The model will help nurses planning to develop nursing interventions as it provides additional and nursing-specific guidance to the MRC (Developing and Evaluating Complex Interventions, 2008) framework for the development of complex interventions for nursing practice.

People with multiple sclerosis depend heavily upon their families and other informal carers as they receive limited support from health-care professionals or health-care services. Adopting the carer role results in a life-changing experience, which may bring rewards and challenges to the carer. This paper reviews the research addressing the experiences of carers of people with multiple sclerosis published between 2002 and 2007 building upon an earlier review. The literature suggests that carers have needs across various domains and that spouses/partners have particular needs. Much of the evidence has limited generalizibility although the geographical spread of the evidence indicates considerable consistency of need. The review describes ongoing carer needs which require supportive care and provides the basis for the development and testing of carer interventions for use by health-care professionals.

Education, support and information-giving interventions warrant further investigation across caregiver groups. A large-scale funded programme for caregiver research is required to ensure that studies are of high quality to inform service development across settings.

Enhancing inter-professional collegial relationships and improving managerial recognition of the role within nursing are key areas to be targeted to promote job satisfaction of ANPs.

New nursing researchers are faced with a smorgasbord of competing methodologies. Sometimes, they are encouraged to adopt the research paradigms beloved of their senior colleagues. This is a problem if those paradigms are no longer of contemporary methodological relevance. The aim of this paper was to provide clarity about current research paradigms. It seeks to interrogate the continuing viability of positivism as a guiding paradigm for nursing research. It does this by critically analysing the methodological literature. Five major paradigms are addressed: the positivist; the interpretivist/constructivist; the transformative; the realist; and the postpositivist. Acceptance of interpretivist, transformative or realist approaches necessarily entails wholesale rejection of positivism, while acceptance of postpositivism involves its partial rejection. Postpositivism has superseded positivism as the guiding paradigm of the scientific method. The incorporation in randomized controlled trials of postpositivist assumptions indicates that even on the methodological territory that it once claimed as its own, positivism has been rendered redundant as an appropriate paradigm for contemporary nursing research.
