Cost-effectiveness of therapist-assisted internet-delivered psychological therapies for PTSD differing in trauma focus in England: an economic evaluation based on the STOP-PTSD trial.

BACKGROUND: Although there are effective psychological treatments for post-traumatic stress disorder (PTSD), they remain inaccessible for many people. Digitally enabled therapy is a way to overcome this problem; however, there is little evidence on which forms of these therapies are most cost effective in PTSD. We aimed to assess the cost-effectiveness of the STOP-PTSD trial, which evaluated two therapist-assisted, internet-delivered cognitive behavioural therapies: cognitive therapy for PTSD (iCT-PTSD) and a programme focusing on stress management (iStress-PTSD). METHODS: In this health economic evaluation, we used data from the STOP-PTSD trial (n=217), a single-blind, randomised controlled trial, to compare iCT-PTSD and iStress-PTSD in terms of resource use and health outcomes. In the trial, participants (aged ≥18 years) who met DSM-5 criteria for PTSD were recruited from primary care therapy services in South East England. The interventions were delivered online with therapist support for the first 12 weeks, and three telephone calls over the next 3 months. Participants completed questionnaires on symptoms, wellbeing, quality of life, and resource use at baseline, 13 weeks, 26 weeks, and 39 weeks after randomisation. We used a cost-effectiveness analysis to assess cost per quality-adjusted life year (QALY) at 39 weeks post-randomisation, from the perspective of the English National Health Service (NHS) and personal social services and on the basis of intention-to-treat for complete cases. Treatment modules and the platform design were developed with extensive input from service users: service users also advised on the trial protocol and methods, including the health economic measures. This is a pre-planned analysis of the STOP-PTSD trial; the trial was registered prospectively on the ISRCTN Registry (ISRCTN16806208). FINDINGS: NHS costs were similar across treatment groups, but clinical outcomes were superior for iCT-PTSD compared with iStress-PTSD. The incremental cost-effectiveness ratio for NHS costs and personal social services was estimated as £1921 per QALY. iCT-PTSD had an estimated 91·6% chance of being cost effective at the £20 000 per QALY threshold. From the societal perspective, iCT-PTSD was cost saving compared with iStress-PTSD. INTERPRETATION: iCT-PTSD is a cost-effective form of therapist-assisted, internet-delivered psychological therapy relative to iStress-PTSD, and it could be considered for clinical implementation.

Cognitive behavioural therapy for social anxiety disorder in people with bipolar disorder: a case series.

BACKGROUND: Social anxiety disorder increases the likelihood of unfavourable outcomes in people with bipolar disorder. Cognitive behavioural therapy (CBT) is the first-line treatment for social anxiety disorder. However, people with bipolar disorder have been excluded from the studies that this recommendation is based on.  METHOD: We completed a case series to obtain initial data on whether CBT is an acceptable, safe, and effective treatment for social anxiety disorder in people with bipolar disorder. RESULTS: Eleven euthymic participants with bipolar disorder attended up to sixteen treatment and three follow-up sessions of CBT for social anxiety disorder. Participants attended on average 95% of the offered CBT sessions. No adverse events were reported. Participants' mean score on the Social Phobia Inventory decreased from 46.5 (SD 6.6) before the treatment to 19.8 (SD 11.9) at the end of the sixteen-session intervention and further to 15.8 (SD 10.3) by the end of the 3-month follow-up. This degree of improvement is equivalent to the effect observed in studies of CBT for social anxiety disorder in people without severe mental illness. CONCLUSIONS: This case series provides preliminary evidence that CBT is acceptable, safe, and effective for treating social anxiety disorder in people with bipolar disorder during euthymia. A randomized controlled trial is needed to confirm these findings, and to establish whether treatment for social anxiety disorder improves the course of bipolar disorder.

Changes in cognitive processes and coping strategies precede changes in symptoms during cognitive therapy for posttraumatic stress disorder.

Theories of posttraumatic stress disorder (PTSD) highlight the role of cognitive and behavioral factors in its development, maintenance, and treatment. This study investigated the relationship between changes in factors specified in Ehlers and Clark's (2000) model of PTSD and PTSD symptom change in 217 patients with PTSD who were treated with cognitive therapy for PTSD (CT-PTSD) in routine clinical care. Bivariate latent change score models (LCSM) of session-by-session changes in self-report measures showed that changes in PTSD symptoms were preceded by changes in negative appraisals, flashback characteristics of unwanted memories, safety behaviours, and unhelpful responses to intrusions, but not vice versa. For changes in trauma memory disorganization and PTSD symptoms we found a bidirectional association. This study provides evidence that cognitive and behavioral processes proposed in theoretical models of PTSD play a key role in driving symptom improvement during CT-PTSD.

