Dissemination and Critical Evaluation of Published Research Peg Bottjen, MPA, MT(ASCP)SC
Objectives Upon the completion of this lecture and exercise the student will be able to: Recognize methods of research dissemination Describe the conventional format of published research Evaluate a published article according to criteria given
Purpose of Published Research Answer questions using scientific method Descriptive Correlational Causal – explain causation
Dissemination of Research Oral report Poster presentation Journal article
Format of Research Presentations Title Abstract Introduction Methods Results Discussion References
Title Concise, descriptive sentence stating the exact topic of the report. Identifies the subjects of study Variables, characteristics Followed by investigator’s name and affiliation ex. The incidence of alcoholism in health professionals as a function of work- related stress.
Abstract Short, concise paragraph describing entire report (<250 words) One or two precise sentences from each section Introduction Method Results Discussion
Introduction Background – reasons to conduct study, theoretical framework, literature review Statement of purpose – goal of study, problem statement Hypotheses – educated guess as to relationship between variables Research question – specific question studied Past - - Present
Method Subjects – who they are, how obtained Materials – equipment, apparatus, instruments used, quality of instruments Procedures – how study conducted, what subjects did or what was done to them
Reliability - Precision The test or assessment measures the same thing every time and results in the same answer every time. Test-retest – correlates 1 st to 2 nd Inter-observer – between different observers Internal consistency – between items measured
Validity - Accuracy The test or assessment measures what it claims to measure. Sensitivity - % true positive Specificity - % true negative Test ResultDisease PresentDisease Absent +True +False + -False -True -
Validity Predictive value Ability of a measurement to predict the value of it or another test in the future (prognosis) What is predictive value of an ACT score to your grade point average in college?
Results Technical data In text In tables In figures
Discussion Non-technical interpretation of results Connect results to purpose, hypotheses, and theory Explain results Identify limitations Suggestions for further research
References List of literature discussed Sufficient detail so reader can identify and retrieve the source Journal articles, internet sources, books, newspapers, personal correspondence, and videos
Critical Evaluation of Research Goal: to be able to identify strengths and weaknesses of each component of a research report Why?
Look at sample given to you. Describe the format. Does it follow the conventional format we have described?
Title Does the title help you understand the article?
