Effectiveness of Predominantly Group Schema Therapy and Combined Individual and Group Schema Therapy for Borderline Personality Disorder: A Randomized Clinical Trial

IMPORTANCE

Schema therapy (ST), delivered either in an individual or group format, has been compared with other active treatments for borderline personality disorder (BPD). To our knowledge, the 2 formats have not been compared with treatment as usual (TAU) or with each other. Such comparisons help determine best treatment practices.

OBJECTIVE

To evaluate whether ST is more effectively delivered in a predominantly group or combined individual and group format and whether ST is more effective than optimal TAU for BPD.

DESIGN, SETTING, AND PARTICIPANTS

In this multicenter, 3-arm randomized clinical trial conducted at 15 sites in 5 countries (Australia, Germany, Greece, the Netherlands, and the UK), outpatients aged 18 to 65 years who had BPD were recruited between June 29, 2010, and May 18, 2016, to receive either predominantly group ST (PGST), combined individual and group ST (IGST), or optimal TAU. Data were analyzed from June 4, 2019, to December 29, 2021.

INTERVENTIONS

At each site, cohorts of 16 to 18 participants were randomized 1:1 to PGST vs TAU or IGST vs TAU. Both ST formats were delivered over 2 years, with 2 sessions per week in year 1 and the frequency gradually decreasing during year 2. Assessments were collected by blinded assessors.

MAIN OUTCOMES AND MEASURES

The primary outcome was the change in BPD severity over time, assessed with the Borderline Personality Disorder Severity Index (BPDSI) total score. Treatment retention was analyzed as a secondary outcome using generalized linear mixed model survival analysis.

RESULTS

Of 495 participants (mean [SD] age, 33.6 [9.4] years; 426 [86.2%] female), 246 (49.7%) received TAU, 125 (25.2%) received PGST, and 124 (25.0%) received IGST (1 of whom later withdrew consent). PGST and IGST combined were superior to TAU with regard to reduced BPD severity (Cohen d, 0.73; 95% CI, 0.29-1.18; P < .001). For this outcome, IGST was superior to TAU (Cohen d, 1.14; 95% CI, 0.57-1.71; P < .001) and PGST (Cohen d, 0.84; 95% CI, 0.09-1.59; P = .03), whereas PGST did not differ significantly from TAU (Cohen d, 0.30; 95% CI, -0.29 to 0.89; P = .32). Treatment retention was greater in the IGST arm than in the PGST (1 year: 0.82 vs 0.72; 2 years: 0.74 vs. 0.62) and TAU (1 year: 0.82 vs 0.73; 2 years: 0.74 vs 0.64) arms, and there was no significant difference between the TAU and PGST arms (1 year: 0.73 vs 0.72; 2 years: 0.64 vs 0.62).

CONCLUSIONS AND RELEVANCE

In this randomized clinical trial, IGST was more effective and had greater treatment retention compared with TAU and PGST. These findings suggest that IGST is the preferred ST format, with high retention and continuation of improvement in BPD severity after the completion of treatment.

Occupational heat-related illness emergency department visits and inpatient hospitalizations in the southeast region, 2007-2011

BACKGROUND

Heat-related illness (HRI) is an occupational health risk for many outdoor, and some indoor, workers.

METHODS

Emergency department (ED) and inpatient hospitalization (IH) data for 2007-2011 from nine southeast states were analyzed to identify occupational HRI numbers and rates, demographic characteristics, and co-morbid conditions.

RESULTS

There were 8,315 occupational HRI ED visits (6.5/100,000 workers) and 1,051 IHs (0.61/100,000) in the southeast over the study period. Out-of-state residents comprised 8% of ED visits and 12% of IHs. Rates for both, ED visits and IHs were significantly elevated in males and blacks. Younger workers had elevated rates for ED visits, while older workers had higher IH rates.

CONCLUSIONS

This is the first study to evaluate occupational HRI ED visits and IHs in the southeast region and indicates the need for enhanced heat-stress prevention policies in the southeast. Findings from this study can be used to direct state health department tracking and evaluation of occupational HRI.