Therapist-assisted online psychological therapies differing in trauma focus for post-traumatic stress disorder (STOP-PTSD): a UK-based, single-blind, randomised controlled trial.

BACKGROUND: Many patients are currently unable to access psychological treatments for post-traumatic stress disorder (PTSD), and it is unclear which types of therapist-assisted internet-based treatments work best. We aimed to investigate whether a novel internet-delivered cognitive therapy for PTSD (iCT-PTSD), which implements all procedures of a first-line, trauma-focused intervention recommended by the UK National Institute for Health and Care Excellence (NICE) for PTSD, is superior to internet-delivered stress management therapy for PTSD (iStress-PTSD), a comprehensive cognitive behavioural treatment programme focusing on a wide range of coping skills. METHODS: We did a single-blind, randomised controlled trial in three locations in the UK. Participants (≥18 years) were recruited from UK National Health Service (NHS) Improving Access to Psychological Therapies (IAPT) services or by self-referral and met DSM-5 criteria for PTSD to single or multiple events. Participants were randomly allocated by a computer programme (3:3:1) to iCT-PTSD, iStress-PTSD, or a 3-month waiting list with usual NHS care, after which patients who still met PTSD criteria were randomly allocated (1:1) to iCT-PTSD or iStress-PTSD. Randomisation was stratified by location, duration of PTSD (<18 months or ≥18 months), and severity of PTSD symptoms (high vs low). iCT-PTSD and iStress-PTSD were delivered online with therapist support by messages and short weekly phone calls over the first 12 weeks (weekly treatment phase), and three phone calls over the next 3 months (booster phase). The primary outcome was the severity of PTSD symptoms at 13 weeks after random assignment, measured by self-report on the PTSD Checklist for DSM-5 (PCL-5), and analysed by intention-to-treat. Safety was assessed in all participants who started treatment. Process analyses investigated acceptability and compliance with treatment, and candidate moderators and mediators of outcome. The trial was prospectively registered with the ISRCTN registry, ISRCTN16806208. FINDINGS: Of the 217 participants, 158 (73%) self-reported as female, 57 (26%) as male, and two (1%) as other; 170 (78%) were White British, 20 (9%) were other White, six (3%) were Asian, ten (5%) were Black, eight (4%) had a mixed ethnic background, and three (1%) had other ethnic backgrounds. Mean age was 36·36 years (SD 12·11; range 18-71 years). 52 (24%) participants met self-reported criteria for ICD-11 complex PTSD. Fewer than 10% of participants dropped out of each treatment group. iCT-PTSD was superior to iStress-PTSD in reducing PTSD symptoms, showing an adjusted difference on the PCL-5 of -4·92 (95% CI -8·92 to -0·92; p=0·016; standardised effect size d=0·38 [0·07 to 0·69]) for immediate allocations and -5·82 (-9·59 to -2·04; p=0·0027; d=0·44 [0·15 to 0·72]) for all treatment allocations. Both treatments were superior to the waiting list for PCL-5 at 13 weeks (d=1·67 [1·23 to 2·10] for iCT-PTSD and 1·29 [0·85 to 1·72] for iStress-PTSD). The advantages in outcome for iCT-PTSD were greater for participants with high dissociation or complex PTSD symptoms, and mediation analyses showed both treatments worked by changing negative meanings of the trauma, unhelpful coping, and flashback memories. No serious adverse events were reported. INTERPRETATION: Trauma-focused iCT-PTSD is effective and acceptable to patients with PTSD, and superior to a non-trauma-focused cognitive behavioural stress management therapy, suggesting that iCT-PTSD is an effective way of delivering the contents of CT-PTSD, one of the NICE-recommended first-line treatments for PTSD, while reducing therapist time compared with face-to-face therapy.

Video feedback to update negative self-perceptions in social anxiety disorder: A comparison of internet-delivered vs face-to-face cognitive therapy formats.

