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.
