Methodological Rigour (methodological + rigour)
Selected AbstractsMethodological rigour within a qualitative frameworkJOURNAL OF ADVANCED NURSING, Issue 4 2004Gerard A. Tobin BSc MSc RGN RMN RCNT RNT Aim., This paper discusses the literature on establishing rigour in research studies. It describes the methodological trinity of reliability, validity and generalization and explores some of the issues relating to establishing rigour in naturalistic inquiry. Background., Those working within the naturalistic paradigm have questioned the issue of using validity, reliability and generalizability to demonstrate robustness of qualitative research. Triangulation has been used to demonstrate confirmability and completeness and has been one means of ensuring acceptability across paradigms. Emerging criteria such as goodness and trustworthiness can be used to evaluate the robustness of naturalistic inquiry. Discussion., It is argued that the transference of terms across paradigms is inappropriate; however, if we reject the concepts of validity and reliability, we reject the concept of rigour. Rejection of rigour undermines acceptance of qualitative research as a systematic process that can contribute to the advancement of knowledge. Emerging criteria for demonstrating robustness in qualitative inquiry, such as authenticity, trustworthiness and goodness, need to be considered. Goodness, when not seen as a separate construct but as an integral and embedded component of the research process, should be useful in assuring quality of the entire study. Triangulation is a tried and tested means of offering completeness, particularly in mixed-method research. When multiple types of triangulation are used appropriately as the ,triangulation state of mind', they approach the concept of crystallization, which allows for infinite variety of angles of approach. Conclusion., Qualitative researchers need to be explicit about how and why they choose specific legitimizing criteria in ensuring the robustness of their inquiries. A shift from a position of fundamentalism to a more pluralistic approach as a means of legitimizing naturalistic inquiry is advocated. [source] Is multidisciplinary learning effective among those caring for people with diabetes?DIABETIC MEDICINE, Issue 10 2002N. Munro Abstract The role of multi-professional learning for those providing clinical services to people with diabetes has yet to be defined. Several assumptions are generally made about education in the context of multi-professional settings. It is argued that different professions learning together could potentially improve professional relationships, collaborative working practices and ultimately standards of care. Greater respect and honesty may emerge from a team approach to learning with a commensurate reduction in professional antagonism. Personal and professional confidence is reportedly enhanced through close contact with other professionals during team-based learning exercises. We have examined current evidence to support multidisciplinary learning in the context of medical education generally as well as in diabetes education. Previous investigation of available literature by Cochrane reviewers, aimed at identifying studies of interprofessional education interventions, yielded a total of 1042 articles, none of which met the stated inclusion criteria. Searches involving more recent publications failed to reveal more robust evidence. Despite a large body of literature on the evaluation of interprofessional education, studies generally lacked the methodological rigour needed to understand the impact of interprofessional education on professional practice and/or health care outcomes. Nevertheless, planners continue to advocate, and endorse, joint training between different groups of workers (including nurses, doctors and those in professions allied to medicine) with the objective of producing an integrated workforce of multidisciplinary teams. Whilst the concept of multi-professional learning has strong appeal, it is necessary for those responsible for educating health care professionals to demonstrate its superiority over separate learning experiences. [source] Schematic representation of case study research designsJOURNAL OF ADVANCED NURSING, Issue 4 2007John P. Rosenberg Abstract Title.,Schematic representation of case study research designs Aim., The paper is a report of a study to demonstrate how the use of schematics can provide procedural clarity and promote rigour in the conduct of case study research. Background., Case study research is a methodologically flexible approach to research design that focuses on a particular case , whether an individual, a collective or a phenomenon of interest. It is known as the ,study of the particular' for its thorough investigation of particular, real-life situations and is gaining increased attention in nursing and social research. However, the methodological flexibility it offers can leave the novice researcher uncertain of suitable procedural steps required to ensure methodological rigour. Method., This article provides a real example of a case study research