Background

Significant racial, ethnic, and socioeconomic disparities exist in access to diagnostic evaluations and behavioral interventions for children with autism spectrum disorder (ASD). The most recent Centers for Disease Control and Prevention (CDC) data report found that in the United States Black children with ASD were less likely than White children to have a diagnostic evaluation by age 36 months, suggesting that Black children experience delays in ASD diagnosis and therefore delayed access to ASD-specific services [1]. The prevalence of ASD was also found to be lower in Hispanic children, compared to non-Hispanic children [1], suggesting that Hispanic children are identified less frequently than White or Black non-Hispanic children, and thus may be unable to access or benefit from evidence-based ASD services. Hispanic children with ASD, in particular, have been found to have difficulty accessing services because of language barriers, higher odds of not having a personal doctor, and increased difficulty receiving referrals compared with non-Hispanic, White children [2]. Additional research has shown a lower prevalence of ASD in children with lower socio-economic status (SES) compared to children with higher SES [3]. Although screening for developmental delays has increased in recent years [4] and overall ASD prevalence in the United States has increased to 1 in 44 children [1], it is clear that differential identification is affecting equitable access to services.

Targeted interventions are needed to reduce health disparities and improve long-term outcomes in obtaining access to diagnostic and treatment services for low-income, and racially and ethnically underserved children. Family Navigation (FN) is one such intervention. Emerging from principles of patient navigation for patients with chronic diseases [5,6,7], FN is designed to reduce health disparities by providing families with individually tailored support and care coordination [8]. FN for ASD is an evidence-based intervention [8,9,10,11,12] with 11 core components (e.g., training, fidelity monitoring, linguistic and cultural brokering, emotional support, care coordination, etc.) [8].

The current study was part of the implementation evaluation of a randomized clinical trial (RCT) of FN for improving access to diagnostic services and treatment for young children referred for an ASD evaluation to their health system’s Developmental and Behavioral Pediatrics Clinic [12]. FN is an intervention grounded in the chronic care model in which a navigator works closely with the family unit to support access to a specific care service over a defined period of time. FN falls under the umbrella of community or lay health worker interventions [13]. In this larger study, families in the intervention group (i.e., received the FN intervention) worked with a navigator from the time of identified concern and referral for ASD assessment to 100 days after diagnostic ascertainment. While results indicated significant reductions in time to diagnostic evaluation for all families who were randomized to FN, Hispanic families receiving FN particularly benefitted compared to Hispanic families (hazard ratio 2.81 for Hispanic children reaching diagnostic resolution with FN compared to non-Hispanic children who received FN) who did not receive the intervention (citation removed for masked review). At the same time, families who received FN in Massachusetts and Connecticut had a significant reduction in time to diagnosis; families who received FN in Pennsylvania did not. These findings indicate that FN is effective, but only in certain settings, and differentially based on the population served.

As evidence-based practices (EBPs) such as FN are disseminated and scaled-up, modifications to increase fit to specific populations or contexts are frequently made – both as adaptations, which are purposeful and planned, and as unplanned changes that occur naturally in response to challenges during implementation [14, 15]. Research has shown that adaptations to increase fit to local contexts and cultures, especially for racially and ethnically diverse populations, can improve engagement, acceptability, and clinical outcomes [15,16,17,18]. For example, a recent study comparing two pilot trials of FN found improvements in study recruitment, patient satisfaction with care, and completion of diagnostic assessment in the second pilot after implementation of a number of adaptations, including lengthening the follow-up period and changing the referral site [10]. However, to our knowledge no other studies have examined adaptations in larger scale randomized trials of FN. As FN interventions for children with ASD become more widespread, an adaptive approach to program design and implementation is crucial to ensure best practices and equitable benefits for families [19].

