Stress and reproduction: introduction to the special section.

This special section on stress and reproduction is devoted to an emerging frontier in interdisciplinary research that merits the attention of health psychologists. The majority of the studies concern the role of stress and emotion on birth outcomes such as low birth weight, fetal growth and preterm delivery, or mechanisms underlying these findings. The implications of this research extend from maternal and infant health to life-span development and adult health and mortality.     

Psychological assessment in Asia: introduction to the special section

Psychological assessment with Asians is an important topic not only for psychologists from Asian countries but also for psychologists in multicultural societies with large populations of ethnic Asians. There is a dearth of information in the English language literature on psychological assessment for Asians. This special section is organized to review various forms of psychological assessment in Asia. The objectives of the special section are to inform test users and researchers of the issues related to cross-cultural validity of psychological assessment in Asia and to introduce examples of adapted and indigenously developed instruments that are culturally appropriate.     

Expanding the aperture of psychological assessment: introduction to the special section on innovative clinical assessment technologies and methods

Contemporary psychological assessment is dominated by tried-and-true methods like clinical interviewing, self-report questionnaires, intellectual assessment, and behavioral observation. These approaches have served as the mainstays of psychological assessment for decades. To be sure, these methods have survived over the years because clinicians have found the information gleaned from these improves our understanding of the client, helps formulate a treatment plan, or aids in assessing outcome. However, are there any recent technological or methodological developments that might improve the clinical assessment enterprise? Some believe so. The purpose of this special section is to provide a snapshot of relatively newer clinical assessment technologies and methods that have been underutilized. Each article in this special section presents one or more assessment methods or techniques that are currently available and are showing some promise in clinical assessment.     

Sexual orientation across the life span: introduction to the special section

What impact does sexual orientation have on human development over the life span? As questions related to sexual orientation have become increasingly topics of public discussion and debate in recent years, psychological study of the issues has also burgeoned. What was once a new frontier for research has matured into a large, complex, and rapidly growing area of knowledge. Important research is being conducted on many issues, by diverse investigators, from a number of theoretical perspectives, in many parts of the world. The articles in this special section provide only a sampling of current research, but they begin to suggest the vitality and excitement of a field that is coming into its own.     

Individual differences in working memory: introduction to the special section.

This special section includes a set of 5 articles that examine the nature of inter- and intraindividual differences in working memory, using working memory span tasks as the main research tools. These span tasks are different from traditional short-term memory spans (e.g., digit or word span) in that they require participants to maintain some target memory items (e.g., words) while simultaneously performing some other tasks (e.g., reading sentences). In this introduction, a brief discussion of these working memory span tasks and their characteristics is provided first. This is followed by an overview of 2 major theoretical issues that are addressed by the subsequent articles--(a) the factors influencing the inter- and intraindividual differences in working memory performance and (b) the domain generality versus domain specificity of working memory--and also of some important issues that must be kept in mind when readers try to evaluate the claims regarding these 2 theoretical issues.     

Laboratory and performance-based measures of childhood disorders: introduction to the special section

Serves as an introduction to a special section of the journal on laboratory and performance-based measures of childhood disorders. The articles in the special section were part of the work of a task force established by Division 12 of the American Psychological Association on "Upgrading the Science and Technology of Assessment and Diagnosis." In this introduction, I raise a number of issues involved in the use of laboratory and performance-based measures for the assessment of childhood psychopathology that cut across the different disorders covered in the special section. Some of these issues are common to most techniques used in the assessment of childhood psychopathology; others are more specific to this particular method of assessment. However, by focusing on these issues related to the use of laboratory and performance-based measures, it will hopefully encourage a critical examination of all techniques currently being used in the assessment of psychopathology and highlight important issues involved in translating measures that were developed primarily for use in research into forms that are useful in clinical practice.     

Proposals for DSM-5: introduction to special section of Journal of Personality Disorders

On February 10, 2010, the official proposals for the personality disorders section of the fifth edition of the American Psychiatric Association's (APA) Diagnostic and Statistical Manual of Mental Disorders (DSM-5) were posted (see www.dsm5.org ). The posting by the DSM-5 Personality and Personality Disorders Work Group has been helpful in informing the field of the possible changes that may occur with DSM-5. Their presence allows for and encourages persons to provide their suggestions and concerns. The extent of the proposals is considerable. As expressed on the website, "the work group recommends a major reconceptualization of personality psychopathology" (Skodol, 2010, "Reformulation of personality disorders in DSM-5," para. 1). The proposals have generated some controversy. The Journal of Personality Disorders has always sought to be a participant in the crucial debates in our field. The purpose of this special issue is to provide members of the Work Group the opportunity to further articulate the rationale for the proposals, and to provide others an opportunity to articulate their concerns. Copies of this special issue were distributed to interested persons when the complete set of final papers were received (October of 2010).     

