Exercise & Physical Activity in Middle Exercise & Physical Activity in Middle-Aged Women: The Role of Self-Compassion DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Michelle Susan Thall, M.S. Graduate Program in Education The Ohio State University 2014 Dissertation Committee: Professor Janet Buckworth, Advisor Professor Diane Habash Professor Maryanna Klatt i i Abstract Americans do not engage in sufficient physical activity and exercise (PA/Ex). PA/Ex declines with age and women are less active than men. Research suggests a focus on immediate benefits of PA/Ex may increase PA/Ex motivation. Self-compassion, a psychological construct comprised of self-kindness, mindfulness and common humanity, is correlated with several indicators of acute positive affect. In the last four years, 10 published studies have explored the relationship between self-compassion, body image and exercise in youth or young-adult populations. This study’s purpose was to contribute to such research by investigating self-compassion’s influence on body image, exercise motivation and PA/Ex in middle-aged women. Women were eligible for this study if they were 35-60 years of age, not pregnant (or within one year postpartum), and able to be physically active. Participants were recruited from the ResearchMatch database and completed a survey developed using Qualtrics Research Suite. In September 2013, 1,303 participants accessed the on-line survey. After allowing for individuals who did not consent to take the survey, data errors, and treatment for missing values and outliers, 1,213 complete cases were available for data analysis. Of these, 1,122 non-African American participants were initially analyzed as the literature indicated African American women may differ significantly from other ethnic groups in perceptions of body image. ii Average age and BMI of the1,122 women participants were 48, and 28 kg/m2, respectively. Seventy-one percent of the participants met or exceeded the 150-minute recommended level of moderate aerobic activity per week, as compared to 50% of women aged 35-64 in the 2011 Behavioral Risk Factor Surveillance System. A confirmatory factor analysis conducted within structural equation modeling (SEM) using LISREL indicated appearance evaluation, health/fitness evaluation, health/fitness orientation, and body appreciation were significant dimensions of body image (p < .001, in all cases), while amotivation, extrinsic motivation, identified motivation, and intrinsic motivation were significant aspects of exercise motivation (p < .001, in all cases) Appearance orientation and introjected motivation were not significant dimensions of body image (p = .136) and exercise motivation (p = .646), respectively. The final structural equation model indicated that in this population of middle- aged women, self-compassion positively predicts body image, which in turn predicts autonomous exercise motivation and consequently, higher levels of PA/Ex participation (SRMR = .05, and GFI = .952). Further, contrary to hypotheses based upon the literature, Body Mass Index (BMI) and age were not significant predictors of PA/Ex participation in this sample of women, though BMI and age were both significantly and positively correlated with self-compassion levels. In depth analysis of the relationship between self-compassion and body image suggests self-compassion might be viable as a coping mechanism to relieve negative repercussions of poor body image, encourage body appreciation and ultimately lead to increases in PA/Ex levels in the population of middle-aged women. Future research iii should focus on examining commonalities between self-compassion and distinct aspects of body image and how increases in levels of self-compassion and body appreciation can increase the likelihood that middle-aged women will autonomously adopt and maintain more active lifestyles. iv Acknowledgements I acknowledge the help of all mentors, colleagues, co-workers, friends and family who have made this research and this document possible. To those few who I am certain I will forget to mention by name, I am eternally grateful regardless. First to my amazing dissertation committee, Dr. Janet Buckworth, Dr. Diane Habash and Dr. Maryanna Klatt, thank you for your brilliance, knowledge, common sense and unlimited supply of patience. A special thanks to Dr. Richard Lomax and Dr. Joseph Gliem for their statistical wizardry, analytical guidance and general geek support. I also want to acknowledge the incomparable guidance of Rose Hallern and CCTS in recruiting my sample. Without her assistance I could not have even begun my study. And finally to two special friends who have taught me to put my head down, barrel through and “git-er-done,” John Borowski and Dr. Chris Hearon. Thanks for always getting my back! I cannot imagine weathering graduate studies without the camaraderie of colleagues and co-workers who made the Fish Bowl come to life. You know who you are, no names will be dropped. You made life fun, interesting, bizarre, and sometimes, just bearable. To a special group of women who supported me through laughter and tears, I express the utmost in gratitude, and I support you right back. To Liz Balk, who v could always put a smile on my face, regardless of the situation, and to Chris Wilks for reminding me to silence the committee in my head, thank you, thank you, thank you. Coming to the OSU and successfully navigating a new city, a new home, a new job, a new academic program and a traumatic car accident wasn’t easy. But it wasn’t impossible because of two great people, my mom, and my friend Vikkie. My mom supported me financially, medically, logistically and emotionally; she is the best mom I know and put up with me even when I was beyond impossible. Vikkie rose to all occasions, from taking care of my dog after my accident, to welcoming me into her home, her family and her life. I was never alone because she shared so much with me. And finally a big thanks to the following: My next-door neighbor Jed for …too many things to say and count. My daddy for looking in on me from time to time. My dog Eppy for being exactly as she is. My friend Ayla for cluing me in to the “blue hairs,” and keeping me safe. The universal subconscious mind for the Law of Attraction. I’d also like to acknowledge the groundbreaking work of several scholars without whom I would never have gotten here: Kristin Neff, Naomi Wolf, Edward Deci and Richard Ryan, again, my amazing advisor, Janet Buckworth, Chris Germer, John Kabat Zinn and Jay Kimiecik. It’s been an honor to immerse myself in your knowledge and develop my research study on the backbone of your findings. With gratitude, peace and humility, M- vi Vita 1985 ………………. B.S.

