The nature of expert psychiatric nurse practice: A grounded theory study

• This study examines what psychiatric nurses regard as the nature of expert psychiatric nurse practice. • The study focuses on the beliefs and principles of psychiatric nurses currently working within a psychiatric unit. • Using grounded theory methodology, data were coded and analysed, producing an integrated framework of expert psychiatric nurse practice comprised of four core variables: 'attitudes/philosophy', 'knowledge', 'skills' and 'roles'. • It is suggested that the nature of expert psychiatric practice is an evolutionary concept and that as this practice develops the integrated theory presented will need to develop in parallel. © 1997 Blackwell Science Ltd.