To best adapt FN to maximize effectiveness for low-income, racially and ethnically underserved families with children with ASD, stakeholder perspectives must continue to be taken into consideration [20]. Therefore, the aim of this study was to document patient and FN opinions about FN, and understand adaptations that may be needed to improve future implementation. To our knowledge, this is the first paper to analyze patient and navigator opinions about FN, along with considerations for improvement. Although FN is designed to improve access to care for the family unit, it was not initially designed with rigorous stakeholder input. Thus, these findings hold value to the field to refine the intervention with a more user-centered approach.

Methods

Study rational and framework

This study was approved by the Boston University Medical Campus and Boston Medical Center Institutional Review Board. Using an iterative qualitative design, the current study aimed to capture the voices and experiences of parents of children with ASD who received FN during their diagnostic journey, as well as the perspectives of navigators who worked with families. Interview guides and analysis of the qualitative data (key informant interviews) were developed from the Framework for Reporting Adaptations and Modifications-Expanded (FRAME) [15]. The work presented represents an advancement of this implementation science framework by extending beyond the provider perspective to also include the consumer voice [21]. In addition, we draw upon recommendations for designing implementation studies through a health equity lens to understand different patient characteristics and structural factors that impact equitable implementation [19]. Drawing from the experiences of parents of children with ASD and family navigators, the current study aimed to answer the following question: How should FN be adapted for dissemination and to ensure equity in both access to FN and ASD diagnosis and treatment across underserved populations?

Context

The current study was part of an implementation evaluation of a RCT that took place in 11 urban primary care sites in 3 cities. Sites are described in detail in our previous publication [citation removed for masked review]. In short, primary care and developmental pediatrics clinics were all affiliated with academic medical centers in their geographic region. Although demographics varied by city, all sites served culturally and linguistically diverse, predominantly low-income populations. In the larger study from which participants from the current study were drawn, 339 parents or legal guardians with children between the ages of 15 and 27 months who were determined to be “at-risk” for ASD through screening in standard primary pediatric care were randomized to receive either a FN intervention or conventional care management control. Family navigators received training in topics such as ASD management, community resources, and motivational interviewing. Navigators met with families for a minimum of three standardized visits at critical timepoints in the diagnostic process. Beyond these visits, the intervention allowed for flexibility and tailoring to family preferences and needs. Families worked with the navigator or care manager until 100 days after receipt of a formal diagnostic evaluation. This study was approved by the hospital-based institutional review board. This paper follows the COREQ guidelines for qualitative research.

Data collection

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.

Qualitative approach and analysis

Grounded in methods common in implementation science, the qualitative approach utilized in this study was targeted and practical, and designed for rapid dissemination of findings [22]. Semi-structured qualitative interview guides (Appendix 2) for parents and navigators were developed using components from FRAME, an implementation framework used to characterize modifications to interventions [15]. Interview guides were designed to assess changes or adaptations to the intervention that parents or navigators implemented, witnessed, or reported a desire to see. For example, the following question was included in both the parent and navigator interview guide: “If you could change anything about family navigation, what would you change?” Following the lead of the parent or navigator, interviewers were guided to ask probes to specify who the modification should be for, what exactly should be changed, and the reason for the change. Interviews were conducted until data saturation was reached.

FRAME was also used to create transcript summary templates that would enable a rapid analytic approach focused on specific actionable findings [22,23,24,25,26]. We used an iterative design, which means we were continually updating our interview questions as we collected data in order to refine our data collection tools and select our framework. Based on this method, we selected FRAME [15] and thus recommendations were organized and assessed using FRAME. Rapid qualitative analysis is a streamlined approach to qualitative analysis designed to be less resource intensive than traditional qualitative analysis, thus requiring a shorter timeframe. In this study, two of the authors (JL and PF) independently coded all transcripts using the transcript summary templates. Any conflicts were discussed with a senior member of the team (SBF) until consensus was reached. In line with rapid analysis methods, matrix analysis was used to organize and assess recommendations in Microsoft Excel [22, 27]. This strategy allowed for a logical representation of the data that was consistent with our structured approach to analysis anchored to the FRAME [15]. All recommendations made by parents or navigators were included in analysis, including both recommendations for adaptation to the intervention (henceforth referred to as “true adaptations”), and recommendations that reflected existing components of the intervention. Results are below, and expanded in Appendix 1.

