Key Terms to Review (16)

Apa style: APA style is a writing format established by the American Psychological Association, primarily used for academic papers in the social sciences. It emphasizes clarity, precision, and the proper attribution of sources, ensuring that research is presented consistently and professionally. Its guidelines cover various aspects such as citation formatting, manuscript structure, and references, making it essential for literature reviews and research proposals.
Bibliography: A bibliography is a list of sources, such as books, articles, and websites, that were referenced or consulted in the creation of a work. It serves as a way to give credit to the original authors and sources of information, while also providing readers with resources for further research. A well-structured bibliography not only enhances the credibility of the work but also helps readers locate the sources used.
Chronological order: Chronological order is the arrangement of events or information in the sequence that they occurred in time. This method helps readers follow a timeline, making it easier to understand how one event leads to another, especially in literature reviews where examining the progression of research and findings is crucial.
Contextualization: Contextualization is the process of placing information, events, or concepts within their surrounding environment or framework to better understand their significance and implications. By considering the context in which data is situated, researchers can gain deeper insights into the meanings, interpretations, and cultural influences that shape human behavior and communication.
Google Scholar: Google Scholar is a freely accessible search engine that indexes the full text or metadata of scholarly literature across various formats. It provides a simple way to broadly search for scholarly articles, theses, books, conference papers, and patents, making it an essential tool for conducting comprehensive literature reviews.
Impact factor: Impact factor is a metric used to evaluate the relative importance and influence of academic journals based on the frequency with which their articles are cited in other research. This measure reflects the journal's reach and credibility within the academic community, as a higher impact factor indicates a greater level of influence and readership.
Meta-analysis: Meta-analysis is a statistical technique used to combine the results of multiple studies to identify patterns, relationships, or effects that may not be apparent in individual studies. This method enhances the understanding of a research question by synthesizing quantitative data, allowing researchers to draw more robust conclusions from a larger body of evidence. By aggregating results, meta-analysis can provide greater statistical power and improve the precision of estimates related to specific interventions or phenomena.
Narrative review: A narrative review is a comprehensive, qualitative synthesis of existing research literature that provides an overview of a specific topic or field, highlighting key findings, themes, and gaps in knowledge. This type of review allows researchers to present a cohesive story based on the collected studies, offering context and understanding rather than just a summary of the available evidence.
Peer-reviewed: Peer-reviewed refers to the process through which scholarly work, such as research articles or studies, is evaluated by experts in the same field before publication. This ensures that the research meets the standards of quality, validity, and relevance within the academic community, making it a reliable source for literature reviews and further research.
PubMed: PubMed is a free search engine primarily accessing the MEDLINE database of references and abstracts on life sciences and biomedical topics. It is a vital resource for researchers and healthcare professionals to find scientific articles, clinical studies, and reviews that contribute to the literature in health-related fields.
Qualitative Synthesis: Qualitative synthesis is a research method that involves systematically combining and interpreting qualitative data from multiple studies to develop a comprehensive understanding of a particular phenomenon. This process allows researchers to identify patterns, themes, and insights that may not be apparent in individual studies, providing a richer context for analysis and understanding.
Research Gap: A research gap is an area in a field of study that has not been sufficiently explored or addressed, highlighting the need for further investigation. Identifying these gaps is crucial for researchers to contribute new knowledge, as it informs where the existing literature falls short and what questions remain unanswered.
Synthesis of Knowledge: Synthesis of knowledge is the process of integrating diverse information, insights, and findings from various sources to form a cohesive understanding of a subject. This approach allows researchers to build upon existing literature, identify gaps in knowledge, and create a comprehensive framework that enhances the overall understanding of a specific area or issue.
Systematic review: A systematic review is a comprehensive and structured approach to reviewing existing research on a particular topic, aimed at summarizing all relevant studies and drawing conclusions based on the evidence. This method involves predefined criteria for selecting studies, a thorough search of literature, and a systematic analysis of findings to minimize bias. The goal is to provide an objective overview of what is known about the topic and to identify gaps in the existing research.
Thematic structure: Thematic structure refers to the organization of ideas or themes within a research study, guiding the overall flow and coherence of the work. It helps in identifying major themes, sub-themes, and their relationships, making it easier to understand how different elements of research are interconnected. This structure is crucial for synthesizing existing literature and framing research questions effectively.
Theoretical framework: A theoretical framework is a structured set of concepts, theories, and propositions that guides research by providing a foundation for understanding and interpreting phenomena. It helps researchers identify what to study, how to analyze data, and what conclusions can be drawn, establishing connections between theory and empirical research. By anchoring research questions in existing knowledge, it allows for a clearer articulation of the significance of the study within a broader context.
