AN ABSTRACT OF THE DISSERTATION OF VICTOR NOLLEN WHITE, for the Doctor of Philosophy degree in Health Education, presented On November 14, 2014, at Southern Illinois University Carbondale. Title: THE USE OF THE EXPANDED HEALTH BELIEF MODEL (EHBM) TO EVALAUTE OSTEOPOROSIS ATTITUDES, KNOWLEDGE, BELIEFS AND SELF-EFFICACY OF NEZ PERCE TRIBAL AND NON NEZ PERCE TRIBAL MEMBERS IN NEZ PERCE COUNTY, IDAHO. Major Professor: Dr. Dhitinut Ratnapradipa According to the State of Idaho, the National Osteoporosis Foundation, and the U.S. Department of Health and Human Services, osteoporosis is a public health concern nationally among non-Native American (NNA) and Native American (NA) populations. The purpose of this research project is to obtain written survey data on osteoporosis attitudes, knowledge, beliefs, and self-efficacy among male and female members of the Nez Perce Tribe (Nimiipuu) and non-Tribal members, aged 18 and over via voluntary completion of a written survey questionnaire based on the expanded health belief model (EHBM). The study was conducted in Nez Perce County, ID. The research involved determining whether or not there is a statistically significant difference in osteoporosis attitudes, knowledge, beliefs and self-efficacy among males and females, aged 18 and over Nez Perce Tribal members as compared to Non-Tribal members in Nez Perce County, ID. Non-Nez Perce tribal members are individuals whom are 1) Native Americans who are not members of the Nez Perce Tribe and 2) all Non-Native Americans in the research study. Exercise self-efficacy and gender seem to be the most significant variables showing evidence against the null hypotheses and in favor of the research hypothesis (Null Hypothesis: H0: Native American=Non-Native American. Research Hypothesis: H1: Native American ≠ Non-Native American). Age also shows evidence against the null hypothesis and in favor of the research hypothesis, but not as strongly as exercise and gender. Seriousness of osteoporosis was the most concern to all respondents and female Native Americans perceived the greatest barrier to preventing osteoporosis was being unable to access dietary calcium on a regular basis.