Results

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 1, 21 parents and 7 family navigators were interviewed. This included 8% of parent participants, and 100% of navigators included in the larger study. All parents and navigators provided verbal consent to participate in the interviews. Demographics of parents and navigators were similar to those of the larger study. Thirty-eight percent (n = 8) of parents were Hispanic, 48% (n = 10) were non-Hispanic, Black, and 14% (n = 3) were non-Hispanic, White. Forty-three percent (n = 9) were born outside of the United States. Eighty-one percent (n = 17) opted to be interviewed in English and 19% (n = 4) chose to be interviewed in Spanish. Eighty-six percent (n = 18) of parents were high school graduates and 90% (n = 19) were enrolled in public insurance. Mean parent age at the time of the interview was 35.8 years (SD = 6.8) and mean child age at interview was 4.2 years (SD = 1.5). Sixty-two percent (n = 13) of children were male. Matching the larger study population in which 90% of participating parents were mothers, 20 (95%) of the parents interviewed were biological mothers; 1 parent was a biological father. All 7 navigators interviewed were female, as all navigators in the larger study were female. Twenty-nine percent (n = 2) of navigators were bilingual (1 English/Spanish, 1 English/Haitian Creole). Twenty percent (n = 2) were Hispanic, 29% (n = 2) were non-Hispanic Black, and 43% (n = 3) were non-Hispanic White. Seventy-one percent (n = 5) of navigators had bachelor’s degrees and 29% (n = 2) had master’s degrees.

Table 1 Participant characteristics

Themes

The majority of parents and navigators mentioned benefits of FN. Multiple parents cited feeling more confident and emotionally supported as a result of working with their navigator, and that they felt the navigator made the process of moving from concern for ASD to engagement in services easier than it might have been otherwise. Nonetheless, 38 recommendations for adaptations to FN emerged. Of these recommendations, 29 represented adaptations to the intervention itself and the remaining nine recommendations reflected challenges in (1) training/supervision of navigators, (2) hiring navigators, and (3) integration of the intervention into the healthcare system. Twelve recommendations were unique to parents, 15 were unique to navigators, and 11 overlapped between the groups.

Using FRAME, recommendations were assessed for what should be modified, the level of delivery at which modifications should be made, consistency or inconsistency with fidelity to the intervention, and the goal for modification (Table 2) [15]. Recommendations for adaptations to content were most commonly suggested (47%, n = 18), followed by those to context (26%, n = 10), implementation and scale-up (16%, n = 6), and training and evaluation (11%, n = 4).

Table 2 Suggested adaptations organized by FRAME domains [15]

Content adaptations

As guided by domains of FRAME [15], content recommendations addressed changes or additions to key components of the intervention. The nature of these recommendations fell into the FRAME categories of adding elements, tailoring/tweaking/refining, spreading (breaking up session content over multiple sessions), changes in packaging or materials, and lengthening/extending (pacing/timing).

Parents and navigators suggested adding new navigator responsibilities. For example, six parents suggested that navigators could either connect parents to more in-depth educational resources about ASD and parenting children with ASD or offer this education themselves. One parent said, “Just like when you have a newborn, I think [navigators] should have some type of classes for how to deal with kids that have autism” (4). Parents and navigators also suggested adding more active navigator follow-up with parents. For example, they suggested that navigators educate parents on how to access services and navigate the system on their own; meet with the developmental behavioral pediatrician (DBP) prior to the diagnostic visit to enable the navigator to better prepare the family; connect parents to other parents of children with ASD; coordinate/consolidate services for families involved in multiple programs; attend all DBP visits with families; and connect parents to mental health therapists as needed. Parents suggested that navigators tailor the communication type and amount of communication to meet specific parent preference: “A navigator needs to know their family and if the family wants them to be just showing up randomly or calling and trying to show them new things unasked, then that’s good. But if they don’t, and they want to go day-to-day if they need something then they can call… knowing the family that they’re working with and knowing what that family prefers, how that family prefers to work with them” (3).

