Download or read book The Handbook of Personality Dynamics and Processes written by John F. Rauthmann and published by Academic Press. This book was released on 2021-01-20 with total page 1406 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Handbook of Personality Dynamics and Processes is a primer to the basic and most important concepts, theories, methods, empirical findings, and applications of personality dynamics and processes. This book details how personality psychology has evolved from descriptive research to a more explanatory and dynamic science of personality, thus bridging structure- and process-based approaches, and it also reflects personality psychology's interest in the dynamic organization and interplay of thoughts, feelings, desires, and actions within persons who are always embedded into social, cultural and historic contexts. The Handbook of Personality Dynamics and Processes tackles each topic with a range of methods geared towards assessing and analyzing their dynamic nature, such as ecological momentary sampling of personality manifestations in real-life; dynamic modeling of time-series or longitudinal personality data; network modeling and simulation; and systems-theoretical models of dynamic processes. - Ties topics and methods together for a more dynamic understanding of personality - Summarizes existing knowledge and insights of personality dynamics and processes - Covers a broad compilation of cutting-edge insights - Addresses the biophysiological and social mechanisms underlying the expression and effects of personality - Examines within-person consistency and variability

Download or read book Latent Class and Latent Transition Analysis written by Linda M. Collins and published by John Wiley & Sons. This book was released on 2013-05-20 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: A modern, comprehensive treatment of latent class and latent transition analysis for categorical data On a daily basis, researchers in the social, behavioral, and health sciences collect information and fit statistical models to the gathered empirical data with the goal of making significant advances in these fields. In many cases, it can be useful to identify latent, or unobserved, subgroups in a population, where individuals' subgroup membership is inferred from their responses on a set of observed variables. Latent Class and Latent Transition Analysis provides a comprehensive and unified introduction to this topic through one-of-a-kind, step-by-step presentations and coverage of theoretical, technical, and practical issues in categorical latent variable modeling for both cross-sectional and longitudinal data. The book begins with an introduction to latent class and latent transition analysis for categorical data. Subsequent chapters delve into more in-depth material, featuring: A complete treatment of longitudinal latent class models Focused coverage of the conceptual underpinnings of interpretation and evaluationof a latent class solution Use of parameter restrictions and detection of identification problems Advanced topics such as multi-group analysis and the modeling and interpretation of interactions between covariates The authors present the topic in a style that is accessible yet rigorous. Each method is presented with both a theoretical background and the practical information that is useful for any data analyst. Empirical examples showcase the real-world applications of the discussed concepts and models, and each chapter concludes with a "Points to Remember" section that contains a brief summary of key ideas. All of the analyses in the book are performed using Proc LCA and Proc LTA, the authors' own software packages that can be run within the SAS® environment. A related Web site houses information on these freely available programs and the book's data sets, encouraging readers to reproduce the analyses and also try their own variations. Latent Class and Latent Transition Analysis is an excellent book for courses on categorical data analysis and latent variable models at the upper-undergraduate and graduate levels. It is also a valuable resource for researchers and practitioners in the social, behavioral, and health sciences who conduct latent class and latent transition analysis in their everyday work.

Download or read book Psychosocial Risk Factors in the Development Maintenance and Treatment Outcome of Eating Disorders written by Matteo Aloi and published by Frontiers Media SA. This book was released on 2024-09-25 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eating disorders (EDs) are mental disorders characterized by altered eating habits and excessive concerns about weight and body shape. They arise mainly during adolescence and predominantly affect females. The three most common types of EDs are: •Anorexia nervosa (AN), which is characterized by restriction of food intake, significant low body weight, an intense fear of gaining weight and disturbances in body shape and weight experience; •Bulimia nervosa (BN), which is characterized by recurrent binge-eating episodes followed by behaviors that compensate for the overeating (i.e., self-induced vomiting, excessive exercise, or extreme use of laxatives, enemas or diuretics), and self-evaluation based on body shape and weight; •Binge eating disorder (BED), which is characterized by the recurrence of binge-eating episodes without the use of compensatory behaviors for weight control, and feelings of distress, embarrassment and guilt. To date, researchers and clinicians agree that a multifactorial model is the most suitable for explaining the onset and maintenance of EDs. For example, a risk factor for BED may be lower parental care, as it may trigger greater confusion and uncertainty in responding to unpleasant emotional experiences. This contributes to an impaired personality development, more severe psychopathological symptomatology, and greater difficulty in both identifying and distinguishing feelings of hunger and satiety from other emotions. Attachment styles have also been explored in patients with EDs. According to the attachment theory, attachment insecurity could disrupt the ability to identify and express emotional states and might impair affect regulation skills (i.e. emotional dysregulation). Within the two main dimensions of attachment insecurity (i.e., attachment anxiety and avoidance), higher attachment anxiety is related to greater symptom severity in patients with AN and BN. Moreover, prior studies have examined impaired emotional competences (ECs), theory of mind (ToM) and metacognition, which refer to how individuals identify, express, understand, regulate, and use their emotions or those of significant others. These skills may also explain why attachment insecurity places individuals at greater risk of EDs. Although particular personality traits (i.e. impulsivity, perfectionism, self-esteem), attachment styles, trauma, and metacognition clearly play a role in the onset and maintenance of EDs, little is known about their associations and underlying mechanisms.

Download or read book The SAGE Handbook of Quantitative Methodology for the Social Sciences written by David Kaplan and published by SAGE. This book was released on 2004-06-21 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantitative methodology is a highly specialized field, and as with any highly specialized field, working through idiosyncratic language can be very difficult made even more so when concepts are conveyed in the language of mathematics and statistics. The Sage Handbook of Quantitative Methodology for the Social Sciences was conceived as a way of introducing applied statisticians, empirical researchers, and graduate students to the broad array of state-of-the-art quantitative methodologies in the social sciences. The contributing authors of the Handbook were asked to write about their areas of expertise in a way that would convey to the reader the utility of their respective methodologies. Relevance to real-world problems in the social sciences is an essential ingredient of each chapter. The Handbook consists of six sections comprising twenty-five chapters, from topics in scaling and measurement, to advances in statistical modelling methodologies, and finally to broad philosophical themes that transcend many of the quantitative methodologies covered in this handbook.

Download or read book Latent Variable Models and Factor Analysis written by David J. Bartholomew and published by Wiley. This book was released on 1999-08-10 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hitherto latent variable modelling has hovered on the fringes of the statistical mainstream but if the purpose of statistics is to deal with real problems, there is every reason for it to move closer to centre stage. In the social sciences especially, latent variables are common and if they are to be handled in a truly scientific manner, statistical theory must be developed to include them. This book aims to show how that should be done. This second edition is a complete re-working of the book of the same name which appeared in the Griffin’s Statistical Monographs in 1987. Since then there has been a surge of interest in latent variable methods which has necessitated a radical revision of the material but the prime object of the book remains the same. It provides a unified and coherent treatment of the field from a statistical perspective. This is achieved by setting up a sufficiently general framework to enable the derivation of the commonly used models. The subsequent analysis is then done wholly within the realm of probability calculus and the theory of statistical inference. Numerical examples are provided as well as the software to carry them out ( where this is not otherwise available). Additional data sets are provided in some cases so that the reader can aquire a wider experience of analysis and interpretation.