  • Gröbner Basis and Structural Equation Modeling by Min Lim a Thesis
    Grobner¨ Basis and Structural Equation Modeling by Min Lim A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Graduate Department of Statistics University of Toronto Copyright c 2010 by Min Lim Abstract Gr¨obnerBasis and Structural Equation Modeling Min Lim Doctor of Philosophy Graduate Department of Statistics University of Toronto 2010 Structural equation models are systems of simultaneous linear equations that are gener- alizations of linear regression, and have many applications in the social, behavioural and biological sciences. A serious barrier to applications is that it is easy to specify models for which the parameter vector is not identifiable from the distribution of the observable data, and it is often difficult to tell whether a model is identified or not. In this thesis, we study the most straightforward method to check for identification – solving a system of simultaneous equations. However, the calculations can easily get very complex. Gr¨obner basis is introduced to simplify the process. The main idea of checking identification is to solve a set of finitely many simultaneous equations, called identifying equations, which can be transformed into polynomials. If a unique solution is found, the model is identified. Gr¨obner basis reduces the polynomials into simpler forms making them easier to solve. Also, it allows us to investigate the model-induced constraints on the covariances, even when the model is not identified. With the explicit solution to the identifying equations, including the constraints on the covariances, we can (1) locate points in the parameter space where the model is not iden- tified, (2) find the maximum likelihood estimators, (3) study the effects of mis-specified models, (4) obtain a set of method of moments estimators, and (5) build customized parametric and distribution free tests, including inference for non-identified models.

  • A Guide to Statistical Software
    A Guide to Statistical Software Commercially Available Software There are three general classes of software available using several different user interfaces. Statistical software begins to blend in one direction with relational database software such as Oracle or Sybase (software we do not discuss here) and with mathematical software such as MATLAB in the other direction. Mathematical software exhibits not only statistical capabilities flowing from code for matrix manipulation, but also optimization and symbolic manipulation useful for statistical purposes. Finally visualization software overlaps to some extent with software intended for exploratory data analysis. The user interfaces common range from command line to graphical user interfaces (GUI) to hybrid drag and drop system interfaces. We cast our net fairly widely in describing commercial software because of the general boundary crossing capabilities of the software systems. The SAS® System for Statistical Analysis SAS began as a statistical analysis system in the late 1960's growing out of a project in the Department of Experimental Statistics at North Carolina State University. The SAS Institute was founded in 1976. Since that time, the SAS System has expanded to become an evolving system for complete data management and analysis. Among the products making up the SAS System are products for: management of large data bases; statistical analysis of time series; statistical analysis of most classical statistical problems, including multivariate analysis, linear models (as well as generalized linear models), and clustering; data visualization and plotting. A geographic information system is one of the products available in the system. The SAS System is available on PC and UNIX based platforms, as well as on mainframe computers.