BACKGROUND: Video feedback is a technique used in cognitive therapy for social anxiety disorder (CT-SAD) to update patients' negative self-perceptions of how they appear to others. Clients are supported to watch video of themselves engaging in social interactions. While typically undertaken in session with a therapist, this study aimed to investigate the effectiveness of remotely delivered video feedback embedded within an Internet-based cognitive therapy program (iCT-SAD). METHODS: We examined patients' self-perceptions and social anxiety symptoms before and after video feedback in two randomised controlled trials. Study 1 compared 49 iCT-SAD participants with 47 from face-to-face CT-SAD. Study 2 was a replication using data from 38 iCT-SAD participants from Hong Kong. RESULTS: In Study 1, ratings of self-perceptions and social anxiety showed significant reductions following video feedback, in both treatment formats. 92 % of participants in iCT-SAD, and 96 % in CT-SAD thought they looked less anxious compared to their predictions after viewing the videos. The change in self-perception ratings was larger in CT-SAD compared to iCT-SAD, but there was no evidence that the impact of video feedback on social anxiety symptoms around a week later differed between the two treatments. Study 2 replicated the iCT-SAD findings of Study 1. LIMITATIONS: The level of therapist support in iCT-SAD videofeedback varied with clinical need and was not measured. CONCLUSIONS: The findings indicate that video feedback can be delivered effectively online, and that its impact on social anxiety is not significantly different from in-person treatment delivery.

More than doubling the clinical benefit of each hour of therapist time: a randomised controlled trial of internet cognitive therapy for social anxiety disorder.

BACKGROUND: Cognitive therapy for social anxiety disorder (CT-SAD) is recommended by NICE (2013) as a first-line intervention. Take up in routine services is limited by the need for up to 14 ninety-min face-to-face sessions, some of which are out of the office. An internet-based version of the treatment (iCT-SAD) with remote therapist support may achieve similar outcomes with less therapist time. METHODS: 102 patients with social anxiety disorder were randomised to iCT-SAD, CT-SAD, or waitlist (WAIT) control, each for 14 weeks. WAIT patients were randomised to the treatments after wait. Assessments were at pre-treatment/wait, midtreatment/wait, posttreatment/wait, and follow-ups 3 & 12 months after treatment. The pre-registered (ISRCTN 95 458 747) primary outcome was the social anxiety disorder composite, which combines 6 independent assessor and patient self-report scales of social anxiety. Secondary outcomes included disability, general anxiety, depression and a behaviour test. RESULTS: CT-SAD and iCT-SAD were both superior to WAIT on all measures. iCT-SAD did not differ from CT-SAD on the primary outcome at post-treatment or follow-up. Total therapist time in iCT-SAD was 6.45 h. CT-SAD required 15.8 h for the same reduction in social anxiety. Mediation analysis indicated that change in process variables specified in cognitive models accounted for 60% of the improvements associated with either treatment. Unlike the primary outcome, there was a significant but small difference in favour of CT-SAD on the behaviour test. CONCLUSIONS: When compared to conventional face-to-face therapy, iCT-SAD can more than double the amount of symptom change associated with each therapist hour.

What do others think? The why, when and how of using surveys in CBT.

Surveys are a powerful technique in cognitive behavioural therapy (CBT). A form of behavioural experiment, surveys can be used to test beliefs, normalise symptoms and experiences, and generate compassionate perspectives. In this article, we discuss why and when to use surveys in CBT interventions for a range of psychological disorders. We also present a step-by-step guide to collaboratively designing surveys with patients, selecting the appropriate recipients, sending out surveys, discussing responses and using key learning as a part of therapy. In doing so, we hope to demonstrate that surveys are a flexible, impactful, time-efficient, individualised technique which can be readily and effectively integrated into CBT interventions.

Ten misconceptions about trauma-focused CBT for PTSD.

Therapist cognitions about trauma-focused psychological therapies can affect our implementation of evidence-based therapies for posttraumatic stress disorder (PTSD), potentially reducing their effectiveness. Based on observations gleaned from teaching and supervising one of these treatments, cognitive therapy for PTSD (CT-PTSD), ten common 'misconceptions' were identified. These included misconceptions about the suitability of the treatment for some types of trauma and/or emotions, the need for stabilisation prior to memory work, the danger of 'retraumatising' patients with memory-focused work, the risks of using memory-focused techniques with patients who dissociate, the remote use of trauma-focused techniques, and the perception of trauma-focused CBT as inflexible. In this article, these misconceptions are analysed in light of existing evidence and guidance is provided on using trauma-focused CT-PTSD with a broad range of presentations.

'I'm unlikeable, boring, weird, foolish, inferior, inadequate': how to address the persistent negative self-evaluations that are central to social anxiety disorder with cognitive therapy.

