Study Notes
Research Questions, Problems, and Hypotheses
- Research problems are enigmatic, perplexing, or troubling conditions.
- Problem statements articulate the research problem and the rationale for the study.
- Statements of purpose summarize the overall goal of the study.
- Research questions are queries that the researcher wants answered to address the research problem, often one central question.
- Hypotheses are predictions about relationships among variables – viewed as educated guesses.
Types of Theories
- Classical theory systematically explains relationships among phenomena.
- Descriptive theory thoroughly describes a phenomenon based on rich observations.
- Grand theory attempts to explain large aspects of human experiences.
- Middle-range theory focuses on a specific aspect of human experience.
Models
- Conceptual models deal with abstractions, assembled in a coherent scheme; represent a more loosely structured attempt to explain phenomena than theories.
- Schematic models visually represent relationships among phenomena and used in both quantitative and qualitative research.
Types of Theoretical Frameworks and Models
- Grand theory examples include Watson's Theory of Human Caring, Peplau's Theory of Interpersonal Relations, and Leiniger's Transcultural Nursing Theory.
- Middle-range theory examples include Beck's Theory of Postpartum Depression, Mishel's Uncertainty in Illness Theory, and Pender's Health Promotion Model.
Commonalities of Theories and Conceptual Models
- Use concepts as building blocks.
- Require conceptual definitions of key concepts.
- Can be represented in schematic models.
- Are developed inductively.
- Cannot be proven – they are supported to varying degrees.
- Can generate hypotheses and serve as stimuli for research.
Conceptual Models of Nursing
- Formal explanations of nursing practice.
- Four central concepts: human beings, environment, health, and nursing.
Other Models Used by Nurse Researchers
- Bandura's Social Cognitive Theory (self-efficacy): Explains human behavior using the concepts of self-efficacy, outcome expectations, and incentives.
- Prochaska's Transtheoretical Model (stages of change): Used in healthcare settings.
- Becker's Health Belief Model: Used in healthcare settings.
- Ajzen's Theory of Planned Behavior: Used in healthcare settings.
Examples of Key Constructs From Shared Theories
- Self-efficacy (how much control I have over my own life) – a concept from Social Cognitive Theory.
- Stages of change – a concept from the Transtheoretical Model.
- Behavioral intentions – a concept from the Theory of Planned Behavior.
Theories in Qualitative Research
- Substantive theory is used to understand target phenomena.
- Grounded theory focuses on establishing three core principles, involving human action, meaning, and interpretive processes.
- Ethnography explores the cultural aspects of a situation, using ideational and materialistic theories.
- Phenomenology examines the philosophical underpinnings of human experience.
Theoretical Underpinning of Grounded Theory
- Grounded theory focuses on three core principles: human action towards things, derived meanings from human interactions, and meanings modified through interpretive process.
Critiquing Research Problems, Questions, and Hypotheses
- Evaluating the clarity and communication of the research problem.
- Assessing the significance and compatibility of the problem with the nursing field and research paradigms.
- Evaluating the suitability of the statement of purpose and research questions to the research inquiry.
The Use of Theories or Models in Quantitative Research
- Testing a theory through deducing hypotheses to be tested.
- Testing a theory-based intervention.
- Using a theory or model for organization or interpretation.
- Fitting a problem into theory after the fact (Not recommended)
Additional Guidelines for Critiquing Frameworks
- Evaluating whether a report describes a conceptual framework.
- Assessing how well major features of the theory/model are described for understanding.
- Evaluating whether the theory/model is appropriate for the research problem.
- Determining whether the theory/model is used to generate hypotheses.
- Checking if the concepts & intervention components are consistent with the theory.
- Evaluating if the framework guides the study methods.
- Assessing if findings are interpreted within the framework.
Quantitative Studies
- Concepts typically well-developed with established methods; researchers use these or develop new measurement tools to support the understanding of the need.
Qualitative Studies
- Study undertaken when a rich understanding of a poorly understood phenomenon is required.
Research Problems and Questions
- Problems must be broad enough to include central concerns, but narrow enough to guide study design.
Components of a Problem Statement
- Identify the problem (why?).
- Provide background on the problem's nature.
- Give the scope of the problem and affected populations.
- Outline consequences of not addressing the problem.
- Identify knowledge gaps.
- Propose a solution for how the study will contribute.
Statement of Purpose: Quantitative Studies
- Identify key variables (independent and dependent variables).
- Note possible relationships between variables (cause and effect, or correlation).
- Indicate the target population.
- State the nature of the research inquiry (e.g., testing, comparing, evaluating).
Statement of Purpose: Qualitative Studies
- Identify central phenomena.
- Suggest relevant research traditions (e.g., grounded theory, ethnography).
- Indicate the relevant group, community, or setting of interest.
- Suggest the nature of the inquiry (e.g., to describe, to discover, to explore).
Hypotheses
- Statements of expected answer to a research question.
- Typically involve two or more variables (relationship between independent and dependent variables).
Hypotheses and Proof
- Hypotheses are never proved or disproved, but supported or rejected by the data,
- They represent probabilistic inferences.
Directional vs Non-directional hypotheses
- Directional hypothesis: Specifies the expected direction of the relationship between variables.
- Non-directional hypothesis: Predicts the existence of a relationship without specifying its direction.
Research vs Null hypotheses
- Research hypothesis: States the actual prediction of relationships.
- Null hypothesis: Expresses the absence of a relationship (used for statistical testing).
Sources of Research Problems:
- Clinical experience, nursing literature, social issues.
- Suggestions from external sources like national organizations or funders, change in political tide
