The ComFor-2 Forerunners in communication can be used to test which kind of interventions are suitable to improve communication for people with autism. It addresses two core questions: First, what is the most suitable form of augmented communication; And second, at which level can the means chosen be offered.

Suitable for

Children and adults with (psychomotor) developmental levels of 12 to 60 months; the ComFor-2 was primarily developed for people with autism spectrum disorder, with little or no verbal communication

Language Versions

English, Dutch, Danish, French, Italian, Spanish, and Swedish

Product Description

The ComFor-2 is a revised version of the broadly used ComFor. The test design and application are unchanged, but the test materials have been thoroughly reviewed and modernised. The new test kit can be used in combination with previously published manual and forms.

Please note that the testkit includes stimulus materials only - the manual, scoring forms and word cards are also required to be able to administer the assessment.

The test consists of a range of sorting tasks. Clients are required to sort objects, photographs, pictures and words according to both their literally perceptible features ("presentation"), and their meaning ("representation").

The score on these tasks gives a clear indication of the level on which augmented communication should be offered. For example, does a picture of a cup only mean "cup", or can it be used to indicate an activity: "drinking".

More research with the ComFor has been published in a number of international journals. A small selection of recent and interesting articles:

There are no norms for the ComFor-2, since it is developed to obtain an indication of suitable communicative interventions. The instrument is not meant for diagnosis. The manual contains extensive information on interpretation and applications.