Design of an international multicentre RCT on group schema therapy for borderline personality disorder

BACKGROUND

Borderline personality disorder (BPD) is a severe and highly prevalent mental disorder. Schema therapy (ST) has been found effective in the treatment of BPD and is commonly delivered through an individual format. A group format (group schema therapy, GST) has also been developed. GST has been found to speed up and amplify the treatment effects found for individual ST. Delivery in a group format may lead to improved cost-effectiveness. An important question is how GST compares to treatment as usual (TAU) and what format for delivery of schema therapy (format A; intensive group therapy only, or format B; a combination of group and individual therapy) produces the best outcomes.

METHODS/DESIGN

An international, multicentre randomized controlled trial (RCT) will be conducted with a minimum of fourteen participating centres. Each centre will recruit multiple cohorts of at least sixteen patients. GST formats as well as the orders in which they are delivered to successive cohorts will be balanced. Within countries that contribute an uneven number of sites, the orders of GST formats will be balanced within a difference of one. The RCT is designed to include a minimum of 448 patients with BPD. The primary clinical outcome measure will be BPD severity. Secondary clinical outcome measures will include measures of BPD and general psychiatric symptoms, schemas and schema modes, social functioning and quality of life. Furthermore, an economic evaluation that consists of cost-effectiveness and cost-utility analyses will be performed using a societal perspective. Lastly, additional investigations will be carried out that include an assessment of the integrity of GST, a qualitative study on patients' and therapists' experiences with GST, and studies on variables that might influence the effectiveness of GST.

DISCUSSION

This trial will compare GST to TAU for patients with BPD as well as two different formats for the delivery of GST. By combining an evaluation of clinical effectiveness, an economic evaluation and additional investigations, it will contribute to an evidence-based understanding of which treatment should be offered to patients with BPD from clinical, economic, and stakeholders' perspectives.

Quality of life in anorexia nervosa, bulimia nervosa and eating disorder not-otherwise-specified

BACKGROUND

This study aimed to assess differences in Quality of Life (QoL) across eating disorder (ED) diagnoses, and to examine the relationship of QoL to specific clinical features.

RESULTS

199 patients with a diagnosed ED completed the Clinical Impairment Assessment (CIA) [Cognitive Behavior Therapy and Eating Disorders, 315-318, 2008] and the Eating Disorders Examination (EDE) [Int J Eat Disord 6:1-8]. Differences between diagnostic groups were examined, as were differences between restrictive and binge-purge subtypes. CIA scores and EDE scores were positively correlated and higher in groups with binge-purge behaviours. CIA scores were not correlated with BMI, illness duration or frequency of bingeing/purging behaviours, except in the binge-purge AN group, where CIA scores negatively correlated with BMI.

CONCLUSIONS

Patients with EDs have poor QoL and impairment increases with illness severity. Patients with binge/purge diagnoses are particularly impaired. It remains unclear which clinical features best predict the degree of impairment experienced by patients with EDs.

Emotional and social mind training: a randomised controlled trial of a new group-based treatment for bulimia nervosa

Objective

There is a need to improve treatment for individuals with bulimic disorders. It was hypothesised that a focus in treatment on broader emotional and social/interpersonal issues underlying eating disorders would increase treatment efficacy. This study tested a novel treatment based on the above hypothesis, an Emotional and Social Mind Training Group (ESM), against a Cognitive Behavioural Therapy Group (CBT) treatment.

Method

74 participants were randomised to either ESM or CBT Group treatment programmes. All participants were offered 13 group and 4 individual sessions. The primary outcome measure was the Eating Disorder Examination (EDE) Global score. Assessments were carried out at baseline, end of treatment (four months) and follow-up (six months).

Results

There were no differences in outcome between the two treatments. No moderators of treatment outcome were identified. Adherence rates were higher for participants in the ESM group.

Discussion

This suggests that ESM may be a viable alternative to CBT for some individuals. Further research will be required to identify and preferentially allocate suitable individuals accordingly.

Theory of mind in bulimia nervosa

OBJECTIVE

This study aimed to investigate theory of mind (ToM) in individuals with bulimia nervosa (BN), an area neglected by empirical research despite social functioning difficulties in this disorder and evidence of ToM deficits in people with anorexia nervosa (AN).

METHOD

ToM was assessed in 48 BN and 34 Eating Disorder Not Otherwise Specified BN-type (EDNOS-BN) outpatients and 57 healthy controls (HCs) using the Reading the Mind in the Eyes and the Reading the Mind in the Films (RMF), an ecologically valid task novel to BN research.

RESULTS

Overall performance in BN and EDNOS-BN groups was equivalent to HCs on both tasks. Individuals with BN had enhanced negative emotion recognition on the RMF.

