Abstract Details

2010, MS, University of Cincinnati, Medicine : Biostatistics (Environmental Health).
There are many situations in research when the circumstances do not allow the subject to be interviewed about their medical, family or work history, due to their death, or being incapable of providing responses on their own. In these situations the researcher must rely on a proxy. Using the data from the Upper Midwest Health Study (UMHS), two power simulation analyses were completed to determine the appropriate sample size of proxy respondents required to maintain a power of 0.80 or higher. Results show that we can rely on the proxy responses for agreement to the subject response for demographic questions, but not for study-related questions. Additionally, the power analysis demonstrated that when the percent of disagreement between the proxy and subject responses are larger, fewer proxy respondents are required for a power of 0.80.
