    Study Notes

    Evidence-Informed Practice (EIP)

    • EIP is a triad: best available research evidence, professional/clinical expertise, and client values/individualized needs.
    • More reliable research evidence leads to more confident clinical decisions.
    • Evidence alone isn't sufficient for clinical decisions.
    • Following EIP standards improves treatment effectiveness, insurance plan support, professional standardization, and reputation.

    Quantitative vs. Qualitative Methods

    • Quantitative methods assume a single, measurable reality and linear cause-and-effect. Researchers manipulate variables and control the environment; focus on ruling out other explanations. Use statistics to show low probability of chance, aiming for reproducible outcomes.
    • Qualitative methods accept multiple interpretations of reality; not reliant on a single reality or linear cause-and-effect. Natural observation is prioritized, with the observer being part of the process. Data in these studies is often collected via interviews, direct observation, and documents.

    Descriptive vs. Explanatory Studies

    • Descriptive studies describe a group/sample without exploring beyond it. They often form hypotheses, even though they lack strong evidence and controls. Provide detail for refining explanatory studies. Examples include case studies, case series, correlation studies, and qualitative studies.
    • Explanatory studies attempt generalized statements about a population. These studies often test a hypothesis to see if an intervention helps a population. They create stronger cause-and-effect evidence than descriptive studies and are divided into observational and experimental approaches.

    Observational Explanatory Studies

    • Prospective, longitudinal, observational studies, observe a group (cohort) over time to examine relationships between treatment and outcomes. Outcomes haven't yet occurred, and time spans are often long.
    • Pros: strong observational evidence of relationships (between treatments/risk factors and outcomes).
    • Cons: time-consuming and expensive; high rate of participant attrition.

    Experimental Explanatory Studies

    • A practitioner may determine a hypothesis and follow eligibility criteria plus methods to collect and assess patients' outcomes (example of an experimental case series).
    • Limitations compared to Before/After with Control: weaker evidence due to the lack of a control group, potentially overestimating treatment effects; and data subjectivity and optimistic patient responses.

    Descriptive Study

    • Case studies often form a basis for hypotheses.
    • Case series represent similar cases, often identifying new phenomena.
    • Anecdotes are weak evidence compared to studies; insufficient rationale, specific details, and exploratory nature.
    • Correlation studies analyze population surveys with existing data, showing associations (not causation).

    Research Article Components

    • Abstract: Summaries background, purpose, design, methods, results, conclusion, and implications.
    • Introduction: Importance, research questions, and literature review.
    • Methods: Study procedures that allow for replications by other scientists.
    • Results: Qualitative or quantitative analysis (without supporting or dismissing a hypothesis).
    • Conclusion/Discussion: Interpretation of research results; often with cited support for claims.
    • References: Sources consulted when writing research article.

    Hypothesis and Variables

    • Hypothesis: testable prediction about how things work. Often includes independent (variable being changed) and dependent variables (variables being measured).
    • Null hypothesis: assumes no relationship—often a starting point for research.
    • Independent variable: cause or influencer.
    • Dependent variable: effect; what is measured.
    • Confounding variable: affects the dependent but isn't the independent variable.
    • Controlled variable: kept constant.

    Experimental Designs

    • Between-subjects designs: different participants in each group.
    • Within-subjects designs: same participants in each group.
    • Mixed designs: combine both between and within-subject components.