DISCUSSION

Individuals with AN and BN have distinct socio-cognitive profiles. Further research into social cognition is required to establish the link between interpersonal difficulties and psychopathology in people with BN.

A study of neurocognition in bulimia nervosa and eating disorder not otherwise specified-bulimia type

Neurocognition in bulimia nervosa (BN) is under-researched. This study investigated aspects of attention (d2-Letter Cancellation Task), inhibitory control (Stroop and go/no-go task), and decision making (Game of Dice Task) in 40 people with BN, 30 with eating disorder not otherwise specified-BN type (EDNOS-BN), and 65 healthy controls (HCs). The National Adult Reading Test (NART) and Depression Anxiety Stress Scale (DASS-21) were also administered. Analyses of covariance (covariates: age, NART, and DASS-21) showed that people with BN and EDNOS-BN performed as well as HCs on all tasks. Attention task performance was poorer in the EDNOS-BN than in the BN group.

Social cognition in bulimia nervosa: a systematic review

OBJECTIVE

Clinical accounts and previous evidence suggest that socio-emotional impairments may be present in people with bulimia nervosa (BN). The aim of this paper was to systematically review studies of social cognition, and to evaluate whether social cognitive deficits exist in BN.

METHOD

Keywords were identified using an existing model of social cognition (Green et al., 2007) [16], and used to search for relevant papers in three online databases. Records were then screened according to a priori inclusion/exclusion criteria.

RESULTS

Five papers reporting seven social cognition tasks were identified as pertinent to the review. All involved either theory of mind ability or emotional processing skills. Participants with BN had impaired performance on the Levels of Emotional Awareness Scale and showed greater attentional bias than controls on an emotional Stroop task. There were no overall group differences for any other tasks, although there were small differences for some specific test items.

CONCLUSIONS

Basic social cognition does not appear to be impaired in people with BN. Future research should make use of more complex, ecologically valid measures, and consider the relationship between task performance and everyday social functioning.

Measuring self-report obsessionality in anorexia nervosa: Maudsley Obsessive-Compulsive Inventory (MOCI) or obsessive-compulsive inventory-revised (OCI-R)?

Self-report measures are often used in research and clinical practise as they efficiently gather a large amount of information. With growing numbers of self-report measures available to target single constructs, it is important to revisit one's choice of instrument to be sure that the most valid and reliable measure is employed. The Maudsley Obsessive-Compulsive Inventory (MOCI) and the Obsessive-Compulsive Inventory-Revised (OCI-R) were administered to 223 female participants: 30 inpatients with anorexia nervosa (AN), 62 community cases with AN, 69 community cases weight restored from AN and 62 healthy controls. Both measures distinguished between clinical and healthy groups; however, the OCI-R showed superior internal reliability. Additionally, the OCI-R measures six (to the MOCI's four) obsessive-compulsive constructs, and uses a more sensitive response format (likert scale vs. categorical). It is recommended that the OCI-R be employed as the self-report instrument of choice for assessing obsessive-compulsive pathology in those with AN.

Rumination and future thinking in depression

OBJECTIVES

Future thinking is an important domain of cognitive functioning, with reduced ability to imagine positive future events associated with hopelessness in depression and parasuicide. Rumination has been shown to exacerbate negative cognitive biases in depression, and to reduce likelihood estimations for positive future events. We examine the hypothesis that, in depressed patients, rumination would reduce the ability to imagine positive future events, whilst increasing the ability to imagine negative future events.

METHOD

The ability to imagine positive and negative future events was assessed using the future thinking paradigm (MacLeod, Rose, & Williams, 1993). Depressed and nondepressed participants completed the future thinking task after being randomly allocated to either a rumination or distraction manipulation (Nolen-Hoeksema & Morrow, 1993). Mood was measured before and after the manipulation. Participants also completed a standard verbal fluency task.

RESULTS

In the depressed group, compared to distraction, rumination increased both negative and positive future thinking, although the effect was only significant for negative future thinking once baseline levels of hopelessness were controlled for. These findings are consistent with the prediction that rumination would increase negative future thinking, but inconsistent with the prediction that rumination would reduce positive future thinking. Previous findings that, compared to controls, depressed patients generated fewer positive future events were replicated.

