New York, McGraw-Hill Education, 2015. Medical education research commonly uses measurement instruments with items that are rated on Likert-type scales, whereby the respondent is asked to assess their level of agreement with a given statement. Simulation-based assessment to reliably identify key resident performance attributes. What is the conceptual framework being used to approach the study? In quantitative research, the findings will reflect the reliability and validity (psychometric characteristics) of the measured outcomes or dependent variables (such as changes in knowledge, skills, or attitudes) used to assess the effectiveness of the medical education intervention (the independent variable of interest). In qualitative research, you may create open-ended research questions, while in quantitative analysis, you can only create closed questions such as questions that are answerable with multiple choices. What is the effect size? Qualitative research is, in some cases, instrumental to developing an understanding of a phenomenon as a basis for quantitative research. Analyzing and interpreting data from Likert-type scales. The statement of study intent is arguably the most important element of framing the study because it makes the research purpose explicit.2  Consider the following example: This study aimed to test the hypothesis that the introduction of the BASIC Examination was associated with an accelerated knowledge acquisition during residency training, as measured by increments in annual ITE scores.15, This statement of study intent succinctly identifies several key study elements including the population (anesthesiology residents), the intervention/independent variable (introduction of the BASIC Examination), the outcome/dependent variable (knowledge acquisition, as measure by in In-training Examination [ITE] scores), and the hypothesized relationship between the independent and dependent variable (the authors hypothesize a positive correlation between the BASIC examination and the speed of knowledge acquisition).6,14. For example, you can measure the temperature or heart rate. Method and reporting quality in health professions education research: A systematic review. One aspect of the MERSQI that deserves special mention is the section on evaluating outcomes based on Kirkpatrick’s widely recognized hierarchy of reaction, learning, behavior, and results (table 5; fig. This site uses cookies. While medical education shares many characteristics with other biomedical fields, substantial particularities exist. Below is the result of the poll that was taken for a sample size of 50 people from different areas and age groups: Since there is a different count of respondents for each of the ratings, hence we need to calculate the result by us… In June 1913 the Medical Research Committee held its first meeting. Table 1 2–5  outlines these steps, which will be described in detail in the following sections. Evaluating medical education research requires specific orientation to issues related to format and content. The structured way of collection and analysis of the data which is obtained from the different sources involving the use of statistics, computational and mathematical tools in order to derive the results is known as Quantitative research. Measurement variables in quantitative research generally fall into three categories: nominal, ordinal, or interval.24  Nominal variables (sometimes called categorical variables) involve data that can be placed into discrete categories without a specific order or structure. The NOS-E includes items focusing on the representativeness of the experimental group, selection and compatibility of the control group, missing data/study retention, and blinding of outcome assessors.38,39  Additional validity evidence for NOS-E scores includes operational definitions to improve response process, excellent reliability and internal consistency, and its correlation with other measures of study quality.39  Notably, the complete NOS-E, along with its scoring rubric, can found in the article by Cook and Reed.39.

Qualitative research is commonly used in the humanities and social sciences, in subjects such as anthropology, sociology, education, health sciences, history, etc. ), Mayo Clinic College of Medicine and Science, Department of Medicine, Mayo Clinic, Rochester, Minnesota. The reported research observes the behaviour of restaurant customers, and example paragraphs are combined with instructions for logical argumentation. Single-group pre–post study designs open themselves to a myriad of threats to internal validity.20  In our hypothetical example, the improvement in residents’ intubation skills may have been due to other educational experience(s) (i.e., implementation threat) and/or improvement in manual dexterity that occurred naturally with time (i.e., maturation threat), rather than the airway curriculum. 4th edition. ). The establishment of experiment research designs, where interventions (i.e. Conceptual frameworks may take the form of theories, principles, or models that help to explain the research problem by identifying its essential variables or elements. Swanwick T: Understanding medical education: Evidence, theory and practice, 2nd edition. When evaluating a medical education research article, it is important to identify the sampling technique the researchers employed, how it might have influenced the results, and whether the results apply to the target population.24, Sampling techniques generally fall into two categories: probability- or nonprobability-based.
