RESUMEN

BACKGROUND: School-based early intervention may alleviate current emotional and behavioural problems, and, by targeting underlying vulnerability, safeguard children's future mental health. Improving on mixed outcomes to date is an international public health priority. CUES-Ed is a classroom-based, clinician-led, universal cognitive behavioural programme for primary school children, designed to promote emotional literacy and regulation. Additionally, CUES-Ed targets cognitive mechanisms implicated in the future development of mental disorder: stigmatising appraisals of emotional expression and of unusual perceptual experiences, and the tendency to jump-to-conclusions (JTC). We report here on fitness for purpose of our in-service assessment of cognitive vulnerability, and change in cognitive vulnerability following CUES-Ed and compared with a naturalistic waitlist. METHODS: From 05/2017-11/2017, 960 children participated (900 CUES-Ed; 60 naturalistic waitlist). Assessments were completed in whole classes; 732 children provided pre-post data on all measures; 227 were missing data through absence or poor completion (n = 1 declined assessment). RESULTS: Relationships between baseline cognitive vulnerability measures and their components were consistent with reliable and valid assessment. Cognitive vulnerability reduced from before to after CUES-Ed and compared with the naturalistic waitlist, for JTC (large effects) and stigmatising appraisals (small-medium effects), for all children (ESs pre-post: 0.2-1.0; between-group: 0.1-1.0) and vulnerable subgroups (ESs pre-post: 0.5-1.7; between-group: 0.2-2.0). CONCLUSIONS: Targeted cognitive vulnerability mechanisms change following CUES-Ed. As stigmatising appraisals and JTC may increase vulnerability to future mental illness, findings suggest a promise in reducing future risk. A formally controlled research study, with longer-term follow-up, is required to test this. Limitations and implications for future evaluation are discussed.

RESUMEN

BACKGROUND: People with psychosis have high rates of trauma, with a post-traumatic stress disorder (PTSD) prevalence rate of approximately 15%, which exacerbates psychotic symptoms such as delusions and hallucinations. Pilot studies have shown that trauma-focused (TF) psychological therapies can be safe and effective in such individuals. This trial, the largest to date, will evaluate the clinical effectiveness of a TF therapy integrated with cognitive behaviour therapy for psychosis (TF-CBTp) on post-traumatic stress symptoms in people with psychosis. The secondary aims are to compare groups on cost-effectiveness; ascertain whether TF-CBTp impacts on a range of other meaningful outcomes; determine whether therapy effects endure; and determine acceptability of the therapy in participants and therapists. METHODS: Rater-blind, parallel arm, pragmatic randomised controlled trial comparing TF-CBTp + treatment as usual (TAU) to TAU only. Adults (N = 300) with distressing post-traumatic stress and psychosis symptoms from five mental health Trusts (60 per site) will be randomised to the two groups. Therapy will be manualised, lasting 9 months (m) with trained therapists. We will assess PTSD symptom severity (primary outcome); percentage who show loss of PTSD diagnosis and clinically significant change; psychosis symptoms; emotional well-being; substance use; suicidal ideation; psychological recovery; social functioning; health-related quality of life; service use, a total of four times: before randomisation; 4 m (mid-therapy); 9 m (end of therapy; primary end point); 24 m (15 m after end of therapy) post-randomisation. Four 3-monthly phone calls will be made between 9 m and 24 m assessment points, to collect service use over the previous 3 months. Therapy acceptability will be assessed through qualitative interviews with participants (N = 35) and therapists (N = 5-10). An internal pilot will ensure integrity of trial recruitment and outcome data, as well as therapy protocol safety and adherence. Data will be analysed following intention-to-treat principles using generalised linear mixed models and reported according to Consolidated Standards of Reporting Trials-Social and Psychological Interventions Statement. DISCUSSION: The proposed intervention has the potential to provide significant patient benefit in terms of reductions in distressing symptoms of post-traumatic stress, psychosis, and emotional problems; enable clinicians to implement trauma-focused therapy confidently in this population; and be cost-effective compared to TAU through reduced service use. TRIAL REGISTRATION: ISRCTN93382525 (03/08/20).

