But about half of those who begin therapy drop out prematurely, and only about half of those who complete therapy experience significant improvements. Here issues of efficacy measurement and the potential role of personality differences to better guide and assess treatment are explored. It is hoped this knowledge could lead to increased success rates. In terms of outcome measurement, the use and psychometric properties of the Outcome Questionnaire-45 (OQ-45), a popular, brief measure of psychological functioning and change, are assessed. Factor structure is tested in clinical (Study 1) and student (Study 2) samples. Alternative scoring models test whether dimensions of personality drive responses. Using bi-level models, including a total score factor, fit of the intended structure and three- and four-factor personality models was similar. A seven- factor problems model provided the best fit. About half the variance in OQ-45 scores was accounted for by a Big Six personality inventory. The best items for assessing personality attributes in OQ-45 data are noted. Secondly, the relation between personality attributes and clinical presentation and outcomes is explored. Self-report scores on personality attributes predict virtually every iv life outcome and are highly associated with clinical presentation. Such attributes surely also play a role in treatment, but this association has not been widely studied. In Study 3 the relation of personality attributes to presentation, usage, and outcome is tested in a Couples and Family Therapy clinic sample (N = 222). Neuroticism was strongly associated with initial OQ-45 score, as were other scales (except Openness) to a lesser degree. Being older, more educated, and married predicted attending more sessions, and being older, female, and higher income predicted termination success. Personality scales did not play a role in either outcome. Honesty/Propriety and Neuroticism were, however, associated with steeper decrease in OQ-45 scores over time. v CURRICULUM VITAE NAME OF AUTHOR: Amber Gayle Thalmayer GRADUATE AND UNDERGRADUATE SCHOOLS ATTENDED: University of Oregon, Eugene Southern Oregon University, Ashland Goddard College, Plainfield, Vermont DEGREES AWARDED: Doctor of Philosophy, Psychology, 2013, University of Oregon Master of Science, Psychology, 2008, University of Oregon Bachelor of Science, Psychology, minor in German Language and Literature, Southern Oregon University AREAS OF SPECIAL INTEREST: Personality structure and measurement Cross-cultural issues in personality Mental health treatment PROFESSIONAL EXPERIENCE: Course instructor, Department of Psychology, University of Oregon, Eugene, 2008 - 2013 Teaching assistant and lab instructor, Department of Psychology, University of Oregon, Eugene, 2006 - 2013 Research Assistant, Department of Psychology, 2006 - 2012 Neuropsychological Testing Assistant and Interviewer, Dr. Steve Pethick, Eugene, Oregon, 2010 – 2013 Group Facilitator and diagnostic interviewer, Oregon Research Institute, Eugene, Oregon, 2011, 2013 Data Analyst, Decision Research Institute, Eugene, Oregon, 2009 GRANTS, AWARDS, AND HONORS: Graduate Teaching Fellowship, UO Department of Psychology, 2006 to present Betty Foster McCue Fellowship for Human Performance and Development, UO Graduate School 2012 vi Carolyn Stokes Memorial Scholarship, UO College of Arts and Sciences, 2012 & 2010 Gregores Award, UO Department of Psychology, 2012 Clarence and Lucille Dunbar Scholarship, UO College of Arts and Sciences, 2011 Norm Sundberg Award, UO Department of Psychology, 2011 American Association of University Women, Outstanding Graduating Woman in Psychology 2006 Summa cum laude, Southern Oregon University, 2006 PUBLICATIONS: Thalmayer, A.G.

Thank you to committee members Joseph Stevens, Sanjay Srivastava and Don Tucker for their support and assistance with my dissertation and with many other projects. My dissertation studies would not have been possible without the support of Couples and Family Therapy clinic directors Tiffany Brown and Jeff Todhal, who allowed me to collect data and work with existing data in their archives, and without ongoing assistance from clinic staff members Lalla Pudewell, Lindsay Brown, and Caitlin Peoples. This work also depended on the hard work of several undergraduate research assistants, in particular Nathan Baune, as well as Grant Rusin, Brenna Bell, Kristen Ackerman, and Thomas Bradley. Thank you to fellow doctoral students Annemarie Eigenhuis and Zhuo Job Chen for practical advice on aspects of this project, and to them and many others, in particular Ida Moadab, Allison Waters, Philippe Bou Malham, and Kathryn Iurino for camaraderie. I am grateful to many family members and close friends, especially Merilyn Wakefield, Stacy Wakefield Forte, and Elaine Deckelman, for their ongoing enthusiasm, perspective, and support. For sustaining encouragement and support virtually every day of this seven year process, I most of all thank my husband, Erich Mead Thalmayer with whom this accomplishment is shared. viii Dedicated, in memoriam, to my father, John Arthur Wakefield -- a man who revered intellectual achievements and who had more than the usual amount of personality. I think he would have been the proudest of all to have a Ph.D. in the family. ix TABLE OF CONTENTS Chapter Page I.
