CHAPTER 3

Research design and methodology

3.1

INTRODUCTION

This chapter covers the research design and methodology, including sampling, population, establishing rigour during and after data collection, ethical considerations and data analysis. 3.2

RESEARCH DESIGN

Burns and Grove (2003:195) define a research design as “a blueprint for conducting a study with maximum control over factors that may interfere with the validity of the findings”.
Parahoo (1997:142) describes a research design as “a plan that describes how, when and where data are to be collected and analysed”. Polit et al (2001:167) define a research design as “the researcher’s overall for answering the research question or testing the research hypothesis”.

This study focuses on the opinion of nurses on pain in patients that suffer from dementia.
The research approach is non-experimental, qualitative, exploratory-descriptive and contextual. 3.2.1 Non-experimental research

According to Polit et al (2001:178), non-experimental research is used in studies whose purpose is description and where it is unethical to manipulate the independent variable.
Non-experimental research is suitable for the study of people in nursing for several reasons. First, due to ethical considerations manipulation of the human variable is not acceptable because of the potential for physical or mental harm to the participants.
Secondly, human characteristics are inherently not subject to experimental manipulation,

such as health beliefs and opinions. Thirdly, research constraints such as time, personnel and the type of participants, make non-experimental research more feasible. Lastly, qualitative studies do not interfere with the natural behaviour of participants being studied; the type of research question would not be appropriate for an experimental research (Polit et al 2001:178). In this study data were collected without introducing any treatment.

    Research is primarily an investigation. Researchers and scientists gather data, facts, and knowledge to help better understand phenomenon, events and people. Through research, analysis, investigations, and experimentation, we gain a better understanding of our world. As I skimmed the text to find a definition, I found the word research several times on several of the pages in the first chapter. Research is fundamental to any scientific enterprise and statistics is no exception.…

    As both The Abbey and PAINAD scales are subjective tools, where assessment is something that is based on personal opinion or knowledge, the lack of training and guidance provided could cause results to be interpreted differently depending on who was undertaking the assessment (Buffum et al., 2007). It was recognised that results were also dependent on prior knowledge of the individual themselves. A clinical study undertaken by Helfand and Freeman (2009) suggested that nursing staff involved in the study found that both PAINAD and Abbey pain scales required prior knowledge of the individual. When staff undertook the assessments within an acute clinical setting it was difficult to ascertain and interpret whether a patient with dementia had pain, if they were…

    Pain Assessment

    • 1176 Words
    • 5 Pages

    The majority of the nurses that were surveyed utilized the verbal pain assessment tool at almost 90%. Ninety-two percent of the registered nurses assessed pain on each patient in their care, and the notifications to the physician of uncontrolled pain is at a 90% rate. The conclusion that can be drawn from this study is that the different populations of patients were assessed, was and could be done so by different assessment tools pertinent to that patient. The findings of this particular study have significant implications for registered nurses in using evidence-based practice to adequately treat patient’s pain. The study suggested that for nurses to properly treat the pain, the populations at hand should be taken into consideration. In learning how different populations perceive pain, nurses were then able to use evidence pain practice to adequately control patient’s…

    The term research is defined as an active, thorough and systematic process of enquiry that is aimed at discovering, interpreting and revising facts. It is defined by Lancaster (1975) as “a planned, systematic search for information, for the purpose of increasing the total of man’s knowledge”. It is described by Polit and Beck (2004) as being systematic enquiry. They write that “the ultimate goal of research is to develop, refine and expand a body of knowledge”. The importance of carrying out research is to further knowledge, enhance understanding and to assess effectiveness. The word research itself derives from the French language and when translated literally means “to investigate thoroughly”.…

    As per American Geriatrics Society, 2002 (pS205), a chronic pain is defined as a painful experience that continues for a longer period of time that may or may not be associated with a recognizable disease process.
