Biography

Biography

Charley is a research fellow at the National Institute for Health and Care Research South West Peninsula Applied Research Collaborative (PenARC) Mental Health Research Initiative. This role involves enabling mental health research across the South West of England, including working with mental health trusts, GP practices and voluntary sector providers. Her methodological expertise includes Realist evaluation, IPA, systematic reviews, and researcher in residence models.  In this role Charley has worked with both statutory and non-statutory mental health service providers to design and undertake realist researcher-in-residence evaluations, and to empower knowledge mobilisation across mental health service providers in the South-West.  She has trained and supervised university and NHS staff in utilising Realist evaluation and researcher in residence approaches, focusing on evaluation of services designed to reduce gaps in mental health care and/or implement the Community Mental Health Framework.   
Charley chairs the South West Researcher in Residence Peer Group, which provides peer support and advice to researchers in residence as they embed and work in other organisations.
Charley is the university lead for the South West Community Mental Health Knowledge Mobilisation Network.

Research interests

Charley is a mental health researcher with a particular interest in research that improves the day to day well being and quality of life for people with mental health problems. Methodologically speaking, Charley is a mixed methods researcher, with particular interest and experience in Realist evaluation and researcher-in-residence approaches. She also has experience in randomised controlled trials, systematic reviewing, ripple effects mapping and IPA. Charley is skilled in liaising with different NHS bodies to improve engagement with and appropriateness of mental health research. Where appropriate Charley draws on her own experiences of mental health problems, and experiences as a carer of someone with a mental health problem.

Other research

Previous to her current role Charley was working as researcher in residence with Somerset NHS Foundation Trust evaluating their work as an early implementer (https://openmentalhealth.org.uk/) site for the new community mental health framework (https://www.england.nhs.uk/mental-health/adults/cmhs/). This involved liaising with NHS staff, service users, voluntary sector staff, primary care staff and social care staff to understand the new systems put in place to date, and agree an appropriate and useful evaluation topic. Charley led a Realist evaluation of the extent and impact of cultural changes within the Trust as part of the transformation.
Prior to this Charley worked on the large NIHR funded PARTNERS2 programme (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8278501/). This programme looked to develop and test a new model of care for people with diagnoses of severe mental illness which utilises both collaborative care and coaching from a Recovery orientated perspective. During her time on this project Charley contributed to multiple workstreams: qualitative Realist process evaluation of fidelity, change and refinements to model; cluster randomised control effectiveness trial; Cochrane systematic review of collaborative care for severe mental illness; sub-study investigating the role of researcher rapport building and disclosure in conversations with research participants with diagnoses of severe mental illness. Results papers from this project are currently in press as of September 2021.
Charley's PhD focuses on the experience of coping with tiredness related side effects of antipsychotics, such as sedation, sleepiness, fatigue, and increased sleep. This includes a mixed methods systematic scoping review of the literature relating to prevalence, impact and management of these side effects, and a qualitative (IPA) exploration of the coping mechanisms deployed by those experiencing tiredness related side effects.
