This presentation introduces critical appraisal and how to evaluate evidence and websites. Critical appraisal involves a balanced assessment of the strengths and weaknesses of research by considering the research process, results, and both quantitative and qualitative aspects. It is important to critically appraise research to determine the validity, reliability, and applicability. When evaluating evidence, the presenter outlines 10 steps to appraise purpose, background, methods, population, participants, data, analysis, interpretations, conclusions, and enjoyment. Key criteria for evaluating websites include source, authority, objectivity, currency, and coverage.
