Originally published in 1976, the authors of six of the most widely quoted works in behavioural science related to education, at the time, here describe in detail their research work, including its origins, planning and implementation. The accounts are unusual, not only for their technical detail but for their candour. The brief was to put the heart and brains back into accounts of research so the authors comment not only on the research design, but on the personal and professional problems they had to overcome. They also reflect on the reception of their work, and the way in which it has been adapted, misunderstood or deliberately distorted to support arguments of widely differing ideological pressure groups. The book shows how ingenuity and persistence as well as technical competence lie at the heart of the research process. The authors do not give the normal depersonalised, streamlined account which gives a false, mechanical picture of research as an occupation, but show it to be a profound personal and professional experience as they comment on the thought that lay behind their work and the way it was finally produced for publication. Dr Shipman has written a short introduction to each chapter, and contributed a concluding chapter relating the six research experiences to conventional views on the research process and to the part played by research evidence in policy making.

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.

Longitudinal Analysis provides an accessible, application-oriented treatment of introductory and advanced linear models for within-person fluctuation and change. Organized by research design and data type, the text uses in-depth examples to provide a complete description of the model-building process. The core longitudinal models and their extensions are presented within a multilevel modeling framework, paying careful attention to the modeling concerns that are unique to longitudinal data. Written in a conversational style, the text provides verbal and visual interpretation of model equations to aid in their translation to empirical research results. Overviews and summaries, boldfaced key terms, and review questions will help readers synthesize the key concepts in each chapter. Written for non-mathematically-oriented readers, this text features: A description of the data manipulation steps required prior to model estimation so readers can more easily apply the steps to their own data An emphasis on how the terminology, interpretation, and estimation of familiar general linear models relates to those of more complex models for longitudinal data Integrated model comparisons, effect sizes, and statistical inference in each example to strengthen readers'understanding of the overall model-building process Sample results sections for each example to provide useful templates for published reports Examples using both real and simulated data in the text, along with syntax and output for SPSS, SAS, STATA, and Mplus at www.PilesOfVariance.com to help readers apply the models to their own data The book opens with the building blocks of longitudinal analysis—general ideas, the general linear model for between-person analysis, and between- and within-person models for the variance and the options within repeated measures analysis of variance. Section 2 introduces unconditional longitudinal models including alternative covariance structure models to describe within-person fluctuation over time and random effects models for within-person change. Conditional longitudinal models are presented in section 3, including both time-invariant and time-varying predictors. Section 4 reviews advanced applications, including alternative metrics of time in accelerated longitudinal designs, three-level models for multiple dimensions of within-person time, the analysis of individuals in groups over time, and repeated measures designs not involving time. The book concludes with additional considerations and future directions, including an overview of sample size planning and other model extensions for non-normal outcomes and intensive longitudinal data.Class-tested at the University of Nebraska-Lincoln and in intensive summer workshops, this is an ideal text for graduate-level courses on longitudinal analysis or general multilevel modeling taught in psychology, human development and family studies, education, business, and other behavioral, social, and health sciences. The book's accessible approach will also help those trying to learn on their own. Only familiarity with general linear models (regression, analysis of variance) is needed for this text.

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.

This book updates the progress into adulthood of the cohort of fourteen-year-olds who were recruited and tracked until they were eighteen years old. Illegal Leisure (1998) described their adolescent journeys and lifestyles, focusing on their early regular drinking and extensive ‘recreational'drug use.This new edition revisits these original chapters, providing commentaries around them to discuss current implications of the original publication, plus documenting and discussing the group at twenty-two and twenty-seven years of age. Illegal Leisure Revisited positions the journeys of these twenty-somethings against the ever-changing backdrop of a consumption-oriented leisure society, the rapid expansion of the British night-time economy and the place of substance use in contemporary social worlds. It presents to the reader the ways in which these young people have moved into the world of work, long-term relationships and parenthood, and the resulting changes in the function and frequency of their drinking and drug-use patterns. Amid dire public health warnings about their favourite intoxicants, and with the growing criminalisation of a widening array of recreational drugs, the book revisits these young people as they continue as archetypal citizens in a risk society.The book is ideal reading for researchers and undergraduate students from a variety of fields, such as developmental and social psychology, sociology, criminology, cultural and health studies. Professionals working in criminal justice, health promotion, drugs education, harm reduction and treatment will also find this book an invaluable resource.

Data generated from longitudinal studies allow researchers to better understand how context and experience interact with stable characteristics of the developing person over time. This book summarizes a landmark longitudinal study of 200 children, from the ages of 3 to 23. The Munich Longitudinal Study on the Ontogenesis of Individual Competencies (LOGIC) examined the development of individual differences over time and whether it is possible to predict later competencies from earlier ones. Offering a snapshot of theory and data on personality, social, motor, moral, and cognitive development, the contributors help us understand which individual differences can and cannot be altered through schooling and other experiences and how differences seen in the earliest stages are later reflected in adulthood. The results provide valuable insight into the strengths and limitations of early prediction of individual differences. This is the second volume to review the wealth of data generated by the study. The first volume (Weinert and Schneider, 1999) traced development from ages 3 to 12. This volume continues the story, integrating these early findings with the results from adolescence and young adulthood. Each of the chapters provides an overview of current research and addresses how the data help us understand the presence and developmental effects of individual differences. Among the findings are results on: The relative stability of cognitive competencies The long term effects of shyness and aggression The relation between moral understanding and action, and The role of education in the development or maintenance of performance differences. Intended for researchers and advanced students in developmental, educational, personality, social, and cognitive psychology, this book will also appeal to educators, especially the chapters that focus on literacy development, educational context, scientific reasoning and mathematical reasoning.

