Children of parents with mental disorder face multiple challenges. To summarise evidence about parental mental disorder and child physical health. We searched seven databases for cohort or case-control studies quantifying associations between parental mental disorders (substance use, psychotic, mood, anxiety, obsessive-compulsive, post-traumatic stress and eating) and offspring physical health. Studies were excluded if: they reported perinatal outcomes only (<28 days) or outcomes after age 18; they measured outcome prior to exposure; or the sample was drawn from diseased children. A meta-analysis was conducted. The protocol was registered on the PROSPERO database (CRD42017072620). Searches revealed 15 945 non-duplicated studies. Forty-one studies met our inclusion criteria: ten investigated accidents/injuries; eight asthma; three other atopic diseases; ten overweight/obesity; ten studied other illnesses (eight from low-and middle-income countries (LMICs)). Half of the studies investigated maternal perinatal mental health, 17% investigated paternal mental disorder and 87% examined maternal depression. Meta-analysis revealed significantly higher rates of injuries (OR = 1.15, 95% CI 1.04-1.26), asthma (OR = 1.26, 95% CI 1.12-1.41) and outcomes recorded in LMICs (malnutrition: OR = 2.55, 95% CI 1.74-3.73; diarrhoea: OR = 2.16, 95% CI 1.65-2.84). Evidence was inconclusive for obesity and other atopic disorders. Children of parents with mental disorder have health disadvantages; however, the evidence base is limited to risks for offspring following postnatal depression in mothers and there is little focus on fathers in the literature. Understanding the physical health risks of these vulnerable children is vital to improving lives. Future work should focus on discovering mechanisms linking physical and mental health across generations. None.

Although self-help interventions are effective in treating depression, less is known about the factors that determine effectiveness (i.e. moderators of effect). This study sought to determine whether the content of self-help interventions, the study populations or aspects of study design were the most important moderators. Randomized trials of the effectiveness of self-help interventions versus controls in the treatment of depressive symptoms were identified using previous reviews and electronic database searches. Data on moderators (i.e. patient populations, study design, intervention content) and outcomes were extracted and analysed using meta-regression. Thirty-four studies were identified with 39 comparisons. Study design factors associated with greater effectiveness were unclear allocation concealment, observer-rated outcome measures and waiting-list control groups. Greater effectiveness was also associated with recruitment in non-clinical settings, patients with existing depression (rather than those 'at risk'), contact with a therapist (i.e. guided self-help) and the use of cognitive behavioural therapy (CBT) techniques. However, only guided self-help remained significant in the multivariate analysis [regression coefficient 0.36, 95% confidence interval (CI) 0.05-0.68, p=0.03]. In the subset of guided studies, there were no significant associations between outcomes and the session length, content, delivery mode or therapist background. The results provide some insights into moderators of self-help interventions, which might assist in the design of future interventions. However, the present study did not provide a comprehensive description, and other research methods might be required to identify factors associated with the effectiveness of self-help.

Background Type 2 diabetes mellitus is preventable through lifestyle intervention. Diabetes prevention programmes (DPPs) aim to deliver prevention-based behaviour change interventions to reduce incidence. Such programmes vary from usual primary care in terms of where, how, and by whom they are delivered. Implementation is therefore likely to face new commissioning, incentive and delivery challenges. We report on the implementation of a national DPP in NHS England, and identify lessons learned in addressing the implementation challenges. Methods In 2017/18, we conducted 20 semi-structured telephone interviews covering 16 sampled case sites with the designated lead(s) responsible for local implementation of the programme. Interviews explored the process of implementation, including organisation of the programme, expectations and attitudes to the programme, funding, target populations and referral and clinical pathways. We drew on constant comparative methods to analyse the data and generate over-arching themes. We complemented our qualitative data with a survey focused on variation in the financial incentives used across sites to ensure usual primary care services recruited patients to new providers. Results We identified five over-arching areas of learning for implementing this large-scale programme: 1) managing new providers; 2) promoting awareness of services; 3) recruiting patients; 4) incentive payments; and 5) mechanisms for sharing learning. In general, tensions appeared to be caused by a lack of clear roles/responsibilities between hierarchical actors, and lack of communication. Both local sites and the national NHS coordination team gained experience through learning by doing. Initial tensions with roles and expectations have been worked out during implementation. Conclusions Implementing a national disease prevention programme is a major task, and one that will be increasingly faced by health systems globally as they aim to adjust to demand pressures. We provide practical learning opportunities for the wider uptake and sustainability of prevention programmes. Future implementers might wish to define clear responsibilities for each actor prior to implementation, ensure early engagement with new providers, offer mechanisms/forums for sharing learning, generate evidence and provide advice on incentive payments, and prioritise public and professional awareness of the programme.