Reconceptualizing personality disorder categories using personality trait dimensions: introduction to special section

The categorical model of personality disorders has been widely criticized, and many argue for it to be reconceptualized or replaced by a dimensional model rooted in personality trait research. Such criticisms have forged a much needed integration between the previously distinct research areas of normal and abnormal personality. The five articles in this special section provide compelling evidence for the usefulness of personality traits for describing and explaining the complexities of personality disorders among widely varying samples using very different assessment strategies.     

Psychosocial factors in the course and treatment of bipolar disorder: introduction to the special section

Bipolar disorder is associated with high rates of relapse and high social and economic costs, even when patients are maintained on proper pharmacotherapy. The background and rationale are offered here for a series of articles that address the role of psychosocial agents in the course of bipolar disorder and psychosocial treatments as adjuncts to pharmacotherapy in the disorder's outpatient maintenance. It is argued that stressful life events and disturbances in social-familial support systems affect the cycling of the disorder against the backdrop of genetic, biological and cognitive vulnerabilities. Current models of psychosocial treatment focus on modifying the effects of social or familial risk factors as an avenue for improving the course of the disorder.     

Risk factors for family violence: introduction to the special series

The purpose of this series is to review the strength of risk and protective factors for each of seven forms of family violence: partner physical, psychological, and sexual abuse; child physical, psychological, and sexual abuse and child neglect. Definitions of risk and protective factors are presented, as is the five-stage prevention intervention research cycle. The reviews in this series are designed to provide stakeholders with a convenient summary from which to identify the strengths and weaknesses of the current risk and protective factor knowledge. Such reviews are necessary to allow for the eventual construction of etiological models that can support the development of preventive intervention programs and research into their efficacy.     

Personality disorder and violence: understand violence risk: an introduction to the special section personality disorder and violence

This paper introduces the Special Section on personality disorder and violence. The first paper evaluates the impact of removing the Psychopathy Checklist (PCL-R) as a mandatory element of a major approach to the assessment of violence risk-the HCR-20. The second paper considers violence to self as well as violence to others; it examines the influence of dysfunctional personality traits in a sample of female offenders. The third paper provides a systematic framework for risk formulation, discussing how to bridge the gap between nomothetic research and the individual case. This paper concludes by arguing that there is a need to shift perspective from asking "what?" dysfunctional traits are relevant to future violence to "why?" are particular traits relevant. The "why?" question is particularly germane in the forensic arena where expert testimony must endeavor to provide a causal explanation of risk processes at the level of the individual.     

Causal inference in lead research: introduction to the special section on the neurobehavioral effects of environmental lead.

This Special Section on the Neurobehavioral Effects of Environmental Lead includes empirical reports from three major longitudinal prospective studies and a review of animal research modeling effects of lead on human cognition. This Introductory article addresses a fundamental controversy in lead and other epidemiologic research. It is argued that, contrary to conventional wisdom, valid causal inferences can be made from correlational research. Justification for this is to be found in contemporary frameworks drawn from the field of the philosophy of science; an essential, but often neglected perspective for such metatheoretical issues as causal inference. It is concluded that the nonexperimental methods described in the articles comprising this Special Section can, indeed, contribute to causal formulations of lead effects on human development, and that such inferences are not exclusive to experimental evidence.     

Building an evidence base for DSM-5 conceptualizations of oppositional defiant disorder and conduct disorder: introduction to the special section

The DSM-5 ADHD and Disruptive Behavior Disorders Work Group recently outlined a research agenda designed to support possible revisions to the diagnostic criteria for oppositional defiant disorder (ODD) and conduct disorder (CD). Some of the areas in need of further investigation include (a) examining the clinical utility of the current diagnostic system in girls, (b) further clarifying the developmental progression from ODD to CD, (c) determining whether facets of ODD symptoms can help explain heterotypic continuity and enhance predictive validity, (d) evaluating the clinical utility of a new subtyping scheme for CD on the basis of the presence of callous-unemotional traits, and (e) comparing the clinical utility of dimensional versus categorical conceptualizations of ODD and CD. This special section was organized in an attempt to provide data on these issues using a diverse array of longitudinal data sets consisting of both epidemiological and clinic-based samples that collectively cover a large developmental span ranging from childhood through early adulthood.     

Personality and politics: introduction to the special issue

This special issue of Journal of Personality brings together 10 original articles addressing the intersection of personality and politics. Articles build on classic traditions in political psychology by presenting both idiographic and nomothetic work on the motivational, cognitive, ideological, attitudinal, and identity correlates of many different aspects of political behavior. This work is used to understand political activism and leadership as well as everyday political behavior. We hope this collection of articles will inspire our readers to explore new investigations in personality and political psychology.
