IHR process evaluation studies

PARTNERS2 (Development and trial of primary care based collaborative care for people with serious mental illness) 2014-2019  This programme of research is developing and evaluating a model of collaborative care for people with psychosis. This involves a specialist mental health worker (known as a care partner) located in a primary care service, providing regular follow up and psycho-social support to service users, with an aim of increasing self-management, as well as co-ordinating care and providing consultation to the primary care team. Building on a structured process of programme theory development and informed by a formative evaluation at the pilot study stage, the process evaluation aims to assess the fidelity of the intervention. In particular, the process evaluation will assess how any changes in the understanding and behaviour of care partners over the duration of the trial were influenced by the training and support provided. Using multiple data sources, it also aims to achieve an indepth understanding of how the intervention does or does not work in comparison to the programme theory, and how it might be implemented in different contexts.

SkiM (Skills for weight loss and Maintenance) 2015-2018. We used intervention mapping and collaborated with local service providers to develop a programme to support long term weight loss, and then evaluated and refined the programme over two rounds of delivery. The process evaluation has involved the development and use of questionnaires to investigate the mechanisms through which the intervention is thought to act, and longitudinal interviews with participants to further elucidate facilitators, barriers and processes of change at the individual level. Mixed methods data collection from 100 participants, and from the facilitators who delivered the programme, were also used to evaluate its acceptability and feasibility, and informed changes in programme content and delivery.

REACH-HF (Rehabilitation EnAblement in Chronic Heart Failure) 2013-2018  This programme of research has designed and evaluated a 12-week health professional facilitated home-based cardiac rehabilitation programme for patients with heart failure and their caregivers. The process evaluation examined: whether the intervention was delivered as planned and any variation in delivery; what mechanisms explained any observed impact on health related quality of life; the factors associated with variation of intervention effectiveness; and if the use of a patient tracker identified changes associated with patient’s health related quality of life. We also investigated patient and caregiver views and experiences of the intervention.

GREAT (Goal-oriented cognitive Rehabilitation in Early-stage Alzheimer’s and related dementias) 2012-2017  The GREAT trial tested a cognitive rehabilitation intervention designed to improve management of everyday activities and reduce functional disability, through identifying personal goals and then applying a problem-solving approach and rehabilitative strategies. The process evaluation investigated goal-setting and the process of therapy. We examined how goals were addressed in therapy and how therapy was delivered, using individual therapy logs and accounts from a focus group completed with the therapist. We also assessed participant and carer experience of the intervention through qualitative interviews, the effectiveness of supervision and participant treatment compliance.

HeLP (Health Lifestyles Programme) 2006-2016  This study investigated whether the schools-based Healthy Lifestyles Programme positively affected eating and activity habits of children, and family behaviours, to help children maintain a healthy weight. The process evaluation examined: whether the intervention was delivered as intended in terms of both the content and the manner in which it was delivered; whether teachers, families and children engaged with the programme from across the socioeconomic spectrum; the acceptability of the programme for schools, children and families; and how children responded to different phases of the intervention.
