Current psychiatric diagnoses, although heritable, have not been clearly mapped onto distinct underlying pathogenic processes. The same symptoms often occur in multiple disorders, and a substantial proportion of both genetic and environmental risk factors are shared across disorders. However, the relationship between shared symptoms and shared genetic liability is still poorly understood.

Well-characterised, cross-disorder samples are needed to investigate this matter, but few currently exist. Our aim is to develop procedures to purposely curate and aggregate genotypic and phenotypic data in psychiatric research.

As part of the Cardiff MRC Mental Health Data Pathfinder initiative, we have curated and harmonised phenotypic and genetic information from 15 studies to create a new data repository, DRAGON-Data. To date, DRAGON-Data includes over 45 000 individuals: adults and children with neurodevelopmental or psychiatric diagnoses, affected probands within collected families and individuals who carry a known neurodevelopmental risk copy number variant.

We have processed the available phenotype information to derive core variables that can be reliably analysed across groups. In addition, all data-sets with genotype information have undergone rigorous quality control, imputation, copy number variant calling and polygenic score generation.

DRAGON-Data combines genetic and non-genetic information, and is available as a resource for research across traditional psychiatric diagnostic categories. Algorithms and pipelines used for data harmonisation are currently publicly available for the scientific community, and an appropriate data-sharing protocol will be developed as part of ongoing projects (DATAMIND) in partnership with Health Data Research UK.

There is evidence that the COVID-19 pandemic has negatively affected mental health, but most studies have been conducted in the general population.

To identify factors associated with mental health during the COVID-19 pandemic in individuals with pre-existing mental illness.

Participants (N = 2869, 78% women, ages 18–94 years) from a UK cohort (the National Centre for Mental Health) with a history of mental illness completed a cross-sectional online survey in June to August 2020. Mental health assessments were the GAD-7 (anxiety), PHQ-9 (depression) and WHO-5 (well-being) questionnaires, and a self-report question on whether their mental health had changed during the pandemic. Regressions examined associations between mental health outcomes and hypothesised risk factors. Secondary analyses examined associations between specific mental health diagnoses and mental health.

A total of 60% of participants reported that mental health had worsened during the pandemic. Younger age, difficulty accessing mental health services, low income, income affected by COVID-19, worry about COVID-19, reduced sleep and increased alcohol/drug use were associated with increased depression and anxiety symptoms and reduced well-being. Feeling socially supported by friends/family/services was associated with better mental health and well-being. Participants with a history of anxiety, depression, post-traumatic stress disorder or eating disorder were more likely to report that mental health had worsened during the pandemic than individuals without a history of these diagnoses.

We identified factors associated with worse mental health during the COVID-19 pandemic in individuals with pre-existing mental illness, in addition to specific groups potentially at elevated risk of poor mental health during the pandemic.

Pharmacological treatment is widely used for post-traumatic stress disorder (PTSD) despite questions over its efficacy.

To determine the efficacy of all types of pharmacotherapy, as monotherapy, in reducing symptoms of PTSD, and to assess acceptability.

A systematic review and meta-analysis of randomised controlled trials was undertaken; 51 studies were included.

Selective serotonin reuptake inhibitors were found to be statistically superior to placebo in reduction of PTSD symptoms but the effect size was small (standardised mean difference −0.23, 95% CI −0.33 to −0.12). For individual pharmacological agents compared with placebo in two or more trials, we found small statistically significant evidence of efficacy for fluoxetine, paroxetine and venlafaxine.

Some drugs have a small positive impact on PTSD symptoms and are acceptable. Fluoxetine, paroxetine and venlafaxine may be considered as potential treatments for the disorder. For most drugs there is inadequate evidence regarding efficacy for PTSD, pointing to the need for more research in this area.

Self-help interventions for psychiatric disorders represent an increasingly popular alternative to therapist-administered psychological therapies, offering the potential of increased access to cost-effective treatment.

To determine the efficacy, cost-effectiveness and acceptability of self-help interventions for anxiety disorders.

