Hoarding involves the acquisition of and inability to discard large numbers of possessions that clutter the living area of the person collecting them. It becomes a disorder when the behavior causes significant distress or interferes with functioning. Hoarding can interfere with activities of daily living (such as being able to sit in chairs or sleep in a bed), work efficiency, family relationships, as well as health and safety. Hoarding behavior can range from mild to life-threatening. Epidemiological findings suggest that hoarding occurs in 2-6% of the adult population, making it two to three times more common than obsessive-compulsive disorder. The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) now includes Hoarding Disorder as a distinct disorder within the OCD and Related Anxiety Disorders section, creating a demand for information about it. The Oxford Handbook of Hoarding and Acquiring is the first volume to detail the empirical research on hoarding. Including contributions from all of the leading researchers in the field, this comprehensive volume is divided into four sections in addition to introductory and concluding chapters by the editors: Phenomenology, Epidemiology, and Diagnosis; Etiology; Assessment and Intervention; and Hoarding in Special Populations. The summaries of research and clinical interventions contained here clarify the emotional and behavioral features, diagnostic challenges, and nature of the treatment interventions for this new disorder. This handbook will be a critical resource for both practitioners and researchers, including psychiatrists, psychologists, neurologists, epidemiologists, social workers, occupational therapists, and other health and mental health professionals who encounter clients with hoarding problems in their practice and research.

Obsessive compulsive disorder (OCD) has perplexed clinicians and researchers for many years. Despite recent advances in our understanding of and ability to treat this debilitating problem, many people with OCD do not benefit or benefit only marginally from existing treatments. Newer approaches and a better understanding of the pathogenesis of OCD are needed. One such approach that has shown considerable promise in recent years is cognitive therapy. Recent studies have found cognitive therapy to be an effective treatment for OCD, and research on cognitive theory for OCD is rapidly expanding. This volume assembles nearly all of the major investigators responsible for the development of cognitive therapy (and theory) for OCD, as well as other major researchers in the field to write about cognitive phenomenology, assessment, treatment, and theory related to OCD. Each chapter of the book is written by an expert in the area. The first section of the book describes the domains of cognition in OCD and the subsequent section outlines measurement strategies where the efforts of an international working group of scholars to develop measures of OCD cognition are described. Reviews of OCD cognitions in OCD spectrum disorders and in specific populations (for example, the elderly and children) are reviewed in following sections. Finally, the role of these cognitions and cognitive processes in treatment is described.

The relationship people have with their possessions ranges from purely utilitarian to intensely emotional. For most people, their personal possessions provide them with a sense of security, comfort, and pleasure. However, if someone loses the ability to distinguish useful or important possessions from those that make life overly complicated, the objects can become a prison. For people who suffer from Hoarding Disorder (HD), the process of getting rid of unneeded objects is not easy. For them, possessions never "feel" unneeded and trying to get rid of them is an excruciating emotional ordeal. This Second Edition of Treatment for Hoarding Disorder is the culmination of more than 20 years of research on understanding hoarding and building an effective intervention to address its myriad components. Thoroughly updated and reflective of changes made to the Fifth Edition of the Diagnostic and Statistical Manual for Mental Disorders (DSM-5), this second edition of the client Workbook and accompanying Therapist Guide outlines an empirically supported and effective CBT program for treating hoarding disorder. This Workbook is meant to guide clients through their treatment for hoarding disorder with their clinician. It includes homework, forms, exercises, and behavioral experiments for clients to test their personal beliefs about possessions, develop an organization plan and filing system, and sort and organize items room by room. A major goal of the treatment is to recapture the positive role of possessions in the lives of people with hoarding problems, and strategies are outlined for sustaining gains and making further progress, as well as for managing stressful life events that can provoke problematic acquiring and difficulty discarding.

Accounts of hoarding behaviors have appeared in literature, as far back as 319 B.C.E. in the writings of Aristotle's student Theophrastus; in the news, like New York's infamous Collyer brothers in the 1940s; and more recently in popular reality television series. But it wasn't until the publication of DSM-5 in 2013 that hoarding was classified as a disorder in its own right rather than as a symptom of obsessive-compulsive disorder or obsessive-compulsive personality disorder. In this single source, readers can access the most up-to-date comprehensive information on what is known about the disorder. Drawing on the authors' own clinical experiences as well as the latest published research, Hoarding Disorder: A Comprehensive Clinical Guide examines key features of the disorder and treatment approaches, such as: * Phenomenology, including diagnosis, comorbidities, and assessment* Etiology, from both a cognitive-behavioral and a neurobiological perspective* Psychotherapeutic and pharmacological treatments, from cognitive-behavioral therapy, harm reduction strategies, and community approaches to the efficacy of specific drugs* Challenges, including working with elderly patients, managing cases of animal hoarding, and distinguishing and addressing squalor Key points for each chapter and numerous case studies will help readers easily reference and retain information, and the appendices feature useful symptom rating scales that can be applied to practice. For psychiatrists, psychologists, human service and other mental health professionals, peer support counselors, community advocates, and professionals in training, this invaluable book will improve the reader's knowledge and skill in treating patients with hoarding disorder, both those with straightforward presentations and those with complicated ones.

This Therapist Guide is written for mental health clinicians-psychologists, social workers, psychiatrists, counsellors, and psychiatric nurses-to guide effective treatment of people with hoarding disorder. It provides numerous assessment and intervention forms to help clients use the methods described in the intervention. A major goal of the treatment is to recapture the positive role of possessions in the lives of people with hoarding problems, and strategies are outlined for sustaining gains and making further progress, as well as for managing stressful life events that can provoke problematic acquiring and difficulty discarding.
