NURS 4610: Translating Evidence for Nursing Practice: Analytical Cross-Sectional Studies

What is an Analytical Cross-Sectional Study?

An analytical cross-sectional study is a type of quantitative, non-experimental research design. These studies seek to "gather data from a group of subjects at only one point in time" (Schmidt & Brown, 2019, p. 206).  The purpose is to measure the association between an exposure and a disease, condition or outcome within a defined population.  Cross-sectional studies often utilize surveys or questionnaires to gather data from participants (Schmidt & Brown, 2019, pp. 206-207).

PRO TIPS: Analytical Cross-Sectional Study Checklist

Each JBI Checklist provides tips and guidance on what to look for to answer each question.  These tips begin on page 4. 

Below are some additional Frequently Asked Questions about the Analytical Cross-Sectional Studies Checklist that have been asked students in previous semesters. 

Frequently Asked Question Response
In regards to Question 5, what exactly is a confounding factor? A confounder or confounding factor/confounding variable is often referred to as a third variable that could potentially impact the study's results. See the definition in the Cochrane Glossary. Confounding factors/variables or confounders may be listed in the study's limitations section or within the study's main results section. 
For Question 6, how can I tell whether strategies were used to deal with the confounding factors in the study? Check for multivariate analysis or regression analysis in the study's data analysis/statistical analysis section. See the definition in the Cochrane Glossary
