PURPOSE:  The purpose of this article is the presentation of a multidimensional guideline for the diagnosis of anxiety and anxiety-related behavior problems in people with intellectual disability (ID), with a substantial role for the nurse in this diagnostic process.

DESIGN AND METHODS:  The guideline is illustrated by a case report of a woman with ID with severe problems.

FINDINGS:  It appears that a multidimensional diagnostic approach involving multidisciplinary team efforts can result in a more accurate diagnosis and improved subsequent treatment.

PRACTICE IMPLICATIONS:  Nurses should be engaged in the diagnostic process because of their ability to make direct observations and to actively participate in carrying out all parts of the guideline.
