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. 2010-08-09 English text University of Cincinnati / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ucin1274195305 http://rave.ohiolink.edu/etdc/view?acc_num=ucin1274195305 unrestricted This thesis or dissertation is protected by copyright: some rights reserved.