Patients with social anxiety disorder (SAD) have a range of negative thoughts and beliefs about how they think they come across to others. These include specific fears about doing or saying something that will be judged negatively (e.g. 'I'll babble', 'I'll have nothing to say', 'I'll blush', 'I'll sweat', 'I'll shake', etc.) and more persistent negative self-evaluative beliefs such as 'I am unlikeable', 'I am foolish', 'I am inadequate', 'I am inferior', 'I am weird/different' and 'I am boring'. Some therapists may take the presence of such persistent negative self-evaluations as being a separate problem of 'low self-esteem', rather than seeing them as a core feature of SAD. This may lead to a delay in addressing the persistent negative self-evaluations until the last stages of treatment, as might be typically done in cognitive therapy for depression. It might also prompt therapist drift from the core interventions of NICE recommended cognitive therapy for social anxiety disorder (CT-SAD). Therapists may be tempted to devote considerable time to interventions for 'low self-esteem'. Our experience from almost 30 years of treating SAD within the framework of the Clark and Wells (1995) model is that when these digressions are at the cost of core CT-SAD techniques, they have limited value. This article clarifies the role of persistent negative self-evaluations in SAD and shows how these beliefs can be more helpfully addressed from the start, and throughout the course of CT-SAD, using a range of experiential techniques. Key learning aims: To recognise persistent negative self-evaluations as a key feature of SAD.To understand that persistent negative self-evaluations are central in the Clark and Wells (1995) cognitive model and how to formulate these as part of SAD.To be able to use all the experiential interventions in cognitive therapy for SAD to address these beliefs.

Belief in Protecting Others and Social Perceptions of Face Mask Wearing Were Associated With Frequent Mask Use in the Early Stages of the COVID Pandemic in the UK.

Face masks are now seen as a key tool in the world's recovery from the COVID-19 pandemic. However, during the early stages of the outbreak, face mask use in the United Kingdom (UK) was significantly lower than that of countries equally impacted by the virus. We were interested to explore whether social cognitions played a role in levels of mask wearing. A cross-sectional online survey of UK adults (n=908) was conducted in July 2020. Estimated face mask use and thoughts about wearing face masks were assessed using measures developed for this study. Participants also answered questions about their general mood, social anxiety and basic demographic data. Multiple regression was used to examine factors associated with mask wearing. Participants' estimated mask wearing was low when in public spaces, such as the park (17%) or walking on the high street (36%). However, broadly fitting with UK guidance at the time, rates were considerably higher when in situations of closer proximity to others, such as on public transport (94%), in a shop or café (62%), when speaking to somebody in an enclosed public space (67%) or in a busy area when social distancing was not possible (79%). When looking at estimated mask wearing when in proximity to others, positive social cognitions (e.g., I'll look confident and competent wearing a mask) were associated with more wearing, whereas negative social cognitions (e.g., I'll look anxious, I'll look foolish) were associated with less wearing. These results remained after controlling for factors that have indicated increased risk from COVID-19 (age, gender, ethnicity, presence of a health condition or pregnancy), belief about the health benefit for others and levels of depression and social anxiety. The largest predictors of mask wearing were the amount of people believed wearing a mask would keep others safe and the presence of an underlying health condition. The study findings indicate that future public health campaigns would benefit from a focus on strengthening beliefs about the protective benefits of masks, but also promoting positive social messages about wearing in public (e.g., mask wearing means you are confident and competent).

The Relationship Between Working Alliance and Symptom Improvement in Cognitive Therapy for Posttraumatic Stress Disorder.

Background: Working alliance has been shown to predict outcome of psychological treatments in multiple studies. Conversely, changes in outcome scores have also been found to predict working alliance ratings. Objective: To assess the temporal relationships between working alliance and outcome in 230 patients receiving trauma-focused cognitive behavioral treatment for posttraumatic stress disorder (PTSD). Methods: Ratings of working alliance were made by both the patient and therapist after sessions 1, 3, and 5 of a course of Cognitive Therapy for PTSD (CT-PTSD). Autoregressive, cross-lagged panel models were used to examine whether working alliance predicted PTSD symptom severity at the next assessment point and vice versa. Linear regressions tested the relationship between alliance and treatment outcome. Results: Both patients' and therapists' working alliance ratings after session 1 predicted PTSD symptom scores at the end of treatment, controlling for baseline scores. At each assessment point, higher therapist working alliance was associated with lower PTSD symptoms. Crossed-lagged associations were found for therapist-rated alliance, but not for patient-rated alliance: higher therapists' alliance ratings predicted lower PTSD symptom scores at the next assessment point. Similarly, lower PTSD symptoms predicted higher therapist working alliance ratings at the next assessment point. Ruminative thinking was negatively related to therapists' alliance ratings. Conclusions: Working alliance at the start of treatment predicted treatment outcome in patients receiving CT-PTSD and may be an important factor in setting the necessary conditions for effective treatment. For therapists, there was a reciprocal relationship between working alliance and PTSD symptom change in their patients during treatment, suggesting that their alliance ratings predicted symptom change, but were also influenced by patients' symptom change.