Background There is debate about how best to increase access to psychological therapy and deliver mental healthcare effectively and efficiently at a national level. One trend is the increased use of the telephone to deliver therapy. However, there is the potential to disadvantage certain patient groups and/or impact on uptake of help. This study aims to answer three questions: (i) Which factors are associated with being offered an assessment by telephone? (ii) Which factors are associated with attendance at assessment? and (iii) What is the impact of an assessment by telephone on subsequent treatment appointment? Methods Routine outcome data was provided by seven UK Improving Access to Psychological Therapy services. The analysis sample comprised 49,923 patients who referred to 615 general practices in 2017. Multilevel modelling, including service and GP practice as random factors, was used to answer the three research questions. Results The offer of an initial assessment by telephone was strongly associated with local service configuration. Patient self-referral, a shorter wait, greater age and lower deprivation were associated with attendance at assessment and subsequent treatment session. Telephone mode assessment had no impact on the uptake of the assessment but may influence the uptake of further treatment if this was also by telephone. The practitioner carrying out the assessment had a significant effect on subsequent treatment uptake. Conclusion Offering telephone assessments does not have a negative impact on uptake of assessment and services may benefit by facilitating and integrating telephone assessments into their systems. The COVID-19 pandemic has accelerated the use of telephone and other remote means of delivery, and results from this study can inform services to consider how best to re-configure post-pandemic.

The Network Episode Model (NEM) is a well utilised model conceptualising how social networks, valuable resources which can positively impact wellbeing and functional outcomes, are responsive to the needs of people with physical and mental health difficulties. Children of parents with severe and enduring mental illness (COPMI) are impacted by these illnesses through the intersecting roles of kin relation, informal carer, and dependent. However, it is not clear that social networks effectively respond in kind to the child’s episodic need. We draw upon qualitative data to propose a new multi-factorial conceptual model (COPMI-NEM), triangulating parental mental illness, child’s developmental stage and social ties to theorise how social networks do respond and adapt to children’s needs.The model illustrates how networks are typically flexible and responsive to visible age-related needs, but less reactive to more obscured needs. Successful network navigation and negotiation of support relies on multiple factors including the child’s ability to successfully activate social ties and the availability of formal networks. We propose a new theoretically and empirically informed NEM model also available for testing, refinement and validation in other young carer populations exposed to episodic parental health needs. Findings from this study could be used to generate network informed interventions for this and comparable populations.

Background Conducting research can be time consuming, difficult and challenging. Guidance and pragmatic advice focussing on randomised controlled trial conduct are available but do not necessarily constitute comprehensive guidance. A successful trial is one that recruits to time and target and collects high-quality data within the originally agreed budget. Standardised trial management tools have outlined key project management elements for a successful trial as a method of ensuring good practice in research trials: initiation, planning, execution, monitoring and closure. Lessons are also frequently learnt during the development and conduct of trials but rarely shared for the benefit of others. For the wider research team, the key focus will always be on the execution and delivery of a study. The aim of this study was to evaluate the acceptability of clinical trials management methods, focussing on study execution and monitoring, as implemented in the National Institute for Health Research Health Technology Assessment Programme-funded Obsessive Compulsive Treatment Efficacy Trial (OCTET). Methods Workshops, questionnaires and semi-structured interviews were used to explore acceptability of trial management methods with members of the OCTET Trial research team. Nine members participated in the focus group, 10 completed a questionnaire and 20 were interviewed as part of qualitative work for the main OCTET study. Data was collected and analysed using thematic analysis. Results Six key themes were identified: support; communication; processes; resources; training and ethos. Clear and open communication, enthusiasm and accessibility of the trial managers and chief investigator were consistently noted as an important facet of the successful running of the trial. Clear resources and training materials were also found to be crucial in helping staff to work within the trial setting. Constructive suggestions were also made for improvement of these resources; for example, including both checklists and flowcharts within trial processes. Conclusion Organisation, openness and positivity are crucial for executing a trial successfully, whilst clear and focussed processes and resources are essential in monitoring and controlling the trial progress. Although derived from a single study, these findings are likely to be applicable to the successful conduct of all trials. Trial managers should consider developing these elements when setting up a study. Trial registration Clinical Trial Registry, ID: ISRCTN73535163 . Registered prospectively on 5 April 2011.

