Brief individual experiential schema therapy in adult outpatients with cluster C personality disorders: Does it work?

This study investigated the effectiveness of brief individual experiential schema therapy (ST) in 12 adult outpatients with cluster C personality disorders (PD) using randomised multiple baseline design. Waitlist period was followed by five explorative sessions, 18 experiential ST sessions, two treatment follow-up (FU) booster sessions and a 6-month FU assessment. Overall well-being (ORS), behavioural treatment goals and negative core beliefs were assessed 60-91 times, global symptomatic distress (BSI) six times. PD severity (SCID-5-PD) was pre-post-analysed. Randomisation and non-parametric tests showed large significant effects (d = 1.08-2.38, r = .53-.66) on all outcomes at treatment-FU and 6-month FU assessment. This is the first study providing preliminary evidence of effectiveness of brief individual experiential ST for patients with cluster C PD, tentatively challenging the common tenet that long treatment duration is required. Due to limitations, replication is recommended.

Brain activation during an emotional task in participants with PTSD and borderline and/or cluster C personality disorders.

INTRODUCTION: Although comorbidity of post-traumatic stress disorder (PTSD) with borderline personality disorder (BPD) and/or cluster C personality disorders (CPD) is common, neural correlates of this comorbidity are unknown. METHODS: We acquired functional MRI scans during an emotional face task in participants with PTSD + CPD (n = 34), PTSD + BPD (n = 24), PTSD + BPD + CPD (n = 18) and controls (n = 30). We used ANCOVAs and Bayesian analyses on specific ROIs in a fearful vs. scrambled faces contrast. We also investigated associations with clinical measures. RESULTS: There were no robust differences in brain activation between the groups with ANCOVAs. Transdiagnostically, we found a negative association between severity of dissociation and right insula and right dmPFC activation, and emotion regulation problems with right dmPFC activation. Bayesian analyses showed credible evidence for higher activation in all ROIs in the PTSD + BPD + CPD group compared to PTSD + BPD and PTSD + CPD. DISCUSSION: Our Bayesian and correlation analyses support new dimensional conceptualizations of personality disorders.

An Exploratory Study of MMPI-2-RF Personality and Psychopathology Profiles of Adults with Autism Spectrum Disorder without Intellectual Disability.

Objective: More empirical research is needed to disentangle the phenotypes of autism spectrum disorder (ASD) and cluster C personality symptomatology (CCPD), as both show similarities in their clinical presentation. We explored personality and psychopathology dimensions as conceptualized in contemporary dimensional taxonomies (i.e., hierarchical taxonomy of psychopathology; HiTOP) in adults with ASD without intellectual disability operationalized by the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF). Method: Applying secondary analytic processes using clinical data, we cross-examined the MMPI-2-RF profiles of adults with ASD (n = 28) compared to adults with Cluster C personality disorders (CCPD; n = 28) and a control group (n = 28) by conducting nonparametric tests and assessing effect sizes. Results: The profiles of the ASD and CCPD groups evidenced to be similar, and both average clinical profiles diverged from the average control group profiles by elevated levels of demoralization, internalizing, and somatization symptomatology. There were small differences between the average profiles of adults with ASD and adults with CCPD. Additional research using dimensional measures of psychopathology could elucidate the dimensional phenotypes of ASD and CCPD. Conclusions: Based on the results in this study, the MMPI-2-RF may not meaningfully discriminate between the two clinical presentations, with the exception of various externalizing scales.

Design of an RCT on cost-effectiveness of group schema therapy versus individual schema therapy for patients with Cluster-C personality disorder: the QUEST-CLC study protocol.

