We were offered Healios for DD12 but were a bit ambivalent because we thought a lot of nuance in how she presents could be lost in an online assessment. We also spoke with the NHS clinician who initially referred her for an ASD assessment and they agreed that an in-person assessment might be better, even though it meant a much longer wait.
A few months later we were offered Healios for DS11. In that instance, a different NHS clinician said they had used Healios for their own child's assessment and though it was good. She said if our child didn't engage well online with Healios, then we could let her know and we wouldn't lose our place for the in-person assessment. So we felt there was little to lose.
In the end, we're happy with we went with Healios and are considering whether we should go back and request it for DD.
We had a 2-day assessment. The first session was about a 20-30 min intro to the process and gathering some general info, followed by 1 hour with me to outline our concerns and discuss some developmental history. The clinician then had about 1 hour with DS and a then a short follow-up with me.
The second session was only with me and DP with a different clinician over about 2-2.5 hours, talking in depth about DS's history.
We got the report (and a diagnosis) about a week later. After reading the initial report, I requested a few small changes and they were made and the final report delivered to me within 24 hours.
We'll be having a feedback/follow-up call next week to ask any questions, and then DS is having an ADHD assessment with them in the new year.
Overall, a very positive experience.