Cognitive therapy compared with CBT for social anxiety disorder in adolescents: a feasibility study.

BACKGROUND: Social anxiety disorder (SAD) is common, typically starts in adolescence and has a low natural recovery rate. Existing psychological treatments for adolescent SAD are only moderately effective. It is possible that recovery rates for adolescents could be substantially improved by adapting a psychological therapy that is highly effective among adults with SAD. OBJECTIVES: To train child and adolescent mental health services (CAMHS) therapists to deliver cognitive therapy for SAD in adolescents (CT-SAD-A) and assess therapist competence. To estimate the costs to the NHS of training therapists to deliver CT-SAD-A and the mean cost per adolescent treated. To examine the feasibility of a randomised controlled trial (RCT) to compare CT-SAD-A with the general form of cognitive-behavioural therapy that is more commonly used. DESIGN: During the training phase of the study, it became clear that the RCT would not be feasible because of high staff turnover and unfilled posts within CAMHS and changes in the nature of referrals, which meant that few young people with primary SAD were accessing some of the participating services. The study design was altered to comprise the following: a training case series of CT-SAD-A delivered in routine CAMHS, an estimate of the cost to the NHS of training therapists to deliver CT-SAD-A and of the mean cost per adolescent treated, and qualitative interviews with participating young people, parents, therapists and service managers/leads. SETTING: Five CAMHS teams within Berkshire Healthcare and Oxford Health NHS Foundation Trusts. PARTICIPANTS: Eight therapists received training in CT-SAD-A. Twelve young people received CT-SAD-A, delivered by six therapists. Six young people, six parents, seven therapists and three managers participated in qualitative interviews. INTERVENTIONS: Cognitive therapy for social anxiety disorder in adolescents (CT-SAD-A). MAIN OUTCOME MEASURES: Measured outcomes included social anxiety symptoms and diagnostic status, comorbid symptoms of anxiety and depression, social and general functioning, concentration in class and treatment acceptability. Patient level utilisation of the intervention was collected using clinicians' logs. RESULTS: Nine out of 12 participants achieved good outcomes across measures (r ≥ 0.60 across social anxiety measures). The estimated cost of delivering CT-SAD-A was £1861 (standard deviation £358) per person. Qualitative interviews indicated that the treatment was acceptable to young people, parents and therapists, but therapists and managers experienced challenges when implementing the training and treatment within the current CAMHS context. LIMITATIONS: Findings were based on a small, homogeneous sample and there was no comparison arm. CONCLUSIONS: CT-SAD-A is a promising treatment for young people with SAD, but the current CAMHS context presents challenges for its implementation. FUTURE WORK: Further work is needed to ensure that CAMHS can incorporate and test CT-SAD-A. Alternatively, CT-SAD-A should be delivered and tested in other settings that are better configured to treat young people whose lives are held back by SAD. The new schools Mental Health Support Teams envisaged in the 2017 Children's Mental Health Green Paper may provide such an opportunity. FUNDING: The National Institute for Health Research (NIHR) Health Technology Assessment programme. Individual funding was also provided for Cathy Creswell, David M Clark and Eleanor Leigh as follows: NIHR Research Professorship (Cathy Creswell); Wellcome Senior Investigator Award (Anke Ehlers and David M Clark); and the Wellcome Clinical Research Training Fellowship (Eleanor Leigh).

