This volume provides an in-depth examination of traditional and emerging measures of attachment behavior and representations from infancy to adulthood. Leading authorities share their expertise on the Strange Situation, the Attachment Q-set, Ainsworth's Maternal Sensitivity Scales, the Adult Attachment Interview, the Attachment Script Assessments, and the Adult Attachment Projective Picture System, as well as analogue and experimental methods. The book clarifies the conceptual and empirical underpinnings of the various measures and shows how they fit into a coherent developmental framework. Offering detailed discussions of key constructs such as attachment security, the secure base phenomenon, disorganization, and narrative structure, this is a valuable resource for both researchers and practitioners who use attachment assessments in their work.

This book provides an alternative method for measuring individual differences in psychological, educational, and other behavioral sciences studies. It is based on the assumptions of ordinal statistics as explained in Norman Cliff's 1996 "Ordinal Methods for Behavioral Data Analysis." It provides the necessary background on ordinal measurement to permit its use to assess psychological and psychophysical tests and scales and interpret the data obtained. The authors believe that some of the behavioral measurement models used today do not fit the data or are inherently self-contradictory. Applications of these models can therefore lead to unwarranted inferences regarding the status of the derived variables. These methods can also be difficult to apply, particularly in small-sample contexts without making additional, unrealistic assumptions. Ordinal methods more closely reflect the original data, are simple to apply, and can be used in samples of any size. The book's approach is in essence a return to simple empiricism in psychological measurement.
"Ordinal Measurement in the Behavioral Sciences" provides:
*methods for analyzing test responses;
*extensive discussions of ordinal approaches to analyzing data that are judgments of stimuli;
*methods for treating psychological data in ways consistent with its ordinal nature so as to stimulate new developments in this area; and
*ordinal test theory and the unfolding methods that are applicable to cross-cultural studies.
Advanced students, researchers, and practitioners concerned with psychological measurement should find this book relevant. Measurement professionals will find it provides useful and simple methods that stimulate thought about measurement's real issues.

Recognised as the most influential publication in the field, ARM facilitates deep understanding of the Rasch model and its practical applications. The authors review the crucial properties of the model and demonstrate its use with examples across the human sciences.

The glossary and illustrations support that understanding, and the accessible approach means that it is ideal for readers without a mathematical background.

Highlights of the new edition include:

• More learning tools to strengthen readers’ understanding including chapter introductions, boldfaced key terms, chapter summaries, activities and suggested readings.
• Greater emphasis on the use of R packages; readers can download the R code from the Routledge website.
• Explores the distinction between numerical values, quantity and units, to understand the measurement and the role of the Rasch logit scale (Chapter 4).
• A new four-option data set from the IASQ (Instrumental Attitude towards Self-assessment Questionnaire) for the Rating Scale Model (RSM) analysis exemplar (Chapter 6).
• Clarifies the relationship between Rasch measurement, path analysis and SEM, with a host of new examples of Rasch measurement applied across health sciences, education and psychology (Chapter 10).

Intended as a text for graduate courses in measurement, item response theory, (advanced) research methods or quantitative analysis taught in psychology, education, human development, business, and other social and health sciences. Professionals in these areas will also appreciate the book’s accessible introduction.

Essentials of Rorschach Assessment provides an invaluable resource for clinicians, offering the only step-by-step guidance toward all aspects of the Rorschach Comprehensive System and Rorschach Performance Assessment System (R-PAS). Beginning with an overview of the tests' history and development, the discussion delves into each test separately before placing the two side by side for direct comparison of administration, coding, and interpretation. The same case study is used for both tests, providing a start-to-finish example of how the Comprehensive System and R-PAS differ, and practical resources including checklists, charts, and sample forms help ease implementation, use, and transition. Thorough explanations break down the jargon and technical language to give clinicians a clearer understanding of both tests without sacrificing precision or depth of information, providing a quick and easy reference for Rorschach personality assessment.

