Family-based treatment (FBT) has proven efficacy among adolescents with eating disorders (ED). However, it is not effective or suitable for all young people and their families, which makes alternative treatments important. This is the first pilot study to compare the relative effectiveness of manualised enhanced cognitive behaviour therapy (CBT-E) among a transdiagnostic eating disorder sample of adolescents for whom CBT-E was their first ED treatment (n=42), and a group who had previously started FBT which had been discontinued without full recovery (n=27). Participants (n=69) aged 13–17 with an eating disorder completed manualised CBT-E. Outcome measures included body mass index (BMI) centile, ED psychopathology and clinical impairment. Across the cohort, results showed improvements across ED psychopathology, clinical impairment and BMI centile. The effect of the intervention on ED psychopathology and clinical impairment did not vary between groups, nor did attrition rates. There was a difference between the groups on BMI centile, with those who had previously been treated with FBT showing no change in BMI centile, whereas those with no previous FBT increased BMI at post-treatment. Implications from this research suggest that CBT-E is a viable promising alternative and could be offered among those for whom FBT has not achieved full recovery.

1. (1) Delivering CBT-E to adolescents with eating disorders who have previously engaged in FBT but have not achieved full recovery is a promising subsequent treatment option.

2. (2) CBT-E was similarly completed and displayed similar overall group reductions in eating disorder symptoms in those who had discontinued FBT without full recovery compared with those who had not previously engaged with FBT.

3. (3) Results suggest that CBT-E could be offered when FBT has not achieved full recovery, although more research is required to understand optimal timings of treatment transition in such instances.

Despite high levels of depression and anxiety, there is relatively little attention to psychological treatment approaches to mental health issues for older adults living in nursing homes. Recent studies support the use of cognitive behaviour therapy (CBT) in this population and here we aim to highlight how CBT can be successfully adapted and implemented with beneficial results. The ELders AT Ease (ELATE) program is a unique service delivery model illustrating delivery of CBT with older adults living in nursing homes. The six modules forming the program, based on CBT, are described. A systems wide approach to delivery is emphasised and illustrated through two clinical case descriptions. Innovative mental health programs can have positive benefits for both residents and staff and support the use of CBT in this vulnerable and under-served client group.

Cognitive behavioural therapy (CBT) and eye-movement desensitisation and reprocessing (EMDR) are NICE-recommended evidence-based treatments for post-traumatic stress disorder (PTSD). However, there is less specification of which individuals might find CBT versus EMDR more effective, or whether other factors influence treatment outcomes. This study describes a service evaluation of trauma-focused CBT (CT-PTSD) and EMDR treatment outcomes for PTSD in a London out-patient NHS Talking Therapies (NHS TT) service over 11 years (N=1580). The evaluation was conducted in an adult sample (mean age 37 years), of which 65% were women. The mean number of treatment episodes for PTSD in the service in the sample was 2.39 (SD=1.86), and the mean number of therapy sessions attended was 6.15 (SD=6.43). When using NHS TT recovery criteria, there was no significant difference between PTSD recovery rates in the service for those who received CT-PTSD (40.8%) versus EMDR (43.6%). CT-PTSD was associated with greater reductions in anxious and depressive (but not PTSD-specific) symptoms than EMDR, but this was confounded by the fact that individuals receiving CT-PTSD in the service had higher anxiety and depression scores at start-of-treatment. Older age and non-female gender were associated with higher anxiety and depression scores. PTSD recovery rates were comparable to other NHS TT services. There is no clear indication that either CBT or EMDR is a more effective treatment for PTSD symptoms in the service, although preliminary findings could inform treatment planning regarding differential effects of the treatments on anxious and depressive symptoms. Other clinical implications are discussed.

Traumatic brain injury (TBI) can alter day-to-day life. While changes in cognition and physical function are most often cited, emotional disturbances, notably depression, are also common. For individuals who experience depression symptoms, mindfulness-based cognitive therapy (MBCT) may afford the opportunity to address these symptoms by teaching skills to mitigate negative thought patterns and foster acceptance. Yet, as with any treatment for depression, MBCT may not be the best fit for everyone. According to the literature, characteristics such as age, gender, and baseline mindfulness or pain levels have the potential to affect treatment response. While these factors have yet to be explored within a TBI sample, we must additionally consider whether possible cognitive impairment due to TBI plays a role in treatment response. Drawing from an earlier multi-site randomized controlled trial to explore the efficacy of MBCT for depression in a TBI sample, the current study examined the associations between a number of baseline factors (demographic, emotional, physical, and cognitive) and decreased depression scores post-intervention. Partial correlations adjusted for gender. Findings indicated that only higher levels of pain at baseline were associated with lesser effectiveness of the intervention. MBCT offers a good treatment option for most individuals experiencing depression following TBI.

