Originally published in 1969, this book deals extensively with the description and measurement of personality.

Beginning with a statement of the principles of typological research in psychology, set against the background of general taxonomic principles in biology, the study discusses in detail results and generalisations from the Eysencks previous work. The second part of the book describes several large-scale studies using personality questionnaires prepared by the authors, as well as the standard ones of Cattell and Guilford. There is a comparative study of the Eysenck, Cattell and Guilford inventories, which analyses the degree to which similar factors can be found in these three instruments and discusses areas of agreement and disagreement between the three authors. The third part deals with personality studies in children, and includes a chapter on personality structure in subnormal subjects. These studies are concerned with discovering the extent to which personality structure changes with increasing age, and to what extent it is possible to measure personality in younger children. They also examine sex differences in personality structure, and show quite marked differences between the sexes on a number of primary personality traits.

The results of the Eysencks work in this field directed new light on the structure of personality and cast doubt on many widely accepted findings of the time."

Originally published in 1960 these two volumes report a number of experiments in psychogenetics, psychopharmacology, psychodiagnostics, psychometrics and psychodynamics, all of which formed part of the programme of research which had been developing from the late 1940s at the Maudsley Hospital. Presenting the studies together in a book, rather than the more usual route of journal articles, was itself felt to be an experiment at the time, especially given the wide area covered. The decision was deliberate because all the studies reported formed part of a larger whole, which would have been lost if published separately.

Volume II looks at psychodiagnostics, psychodynamics and psychometrics.

The self psychology of Heinz Kohut has been an important force in contemporary psychoanalytic thought and its ramifications for therapy have been extensively explored. Now, Marshall Silverstein offers the first analysis of the application of self psychology to projective diagnostic assessment. Differentiating the self psychological approach from an ego psychological interpretation of classical drive theory, he clearly outlines the principal contributions of Kohut, including the concepts of selfobject functions, empathy, transmuting internalization, and compensatory structure. Providing numerous clinical examples, he shows how the major selfobject functions of mirroring, idealization, and twinship can be identified on projective tests. Silverstein then demonstrates how conventional assessment approaches to grandiosity, self-esteem, and idealization can be reconceptualized within the framework of self psychology, and he also contrasts ego psychological interpretations with self psychological interpretations. This book makes a strong case for the importance of the clinical identification of self states.It will help practitioners understand their patients' varied attempts to repair an injury to the self to restore self-esteem (compensatory structure) and the clinical consequences of self-disorders, including disintegration products such as narcissistic rage and affect states characterized by empty depression, chronic boredom, and lack of zest.

Originally published in 1979, this title represents a summary of 17 years of research centring around the "Sensation Seeking Scale" (SSS) and the theory from which the test was derived. Now an integral part of personality testing, including adaptations for use with children, this reissue is a chance to see where it all began.

The book covers the topic of experimental instrumentation at the turn of the 20th century. The authors introduce the role of instruments in the process of establishing psychology as a science. They concentrate on identifying historical devices and problems with rediscovering their functionality. The core of the book consists of a categorized list of instruments with a description of their purpose and mechanical design. The categorization covers recording and time measuring devices, instruments designated for the research of human senses, memory and learning, and devices for physiological measurement. The publication also includes a companion website with short videos demonstrating selected instruments in action.

In a managed care era, the MMPI-2 is becoming an overloaded workhorse, required to generate more and more of the assessments that a battery of instruments once did. Though all now rely on the MMPI-2 for good reasons, and the MMPI has fallen out of use entirely, some important and clinically useful scales were lost in the transition. Edward Gotts and Thomas Knudsen have recovered these scales and integrated them with all the standard MMPI-2 scales, the recently published Restructured Clinical Scales, and a number of scales they have constructed to assess positive strengths and coping abilities, and response consistency-inconsistency. This book lays out their new Content Cluster interpretive approach. Drawing on data from a large psychiatric inpatient sample, they present item composition, reliability, and validity information for each recovered and new scale, and convincingly demonstrate that their new Content Cluster approach results in improved prediction and interpretive power. They also show how to conjoin Rorschach and MMPI-2 results in more effective assessment strategies, and how to tie MMPI-2 results to specific DSM-IV criteria. The Clinical Interpretation of the MMPI-2: A Content Cluster Approach offers psychologists essential new tools for clinical and personality assessment.

The first edition of Personality Assessment provided an overview of the most popular self-report and performance-based personality assessment instruments. The chapter authors were key members in creating or developing the research base for the eight test instruments covered in the book. The text was geared with graduate-level clinical, school, and counseling psychology courses in mind. While still retaining all the attractive features of the first edition, this revision will reflect the advances in the field since 2008. Chapter contributors updated and expanded on reliability and validity data, clinical utility, multicultural considerations, and implications for therapeutic assessment. Another distinctive feature of this second edition is a companion website that features ancillary materials such as PowerPoints and test banks.