CONCLUSION

Ruminative self-focus leads to greater negative future thinking in depressed patients, further confirming that rumination exacerbates negative cognitive biases in depression. The relationship between rumination and positive future thinking was unexpected, but might potentially reflect a general priming of self-related information by rumination.

Obsessive-compulsive beliefs and magical ideation in eating disorders

OBJECTIVES

Similarities in patterns of cognition and behaviour between patients with eating disorders and those with obsessive-compulsive disorder (OCD) have long been recognized, and comorbidity between these disorders has been shown to be high. However, there has been little investigation of the cognitive content shared between eating disorders and OCD. It has been suggested that a cognitive analysis of the overlap between the disorders may help to increase understanding of each, and have potentially useful clinical implications. The present study aimed to investigate the presence of obsessive-compulsive beliefs and magical ideation (MI) in a group of eating-disordered participants.

METHOD

One hundred seventy-seven volunteers with a history of or current eating disorder completed the Obsessive Beliefs Questionnaire (OBQ), the Interpretation of Intrusions Inventory (IlI) and the Magical ideation scale (MIS).

RESULTS

Eating-disordered participants demonstrated levels of the beliefs measured comparable to or higher than those with OCD.

CONCLUSIONS

The results supported the hypothesis that the belief domains investigated are relevant to eating-disordered individuals. This has interesting theoretical and clinical implications. Further research will be required to elucidate the role of these types of cognitions in the relationship between eating disorders and OCD, and to clarify their role in the psychopathology of eating disorders.

Therapeutic writing as an intervention for symptoms of bulimia nervosa: effects and mechanism of change

OBJECTIVE

This study explored the effects on bulimic symptomatology of a writing task intended to reduce emotional avoidance.

METHOD

Eighty individuals reporting symptoms of bulimia completed, by e-mail, a therapeutic or control writing task. Participants completed questionnaires on bulimic symptoms, mood, and potential moderating and mediating factors, and were followed up after 4 and 8 weeks. Writing content was explored using a word count package and qualitative framework analysis.

RESULTS

Bulimic symptoms decreased in both groups, although in both groups the number of participants who improved was approximately equal to the number who did not improve. Symptom decreases were associated with increases in perceived mood regulation abilities, and decreases in negative beliefs about emotions. Participants preferred internet delivery to face to face discussion.

DISCUSSION

For individuals experiencing symptoms of bulimia, the effects of therapeutic writing did not differ significantly from effects of a control writing task.

Attenuation of muscle damage by preconditioning with muscle hyperthermia 1-day prior to eccentric exercise

This study investigated the hypothesis that muscle damage would be attenuated in muscles subjected to passive hyperthermia 1 day prior to exercise. Fifteen male students performed 24 maximal eccentric actions of the elbow flexors with one arm; the opposite arm performed the same exercise 2-4 weeks later. The elbow flexors of one arm received a microwave diathermy treatment that increased muscle temperature to over 40 degrees C, 16-20 h prior to the exercise. The contralateral arm acted as an untreated control. Maximal voluntary isometric contraction strength (MVC), range of motion (ROM), upper arm circumference, muscle soreness, plasma creatine kinase activity and myoglobin concentration were measured 1 day prior to exercise, immediately before and after exercise, and daily for 4 days following exercise. Changes in the criterion measures were compared between conditions (treatment vs. control) using a two-way repeated measures ANOVA with a significance level of P < 0.05. All measures changed significantly following exercise, but the treatment arm showed a significantly faster recovery of MVC, a smaller change in ROM, and less muscle soreness compared with the control arm. However, the protective effect conferred by the diathermy treatment was significantly less effective compared with that seen in the second bout performed 4-6 weeks after the initial bout by a subgroup of the subjects (n = 11) using the control arm. These results suggest that passive hyperthermia treatment 1 day prior to eccentric exercise-induced muscle damage has a prophylactic effect, but the effect is not as strong as the repeated bout effect.

A conservative approach for proximal interphalangeal joint arthroplasty

Access to the proximal interphalangeal joint of the finger for arthroplasty is difficult without detaching its stabilizers or dividing the tendons that cross it, which then require repair and slow rehabilitation. We describe a method that conserves both, so facilitating post-operative rehabilitation.A C-shaped incision is made on the dorsum of the finger. The lateral bands of the extensor expansion are separated from the central slip proximally to the extensor hood. They are then retracted to expose the condyles of the proximal phalanx, which are excised. The PIP joint is then dislocated between the central slip and a lateral band allowing the remainder of the head to be excised. The middle and proximal phalanges are then prepared to accept the prosthesis. The prosthesis is then inserted and the joint is reduced. The lateral bands of the extensor mechanism are sutured back to the central slip before the skin is closed.