Parents also made recommendations to refine the intervention. A parent of five children suggested that navigators offer support for siblings of children with ASD: “Maybe a little bit more on how to better explain things to [my other children], ‘cause they kind of get it. I have a 6-year-old actually who just really is trying to understand” (7). Parents also suggested that navigators should work to de-stigmatize ASD: “That additional person there to help you out through the process just makes you more comfortable with the actual diagnosis and, you know, accepting that there is nothing different, I guess, with your child and the diagnosis” (20).

Parents and navigators recommended spreading the FN intervention across a longer period of time than specified in the larger RCT to allow for FN at challenging transition points, such as when children age out of early intervention (EI) services (usually at age 3) and must initiate services elsewhere. One parent said, “If my time was split between her getting diagnosed and going into [EI] and then doing that transition again at the end of 2-year-old to three – say a month or two before that, and then maybe two or three months after she’s [enrolled in services] officially. I would have really appreciated that because…– it was just too much” (3). This recommendation represents a departure from the timeline of the larger study, in which families only worked with navigators from the time of identified concern for ASD through 100 days after diagnostic ascertainment.

One parent suggested changing the dosage of the intervention from three core visits with the navigator to monthly check-ins: “Once a month just call the people that have autism – you know, they might have a lot of questions. Because usually when you try to call your doctors, it’s hard to get them on the phone (…) If you have a Family Navigator that would be calling every month you can kind of tell them certain things and they help you out” (19). The goal of this adaptation might be to improve fit with recipient needs and would also involve changes at the supervision team, navigator, and family levels of delivery.

Changes in packaging or materials (e.g., introduction to the navigator) were also suggested. Parents and navigators suggested that the primary care physician (PCP) make a real-time introduction to the navigator. One navigator specifically suggesting a warm handoff: “Let’s say once [families are] referred, the doctors say, ‘Okay, so I’m gonna refer you to DBP and I’m just gonna connect you to a navigator who’s gonna help you throughout the process. She’s gonna come into the room’” (11). On the other hand, one parent suggested that PCPs should not make the introduction to the navigator: “I personally don’t think I would prefer [being introduced to the navigator by my PCP] because I might be, you know, getting – I might be having a lot going on as is with the appointment” (2).

Many participants endorsed lengthening/extending the time navigators work with families past the 100 days following diagnostic ascertainment. A parent of a 6-year-old child said, “As the kids – as they grow up – they give you changes. So you expect new things coming up and you’re not familiar with this new behavior, so you don’t know how to handle it” (19).

The remaining content recommendations reflected tailoring existing components of the intervention and included: ensuring sufficient supervision of navigators, especially for difficult cases; and improved communication between the PCP, the DBP, and the navigator. As one navigator said: “I think incorporating the family navigator into the entire process. You know, having more communication with the primary care doctors, having the family navigator be a part of that medical team, and keeping them. They can be a link between the family and the organization itself because the family might say something to the navigator that they wouldn’t necessarily mention to their doctor. Having that constant communication, having that network of people together. I think it could really work in the best interest of the families if there’s that ongoing communication and embracing family navigation as part of another medical service that can be provided” (8). Both high quality supervision that includes case review and ongoing trainings, as well as effective communication between the PCP, the DBP, and the navigator are both core components of FN so these two adaptations are aligned with fidelity optimization.

Context adaptations

Context adaptations addressed changes to the delivery of FN in terms of personnel and setting. Navigators suggested that future navigators have an educational background in social work or psychology and experience working in home settings. In addition, navigators recommended special attention to the transition process (e.g., done in-person) in cases when there is staff turnover. Two parents and one navigator suggested that navigators should have personal experience with ASD. One parent said, “I feel like people underestimate the value of personal experience. So, if you’re working with somebody [who] has a family member with autism or works with children with autism, that’s really invaluable in the process (…) You can just kind of tell when people don’t know what they’re talking about. So I feel like it really helps when somebody is understanding because of personal experience” (19).

