Background:
An evaluation of the most commonly used ROM measures in Dutch psychiatry is lacking, both for severe mental illnesses and for common psychiatric disorders.
Aim:
To provide an overview of the characteristics and quality of outcome measures.
Method:
A literature study yielded six outcome measures. The psychometrical, clinical and practical aspects of these scales are described.
Results:
The measures are suitable and are of adequate quality.
Discussion:
It remains to be seen if any of the outcome measures are suitable for both serious and less serious mental illnesses. The use of a combination of a self-rating scale and an observerrating scale that measure symptoms and domains of functioning may be the most promising choice.
