social epidemiology

Suppose you want to examine if abstinence self-efficacy affects smoking cessation (this is your research question). “Abstinence self-efficacy” is defined as confidence in ones ability to abstain from (i.e., stop) smoking. You cannot randomly assign study participants to different abstinence self-efficacy levels, so only observational studies can be conducted to examine this research question. In a 350-500 word essay, address the following questions:

How would you measure the key variables (i.e., smoking efficacy and smoking cessation)?
Are there other variables you would like to include in your study to control for confounding?
how would you design this study to draw the study participants and perform a comparison? (Pick one from cross-sectional, case-control, and cohort study design). What are the key features of this study design?
What are the strengths and weaknesses of your study design?
Your write-up should be written in essay format rather than bullet points. Grading on the write-up is based on both the content and the quality of the writing.
