Description

This academic lecture by Dr. Wilbroad Mutale, presented for a 6th-year research methods course, provides an overview of key epidemiological study designs. It distinguishes between observational and experimental studies, detailing specific designs within each category. The material covers case reports/series, case-control studies (retrospective), cohort studies (prospective), and population studies, explaining their logic, advantages, disadvantages, and measures of effect like odds ratios. It then explains experimental studies, focusing on clinical trials, the importance of control groups, randomization, and blinding (single, double, triple) to minimize bias and establish causality. This resource is essential for tertiary-level students in medical, public health, and health sciences programs at the degree or postgraduate level, offering a foundational understanding of research methodology for designing and critically appraising studies. Download these notes to strengthen your knowledge of comparative study designs and their application in health research.
