Book Synopsis Longitudinal Data Analysis by : Jason Newsom
Download or read book Longitudinal Data Analysis written by Jason Newsom and published by Routledge. This book was released on 2013-06-19 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides accessible treatment to state-of-the-art approaches to analyzing longitudinal studies. Comprehensive coverage of the most popular analysis tools allows readers to pick and choose the techniques that best fit their research. The analyses are illustrated with examples from major longitudinal data sets including practical information about their content and design. Illustrations from popular software packages offer tips on how to interpret the results. Each chapter features suggested readings for additional study and a list of articles that further illustrate how to implement the analysis and report the results. Syntax examples for several software packages for each of the chapter examples are provided at www.psypress.com/longitudinal-data-analysis. Although many of the examples address health or social science questions related to aging, readers from other disciplines will find the analyses relevant to their work. In addition to demonstrating statistical analysis of longitudinal data, the book shows how to interpret and analyze the results within the context of the research design. The methods covered in this book are applicable to a range of applied problems including short- to long-term longitudinal studies using a range of sample sizes. The book provides non-technical, practical introductions to the concepts and issues relevant to longitudinal analysis. Topics include use of publicly available data sets, weighting and adjusting for complex sampling designs with longitudinal studies, missing data and attrition, measurement issues related to longitudinal research, the use of ANOVA and regression for average change over time, mediation analysis, growth curve models, basic and advanced structural equation models, and survival analysis. An ideal supplement for graduate level courses on data analysis and/or longitudinal modeling taught in psychology, gerontology, public health, human development, family studies, medicine, sociology, social work, and other behavioral, social, and health sciences, this multidisciplinary book will also appeal to researchers in these fields.

Book Synopsis Nonparametric Regression Analysis of Longitudinal Data by : Hans-Georg Müller
Download or read book Nonparametric Regression Analysis of Longitudinal Data written by Hans-Georg Müller and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph reviews some of the work that has been done for longitudi nal data in the rapidly expanding field of nonparametric regression. The aim is to give the reader an impression of the basic mathematical tools that have been applied, and also to provide intuition about the methods and applications. Applications to the analysis of longitudinal studies are emphasized to encourage the non-specialist and applied statistician to try these methods out. To facilitate this, FORTRAN programs are provided which carry out some of the procedures described in the text. The emphasis of most research work so far has been on the theoretical aspects of nonparametric regression. It is my hope that these techniques will gain a firm place in the repertoire of applied statisticians who realize the large potential for convincing applications and the need to use these techniques concurrently with parametric regression. This text evolved during a set of lectures given by the author at the Division of Statistics at the University of California, Davis in Fall 1986 and is based on the author's Habilitationsschrift submitted to the University of Marburg in Spring 1985 as well as on published and unpublished work. Completeness is not attempted, neither in the text nor in the references. The following persons have been particularly generous in sharing research or giving advice: Th. Gasser, P. Ihm, Y. P.

Book Synopsis Longitudinal Models in the Behavioral and Related Sciences by : Kees van Montfort
Download or read book Longitudinal Models in the Behavioral and Related Sciences written by Kees van Montfort and published by Routledge. This book was released on 2017-09-29 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume reviews longitudinal models and analysis procedures for use in the behavioral and social sciences. Written by distinguished experts in the field, the book presents the most current approaches and theories, and the technical problems that may be encountered along the way. Readers will find new ideas about the use of longitudinal analysis in solving problems that arise due to the specific nature of the research design and the data available. Longitudinal Models in the Behavioral and Related Sciences opens with the latest theoretical developments. In particular, the book addresses situations that arise due to the categorical nature of the data, issues related to state space modeling, and potential problems that may arise from network analysis and/or growth-curve data. The focus of part two is on the application of longitudinal modeling in a variety of disciplines. The book features applications such as heterogeneity on the patterns of a firm’s profit, on house prices, and on delinquent behavior; non-linearity in growth in assessing cognitive aging; measurement error issues in longitudinal research; and distance association for the analysis of change. Part two clearly demonstrates the caution that should be taken when applying longitudinal modeling as well as in the interpretation of the results. This new volume is ideal for advanced students and researchers in psychology, sociology, education, economics, management, medicine, and neuroscience.

Book Synopsis Amsterdam Growth and Health Longitudinal Study (AGAHLS) by : Han C. G. Kemper
Download or read book Amsterdam Growth and Health Longitudinal Study (AGAHLS) written by Han C. G. Kemper and published by Karger Medical and Scientific Publishers. This book was released on 2004 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: A unique observational long-term study In a long follow-up period of 23 years about 600 teenagers were observed till their young adult age in order to investigate the longitudinal relationship between health and lifestyles considering physical activity, diet, smoking and alcohol consumption. Longitudinal studies with a follow-up lasting for a quarter of a century are very rare and the Amsterdam Growth and Health Longitudinal Study (AGAHLS) is indeed unique among them. The focus is multidisciplinary and involves both physical and psychological determinants in relation to a wide range of health outcomes. The multiple measurements were carefully standardized in nine waves of data collection, thus producing a high-quality data set, which has been analyzed by the application of advanced statistical techniques. The monograph provides not only an overview of 23 years of follow-up, it also summarizes over 200 scientific publications and 10 PhD theses. This publication is especially recommended to investigators planning longitudinal research, to health workers, and to authorities who like to implement health promotional activities in their community.