Background The implementation of new and complex interventions in mental health settings can be challenging. This paper explores the use of a Theory of Change (ToC) for intervention design and evaluation to increase the likelihood of complex interventions being effective, sustainable, and scalable. Our intervention was developed to enhance the quality of psychological interventions delivered by telephone in primary care mental health services. Methods A ToC represents how our designed quality improvement intervention targeting changes at service, practitioner, and patient levels was expected to improve engagement in, and the quality of, telephone-delivered psychological therapies. The intervention was evaluated following implementation in a feasibility study within three NHS Talking Therapies services through a qualitative research design incorporating semi-structured interviews and a focus group with key stakeholders (patients, practitioners, and service leads) ( N  = 15). Data were analysed using the Consolidated Framework for Implementation Research (CFIR) and the ToC was examined and modified accordingly following the findings. Results CFIR analysis highlighted a set of challenges encountered during the implementation of our service quality improvement telephone intervention that appeared to have weakened the contribution to the change mechanisms set out by the initial ToC. Findings informed changes to the intervention and refinement of the ToC and are expected to increase the likelihood of successful future implementation in a randomised controlled trial. Conclusions Four key recommendations that could help to optimise implementation of a complex intervention involving different key stakeholder groups in any setting were identified. These include: 1-developing a good understanding of the intervention and its value among those receiving the intervention; 2-maximising engagement from key stakeholders; 3-ensuring clear planning and communication of implementation goals; and 4-encouraging the use of strategies to monitor implementation progress.

Background Previous research has shown that our perceptions about illness are important determinants of how we respond and adjust to health threats. To examine whether illness perceptions affect illness responses in OCD (e.g. help-seeking), this study aimed to develop and test the psychometric properties of a new OCD-specific tool to assess illness perceptions, the illness perceptions questionnaire for OCD (IPQ-O). Methods A cross-sectional questionnaire-based design was used. Following adaptation of the IPQ-R based on qualitative interviews with people with OCD, adults (age ≥ 16) with OCD completed the IPQ-O (online or postal), alongside measures of depression, anxiety, OCD severity, attitudes to seeking mental health services and behaviours (e.g. treatment seeking intentions). A sub-sample re-completed the IPQ-O after two-weeks to obtain test-retest reliability. Factor analysis was used to derive the IPQ-O factor structure; internal consistency of subscales was calculated. Convergent validity was explored. Results Three hundred forty-eight people with OCD completed the IPQ-O. After factor analysis, seven main sub-scales and four cause sub-scales were identified, explaining 45.5 and 41.6% of the variance after extraction and rotation respectively. Three sub-scales from the original IPQ-R were validated; other dimensions differed from original IPQ-R sub-scales. The new ‘spectrum’ sub-scale measures the strength of the view that OCD is a trait that presents to varying extents within the general population. The IPQ-O demonstrated internal consistency, test re-test reliability (Kendall’s tau = .51–.75) and convergent validity. Illness perceptions were associated with important aspects of adjustment (depression, anxiety) and condition management (receipt of treatment, plans to seek help). In particular, emerging data showed that those who had not received medication for OCD endorsed stronger spectrum beliefs. Though longitudinal study is needed to verify the direction of this association, this raises the question of whether spectrum beliefs deter people with OCD from using pharmacological treatments. Conclusions The IPQ-O provides a valuable tool for subsequent testing of whether illness perceptions drive outcomes as proposed by the CSM. If perceptions are found to drive adjustment and behaviour, therapists could elicit and subsequently challenge perceptions that have negative effects on adjustment and coping, as part of psychological therapy.