Cortical evoked potentials in the ruptured anterior cruciate ligament

The sensory role of the intact and ruptured anterior cruciate ligament was studied by the use of cortical evoked potentials during arthroscopy. This showed a response from the intact ligament in four patients that was reproducible. This response was consistent with those obtained from stimulation of the ipsilateral posterior tibial nerve. No response was elicited from either the femoral or tibial stump of ruptured ligaments using the same technique in six patients who had ruptured their anterior cruciate ligament (two femoral and four mid-substance ruptures). We believe that this demonstrates that there is no functional nervous tissue within the anterior cruciate ligament after rupture.

Orthopaedic clinical note. Patella metastases: a case report

Here we report the first noted case of a small cell carcinoma of the lung (oat cell carcinoma) presenting as metastases in the patella. Malignancies of the patella, primary or secondary, are rare. First presentation of a malignancy with metastases in the patella has only been recorded once previously.

Quality assurance in mental health: the QUARTZ system

This paper is concerned with how quality might be assured in mental health services. It includes an account of why a concern with quality and quality assurance procedures are now high on the agenda of the Health Service. A quality assurance programme requires a decision about what elements of a service to monitor, what information is relevant, how it can be collected, and a system for acting on the results. This paper provides a brief review of the kind of information that has been considered relevant and the methods that have been used to collect it. In addition, the principles underlying good and comprehensive quality assurance programmes will be outlined and the development of a particular system, known as QUARTZ, which has attempted to incorporate these principles, described briefly.

Preferential inspection of views of 3-D model heads

The importance of different perspective views for the recognition of model heads was studied. In experiment 1 subjects were instructed to learn the appearance of six heads placed individually on a turntable free to rotate through 360 degrees. Subjects did not distribute their time evenly but focussed their inspection on particular views (the full face view and a view close to the profile). Despite differential inspection of these two views during the learning phase, the face, half profile, and profile views were recognized with equal efficiency in a subsequent recognition task with static views. Experiment 2 used the inspection paradigm to investigate view preference during the recognition of heads from memory. In this experiment subjects were asked to learn the appearance of three heads each seen rotating at an even speed. In a subsequent retrieval task the subjects actively inspected six model heads on the turntable and were asked to differentiate the three heads previously seen rotating from three novel heads. The pattern of inspection in this retrieval task was equivalent to that in experiment 1. Results suggest that during the encoding into memory subjects construct descriptions of specific prototypical views of the head and that descriptions of these same views are preferentially utilised during recognition.

The effects of nurses changing from uniforms to everyday clothes on a psychiatric rehabilitation ward

There are few controlled studies investigating the effects of nurses changing from uniforms to everyday clothes. A quasi-experimental design was used where patient behaviour was measured before and after such a change and in which some degree of control was achieved by assessing the major sources of bias (i.e. medication, ward practices, etc.). The results suggest that the change in dress led to a decrease in deviant behaviour (particularly violent incidents) and patient estrangement and an increase in the number of nurses in whom patients could confide. These changes in behaviour appeared to be the result of changes in the nature of the relationships/interactions between patients and staff brought about by the change in nurse dress.

Improving the quality of care on psychiatric hospital rehabilitation wards. A controlled evaluation

This study attempted to use feedback from the Model Standards Questionnaires (a series designed to measure the quality of care) to improve care on a psychiatric hospital's rehabilitation wards. Both a controlled and quasi-experimental design were used. The controlled design provided evidence that feedback from the Questionnaire concerned with the Individual Programmes of Treatment and Care led to improvements in these practices but not for the remaining three questionnaires. The quasi-experimental design indicated that the significant generalised improvement in care, over all questionnaires, was most likely due to the feedback.

Gaze patterns of mentally retarded adults in two contrasting environments

Two matched samples of mentally retarded adults were video recorded on two occasions, before and after one group was transferred to a different type of hospital, and their gaze patterns analyzed. Overall, only slight changes after transfer were found, but analysis according to amount of looking at the interviewer on the first occasion showed that those transferred subjects who initially looked little of the time significantly increased their amount of looking after transfer. Some correlations with the Adaptive Behavior Scale were also reported.