The goal of the chapters in this SIOP Organizational Frontiers Series volume is to challenge researchers to break away from the rote application of traditional methodologies and to capitalize upon the wealth of data collection and analytic strategies available to them. In that spirit, many of the chapters in this book deal with methodologies that encourage organizational scientists to re-conceptualize phenomena of interest (e.g., experience sampling, catastrophe modeling), employ novel data collection strategies (e.g., data mining, Petri nets), and/or apply sophisticated analytic techniques (e.g., latent class analysis). The editors believe that these chapters provide compelling solutions for the complex problems faced by organizational researchers.

This book is an interdisciplinary guide to empirical research on nonverbal behaviour. It focuses on tools and procedures to investigate body movement and gesture and the relation to cognitive, emotional, and interactive processes. NEUROGES is an objective and reliable coding system for movement behaviour and gesture. Its combination with the multi-media annotation tool ELAN results in an effective movement analysis. Rater training and rating procedures constitute an important component in movement behaviour studies. A novel algorithm assesses interrater agreement for the segmentation of the ongoing flow of behaviour. Recommendations for study designs and statistical data evaluation are given, including innovative procedures for the analysis of interactive partners' body movements.

In this volume prominent scholars from both psychology and education describe how these new rules of measurement work and how they differ from the old rules. Several contributors have been involved in the recent construction or revision of a major test, while others are well-known for their theoretical contributions to measurement. The goal is to provide an integrated yet comprehensive reference source concerned with contemporary issues and approaches in testing and measurement.

This book presents original, empirical data from quantitative and qualitative research studies in the field of language learning aptitude, ability, and individual differences. It does so from the perspectives of Second Language Acquisition, psychology, neuroscience and sociolinguistics. All studies included in the book use a similar and uniform layout and methodology. Each chapter contains a study examining factors such as memory, personality, self-concept, bilingualism and multilingualism, education, musicality or gender. The chapters investigate the influence of these concepts on language learning aptitude and ability. Several of these chapters analyse hypotheses which have never been tested before and therefore provide novel research results. The book contributes to the field both by verifying and contesting existent findings and by exploring novel approaches to devising research in the subject area.

Aeromedical psychology is that branch of psychology pertaining to the assessment, selection and evaluation of aviation personnel. This book, Aeromedical Psychology, is designed to provide the means for a variety of clinicians to carry out sound assessment and selection procedures, perform informed evaluations and make subsequent recommendations regarding flight status and treatment strategies geared to the aviation environment. To facilitate a dynamic understanding of the field, the book emphasizes an integration of applications and theory, case examples and research. The book is divided into three parts. The first presents assessment and selection procedures for aviation personnel (i.e. air traffic controllers, flight officers and pilots) and astronauts and the many ways in which both psychologists and psychiatrists are involved in these roles. In the second part, the waiver standards put forth by both the FAA and the various branches of the military are presented, as well as the waiver decision process. Clinical issues unique to aviation - notably fear of flying, motivation to fly and airsickness - are addressed, as well as possible courses of intervention, treatment and disposition. In the final part, more specialized issues pertaining to aeromedical psychology are dealt with, namely the psychopharmacological research and regulations applicable to recreational pilots and aviation personnel, managing the aftermath of aviation mishaps and the psychologist's role in accident investigations.

In recent years, scholars in the fields of refugee studies and forced migration have extended their areas of interest and research into the phenomenon of displacement, human response to it, and ways to intervene to assist those affected, increasingly focusing on the emotional and social impact of displacement on refugees and their adjustment to the traumatic experiences. In the process, the positive concept of "psychosocial wellness" was developed as discussed in this volume. In it noted scholars address the strengths and limitations of their investigations, citing examples from their work with refugees from Afghanistan, Cambodia, Vietnam, Palestine, Cuba, Nicaragua, Haiti, Eastern Europe, Bosnia, and Chile. The authors discuss how they define "psychosocial wellness," as well as the issues of sample selection, measurement, reliability and validity, refugee narratives and "voices," and the ability to generalize findings and apply these to other populations. The key question that has guided many of these investigations and underlies the premise of this book is "what happens to an ordinary person who has experienced an extraordinary event?" This volume also highlights the fact that those involved in such research must also deal with their own emotional responses as they hear victims tell of killing, torture, humiliation, and dispossesion. The volume will therefore appeal to practitioners of psychology, psychiatry, social work, nursing, and anthropology. However, its breadth and the evaluation of the strengths and disadvantages of both qualitative and quantitative methods also make it an excellent text for students.

