ABSTRACT
We argue that editorial independence, through robust practice of publication ethics and research integrity, promotes good science and prevents bad science. We elucidate the concept of research integrity, and then discuss the dimensions of editorial independence. Best practice guidelines exist, but compliance with these guidelines varies. Therefore, we make recommendations for protecting and strengthening editorial independence.
ABSTRACT
BACKGROUND: Here, we (a) examined the trajectories of night-time sleep duration, bedtime and midpoint of night-time sleep (MPS) from infancy to adolescence, and (b) explored perinatal risk factors for persistent poor sleep health. METHODS: This study used data from 12,962 participants in the Avon Longitudinal Study of Parents and Children (ALSPAC). Parent or self-reported night-time sleep duration, bedtime and wake-up time were collected from questionnaires at 6, 18 and 30 months, and at 3.5, 4-5, 5-6, 6-7, 9, 11 and 15-16 years. Child's sex, birth weight, gestational age, health and temperament, together with mother's family adversity index (FAI), age at birth, prenatal socioeconomic status and postnatal anxiety and depression, were included as risk factors for persistent poor sleep health. Latent class growth analyses were applied first to detect trajectories of night-time sleep duration, bedtime and MPS, and we then applied logistic regressions for the longitudinal associations between risk factors and persistent poor sleep health domains. RESULTS: We obtained four trajectories for each of the three sleep domains. In particular, we identified a trajectory characterized by persistent shorter sleep, a trajectory of persistent later bedtime and a trajectory of persistent later MPS. Two risk factors were associated with the three poor sleep health domains: higher FAI with increased risk of persistent shorter sleep (OR = 1.20, 95% CI = 1.11-1.30, p < .001), persistent later bedtime (OR = 1.28, 95% CI = 1.19-1.39, p < .001) and persistent later MPS (OR = 1.30, 95% CI = 1.22-1.38, p < .001); and higher maternal socioeconomic status with reduced risk of persistent shorter sleep (OR = 0.99, 95% CI = 0.98-1.00, p = .048), persistent later bedtime (OR = 0.98, 95% CI = 0.97-0.99, p < .001) and persistent later MPS (OR = 0.99, 95% CI = 0.98-0.99, p < .001). CONCLUSIONS: We detected trajectories of persistent poor sleep health (i.e. shorter sleep duration, later bedtime and later MPS) from infancy to adolescence, and specific perinatal risk factors linked to persistent poor sleep health domains.
ABSTRACT
BACKGROUND: Cannabis use is a global public health issue associated with increased risks of developing mental health disorders, especially in young people. We aimed to investigate the relationships between cannabis exposure and risks of receiving mental illness diagnoses or treatment as outcomes. METHODS: A population based, retrospective, open cohort study using patients recorded in 'IQVIA medical research data', a UK primary care database. Read codes were used to confirm patients with recorded exposure to cannabis use who were matched up to two unexposed patients. We examined the risk of developing three categories of mental ill health: depression, anxiety or serious mental illness (SMI). RESULTS: At study entry, the exposed cohort had an increased likelihood of having experienced mental ill health [odds ratio (OR) 4.13; 95% confidence interval (CI) 3.99-4.27] and mental ill health-related prescription (OR 2.95; 95% CI 2.86-3.05) compared to the unexposed group. During the study period we found that exposure to cannabis was associated with an increased risk of developing any mental disorder [adjusted hazard ratio (aHR) 2.73; 95% CI 2.59-2.88], also noted when examining by subtype of disorder: anxiety (aHR 2.46; 95% CI 2.29-2.64), depression (aHR 2.34; 95% CI 2.20-2.49) and SMI (aHR 6.41; 95% CI 5.42-7.57). These results remained robust in sensitivity analyses. CONCLUSION: These findings point to the potential need for a public health approach to the management of people misusing cannabis. However, there is a gross under-recording of cannabis use in GP records, as seen by the prevalence of recorded cannabis exposure substantially lower than self-reported survey records.