This innovative volume demonstrates the use of a range of statistical approaches that examine'turning points'(a change in direction, magnitude, or meaning) in real data. Analytic techniques are illustrated with real longitudinal data from a variety of fields. As such the book will appeal to a variety of researchers including: Developmental researchers interested in identifying factors precipitating turning points at various life stages. Medical or substance abuse researchers looking for turning points in disease or recovery. Social researchers interested in estimating the effects of life experiences on subsequent behavioral changes. Interpersonal behavior researchers looking to identify turning points in relationships. Brain researchers needing to discriminate the onset of an experimentally produced process in a participant. The book opens with the goals and theoretical considerations in defining turning points. An overview of the methods presented in subsequent chapters is then provided. Chapter goals include discriminating'local'from long-term effects, identifying variables altering the connection between trajectories at different life stages, locating non-normative turning points, coping with practical distributional problems in trajectory analyses, and changes in the meaning and connections between variables in the transition to adulthood. From an applied perspective, the book explores such topics as antisocial/aggressive trajectories at different life stages, the impact of imprisonment on criminal behavior, family contact trajectories in the transition to adulthood, sustained effects of substance abuse, alternative models of bereavement, and identifying brain changes associated with the onset of a new brain process. Ideal for advanced students and researchers interested in identifying significant change in data in a variety of fields including psychology, medicine, education, political science, criminology, and sociology.

This edited volume introduces the latest advances in quantitative methods and illustrates ways to apply these methods to important questions in substance use research. The goal is to provide a forum for dialogue between methodologists developing innovative multivariate statistical methods and substance use researchers who have produced rich data sets.Reflecting current research trends, the book examines the use of longitudinal techniques to measure processes of change over time. Researchers faced with the task of studying the causes, course, treatment, and prevention of substance use and abuse will find this volume helpful for applying these techniques to make optimal use of their data.This innovative volume: introduces the use of latent curve methods for describing individual trajectories of adolescent substance use over time; explores methods for analyzing longitudinal data for individuals nested within groups, such as families, classrooms, and treatment groups; demonstrates how different patterns of missing data influence the interpretation of results; reports on some recent advances in longitudinal growth modeling; illustrates methods to assess mediation when there are multiple mediating pathways underlying an intervention effect; describes methods to identify moderating relations in structural equation models; demonstrates the use of structural equation models to evaluate a preventive intervention; applies epidemic modeling techniques to understand the spread of substance use in society; illustrates the use of latent transition analysis to model substance use as a series of stages; and applies logistic regression to prospectively predict smoking cessation.

Home Environment and Early Cognitive Development: Longitudinal Research presents the results of longitudinal studies in Canada and the United States that looked into the relationship between home environment and early cognitive development. The aim of these investigations is to determine the specific or process home environmental variables that correlate with and possibly regulate cognitive development during infancy and the preschool years. Comprised of 10 chapters, this book begins with a brief introduction to the issues investigated. Each of the following seven chapters is devoted to a longitudinal investigation, with emphasis on data presentation, analysis, and interpretation. The influence of home environment on cognitive development in young children of middle-socioeconomic-status families as well as Mexican-American children is considered. Assessments of cognitive development are carried out using standard psychometric tests of intelligence; Piagetian-type measures of sensorimotor development; measures of language development; and measures of recognition memory for infants. The final chapter assesses the implications for intervention of the link between home environment and early cognitive development. This monograph will be of interest to psychologists and sociologists.

This international study of children's experiences of organized persecution, explores the Holocaust and its aftermath as prototypical social trauma. Traumatized persons'feelings of shame and guilt as well as a sense of being different may prevail, and they may attribute great power to others, seek safety in isolation, or search for a rescuer. Nevertheless, as a group, the child survivors of the Holocaust have achieved remarkable success as adults.Drawing on the wealth of personal and interview information, the contributors create a synthesis of personal history and psychological analysis. Adult memories of traumatic childhood experiences are accompanied by discussions of their effects and by analysis of the various coping mechanisms used to establish a viable post-war existence. These accounts are distinguished by the fact that they are by and about individuals who grew up in undistinguished Christian and Jewish families; not those of prominent figures or resistance fighters or rescuers. All experienced unrest and many suffered trauma during the Nazi regime, as a result of the war, and during the post-war turbulence. An important collection for students and scholars of the Holocaust and for those professionals in a position to help surviving victims of other organized persecution, civil violence, strife, and abuse.

