Scenario I
Scenario I is based on fabricated data inspired by the following study:
Coriddi, M., Angelos, T., Nadeau, M., Bennett, M. & Taylor, A. (2013) . Analysis of satisfaction and well-being in the short follow-up from breast augmentation using the BREAST-Q, a validated survey instrument. Aesthetic Surgery Journal, 33 (2) , 245-251.
Breast Augmentation Satisfaction
The authors of this study used the BREAST-Q survey to assess satisfaction following breast augmentation surgery. They administered the survey to 155 patients before and after they underwent breast augmentation surgery and found a significant increase in psychosocial well-being and sexual well-being. A significant positive relationship was also found between overall satisfaction and breast appearance (r = .80) . Interestingly, there was a significant decrease in physical well-being following surgery. The results of the study suggest that breast augmentation has a positive effect on women.
-(Scenario I) What is the best reason for why the authors probably selected the BREAST-Q to measure satisfaction associated with breast augmentation surgery?

A) satisfaction is not something easy to measure using observational methods
B) the researchers wanted to find a causal relationship between breast augmentation surgery and satisfaction
C) they were interested in obtaining information from just a few people
D) they wanted to assess satisfaction with breast augmentation surgery qualitatively
