Service user involvement in research can range from the extremes of being the subject, to being the initiator or investigator, of a research study. The activity of the professional researcher can also range from being the person undertaking the research, to being a partner with, or mentor to, service users. This broad scope of levels of involvement is reflected in the contributions in this book, both in the research experiences reported and in the writing of the chapters themselves. With contributions coming from a range of service areas including learning disabilities, cancer care, older people and mental illness, chapters look at important research issues such as: strategies for working in true partnership avoiding ‘tokenism’ involving service users at all stages of the research process communication and terminology involving service users of different ages and experience training needs of professionals and service users problems surrounding ‘payment’ for service users other ethical and practical issues. This book is invaluable reading for researchers in health and social care from academic, professional and service user backgrounds.
