

Study findings have implications for IPT when intervening with depressed rural people living with HIV/AIDS over the telephone.

Longitudinal Associations between Posttraumatic Stress Disorder Severity and Personality Disorder Features among Female Rape Survivors

This study evaluated how change in posttraumatic stress disorder (PTSD) symptoms was associated with residualized change in comorbid personality disorder (PD) features and vice versa over the course of 5-10 years. The sample was comprised of 79 female rape survivors who met criteria for PTSD and who were a part of a larger study examining the effects of trauma-focused therapy. PTSD was assessed with the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) version of the Clinician-Administered PTSD Scale [CAPS-IV (1)] and PD features were assessed with the DSM-IV dimensional PD scales on the Schedule for Non-adaptive and Adaptive Personality [SNAP (2)]. PTSD symptom severity and PD features were assessed at baseline and between 5 and 10 years after completing treatment. Multiple regression analyses revealed that PTSD symptom change was related to residualized change in PD severity for paranoid, schizotypal, antisocial, borderline, avoidant, and dependent PD (βs ranged from -0.23 to -0.33; all ps < 0.05). In addition, for borderline and antisocial PDs, longitudinal stability of the PD was attenuated among those with greater PTSD symptom improvement (i.e., the relationship between these PDs over time was altered as a function of PTSD symptom change; βs ranged from -0.27 to -0.29; all ps < 0.05). Similarly, change in severity of paranoid, schizotypal, antisocial, avoidant, and obsessive-compulsive (OC) PD was associated with residualized change in PTSD symptoms (βs ranged from -0.32 to -0.41; all ps < 0.05), and the longitudinal stability of PTSD was attenuated as a product of change in OC PD (β = -0.27; p < 0.02). These findings suggest that these two sets of disorders may impact one another substantially, altering the course of even chronic, characterological conditions. This carries important clinical implications for the treatment of both PTSD and PDs.