Since its creation more than eighty years ago, the famous Rorschach inkblot test has become an icon of clinical psychology and popular culture. Administered over one million times world-wide each year, the Rorschach is used to assess personality and mental illness across a wide range of circumstances: child custody disputes, educational placement decisions, employment and termination proceedings, parole determinations, and even investigations of child abuse allegations. The test's enormous power shapes the lives of hundreds of thousands of people -- often without their knowledge. In the 1970s, this notoriously subjective test was supposedly systematized and improved. But is the Rorschach more than a modern variant on tea leaf reading?

"What's Wrong With the Rorschach?" challenges the validity and utility of the Rorschach and explains why psychologists continue to judge people by their reactions to ink blots, in spite of a half century of largely negative scientific evidence.

"What's Wrong With the Rorschach?" offers a provocative critique of one of the most widely applied and influential - and still intensely controversial - psychological tests in the world today. Surveying more than fifty years of clinical and scholarly research, the authors provide compelling scientific evidence that the Rorschach has relatively little value for diagnosing mental illness, assessing personality, predicting behavior, or uncovering sexual abuse or other trauma. In this highly engaging, novelistic account of the Rorschach's origins and history, the authors detail the wealth of scientific evidence that the test is of questionable utility for real-world decision making.

"What's Wrong With the Rorschach?" presents a powerfully reasoned case against using the test in the courtroom or consulting room - and reveals the strong psychological, economic, and political forces that continue to support the Rorschach despite the research that has exposed its shortcomings and dangers.

Contemporary Psychometrics features cutting edge chapters organized in four sections: test theory, factor analysis, structural equation modeling, and multivariate analysis. The section on test theory includes topics such as multidimensional item response theory (IRT), the relationship between IRT and factor analysis, estimation and testing of these models, and basic measurement issues that are often neglected. The factor analysis section reviews the history and development of the model, factorial invariance and factor analysis indeterminacy, and Bayesian inference for factor scores and parameter estimates. The section on structural equation modeling (SEM) includes the general algebraic-graphic rules for latent variable SEM, a survey of goodness of fit assessment, SEM resampling methods, a discussion of how to compare correlations between and within independent samples, dynamic factor models based on ARMA time series models, and multi-level factor analysis models for continuous and discrete data. The final section on multivariate analysis includes topics such as dual scaling of ordinal data, model specification and missing data problems in time series models, and a discussion of the themes that run through all multivariate methods. This tour de force through contemporary psychometrics will appeal to advanced students and researchers in the social and behavioral sciences and education, as well as methodologists from other disciplines.

In this volume, a diverse group of world experts in personality assessment showcase a range of different viewpoints on response distortion. Contributors consider what it means to "fake" a personality assessment, why and how people try to obtain particular scores on personality tests, and what types of tests people can successfully manipulate. The authors present and discuss the usefulness of a range of traditional and cutting-edge methods for detecting and controlling the practice of faking. These methods include social desirability (lie) scales, warnings, affective neutralization, unidimensional and multidimensional pairwise preferences, decision trees, linguistic analysis, situational measures, and methods based on item response theory. The wide range of viewpoints presented in this book are then summarized, synthesized, and evaluated. The authors make practical recommendations and suggest areas for future research. Anyone who wonders whether people exaggerate or lie outright on personality tests -- or questions what psychologists can and should do about it -- will find in this book stimulating questions and useful answers.

Pain is an unfortunate daily experience for many individuals. Chronic pain -- lasting six or more months -- is suffered by approximately 30% of the population in the United States. These individuals wake up, function during the day and go to sleep, trying to keep pain at a minimum while, at the same time, maintaining some quality of life. They may make frequent visits to the doctor and the pharmacy. When they find relief, it is usually short-lived and comes at a cost such as dependence on narcotic medications or complete limitation of activity. Pain often becomes the central point of their existence. This practice guide describes an approach to psychological evaluation of the chronic pain patient who is being considered for surgery. A large body of research is accumulating which demonstrates that the outcome of surgical procedures aimed at chronic pain relief can be strongly influenced by psychological and emotional factors. This approach, termed "presurgical psychological screening" (PPS) uses interview and testing techniques to identify emotional, behavioral, and psychosocial difficulties which have been demonstrated to negatively impact surgical outcome. Studies show that even patients with clearly identifiable pathophysiology may respond poorly to surgery, due to issues such as pain sensitivity, medication dependence, rewards for pain behavior and personality style. Thus, some insurance carriers, rehabilitation nurses and state worker's compensation systems are encouraging, or even requiring, presurgical psychological screening in cases of surgery designed to relieve chronic pain. The first to present a comprehensive, unified approach to PPS in chronic pain syndromes, this text is designed to provide the behavioral health practitioner, as well as the trainee, with all the tools and information necessary to conduct PPS evaluations. It identifies a multitude of risk factors for poor surgical outcome and reviews research associated with each risk factor. Hands-on techniques for eliciting information from the patient about risk factors is also detailed. Toward this end, the practice guide also contains a number of forms and session outlines which can be directly utilized, or which can be altered to fit readers' needs. Models for weighing and combining surgical outcome risk factors are also provided. Thus, practitioners are able to reach valid and reliable predictions of surgical results. Finally, the text provides outlines of psychological interventions which can facilitate surgical outcome as well as surgical treatment alternatives. Upon completion of this practice guide, readers should be able to begin providing PPS evaluations which are scientifically valid, clinically sound, and which result in significant overall improvement in the treatment of chronic pain syndromes.

