It isn't a black box test, it's the World Health Organization's ADHD self-reported screening scale for the DSM-V [1]. They clearly gathered a research group to include roughly 50/50 positive and negative participants: this isn't a random sample of the population that happens to be 50% positive on a self-reported ADHD scale.
Obviously using the self-report test is nowhere near is useful as getting people with a formal diagnosis, but finding 250 study participants with formal ADHD diagnosis (and verifying each case) is waaaaay more expensive. Trials like this sometimes pave the way for a more expensive and exhaustive study to be funded.. and then people come into these threads to complain "great another study telling us what we already knew."