WHY DID WE DO THIS STUDY?: People with social anxiety disorder (SAD) are scared of social situations because they fear embarrassment or humiliation. SAD usually starts at around 13 years of age, typically does not go away without treatment, and leads to personal and social difficulties. Clark and Wells' cognitive therapy for SAD in adults (CT-SAD) is a talking therapy that produces excellent outcomes. CT-SAD has not previously been adapted for or tested with adolescents. WHAT DID WE DO?: We adapted CT-SAD so that it was suitable for adolescents (CT-SAD-A). We intended to compare this with current practice in child and adolescent mental health services (CAMHS). However, we were not able to complete the trial owing to a high staff turnover and a lack of young people with SAD coming into CAMHS. Instead, we examined outcomes for young people who received CT-SAD-A during the therapist training phase and explored the views of young people, their parents, the therapists and CAMHS managers about CT-SAD-A and the study. WHAT DID WE FIND?: Young people's outcomes were very promising; for example, 10 out of 12 participants reported a reliable improvement in social anxiety. The young people and their parents were generally positive about the treatment. Therapists were also positive about the treatment, but they and their managers found it difficult to implement the treatment within their CAMHS teams. The cost to the NHS to treat young people with SAD within this study compared favourably with the cost of treating adults. WHAT DOES THIS MEAN?: We need to be careful about drawing conclusions from a small sample size, but we suggest that further work is needed to ensure that CT-SAD-A can be delivered and tested in CAMHS. Alternatively, CT-SAD-A should be delivered and tested in community or school settings that can treat young people whose lives are held back by SAD.

Delivering cognitive therapy for adolescent social anxiety disorder in NHS CAMHS: a clinical and cost analysis.

BACKGROUND: Cognitive therapy, based on the Clark and Wells (1995) model, is a first-line treatment for adults with social anxiety disorder (SAD), and findings from research settings suggest it has promise for use with adolescents (Cognitive Therapy for Social Anxiety Disorder in Adolescents; CT-SAD-A). However, for the treatment to be suitable for delivery in routine clinical care, two questions need to be addressed. AIMS: Can therapists be trained to achieve good outcomes in routine Child and Adolescent Mental Health Services (CAMHS), and what are the costs associated with training and treatment? METHOD: CAMHS therapists working in two NHS trusts received training in CT-SAD-A. They delivered the treatment to adolescents with SAD during a period of supervised practice. We examined the clinical outcomes for the 12 patients treated during this period, and estimated costs associated with treatment and training. RESULTS: Treatment produced significant improvements in social anxiety symptoms, general anxiety and depression symptoms, and reductions in putative process measures. Seventy-five per cent (9 out of 12) patients showed a reliable and clinically significant improvement in social anxiety symptoms, and 64% (7/11) lost their primary diagnosis of SAD. The total cost to the NHS of the CT-SAD-A treatment was £4047 (SD = £1003) per adolescent treated, of which £1861 (SD = £358) referred to the specific estimated cost of face-to-face delivery; the remaining cost was for training and supervising therapists who were not previously familiar with the treatment. CONCLUSIONS: This study provides preliminary evidence that clinicians can deliver good patient outcomes for adolescents with SAD in routine CAMHS during a period of supervised practice after receiving a 2-day training workshop. Furthermore, the cost of delivering CT-SAD-A with adolescents appeared to be no more than the cost of delivering CT-SAD with adults.

'I was treated like dirt': evaluating links between betrayal and mental contamination in clinical samples.

BACKGROUND: Little is known about the impact of interpersonal betrayal experiences on mental health. Research suggests a link between betrayal and mental contamination (MC) within some forms of obsessive compulsive disorder (OCD). This study represents an initial exploration of that link in clinical samples. AIMS: A measure for assessing perceptions of betrayal was developed and evaluated (Study 1) in order to assess the extent of specificity of any association between the impact of betrayal and MC, and to estimate the extent of the impact of betrayal across common psychological disorders (Study 2). METHOD: In Study 1, the Perception of Betrayal Scale (POBS) was completed by 217 community participants; an exploratory principal components analysis identified the dimensional structure of the POBS. Study 2 was based on a cross-sectional, between-groups design, with three clinical groups [OCD (n = 23), other anxiety disorders (n = 21) and depression (n = 18)] and a non-clinical control group (n = 21). Three clinical groups (OCD, other anxiety disorders, and depression) and a community group completed a selection of measures via questionnaire. RESULTS: In Study 1, the POBS was found to have an internal consistency of α = .95, and four factors were identified: preoccupation with betrayal events, belief that betrayal had caused major life change, lack of trust due to betrayal and betrayal leading to traumatic responses. In Study 2, the OCD group scored more highly in terms of maladaptive perceptions of betrayal than the other groups. Regression analysis showed betrayal scores to be a moderate predictor of the experience of MC; the POBS subscales lack of trust due to betrayal and betrayal leading to traumatic responses were found to be significantly associated with MC. Although there was some overlap with bitterness, betrayal better predicted MC. CONCLUSION: Findings support the hypothesis of a specific relationship between the construct of betrayal and MC.