Recommendations also emphasized the need for increased integration of FN into existing healthcare and service systems. For example, parents and navigators suggested that FN should be integrated and/or co-located into primary care, which was beyond the scope of the original FN intervention design. A parent said, “[Families] trust their doctor better than anybody. So when the doctor refers them to somebody, they will take it seriously – more serious than if it was anybody else” (1). Another parent suggested that FN should exist across healthcare systems and hospitals.

The remaining recommendations for changes to context reflect existing components of the intervention. Parents and navigators suggested that navigators be bilingual/bicultural and come from the same community and local culture as the families they serve. One navigator said, “I’ve had some moms say to me…point out to me my whiteness…my master’s degrees …and I totally understand and I… I think I was able to get past that, (…) but I think that ideally it would be someone more in the community” (2). Parents and navigators also suggested that navigators should quickly connect with families following referral to FN and navigator home visits should be offered.

Training and evaluation

Recommendations designated as training and evaluation modifications focused on improving support for navigators. These recommendations were predominantly made by navigators and represented recommendations for fidelity optimization. Navigators suggested more training on behavior change strategies such as motivational interviewing (MI): “I think probably – yeah, [I could have been better prepared by] getting more MI skills. I think problem solving skills too… Because you’re working with different families, so obviously the situations that the families are going through is a bit different from one another” (4). Navigators also suggested more training on local service systems: “Since I was in [other state] coming to Massachusetts, this is something different. So, probably [supplemental security income (SSI)] will be different from how [other state] SSI is. So, probably the different public benefits and having applied for them and the eligibility criteria might be different. So, maybe in that sense I hope – I wish I would’ve gotten more training in that sense – on the social services” (2).

Implementation and scale-up

Recommendations categorized as implementation and scale-up adaptations emphasized increasing access to FN by expanding eligibility criteria and improving publicity about FN availability. The recommendations all represented true adaptations to FN.

Three parents and one navigator suggested expanding eligibility to families with children with other intellectual or developmental disabilities. A parent said, “I think [the navigator] helps a lot of people (…) At any point we need their help, but not only for children with autism, but also for children who are deaf-mute and so on. I think it would be very helpful for us parents with children like that” (11). Thirteen parents and one navigator recommended increasing the reach of the intervention in general. A parent said, “I don’t care if it’s autism, cancer, whatever. I feel like any type of family that is dealing with some type of devastating news about their child would benefit from a family navigator” (19). Two parents and one navigator suggested specifically expanding FN for families who do not speak English and/or are undocumented. A Spanish-speaking parent said, “In the group my son was sent to, I met several moms who didn’t know how to go to therapy in [city]. They didn’t know how to go or what to do. And they spoke Spanish. So, people like that could receive guidance and help” (10).

Multiple parents made recommendations for disseminating FN through focused marketing or publicity on media platforms such as local television. One parent said, “I think maybe there should be flyers… or more broadcast, like maybe on TV… for somebody who don’t know or haven’t went to a clinic and know that it’s out there to have help from them” (1). Another parent suggested allowing parents to refer other parents who might benefit from navigation: "I think that improving the program would mean to check if there are more people who need it and get in touch with them. Because some of us need it but we don’t know about it. (…) If you give us permission to talk about them, I would be one of those people who could tell other people about the program" (5).

Discussion

Key findings

The current study investigated the recommendations of 21 parents of children with ASD and 7 navigators who participated in a RCT of FN. Through an iterative qualitative study design, recommendations for improvements to FN were elicited from parents who received FN and navigators who provided the intervention in the trial. This study builds upon prior research evidence to support FN among diverse families seeking to achieve diagnostic resolution for their child with ASD [9,10,11,12]. We provide concrete areas for the adaptation and refinement of the FN intervention based on parent and navigator experiences.

