Reliability and Validity Assignment.

Week 2 discussion Discussion Part One Shelby is a 32-year-old mother of two, who has smoked 1 pack-per-day for the last 15 years, and who comes to see you today for her yearly well-woman exam in your family practice clinic. She has a family history, in a single paternal grandmother of breast cancer at age 52. She also has a history of an abnormal cervical cancer screening three years ago requiring colposcopy. Given her history please consider the following: Choose one screening test that might be considered either now or in the next few years of Shelby’s care. Define the test, its positive predictive value, reliability and validity. Discussion Part Two Upon the course of your history you find out that Shelby has a great aunt on her mother’s side who died of ‘some woman cancer in her stomach’ and an uncle on her father’s side who died of pancreatic cancer. Her mother and older sisters are all in good health. Does this information change your recommendations for screening? Why or why not? Discussion Part Three Please provide a summary of the case or information you have discussed this week.

© homeworkjoy.comReliability and validity are concepts used to evaluate the quality of research. They indicate how well a method, technique or test measures something.Reliability is about the consistency of a measure, andvalidity is about the accuracy of a measure.Overview of Reliability and Validity
For research and testing, there are subtle differences. Reliability implies consistency: if you take the ACT five times, you should get roughly the same results every time. A test is valid if it measures what it’s supposed to. Tests that are valid arealso reliable.