Borderline personality disorder (BPD) is a complex mental health condition often associated with previous childhood adversity including maladaptive parenting. When becoming a parent themselves, mothers with BPD have difficulties with various parenting cognitions and practices, but unknown is whether they have appropriate knowledge of sensitive parenting. This study explored whether differences in parenting knowledge or self-efficacy are specific to BPD or also found in mothers with depression, and whether symptom severity or specific diagnosis better explain parenting perceptions. Mothers with BPD (n = 26), depression (n = 25) or HCs (n = 25) completed a Q-sort parenting knowledge task and a parenting self-efficacy questionnaire. Results showed mothers with BPD had the same knowledge of sensitive parenting behaviors as mothers with depression and healthy mothers. Self-reported parenting self-efficacy was lower in mothers with BPD and depression compared with healthy mothers, with symptom severity most strongly associated. A significant but low correlation was found between parenting self-efficacy and knowledge. Findings suggest that mothers with BPD and depression know what good parenting is but think they are not parenting well. Mental health difficulties are not associated with parenting knowledge, but symptom severity appears to be a common pathway to lower parenting self-efficacy. Future interventions should test whether reduction of symptom severity or positive parenting feedback could improve parenting self-efficacy.
ABSTRACT
Psychiatric involvement in patient morality is controversial. If psychiatrists are tasked with shaping patient morality, the coercive potential of psychiatry is increased, treatment may be unfairly administered on the basis of patients' moral beliefs rather than medical need, moral disputes could damage the therapeutic relationship and, in any case, we are often uncertain or conflicted about what is morally right. Yet, there is also a strong case for the view that psychiatry often works through improving patient morality and, therefore, should aim to do so. Our goal is to offer a practical and ethical path through this conflict. We argue that the default psychiatric approach to patient morality should be procedural, whereby patients are helped to express their own moral beliefs. Such a procedural approach avoids the brunt of objections to psychiatric involvement in patient morality. However, in a small subset of cases where patients' moral beliefs are sufficiently distorted or underdeveloped, we claim that psychiatrists should move to a substantive approach and shape the content of those beliefs when they are relevant to psychiatric outcomes. The substantive approach is prone to the above objections but we argue it is nevertheless justified in this subset of cases.

Most mental health research largely ignores or minimises gender and age differences in depression. In 'Don't mind the gap: Why do we not care about the gender gap in mental health?', Patalay and Demkowicz identify a dearth of research on the causal factors of depression in young women. They attribute this to an over-reliance on biological accounts of gender differences in depression. Patalay and Demkowicz conclude that a person-centred approach that meaningfully engages with the reports of young women with depression is more likely to expose the social drivers of depression that impact this group. This commentary focuses on Patalay and Demkowicz's call to examine the patient's lived experience. We argue that there is an urgent need to reflect upon the methodologies involved in examining lived experience and how they can be best utilised. Ultimately, we advocate for an approach known as 'phenomenological psychopathology', through a phenomenological investigation of depression in young women, we can go some way towards closing the gender gap.

ABSTRACT
BACKGROUND: Preventing psychotic disorders and effective treatment in first-episode psychosis are key priorities for the National Institute for Health and Care Excellence. This review assessed the evidence base for the cost-effectiveness of health and social care interventions for people at risk of psychosis and for first-episode psychosis. METHODS: Electronic searches were conducted using the PsycINFO, MEDLINE and Embase databases to identify relevant published full economic evaluations published before August 2020. Full-text English-language studies reporting a full economic evaluation of a health or social care intervention aiming to reduce or prevent symptoms in people at risk of psychosis or experiencing first-episode psychosis were included. Screening, data extraction, and critical appraisal were performed using pre-specified criteria and forms based on the NHS Economic Evaluation Database (EED) handbook and Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist for economic evaluations. The protocol was registered on the PROSPERO database (CRD42018108226). Results were summarised qualitatively. RESULTS: Searching identified 1,628 citations (1,326 following the removal of duplications). After two stages of screening 14 studies met the inclusion criteria and were included in the review. Interventions were varied and included multidisciplinary care, antipsychotic medication, psychological therapy, and assertive outreach. Evidence was limited in the at-risk group with only four identified studies, though all interventions were found to be cost-effective with a high probability (> 80%). A more substantial evidence base was identified for first-episode psychosis (11 studies), with a focus on early intervention (7/11 studies) which again had positive conclusions though with greater uncertainty. CONCLUSIONS: Study findings generally concluded interventions were cost-effective. The evidence for the population who are at-risk of psychosis was limited, and though there were more studies for the population with first-episode psychosis, limitations of the evidence base (including generalisability and heterogeneity across the methods used) affect the certainty of conclusions.