WISC-V: Clinical Use and Interpretation, Second Edition provides practical information for clinicians on the selection of subtest measures, along with their proper administration and interpretation. Full Scale IQ is identified as important for predicting relevant behaviors and primary index scores for characterizing the child's strengths and weaknesses. Classroom indicators of low scores on each of these abilities are identified, with suggested interventions, accommodations and instructional strategies for low scorers. Coverage includes ethnic differences for the Full Scale IQ and each primary index score, along with evidence of the profound influence of parental attitudes and expectations. Several other societal and contextual factors relevant to understanding racial/ethnic differences are presented. Two chapters review use of the WISC-V for identifying learning disabilities, testing of individuals with dyslexia, and best-practice recommendations to ensure accurate diagnosis and intervention. Concluding chapters describe advances in the Q-interactive system platform allowing administration of the WISC-V on iPads and other tablets, and how clinicians can tailor assessment using select WISC-V subtests and features.

This book reviews the statistical procedures used to detect measurement bias. Measurement bias is examined from a general latent variable perspective so as to accommodate different forms of testing in a variety of contexts including cognitive or clinical variables, attitudes, personality dimensions, or emotional states. Measurement models that underlie psychometric practice are described, including their strengths and limitations. Practical strategies and examples for dealing with bias detection are provided throughout. The book begins with an introduction to the general topic, followed by a review of the measurement models used in psychometric theory. Emphasis is placed on latent variable models, with introductions to classical test theory, factor analysis, and item response theory, and the controversies associated with each, being provided. Measurement invariance and bias in the context of multiple populations is defined in chapter 3 followed by chapter 4 that describes the common factor model for continuous measures in multiple populations and its use in the investigation of factorial invariance. Identification problems in confirmatory factor analysis are examined along with estimation and fit evaluation and an example using WAIS-R data. The factor analysis model for discrete measures in multiple populations with an emphasis on the specification, identification, estimation, and fit evaluation issues is addressed in the next chapter. An MMPI item data example is provided. Chapter 6 reviews both dichotomous and polytomous item response scales emphasizing estimation methods and model fit evaluation. The use of models in item response theory in evaluating invariance across multiple populations is then described, including an example that uses data from a large-scale achievement test. Chapter 8 examines item bias evaluation methods that use observed scores to match individuals and provides an example that applies item response theory to data introduced earlier in the book. The book concludes with the implications of measurement bias for the use of tests in prediction in educational or employment settings. A valuable supplement for advanced courses on psychometrics, testing, measurement, assessment, latent variable modeling, and/or quantitative methods taught in departments of psychology and education, researchers faced with considering bias in measurement will also value this book.

Individual Differences and Personality provides a student-friendly introduction to both classic and cutting-edge research into personality, mood, motivation and intelligence, and their applications in psychology and in fields such as health, education and sporting achievement. Including a new chapter on 'toxic' personality traits, and an additional chapter on applications in real-life settings, this fourth edition has been thoroughly updated and uniquely covers the necessary psychometric methodology needed to understand modern theories. It also develops deep processing and effective learning by encouraging a critical evaluation of both older and modern theories and methodologies, including the Dark Triad, emotional intelligence and psychopathy. Gardner's and hierarchical theories of intelligence, and modern theories of mood and motivation are discussed and evaluated, and the processes which cause people to differ in personality and intelligence are explored in detail. Six chapters provide a non-mathematical grounding in psychometric principles, such as factor analysis, reliability, validity, bias, test-construction and test-use. With self-assessment questions, further reading and a companion website including student and instructor resources, this is the ideal resource for anyone taking modules on personality and individual differences.