Parents and navigators identified 38 recommendations for adaptations to the content (n = 18), context (n = 10), implementation and scale-up (n = 6), and training and evaluation (n = 4) of FN. This distribution is in line with the literature: a systematic review on adaptations of evidence-based public health interventions found that content adaptations were most common, followed by context modifications and cultural adaptations [28]. Overall, recommendations highlighted a desire for expansion of FN: adding new navigator responsibilities, improving integration within the medical team, enhancing navigator training, and reaching more families for longer periods of time. This expansion would likely increase costs, a topic that did not emerge in parent or navigator interviews, but that should be of consideration in future research, and will be probed further in future data collection with family navigation researchers, organizational, and system leaders.

True adaptations vs. recommendations reflecting existing components of FN

An unexpected finding was that nine of the 38 recommendations reflected existing components of the intervention. For example, navigators suggested adding more training on behavior change strategies, such as MI, and local service systems. This recommendation reflects the first core component of FN: “Intensive initial training to navigators on MI, navigation, problem-solving approaches, and ASD diagnostic and treatment services” [8]. Thus, the recommendation represents a need to deliver the intervention with better fidelity, rather than an opportunity to adapt FN. Although the larger RCT examined fidelity through multiple lenses, the implementation recommendations were not measured in the trial. This suggests that eliciting participant insights through periodic reflections during implementation could improve fidelity as challenges arise, rather than post-implementation [29].

While the remaining 29 recommendations represented true adaptations that participants believe may improve the intervention, future research should consider whether such changes would be consistent or inconsistent with intervention fidelity, and the potential for adaptations to add to or detract from the effectiveness of the intervention. For example, if FN were adapted to focus on care transition points, such as the initiation of EI services or the transition to school services, as suggested by parents, this would change the goal of the intervention and potentially alter what would be considered a successful outcome. If the navigator was able to get a family through the diagnostic process and enrolled in autism-specific services through EI programs, this was seen as a success in the larger RCT. However, interviews with parents a few years after study completion brought up an important point about sustained access to services. Multiple parents mentioned difficulties about transitioning from EI services to services throughout school-age. Given that EI often ends at 3 years and kindergarten usually begins at 5 years, parents of children with ASD must advocate for the child to receive services in this critical window. Thus, although these interviews identified challenges post-implementation that might have been resolved had they been identified sooner, they also uncovered additional challenges that parents faced related to the primary outcome (early identification of autism and early intervention services). Future research could thoughtfully consider multiple additional measures of success with time, or the possibility to extend autism FN to a lifespan model.

Systems-level barriers

Given that cost can be an important barrier to navigation interventions [30], future studies might consider assessing the costs associated with these modifications and how to best expand FN while keeping a favorable cost–benefit balance. A current study, for example, is examining the most beneficial components of FN for families with young children with behavioral concerns using the Multiphase Optimization Strategy (MOST) framework [31]. It is also possible that such modifications would create additional longer-term cost saving to health care systems by balancing the added cost of FN with the cost-saving benefit of addressing developmental or behavioral concerns early, thus increasing access to supportive early intervention services, and decreasing later health-related costs. On the other hand, it is possible that making such modifications would lead to greater cost without discernable benefit, underlining the need for further refinement and testing of the intervention.

One potential modification that emerged several times was identifying characteristics of families that might benefit most from working with a navigator, often described as a “personalized” or “precision” approach [32]. For example, one parent suggested that they did not need additional support of the navigator. This parent had family members with ASD and was familiar with the symptoms, so although they had a positive view of the intervention, they felt that it was not necessary for them. Another parent suggested that members of her predominantly Spanish-speaking community might experience additional benefit from the intervention. Adapting FN implementation to engage a targeted approach – for example focusing on families with limited knowledge of child development and/or ASD, or whose native language is not English – might improve fit between the navigator and the family, helping to overcome implementation challenges, and creating a more cost-effective intervention.

