Does a 3Di assessment accurately capture my child's autism

I'm interested to know whether parents who have experienced a 3Di parent interview as part of their childs ASD assessment feel that it has accurately captured and/or influenced the outcome of a diagnosis. I'm aware that the 3Di can be done as a "brief" assessment or a more comprehensive one depending on what is required, but I worry about the validity of a brief 3Di assessment to accurately inform the overall assessment process.

Are there any parents who have specific views about their own parent interview experience?
