Week Three Lecture – Research Planning

  • Overview of Lecture Topics

    • Introduction to literature sorting and synthesis, a critical skill in organizing and interpreting research findings effectively.

    • Aims:

      • Better understanding of structuring literature found through research to facilitate clearer insights and informed conclusions.

      • Preparation of synthesis tables for literature review that assist in summarizing data for analysis, enabling easier comparisons across studies, and supporting evidence-based practice by providing a clear visual representation of various findings.

  • Acknowledgment of Country

    • Recognition of the Ngunnawal people as traditional custodians of Canberra land, emphasizing respect for their culture, history, and contributions to the region's life. This acknowledgment aims to foster a more inclusive learning environment and raises awareness of Indigenous culture among students.

  • Lecture Questions

    • How to organize literature effectively to promote a systematic approach when conducting research?

    • What does literature synthesis look like, and how can it be applied in creating robust literature reviews?

  • Pre-Lecture Suggestions

    • Students are advised to watch three mini-lectures prior to the main lecture to build foundational knowledge.

      • Available on Canvas, labeled Week Three:

      • Lecture 1: Levels of Evidence, discussing the hierarchy of research designs and their implications for practice.

      • Lecture 2: Information Sources and Building Research Questions, focusing on effective strategies for identifying relevant literature and structuring research questions.

      • Lecture 3: Searching the Literature, which provides techniques for efficient literature search strategies to maximize retrieval success.

  • Current Status of Literature Search

    • After developing a research question and implementing a thorough search strategy, students evaluate retrieved articles with a critical eye towards relevance and quality.

    • Aim to narrow down articles to between 15-20 for thorough critique and synthesis, ensuring a focused and manageable body of literature for analysis.

  • Organizing Literature

    • Importance of comprehensive reading, which goes beyond abstracts and AI summaries to fully understand the context, methodologies, and outcomes of research studies.

    • Suggested tools for organization:

      • Excel Spreadsheet or other customizable formats that allow for a tailored approach to organizing literature in a way that suits individual research needs.

  • Suggested Headings for Literature Organization

    • Article Title, Author Name, and Date to provide clear identification of sources.

    • Research Question (optional), when relevant, to connect articles directly to research objectives.

    • Type of Research (Qualitative/Quantitative) to categorize methodologies.

    • Study Design (e.g., Randomized Controlled Trial, Cohort Study) to assess the robustness of findings.

    • Levels of Evidence (to be elaborated in the next slide), showcasing the reliability of various studies in the context of clinical recommendations.

    • Quality Assessment (optional) using suggested tools mentioned to provide context on the credibility of research findings.

    • JBI assessment tools recommended for qualitative assessment, ensuring effective evaluation of non-quantitative studies.

    • Methods Used (Participant Recruitment) to understand how participants were chosen.

    • Results Summary to highlight key findings succinctly.

    • Critical Analysis Points to encourage deeper evaluation of each study's contributions and limitations.

  • Detailed Steps for Article Evaluation

    • Start with Aim of the Study

      • Usually found at the end of the introduction; assess whether the research question was answered clearly and logically.

    • Methods Assessment

      • Determine if the study is qualitative or quantitative to understand the type of analysis.

      • Evaluate study design based on NHMRC levels (see next slide) to judge the strength of evidence presented.

      • Importance of assessing study bias:

        • Understand selection bias, recall bias, attrition bias, and their potential influences on study outcomes.

    • Level of Evidence Pyramid

      • The NHMRC guidelines are instrumental for understanding credibility:

        • Bottom: Expert opinion (low level of evidence)

        • Higher Levels: Cohort studies, Randomized Controlled Trials, each providing progressively robust evidence.

        • Top: Systematic Review and Meta-analysis (highest level of evidence), which integrate findings from multiple studies.

    • Making Judgements on Credibility

      • Evaluate bias and its impact on conclusions drawn, ensuring rigorous critical thinking is applied throughout the analysis.

  • Understanding Outcome Measures

    • Clearly described outcome measures in the methods section are crucial.

    • Assess if outcomes align with research interests to evaluate relevance.

    • Review statistical analysis approach; ensure it is appropriate for the study type and effectively measures impact.

    • Examine results critically for authenticity in relation to research questions; this includes scrutinizing how well the research addressed the stated hypotheses.

    • Focus on confidence intervals, not solely p-values, for clinical relevance, understanding that both metrics provide insight into study findings.

  • Example Study Overview

    • Randomized controlled trial on gluteal tendinopathy with three arms:

      • Physiotherapy/Education, Cortisone Injections, and Wait-and-See strategies.

    • Points of Evaluation

      • Check for inclusion criteria and participant demographics to assess representativeness.

      • Analyze primary and secondary outcomes, and validate the statistical analysis conducted—ensuring methods are appropriate and well-directed.

      • Example: Primary outcome of change in pain intensity is measured at various time points, illustrating the effectiveness of interventions.

  • Article Summarization in Table Format

    • Organize findings from literature reviews in a summarized table format for clarity and ease of reference:

      • Include key elements such as Author, research type, study design, level of evidence, quality assessment, research questions, methods, results, and critical analysis points.

    • The importance of maintaining a consistent format throughout to promote efficient data retrieval and easier comparisons among studies.

  • Final Notes

    • Synthesis tables are essential for clarity in literature reviews, aiding in the distillation of complex information.

    • Suggest simplified presentation of tables in assignments for effective critical analysis and presentation of findings.

    • Emphasize the benefit of summarizing literature to facilitate easier writing and synthesis later, which can reduce cognitive load during the actual writing process.

    • Encourage students to integrate draft tables and notes into assignment planning, fostering an organized approach to research evaluation and review.
