Study designs can be classified as descriptive or analytical. The analytical studies have more power, or ability to predict, than descriptive studies and therefore rank higher in the evidence based world. Descriptive studies give us a snap shot of what is happening. Surveys, case reports, cross sectional studies (using surveys) are descriptive.
Identifying the best research design to fit the question. Part 1
Evidence-based nursing is about applying the best available evidence to a specific clinical question. Different clinical questions require evidence from different research designs. No single design has precedence over another, rather the design chosen must fit the particular research question.1 Questions focused on the cause, prognosis (course), diagnosis, prevention, treatment, or economics ...
Types of Research within Qualitative and Quantitative
♦ Statement of purpose—what was studied and why.. ♦ Description of the methodology (experimental group, control group, variables, test conditions, test subjects, etc.).. ♦ Results (usually numeric in form presented in tables or graphs, often with statistical analysis).. ♦ Conclusions drawn from the results.. ♦ Footnotes, a bibliography, author credentials.
Evidence Based Practice: Study Designs & Evidence Levels
Case report / Case series: A report on a series of patients with an outcome of interest.No control group is involved. Case control study: A study which involves identifying patients who have the outcome of interest (cases) and patients without the same outcome (controls), and looking back to see if they had the exposure of interest. Cohort study: Involves identification of two groups (cohorts ...
A spotter's guide to study designs
Q1, Q2, and Q3 refer to the 3 questions outlined under "Spotting the study design.". Our first distinction is whether the study is analytic or non-analytic. A non-analytic theoretical study tries to explain and develop our understanding of processes that occur for participants. Theoretical studies are qualitative and usually are based on ...
Research Design & Methodology
Four types of qualitative research design often applied to nursing research are: Phenomenology - the study of human life experiences and how they appear in human consciousness; Grounded Theory - seeks to explain variations in social interactional and social structural problems and processes ; Ethnography - As a research process, ethnography is a comparative method for investigating patterns of ...

An introduction to different types of study design
We may approach this study by 2 longitudinal designs: Prospective: we follow the individuals in the future to know who will develop the disease. Retrospective: we look to the past to know who developed the disease (e.g. using medical records) This design is the strongest among the observational studies. For example - to find out the relative ...
