Abstract
There is a great demand for quality early intervention services for autistic children and their families. Caregiver-mediated interventions are critical components of evidence-based early intervention. However, their implementation in publicly funded systems is often done with poor fidelity. Qualitative evidence suggests that family characteristics impact clinicians’ use of caregiver-mediated intervention coaching strategies. We estimated associations between family characteristics and clinicians’ use of a caregiver-mediated intervention in a publicly funded early intervention system, leveraging data from a pilot randomized trial. Data were collected from 12 clinicians and 34 families. We used multiple linear regression models to estimate associations. The association between household income and clinicians’ overall coaching fidelity demonstrated a quadratic trend (
Lay abstract
There is a high demand for quality early intervention services for autistic children and their families. A key part of effective early intervention is teaching caregivers how to support their child’s development through caregiver-mediated interventions. However, in publicly funded programs, these strategies are often not followed correctly. Some studies suggest that family characteristics may influence how well clinicians apply these coaching methods. In this study, we explored the connection between family factors, like household income and language spoken at home, and the way clinicians coached families. We found that clinicians used coaching strategies less consistently with both lower- and higher-income families compared to middle-income ones. In addition, families that spoke only English at home received less consistent coaching than those who spoke other languages. These findings highlight the complex relationship between family background and how early intervention services are delivered, suggesting a need for further research.
Keywords
Early intervention (EI) services are critical to enhance autistic children’s outcomes (Fuller & Kaiser, 2020; Reichow & Wolery, 2009; Zwaigenbaum et al., 2015). Federal policy mandates that EI help caregivers support their child’s development (Individuals With Disabilities Education Act (IDEA), 2004). Caregiver-mediated interventions (CMIs) involve clinicians coaching caregivers to use strategies that foster children’s development. CMI improves children’s social skills and communication, and reduces disruptive behavior (Cheng et al., 2023; Hume et al., 2021).
In community-based studies of CMI, outcomes tend to be worse than in university-based studies (Brookman-Frazee et al., 2012; Green et al., 2022), at least in part because community clinicians are less likely to coach caregivers (Aranbarri et al., 2021; Pellecchia et al., 2022). When clinicians coach caregivers in the community, it is often with lower fidelity than observed in university-based studies (Pellecchia et al., 2022). Clinicians vary in their intentions to implement specific coaching components (Lawson et al., 2022; Pellecchia et al., 2024), with some used more than others (Pellecchia et al., 2023b).
Racially minoritized and socioeconomically disadvantaged autistic children have less access to and receive lower-quality behavioral healthcare than their White (Begeer et al., 2009; Liu et al., 2023; Magaña et al., 2012, 2013) and socioeconomically advantaged peers (Carr et al., 2016; Fountain et al., 2012). This may be in part due to clinicians’ perceptions, as well as the experienced barriers related to family characteristics and living conditions, that hinder CMI coaching (Straiton et al., 2021; Tomczuk et al., 2022).
The present observational study leverages data from a community-based trial of a CMI (

This study comprised a secondary analysis of data collected from a pilot randomized trial of
Setting
The parent study was conducted in publicly funded EI agencies during the COVID-19 pandemic.
Project ImPACT
Participants
Participants included community EI clinicians and caregivers and children from the clinicians’ caseloads. Upon enrollment, children were less than 36 months of age and were either at high likelihood of or diagnosed with autism.
Measures and procedures
Clinician and family dyad characteristics measures
Participants completed demographic questionnaires. Age, education, racial/ethnic identity, household annual income, and language were provided categorically. Household size was reported as a continuous variable.
Outcome measures
Trained raters evaluated clinicians’ use of coaching strategies during sessions using two measures:
Video recording procedures
Fidelity for both measures was scored by trained research staff. Twenty percent of videos was double-coded. Mean inter-rater agreement was 87% for
Data analysis
Analyses were conducted using R version 4.1.2 (R Core Team, 2021). We examined family characteristics using descriptive statistics. Families’ reported racial and ethnic identities were categorized into one of two groups: “racially/ethnically minoritized families” or “White, non-Hispanic families.” Household language was aggregated into two groups: “exclusively English-speaking household” or “other languages household,” meaning a non-English language was spoken in the home.
We calculated descriptive statistics for both fidelity measures. Correlations between mean total scores and subcomponents of fidelity measures were computed as a basic assessment of construct convergence between the two measures (Campbell & Fiske, 1959; Strauss & Smith, 2009). Correlations between family characteristics and total scores were computed (e.g. Pearson
We conducted analyses between family characteristics and

This study is an exploratory analysis with a small sample size. Therefore, results should be interpreted with caution. Family characteristic variables were not selected a priori, limiting, for example, income ranges. Yet, household income association with coaching fidelity demonstrated consistency across
Conclusion
We provide preliminary evidence that family characteristics and clinicians’ coaching fidelity are associated. This study responds to calls for more inclusive autism research by engaging and enrolling diverse, marginalized families, with the goal of advancing health equity (Machalicek et al., 2022; Maye et al., 2022; Straiton et al., 2024). Future research should collect more comprehensive family characteristic data. This study sets the stage for research to ameliorate and improve associations between family characteristics, circumstances, and clinicians’ caregiver coaching.
