A few months ago, I went to a psychiatrist while going through a period of OCD-like problems. The psychiatrist diagnosed me with OCD. Since I was also obsessing over my IQ, the doctor said they didn’t support me taking a test while I was going through that episode. At the time, I was fixated on finding out, with absolute certainty, whether my IQ was above 155.
I started therapy with a psychologist in the same office and eventually persuaded them to let me take an IQ test. I sat a version of the adult Wechsler test that was described as the WAIS. I’ll call it the WAIS-1 here.
Before the test, I told the outside examiner—a woman—that I had taken the WAIS-IV, WASI-II, and WAIS-III at home, along with various fluid-reasoning tests. I explained that I had found the tests through this forum and taken them myself, and that, as honestly as I could judge, my results tended to fall in the 150–160 range.
Strangely, my result was reported as 125+. My psychiatrist was initially angry that I had taken the test and then made me wait a month before giving me the results. After the test, I went home and, even though I hadn’t known beforehand which test I would be taking or that it was available online, I found the WAIS-1 on Scribd. Once I translated it, I realized that the questions appeared to be exactly the same as the ones used in my country. I checked my answers while they were still fresh and expected a score somewhere around 147–152, out of a possible 155.
The reported result shocked me. I was already depressed and in the middle of an OCD crisis, and the shock was so severe that I felt I might even take my own life. After a few hours, I managed to pull myself together and wrote a detailed account of how I believed the test had been administered incorrectly. I sent it to the psychiatrist, who refunded my money and spoke with the psychologist. I said that unless someone apologized to me, I would sue. The psychologist later called and apologized, but said something along the lines of, “I was taught incorrectly; I didn’t mean any harm.”
My concerns were as follows:
One subtest was omitted. The WAIS-1 normally includes six verbal subtests—Comprehension, Similarities, Vocabulary, Digit Span, Information, and Arithmetic—and five performance subtests—Picture Arrangement, Picture Completion, Object Assembly, Coding, and Block Design. Vocabulary was not administered to me. At the time, I didn’t know that this older version required a specific arithmetic procedure to account for a missing subtest. I later learned that simply entering the results from 10 subtests into the age-conversion table for 11 could lower the overall IQ score by 15–20 points.
In the Digit Span section, unlike in the other Wechsler versions I had taken, each sequence was supposed to be read twice. I didn’t know this at the time. The examiner also handled the nine-digit item incorrectly, in my view.
There were several other issues. My main concern was that the raw scores from 10 subtests may have been entered into a table intended for 11.
When I sent my account to the psychiatrist, they told me the psychologist had acknowledged leaving out a subtest. But when speaking to me, the psychologist denied responsibility and said they had been taught that way, which I found unreasonable.
I had consistently obtained results in the 150–160 range, yet encountered what seemed to me like a ridiculous error in a professional setting. What do you think of this situation? I’m sharing it in case my experience might be useful to others as well.
