Participants
Parents or legal guardians were eligible for this qualitative study if: (1) they were randomized to and received FN; (2) they spoke English or Spanish; and (3) their child received a diagnosis of ASD after their formal diagnostic evaluation. Parents were purposively sampled from the larger sample of parents participating in the RCT. All family navigators who worked with at least one family as part of the larger RCT were eligible for the navigator interviews. Parents were selected based on navigator nomination of parents who might be most interested in a post-trial follow-up interview. We asked navigators to recommend families who they felt had a variety of experiences with FN (both positive and negative; (participant IDs follow quotes). Although we used this strategy in an attempt to garner a variety of opinions, we recognize this may be a source of bias in our population, as FNs may have preferentially recommended individuals who they thought would report a positive experience.As shown in Table Participant characteristics
