Hi, Berrylotus, and welcome to Psych Central! Not to worry, this "test" doesn't take the place of official evaluation by a professional. The 15 on schizophrenia is non-significant. I am not sure that the sub-scores go to 100 and can be evaluated as percentages. So, a 90 is not 90%.

Feel free to read the sitckies at the top of this forum to give you more details about what the scores mean. Actually, your overall score is on the low side, but that's good. Nonetheless, it doesn't mean that you aren't hurting and having struggles. Okay?