design that utilizes schematic representation drawn from a doctoral study of the integration of health promotion principles and practices into a palliative care organization. Discussion., The issues discussed are: (1) the definition and application of case study research design; (2) the application of schematics in research; (3) the procedural steps and their contribution to the maintenance of rigour; and (4) the benefits and risks of schematics in case study research. Conclusion., The inclusion of visual representations of design with accompanying explanatory text is recommended in reporting case study research methods. [source] ,Best research practice': in pursuit of methodological rigourJOURNAL OF ADVANCED NURSING, Issue 3 2001Frances Maggs-Rapport BA MPhil CertEd FRSA ,Best research practice': in pursuit of methodological rigour Rationale.,This paper is based on the rationale that misuse of methodological notions in research publications lays research studies open to criticism and dismissal. Aim.,In search of ,best research practice', this paper aims to examine the different qualities of four major qualitative methodologies: ethnography, descriptive phenomenology, interpretative phenomenology/hermeneutics and critical social theory. Design.,The study presents a critical overview of methodological decision-making, illustrating the sorts of issues researchers must consider in order to justify to the readership and to themselves the employment of a particular methodology. This is presented alongside a general overview of qualitative research and a précis of each of the major qualitative methodologies. The paper describes the methodologies, salient features, and examines methodological similarities and differences. The paper concludes by examining the need for methodological rigour within the framework of the National Health Service (NHS) Executive's drive for evidence-based practice in health care. Recommendations.,It is hoped that the paper will stimulate a deeper exploration of methodological rigour in future research publications. [source] Methodological issues in grounded theoryJOURNAL OF ADVANCED NURSING, Issue 6 2000John R. Cutcliffe RMN RGN BSc(Hons) Methodological issues in grounded theory Examination of the qualitative methodological literature shows that there appear to be conflicting opinions and unresolved issues regarding the nature and process of grounded theory. Researchers proposing to utilize this method would therefore be wise to consider these conflicting opinions. This paper therefore identifies and attempts to address four key issues, namely, sampling, creativity and reflexivity, the use of literature, and precision within grounded theory. The following recommendations are made. When utilizing a grounded method researchers need to consider their research question, clarify what level of theory is likely to be induced from their study, and then decide when they intend to access and introduce the second body of literature. They should acknowledge that in the early stages of data collection, some purposeful sampling appears to occur. In their search for conceptually dense theory, grounded theory researchers may wish to free themselves from the constraints that limit their use of creativity and tacit knowledge. Furthermore, the interests of researchers might be served by attention to issues of precision including, avoiding method slurring, ensuring theoretical coding occurs, and using predominantly one method of grounded theory while explaining and describing any deviation away from this chosen method. Such mindfulness and the resulting methodological rigour is likely to increase the overall quality of the inquiry and enhance the credibility of the findings. [source] Action research, change and methodological rigourJOURNAL OF NURSING MANAGEMENT, Issue 4 2000T. G. Badger BSC (HONS) Aim To critically examine concepts of methodological rigour in action research and consider how these affect its capacity to enable change. Key issues Action research is potentially attractive to managers of nursing because it is a problem-focused approach. As action research is identified as a continuum of definitions and philosophies rather than a single approach, caution is expressed that the search for definition may obscure the underlying process of change. Issues of reliability and validity are explored, suggesting that concern for methodological rigour may limit the potential for change and improvement in practice. Ethical issues in action research are considered identifying areas for tension between researchers, managers and practitioners. Some examples of action research in nursing are discussed. Conclusion Action research may be valuable in individual practitioners' development or in fostering collaboration between academe and practice. However the demands for methodological rigour in research limit its effectiveness as a strategy for managing change. [source] Statistical issues in the assessment of health outcomes in children: a methodological reviewJOURNAL OF THE ROYAL STATISTICAL SOCIETY: SERIES A (STATISTICS IN SOCIETY), Issue 4 2009Gillian