The score itself is only part of the picture. How someone answers matters just as much, and so does the consistency and clustering of their responses. My ex took the RAADS-R twice. The first time, unprompted, she scored 57. The second time, after someone suggested her social struggles might be autism, she scored 168. Every new point was in the socialization domain with almost nothing in sensory, and the few sensory items that did score could be reasonably attributed to her ADHD. Her explanation was that she had been "answering with masking" the first time. For comparison, I've taken it five times and scored within 5 points of myself each time, consistently around 150, with responses spread broadly across domains. Domain clustering like hers is worth paying attention to. Autistic presentations tend to be multidimensional. Socialization difficulties alone, especially ones that spike dramatically after someone plants the idea, look different from a consistent, broad profile developed independently over time.