Randomised controlled trials (RCTs) of self-help interventions for anxiety disorders were identified by searching nine online databases. Studies were grouped according to disorder and meta-analyses were conducted where sufficient data were available. Overall meta-analyses of self-help v. waiting list and therapist-administered treatment were also undertaken. Methodological quality was assessed independently by two researchers according to criteria set out by the Cochrane Collaboration.

Thirty-one RCTs met inclusion criteria for the review. Results of the overall meta-analysis comparing self-help with waiting list gave a significant effect size of 0.84 in favour of self-help. Comparison of self-help with therapist-administered treatments revealed a significant difference in favour of the latter with an effect size of 0.34. The addition of guidance and the presentation of multimedia or web-based self-help materials improved treatment outcome.

Self-help interventions appear to be an effective way of treating individuals diagnosed with social phobia and panic disorder. Further research is required to evaluate the cost-effectiveness and acceptability of these interventions.

The effectiveness of official support provided following a disaster has not been fully evaluated. This study aimed to ascertain whether there was an association between perceived support shortly after the 2004 Indian Ocean tsunami and later mental health symptoms in those affected, and to explore the factors associated with this. A survey, semi-structured interviews and focus group were used to explore the experiences and perceptions of 116 individuals severely affected by the tsunami.

Agency or official support was perceived as poor overall. Perceived ineffectiveness of support available within a few days after the tsunami was associated with increased symptoms of post-traumatic stress disorder 15–19 months later. The strongest themes that emerged from our study were that support provided in a humane manner was perceived as effective and that uncoordinated support, poor communication and limited accessibility to support and information were perceived as ineffective.

Improved planning of coordinated, flexible, multi-agency responses to traumatic events before they occur is required.

How best to plan and provide psychosocial care following disasters remains keenly debated.

To develop evidence-informed post-disaster psychosocial management guidelines.

A three-round web-based Delphi process was conducted. One hundred and six experts rated the importance of statements generated from existing evidence using a one to nine scale. Participants reassessed their original scores in the light of others' responses in the subsequent rounds.

A total of 80 (72%) of 111 statements achieved consensus for inclusion. The statement ‘all responses should provide access to pharmacological assessment and management’ did not achieve consensus. The final guidelines recommend that every area has a multi-agency psychosocial care planning group, that responses provide general support, access to social, physical and psychological support and that specific mental health interventions are only provided if indicated by a comprehensive assessment. Trauma-focused cognitive–behavioural therapy (CBT) is recommended for acute stress disorder or acute post-traumatic stress disorder, with other treatments with an evidence base for chronic post-traumatic stress disorder being made available if trauma-focused CBT is not tolerated.

The Delphi process allowed a consensus to be achieved in an area where there are limitations to the current evidence.

The Mental Capacity Act for England and Wales empowers individuals to plan ahead for when they may lack capacity.

To develop a care pathway for advance decisions and powers of attorney using Huntington's disease as an exemplar.

Qualitative study using in-depth individual interviews with service users and carers, and focus groups with professionals. Inductive qualitative analysis was used to develop themes to construct a care pathway that was then piloted and further evaluated to achieve a final pathway.

A care pathway was developed that incorporated an early introduction through a formal education session and a minimum of two sessions separated by at least 2 weeks before advance decision completion. Optimal delivery of this intervention requires significant clinical and administrative commitment.

We have developed a simple, easy-to-follow care pathway that was acceptable to users and providers.

To determine the nature of current liaison psychiatry services in Wales, a structured telephone interview was conducted with representatives of all 11 National Health Service trusts.

Three trusts (27%) had no dedicated liaison psychiatry service and only one of the eight (13%) with a service had a full-time consultant liaison psychiatrist. Only two services (25%) had a full-time junior doctor and three (37%) were not multidisciplinary, comprising nursing staff alone. No team had a clinical psychologist and only two (25%) provided a psychological treatment service.

Liaison psychiatry services across Wales are fragmented, under-resourced and unlikely to meet patients' needs. They fall well short of the recommendations of the Royal Colleges of Physicians and Psychiatrists.
