Could you be a Hidden Aspie?
If you feel that you may be a Hidden Aspie, especially after reading about the normal Aspie traits and difficulties, you can take Simon Baron Cohen's test online. Remember though that the online test is designed for adults, and should not be taken as a substitute for a professional evaluation.
There are two versions available. The shorter test involves answering 50 questions as honestly as possible. NeuroTypical (NT) people scored 16.4 while 80% of people diagnosed with autistic spectrum disorder scored 32 or over.
The second more involved test consists of 150 questions and provides 2 scores and an assessment. The scores measure you against both the Aspie and NT scales, with a conclusion as to which you are more inclined. The benefit of this test is that it also provides you with a graph mapping out your strengths and weaknesses in various social areas, and provides you with a PDF which contains your scores, the graph, and detailed breakdowns of each area and how you are in respect of them.
The best way to know for sure, however, is to ask your GP for a diagnostic test. The National Autistic Society (NAS) can provide advice and an information pack to give to your GP.
The Autism Research Centre (ARC) provide a number of research tests to download provided that they are used for genuine research purposes, and provided due acknowledgement of ARC as the source is given. The ARC tests are posted to enable free access to academic researchers. None of them are diagnostic