RESUMEN

Anomalous perceptual experiences are relatively common in the general population. Evidence indicates that the key to distinguishing individuals with persistent psychotic experiences (PEs) with a need for care from those without is how they appraise their anomalous experiences. Here, we aimed to characterise the neural circuits underlying threatening and non-threatening appraisals in people with and without a need for care for PEs, respectively. A total of 48 participants, consisting of patients with psychosis spectrum disorder (clinical group, n = 16), non-need-for-care participants with PEs (non-clinical group, n = 16), and no-PE healthy control participants (n = 16), underwent functional magnetic resonance imaging while completing the Telepath task, designed to induce an anomalous perceptual experience. Appraisals of the anomalous perceptual experiences were examined, as well as functional brain responses during this window, for significant group differences. We also examined whether activation co-varied with the subjective threat appraisals reported in-task by participants. The clinical group reported elevated subjective threat appraisals compared to both the non-clinical and no-PE control groups, with no differences between the two non-clinical groups. This pattern of results was accompanied by reduced activation in the superior and inferior frontal gyri in the clinical group as compared to the non-clinical and control groups. Precuneus activation scaled with threat appraisals reported in-task. Resilience in the context of persistent anomalous experiences may be explained by intact functioning of fronto-parietal regions, and may correspond to the ability to contextualise and flexibly evaluate psychotic experiences.

RESUMEN

Existing models of emotion processing are based almost exclusively on brain activation data, yet make assumptions about network connectivity. There is a need to integrate connectivity findings into these models. We systematically reviewed all studies of functional and effective connectivity employing tasks to investigate negative emotion processing and regulation in healthy participants. Thirty-three studies met inclusion criteria. A quality assessment tool was derived from prominent neuroimaging papers. The evidence supports existing models, with primarily limbic regions for salience and identification, and frontal areas important for emotion regulation. There was mixed support for the assumption that regulatory influences on limbic and sensory areas come predominantly from prefrontal areas. Rather, studies quantifying effective connectivity reveal context-dependent dynamic modulatory relationships between occipital, subcortical, and frontal regions, arguing against purely top-down regulatory theoretical models. Our quality assessment tool found considerable variability in study design and tasks employed. The findings support and extend those of previous syntheses focused on activation studies, and provide evidence for a more nuanced view of connectivity in networks of human emotion processing and regulation.

RESUMEN

OBJECTIVE: We aimed to describe patients' views of a new referral pathway of general practitioner (GP) direct access to MRI, versus imaging after referral to a specialist. DESIGN: This qualitative study involved 20 semistructured interviews. Twenty patients (10 from each pathway) were purposively recruited and interviewed to describe their attitudes. SETTING: A neurology headache clinic and neuroradiology services from the boroughs of Southwark and Lambeth in South London, UK. PARTICIPANTS: Twenty patients were involved in this study. RESULTS: Over half of the participants felt relieved once they received their scan results, while some remained uncertain about the underlying cause of their symptoms. Some participants described a long wait to see a specialist. Others described a long wait time to receive scan results, especially from their GP. Spontaneous reduction in headache symptoms occurred for some participants and for others, normal imaging results allowed them to focus more on symptom management. CONCLUSION: Relief was reported especially when scan results had been explained clearly and without too much delay. Those with continuing pain focused on how to get relief from symptoms. Patient experience might be improved with clearer information from GPs about how patients can access results, standard reporting procedures and closer liaison between neuroradiology and GPs.

RESUMEN

BACKGROUND: Biomedical research from low- and middle-income countries (LMICs) is poorly represented in Western European and North American psychiatric journals.AimsTo test the feasibility of trialling a capacity-building intervention to improve LMIC papers' representation in biomedical journals. METHOD: We designed an enhanced peer-review intervention delivered to LMIC corresponding/first authors of papers rejected by the British Journal of Psychiatry. We conducted a feasibility study, inviting consenting authors to be randomised to intervention versus none, measuring recruitment and retention rates, outcome completion and author/reviewer-rated acceptability. RESULTS: Of the 26/121 consenting to participate, 12 were randomised to the intervention and 14 to the control arms. Outcome completion was 100% but qualitative feedback from authors/reviewers was mixed, with attrition from 5/12 (42%) of intervention reviewers. CONCLUSIONS: Low interest among eligible authors and variable participation of expert reviewers suggested low feasibility of a full trial and a need for intervention redesign.Declaration of interestA.P., P.T. and M.Y. are British Journal of Psychiatry editorial board members. During this study P.T. was British Journal of Psychiatry Editor, A.P. was a trainee editor and A.H. was an editorial assistant.