Treating posttraumatic stress disorder remotely with cognitive therapy for PTSD.

Delivering trauma-focused cognitive behavioural therapy to patients with PTSD during the COVID-19 pandemic poses challenges. The therapist cannot meet with the patient in person to guide them through trauma-focused work and other treatment components, and patients are restricted in carrying out treatment-related activities and behavioural experiments that involve contact with other people. Whilst online trauma-focused CBT treatments for PTSD have been developed, which overcome some of these barriers in that they can be delivered remotely, they are not yet routinely available in clinical services in countries, such as the UK. Cognitive therapy for PTSD (CT-PTSD) is a trauma-focused cognitive behavioural therapy that is acceptable to patients, leads to high rates of recovery and is recommended as a first-line treatment for the disorder by international clinical practice guidelines. Here we describe how to deliver CT-PTSD remotely so that patients presenting with PTSD during the COVID-19 pandemic can still benefit from this evidence-based treatment.

Brindar terapia cognitivo conductual (TCC) centrada en el trauma a pacientes con Trastorno de Estrés Postraumático (TEPT) durante la pandemia de COVID-19 plantea desafíos. El terapeuta no puede reunirse con el paciente en persona para guiarlo a través del trabajo centrado en el trauma y apoyarlo con otros componentes del tratamiento; y por otra parte, los pacientes tienen restricciones para llevar a cabo las actividades relacionadas con el tratamiento y los experimentos de comportamiento que impliquen contacto con otras personas. Si bien se han desarrollado tratamientos de TCC centrados en el trauma en línea para el TEPT, que superan algunas de estas barreras en el sentido de que pueden administrarse de forma remota, todavía no están disponibles de forma rutinaria en los servicios clínicos de los países, como en el Reino Unido. La terapia cognitiva para el TEPT (TC-TEPT) es una terapia cognitiva conductual centrada en el trauma que es aceptable para los pacientes, conduce a altas tasas de recuperación y se recomienda como tratamiento de primera línea para el trastorno según las pautas internacionales de práctica clínica (APA, 2017; International Society of Traumatic Stress Studies, 2019; National Institute of Health and Clinical Excellence, 2018). Aquí describimos cómo administrar TC-TEPT de forma remota para que los pacientes que se presentan con TEPT durante la pandemia de COVID-19 aún puedan beneficiarse de este tratamiento basado en la evidencia.

Respiratory failure in a cancer patient: pulmonary thrombotic microangiopathy.

The hypoxic patient with a normal chest X-ray can be a diagnostic challenge. This case illustrates the rational diagnostic process and describes a relatively rare but important complication of cancer metastasis. Thrombotic microangiopathy, like lymphangitis carcinomatosa, may cause respiratory failure and is a poor prognostic finding. However, unlike lymphangitis carcinomatosa, it may not have specific findings on cross-sectional imaging.

A randomised controlled trial of therapist-assisted online psychological therapies for posttraumatic stress disorder (STOP-PTSD): trial protocol.

BACKGROUND: Over the last few decades, effective psychological treatments for posttraumatic stress disorder (PTSD) have been developed, but many patients are currently unable to access these treatments. There is initial evidence that therapist-assisted internet-based psychological treatments are effective for PTSD and may help increase access, but it remains unclear which of these treatments work best and are most acceptable to patients. This randomised controlled trial will compare a trauma-focussed and a nontrauma-focussed therapist-assisted cognitive behavioural Internet treatment for PTSD: Internet-delivered cognitive therapy for PTSD (iCT-PTSD) and internet-delivered stress management therapy (iStress-PTSD). METHODS/DESIGN: The study is a single-blind, randomised controlled trial comparing iCT-PTSD, iStress-PTSD and a 13-week wait-list condition, with an embedded process study. Assessors of treatment outcome will be blinded to trial arm. Two hundred and seventeen participants who meet DSM-5 criteria for PTSD will be randomly allocated by a computer programme to iCT-PTSD, iStress-PTSD or wait-list at a 3:3:1 ratio. The primary assessment point is at 13 weeks, and further assessments are taken at 6, 26, 39 and 65 weeks. The primary outcome measure is the severity of PTSD symptoms as measured by the PTSD Checklist for DSM-5 (PCL-5). Secondary measures of PTSD symptoms are the Clinician Administered PTSD Scale for DSM-5 (CAPS-5) and the Impact of Event Scale-Revised (IES-R). Other symptoms and well-being will be assessed with the Patient Health Questionnaire (PHQ-9), Generalised Anxiety Disorder Scale (GAD-7), WHO (Five) Well-Being Index, Work and Social Adjustment Scale (WSAS), Endicott Quality of Life Scale (QoL), and Insomnia Sleep Index (ISI). Health economics analyses will consider quality of life, productivity, health resource utilisation, employment status and state benefits, and treatment delivery costs. Process analyses will investigate candidate mediators and moderators of outcome. Patient experience will be assessed by interview and questionnaire. DISCUSSION: This study will be the first to compare the efficacy of a trauma-focussed and nontrauma-focussed therapist-assisted online cognitive behavioural treatment for people with posttraumatic stress disorder. TRIAL REGISTRATION: ISRCTN16806208. Registered prospectively on 5 January 2018.

