Patient and public involvement activities bring 'lay participants' and their accounts of lived experiences to the centre of health service development and delivery. For individuals, these accounts can provide an important resource, offering a sense of control and an opportunity to re-frame past events. Furthermore, as involvement activities and the use of personal accounts have become more prominent, it is timely to examine the involvement process from the perspective of the 'lay participants'. Hence, the aim of this study is to explore how people become involved and how they construct the accounts of their lived experience. We analyse the stories of people with lived mental illness or caring experiences, who have become experts by experience (n = 13). We argue that becoming an expert by experience can help to re-contextualise past experiences and support the rediscovery of skills and expertise, leading experts by experience to construct both professionalised and politicised identities. The process has the potential to enforce narratives that portray illness experiences as motivators for social action and change. Additionally, we claim that the stories experts by experience share with health services and the public are not 'lay accounts' or ad hoc tales, but accounts constructed to serve specific purposes.

Accessible summary What is known on the subject? According to estimates more than half of adult mental health service users are parents, but their experiences are largely lacking from research literature. Parental mental illness can often be viewed from a risk perspective. Parents with mental illness and their families have unmet support needs. What this paper adds to existing knowledge? Parents with mental illness want acknowledgement that they can be able and responsible. Many parents adopt an expert by experience identity. Fathers can feel their parental role is not recognized and mothers express fears of being judged if they discuss their illness. What are the implications for practice? Adult mental health services need to recognize and support parental role of service users. Joint care planning and family oriented care should be promoted. Professionals should take advantage of the knowledge of these parents and they could be more actively engaged in service development. Abstract IntroductionParental mental illness is often viewed from a risk perspective. Despite this, being a parent can be both valuable and motivating. Research literature lacks the perspective of mothers and fathers, who have experienced mental illness. AimThis study explores how parents with mental illness construct their identities as mothers and fathers and their experiences with health and social care services. MethodThree focus groups with 19 participants were conducted in Finland and Scotland. Methods of discourse analysis have been used in to analyse the interview data. ResultsAdult service users want their parenting role recognized and supported. Parents have knowledge and skills which can be utilized and many have adopted an expert by experience identity. DiscussionBeing able to see oneself as a ‘good’ parent can be challenging but important. Parents may require support, but want to be included in the planning of their care. Services could make more use of the knowledge and skills parents and families have, and joint working could lessen parents’ anxieties. Implications for practiceMental health practitioners are in a key position in providing more family centred, resource focused care. Service user expertise should be acknowledged in clinical practice.

Health policies and strategies promote the involvement of people with illness experiences in service development and production, integrating them into settings that have traditionally been domains of health professionals. In this study, we focus on the perspectives of people with personal illness experiences and explore how they justify involvement, position themselves as legitimate actors and forge collaborative relationships with health professionals. We have used discourse analysis in analysing individual interviews conducted with peer support workers and experts by experience (n = 17) who currently work in Finnish health services. The interviewees utilised discourses of empowerment, efficiency and patient-centeredness, aligning themselves with the justifications constructed by patient movements additionally to those found in current health policies. Both groups wanted to retain critical distance from professionals in order to voice criticisms of current care practices, yet they also frequently aligned themselves with professionals in order to gain legitimacy for their involvement. They adopted professional traits that moved them further from being lay participants sharing personal experiences and adopted an expert position. Although national-level policies provided backing and legitimacy for involvement, the lack of local-level guidance could hinder the practical implementation and make involvement largely dependent of professionals' discretion.

Involving patients and the public in healthcare decision-making is on the policy agenda in several countries. The aim of our study was to describe and analyse the development of patient and public involvement from a policy perspective. We argue that the language of health policies can influence both the aims and the development of involvement methods. In this study health policy documents, which have guided the development of patient and public involvement in Finland have been analysed using methods of Membership Categorisation Analysis. This has enabled us to explore how health policy documents categorise patients and the wider public in relation to involvement and orientate the involvement activities in which people are able to participate. Different set of abilities, expectations, responsibilities and opportunities is attached to the categories of patient, risk group, service user, customer and expert. Health policy documents often equate involvement with choice making by service users and customers; or as involvement in service development by experts. In both of these cases, involvement is depicted as an individual activity that requires personal responsibility and specialist knowledge. Although involvement opportunities have overall increased, they are primarily available to people that are "participation ready" and able to adopt roles promoted in policies. Health policy documents produce one interpretation of involvement, nevertheless it is important that diverse groups of patients, the public and health professionals participate in the discussion and express their views, which may differ from those of policy makers.

The growing prominence of patient and public involvement in health services has led to the increased use of experiential knowledge alongside medical and professional knowledge bases. Third sector organisations, which position themselves as representatives of collective patient groups, have established channels to communicate experiential knowledge to health services. However, organisations may interpret and communicate experiential knowledge in different ways, and due to a lack of inherent authority, it can be dismissed by health professionals. Thus, drawing on individual interviews with organisation representatives, we explore the definitions and uses of as well as the ‘filters’ placed upon experiential knowledge. The analysis suggests that whilst experiential knowledge is seen as all-encompassing, practical and transformative, the organisations need to engage in actions that can tame experiential knowledge and try to balance between ensuring that the critical and authentic elements of experiential knowledge were not lost whilst retaining a position as collaborators in health care development processes.
