PPIE (Public Involvement and Engagement)
Involvement and Engagement are interrelated and sometimes are interchangeably used.
Involvement means that activities and research are carried out ‘with’ or ‘by’ members of the public, rather than ‘to’, ‘about’ or ‘for’ them. Members of the public are actively involved in the development, running and management of research projects or activities. Definition from: National Institute for Health and Care Research (NIHR).
Engagement describes the myriad of ways in which the activity and benefits of an organisation or research can be shared with the public. Engagement is by definition a two-way process, involving interaction and listening, with the goal of generating mutual benefit. Definition from: National Co-ordinating Centre for Public Engagement (NCCPE).
PPublic
Can cover a broad range of people, including the general public and patients but also other professionals working across different sectors.
PPublic Advisory Group
A public advisory group or panel is a dedicated group of public members who support and advise research projects or governance within an organisation. The PEDRI public advisory group (PAG) provides guidance and support to PEDRI to ensure public voice is embedded in all our work.
PPublic Contributor(s)
Members of the public who are involved in research and projects are sometimes referred to as public contributors, as they help contribute to the overall piece of work. They are also sometimes referred to as Public Partners. PEDRI has several public contributors supporting our work across our workstreams. See ‘Public Advisory Group’.
PPublic Good
Refers to activity which is motivated by its benefit to society, rather than private profit. This work often aims to provide evidence for public policies, services or decisions to ultimately improve lives. Definition from: ADR UK (Administrative Data Research UK)
PPublic Representative(s)
A representative is expected to speak on behalf of a larger group of people. Public representatives consider a wider range of people’s views, rather than just their own perspective. Definition adapted from: National Institute for Health and Care Research (NIHR)
RResearch
The term research means different things to different people but is essentially about finding out new knowledge that could lead to changes to treatments, policies or care. The definition used by the Department of Health is: “The attempt to derive generalisable new knowledge by addressing clearly defined questions with systematic and rigorous methods.” Definition from: National Institute for Health and Care Research (NIHR)
RResearcher
Researchers are the people who do the research. They may do research for a living and be based in a university, hospital or other institution and/or they may be a service user or carer. Definition from: National Institute for Health and Care Research (NIHR)

Also known as data safe havens or Trusted Research Environments (TREs). Definition from: NHS England
SService User
A service user is someone who uses or has used health and/or social care services because of illness or disability. Some people do not like this term because they feel it has negative connotations. Definition from: National Institute for Health and Care Research (NIHR)
SStatistical analysis
Statistical analysis uses a set of mathematical rules to analyse quantitative data. It can help researchers decide what data means. For example, statistical analysis can assess whether any difference seen between two groups of people (for example between the groups of people in a clinical trial) is likely to be a reliable finding or simply due to chance. Definition from: National Institute for Health and Care Research (NIHR)
SStatistics
A set of numbers (quantitative data) obtained through research. For example, the average age of a group of people or the number of people using a service. Definition from: National Institute for Health and Care Research (NIHR)