Book Synopsis Psychological Predictors and Outcomes of Childhood Overweight and Obesity by : Emily Incledon
Download or read book Psychological Predictors and Outcomes of Childhood Overweight and Obesity written by Emily Incledon and published by . This book was released on 2011 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: Obesity has clear and serious consequences for physical health, many of which emerge in adulthood. For obese children, poor psychological health may be the most obvious and immediate implication of their excess adiposity but the evidence to support this is mixed, particularly for community-based (i.e. non-clinical) groups. Given that associations between psychological health and body mass index (BMI) are likely to be bidirectional, longitudinal methodologies seem best suited to clarify the nature of these relationships. Furthermore, research conducted with community-based samples may be generalizable to the wider population of overweight and obese children. However, most research to date has been cross-sectional and conducted with clinical populations of obese children. In light of these evidence gaps, the first objective of this thesis was to determine the longitudinal relationship between psychological well-being and subsequent excess adiposity gain and obesity onset across childhood and adolescence. This was addressed in a systematic review (Paper 1) and a research paper (Paper 2). The systematic review, which selected population-based studies for maximum generalizability, suggested that poorer psychological well-being may increase the incidence of obesity and contribute to obesity persistence across adolescence. However, major limitations and inconsistencies were identified in the literature. Paper 2 of this thesis addressed a gap identified in the systematic literature review- the need for further good-quality research examining individual psychological predictors of adiposity change in the overweight or obese subgroup. It employed a longitudinal cohort of 5-9 year old children who were all initially overweight or mildly obese when they presented to primary care 4 years earlier. Parallel parent proxy- and child self- reported psychosocial measures were assessed as predictors of changes in body mass index (BMI; kg/m2) standard deviation scores (i.e. BMI z-scores). Results revealed little evidence that initial psychosocial functioning impacted on subsequent BMI z-score change. However, changes in several domains of psychosocial well-being, especially in relation to body-image and appearance, were associated with concomitant BMI z-score change. A strong degree of corroboration between parents and children strengthened the validity of the findings.The second objective of the thesis was to investigate whether and how BMI was associated with psychological outcomes among non-clinical overweight or obese children. Consistent with Paper 2, Paper 3 achieved this within a cohort of 5-9 year olds recruited from primary care for their overweight or mild obesity. Results confirmed that overall, psychological well-being at 4-year follow-up was weakly predicted by concurrent BMI and when impairments were found, they were most likely for peer and eating-behaviour domains. This study extended on existing knowledge by demonstrating that changes in BMI categories also contributed little variance to the psychological outcomes of initially overweight children. The implications of this research focus on informing effective prevention strategies to reverse the current trends in youth obesity. Recommendations include targeting poor psychological well-being prior to adolescence to yield the most benefit for preventing the onset of obesity. Intervention strategies for the quarter of children in the community who are overweight or obese could incorporate modules that target peer relationship and eating problems, the most relevant psychological comorbidities of excess adiposity. Enhancing well-being in these domains would be beneficial for immediate quality of life, future mental health and potentially initiate flow-on effects that improve physical health.
Book Synopsis Nonparametric Analysis of Longitudinal Data in Factorial Experiments by : Edgar Brunner
Download or read book Nonparametric Analysis of Longitudinal Data in Factorial Experiments written by Edgar Brunner and published by Wiley-Interscience. This book was released on 2002 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authoritative reference on nonparametric methods for evaluating longitudinal data in factorial designs Broadening the range of techniques that can be used to evaluate longitudinal data, Nonparametric Analysis of Longitudinal Data in Factorial Experiments presents nonparametric methods of evaluation that supplement the generalized linear models approach. Emphasizing the practical application of these methods in statistical procedures, this book provides a unified approach for the analysis of factorial designs involving longitudinal data that is appropriate for metric data, count data, ordered categorical data, and dichotomous data. Topics covered include nonparametric models, effects and hypotheses in experimental design, estimators for relative effects, experiments for one and several groups of subjects, multifactorial experiments, dependent replications, and experiments with numerous time points. The basic mathematical principles for the methods introduced here are described in theory, consistent with the book's minimal math requirements. Simple approximations for small data sets are provided, as well as ample chapter exercises to test skills, an appendix that includes original data for the examples used throughout the book, and downloadable SAS-IML macros for implementing the more extensive calculations. All applications are designed to be useful in many fields. Generously supplemented with more than 110 graphs and tables, Nonparametric Analysis of Longitudinal Data in Factorial Experiments is an essential reference for statisticians and biometricians, researchers in clinical trials, psychological studies, and in the fields of forestry, agriculture, sociology, ecology, and biology, as well as graduate students in statistics and biostatistics.
Book Synopsis Are Time Preference and Body Mass Index Associated? by : Patricia K. Smith
Download or read book Are Time Preference and Body Mass Index Associated? written by Patricia K. Smith and published by . This book was released on 2006 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The prevalence of obesity among both adults and children in the U.S. has risen to all time highs in the past two decades. We propose that an increase in the marginal rate of time preference has contributed to increasing obesity. More people are consuming more calories than they expend because they have become less willing to trade current pleasure for potential future health benefits. Accordingly, this paper explores the association between body mass index (BMI) and time preference. We use the National Longitudinal Survey of Youth (NLSY79) to test our hypothesis that time preference and BMI are positively related. We find some evidence that there is such a positive association among black and Hispanic men and black women.
