**Note: This is a relatively new TestMyBrain test with limited normative data; it has not been validated to the same extent as our other tests. The EMA versions are being used in ongoing studies, but their data have not yet been published. Therefore, we currently recommend using this test only if a norms-based interpretation is not required.
