    Study Notes

    Qualitative Research

    • Involves analyzing non-numeric data such as language
    • Used across disciplines like anthropology, psychology, sociology, and kinesiology
    • Also known as ethnographic, grounded theory, phenomenological research
    • Involves defining the problem, formulating questions and frameworks, collecting data, and analyzing results
    • Data collection methods include interviews, focus groups, and observations
    • Ensuring trustworthiness in research using credibility, transferability, dependability, and confirmability

    Trustworthiness in Qualitative Research

    • Credibility - accurately representing the subjects and context
    • Transferability - the ability of the findings to be applied to similar contexts
    • Dependability - consistency of the results over time and through different researchers
    • Confirmability - the validity of findings when verified by others
    • Can be supported through data quality, bias management, triangulation, and member checking

    Data Analysis in Qualitative Research

    • Step 1: Transcribe interviews
    • Step 2: Sort and categorize data
    • Step 3: Merge insights
    • Techniques include: analytic narrative, narrative vignette, use of direct quotes

    Experimental and Quasi-Experimental Research

    • Examines cause and effect relationships
    • Requires a strong theoretical framework, experimental design, proper variables, and statistical analysis
    • Criteria for causality includes:
      • Cause precedes the effect
      • Cause and effect correlate
      • No other variable can explain this correlation

    Types and Threats to Validity

    • Internal Validity: Assesses whether the treatment actually caused the observed change
    • External Validity: Assesses whether the findings can be generalized to other contexts
    • Threats to internal validity include:
      • History
      • Maturation
      • Testing effects
      • Selection biases
    • Threats to external validity include:
      • Interaction of testing with treatment,
      • Biases in participant selection

    Experimental Design Types

    • Pre-experimental: Simple designs with limited control, such as one-shot studies or one-group pretest-posttest designs
    • Experimental: Involves random assignment of participants to groups and manipulation of the independent variable
    • Quasi-experimental: Does not involve random assignment, but tracks a single participant over time

    Epidemiology

    • Examines the distribution and determinants of health outcomes in populations
    • Observational research: Examines naturally occurring differences without intervention
    • Experimental research: Tests the effects of treatments, often ethically limited

    Key Epidemiological Concepts

    • Distribution: Frequency (prevalence and incidence) and patterns (person, place, time)
    • Determinants: Factors that influence or contribute to the health outcome

    Epidemiological Study Designs

    • Cross-sectional: Compares different groups of participants at the same time
    • Cohort: Tracks a group over time to observe changes in health outcomes
    • Case-controlled: Matches participants with and without a condition to explore potential risk factors

    Correlation & Regression

    • Correlation: Examines relationships between two or more variables
    • Types of correlation: Positive or negative
    • Regression: Predicts outcomes from one or more variables
    • Simple regression: Predicts outcomes from a single predictor variable
    • Multiple regression: Uses several predictor variables to predict a complex outcome
    • Logistic regression: Used to predict binary outcomes (e.g., yes/no)

    Research Synthesis, Systematic Reviews, and Meta-Analysis

    • Purpose of Research Synthesis: Clearly defined purpose to identify and analyze existing research
    • Literature Review: Exploratory, often used to find a research purpose
    • Meta-Analysis: Analyzing data from multiple studies to answer research questions
    • Steps involved in meta-analysis:
      • Define research objectives
      • Conduct a literature search using specified databases and criteria
      • Select studies based on pre-determined inclusion and exclusion criteria
      • Evaluate and code data to extract important details
      • Calculate effect sizes for each study
      • Conduct statistical analysis to summarize the effects across studies
      • Report findings
    • Systematic Review: Summarizes research on a specific topic, often without the quantitative focus of meta-analysis
    • Steps involved in a systematic review:
      • Forming a research team
      • Registering the review protocol (e.g., PROSPERO)
      • Screening studies for eligibility
      • Including relevant studies in the review
      • Flowchart is used to visually track the steps of the review.
    • Considerations in Meta-Analysis:
      • Effect Size Coding - selecting the appropriate statistics and accounting for group differences