RESUMEN

OBJECTIVES: To develop a better understanding of general practitioners' (GPs) views and experiences of the management of patients with headaches and use of direct-access MRI scans, and observe outcomes of an educational session offered by a GP with a special interest (GPwSI) to GPs. DESIGN: A qualitative study using semistructured interviews, analysed using thematic analysis. A GPwSI in headaches visited practices delivering a talk on headache medication, diagnosis and management. SETTING: Sixteen (16) primary care family practices in South London, UK. PARTICIPANTS: Twenty (20) GPs. RESULTS: Not all GPs were aware of the availability of direct-access MRI, but all acknowledged having used referral or direct scans to manage patients' concern about their headaches. A normal scan result helped resolve uncertainty for patient and GP and helped management towards discussion of preventative treatment. However, patients with psychological and/or severe headache symptoms could not necessarily be reassured. GPs reported difficulty interpreting radiology reports, particularly incidental abnormalities. Those who received the educational talk gained knowledge in diagnosis and medication, improving their confidence in management. CONCLUSIONS: Increased access to imaging, training in headache management, addressing physical and psychological symptoms and standardised reporting of scans may improve GPs' use of direct-access MRI in the future.

RESUMEN

Cognitive models of psychosis propose that maladaptive appraisals of anomalous experiences contribute to distress and disability in psychosis. Attentional, attributional and reasoning biases are hypothesised to drive these threat-based appraisals. Experimental and self-report data have provided support for the presence of these biases in psychosis populations, but recently there have been calls for neurobiological data to be integrated into these findings. Currently, little investigation has been conducted into the neural correlates of maladaptive appraisals. Experimental and neuroimaging research in social cognition employing threatening stimuli provide the closest equivalent of maladaptive appraisal in psychosis. Consequently, a rapprochement of these two literatures was attempted in order to identify neural networks relevant to threat appraisal in psychosis. This revealed overlapping models of aberrant emotion processing in anxiety and schizophrenia, encompassing the amygdala, insula, hippocampus, anterior cingulate cortex, and prefrontal cortex. These models posit that aberrant activity in these systems relates to altered emotional significance detection and affect regulation, providing a conceptual overlap with threat appraisal in psychosis, specifically attentional and attributional biases towards threat. It remains to be seen if direct examination of these biases using neuroimaging paradigms supports the theoretical integration of extant models of emotion processing and maladaptive appraisals in psychosis.

RESUMEN

Previous research has linked certain types of modern spirituality, including New Age and Pagan, with either benign schizotypy or insecure attachment. While the first view emphasizes a positive aspect of spiritual believers' mental health (benign schizotypy), the second view emphasizes a negative aspect, namely the unhealthy emotional compensation associated with an insecure attachment style. This study addresses these two conflicting views by comparing a sample of modern spiritual individuals (N = 114) with a contrast group of traditional religious believers (N = 86). Measures of schizotypy and attachment style were combined with mental health scales of anxiety and depression. We further assessed death anxiety to determine whether modern spiritual beliefs fulfilled a similar function as traditional religious beliefs in the reduction of existential threat. Our results support a psychological contiguity between traditional and modern spiritual believers and reinforce the need to de-stigmatize spiritual ideas and experiences. Using hierarchical regression, we showed that unusual experiences and ideas are the major predictor of engagement in modern spiritual practices. Anxiety, depression variables, and insecure attachment were not significant predictors of spirituality or correlated with them; on the other hand, the results show that spiritual believers report high social support satisfaction and this variable predicts involvement in modern spirituality. Further, spiritual practices were negatively correlated with and negatively predicted by death anxiety scores. Overall, the results strengthen the association between modern spirituality, good mental health, and general well-being.