A. Lancaster Summary., The lack of outcome measures that are validated for use on children limits the effectiveness and generalizability of paediatric health care interventions. Statistical epidemiology is a broad concept encompassing a wide range of useful techniques for use in child health outcome assessment and development. However, the range of techniques that are available is often confusing and prohibits their adoption. In the paper an overview of methodology is provided within the paediatric context. It is demonstrated that in many cases assessment can be performed relatively straightforwardly by using standard statistical techniques, although sometimes more sophisticated techniques are required. Examples of both physiological and questionnaire-based outcomes are given. The usefulness of these techniques is highlighted for achieving specific objectives and ultimately for achieving methodological rigour in clinical outcome studies that are performed in the paediatric population. [source] Fauna habitat modelling and mapping: A review and case study in the Lower Hunter Central Coast region of NSWAUSTRAL ECOLOGY, Issue 7 2005BRENDAN A. WINTLE Abstract Habitat models are now broadly used in conservation planning on public lands. If implemented correctly, habitat modelling is a transparent and repeatable technique for describing and mapping biodiversity values, and its application in peri-urban and agricultural landscape planning is likely to expand rapidly. Conservation planning in such landscapes must be robust to the scrutiny that arises when biodiversity constraints are placed on developers and private landholders. A standardized modelling and model evaluation method based on widely accepted techniques will improve the robustness of conservation plans. We review current habitat modelling and model evaluation methods and provide a habitat modelling case study in the New South Wales central coast region that we hope will serve as a methodological template for conservation planners. We make recommendations on modelling methods that are appropriate when presence-absence and presence-only survey data are available and provide methodological details and a website with data and training material for modellers. Our aim is to provide practical guidelines that preserve methodological rigour and result in defendable habitat models and maps. The case study was undertaken in a rapidly developing area with substantial biodiversity values under urbanization pressure. Habitat maps for seven priority fauna species were developed using logistic regression models of species-habitat relationships and a bootstrapping methodology was used to evaluate model predictions. The modelled species were the koala, tiger quoll, squirrel glider, yellow-bellied glider, masked owl, powerful owl and sooty owl. Models ranked sites adequately in terms of habitat suitability and provided predictions of sufficient reliability for the purpose of identifying preliminary conservation priority areas. However, they are subject to multiple uncertainties and should not be viewed as a completely accurate representation of the distribution of species habitat. We recommend the use of model prediction in an adaptive framework whereby models are iteratively updated and refined as new data become available.

[source] Prescribed stimulant use by Western Australians with Attention Deficit Hyperactivity Disorder (ADHD): does amount dispensed exceed the expected authorised use?AUSTRALIAN AND NEW ZEALAND JOURNAL OF PUBLIC HEALTH, Issue 6 2007Janine Calver Abstract Objective: To investigate to what extent Western Australian (WA) patients with Attention Deficit Hyperactivity Disorder (ADHD) received prescribed stimulants in excess of their notified dose from WA pharmacies in 2004 (termed ,discrepancy'). Design and data sources: Analysis of administrative data about all people aged two years and older who were prescribed stimulants for the treatment of ADHD in WA, and had at least one stimulant prescription dispensed from a WA pharmacy during the period 1 January to 31 December 2004. Outcome measures: Discrepancies were identified using minimum and maximum estimation methods (MinDE, MaxDE). We calculated for both methods the discrepancy prevalence by age and sex and annual surplus of stimulant accrued by age. Results: Of the 15,190 ADHD patients who comprised the study population, 5.4% to 19.0% received stimulants surplus to requirement in 2004, with peak prevalences in 6-8 year-olds (MaxDE 20.1%) and 25-34 year-olds (MaxDE 27.6%; MinDE 10.5%). The amount of stimulant dispensed surplus to requirement was highly skewed, with median annual values that ranged from one to 4.1 standard bottles (100 tablets) of dexamphetamine 5 mg for the MinDE and MaxDE methods, respectively. Conclusion: It is difficult to definitively estimate to what extent WA ADHD patients accrued excess stimulant medication using routine administrative data. Improvements to the WA Stimulant Regulatory Guidelines are recommended in the interests of patient safety, public transparency, methodological rigour and encouraging good prescribing practices.