The objectives of study 1 were to use expert opinion to identify the limitations of the Health Anxiety Inventory – Short Version (SHAI) for administration in medical populations and to develop an adapted version for medical populations. The objective of the second study was to evaluate the psychometric properties of the adapted measure. A three-round Delphi study method was used in study 1. Eight experts with experience of living with a physical health condition and four experts by profession working within physical health were invited to review the SHAI. Study 2 employed a cross-sectional mixed methods questionnaire design. Individuals with multiple sclerosis (n=115), myalgic encephalomyelitis/chronic fatigue syndrome (n=84) and chronic pain (n=116) were invited to complete a battery of questionnaires via an online survey. The adapted version of the SHAI for Medical Populations (HAI-M) consisted of 12 items scoring from 0 to 3, reaching high consensus (75% agreement) for administration in medical populations. All groups rated the HAI-M as more acceptable than the SHAI and no significant differences were found on HAI-M scores between clinical groups. The HAI-M demonstrated high internal consistency (.875), good test–retest reliability (.812) and convergent validity (.801). Divergent validity was also acceptable (.515). This study provides preliminary evidence for a psychometrically sound health anxiety screening tool for use in medical populations.

Economic variables such as socioeconomic status and debt are linked with an increased risk of a range of mental health problems and appear to increase the risk of developing of post-traumatic stress disorder (PTSD). Previous research has shown that people living in more deprived areas have more severe symptoms of depression and anxiety after treatment in England’s NHS Talking Therapies services. However, no research has examined if there is a relationship between neighbourhood deprivation and outcomes for PTSD specifically. This study was an audit of existing data from a single NHS Talking Therapies service. The postcodes of 138 service users who had received psychological therapy for PTSD were used to link data from the English Indices of Deprivation. This was analysed with the PCL-5 measure of PTSD symptoms pre- and post-treatment. There was no significant association between neighbourhood deprivation measures on risk of drop-out from therapy for PTSD, number of sessions received or PTSD symptom severity at the start of treatment. However, post-treatment PCL-5 scores were significantly more severe for those living in highly deprived neighbourhoods, with lower estimated income and greater health and disability. There was also a non-significant trend for the same pattern based on employment and crime rates. There was no impact of access to housing and services or living environment. Those living in more deprived neighbourhoods experienced less of a reduction in PTSD symptoms after treatment from NHS Talking Therapies services. Given the small sample size in a single city, this finding needs to be replicated with a larger sample.

1. (1) Previous literature has shown that socioeconomic deprivation increases the risk of a range of mental health problems.

2. (2) Existing research suggests that economic variables such as income and employment are associated with greater incidence of PTSD.

3. (3) In the current study, those living in more deprived areas experienced less of a reduction in PTSD symptoms following psychological therapy through NHS Talking Therapies.

4. (4) The relatively poorer treatment outcomes in the current study are not explained by differences in baseline PTSD severity or drop-out rates, which were not significantly different comparing patients from different socioeconomic strata.

Effective, evidence-based psychological therapies for prolonged grief reactions exist but are not routinely available in United Kingdom National Health Service (NHS) services. This audit evaluated the feasibility and clinical effectiveness of a high-intensity prolonged grief disorder therapy (PGDT) treatment pathway in an NHS Talking Therapies (NHS-TT) context for clients with a prolonged grief reaction alongside depression, anxiety and/or post-traumatic stress disorder. Seventeen experienced high-intensity therapists were trained to deliver PGDT. Ninety-one clients were treated between April 2022 and April 2024, 80 of whom met criteria and were included in this audit; 83% of clients completed at least four treatment sessions (a liberal estimate of minimum adequate dose), the mean number of sessions attended was 10.29 (SD=5.81) and rates of drop-out were low (16%). Data completeness rates were 100% depression, anxiety and functioning measures and 61% for the grief outcome (Brief Grief Questionnaire; BGQ). There was no evidence of treatment-related harms. There were statistically significant, large pre–post treatment effect size improvements across outcomes from intake to last treatment session (p<.001; Cohen’s d>1.05). According to NHS-TT outcome metrics for combined changes in anxiety and depression, 82% of clients exhibited reliable improvement, 72% showed recovery, and 68% of clients achieved reliable recovery. On the BGQ, rates of reliable improvement were 77% and rates of recovery were 63%. Effects held when focusing on the subgroup with more severe grief symptoms (intake BGQ≥8; n=40). These findings suggest it is feasible and probably effective to implement a PGDT pathway in an NHS-TT context.