BACKGROUND: Reducing bullying is a public health priority. KiVa, a school-based anti-bullying programme, is effective in reducing bullying in Finland and requires rigorous testing in other countries, including the UK. This trial aims to test the effectiveness and cost-effectiveness of KiVa in reducing child reported bullying in UK schools compared to usual practice. The trial is currently on-going. Recruitment commenced in October 2019, however due to COVID-19 pandemic and resulting school closures was re-started in October 2020. METHODS: Design: Two-arm pragmatic multicentre cluster randomised controlled trial with an embedded process and cost-effectiveness evaluation. PARTICIPANTS: 116 primary schools from four areas; North Wales, West Midlands, South East and South West England. Outcomes will be assessed at student level (ages 7-11 years; n = approximately 13,000 students). INTERVENTION: KiVa is a whole school programme with universal actions that places a strong emphasis on changing bystander behaviour alongside indicated actions that provide consistent strategies for dealing with incidents of bullying. KiVa will be implemented over one academic year. COMPARATOR: Usual practice. PRIMARY OUTCOME: Student-level bullying-victimisation assessed through self-report using the extensively used and validated Olweus Bully/Victim questionnaire at baseline and 12-month follow-up. SECONDARY OUTCOMES: student-level bullying-perpetration; student mental health and emotional well-being; student level of, and roles in, bullying; school related well-being; school attendance and academic attainment; and teachers' self-efficacy in dealing with bullying, mental well-being, and burnout. SAMPLE SIZE: 116 schools (58 per arm) with an assumed ICC of 0.02 will provide 90% power to identify a relative reduction of 22% with a 5% significance level. RANDOMISATION: recruited schools will be randomised on 1:1 basis stratified by Key-Stage 2 size and free school meal status. Process evaluation: assess implementation fidelity, identify influences on KiVa implementation, and examine intervention mechanisms. Economic evaluation: Self-reported victimisation, Child Health Utility 9D, Client Service Receipt Inventory, frequency of services used, and intervention costs. The health economic analysis will be conducted from a schools and societal perspective. DISCUSSION: This two-arm pragmatic multicentre cluster randomised controlled trial will evaluate the KiVa anti-bullying intervention to generate evidence of the effectiveness, cost-effectiveness and scalability of the programme in the UK. Our integrated process evaluation will assess implementation fidelity, identify influences on KiVa implementation across England and Wales and examine intervention mechanisms. The integrated health economic analysis will be conducted from a schools and societal perspective. Our trial will also provide evidence regarding the programme impact on inequalities by testing whether KiVa is effective across the socio-economic gradient. TRIAL REGISTRATION: Trials ISRCTN 12300853 Date assigned 11/02/2020.

OBJECTIVES: Research has suggested people who hear voices may be at risk of epistemic injustice. This is a form of discrimination whereby someone is unfairly judged to be an unreliable knower (testimonial injustice) or is unable to contribute to, and therefore access, concepts that make sense of their experience within mainstream society (hermeneutical injustice). Voice-hearing occurs both in people who are mental health service users and in the general population (clinical and non-clinical voice-hearers, respectively). The degree of distress and impairment associated with voices has been shown to relate to how individuals make sense of their experiences and how others respond to their identity as a voice-hearer. The aim of this study was to explore people's experiences of epistemic injustice in relation to voice-hearing and to understand how these may differ between clinical and non-clinical voice-hearers. DESIGN: A qualitative design was used. METHOD: Eight clinical and nine non-clinical voice-hearers partook in semi-structured interviews, which were analysed using thematic analysis. RESULTS: Three pairs of themes related to (i) identity, (ii) relationships and (iii) power and position were constructed across the clinical and non-clinical groups, and two shared themes within both groups were created relating to testimonial and hermeneutical injustice. CONCLUSION: Both clinical and non-clinical voice-hearers described experiencing epistemic injustice in wider society. The presence of a 'safe haven' (e.g. spiritualist churches) for non-clinical voice-hearers ameliorated the impact of this to some degree, by allowing people to make connections with others with similar experiences within a non-judgemental and accepting community.