This edited volume presents a balanced approach to the ongoing debate of just how general the "general factor" of intelligence is. To accomplish this goal, the editors chose a number of distinct approaches to the study of intelligence--psychometric, genetic-epistemological, cognitive, biological, behavior-genetic, sociocultural, systems--and asked distinguished scholars to write from the standpoint of these approaches. Each approach comprises two chapters, one by a scholar leaning toward a view arguing for the greater generality of "g," and the other by a scholar leaning toward a view arguing for the lesser generality of "g." The scholars are not simply "for" or "against" these outlooks, rather they provide a more textured view of the general factor, attempting to explain it in psychological terms that are easily understandable.
Intended for psychologists in all areas, including clinical, consulting, educational, cognitive, school, developmental, and industrial-organizational, this book will also be of interest to educators, sociologists, anthropologists, and those interested in the nature of intelligence.

Quickly acquire the knowledge and skills you need to confidently administer, score, and interpret the PAI

The Personality Assessment Inventory (PAI) provides critical information for psychologists about a client’s psychopathology and constructs for effective treatment. To use this test properly, professionals need an authoritative source of advice and guidance on how to administer, score, and interpret the test. Written by the developer and foremost authority on the PAI, Essentials of PAI Assessment is that source.

Like all the volumes in the Essentials of Psychological Assessment series, this book is designed to help busy mental health professionals quickly acquire the knowledge and skills they need to make optimal use of major psychological assessment instruments. Each concise chapter features numerous callout boxes highlighting key concepts, bulleted points, and extensive illustrative material, as well as test questions that help you gauge and reinforce your grasp of the information covered.

Essentials of PAI Assessment is the only concise book of its kind to provide state-of-the-art interpretive and administrative guidelines to using this popular self-administered personality test.

A collection of illustrative adolescent case studies to aid clinicians in problem identification, diagnosis, and treatment planning-the only casebook for the MMPI-A-RF The MMPI-A-RF is linked to current models of psychopathology and personality, and features scales relevant for use with adolescents in a variety of clinical, forensic, and school settings. It mirrors the structure of the MMPI-2-RF, resulting in the most up-to-date, empirically based personality assessment for use with adolescents. Written by the authors of the earlier Case Studies for Interpreting the MMPI-A, this book continues the goal of serving as an authentic and illustrative guide for clinicians in understanding and using the MMPI-A-RF. Since the publication of the original Case Studies, much has changed for clinicians who assess and treat adolescents. The interpretive model described in this book demonstrates how the MMPI-A-RF can assist clinicians in assessing youth today by highlighting sixteen cases that broadly represent adolescents evaluated in clinical and forensic practice. In addition, one of the most common uses for the MMPI-A-RF is in the juvenile court setting-a landscape that has also dramatically changed since the publication of the original MMPI-A. Case Studies for Interpreting the MMPI-A-RF focuses on detailed forensic issues, including legal backgrounds, case law, and assessment methods specific to use of the MMPI-A-RF in juvenile court and related settings. Case Studies for Interpreting the MMPI-A-RF will assist clinicians in understanding MMPI-A-RF interpretation, while also being a valuable teaching tool for courses in assessment.

Why are some people more mentally able than others ? In an authoritative, critical and intergrated series of review essays Professor Ian Deary inquires after the cognitive and biological foundations of human mental ability differences. Many accounts of intelligence have examined the structure and number of human mental ability differences and whether they can predict sucess in education,work and social life. Few books have taken psychometric intelligence differences as a starting point and brought together the reductionistic attempts to explain them.New to the highly acclaimed Oxford Psychology Series, Looking Down on Human Intelligence appraises the search for the origins of psychometric intelligence differences in terms of brain function parameters. The book provides an original and thought provoking guide to ancient and modern research on one of the most compelling questions in human psychology.

