Cluster analysis is a multivariate classification technique that
allows for identification of homogenous subgroups within diverse
samples based on shared characteristics. In recent years, cluster
analysis has been increasingly applied to psychological and
neuropsychological variables to address a number of empirical
questions. This book provides an overview of cluster analysis,
including statistical and methodological considerations in its
application to neurobehavioral variables. First, an introduction to
cluster analysis is presented that emphasizes issues of relevance
to neuropsychological research, including controversies surrounding
it use. Cluster analysis is then applied to clinical disorders that
do not have an associated prototypical neuropsychological profile,
including traumatic brain injury, schizophrenia, and health
problems associated with homelessness. In a second application,
cluster analysis is used to investigate the course of normal memory
development. Finally, cluster analysis is applied to classification
of brain injury severity in children and adolescents who sustained
traumatic brain injury.

This book provides a comprehensive introduction to psychological
assessment and covers areas not typically addressed in existing
test and measurements texts, such as neuropsychological assessment
and the use of tests in forensics settings. The book introduces the
vocabulary of the profession and the most basic mathematics of
testing early as being fundamental to understanding the field.
Numerous examples are drawn from tests that the authors have
written or otherwise helped to develop, reflecting the authors'
deep understanding of these tests and their familiarity with
problems encountered in test development, use, and interpretation.
Following the introduction of the basic areas of psychometrics, the
book moves to areas of testing that represent various approaches to
measuring different psychological constructs (memory, language,
executive function, etc.), with emphasis on the complex issue of
cultural bias in testing. Examples of existing tests are given
throughout the book; however, this book is not designed to prepare
students to go out and administer, score, and interpret specific
psychological tests. Rather, the purpose of this book is to provide
the foundational core of knowledge about tests, measurement, and
assessment constructs, issues, and quantitative tools. Explains
what constitutes a psychological test, how tests are developed, how
they are best used, and how to evaluate their strengths and
weaknesses; Describes areas of testing that represent different
approaches to measuring different psychological constructs;
Explains applications of psychological testing to issues in the
courts; Addresses how test authors and publishers design and
research tests to address the difficult and demanding issues of
cultural differences in test performance and interpretation of test
results.

The fourth edition of the Handbook of Psychological Assessment,
provides scholarly overviews of the major areas of psychological
assessment, including test development, psychometrics, technology
of testing, and commonly used assessment measures. Psychological
assessment is included for all ages, with new coverage encompassing
ethnic minorities and the elderly. Assessment methodology discussed
includes formal testing, interviewing, and observation of behavior.
The handbook also discusses assessment of personality and behavior,
including intelligence, aptitude, interest, achievement,
personality and psychopathology. New coverage includes use of
assessments in forensic applications.
In Neuropsychological Aspects of Substance Use Disorders,
internationally recognized experts provide clinicians with the most
up to date information on the neuropsychology of substance use
disorders based on the empirical literature. Substance use
disorders continue to be a major health concern in the United
States and worldwide, although their causes and effective
treatments remain elusive. Research in this area has expanded
dramatically over the past two decades and provided insights into
psychobiological, behavioral, and genetic factors that contribute
to the onset and maintenance of substance use disorders and
associated neuropsychological abnormalities. This research has
provided a strong empirical foundation that has direct implications
for clinical neuropsychological practice and created a need to
provide the practitioner with a cogent and up-to-date summary of
current developments, which is the goal of this volume. Chapters in
this volume are organized into three sections that are designed to
provide a translational overview of basic research and treatment
findings regarding addictions, neuropsychological and neurological
sequalae of the most common substances of abuse, and consideration
of special issues that might confound interpretation of
neuropsychological test results. Section I provides an overview of
addictions, including diagnoses based on the DSM-IV, as well as the
most current conceptualizations of addiction from psychobiological,
genetic, and behavioral and no economics perspectives, providing
the reader with a broad evidence-based conceptual framework.
Section II reviews the most common substances of abuse including
coverage of structural and functional neuroimaging findings,
epidemiological evidence, and neuropsychological sequelae.
Substances included in this section represent the most commonly
encountered drugs of abuse. Section III includes coverage of the
number of special topics, including specific issues related to
psychiatric, medical, and neurological comorbidities. Topics
included in this section represent areas of common concerns faced
by clinical neuropsychologists in the interpretation and
application of neuropsychological test results.
