Didactics-Observationtal Studies

Video Transcription

Video Summary

In this video, molecular biologist Andreina Fernández discusses observational studies. She explains that these studies observe natural relationships between factors and outcomes, allowing researchers to evaluate risk factors, diagnostic tests, and treatments. Fernández discusses the classification of observational studies into descriptive (measuring once), longitudinal (measuring more than once), and analytical (with a comparison group) studies. She also explains the difference between retrospective and prospective studies. Fernández explores various types of observational studies, including case reports, case series, cross-sectional studies, case control studies, and cohort studies. She highlights the common errors and biases associated with these studies and emphasizes the importance of critical reading using the STROBE guidelines. Lastly, Fernández concludes that while observational studies have limitations, they are often the only feasible research methodology in certain situations.
