Primary Outcome Measures

Name	Time	Method
The screening-instrument RAADS-R (self-report) preferably seperates between individuals with high-functioning ASD and individuals without ASD, that is the RAADS-R has better sensitivity and secificity than previous screening-instruments, e.g. AQ (Autism Questionnaire) and EQ (Cambridge Behaviour Scale). Primary targets: total sum and dimension sum for calculating the cut-offs between individuals with ASD and individuals with axis-I disorder but without ASD.

Secondary Outcome Measures

Name	Time	Method
The screening-instrument RAADS-R preferably seperates between individuals with high-functioning ASD and individuals with primary axis-I disorders than previous screening-instruments like AG (Autism Questionnaire) and EQ (Cambridge Behaviour Scale). Secondary targets: total sum and dimension sum for calculating the cut-offs between individuals with ASD and individuals with axis-I disorder but without ASD.