When young people seek support from mental health care practitioners, the encounters may affect the young people's sense of self, and in particular undermine their sense of agency. For this study, an interdisciplinary team of academics and young people collaboratively analysed video-recorded encounters between young people and mental healthcare practitioners in emergency services. They identified five communication techniques that practitioners can use to avoid undermining the young person's sense of agency in the clinical encounter. They conceptualise the use of those techniques as the adoption of an agential stance towards the young person. The agential stance consists of: (a) validating the young person's experiences, (b) legitimising the young person's choice to seek help, (c) refraining from objectifying the young person, (d) affirming the young person's capacity to contribute to positive change, and (e) involving the young person in the decision-making process.
ABSTRACT
The ability to identify biomarkers of psychosis risk is essential in defining effective preventive measures to potentially circumvent the transition to psychosis. Using samples of people at clinical high risk for psychosis (CHR) and Healthy controls (HC) who were administered a task fMRI paradigm, we used a framework for labelling time windows of fMRI scans as 'integrated' FC networks to provide a granular representation of functional connectivity (FC). Periods of integration were defined using the 'cartographic profile' of time windows and k-means clustering, and sub-network discovery was carried out using Network Based Statistics (NBS). There were no network differences between CHR and HC groups. Within the CHR group, using integrated FC networks, we identified a sub-network negatively associated with longitudinal changes in the severity of psychotic symptoms. This sub-network comprised brain areas implicated in bottom-up sensory processing and in integration with motor control, suggesting it may be related to the demands of the fMRI task. These data suggest that extracting integrated FC networks may be useful in the investigation of biomarkers of psychosis risk.

In the healthy brain, homeostatic balance between excitation and inhibition maintains neural stability. Reduced inhibition may explain shared symptoms observed in autism and psychosis. Here we review evidence suggesting that altered levels of gamma-aminobutyric acid (GABA) may underlie both disorders, providing a potential cross-diagnostic therapeutic target.

Heterostructures built from 2D, atomically thin crystals are bound by the van der Waals force and exhibit unique optoelectronic properties. Here, we report the structure, composition and optoelectronic properties of 1D van der Waals heterostructures comprising carbon nanotubes wrapped by atomically thin nanotubes of boron nitride and molybdenum disulfide (MoS2). The high quality of the composite was directly made evident on the atomic scale by transmission electron microscopy, and on the macroscopic scale by a study of the heterostructure's equilibrium and ultrafast optoelectronics. Ultrafast pump-probe spectroscopy across the visible and terahertz frequency ranges identified that, in the MoS2 nanotubes, excitons coexisted with a prominent population of free charges. The electron mobility was comparable to that found in high-quality atomically thin crystals. The high mobility of the MoS2 nanotubes highlights the potential of 1D van der Waals heterostructures for nanoscale optoelectronic devices.
ABSTRACT
A good therapeutic relationship in mental health services is a predictor of positive clinical outcomes for people who seek help for distressing experiences, such as voice hearing and paranoia. One factor that may affect the quality of the therapeutic relationship and raises further ethical issues is the impact of the clinical encounter on users' sense of self, and in particular on their sense of agency. In the paper, we discuss some of the reasons why the sense of epistemic agency may be especially fragile in young people with unusual experiences and beliefs. We argue that it is important to identify and avoid behaviours that can undermine young people's contributions as epistemic agents in the clinical encounter.
ABSTRACT
BACKGROUND: Childhood abuse is a risk factor for poorer illness course in bipolar disorder, but the reasons why are unclear. Trait-like features such as affective instability and impulsivity could be part of the explanation. We aimed to examine whether childhood abuse was associated with clinical features of bipolar disorder, and whether associations were mediated by affective instability or impulsivity. METHODS: We analysed data from 923 people with bipolar I disorder recruited by the Bipolar Disorder Research Network. Adjusted associations between childhood abuse, affective instability and impulsivity and eight clinical variables were analysed. A path analysis examined the direct and indirect links between childhood abuse and clinical features with affective instability and impulsivity as mediators. RESULTS: Affective instability significantly mediated the association between childhood abuse and earlier age of onset [effect estimate (θ)/standard error (SE): 2.49], number of depressive (θ/SE: 2.08) and manic episodes/illness year (θ/SE: 1.32), anxiety disorders (θ/SE: 1.98) and rapid cycling (θ/SE: 2.25). Impulsivity significantly mediated the association between childhood abuse and manic episodes/illness year (θ/SE: 1.79), anxiety disorders (θ/SE: 1.59), rapid cycling (θ/SE: 1.809), suicidal behaviour (θ/SE: 2.12) and substance misuse (θ/SE: 3.09). Measures of path analysis fit indicated an excellent fit to the data. CONCLUSIONS: Affective instability and impulsivity are likely part of the mechanism of why childhood abuse increases risk of poorer clinical course in bipolar disorder, with each showing some selectivity in pathways. They are potential novel targets for intervention to improve outcome in bipolar disorder.

