Nursing Research Paradigms & Assumptions Paradigm A worldview or general view on the complexities of the real world. Assumption The response to a philosophical question that can represent a paradigm. Ontologic What is the nature of reality? Naturalistic Paradigm Emphasizes focus on the entirety of phenomena, the whole experience. Focuses on under-standing ideas from the informants’ experience & understanding. Uses inductive (general to specific) reasoning, narrative information & qualitative analysis. Positivist Paradigm Emphasizes the rational & scientific. Believes (assumes) reality is out there to be studied Refers to a basic principle that is believed true with verification. Uses deductive (specific to general) reasoning, quantitative information & statistical analysis. Epistemologic What is the relationship between the researcher & that being studied? Axiologic What is the role of value in the inquiry? Methodologic How should the researcher obtain knowledge?
Concepts & definitions • Why are they important? Concepts: “In studies that fail to articulate a conceptual framework, it may be difficult to figure out what the researcher thought was “going on’ – and why.” Definitions: “When researchers fail to clarify the conceptual underpinnings of their research variables, it becomes difficult to integrate research findings.” Polit & Beck, 8th edition, page 143.
Quantitative Research • Research Problem • Purpose of the research is to “solve” the problem or contribute to solution • Originates with researchers’ interests or experience • Consider the problem’s: • Significance • Researchability • Feasibility of the problem
Quantitative Research • Research Problem • Express problem & what is it that needs fixing • Includes: • Problem statement: found early in the report • 1st sentence after abstract • Research question: research will specifically answer this ? • Hypothesis: • prediction about the relationship between 2 or more variables; prediction of expected outcomes • Clear, concise present tense wording • Types (inductive, deductive, simple, complex, directional, non-directional, scientific/research, null) Pollit & Beck pgs 95-100
Quantitative Research • Research Problem • Express problem & develop a rationale for research • Should describe what it is that is problematic & what needs fixing by including: • Problem identification: What is wrong with the current situation? • Background: What is the nature of the problem, the context of the situation that readers need to understand? • Problem Scope: How big a problem is it; how many people are affected? • Problem Consequences: What’s the cost of not fixing the problem? • Knowledge gaps: What info about the problem is lacking?
Quantitative Research • Statement of Purpose • Summary of the overall goal of a study • Establishes general direction of the research • Captures (usually in 1 or 2 sentences) essence of the study • Identifies key variables & possible interrelationships along with study population • Little researched topic: verbs → explore, describe • Experimental: verbs → test or evaluate • Non-experimental: verbs → examine or assess
Literature Review/Critique • Primary source: description of studies written by the research who conducted them • Secondary source: description of studies prepared by someone other than the original researcher
Flow of Literature Review 1 4a Formulate & refine primary & secondary questions Discard irrelevant or inappropriate references Ancestry approach: looking for earlier studies Descendancy approach: search forward to subsequent studies 2 3 5 4 Devise search strategy (id keywords) Search for, identify & retrieve potential primary source materials Read source materials Screen sources for relevance, & appropriateness 5a 3a Identify new references & new leads Document search decision & actions
Flow of Literature Review 5 6 7 Read source materials Critique & evaluate studies Abstract, encode information from the studies 8 Analyze, integrate information, search for themes 9 Prepare synthesis / critical summary
Writing a Literature Review • Written summary of evidence on research problem • Identify Themes: detection of patterns or regularities • Substantive: pattern, amount, consistency, persuasiveness, gaps • Theoretical: theories or frameworks used to address primary question or has most research been without a theoretical basis? • Methodologic: designs & methods used to address primary question, method strategies that have NOT been used, methodological deficiencies & strengths? • Generalizability/transferability: types of people or settings findings apply to, findings vary for gender, ethnicity, area or age • Historical: trends over time?, evidence getting better? Period most research conducted? • Researcher: person/discipline/specialty/nationality conducting research, developed within a systematic program of research?
Writing a Literature Review • Organize: • Outline: leads to an understandable flow of information • Goal: keep review logical & lead to conclusion about the state of evidence on the topic • Content is an objective summary of: • what has been studied Reveals current state of knowledge on a topic • how adequate & dependable the studies are • gaps that exist in the research • contribution your study will make
Research Theory & Concepts What makes research high quality? High levels of • Conceptual integration. This occurs when the • Research question is appropriate for methods & strategies • Question is consistent w/ existing body of evidence • Conceptual rationale is plausible for • expected outcomes • testing hypothesis • designing interventions
Theory • Traditional Theory: an abstract simplification offering an systematic explanation about how phenomena (events) are interrelated • Represents 2 or more concepts that are related & explained deductively • Includes: proposition, postulate, premise, axiom, law, principle • Concepts: basic building blocks making up a theory • Grand Theory: describe large segments of the human experience • Middle-Range Theory: more restricted in scope, focusing on a narrow range of experience
Theory • Descriptive theory: Broad description of 1 quantitative phenomena • Empirically driven to describe a specific dimension or characteristic of an individual, group, situation, or event by summarizing commonalities found in discrete observations Fawcett (1999, pg 15)
