Intellectual Disability: Definition, Diagnosis, Classification, and Systems of Supports, 12th  Edition  

The AAIDD Manual leads the field in understanding, diagnosing, and classifying the construct of intellectual disability (ID). The 12th edition integrates the findings and developments of the last 10 years and presents the operational definition in a systematic approach to diagnosis, optional subgroup classification, and planning of systems of supports for people with ID. In addition, the 12th edition examines the construct of age of onset in light of the developments of the last 10 years and changes that criterion in a way that will be critically important for professionals in the field. The material in the 12th edition is presented in a user-friendly fashion and includes advance organizers for each chapter to facilitate easy access and understanding.

The Diagnostic Adaptive Behavior Scale® (DABS®) User's Manual provides essential preparation for using the DABS.

Adaptive behavior consists of conceptual, social, and practical adaptive skills.

Designed for use with children between the ages of 4 - 21, the norm-referenced DABS interview provides a precise assessment of adaptive behavior for the purpose of determining whether the person meets one of the criteria necessary for a diagnosis of intellectual disability (ID). 

The DABS has a number of unique features that support its precision, accuracy, validity, and credibility in making a diagnosis of ID. The DABS:

• Measures some aspects of adaptive behavior that are not currently measured by other standardized instruments, including naiveté, gullibility, and technology-based skills.
• Uses item response theory (IRT) to reliably measure individual performance levels across the continuum of adaptive skills and ages.
• Provides precise information to assist users in determining significant limitations in adaptive behavior.

The User’s Manual includes a sample copy of the interview form. Bundle packs of interview forms are also available in the bookstore.

The Diagnostic Adaptive Behavior Scale ® (DABS®) is an instrument for assessing the adaptive behavior of people between the ages of 4 and 21 for the purpose of determining whether the person meets the second criterion for a diagnosis of intellectual disability (ID). The second criterion is a significant limitation in adaptive behavior as expressed in conceptual, social, and practical adaptive skills. The DABS is a norm-referenced instrument that uses data obtained from an interview with a respondent who knows the person very well.

The DABS has a number of unique features that support its precision, accuracy, validity, and credibility in making a diagnosis of ID, including:

• Measures some aspects of adaptive behavior that are not currently measured by other standardized instruments, including naiveté, gullibility, and technology-based skills.
• Designed using item response theory (IRT) and reliably measure individual performance levels across the continuum of adaptive skills and ages.
• Provides precise information to assist users in determining significant limitations in adaptive behavior.

The book addresses the complex and evolving concepts of "community," including living arrangements, work, other daytime activities, financial resources, relationships, personal interests, health and well-being, faith, opportunities for learning and personal growth, self-determination and informed decision making, and rights and responsibilities as a citizen. 

Specific topics include using person-centered and positive support practices, housing, employment, social inclusion and relationships, self-determination and self-advocacy, supported decision making, health and wellness, planning for healthy and engaged aging, practices that promote quality outcomes, and the direct support workforce.

Each chapter includes advance organizers, discussion questions, and a resource list. The book is ideal as an ancillary textbook at the undergraduate or graduate levels and as a staff development tool.