Quickly acquire the knowledge and skills you need to confidently administer, score, and interpret the MBTI

In order to use the Myers-Briggs Type Indicator (MBTI) appropriately and effectively, professionals need an authoritative source of advice and guidance on how to administer, score, and interpret this test. Written by Naomi Quenk--who coauthored the 1998 revision of the "MBTI Manual" and the "MBTI Step II Manual--Essentials of Myers-Briggs Type Indicator Assessment, Second Edition" is that source.

Like all the volumes in the "Essentials of Psychological Assessment" series, this book is designed to help busy practitioners, and those in training, to quickly acquire the knowledge and skills they need to make optimal use of major psychological assessment instruments. Each concise chapter features numerous callout boxes highlighting key concepts, bulleted points, and extensive illustrative material, as well as test questions that help you gauge and reinforce your grasp of the information covered.

Completely revised and up to date with discussion of new versions of the MBTI, such as MBTI Step II and MBTIComplete, "Essentials of Myers-Briggs Type Indicator Assessment," Second Edition provides expert assessment of the instrument's relative strengths and weaknesses, valuable advice on its clinical applications, and several illuminating case reports.

Post-traumatic stress disorder (PTSD) is a serious and sometimes debilitating mental disorder. Yet only about one in ten people who are exposed to significant traumatic events develop PTSD. Since its inclusion in the Diagnostic and Statistical Manual (DSM) in 1980, the definition of PTSD has been controversial. Various changes made to the criteria have gradually widened the diagnostic criteria, which now include experiences that may not involve direct exposure to trauma, which in turn has led to PTSD to be over-diagnosed: clinicians may be tempted to seize on traumatic events in a history as an explanation of mental disorders, while patients may automatically receive the diagnosis if they experienced major trauma in the past. Myths of Trauma is a timely and important book that probes the sensitive, emotional, and often controversial subject of trauma, the difficulties associated with its diagnosis, and the over-diagnosis of PTSD. Trauma has become a catch-all for many kinds of adverse experiences, when in reality, people are significantly resilient to traumatic events. The book also explores how responses to trauma develop in the context of multiple interwoven risk factors, ranging from genetic vulnerability effecting sensitivity to the environment, as well as past adversities; how trauma has become a political issue that interferes with unbiased scientific study of its effects; and how trauma narratives can have a darker side when patients use them to justify feelings of victimhood that interfere with their own agency. Integrating and analysing the vast quantities of scientific literature on the topic, Myths of Trauma teaches us not to think about trauma in isolation or as one thing rather than many different things. The experiences of trauma deserve a place in clinical practice, and it is time for PTSD to be viewed through a more complex and multidimensional lens within the broader biopsychosocial context.

The field of mathematical psychology began in the 1950s and includes both psychological theorizing, in which mathematics plays a key role, and applied mathematics motivated by substantive problems in psychology. Central to its success was the publication of the first Handbook of Mathematical Psychology in the 1960s. The psychological sciences have since expanded to include new areas of research, and significant advances have been made in both traditional psychological domains and in the applications of the computational sciences to psychology. Upholding the rigor of the original Handbook, the New Handbook of Mathematical Psychology reflects the current state of the field by exploring the mathematical and computational foundations of new developments over the last half-century. The second volume focuses on areas of mathematics that are used in constructing models of cognitive phenomena and decision making, and on the role of measurement in psychology.

This book focuses on the practical application of statistical techniques for assessing measurement invariance with less emphasis on theoretical development or exposition. Instead, it describes the methods using a pedagogical framework followed by extensive illustrations that demonstrate how to use software to analyze real data. The chapters illustrate the practical methods to assess measurement invariance and shows how to apply them to a range of data.

This book examines the principles and practice of authentic assessment. It seeks to answer the following questions. What is authentic assessment? How is authentic assessment different from 'performance assessment' or 'alternative assessment'? How can authentic assessment support learner-centred education, especially when a performance-oriented culture favours pen-and-paper examinations? The book is structured into two major parts. The first, 'Principles of authentic assessment design', provides readers with a conceptual explanation of authenticity; the principles for designing quality authentic assessments for valid evidence of student learning; and guidance about how to develop quality rubrics to structure assessment tasks. The second part of the book, 'Theory into practice' provides examples developed by teachers to demonstrate an understanding of authentic assessment. The subject areas covered include humanities, languages, mathematics, sciences, character and citizenship. Two case studies are discussed to demonstrate how authentic assessment can be used to comprehensively address key learning objectives in a variety of curriculum contexts. This book provides practitioners with concrete examples on how to develop authentic assessment to suit their context and also enhance their students' learning. The book will also enable teachers to face assessment challenges present in our changing world.