Cognitive processes associated with sudden gains in cognitive therapy for posttraumatic stress disorder in routine care.

OBJECTIVE: Although most studies investigating sudden gains in treatments for posttraumatic stress disorder (PTSD) report a positive association between sudden gains and outcomes at the end of treatment, less is known about sudden gains in routine clinical care and the processes involved in their occurrence. This study investigated changes in cognitive factors (negative appraisals, trauma memory characteristics) before, during, and after sudden gains in PTSD symptom severity. METHOD: Two samples (N1 = 248, N2 = 234) of patients who received trauma-focused cognitive therapy for PTSD in routine clinical care were analyzed. Mahalanobis distance matching, including the propensity score, was used to compare patients with sudden gains and similar patients without sudden gains. Estimates from both samples were meta-analyzed to obtain pooled effects. RESULTS: Patients with sudden gains (n1 = 76, n2 = 87) reported better treatment outcomes in PTSD symptom severity, depression, and anxiety at the end of therapy and follow-up than those without sudden gains. No baseline predictors of sudden gains could be reliably identified. During sudden gains, those with sudden gains had greater changes in both cognitive factors than matched patients. Meta-analyses of the two samples showed that negative appraisals had already decreased in the session prior to sudden gains compared with matched patients. CONCLUSIONS: The pooled estimates suggest that changes in negative trauma-related appraisals precede sudden gains in PTSD symptoms. The results suggest that interventions that promote change in appraisals may also facilitate sudden gains in therapy. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Cognitive therapy for post-traumatic stress disorder following critical illness and intensive care unit admission.

Around a quarter of patients treated in intensive care units (ICUs) will develop symptoms of post-traumatic stress disorder (PTSD). Given the dramatic increase in ICU admissions during the COVID-19 pandemic, clinicians are likely to see a rise in post-ICU PTSD cases in the coming months. Post-ICU PTSD can present various challenges to clinicians, and no clinical guidelines have been published for delivering trauma-focused cognitive behavioural therapy with this population. In this article, we describe how to use cognitive therapy for PTSD (CT-PTSD), a first line treatment for PTSD recommended by the National Institute for Health and Care Excellence. Using clinical case examples, we outline the key techniques involved in CT-PTSD, and describe their application to treating patients with PTSD following ICU. KEY LEARNING AIMS: To recognise PTSD following admissions to intensive care units (ICUs).To understand how the ICU experience can lead to PTSD development.To understand how Ehlers and Clark's (2000) cognitive model of PTSD can be applied to post-ICU PTSD.To be able to apply cognitive therapy for PTSD to patients with post-ICU PTSD.

Treating social anxiety disorder remotely with cognitive therapy.

Remote delivery of evidence-based psychological therapies via video conference has become particularly relevant following the COVID-19 pandemic, and is likely to be an on-going method of treatment delivery post-COVID. Remotely delivered therapy could be of particular benefit for people with social anxiety disorder (SAD), who tend to avoid or delay seeking face-to-face therapy, often due to anxiety about travelling to appointments and meeting mental health professionals in person. Individual cognitive therapy for SAD (CT-SAD), based on the Clark and Wells (1995) model, is a highly effective treatment that is recommended as a first-line intervention in NICE guidance (NICE, 2013). All of the key features of face-to-face CT-SAD (including video feedback, attention training, behavioural experiments and memory-focused techniques) can be adapted for remote delivery. In this paper, we provide guidance for clinicians on how to deliver CT-SAD remotely, and suggest novel ways for therapists and patients to overcome the challenges of carrying out a range of behavioural experiments during remote treatment delivery. KEY LEARNING AIMS: To learn how to deliver all of the core interventions of CT-SAD remotely.To learn novel ways of carrying out behavioural experiments remotely when some in-person social situations might not be possible.
