ACORN Outcome Questionnaires Manual


ACORN questionnaires are unlike any other outcomes questionnaires. ACORN questionnaires are designed to be dynamic: flexible and easily modified to suit the needs of each organization. Unlike traditional static questionnaires, which consist of a fixed number of specific items and a particular sequence, ACORN questionnaires are constructed from a pool of available items with understood psychometric properties. For more discussion on questionnaire development, see the topic Outcomes Measurement 2.0

Each specific version of a questionnaire may contain a slightly different mix of items in different orders. However, since the properties of each item is known and all of the questionnaires share at least 8-10 items in common, it is possible to equate scores from different questionnaires.

This sophisticated approach to measurement is made possible by the use of the data analytic capabilities of software products from the SAS Institute.

The price for the ACORN Clinician's Decision Support Toolkit can be found at These charges cover the cost of forms, data entry, maintenance of the data warehouse, and the ongoing research and development activities in support of the collaborative community of ACORN questionnaire users.

The ACORN Toolkit data warehouse is one of the largest databases on mental health outcomes in the world, with data for over one million adults, adolescents and children collected using a variety of questionnaires. The ACORN Toolkit Summary Results Viewer displays summary outcome data and graphs from various ACORN questionnaires based on all data in the data warehouse (unless an organization requests that its data not be included in the summary results). The viewer provides the user with tools to break down results by questionnaire type, diagnoses and payer plan type.