An Introduction to Psychometrics and Psychological Assessment is the successor to Cooper’s prize-winning book Psychological Testing: Theory and Practice. This expanded and updated volume shows how psychological questionnaires and tests can be chosen, administered, scored, interpreted and developed. In providing students, researchers, test users, test developers and practitioners in the social sciences, education and health with an evaluative guide to choosing, using, interpreting and developing tests, it provides readers a thorough grasp of the principles (and limitations) of testing, together with the necessary methodological detail.

This book has three distinctive features. First, it stresses the basic logic of psychological assessment without getting bogged down with mathematics; the spreadsheet simulations and utilities which are integrated into the text allow users to explore how numbers behave, rather than reading equations. Readers will "learn by doing". Second, it covers both the theory behind psychological assessment and the practicalities of locating, designing and using tests and interpreting their scores. Finally, it is evaluative. Rather than just describing concepts such as test reliability or adaptive testing, it stresses the underlying principles, merits and drawbacks of each approach to assessment, and methods of developing and evaluating questionnaires and tests. Unusually for an introductory text, it includes coverage of several cutting-edge techniques, and this new edition expands the discussion on measurement invariance, methods of detecting/quantifying bias and hierarchical factor models, and features added sections on:

Best practices for translation of tests into other languages and problems of cultural bias

Automatic item generation

The advantages, drawbacks and practicalities of internet-based testing

Generalizability theory

Network analysis

Dangerous assumptions made when scoring tests

The accuracy of tests used for assessing individuals

The two-way relationship between psychometrics and psychological theory

Aimed at non-mathematicians, this friendly and engaging text will help you to understand the fundamental principles of psychometrics that underpin the measurement of any human characteristic using any psychological test. Written by a leading figure in the field and accompanied by additional resources, including a set of spreadsheets which use simulated data and other techniques to illustrate important issues, this is an essential introduction for all students of psychology and related disciplines. It assumes very little statistical background and is written for students studying psychological assessment or psychometrics, and for researchers and practitioners who use questionnaires and tests to measure personality, cognitive abilities, educational attainment, mood or motivation.

A SPECTATOR BOOK OF THE YEAR 'History that reads like biography that reads like a novel - a fluid narrative that defies expectations and plays against type' New York Times 'Brilliant and savage' Philip Hensher An unprecedented history of the personality test conceived a century ago by a mother and her daughter - fiction writers with no formal training in psychology - and how it insinuated itself into our boardrooms, classrooms, and beyond. The Myers-Briggs Type Indicator is the most popular personality test in the world. It has been harnessed by Fortune 100 companies, universities, hospitals, churches, and the military. Its language - of extraversion vs. introversion, thinking vs. feeling - has inspired online dating platforms and Buzzfeed quizzes alike. And yet despite the test's widespread adoption, experts in the field of psychometric testing, a $500 million industry, struggle to account for its success - no less validate its results. How did the Myers-Briggs insinuate itself into our jobs, our relationships, our internet, our lives? First conceived in the 1920s by the mother-daughter team of Katherine Briggs and Isabel Briggs Myers, a pair of aspiring novelists and devoted homemakers, the Myers-Briggs was designed to bring the gospel of Carl Jung to the masses. But it would take on a life of its own, reaching from the smoke-filled boardrooms of mid-century New York to Berkeley, California, where it was honed against some of the 20th century's greatest creative minds. It would travel across the world to London, Zurich, Cape Town, Melbourne, and Tokyo; to elementary schools, nunneries, wellness retreats, and the closed-door corporate training sessions of today. Drawing from original reporting and never-before-published documents, What's Your Type? examines nothing less than the definition of the self - our attempts to grasp, categorise and quantify our personalities. Surprising and absorbing, the book, like the test at its heart, considers the timeless question: What makes you you?