Abstract The CALIS procedure in SAS/STAT is a general structural equation modeling (SEM) tool. This workshop introduces the general methodology of SEM and the applications of the CALIS procedure. Historical topics such as casual models, path diagram, confirmatory factor‐analysis, measurement error model, and linear structural relations (LISREL) are reviewed. Applications of the CALIS procedure to SEM are demonstrated with examples in social, educational, behavioral, and marketing research. Specifically, the following how‐to techniques of the CALIS procedure (SAS/STAT 9.22) are covered: (1) Specifying structural equation models with latent variables by using the PATH modeling language; (2) Interpreting the model fit statistics and estimation results; (3) Testing models with multiple groups and multiple models; (4) Analyzing direct and indirect effects; (5) Modifying structural equation models. This workshop is designed for statisticians and data analysts who want to overview the applications of the SEM by the CALIS procedure. Attendees should have a basic understanding of regression analysis and experience using the SAS language.

    POWER ANALYSIS FOR PARAMETER ESTIMATION IN SEM 1 Power Analysis for Parameter Estimation in Structural Equation Modeling: A Discussion and Tutorial Y. Andre Wang Mijke Rhemtulla University of California, Davis In press at Advances in Methods and Practices in Psychological Science Correspondence should be addressed to Y. Andre Wang, Department of Psychology, University of California, One Shields Avenue, Davis, CA 95616, email: [email protected]. POWER ANALYSIS FOR PARAMETER ESTIMATION IN SEM 2 Abstract Despite the widespread and rising popularity of structural equation modeling (SEM) in psychology, there is still much confusion surrounding how to choose an appropriate sample size for SEM. Currently available guidance primarily consists of sample size rules of thumb that are not backed up by research, and power analyses for detecting model misfit. Missing from most current practices is power analysis to detect a target effect (e.g., a regression coefficient between latent variables). In this paper we (a) distinguish power to detect model misspecification from power to detect a target effect, (b) report the results of a simulation study on power to detect a target regression coefficient in a 3-predictor latent regression model, and (c) introduce a Shiny app, pwrSEM, for user-friendly power analysis for detecting target effects in structural equation models. Keywords: power analysis, structural equation modeling, simulation, latent variables POWER ANALYSIS FOR PARAMETER ESTIMATION IN SEM 3 Power Analysis for Parameter Estimation in Structural Equation Modeling: A Discussion and Tutorial Structural equation modeling (SEM) is increasingly popular as a tool to model multivariate relations and to test psychological theories (e.g., Bagozzi, 1980; Hershberger, 2003; MacCallum & Austin, 2000).

  • Comparing Vanderbilt's Software Availability and Pricing to Other
    Comparing Vanderbilt’s Software Availability and Pricing to Other Comparable Universities Jessica Cornelius1 Vanderbilt University Kennedy Center for Research on Human Development Introduction Part of Vanderbilt’s support for the Kennedy Center Investigators is the campus wide site license program for scientific computer software, ranging from popular programs like SPSS or Endnotes to niche products like BILOG_MG or Parascale, with small numbers of users. This research was conducted to compare Vanderbilt University’s distribution of mathematical and statistical software to similarly ranked institutions across the United States. Rankings were taken from the 2005 edition of the annual US News and World Reports, ‘National Top Universities’ listing (University Rankings). In addition to Vanderbilt, 10 private universities were chosen for comparison; in addition the University of Tennessee and the University of California at Davis were added because they have reputations for offering outstanding site license programs. Once the list of 13 universities was chosen, data was collected from these universities to evaluate the availability of programs to faculty or staff and the price they would pay for a license purchased through the school’s Information Technology Services (ITS) Department, or similar department. This data was used to see if Vanderbilt Kennedy Center Investigators were getting enough support from the ITS, and how it compared to other peer Universities. Methods Used Information was gathered about the availability of a mathematical or statistical program through a university’s software department and the pricing of 1 Revised with suggestions from Warren Lambert, Ph.D., of Vanderbilt University Kennedy Center for Research on Human Development. 1 these programs.
