RECRUITMENT
Parents were invited to participate via phone call from the study team. Navigators were invited to participate via email solicitation. Parents and navigators were each compensated for their time with a $50 gift card. Informed consent was obtained from all parents included in the larger trial and parents were given the option to opt out of the interview. Informed consent was obtained from navigators upon recruitment to the current study. All procedures were in accordance with ethical standards of the institution [masked for review].All parent interviews and 6 of the 7 navigator interviews were completed by phone and audio recorded by one of three of the authors who were trained in qualitative interviewing (JL, PF, and SBF). The final navigator interview was completed and recorded in person. Interviews were completed after families reached diagnostic ascertainment. Time between termination of FN and parent interview ranged from 4 months to 3 years, with the majority of interviews conducted within the first six months after intervention completion (20 of 21 were conducted within 6-months). One interview was delayed due to initial difficulty reaching the family. All recordings were professionally transcribed, and the four interviews conducted in Spanish were also professionally translated. Transcripts were checked for accuracy by bilingual study staff (JL, PF, and AC). Recordings ranged in duration from 28 to 51 min. Bilingual members of the study team reviewed all transcriptions and translations for errors. Transcripts were analyzed in English.
