F, there has been limited OSHA jurisdiction excluding farmworkers and domestic household workers with weak or no regulations; there are also barreirs to participation in OSHA enforcement process.
Why might we prefer observational over experimental designs?

What is the main difference between observational and experimental study designs?
Experimental study- investigator determines through a controlled process the exposure for each individual or community, then follows them over time to detect the effects of exposure Observational Studies- Investigator observes rather than determines each individual's exposure status.
How strong is the association (between disease/sickness and habits) Is there a clear temporality?
Exposure to agent or risk factor must precede the development of the disease, and the disease should follow exposure within predictable time frame.

Understand the Health Belief Model and its use in health promotion. Be able to outline some of its key concepts.
Model developed to explain and predict health-related behaviors, particularly in regard to the uptake of health services Perceived Severity -Individuals who perceive a given health problem as serious are more likely to engage in behaviors to prevent the health problem from occurring (or reduce its severity) Perceived Susceptibility -Individuals who perceive that they are susceptible to a particular health problem will engage in behaviors to reduce their risk of developing the health problem. Individuals with low perceived susceptibility may deny that they are at risk for contracting a particular illness. Others may acknowledge the possibility that they could develop the illness, but believe it is unlikely. Individuals who believe they are at low risk of developing an illness are more likely to engage in unhealthy, or risky, behaviors. Individuals who perceive a high risk that they will be personally affected by a particular health problem are more likely to engage in behaviors to decrease their risk of developing the condition. Perceived Benefits -Individual's assessment of the value or efficacy of engaging in a health-promoting behavior to decrease risk of disease. If an individual believes that a particular action will reduce susceptibility to a health problem or decrease its seriousness, then he or she is likely to engage in that behavior regardless of objective facts regarding the effectiveness of the action. Perceived Barriers -The perceived benefits must outweigh the perceived barriers in order for behavior change to occur Modifying Variables -Demographic, psychosocial, and structural variables can affect perceptions of health-related behaviors Modifying variables affect health-related behaviors indirectly by affecting perceived seriousness, susceptibility, benefits, and barriers Cues to Action -A cue, or trigger, is necessary for prompting engagement in health-promoting behaviors A reminder postcard from a dentist, the illness of a friend or family member, and product health warning labels Self-efficacy -An individual's perception of his or her competence to successfully perform a behavior -Confidence in one's ability to effect change in outcomes (i.e., self-efficacy) was a key component of health behavior change