How do we measure happiness? Focusing on subjective measures as a proxy for welfare and well-being, this book finds ways to do that. Subjective measures have been used by psychologists, sociologists, political scientists, and, more recently, economists to answer a variety of scientifically and politically relevant questions. Van Praag, a pioneer in this field since 1971, and Ferrer-i-Carbonell present in this book a generally applicable methodology for the analysis of subjective satisfaction. Drawing on a range of surveys on people's satisfaction with their jobs, income, housing, marriages, and government policy, among other areas of life, this book shows how satisfaction with life "as a whole" is an aggregate of these domain satisfactions. Using German, British, Dutch, and Russian data, the authors cover a wide range of topics, even some not usually considered part of economic study. The book makes a distinction between actual satisfaction levels and individual norms, and in this way complements Van Praag's earlier work within the Leyden School with his later work in "happiness research". Among the many topics covered, the authors discuss: individuals' memory and anticipation processes and the estimation of adaptation phenomena (how individuals adapt to changing circumstances); the effect of reference groups on income norms and satisfaction with income; the importance of climate for well-being, including the development of a climate-equivalence index; the trade-offs between chronic diseases and income when well-being is kept constant; the damage of aircraft noise on well-being; the construction of a new talent tax tariff; and inequality from a satisfaction perspective, including the definition of "satisfaction inequalities", a natural extension of income inequality and poverty. This groundbreaking book presents new and fruitful methodology that consitutes a welcome addition to the social sciences.

This comprehensive Handbook focuses on the most used polytomous item response theory (IRT) models. These models help us understand the interaction between examinees and test questions where the questions have various response categories. The book reviews all of the major models and includes discussions about how and where the models originated, conceptually and in practical terms. Diverse perspectives on how these models can best be evaluated are also provided. Practical applications provide a realistic account of the issues practitioners face using these models. Disparate elements of the book are linked through editorial sidebars that connect common ideas across chapters, compare and reconcile differences in terminology, and explain variations in mathematical notation. These sidebars help to demonstrate the commonalities that exist across the field. By assembling this critical information, the editors hope to inspire others to use polytomous IRT models in their own research so they too can achieve the type of improved measurement that such models can provide.

Part 1 examines the most commonly used polytomous IRT models, major issues that cut across these models, and a common notation for calculating functions for each model. An introduction to IRT software is also provided. Part 2 features distinct approaches to evaluating the effectiveness of polytomous IRT models in various measurement contexts. These chapters appraise evaluation procedures and fit tests and demonstrate how to implement these procedures using IRT software. The final section features groundbreaking applications. Here the goal is to provide solutions to technical problems to allow for the most effective use of these models in measuring educational, psychological, and social science abilities and traits. This section also addresses the major issues encountered when using polytomous IRT models in computerized adaptive testing. Equating test scores across different testing contexts is the focus of the last chapter. The various contexts include personality research, motor performance, health and quality of life indicators, attitudes, and educational achievement.

Featuring contributions from the leading authorities, this handbook will appeal to measurement researchers, practitioners, and students who want to apply polytomous IRT models to their own research. It will be of particular interest to education and psychology assessment specialists who develop and use tests and measures in their work, especially researchers in clinical, educational, personality, social, and health psychology. This book also serves as a supplementary text in graduate courses on educational measurement, psychometrics, or item response theory.

This is a reprint of the orginal book released in 1968. Our primary goal in this book is to sharpen the skill, sophistication, and in- tuition of the reader in the interpretation of mental test data, and in the construction and use of mental tests both as instruments of psychological theory and as tools in the practical problems of selection, evaluation, and guidance. We seek to do this by exposing the reader to some psychologically meaningful statistical theories of mental test scores. Although this book is organized in terms of test-score theories and models, the practical applications and limitations of each model studied receive substantial emphasis, and these discussions are presented in as nontechnical a manner as we have found possible. Since this book catalogues a host of test theory models and formulas, it may serve as a reference handbook. Also, for a limited group of specialists, this book aims to provide a more rigorous foundation for further theoretical research than has heretofore been available.One aim of this book is to present statements of the assumptions, together with derivations of the implications, of a selected group of statistical models that the authors believe to be useful as guides in the practices of test construction and utilization. With few exceptions we have given a complete proof for each major result presented in the book. In many cases these proofs are simpler, more complete, and more illuminating than those originally offered. When we have omitted proofs or parts of proofs, we have generally provided a reference containing the omitted argument. We have left some proofs as exercises for the reader, but only when the general method of proof has already been demonstrated. At times we have proved only special cases of more generally stated theorems, when the general proof affords no additional insight into the problem and yet is substantially more complex mathematically.