How can you discover where your true potential lies? Is it possible to balance work and life more effectively? What has been holding you back? The Complete Personality Assessment uses psychometric and analytical techniques to help you answer all of these questions and more. Consisting of a series of personality tests, motivation tests and competency exercises, it takes a structured approach to help you understand how to control underlying emotions that have been standing in your way. It covers everything you need to realise your full potential, including a career development profile, action plans for change, a life balance test, career motivation test and a competency checklist. With insight and analysis into how can you focus these results for career and personal success, The Complete Personality Assessment reveals the truth about who you really are and what has been standing in your way.

Practice prepare and get ready to pass. Don't let a psychometric test stop you getting the job you want. Packed with practice questions and practical Passing Psychometric Tests will help you lose the fear, prepare and practice with everything you need to know to pass with flying colours.

The field of psychometrics has a long and varied tradition across the social sciences. A range of academics have sought to understand human consciousness more fully by statistical testing our abilities, personalities, attitudes and beliefs. But perhaps the area where psychometric techniques have had most impact on contemporary society is in employee recruitment, where a range of psychometric tests have become common-place. Professor Peter Saville is one of the pioneers of adapting psychometric testing to the field of occupational psychology and human resource management. In a career of nearly 40 years, his work has been adopted by hundreds of public and private organizations, assessing the suitability of prospective candidates through a range of questionnaires and tests. In this anthology of his work, including both keynote conference address and journal papers, Saville provides a masterly overview of the field of psychometrics, and the key issues and questions that it raises. An ideal companion for any student or researcher of HRM, occupational or organizational psychology, or applied psychology in general, Peter Saville's selected works represent the thinking of one of the most influential psychologists of our time.

What makes a fascist? Are there character traits that make someone more likely to vote for the far right? The Authoritarian Personality, written in the shadow of Fascism and the Holocaust, looked to analyse the rise of Fascism in Europe through the specific psychological traits that make people prone to authoritarianism. Based on extensive empirical studies of Americans conducted by a team which included the leading member of the Frankfurt School Theodor Adorno, The Authoritarian Personality ranked a range of character traits on what it called the 'F scale' (F for fascist). These included conventionalism, anti-intellectualism, superstition and occultism, power and toughness, destructiveness and cynicism, projectivity, and exaggerated concerns over sex. The Authoritarian Personality is not only one of the most influential works of social psychology ever written, it also marks a milestone in the development of Adorno's thought, showing him grabbling with the problem of fascism and the reasons for Europe's turn to reaction. Over half a century later and with the rise of right-wing populism and the reemergence of the far-right in recent years, this hugely influential study remains as insightful and relevant as ever.

This book introduces multidimensional scaling (MDS) and unfolding as data analysis techniques for applied researchers. MDS is used for the analysis of proximity data on a set of objects, representing the data as distances between points in a geometric space (usually of two dimensions). Unfolding is a related method that maps preference data (typically evaluative ratings of different persons on a set of objects) as distances between two sets of points (representing the persons and the objects, resp.). This second edition has been completely revised to reflect new developments and the coverage of unfolding has also been substantially expanded. Intended for applied researchers whose main interests are in using these methods as tools for building substantive theories, it discusses numerous applications (classical and recent), highlights practical issues (such as evaluating model fit), presents ways to enforce theoretical expectations for the scaling solutions, and addresses the typical mistakes that MDS/unfolding users tend to make. Further, it shows how MDS and unfolding can be used in practical research work, primarily by using the smacof package in the R environment but also Proxscal in SPSS. It is a valuable resource for psychologists, social scientists, and market researchers, with a basic understanding of multivariate statistics (such as multiple regression and factor analysis).