Background: Whilst robust preclinical and postmortem evidence suggests that altered GABAergic function is central to the development of psychosis, little is known about whether it is altered in subjects at ultra-high risk of psychosis, or its relationship to prodromal symptoms. Methods: Twenty-one antipsychotic naïve ultra-high risk individuals and 20 healthy volunteers underwent proton magnetic resonance imaging at 3T. Gamma-aminobutyric acid levels were obtained from the medial prefrontal cortex using MEGA-PRESS and expressed as peak-area ratios relative to the synchronously acquired creatine signal. Gamma-aminobutyric acid levels were then related to severity of positive and negative symptoms as measured with the Community Assessment of At-Risk Mental States. Results: Whilst we found no significant difference in gamma-aminobutyric acid levels between ultra-high risk subjects and healthy controls (P=.130), in ultra-high risk individuals, medial prefrontal cortex GABA levels were negatively correlated with the severity of negative symptoms (P=.013). Conclusion: These findings suggest that gamma-aminobutyric acidergic neurotransmission may be involved in the neurobiology of negative symptoms in the ultra-high risk state.

BACKGROUND: Our view is that sleep disturbance may be a contributory causal factor in the development and maintenance of psychotic experiences. A recent series of randomized controlled intervention studies has shown that cognitive-behavioural approaches can improve sleep in people with psychotic experiences. However, the effects of psychological intervention for improving sleep have not been evaluated in young people at ultra-high risk of psychosis. Improving sleep might prevent later transition to a mental health disorder. AIMS: To assess the feasibility and acceptability of an intervention targeting sleep disturbance in young people at ultra-high risk of psychosis. METHOD: Patients were sought from NHS mental health services. Twelve young people at ultra-high risk of psychosis with sleep problems were offered an eight-session adapted CBT intervention for sleep problems. The core treatment techniques were stimulus control, circadian realignment, and regulating day-time activity. Participants were assessed before and after treatment and at a one month follow-up. RESULTS: All eligible patients referred to the study agreed to take part. Eleven patients completed the intervention, and one patient withdrew after two sessions. Of those who completed treatment, the attendance rate was 89% and an average of 7.6 sessions (SD = 0.5) were attended. There were large effect size improvements in sleep. Post-treatment, six patients fell below the recommended cut-off for clinical insomnia. There were also improvements in negative affect and psychotic experiences. CONCLUSION: This uncontrolled feasibility study indicates that treating sleep problems in young people at ultra-high of psychosis is feasible, acceptable, and may be associated with clinical benefits.

OBJECTIVE: Little is known about how first episode bipolar disorder (BD) is managed in early intervention for psychosis services (EIS). We aimed to investigate the knowledge and views of EIS staff on the assessment and treatment of BD. METHODS: A 27-item anonymised online questionnaire was distributed to EIS mental health professionals in England. Descriptive data analysis was undertaken. RESULTS: Responses were received from 117 EIS staff. Most were 'fairly confident' in their knowledge about causes, presentations and relapse indicators of BD, but less confident on pharmacological and psychological treatments. Eighty five percent expressed the view that more BD training was necessary in this area with 78% reporting no clear care packages within the service. Seventy two percent believe early BD should be treated within EIS only if patients have psychosis. CONCLUSIONS: Clearer care packages and staff training are needed for EIS staff to optimise care for BD.