BACKGROUND: Given the high prevalence of Cluster-C Personality Disorders (PDs) in clinical populations, disease burden, high societal costs and poor prognosis of comorbid disorders, a major gain in health care can be achieved if Cluster-C PDs are adequately treated. The only controlled cost-effectiveness study published so far found Individual Schema Therapy (IST) to be superior to Treatment as Usual (TAU). Group ST (GST) might improve cost-effectiveness as larger numbers can be treated in (>50%) less time compared to IST. However, to date there is no RCT supporting its (cost-) effectiveness. The overall aim of this study is to assess the evidence for GST for Cluster-C PDs and to improve treatment allocation for individual patients. Three main questions are addressed: 1) Is GST for Cluster-C PDs (cost-)effective compared to TAU? 2) Is GST for Cluster-C PDs (cost-) effective compared to IST? 3) Which patient-characteristics predict better response to GST, IST, or TAU? METHODS: In a multicenter RCT, the treatment conditions GST, IST, and TAU are compared in 378 Cluster-C PD patients within 10 sites. GST and IST follow treatment protocols and are completed within 1 year. TAU is the optimal alternative treatment available at the site according to regular procedures. Severity of the Cluster-C PD is the primary outcome, assessed with clinical interviews by independent raters blind for treatment. Functioning and wellbeing are important secondary outcomes. Assessments take place at week 0 (baseline), 17 (mid-GST), 34 (post-GST), 51 (post-booster sessions of GST), and 2 years (FU). Patient characteristics predicting better response to a specific treatment are studied, e.g., childhood trauma, autistic features, and introversion. A tool supporting patients and clinicians in matching treatment to patient will be developed. An economic evaluation investigates the cost-effectiveness and cost-utility from a societal perspective. A process evaluation by qualitative methods explores experiences of participants, loved ones and therapists regarding recovery, quality of life, and improving treatment. DISCUSSION: This study will determine the (cost-)effectiveness of treatments for Cluster-C PDs regarding treatment type as well as optimal matching of patient to treatment and deliver insight into which aspects help Cluster-C-PD patients recover and create a fulfilling life.

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. TRIAL REGISTRATION: Clinical Trials, NCT03833453 & NCT03833531 .

Group schema therapy for patients with cluster-C personality disorders: A case study on avoidant personality disorder.

This article presents a clinical illustration of group schema therapy (GST) for cluster-C personality disorders (CL-C PDs) to provide therapists an example on how one can perform GST for CL-C PDs and break through persistent avoidance and control mechanisms. A summary of evidence supporting the effectiveness of GST for CL-C PD's is given followed by an overview of basic principles of schema therapy and GST. A case presentation next illustrates the application of GST principles and interventions in the GST CL-C protocol, which improve clients understanding of emotional core needs and development of adaptive ways of getting needs better met, instead of avoiding life. Implications of the case for future applications of GST for CL-C PDs are discussed.

Patients with borderline personality disorder and comorbid PTSD show biased attention for threat in the facial dot-probe task.

BACKGROUND AND OBJECTIVES: Biased attention to threat is likely to play a crucial role in the dysfunctional emotion-related information processing in borderline personality disorder (BPD). However, the role of comorbid posttraumatic stress disorder (PTSD) has not yet been fully disentangled. METHODS: BPD patients with (n = 24) and without (n = 46) PTSD, 35 patients with Cluster-C personality disorder and 52 non-patients participated in the facial dot-probe task with angry, happy and neutral faces during automatic (100 ms), controlled (600 ms), and later (1200 ms) stages of information processing. RESULTS: BPD patients showed a greater congruency effect to angry faces during the controlled stage of processing than controls. Specifically, in BPD with PTSD compared to controls, this effect was due to difficulties disengaging from threat, indicated by slower reaction times to incongruent angry targets compared to neutral trials. Regarding automatic and later stages of information processing, there was no attentional bias (AB) in BPD. None of the groups revealed biased attention for happy faces at any stages of information processing. LIMITATIONS: We did not include a control group of PTSD patients without BPD. Therefore, we cannot rule out that the present AB in BPD is mainly due to PTSD-specific psychopathology. CONCLUSIONS: These findings provide first evidence for an AB towards angry faces and difficulties disengaging from these threat-related social cues in adult BPD patients. Although BPD patients in general demonstrated an AB when compared with controls, this effect was especially pronounced for BPD with PTSD, suggesting a significant effect of trauma-related psychopathology on social attention in BPD.

Subjective emotional responses to IAPS pictures in patients with borderline personality disorder, cluster-C personality disorders, and non-patients.

