The Personal Social Services Research Unit (PSSRU) (@PSSRU_LSE) is one of the leading social care research groups in the world, and has contributed in many ways to the development of national and local policies and frontline practice in the UK and elsewhere. Its reputation for high-quality, robust research has encouraged many national and local policy-makers, commissioners and service providers to request its support in generating evidence to inform discussions and decisions. Since its establishment in 1974, PSSRU has had considerable impact on national social care policy in the UK and in a number of other countries. PSSRU has also established itself as the leading European group on mental health economics and policy, and has an excellent worldwide reputation for its work in this field. LSE Works is a series of public lectures, that will showcase some of the latest research by LSE's academic departments and research centres. In each session, LSE academics will present key research findings, demonstrating where appropriate the implications of their studies for public policy.