Background Remote delivery of psychological interventions to meet growing demand has been increasing worldwide. Telephone-delivered psychological treatment has been shown to be equally effective and as satisfactory to patients as face-to-face treatment. Despite robust research evidence, however, obstacles remain to the acceptance of telephone-delivered treatment in practice. This study aimed to explore those issues using a phenomenological approach from a patient perspective to identify areas for change in current provision through the use of theoretically based acceptability and behaviour change frameworks. Methods Twenty-eight semi-structured interviews with patients experiencing symptoms of common mental health problems, waiting, receiving or having recently received telephone-delivered psychological treatment via the UK National Health Service’s Improving Access to Psychological Therapies (IAPT) programme. Interviews were recorded, transcribed verbatim, and analysed using the Theoretical Domains Framework (TDF) and Theoretical Framework of Acceptability (TFA). Results The majority of data clustered within five key domains of the TDF (knowledge, skills, cognitive and interpersonal, environmental context and resources, beliefs about capabilities, beliefs about consequences) and mapped to all constructs of the TFA (affective attitude, ethicality, intervention coherence, self-efficacy, burden, opportunity costs, and perceived effectiveness). Themes highlighted that early stages of treatment can be affected by lack of patient knowledge and understanding, reservations about treatment efficacy, and practical obstacles such as absent non-verbal communication, which is deemed important in the development of therapeutic alliance. Yet post-treatment, patients can reflect more positively, and report gaining benefit from treatment. However, despite this, many patients say that if they were to return for future treatment, they would choose to see a practitioner face-to-face. Conclusions Using a combination of theoretically underpinned models has allowed the identification of key targets for change. Addressing knowledge deficits to shift attitudes, highlighting the merits of telephone delivered treatment and addressing skills and practical issues may increase acceptability of, and engagement with, telephone-delivered treatment.

Background Contemporary health policy is shifting towards remotely delivered care. A growing need to provide effective and accessible services, with maximal population reach has stimulated demand for flexible and efficient service models. The implementation of evidence-based practice has been slow, leaving many services ill equipped to respond to requests for non-face-to-face delivery. To address this translation gap, and provide empirically derived evidence to support large-scale practice change, our study aimed to explore practitioners’ perspectives of the factors that enhance the delivery of a NICE-recommended psychological intervention, i.e. guided self-help by telephone (GSH-T), in routine care. We used the Theoretical Domains Framework (TDF) to analyse our data, identify essential behaviour change processes and encourage the successful implementation of remote working in clinical practice. Method Thirty-four psychological wellbeing practitioners (PWPs) from the UK NHS Improving Access to Psychological Therapies (IAPT) services were interviewed. Data were first analysed inductively, with codes cross-matched deductively to the TDF. Results Analysis identified barriers to the delivery, engagement and implementation of GSH-T, within eight domains from the TDF: (i) Deficits in practitioner knowledge, (ii) Sub-optimal practitioner telephone skills, (iii) Practitioners’ lack of beliefs in telephone capabilities and self-confidence, (iv) Practitioners’ negative beliefs about consequences, (v) Negative emotions, (vi) Professional role expectations (vii) Negative social influences, and (viii) Challenges in the environmental context and resources. A degree of interdependence was observed between the TDF domains, such that improvements in one domain were often reported to confer secondary advantages in another. Conclusions Multiple TDF domains emerge as relevant to improve delivery of GSH-T; and these domains are theoretically and practically interlinked. A multicomponent approach is recommended to facilitate the shift from in-person to telephone-based service delivery models, and prompt behaviour change at practitioner, patient and service levels. At a minimum, the development of practitioners’ telephone skills, an increase in clients’ awareness of telephone-based treatment, dilution of negative preconceptions about telephone treatment, and robust service level guidance and standards for implementation are required. This is the first study that provides clear direction on how to improve telephone delivery and optimise implementation, aligning with current mental health policy and service improvement.
