Can Ratings Of Item Location Enhance Statistical Item Parameter Estimation? Extending The Feasibility Of Unfolding Irt Models, Michael Mckenna
Dissertations
Research and development of modern psychometric methods such as item response theory have drastically changed the way we understand and carry out the measurement of psychological constructs. Despite this, there has been relatively little adoption by psychological researchers to incorporate these methods into their research. While multiple explanations are surely valid, one oft stated reason is the large sample size requirements of these methods. The sample size requirements of item response theory are needed so that effective estimation of item parameters can be carried out. In an attempt to make these modern measurement methods more accessible and feasible to psychological …

Healthcare Use Self-Efficacy In Adults Who Are Homeless, Jared Ian Israel
Dissertations
The physical and mental health care needs of homeless adults are extensive. However, these needs regularly go unmet. Healthcare use behavior is complex and involves a range of obstacles.

While current theory supports this notion and research has confirmed the role of self-efficacy in health behavior generally, a validated measure of healthcare use self-efficacy has not previously existed. The aim of this study was to develop and validate the Healthcare Use Self-Efficacy List (HUSEL) in …
Development And Validation Of A Measure Of Perceived Life Significance, Rachel Hibberd
Development And Validation Of A Measure Of Perceived Life Significance, Rachel Hibberd
Dissertations
Theoretical and empirical approaches to the study of meaning in bereavement suggest a distinction between meaning as sense-making, or the integration of the loss into a coherent and positive set of beliefs about world and self, and meaning as life significance, or the perception that some aspect of one's life experience “matters” in the wake of loss. Although several authors have pointed to the importance of life significance in grief recovery, currently no psychometrically valid measure exists. The present study examined the reliability and validity of a new measure: the Perceived Life Significance Scale (PLSS). The PLSS total score, as …