Epidemiological surveys have provided key information about the prevalence and degree of seriousness at different ages of a wide array of problem behaviors such as delinquency, substance use, early sexual involvement, and mental health disorders. Knowledge of the extent of these problems and changes in their course over time is important. In its absence, interventions and health planning in general can be difficult. Understanding which risk and protective factors are relevant to which problem behaviors is also essential for the formulation of theories that constitute the basis of intervention. This book draws on the results of the major Pittsburgh Youth Study complemented by follow-up tracking of juvenile court records for more than six years, to address the following questions: •What is the prevalence and age of onset of delinquency, substance use, and early sexual behavior for three samples of boys age 8, 11, and 14? What are the average mental health problems for these ages? How strong are the relationships among these problem behaviors in each of the samples? •Which variables best explain individual differences among the boys in their manifestations of delinquency, substance use, early sexual behavior, and mental health problems? To what extent do explanatory factors vary with age? How accurately can boys with different outcomes be identified by risk scores based on hierarchical multiple regressions? •To what extent are explanatory factors associated with one outcome that are also associated with other outcomes? Are explanatory factors that are especially characteristic of a multiproblem group of boys--who display many different problem behaviors--different from explanatory factors associated with boys with few problems? •Do the results fit a general theory of juvenile problem behaviors, or is a differentiated theory more applicable?

Growing Up to be Violent: A Longitudinal Study of the Development of Aggression deals with the study of psychosocial development concerning aggressive behavior in third-grade schoolchildren and their upbringing. The design of the study is longitudinal—a follow-up research has been made when the children reached the twelfth grade. The book explains that certain child-rearing practices and some environmental factors can be predictors of aggressive behavior during young adulthood. The text also reviews the various theories of aggression including the theory of innate aggressiveness and the social learning of aggression. The book discusses the roots of aggression, the four classes of environmental variables (instigators, punishment, identification, sociocultural variables), as well as, sex differences and perinatal complications in aggression. The book addresses the effects of television in the development of aggressive behavior: that television can incite aggression and present certain ways of practicing aggressiveness. The book points that young adults who were intelligent, popular and polite as young children have positive social position as young adults. This book can prove insightful for psychiatrists, psychologists, behavioral scientists, child educators, students or professors in psychology, and for parents of young children.

Single Subject Research: Strategies for Evaluating Change presents an overview of strategies used to evaluate change in single subject research, a particular approach referring to time-series paradigms in which each subject is used repeatedly. These strategies include research design, graphical analysis, and statistical tests, and it will be apparent that such designs extend beyond those commonly employed in applied behavioral research. The book opens with a brief historical perspective of time-series and other small group research. Separate chapters follow covering the analysis of graphic data as being of singular importance in single subject research; the units-of-analysis issue and a nonparametric randomization approach to data analysis; and the growing awareness among researchers that understanding the individual characteristics of interacting subjects may be inadequate for understanding the process that has taken place between them. The final chapter reviews the advantages and disadvantages of the analytic methods presented in the previous chapters. This volume will be of interest to those individuals actively engaged in educational and psychological experimentation for which single subject research strategies are or may prove to be valuable. Students desiring to supplement their knowledge of a unique and rapidly emerging area of statistical analysis as applied to single subject research designs will also find this volume of importance.

Written by a pediatrician/adolescent medicine specialist and a developmental psychologist, this book is a collection of informative, nonredundant yet comprehensive studies on adolescent pregnancy and parenting. More than 200 adolescent women in an ethnically diverse sample were studied prenatally and at regular 6-month intervals for 3½ years postpartum. Most of the teens were poor, unmarried, first-time mothers who resided within Southeast San Diego, a poor urban area approximately 10 miles north of the U.S.-Mexico border. The purpose of this book was to offer researchers, practitioners, program directors, teachers, and graduate and medical students a better understanding of teenage pregnancy and parenthood within the following domains: • adolescent prenatal care and postpartum maternal and infant health outcomes, • immediate repeat pregnancy, • adolescent mothers'parenting, • the role of the adolescent's mother in teenage mothers'parenting, and • the baby's father.

This book presents a longitudinal study dealing with developmental changes within and between self-concepts and their relation to personal functioning. Within the psychological literature -- and the developmental literature in particular -- the interest in the ideas people hold about themselves and their relation with personal functioning is rapidly growing. This interest is reinforced by the emphasis on individuality in Western society. The self-system is now thought to consist of a collection of self-concepts in which a distinction is made between domain-specific self-concepts -- the real and ideal -- and context-related self-concepts -- the academic, the athletic and the social. It is also considered to be subjective rather than objective. This subjective self involves characteristics such as continuity and distinctiveness from others. These characteristics have been the primary focus of recent research. In existing literature on the development of the self-system, little is known about the structural characteristics -- that is, developmental changes in the interrelationships among domain-specific and context-related self-concepts, or between and within self-concepts. Similarly, little information is available about the relationships between individuals'real and ideal self concepts, their perceived concepts of others, and the actual ideas others have about the same individuals. This book integrates hitherto separate and different components or aspects of self-knowledge into one encompassing, multidimensional self-system.