Specific recommendations for intervention adaptation

The model of FN for autism being studied in this paper aims to support parents in identifying and overcoming barriers to reaching diagnostic ascertainment, as well as in other challenges that might arise during this time period [8]. One of the most common recommendations from both parents and navigators, however, was to lengthen the intervention beyond 100 days post diagnostic ascertainment. Multiple parents mentioned challenges that outlasted diagnostic ascertainment. One parent said, “I’m very grateful to have been able to work with her. And unfortunately (…) I wish I still could because there are things right now that I want to – I’m not too certain about and I want to have more clarification but unfortunately, I don’t have her as a coordinator anymore” (17). This demonstrates the logistical challenges that families face post-diagnosis and suggests navigation might mitigate some of these challenges. Future research may consider identifying for whom an additional time period for FN would be most beneficial.

These findings are particularly important in the context of ASD considering the amount of parenting stress related to having a child with ASD, stigma, and other difficulties families of children with ASD face as they enter school and navigate the education system [33,34,35]. Research shows that parents of children with documented concern for ASD experience higher levels of stress than parents of children with other developmental concerns or no concerns [36]. Qualitative evidence from the current study overwhelmingly suggested that FN was able to alleviate parent stress through emotional support.

Context

Parents in the current study also cited hardships related to other social determinants of health including housing insecurity, lack of employment, and immigration status, and how navigators were able to help in these areas. Hardships described by parents reflect the broader need for support for parents of children with disabilities. They also reflect an ongoing discussion about the importance of navigator and/or community health worker (CHW) qualifications, which have been conflicting in the literature. Tension exists regarding whether lived experience (e.g., same culture, child with ASD) or having advanced formal training is more important for intervention success.

Strengths and limitations

A strength of this study was its use and advancement of the implementation science framework FRAME. Although many studies capture provider perspectives on adaptation of interventions, this paper highlights the consumer voice. Additionally, rapid analysis was used for faster turnaround of results, which allowed for further investigation of adaptations. This study was also strengthened by its focus on traditionally underserved families.

A limitation of this study was that most parents were interviewed a few years after their participation in FN. As a result, multiple parents had forgotten details about their experience and in some cases, their navigator. Given that navigation is novel in many settings and navigators offer help across multiple areas of need, parental confusion is not surprising. Another limitation of this study was that parents of children who were not diagnosed with ASD in the larger study but still received FN were beyond the scope of this study and thus excluded. Future studies could examine how families who participated in an intervention focused on ASD but whose children received other diagnoses benefitted or experienced potential harm (e.g., unnecessary stigma or stress) from the intervention. This could also help us better understand how FN could be used for children with other developmental and intellectual disabilities.

A final limitation of this study was that inclusion of other stakeholder groups, such as supervision teams, healthcare providers, and clinic staff, was not feasible. Interviews with members of these other groups would likely identify new recommendations as well insight into recommendations made by parents and navigators. It is also likely that these groups might identify modifications associated with cost reduction, a key area that was not raised in this study.

Conclusion

This study demonstrates the value of embedding study of adaptation in intervention research. Despite proven effectiveness of FN, stakeholders had many recommendations for adaptation. Recommendations made by parents and navigators have the potential to inform improvement of existing navigation programs and development of new programs in similarly diverse populations. More generally, this study shows the value in continually eliciting feedback from parents and navigators in order to refine and optimize FN efforts and improvements. This is particularly important for improving equity of the intervention across populations. This is especially important given an increased national focus on expanding the mental health through different service models, such as FN, for racially and ethnically diverse families [13]. Recently, the Biden Administration released their mental health research priorities, which included a focus on understanding how to enhance the diversity of the mental health workforce through training paraprofessionals and community health worker in evidence-based practices, which could include FN. By partnering with stakeholders, including the navigators themselves, it is more likely these interventions will fit the communities they are serving and be scalable and sustainable.