According to Linehan (1993), emotion dysregulation is a central feature of borderline personality disorder (BPD). We hypothesized that patients with BPD are emotionally hyperresponsive. For BPD treatment, it is important to evaluate this hypothesis, because, if it is supported, therapeutic interventions could be designed to help patients to better manage hyperemotional reactions. We investigated the subjective reactions (in terms of valence and arousal) of patients with BPD to visual emotional stimuli of the International Affective Picture System (IAPS). We hypothesized that, compared to patients with Cluster-C personality disorders and non-patients, BPD patients would show higher scores on the arousal dimension and higher negative scores on the valence dimension when rating IAPS pictures with varying degrees of arousal and valence. Ratings of valence and arousal for 40 IAPS pictures were collected from 39 borderline personality disorder (BPD), 36 patients diagnosed with Cluster-C personality disorders (PD), and a group of 226 non-patients. Contrary to expectations, BPD patients did not differ from the non-patients. This indicates that their self-report scores do not reflect hypersensitivity. We found that patients with BPD showed lower scores on arousal than Cluster-C PD patients. The scores on valence suggested that Cluster-C PD patients also experienced more positive emotions than BPD patients.

Crying in borderline personality disorder patients.

Emotion dysregulation and hyperreactivity are considered central features of Borderline Personality Disorder (BPD). We assumed that such emotion dysregulation is also reflected in increased crying behavior of these patients and, consequently, hypothesized that BPD patients (N = 62), compared to Cluster C personality disorder patients (Cluster C-PD; N = 25) and non-patients (N = 54), would show higher scores on crying measures. To evaluate crying behavior, we used a set of specially designed tools. Compared to non-patients, BPD patients showed the anticipated higher crying frequency despite a similar crying proneness and ways of dealing with tears. They also reported less awareness of the influence of crying on others. However, Cluster C-PD patients showed a very similar pattern of findings. Overall, our results suggest that the increased crying of BPD patients likely results from environmental factors or the misperception of situations, rather than from stable traits. Remarkable is that the observed discrepancies in crying behavior compared to non-patients seem to be similar for Cluster-C PDs and BPD.

Borderline and cluster C personality disorders manifest distinct physiological responses to psychosocial stress.

BACKGROUND: Maladaptive emotional control is a defining feature of personality disorders. Yet little is known about the underlying physiological dynamics of emotional reactivity to psychosocial stress across distinct personality disorders. The current study compared subjective emotional responses with autonomic nervous system and HPA axis physiological responses to psychosocial stress in women with cluster C personality disorder (CPD) and borderline personality disorder (BPD). METHODS: Subjective mood ratings, salivary cortisol, heart rate (HR), and skin conductance level (SCL) were assessed before, during, and after exposure to a standardized psychosocial stress paradigm (Trier Social Stress Test, TSST) in 26 women with BPD, 20 women with CPD, and 35 healthy female controls. Subjects were free of any medication including hormonal contraceptives, had a regular menstrual cycle, and were tested during the luteal phase of their menstrual cycle. RESULTS: Both CPD and BPD patients reported a similar burden of subjective mood disturbance. However, only BPD patients demonstrated reduced baseline cortisol levels with a blunted cortisol and HR reactivity to the TSST. In addition, BPD patients exhibited a generalized increase of SCL. No significant differences in baseline or TSST reactivity of cortisol, HR, or SCL were observed between CPD patients and healthy controls. CONCLUSION: These findings indicate that patients with BPD have significant alterations in their physiological stress reactivity, which is notably distinct from patients with CPD and those of healthy controls.

The influence of stress on social cognition in patients with borderline personality disorder.

BACKGROUND: Borderline personality disorder (BPD) is characterized by severe difficulties in interpersonal relationships and emotional functioning. Theories of BPD suggest that individuals with BPD have heightened emotional sensitivity, increased stress reactivity, and problems in making sense of intentions of others. In this study we investigated stress reactivity in BPD and its interference with social cognition, and tested whether any differences are specific for BPD or are inherent to personality disorders in general. METHODS: We investigated 22 patients with BPD, 23 patients with Cluster C personality disorder (CPD), and 24 nonpatients on facial emotion recognition and social evaluation before and after stress induction based on the Trier Social Stress Test (TSST). RESULTS: The results show that stress increased subjective negative emotions in the BPD group to a larger extent than in the other groups, whereas physiological responses were attenuated. Importantly stress induction increased negative evaluations about others, but surprisingly to a similar extent in the BPD and CPD groups as in the nonpatient control group. In addition facial emotion recognition performance was higher after than before stress, but no significant group differences were observed. CONCLUSION: These results suggest that heightened psychological reactivity in BPD co-occurs with attenuated physiological responses to psychosocial stress and that stress affects social cognition to a similar extent in BPD as in others.
