Original Question

According to this week’s videos, which of the following is the purpose of the CDC? Conducting scientific research Evaluating evidence for intervention effectiveness Observing human experiences Providing contextual evidence Question at position 2 2 Multiple Choice 0.5 points Question at position 2 According to the CDC, what are the three types of evidence used to support public health interventions? According to the CDC, what are the three types of evidence used to support public health interventions? Scientific, anecdotal, and contextual evidence Best available research evidence, experiential evidence, and contextual evidence Internal, external, and observational evidence Empirical, theoretical, and practical evidence Question at position 3 3 Multiple Choice 0.5 points Question at position 3 How does research evidence differ from experiential and contextual evidence in the context of public health? How does research evidence differ from experiential and contextual evidence in the context of public health? Research evidence relies on personal experiences, while experiential and contextual evidence is based on scientific research. Experiential and contextual evidence are observations made under formal research setting, while research evidence relies on personal experiences. Research evidence is based on formal scientific research settings, while experiential and contextual evidence involves direct and personal access to the situation. There is no difference; all types of evidence are interchangeable. Question at position 4 4 Multiple Choice 0.5 points Question at position 4 What is the role of internal validity in assessing evidence for public health interventions? What is the role of internal validity in assessing evidence for public health interventions? Determining the likability of the evidence Ruling out other explanations for observed outcomes Establishing the applicability of evidence to specific situations Assessing the repetition of evidence Question at position 5 5 Multiple Choice 0.5 points Question at position 5 How does the strength of internal validity increase when evaluation evidence for public health interventions? How does the strength of internal validity increase when evaluation evidence for public health interventions? By increasing the repetition of observations Through the volume of evidence presented Including a control or comparison group, having multiple measurement points, and considering other influencing factors By relying on the position of authority of the observer Question at position 6 6 Multiple Choice 0.5 points Question at position 6 What does external validity in the context of public health evidence refer to? What does external validity in the context of public health evidence refer to? The reliability of evidence in multiple research settings The applicability of evidence to specific situations The likability of the evidence by the general public The volume of evidence available for a particular observation Question at position 7 7 Multiple Choice 0.5 points Question at position 7 Why is external validity important when evaluating evidence for public health interventions? Why is external validity important when evaluating evidence for public health interventions? It determines the repetition of observations It establishes the volume of evidence required It assesses the applicability of findings to specific situations It confirms the position of authority of the observer Question at position 8 8 Multiple Choice 0.5 points Question at position 8 What cautions should be considered when assessing the validity of evidence in public health? What cautions should be considered when assessing the validity of evidence in public health? Repetition, volume, internal validity, and position of authority Repetition, volume, position of authority, and likability Position of authority, scientific research, and control groups Experiential evidence, contextual evidence, and likability of the observer