Maladaptive daydreaming (MD) is an increasingly recognised mental health difficulty, which refers to a compulsive cycle of dissociative absorption in vivid mental fantasy that results in clinical distress and functional impairment. Fantasies are usually complex in plot and characters, and are highly pleasurable and absorbing. MD provides temporary escape, soothing, or attempted processing of difficult internal and external experiences, but results in longer-term negative consequences that both create and exacerbate real-life suffering. The literature thus far has expanded beyond defining and understanding MD and has turned its attention towards assessment and pilot interventions. This paper presents the first formulation framework and associated diagrammatic model of MD, drawing upon the existing evidence base and cognitive behavioural theory to capture its development, maintenance, and processes. The model was reviewed by two leading experts in the field and trialled by three contributors with lived experience of MD. Feedback was positive, suggesting it accurately captured and organised the complexity and depth of the MD experience, facilitated the development of personal insight, and fostered a sense of hope with regard to creating change. The model is intended for use within clinical practice to aid mental health professionals and people with MD to guide assessment, collaborative discovery and formulation, and intervention. It is imperative that the model be tested further within research and clinical practice to further ensure its efficacy, validity, and applicability for people with MD.

The last two decades have seen considerable development in our understanding of delusions, with medical perspectives broadening into more holistic bio-psychosocial models. Of particular relevance to services is the increasing evidence base for cognitive behavioural models and treatments. A number of national initiatives have aimed to ensure these developments are reflected in services. Primarily these have targeted adult services, yet delusions are no less common in older adults. Across two older adult services this study searched over 10,000 clinical notes to assess the number of individuals experiencing delusions, explored the perspectives of 27 staff members regarding their clinical approaches to working with delusions, and delivered a brief training on cognitive behavioural models and treatments of delusions. Three service users contributed to the training content. Endorsement of theoretical perspectives regarding delusions were measured pre- and post-training. Results showed over 20% of patients in the service may be experiencing paranoia or delusions, but only a handful were referred for CBT. Of 27 staff participants, less than half had received training on working with delusions, most of which was from as many as 20 years ago. Nearly all reported that a lack of knowledge prevented them from considering psychological perspectives. A quarter of staff across the two teams attended the training. No immediate changes in outcome measures were seen immediately post-training, with a striking diversity in approach reported by different members of staff. All staff qualitatively reported finding the training valuable, although engagement was dampened by high levels of stress and burnout.

2. (2) To understand the need for this growing evidence base to be reflected in services, including older adult services, not only in structured interventions offered by psychological therapists, but also in patient interactions and care planning by all professions working in multi-disciplinary teams.

Smartphone apps combined with psychological interventions may be beneficial for increasing adherence to treatment tasks and augmenting outcomes. Yet, there is limited research on the acceptability and feasibility of adjunctive smartphone apps with psychological therapies for adolescents engaging in self-harm and suicidal behaviours. This study aimed to evaluate the acceptability and feasibility of integrating the Dialectical Behaviour Therapy (DBT) Coach app as an adjunct to a comprehensive DBT programme. The study also aimed to explore statistical trends of the potential relationship between the DBT Coach app and symptom reduction, including self-harm, borderline personality disorder symptoms, emotion dysregulation, and DBT skill use, to inform future study design. A mixed-method design was used to evaluate the acceptability and feasibility of the app and clinician’s portal from the perspective of adolescent and clinician participants. Thematic analysis was used to analyse qualitative data. Results indicated varied experiences of acceptability and feasibility of the DBT Coach app and portal as an adjunct to DBT. Thematic analysis generated four over-arching themes and ten subthemes. The regression analysis provided statistical trends regarding potential relationships between app use and clinical outcomes, which would be helpful to explore in future research. Findings suggest that the app and portal were acceptable and feasible for the most part, with some barriers and challenges identified. Implications of this study are discussed.

Drug and alcohol users have been suggested to face disproportionate exclusion from mental health services, but data on any such exclusion are not readily available. This study examined the clinical records of those excluded from an NHS Talking Therapies service due to drug or alcohol use, focusing on (1) quantitative levels of alcohol consumption, and (2) the rationales documented by clinicians for excluding these individuals. Our results suggest that over half (57%) of those excluded due to alcohol use were consuming below the 15-unit daily threshold recommended for signposting to specialist alcohol assessment. Clinicians cited various rationales for exclusion, including the potential for poor treatment outcomes and health risks associated with concurrent use. Due to being based on a single service, these findings may be limited in their generalisability, but they offer an initial signal that there is potential over-exclusion of some alcohol users from NHS Talking Therapies, and that rationales for exclusion may not consistently align with best practice principles. We discuss implications for NHS Talking Therapies clinicians, and for the development of future clinical guidance.

5. (5) To explore how integrated working between NHS Talking Therapies and local drug and alcohol services can enhance service-user experiences.

