The HDI identifies psychological or psychiatric symptoms in order to highlight areas that require further attention. It is often administered prior to or at the first meeting with an individual. During treatment, the HDI can be re-adminisitered to monitor symptom change and document progress. At termination, it can be used to document outcomes.

How to Use the Assessment
The HDI consists of a self-report form (HDI–Self), a parent form (HDI–Parent), and a Background Information Questionnaire. The Background Information questionnaire systematically collects important demographic information and medical/mental health history. All components are available in handscored and software format. With the software format, you can instantly generate Interpretive Reports or Health Summary Reports.
