SF-86 doesn’t ask any questions like this. They’ll send out agents to collect more in-depth questions that may probe situations like this. They’ll also ask friends, neighbors, family etc about all sorts of things. This isn’t really the kind of question a self-reported form can answer (except for the most obvious questions like debt problems). It takes a human who can synthesize various statements to get pictures like “this person could be blackmailed” or “this person can’t keep a secret.”