The notion of cognitive detachment (i.e. the capacity to treat thoughts as just thoughts, with no greater significance or importance) is introduced in this paper. Its link to similar established terminologies (e.g. distancing, decentering, defusion/deliteralisation, detached mindfulness), importance within cognitive behaviour therapies and place within an adapted cognitive-behavioural framework is highlighted. The use of metaphor to facilitate cognitive detachment is then the primary focus of the paper. An overview of how metaphor has typically been used within psychotherapy is presented and reflects mostly the use of therapist-generated metaphor for psychoeducational purposes. While the use of metaphor in serving a therapeutic cognitive detachment function is not new, developing idiosyncratic client-generated metaphors in this regard has been largely neglected, despite the widely held view that client-generated metaphors are more potent. Practical guidance on how clinicians can collaboratively assist clients to intentionally generate their own personalised cognitive detachment metaphor is provided, and specific ways to elaborate metaphors during therapy to enhance metaphor application and hence effectiveness in enabling cognitive detachment is considered. Finally, clinical examples are provided to illustrate the varied, creative and rich metaphors that can emerge from this process.

This study described the development and assessment of the psychometric properties of the Dissociation-Integration of Self-States Scale (D-ISS). This is a new scale to assess dissociation at the ‘between modes’ or self-state (personality) level. The D-ISS is rooted in cognitive behavioural theory and designed to measure between-mode dissociation (dissociation between self-states) in clinical practice and research.

Study 1: D-ISS scale items were generated and then answered by 344 young adults (16–25 years) who reported experiencing stressful times. An exploratory factor analysis (EFA) was conducted and the results were used to refine the scale to 25 items.

Study 2: The final 25-item D-ISS was completed by 383 adults (18–65 years) who reported experiencing mental health difficulties. A confirmatory factor analysis (CFA) was conducted using the second dataset. Internal consistency, test–retest reliability, convergent validity and divergent validity of the final D-ISS was assessed.

Study 1: The EFA showed a clear 5-factor solution, which was used to refine the D-ISS to a total of 25 items with five items in each factor.

Study 2: The 5-factor solution from Study 1 was confirmed as a good fit by the CFA using the data collected in Study 2. The D-ISS demonstrated good internal reliability and test–retest reliability. The D-ISS showed no correlations with divergent scales. For convergent validity, the D-ISS showed moderate correlations with the Dissociative Experiences Scale (DES-II).

The new D-ISS measure of between-mode dissociation is reliable and valid for the population represented by our sample. Further research into its use in clinical populations is required.

Cognitive behavioural therapists and practitioners often feel uncertain about how to treat post-traumatic stress disorder (PTSD) following rape and sexual assault. There are many myths and rumours about what you should and should not do. All too frequently, this uncertainty results in therapists avoiding doing trauma-focused work with these clients. Whilst understandable, this means that the survivor continues to re-experience the rape as flashbacks and/or nightmares. This article outlines an evidence-based cognitive behavioural therapy (CBT) approach to treating PTSD following a rape in adulthood. It aims to be a practical, ‘how to’ guide for therapists, drawing on the authors’ decades of experience in this area. We have included film links to demonstrate how to undertake each step of the treatment pathway. Our aim is for CBT practitioners to feel more confident in delivering effective trauma-focused therapy to this client group. We consider how to assess and formulate PTSD following a rape in adulthood, then how to deliver cognitive therapy for PTSD (CT-PTSD; Ehlers and Clark, 2000). We will cover both client and therapist factors when working with memories of rape, as well as legal, social, cultural and interpersonal considerations.

1. To understand the importance of providing effective, trauma-focused therapy for survivors of rape in adulthood who are experiencing symptoms of PTSD.

2. To be able to assess, formulate and treat PTSD following a rape in adulthood.

3. How to manage the dissociation common in this client group.

4. To be able to select and choose appropriate cognitive, behavioural and imagery techniques to help with feelings of shame, responsibility, anger, disgust, contamination and mistrust.

5. For therapists to learn how best to support their own ability to cope with working in a trauma-focused way with survivors of rape and sexual violence.

Delphi studies allow for the generaztion of a consensus among experts. This has historically been professional experts in their field. This study aimed to obtain a consensus regarding the most important components of cognitive behavioural therapy (CBT) for depression not only for professional experts (therapists) but also for adult experts by experience. Perceptions of importance between therapists and experts by experience differed in multiple areas including content components such as behavioural activation and experiments, psychoeducation, and homework, which the latter did not agree were important. Experts by experience found several components relating to delivery process important which therapists did not, such as delivery method and session length. The strongest agreement from both groups involved the importance of positive therapist factors such as being non-judgemental, knowledgeable, understanding, and trustworthy. Both groups were in agreement on the importance of cognitive restructuring. Neither experts by experience nor therapists met consensus agreement on the inclusion of mindfulness as part of a wider CBT intervention for depression, being rated among the lowest components for both groups. Findings highlight several aspects of CBT content and delivery which may benefit from review in order to increase acceptability for recipients.

1. (1) To identify what recipients and deliverers feel are the most important parts of a CBT intervention for depression.

2. (2) To compare these responses, and consider reasons why these similarities and differences may exist.
